PHP - Paging Records
Similar TutorialsI am having trouble showing reports for a given date range. Currently if I specify something like 11/03/2010 to 11/05/2010 I get results for all years within that month and day such as I may get results for 11/03/2008 11/03/2009 11/03/2010 11/04/2008 11/04/2009 11/04/2010 11/05/2008 11/05/2009 11/05/2010. I am using the following code $result = mysql_query("SELECT * FROM report WHERE date>='$date_begin' and date<='$date_end' ORDER BY 'date'",$db); I use the following format in my date feild mm/dd/yyyy My script is finally working as intended, but I want to add some additional data results. I am trying to resolve how I can display a count of ONLY the records updated by my query: // START :: Query to replace matches mysql_query("UPDATE orig_codes_1a AS a JOIN old_and_new_codes_1a AS b ON concat(a.orig_code_1, a.orig_code_2) = concat(b.old_code_1, b.old_code_2) SET a.orig_code_1 = b.new_code_1, a.orig_code_2 = b.new_code_2") or die(mysql_error()); // END :: Query to replace matches In this query I count ALL records selection: // START :: Create query to be displayed as final results of original codes table. $result = mysql_query("SELECT * FROM orig_codes_1a") or die(mysql_error()); I want to display a count on this part of the query: ....concat(a.orig_code_1, a.orig_code_2) = concat(b.old_code_1, b.old_code_2).... so my database has a page number next to each field. What I need to know how to do is make it so that the paging number, ie being able to select the page, if greater than one, will display 1-whatever the highest page number is. does this make sense? any help is appreciated. I see several great PHP/MySQL paging systems on google, but how can I make a paging system when I'm just showing all images in a directory, not showing all images from a database? I have no idea how I could convert one of those mysql systems to work for my needs. Here is my code: <?php $columns = "4"; $count = "0"; echo '<div style="overflow:auto; width:500px; height:266px;"><table cellpadding="0" cellspacing="10">'; if ($handle = opendir('.')) { while (false !== ($image = readdir($handle))) { if ($image != "." && $image != ".." && $image != "index.php") { if (strlen($image) > 11) { $short = substr($image,0,11); echo '<td align="center"><a href="'.$image.'" title="'.$image.'"><img src="'.$image.'" width="100" height="100"><br><div style="overflow:auto; width:100px;">'.$short.'...</div></a></td>'; } else { echo '<td align="center"><a href="'.$image.'" title="'.$image.'"><img src="'.$image.'" width="100" height="100"><br><div style="overflow:auto; width:100px;">'.$image.'</div></a></td>'; } $count++; if ($count == 4) { echo "</tr><tr>"; $count = 0; } } } closedir($handle); } echo "</table></div>"; ?> This code shows all images in a directory, 4 per row. I'd really appreciate some help with adding a paging feature to this. Thank you so much for the help! Hi Everyone, I need help in paging, i have a form with a lot of text boxes and drop down boxes, i need to use paging "Next..1..2..3", Please someone help me with it, i tried some codes but didn't work out. Thanks RAM Hello, everyone. I am having some trouble figuring this out. I am trying to create a paging bar(so to speak) to display results by page number. Trying to get the paging bar to go as follows... Requested Page The resulting paging bar Page 1 1 2 3 4 5 Page 2 1 2 3 4 5 Page 3 1 2 3 4 5 Page 4 1 2 3 4 5 Page 5 4 5 6 7 8 Page 6 4 5 6 7 8 Page 7 4 5 6 7 8 Page 8 7 8 9 10 11 ...... This is what I have right now that I am trying to get to work. I have changed this so many times and been working on it for 2 days. I think I'm just confusing my self. This can't be that hard.. Code: [Select] <?php echo '<html>'; //---these values changed based on query---- $Page=$_GET["page"]; //the page number requested $AvailablePages=5; //number of pages available after the page requested //---calculations--- $StartPage=round($Page/5)*5; $EndPage=ceil($StartPage/5)*5 ; //the last page number to be displayed in paging if($StartPage<5) {$StartPage=1;} //just looking at variables echo 'page is: ' . $Page . '<br>'; echo '<br>Starting @: ' . $StartPage; echo '<br>Ending @: ' . $EndPage . '<br>'; //--create the paging bar-- $PagingBar=''; while($StartPage<=$EndPage) { if($Page==$StartPage) { $PagingBar=$PagingBar . $StartPage . ''; } else { $PagingBar=$PagingBar . ' <a href="test.php?page=' . $StartPage . '">' . $StartPage . '</a> '; } $StartPage++; } //---show the paging bar-- echo $PagingBar; echo '</html>'; ?> Dear all, I have code for paging The problem is, one of them do not work properly This is OK http://www.amec-berca.co.id/abi/index.php?action=past-projects This is not OK http://www.parnaraya.net/beta/index.php?link=news My question: Is there any issues about PHP/Apache version? or something else? I used this script very often, and no problem so far except this time FYI, the host server using Virtualmin version 3.89 Thanks Hello everybody,

$cat_name get the data submited from othe .php page see line 77

Hello everyone! I'm completely new to PHP and Databases. I've managed to do some nice work by reading, but now I've encountered a problem I can't solve. I made a site with trailers and got tierd of adding them manually. So I created a form which sends the trailer info to my database. There's now trailers in specific organized genres. But the list is beginning to get really big so I wanted to show just 10 trailers per page. And so I found out I could use a paging system which I ALMOST got working. Just one last thing that needs to be fixed and that is when I click on next page "http://www.xxxxxxxx.com/test.php&page=2" it doesn't show the content. While "http://www.xxxxxxxx.com/test.php" does. So I just need that next button to work, I don't know if theres something missing or what it is... Note: I'm new to all this so please excuse my very very bad coding. Here is my code: test.php <link rel="stylesheet" type="text/css" media="all" href="http://www.xxxxxxxxxxxxx.n.nu/createdfiles/trailers/style-twentyten.css" /> <link rel="stylesheet" type="text/css" media="all" href="http://www.xxxxxxxxxxxxx.com/paginate.css" /> <?php $rpp = 10; // results per page $adjacents = 4; $page = intval($_GET["page"]); if(!$page) $page = 1; $reload = $_SERVER['PHP_SELF']; // connect to your DB: $link_id = mysql_connect("server","username","my password"); mysql_select_db("database"); // select appropriate results from DB: $sql = "SELECT * FROM blablabla WHERE Genre LIKE '%Drama%' ORDER BY `blablabla`.`sort` DESC LIMIT 0, 9999"; $result = mysql_query($sql, $link_id); // count total number of appropriate listings: $tcount = mysql_num_rows($result); // count number of pages: $tpages = ($tcount) ? ceil($tcount/$rpp) : 1; // total pages, last page number $count = 0; $i = ($page-1)*$rpp; while(($count<$rpp) && ($i<$tcount)) { mysql_data_seek($result,$i); $query = mysql_fetch_array($result); // output each row: echo "<br />--------------------------------------------------------------------------------------------------------<br /><br />"; ?><strong> <img src=" <?php echo $query['Poster'];?>" /><?php echo "<br /> <br />"; ////////////////////////////// //SHOW TITLE, YEAR AND GENRE// ////////////////////////////// echo "<H1>"; echo $query['Title']; echo "<br /> <br />"; echo "</h1>"; ?></strong> <?php echo "<H2>"; echo $query['Year']; echo "</H2>"; echo "<br />"; echo "<H3>"; echo $query['Genre']; echo "</H3>"; ?> <a href=" <?php ////////////////////////////// //SHOW IMDB, ACTORS AND PLOT// ////////////////////////////// echo $query['IMDB']; ?> " target="_self">Link to IMDb</a> <?php echo "<br /> <br />"; echo "<H2>Stars:</H2>"; echo "<br />"; echo "<H3>"; echo $query['Actors']; echo "</H3>"; echo "<br />"; echo "<H2>Plot:</H2>"; echo "<br />"; echo "<H3>"; echo $query['Plot']; echo "</H3>"; echo "<br /> <br />"; echo "<H2>"; //////////////// //SHOW TRAILER// //////////////// ?> <div id="<?php echo $query['ID'];?>" style="display: none;"> <?php echo $query['Youtube']; echo "</div>"; ?> <a href="javascript:ReverseDisplay('<?php echo $query['ID'];?>')">Click to show/hide trailer.</a> <?php echo "</H2>"; echo "<br /> <br />"; $i++; $count++; } // call pagination function: include("paginate_one.php"); echo paginate_one($reload, $page, $tpages); ?> <?php //////////////////////////////// //SCRIPT FOR SHOW/HIDE TRAILER// //////////////////////////////// ?> <script type="text/javascript" language="JavaScript"><!-- function HideContent(d) { document.getElementById(d).style.display = "none"; } function ShowContent(d) { document.getElementById(d).style.display = "block"; } function ReverseDisplay(d) { if(document.getElementById(d).style.display == "none") { document.getElementById(d).style.display = "block"; } else { document.getElementById(d).style.display = "none"; } } //--></script> paginate_one.php <?php /************************************************************************* php easy :: pagination scripts set - Version One ========================================================================== Author: php easy code, www.phpeasycode.com Web Site: http://www.phpeasycode.com Contact: webmaster@phpeasycode.com *************************************************************************/ function paginate_one($reload, $page, $tpages) { $firstlabel = "First"; $prevlabel = "Prev"; $nextlabel = "Next"; $lastlabel = "Last"; $out = "<div class=\"pagin\">\n"; // first if($page>1) { $out.= "<a href=\"" . $reload .

Really nice forum this! /kvickan 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.

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. I have a list generated from an array by foreach as Code: [Select] foreach ($list_array as $item) { echo "$item<br />"; } This is a long list, how can I separate the list to different pages? I mean the simplest way to do so I'm very new to this and really could use some help. I've got a Web app that has one form that collects data from the user and puts it into a mysql database and has another form that allows the user to select critiera to find records in the database and display them on the page. All this is working just fine, but now that my database is getting more data in it, I want to add functionality to display 10 records on a page with results page navigation links so the user can move forward and backward in the results set. This part is not working and I've put in echo statements to figure out what the code is doing. The problem I'm having is that when the selection critiera pulls more than 10 records from the database, the first page of results is correct per the selection criteria entered by the user on the select form. When the 'next' link is selected to review the second page of results, the query is executed again. But this time the form variables have been reset and the results now contains the entire contents of the db. The start record is set to look at the 11th instance of the results set, so the second page starts with the 11th record in the database instead of the 11th record in the original results set. The original select statement is built by determining which criteria is selected using $_POST against each form variable. How can I retain the form variables or the original select statement so the second execution of the select statement results in the same results set as the first? The other option that may be better is to retain the original results set and avoid re-executing the select statement altogether. But I don't know how to do that either. Any suggestions, code samples or adivice is much appreciated! I am have a query with a limit of 3 i want it to echo the first two in one li class and the 3 in another li class. This is what i have, but i know the logic is not right, but i cant figure it out Code: [Select] </div> <?php echo "<ul class='services-list'>"; //echo "<li class='bubble'>"; $i = 1; foreach ($rows_class as $record_class ){ ?> <li class="bubble"><a href="viewclass.php?class_id=<?php echo base64_encode($record_class[class_id]) ?>" /><h6 class="title"><img src="./images/services/picture-services.png" class="picture" alt="logo" /><? echo $record_class[class_title]; ?></h6></a><p><?php $string = $record_class['description']; echo substr(strip_tags($string), 0, 200); ?></p> <?php if( $i % 2 === 0 && $record_class !== end($rows_class) ) { echo "</li>\n<li class='bubble last'>\n";?> <?php } elseif ( $record_class === end($rows_class) ) { echo "</li>\n "; } $i++; } ?> </ul> Hi All I am using the below code to display users registered on my site: Code: [Select] <div class="profilbox" id="apDiv11"><div></div> <div align="center">Registered Users</div> <div class="text_area"><?php //to display image from source - registerd users $dir = "profpics"; echo '<table>'; $result = mysql_query("SELECT * FROM users order by id"); while ($row = mysql_fetch_assoc($result)) { echo "<tr><td><img src=\"$dir/{$row['prof_pic']}\" width='40' height='40'>{$row['username']}</td></tr>"; } //close out table echo '</table>'; ?></div> </div> Could anybody tell me how i can limit this to 3 random results? I then plan adding a link to 'see all' I am really not sure if this is a problem with me (probably is), php or mysql. I have a calendar that I am adding events to. If I want to edit only the date I can but only once after I make this update I am out. If I attempt to update the time or event title the database is never updated and I am no longer able to update the date. here is the controller for the save. Code: [Select] <?php function eventsave() { $details = $_POST; $this->load->model('eventsmodel'); $this->eventsmodel->eventsave($details,'', TRUE); redirect('/admin/events', 'location'); } ?> I have turned off the redirect to see if I was getting any errors and they seem to be non existent. Here is the model that is used to create a new entry and update a record. Code: [Select] <?php function eventsave($event) { $startdate = explode('-', $event['startdate']); $start = mktime($event['starthour'], $event['startmin'], 0, $startdate['0'], $startdate['1'], $startdate['2']); $end = mktime($event['endhour'], $event['endmin'], 0, $startdate['0'], $startdate['1'], $startdate['2']); $name = $event['name']; if (isset($event['id'])) { // if is true then this is an update not a new event $data = array( 'name' => $name, 'start' => $start, 'end' => $end ); $this->db->where('id', $id); $this->db->update('events', $data); }else{ $this->db->set('name', $name); $this->db->set('start', $start); $this->db->set('end', $end); $this->db->insert('events'); } } ?> I am using code igniter if that helps and the information being submitted by the form looks good. This is the submitted update array and the new event array is just missing the "id" Code: [Select] Array ( [name] => test [startdate] => 05-14-2011 [starthour] => 1 [startmin] => 0 [endhour] => 1 [endmin] => 0 [id] => 54 [saveevent] => save ) Any suggestions would be appreciated. Thank you. Is there a php method/function that can count how many records in a table have the same id. For example you have two tables relating to one another there for there is reason for a coloum to have the same id as another. again my tables are movies| ID(PK) - Titles - Category(FK) - URL 0 Name 1 www.xyz.com categories| ID(PK) - Category 1 Comedy say i create a query SELECT * FROM movies WHERE Category="1" and it gave me all the movies from my table that is in the comedy category which should look like this: ID - Title - Category - URL 0 Name Comedy www.xyz 1 xyz Comedy www.abc etc.. How can i add a drop down menu beside each movie listed in that result that would let me change the category for it and save it ? like this, ID - Title - Category - URL 0 Name Comedy www.xyz [Dropdown] 1 xyz Comedy www.abc [Dropdown] [Save Button] being a newbie im going to guess that i will need a INSERT in here somewhere and not really sure how i would write my result echos. i have been trying all kinds of "update records" forms and cant get them right so i figured it may be easier to just try and create my own. if i could get some example or if you have more simple suggestions |
