PHP - Not Establishing Correct Mysql Limit
I feel like a tard for having to ask this, but I've spent way too much time trying to figure this out, so i've brought it to you guys.
I have run into a an error running a while loop off a query: $rowcount= mysql_query("SELECT COUNT(*) FROM `shoutbox`"); $count = mysql_fetch_array($rowcount); $count = $count['COUNT(*)']; $said = mysql_query("SELECT * FROM shoutbox ORDER BY date ASC LIMIT ('$count' - 5),'$count' "); while($row = mysql_fetch_array( $said )){ //line 14 in the code echo $row['shouter'].': '.$row['contents'].'<br />'; } Code: [Select] mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/mahngiel/public_html/shout.php on line 14This script works when I remove the limit counts, but then I have to descend the order and things are not in the position I want them in. I'm sure the problem is the limit vars, but dunno which way to go to fix it. thanks Similar TutorialsIt's pretty simple to see what I am trying to do here. For some reason all results in the table are the same exact cityName replacing all existing records. The echoed results are correct. I've include a small dump of my table as well. $query = "SELECT cityName FROM sys_city_dev_2"; $resource = mysqli_query($cxn, $query) or die("MySQL error: " . mysqli_error($cxn) . "<hr>\nQuery: $query"); while($result = mysqli_fetch_assoc($resource)) { $nox = $result['cityName']; $toUpper = ucfirst($nox); echo "$toUpper" . "<br />"; $setString = "UPDATE sys_city_dev_2 SET cityName = '" . $toUpper ."' WHERE cityName != ''"; mysqli_query($cxn,$setString); } 100 Records of table dump (pre running my script above): -- -- Table structure for table `sys_city_dev_2_backup` -- CREATE TABLE IF NOT EXISTS `sys_city_dev_2_backup` ( `ID` int(11) NOT NULL AUTO_INCREMENT, `Mid` int(11) NOT NULL DEFAULT '0', `cityName` varchar(30) NOT NULL DEFAULT '', `forder` int(4) NOT NULL DEFAULT '0', `disdplay` int(4) NOT NULL DEFAULT '0', `cid` int(11) NOT NULL DEFAULT '0', PRIMARY KEY (`ID`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=113970 ; -- -- Dumping data for table `sys_city_dev_2_backup` -- INSERT INTO `sys_city_dev_2_backup` (`ID`, `Mid`, `cityName`, `forder`, `disdplay`, `cid`) VALUES (84010, 1, 'dothan', 0, 0, 0), (84011, 1, 'alabaster', 0, 0, 0), (84012, 1, 'birmingham', 0, 0, 0), (84013, 2, 'flagstaff', 0, 0, 0), (84014, 1, 'auburn', 0, 0, 0), (84015, 1, 'florence', 0, 0, 0), (84016, 1, 'gadsden', 0, 0, 0), (84017, 1, 'huntsville', 0, 0, 0), (84018, 1, 'mobile', 0, 0, 0), (84019, 1, 'montgomery', 0, 0, 0), (84020, 1, 'tuscaloosa', 0, 0, 0), (84021, 2, 'mohave valley', 0, 0, 0), (84022, 2, 'phoenix', 0, 0, 0), (84023, 2, 'prescott', 0, 0, 0), (84024, 2, 'sierra vista', 0, 0, 0), (84025, 2, 'tucson', 0, 0, 0), (84026, 2, 'yuma', 0, 0, 0), (84027, 3, 'bakersfield', 0, 0, 0), (84028, 3, 'chico', 0, 0, 0), (84029, 3, 'fresno / madera', 0, 0, 0), (84030, 3, 'gold country', 0, 0, 0), (84031, 3, 'humboldt county', 0, 0, 0), (84032, 3, 'imperial', 0, 0, 0), (84033, 3, 'inland empire', 0, 0, 0), (84034, 3, 'los angeles', 0, 0, 0), (84035, 3, 'alhambra', 0, 0, 0), (84036, 3, 'merced', 0, 0, 0), (84037, 49, 'fayetteville', 0, 0, 0), (84038, 49, 'fort smith', 0, 0, 0), (84039, 49, 'jonesboro', 0, 0, 0), (84040, 49, 'little rock', 0, 0, 0), (84041, 49, 'arkadelphia', 0, 0, 0), (84042, 49, 'texarkana', 0, 0, 0), (84043, 3, 'modesto', 0, 0, 0), (84044, 3, 'alta sierra', 0, 0, 0), (84045, 3, 'alpine', 0, 0, 0), (84046, 3, 'pedley', 0, 0, 0), (84047, 3, 'redding', 0, 0, 0), (84048, 3, 'alondra park', 0, 0, 0), (84049, 3, 'sacramento', 0, 0, 0), (84050, 4, 'canon city', 0, 0, 0), (84051, 3, 'san luis obispo', 0, 0, 0), (84052, 3, 'santa barbara', 0, 0, 0), (84053, 3, 'stockton', 0, 0, 0), (84054, 3, 'aliso viejo', 0, 0, 0), (84055, 3, 'visalia', 0, 0, 0), (84056, 3, 'yuba city', 0, 0, 0), (84057, 4, 'boulder', 0, 0, 0), (84058, 4, 'colorado springs', 0, 0, 0), (84059, 4, 'denver', 0, 0, 0), (84060, 4, 'applewood', 0, 0, 0), (84061, 4, 'pueblo', 0, 0, 0), (84062, 4, 'air force academy', 0, 0, 0), (84063, 5, 'avon', 0, 0, 0), (84064, 5, 'hartford', 0, 0, 0), (84065, 5, 'new haven', 0, 0, 0), (84066, 5, 'ansonia', 0, 0, 0), (84067, 5, 'fairfield', 0, 0, 0), (84068, 7, 'daytona beach', 0, 0, 0), (84069, 7, 'sebastian', 0, 0, 0), (84070, 5, 'wallingford center', 0, 0, 0), (84071, 8, 'belvedere park', 0, 0, 0), (84072, 7, 'sarasota springs', 0, 0, 0), (84073, 7, 'sandalfoot cove', 0, 0, 0), (84074, 7, 'san carlos park', 0, 0, 0), (84075, 7, 'st. augustine', 0, 0, 0), (84076, 7, 'tallahassee', 0, 0, 0), (84077, 7, 'safety harbor', 0, 0, 0), (84078, 7, 'ruskin', 0, 0, 0), (84079, 8, 'athens-clarke county', 0, 0, 0), (84080, 8, 'atlanta', 0, 0, 0), (84081, 8, 'augusta-richmond county', 0, 0, 0), (84082, 8, 'brunswick', 0, 0, 0), (84083, 8, 'columbus', 0, 0, 0), (84084, 8, 'americus', 0, 0, 0), (84085, 8, 'acworth', 0, 0, 0), (84086, 8, 'valdosta', 0, 0, 0), (84087, 10, 'boise', 0, 0, 0), (84088, 10, 'ammon', 0, 0, 0), (84089, 10, 'moscow', 0, 0, 0), (84090, 10, 'blackfoot', 0, 0, 0), (84091, 10, 'twin falls', 0, 0, 0), (84092, 10, 'meridian', 0, 0, 0), (84093, 10, 'jerome', 0, 0, 0), (84094, 10, 'idaho falls', 0, 0, 0), (84095, 11, 'addison', 0, 0, 0), (84096, 10, 'garden city', 0, 0, 0), (84097, 10, 'eagle', 0, 0, 0), (84098, 10, 'chubbuck', 0, 0, 0), (84099, 10, 'caldwell', 0, 0, 0), (84100, 12, 'bloomington', 0, 0, 0), (84101, 12, 'evansville', 0, 0, 0), (84102, 12, 'fort wayne', 0, 0, 0), (84103, 12, 'indianapolis', 0, 0, 0), (84104, 12, 'muncie / anderson', 0, 0, 0), (84105, 12, 'lafayette / west lafayette', 0, 0, 0), (84106, 12, 'south bend / michiana', 0, 0, 0), (84107, 12, 'terre haute', 0, 0, 0), (84108, 12, 'northwest indiana', 0, 0, 0), (84109, 13, 'ames', 0, 0, 0); How can I limit the amount of time my while loop to only show the first 4 rows of my SQL table?
I am using this code to loop my whole table:
while($row = $results->fetch(PDO::FETCH_ASSOC)) { echo ' <li>Mileage: '.number_format($row["Mileage"]).'</li> <li>Engine size: '.$row["EngineSize"].'cc</li> ';} ?>I only want to loop through the first 4 rows of my SQL table, I then want to duplicate the same code but start at the 5th row until the 8th row of the table, how can I do this? Thanks, Nick Hi. I'm trying to make a sort of a forum, and this is the part of the code that needs to be changed, only I don't know how. Code: [Select] mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); $sql="SELECT * FROM $tbl_name ORDER BY id DESC"; // OREDER BY id DESC is order result by descending $result=mysql_query($sql); ?> <table width='50%' border="0" align="center" cellpadding="3" cellspacing="1"> <?php $limit=10; $page=0; $numrows = mysql_num_rows($result); $pages = intval($numrows/$limit); if ($numrows % $limit) { $pages++;} $current = ($page/$limit) + 1; if (($pages < 1) || ($pages == 0)) { $total = 1;} else { $total = $pages;} $result = mysql_query("SELECT * FROM $tbl_name ORDER BY id DESC LIMIT $page,$limit"); while($rows=mysql_fetch_array($result)){?> <tr><td><font size="+2"><a href="view_topic.php?id=<? echo $rows['id']; ?>"><? echo $rows['topic']; ?></a><BR></font></td> <td width='0*'><? echo $rows['datetime']; ?></td></tr> <tr><td><? echo substr($rows['detail'], 0, 250)."..."; ?> <a href="view_topic.php?id=<? echo $rows['id']; ?>"><? echo "Citeste mai mult";} ?></a> </td></tr> <tr><tr><td> <? if ($page != 0) { // Don't show back link if current page is first page. $back_page = $page - $limit; echo("<a href=\"$PHP_SELF?query=$query&page=$back_page&limit=$limit\">back</a> \n");} for ($i=1; $i <= $pages; $i++) // loop through each page and give link to it. { $ppage = $limit*($i - 1); if ($ppage == $page){ echo("<b>$i</b>\n");} // If current page don't give link, just text. else{ echo("<a href=\"$PHP_SELF?query=$query&page=$ppage&limit=$limit\">$i</a> \n");} } if (!((($page+$limit) / $limit) >= $pages) && $pages != 1) { // If last page don't give next link. $next_page = $page + $limit; echo(" <a href=\"$PHP_SELF?query=$query&page=$next_page&limit=$limit\">next</a>");} ?> </td></tr></tr><?php mysql_close(); ?> </table> I made a database with 4 fields and 11 entries. The script shows the last 10 entries just as it should, but when I click on the 'next' button, nothing happens (it should show the first entry, but it just refreshes the page, and still the last 10 entries/1st page are shown). I think it has something to do with the link, but I can't figure out what exactly. Can someone help, or at least give me a hint? Thanks in advance. Bye. Let's say I have 1 table and 100 rows in this table. The table is simple and only contains an Auto Increment ID field and a load_count field. Hello! I want to make the users in the website able only to upload, for example, 1 GB, so that when a user finishes the 1 GB available for his files, he cannot upload more files. I know how to set up upload limit for a single file in the upload page, or even globally for anyone to upload. But I would like to know how to make each user has specific capacity, and how it is updated so that if he uploads 0.5 GB he has only 0.5 GB left. I thought of creating a column in the `users` or something concerning upload limit that I will set it (one GB for example). If I will do that, how will I be able to determine how much he uploaded? Any help would be appreciated. Thank you! I have these two tables...
schedule (gameid, homeid, awayid, weekno, seasonno)
teams (teamid, location, nickname)
This mysql query below gets me schedule info for ALL 32 teams in an array...
$sql = "SELECT h.nickname AS home, a.nickname AS away, h.teamid AS homeid, a.teamid AS awayid, s.weekno FROM schedule s INNER JOIN teams h ON s.homeid = h.teamid LEFT JOIN teams a ON s.awayid = a.teamid WHERE s.seasonno =2014"; $schedule= mysqli_query($connection, $sql); if (!$schedule) { die("Database query failed: " . mysqli_error($connection)); } else { // Placeholder for data $data = array(); while($row = mysqli_fetch_assoc($schedule)) { if ($row['away'] == "") {$row['away']="BYE";} $data[$row['homeid']][$row['weekno']] = $row['away']; $data[$row['awayid']][$row['weekno']] = '@ '.$row['home']; } }However, I only want to get info for one specific team, which is stored in the $teamid variable. This should be very easy, right? I have tried multiple things, including this one below (where I added an AND statement of "AND (h.teamid=$teamid OR a.teamid=$teamid)"), but this one still outputs too much... $sql = "SELECT h.nickname AS home, a.nickname AS away, h.teamid AS homeid, a.teamid AS awayid, s.weekno FROM schedule s INNER JOIN teams h ON s.homeid = h.teamid LEFT JOIN teams a ON s.awayid = a.teamid WHERE s.seasonno =2014 AND (h.teamid=$teamid OR a.teamid=$teamid)"; $schedule= mysqli_query($connection, $sql); if (!$schedule) { die("Database query failed: " . mysqli_error($connection)); } else { // Placeholder for data $data = array(); while($row = mysqli_fetch_assoc($schedule)) { if ($row['away'] == "") {$row['away']="BYE";} $data[$row['homeid']][$row['weekno']] = $row['away']; $data[$row['awayid']][$row['weekno']] = '@ '.$row['home']; } }Below is the array that the above outputs. In a nutshell, all I want is that 1st array ([1]) which has, in this example, the Eagles full schedule. It's not giving me too much else and I guess I could live with it and just ignore the other stuff, but I'd rather be as efficient as possible and only get what I need... Array ( [1] => Array ( [1] => Jaguars [2] => @ Colts [3] => Redskins [4] => @ 49ers [5] => Rams [6] => Giants [7] => BYE [8] => @ Cardinals [9] => @ Texans [10] => Panthers [11] => @ Packers [12] => Titans [13] => @ Cowboys [14] => Seahawks [15] => Cowboys [16] => @ Redskins [17] => @ Giants ) [27] => Array ( [1] => @ Eagles ) [28] => Array ( [2] => Eagles ) [4] => Array ( [3] => @ Eagles [16] => Eagles ) [14] => Array ( [4] => Eagles ) [15] => Array ( [5] => @ Eagles ) [3] => Array ( [6] => @ Eagles [17] => Eagles ) [] => Array ( [7] => @ Eagles ) [16] => Array ( [8] => Eagles ) [25] => Array ( [9] => Eagles ) [11] => Array ( [10] => @ Eagles ) [7] => Array ( [11] => Eagles ) [26] => Array ( [12] => @ Eagles ) [2] => Array ( [13] => Eagles [15] => @ Eagles ) [13] => Array ( [14] => @ Eagles ) ) I have a commenting system and i have a limit of a certain number of comments to be shown. What i want to do is have a button on the bottom of the page at the end of the comments that are showing and when you click it ajax loads the next certain number of of rows (but not all of them),and then you click it again and it shows more of them, etc. So for example. comment 1 comment 2 comment 3 comment 4 --click button--(loads 4 more)--- comment 5 comment 6 comment 7 comment 8 --click button--(loads 4 more)-- comment 9 comment 10 comment 11 comment 12 etc. until there are no more rows. what's the best way to do this? (I know how to do the ajax and all, i just need help with the script to select the rows) Thanks. I am building a commenting system, it's sort of like facebooks comments. I have it right now so it loads the first last 3 comments in the database, and then there's a button to view all comments. I have it working fine, except when you add another comment to it, and then click the view all comments, This is the script that loads onload showing the last 3 comments $limit = 3; $query5 = mysql_query("SELECT * FROM sub_comments WHERE status_id='$id' ORDER BY id DESC LIMIT $limit"); This is the php script that runs when you click view more //($start_id would be 3 in this case) $query5 = mysql_query("SELECT * FROM sub_comments WHERE status_id='$comment_id' ORDER BY id DESC LIMIT $start_id, 1000"); so to try to show you what's happening: OnLoad--------------------------------|---When you add more comments, (let's just say u add 1 comment before u click view comments)---- comment 9 --------------------------| comment 10 comment 8 --------------------------| comment 9 comment 7 --------------------------| comment 8 ------------------------------------------| comment 7 ----to be loaded onclick-------------|------What's loaded onclick--- comment 6 --------------------------| comment 7 comment 5 --------------------------| comment 6 comment 4 --------------------------| comment 5 comment 3 --------------------------| comment 4 comment 2 --------------------------| comment 3 comment 1 --------------------------| comment 2 ------------------------------------------| comment 1 (see how "comment 7" is being shown twice in a row) Unless buffer overflows or breaking out of code to perform a new command are problems that have been solved.... I am trying to figure out the proper PHP method for setting a boundary on a variable within a script. I have this variable $name which is fed a value from $_POST['name'] from a form field. Now this form field is limited in the HTML to accept only 20 characters, but someone could easily edit the form or outgoing post data. So I want to know how to limit the variable size in the script. In other languages it could be something like this: var name(20). So how do I do that in PHP? This code works fine without the LIMIT 5, but it lists all the results. With the LIMIT Code: [Select] $query = 'SELECT * FROM wp_playerRank WHERE year="2011" LIMIT 5 ORDER BY rankClass ASC'; $results = mysql_query($query); while($line = mysql_fetch_assoc($results)) { Here is the error I'm getting: Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /home/jwrbloom/public_html/resources/players/rank2011_top5.php on line 26 im using the floowing code to pull all alerts from the database. as you can see i have 3 types of alertsd. Profile alerts, forum alerts and topic alerts. They are sorted and placed on the screen under their respective header. However i want to limit it so it only displays 4 of each type of alert. I cant use LIMIT in the query because that would limit all alerts meaning only 4 alerts in total would show up and i just need to limit each alert type. any ideas? $alert_query = $link->query("SELECT a.a_aid, a.a_alert_type, a.a_time_alerted, a.a_fid, a.a_poster, a_alert_read, a.a_tid, c.f_name as cat_name, f.f_fid, f.f_name, t.t_name, u.u_avatar, u.u_avatar_cropped FROM ".TBL_PREFIX."alerts as a LEFT JOIN ".TBL_PREFIX."forums as f ON (f.f_fid = a.a_fid) LEFT JOIN ".TBL_PREFIX."topics as t ON (t.t_tid = a.a_tid) LEFT JOIN ".TBL_PREFIX."forums as c ON (c.f_fid = f.p_id) LEFT JOIN ".TBL_PREFIX."users as u ON (u.u_username = a.a_poster) WHERE a.a_user_name = '$user_name' ORDER BY a_time_alerted ") or die(print_link_error()); $alert_info = $alert_query->fetchAll(); $pm_alert_list = ''; $num_pm_alerts = 0; $num_forum_alerts = 0; $num_topic_alerts = 0; foreach($alert_info as $key => $val) { $alert_info[$key]['a_alert_read'] == 0 ? $color = '#f5dfaf' : $color = '#f4f4f4'; // if alert is a profile message alert if($alert_info[$key]['a_alert_type'] == 1) { $pm_alert_list .= '<dd style="background:'.$color.';" class="alert" id="alert-'.$alert_info[$key]['a_aid'].'"><p class="alert_intro">'; $pm_alert_list .= '<input type="checkbox" class="pm_checkbox" id="pm_checkbox-'.$alert_info[$key]['a_aid'].'" />'.profile_link($alert_info[$key]['a_poster']).' posted on your wall</p>'; $pm_alert_list .= '<p class="alert_time"> on '.asf_date($alert_info[$key]['a_time_alerted'],'full').'</p>'; $pm_alert_list .= '</dd>'; $num_pm_alerts++; } if($alert_info[$key]['a_alert_type'] == 2) { $forum_alert_list .= '<dd style="background:'.$color.';" class="alert" id="alert-'.$alert_info[$key]['a_aid'].'"><p class="alert_intro">'; $forum_alert_list .= '<input type="checkbox" class="pm_checkbox" id="pm_checkbox-'.$alert_info[$key]['a_aid'].'" /><strong><a href="'.$config['asf_root'].'category/'.create_url($alert_info[$key]['cat_name']).'/forum/'.create_url($alert_info[$key]['f_name']).'">'.$alert_info[$key]['f_name'].'</a></strong> has a new topic</p>'; $forum_alert_list .= '<p class="alert_time"> '.asf_date($alert_info[$key]['a_time_alerted'],'full').'</p>'; $forum_alert_list .= '</dd>'; $num_forum_alerts++; } if($alert_info[$key]['a_alert_type'] == 3) { $topic_alert_list .= '<dd style="background:'.$color.';" class="alert" id="alert-'.$alert_info[$key]['a_aid'].'"><p class="alert_intro">'; $topic_alert_list .= '<input type="checkbox" class="pm_checkbox" id="pm_checkbox-'.$alert_info[$key]['a_aid'].'" /><strong><a href="'.$config['asf_root'].'category/'.create_url($alert_info[$key]['cat_name']).'/forum/'.create_url($alert_info[$key]['f_name']).'/topic/'.create_url($alert_info[$key]['t_name']).'">'.$alert_info[$key]['t_name'].'</a></strong> has a new post</p>'; $topic_alert_list .= '<p class="alert_time"> '.asf_date($alert_info[$key]['a_time_alerted'],'full').'</p>'; $topic_alert_list .= '</dd>'; $num_topic_alerts++; } } Hello friends, if i've database table (mytable) has the following ids 1 2 3 4 5 6 and i want to get it with limit the first (1 to 3 ) only Code: [Select] $sql ="select * from mytable LIMIT 3"; this will show the first 3 (1,2,3) how then i write code that shows which is after 3 so it shows me 4 5 6 and if there any way i can say Code: [Select] $sql ="select * from mytable LIMIT (first half of ids)"; and (shows 1,2,3..ect till half) Code: [Select] $sql ="select * from mytable LIMIT (second half of ids)"; will (shows 4,5,6...ect till end) thank you hello, I have a form i am using for a raffle that i have weekly. the problem is i want to limit how many times they can register. I am using a basic form that collects name, email, and IP ( which is hidden ). When it gets submitted there is time stamp as well using this date("m/d/y : H:i:s", time() I would like to restict registering by one hour at a time. can you please give me some help with this. I have thought of maybe using cookies, but some of my smarter members can bypass that. So i think i will either use email or IP . any help would be very appreciated Hi, I have a timestamp mysql field that I'm trying to see if something happened within a time limit. The field is updated with the time when the action is complete so I just need to figure out how to see if it's within a time. I currently have a defined variable set titled "MAX_RESPONSE_TIME" and that's in seconds. By default "MAX_RESPONSE_TIME" is equal to 300 seconds. How can I see if a mysql timestamp field is within 300 seconds? Im wondering if someone can shed some light on possibly the best way to do this. I currently have a website which recieves 26000-37000 visits a month. The host got on my case about to many MySql connections and with help from someone here decided a cache system was best. the cache system is now in place and only updates if the cached file is older than 5 days. I am still recieving high connections to my database and wonder if it is spam as i have a search box. the search box once filled in redirects to a page which queries the database for the keyword and displays results and because it was just selecting and not inserting into database i didnt go for the captcha. this is why i suspect spam, I have thought about limiting the amount of search queries per time limit by ip but I am unsure of how to tackle this and if it will help against spam bots? a google search has only found an answer which stores every visitors ip in a database and keeps count there which I cant see the benefit as it is creating more work for the DB. I have thought maybe creating a session variable that increments with every search and when searching checks this value but I am not to sure if this would help as it would be down to cookie settings. can anyone shed some light on a possible solution to this. I am not expecting you to write this for me but for now just to help with the best way to tackle the problem. Thank you for your time. I am in need of a alimit on the explode() fucntion but reading through the php explode manual on php.net there doesn't seem to be one that is right for me. Basically I'm making a command system for a php chat and it has a command called ban. I have code that find out if it is a command or a normal string, I also have code that starts to break up the command into segments that can be places in the database. I want to split up "ban user lengthID "Reason why you were banned"" using explode($string, " ") but I notice that that will also break up the "reason why you are banned". How do I get it to split up the command but NOT thereason why you were banned string? Confusing I know, Please ask any questions that would help me explain it better Thanks in advance! Hi guys I have a problem. I limit the displayed rows by 10 (which works) and then a link saying "next" or "previous" The link itself works, but the site always just displays teh first 10 data entries. What do I do wrong? Thank you! Code: [Select] <?php $host="****"; // Host name $username="****"; // Mysql username $password="****"; // Mysql password $db_name="****"; // Database name $tbl_name="sp_users"; // Table name // Connect to server and select database. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); //$sql="SELECT * FROM $tbl_name ORDER BY user_id"; $sql="SELECT * from sp_users,sp_schools where sp_users.user_id=sp_schools.school_id ORDER BY school_name LIMIT 0, 10"; $result=mysql_query($sql); $num_rows=mysql_num_rows($result); ?> <?PHP //check if the starting row variable was passed in the URL or not if (!isset($_GET['startrow']) or !is_numeric($_GET['startrow'])) { //we give the value of the starting row to 0 because nothing was found in URL $startrow = 0; //otherwise we take the value from the URL } else { $startrow = (int)$_GET['startrow']; } ?> <?PHP //this part goes after the checking of the $_GET var $fetch = mysql_query("SELECT * FROM sp_users,sp_schools where sp_users.user_id=sp_schools.school_id LIMIT $startrow, 10")or die(mysql_error()); ?> <style type="text/css"> <!-- .style2 {font-weight: bold} .style3 { font-family: Arial, Helvetica, sans-serif; color: #000000; } .style10 {font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 10px; color: #000000; } #Layer1 { position:absolute; left:803px; top:36px; width:65px; height:28px; z-index:1; } #Layer2 { position:absolute; left:707px; top:19px; width:143px; height:39px; z-index:1; } #Layer3 { position:absolute; left:247px; top:463px; width:175px; height:53px; z-index:2; } --> </style> <title>User overview</title> </html> <div id="Layer2"> <form action="<?= $_SERVER['PHP_SELF'] ?>" method="post"> <input type="hidden" name="foo" value="<?= $foo ?>" /> <input type="submit" name="submit" value="Refresh" /> </form></div> <div id="Layer3"><?PHP //now this is the link.. echo '<a href="'.$_SERVER['PHP_SELF'].'?startrow='.($startrow+10).'">Next</a>'; ?> <?PHP $prev = $startrow - 10; //only print a "Previous" link if a "Next" was clicked if ($prev >= 0) echo '<a href="'.$_SERVER['PHP_SELF'].'?startrow='.$prev.'">Previous</a>'; ?></div> <table width="779" border="0" align="left" cellpadding="0" cellspacing="1" bgcolor="#996600"> <tr> <td width="777"> <div align="left"> <table width="779" border="1" cellspacing="0" cellpadding="3"> <tr> <td colspan="6" align="center"><div align="center" class="style1 style3"><strong>SchoolPorta.com Users / Total: <?php echo $num_rows ?></strong></div></td> </tr> <tr> <td width="342" align="center"><span class="style2">school</span></td> <td width="62" align="center"><span class="style2">Name</span></td> <td width="104" align="center"><span class="style2">Lastname</span></td> <td width="130" align="center"><span class="style2">Email</span></td> <td width="64" align="center"><span class="style2">Update</span></td> </tr> <?php while($rows=mysql_fetch_array($result)){ ?> <tr> <td><span class="style10"><? echo $rows['school_name']; ?></span></td> <td><span class="style10"><? echo $rows['user_first_name']; ?></span></td> <td><span class="style10"><? echo $rows['user_surname']; ?></span></td> <td><span class="style10"><a href="mailto:<?php echo $rows['user_login']; ?>"><?php echo $rows['user_login']; ?></a></span></td> <td align="center"><a href="update.php?id=<? echo $rows['user_id']; ?>" class="style10">update</a></td> </tr> <?php } ?> </table> </div></td> </tr> </table> <div align="left"> <p> </p> <p> </p> <p> </p> <p> <?php mysql_close(); ?> </p> </div> Hi, This line of code works just fine for me: $sql_quest = 'SELECT id, username FROM user ORDER BY id ASC LIMIT 0, 30'; I want to be able to set the integer values dynamically and I thought something like this would work: $sql_quest = 'SELECT id, username FROM user ORDER BY id ASC LIMIT' . $my_int_value . ',' . $my_int_value + 30; But it doesn't... Any ideas? Alright so I have some code for pagination... the problem is on the middle pages it will display double the number of results... (IE if its supposed to display 5, it displays 10) Code: [Select] // Number of messages per page: $user_message_number = 5; $page = $_GET['page']; if($page <= 1){ $low = 0; $high = $user_message_number; } else { $low = ($page - 1) * $user_message_number; $high = $page * $user_message_number; } $messages = mysql_query("SELECT * FROM messages WHERE recipient='$user_id' ORDER BY id DESC LIMIT $low, $high") or die(mysql_error()); while($pull_messages = mysql_fetch_array($messages)) { // Displays content } That's all of the code that would directly effect the outcome... Any thoughts/comments/suggestions are greatly appreciated. |
