PHP - How Can I Limit The Amount Of Queries Returned?
if i want to display upcoming events and only want to show the top 3?
Similar Tutorials$text = "this is a lot of effing text" what i want to do is limit it to the 10 characters so it gives back $stext = substr($text, 10); <-- this is how i thought it would work echo " $stext"; Hey quick question on my homepage there is a featured content section, which is populated from my DB some of the posts are really long so I would like to limit the amount of text. how can I do this? also is there a way to make sure if does not cut a word in half? thanks Heres what i got... function printLB1 (){ $result = mysql_query("SELECT * FROM leaderboards ORDER BY CollegeFootballPoints DESC"); while ($row = mysql_fetch_object($result)) { $leaderboard[] = $row->Username; $leaderboardPoints[] = $row->CollegeFootballPoints; } $num = mysql_num_rows($reault); //I know from here to ................... needs to be in a var or echo or something. <tr> <td>1.</td> //This will auto increment too like i++ but i cna do that myself! <td>echo $leaderboard;</td> <td>echo $leaderboardPoints;</td> </tr> //Here......................................................... } I need to pull a table row per user. But i want to somehow do it once in a function and then ill echo the function into a table after the php stuff is done. Like i want to pull every a table row per user in the function. then display the function below that way i don't have to write a whole extra query and table row per person. If you understand please help if not please let me know where i can explain more. Thanks 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? When I submit the login form its not returning anything and it was working until I added in the $remember part so I'm wondering why its still not returning TRUE. Code: [Select] /** * Login user on the site. Return TRUE if login is successful * (user exists and activated, password is correct), otherwise FALSE. * * @param string * @param string * @param int * @return bool */ function login($username, $password, $remember) { $this->ci->load->model('kow_auth/users'); $user_data = $this->ci->users->get_user_by_username($username); if ($user_data) { $regenFromPostPW = $this->ci->genfunc->reGenPassHash($password, $user_data->password2); if ($regenFromPostPW == $user_data->password) { $this->ci->session->set_userdata(array( 'xtr' => 'yes', 'user_id' => $user_data->user_id, 'username' => $user_data->username, 'status' => $user_data->users_statuses_id, 'role' => $user_data->users_roles_id )); if ($remember == 1) { $timeTOexpire = time()+(60*60*24*31*2); $this->input->set_cookie('xtrcook', '1', $timeTOexpire); } else { $cookie = trim(get_cookie('xtrcook')); if ($cookie || is_numeric($cookie)) { delete_cookie('xtrcook'); } } $this->clear_login_attempts($user_data->user_id); $this->ci->users->insert_session($this->ci->session->userdata('session_id'), $this->ci->session->userdata('user_id'), $this->ci->genfunc->getRealIpAddr(), $this->ci->genfunc->getUserOS()); return TRUE; } else { $this->increase_login_attempt($user_data->user_id); } } else { return NULL; } } So I am accessing a web service and it returns a bunch of values, I am able to grab and print the first value, but I can't figure out how to print the second value. PHP Code that works Code: [Select] <?php //Web service that works fine $client = new SoapClient("http://www.domain.com/sc001.asmx?WSDL"); $sc001 = $client->$NT(array('var1'=>$var1)); //Grab the value tag and print it from web service call and in this case prints 001 $tag = $sc001->NTResult->results->TaggedText->tag; echo $tag; ?> But how do I get it to print the second tag that equals 120? I've tried this Code: [Select] <?php $tag2 = $sc001->NTResult->taggedResults->tag; ?> and this Code: [Select] <?php $tag2 = $sc001->NTResult->taggedResults->TaggedText->tag; ?> and this Code: [Select] <?php $tag2 = $sc001->NTResult->results->TaggedText->taggedResults->TaggedText->tag; ?> But neither work. The var_dump for is sc001 is: Code: [Select] object(stdClass)#9 (1) { ["NTResult"]=> object(stdClass)#10 (2) { ["count"]=> int(1) ["results"]=> object(stdClass)#11 (1) { ["TaggedText"]=> object(stdClass)#12 (2) { ["tag"]=> string(3) "001" ["taggedResults"]=> object(stdClass)#13 (1) { ["TaggedText"]=> array(27) { [0]=> object(stdClass)#14 (2) { ["tag"]=> string(4) "120" ["textArray"]=> object(stdClass)#15 (1) { ["string"]=> array(2) { [0]=> string(28) "Rocks " [1]=> string(14) "Big Rocks" } } } } } } } } } } } and the XML return from the service is: Code: [Select] <?xml version="1.0" encoding="utf-8" ?> - <TaggedTextArray xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.domain.com/sc001"> <count>1</count> - <results> - <TaggedText> <tag>001</tag> - <taggedResults> - <TaggedText> <tag>120</tag> - <textArray> <string>Rocks</string> <string>Big Rocks</string> </textArray> </TaggedText> Maybe the question is, how do you handle a SOAP returned array? I'm not sure, any help is appreciated. Thanks, sanchez It's been quite a while since I have coded in PHP and I am running into difficulties looping through the returned response from an API. I am pretty comfortable in my PHP skills, but for some reason I keep getting caught up trying to loop through the following... Many of the returns from the API include several more layers of Objects, the example below is about the most simplistic return from the API.
I'm sure I'm just missing something easy and any help or example code simply looping through and echoing each result would be greatly appreciated!! Ideally I would like to be able to loop through both of the scenarios below.
I did a var_dump on the response and here is what I get:
array (size=1)
'Body' =>
object(stdClass)[6]
public 'userContext' =>
object(stdClass)[8]
public 'convCred' =>
object(stdClass)[10]
...
public 'valid' => boolean true
public 'isPasswordExpired' => boolean false
public 'cbId' => int 0083802121
public 'cnId' => int 1000545
public 'locale' => string 'en_US' (length=5)
public 'tncVersion' => int 2
public 'applicationId' => string 'ECFDA1FDBC00270772870CDC1786FFED' (length=32)
public 'cbConvCred' =>
object(stdClass)[9]
...
public 'preferenceInfo' =>
object(stdClass)[7]
...
public 'lastLoginTime' => int 1406729928
public 'loginCount' => int 282
public 'passwordRecovered' => boolean false
public 'emailAddress' => string 'abc@123.com' (length=11)
public 'loginName' => string 'TEST' (length=8)
public 'userId' => int 15932274
public 'userType' =>
object(stdClass)[14]
public 'userTypeId' => int 1
public 'userTypeName' => string 'normal_user' (length=11)
public 'isConfirmed' => boolean false
If I jsonencode and jsondecode the response this is what I get:
object(stdClass)[13]
public 'Body' =>
object(stdClass)[17]
public 'userContext' =>
object(stdClass)[18]
public 'convCred' =>
object(stdClass)[19]
...
public 'valid' => boolean true
public 'isPasswordExpired' => boolean false
public 'cbId' => int 0083802121
public 'cnId' => int 1000545
public 'locale' => string 'en_US' (length=5)
public 'tncVersion' => int 2
public 'applicationId' => string 'ECFDA1FDBC00270772870CDC1786FFED' (length=32)
public 'cbConvCred' =>

Hi I have a couple of phpbb forums on my web space. One is randomly throwing people off and it is getting far worse. I have traced down the issue to the IP address. Phpbb stores the IP address and session id and checks that they match. If not it throws the user out. The session ids seem to be there OK, but the IP addresses aren't. When it causes a problem the IP address seems to be returned as "::" (yes, 2 colons). I have used the following routine to try and obtain a relevant IP address and it to returns "::" Code: [Select] function getRealIpAddr() { if (!empty($_SERVER['HTTP_CLIENT_IP'])) //check ip from share internet { $ip=$_SERVER['HTTP_CLIENT_IP']; } elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) //to check ip is pass from proxy { $ip=$_SERVER['HTTP_X_FORWARDED_FOR']; } else { $ip=$_SERVER['REMOTE_ADDR']; } return $ip; } Any ideas? All the best Keith Hi guys, I am working with an old script at the moment, there is one page which just will not populate the table results. I have tried running multiple debugging commands but the only one it flags is the line displaying Quote last; saying it's not a used function. If I comment out this line, no errors are produced but the results do not enter the table. Can anyone shed some light on this please, I've spent hours and hours and banging my head against a brick wall would probably be more constructive right now. Many thanks indeed for any help or advice. <?php mysql_connect("localhost", "$db_user","$db_upwd") or die ("Error - Could not connect: " . mysql_error()); mysql_select_db("$database"); $query="select host,count(*) from badc_mis_prog group by host"; $result = mysql_query($query) or die ("Error - Query: $query" . mysql_error()); $count=0; $hosts=array(); while ($row = mysql_fetch_array($result, MYSQL_NUM)) { $html_hlname=$row[0]; $html_hlname=preg_replace("/</","<",$html_hlname); $html_hlname=preg_replace("/>/",">",$html_hlname); array_push($hosts, $html_hlname,$row[1],0); $count++; } $query="select host,count(*) from badc_mis_prog where reported=1 group by host"; $result = mysql_query($query) or die ("Error - Query: $query" . mysql_error()); while ($row = mysql_fetch_array($result, MYSQL_NUM)) { $html_hlname=$row[0]; $html_hlname=preg_replace("/</","<",$html_hlname); $html_hlname=preg_replace("/>/",">",$html_hlname); for ($i=0; $i<($count*3); $i+=3) { if ($hosts[$i] == $html_hlname) { $hosts[($i+2)]=$row[1]; last; } } } for ($i=0 ; $i<(($count-1)*3); $i+=3){ for ($j=$i+3 ; $j<($count*3); $j+=3){ if ($hosts[($i+1)] < $hosts[($j+1)]){ $temp=array(); $temp[0]=$hosts[$i]; $temp[1]=$hosts[($i+1)]; $temp[2]=$hosts[($i+2)]; $hosts[$i]=$hosts[$j]; $hosts[($i+1)]=$hosts[($j+1)]; $hosts[($i+2)]=$hosts[($j+2)]; $hosts[$j]=$temp[0]; $hosts[($j+1)]=$temp[1]; $hosts[($j+2)]=$temp[2]; } } } print "<br><br><br><center><table border=\"1\">\n"; print "<tr><td>Host Name</td><td>Hosted</td><td>Reported</td><td>Ratio H/R</td></tr>\n"; for ($i=0; $i<($count*3); $i+=3) { if ($hosts[($i+1)]<15){ break;} printf ("<tr><td> %s </td><td> %d </td><td> %d </td><td>%.1f %%</td></tr>\n",$hosts[$i],$hosts[($i+1)],$hosts[($i+2)],(($hosts[($i+2)]/$hosts[($i+1)])*100)); } print "</table></center>\n"; ?> Hi all, I really need some help getting values from the usps api Well not getting them but using them.

For instance turn that result into a 3 item select box with these options Express Mail - $49.70 Priority Mail - $18.35 Parcel Post - $12.29 Hope that makes sense. Any help appreciated. Need some help finding out why this is returning a null result set:
The below code is giving me a result set of an integer set to "0" (the id), a "word"and "def" both set to NULL. It's failing at my "Error #2" point. var_dumps on $id, $word, and $def all give the null output. Each $category is being shown when I var_dump($category).
I know this shouldn't be the case because when I run this straight in PHPMyAdmin I get a non-null result set.
(Not sure why my indentation is not carrying over to the forum. Sorry about that.)

Edited by HDRebel88, 01 June 2014 - 08:54 PM. Am currently using this code, and actually thinking about it should split the query to an include in order to allow for other database drivers, on the chance we may decide to ditch the old MySQL. But I digress from the question. Code: [Select] include($lib."dbconfig.php"); $q = 'SELECT * FROM file WHERE this = "'.$that'"; $result = mysql_query($q); if (mysql_num_rows($result) > 0) If the query doesn't pick up a row I'm getting this error yo, Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in D:\webpages\*\*\admin.php on line 553 So what would be a better way of testing if the query was successful? Hello,
This is confusing me! - this code is finding 2 rows of data ($nrows is 2), but I'm only getting 1 row of data returned. On the second while loop I'm getting the following error message:
Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in /home/website.com/test.php on line 26
$query ="SELECT * FROM Accounts WHERE (jaaLatitude = '' OR jaaLongitude = '')";
$result=mysql_query($query)
or die ("Connection to database table failed." . mysql_error());
$nrows=mysql_num_rows($result);
$i = 0;
if ($nrows > 0)
{
while($record = mysql_fetch_array($result, MYSQL_BOTH))
{
$jaaIndex = $record[jaaIndex];
$jaaEmail = $record[jaaEmail];
$jaaLocation = $record[jaaLocation];
$jaaLongitude = $record[jaaLongitude];
$jaaLatitude = $record[jaaLatitude];
echo "<br>test jaaEmail is $jaaEmail<br>";
$i = $i + 1;
}
}
As I say the first while loop is working, so I don't see what can be wrong with the qurery (it's not failing).
Thanks for your help,
S
I have a class that I use to do my db queries. I'm starting to work on a new project and purposely put in a query which would fail, thus returning no results, just to make sure the error trapping is working. Here's my code: Code: [Select] function getResults($query) { $results = mysql_query($query) or die (mysql_error() . "\n\nYour request couldn't be procesed.<p>" . $query); $itemcount = count($results); if ($itemcount > 0) { $i=0; while($itemcount > $i) { $i++; $userdata = array('queryresult' => '!success', 'displayName' => mysql_result($results, $i-1, 'displayName'), 'title' => mysql_result($results, $i-1, 'title')); } } else { $userdata = array('queryresult' => '!fail'); } return $userdata; } when I print $itemcount it returns a value of 1, which forces the conditional and an attempt at parsing the results array. However, in my browser I get these error messages: 1 Warning: mysql_result() [function.mysql-result]: Unable to jump to row 0 on MySQL result index 4 in /Library/WebServer/Dev/timesheet/lib/mysqlconnect.php on line 29 Warning: mysql_result() [function.mysql-result]: Unable to jump to row 0 on MySQL result index 4 in /Library/WebServer/Dev/timesheet/lib/mysqlconnect.php on line 29 It seems as if it is telling me that results has both 1 and no items. Am I doing something to cause this? Hello all,
I feel pretty good that I got my AJAX filter working properly. But it still needs some help. Now I am returning the content with Ajax that I want from the search filter of dropdown option (keep in mind there are several options to filter by). But the content returned is often to much to fit on one page - so I need to paginate the successfully returned html from my AJAX call.
Here is where I get stumped. Do I setup a normal page nav outside the AJAX area?
</div><!-- AJAX return container-->
<nav class="pagenav">
<ul id="pag-link">
<li class="old"><?php next_posts_link('« Older Sermons', $sermons_query->max_num_pages) ?></li>
<li class="new"><?php previous_posts_link('Newer Sermons »', $sermons_query->max_num_pages) ?></li>
</ul>
</nav>
IF so, how do I update the links info?
or do I keep the page nav inside the AJAX area but use some custom code to retrieve the proper link? (I tried using the normal wordpress page nav functions in my php function but they provide the url of the page that the php function is on, not the actual page being viewed).
Do I need to make a separate AJAX call to a function that just builds my links? or is there a way to do it with my main call?
Here is my AJAX call:
//Listen for the menu's to change except the main filter_by dropdown
var ids = ['filter_preacher_dropdown', 'filter_sort_by_dropdown', 'filter_per_page_dropdown',
'filter_series_dropdown', 'filter_service_dropdown', 'filter_tag_dropdown', 'filter_book_dropdown', 'filter_year_dropdown'];
$('#' + ids.join(',#')).change(function(e) {
var pt = [ "preacher","series","service" ];
if($.inArray(this.name, pt)!==-1){
var mk = this.name;
var mv = $(this).val();
var ppp = $("#filter_per_page_dropdown").val();
var ob = $("#filter_sort_by_dropdown").val();
var data = {
action: 'filter_sermons',
meta_key: mk,
meta_value: mv,
posts_per_page: ppp
};
$.post(mbsb_ajaxurl, data, function(response) {
$('#sermonlists').fadeOut('slow', function() {
$(this).html(response)
}).fadeIn('slow');
});
}
and here is my php function (slightly paired down for viewing ease):
//ajax for sermons filter
add_action('wp_ajax_filter_sermons', 'check_ajax');
add_action('wp_ajax_nopriv_filter_sermons', 'check_ajax');
function check_ajax() {
global $wpdb, $paged, $max_num_pages;
//check if filter is on post_type
if($_POST['meta_key']){
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$mk = '"'.$_POST['meta_key'].'"';
$mv = intval($_POST['meta_value']);
$ppp = intval($_POST['posts_per_page']);
$offset = ($paged - 1) * $ppp;
$sermons = $wpdb->get_results("SELECT SQL_CALC_FOUND_ROWS sermons.* FROM {$wpdb->prefix}posts AS sermons, {$wpdb->prefix}postmeta WHERE meta_key = {$mk} AND meta_value = {$mv} AND sermons.ID = {$wpdb->prefix}postmeta.post_id LIMIT {$offset}, {$ppp}", OBJECT);
$sql_posts_total = $wpdb->get_var( "SELECT FOUND_ROWS();" );
$max_num_pages = ceil($sql_posts_total / $ppp);
}elseif($_POST['name']){
//another custom query
}elseif ($_POST['book_number']){
//another custom query
}
$posts = get_posts(); // returns posts in an array
if($sermons) {
global $post;
foreach ($sermons as $post){
setup_postdata($post);
//custom query info returned here
}
//Would the Pagination for the AJAXED content go here?
}else{ ?>
<h2 class="center">Not Found</h2>
<p class="center">Sorry, but you are looking for something that isn't here.</p>
<?php
}
die();
}
Have a web page that displays a number of update forms depending on the amout of records that get returned from a mysql query, if query returns 4 records then the page will display 4 identical forms, the trouble i'm having is getting the each of the 4 forms to display a different record as at the moment they all show just first record of query. I have played around with loops but not getting anywhere which may be due to my limited knowledge code for page is below Code: [Select] <?php $numberofrow =mysql_num_rows($Recordset1); for($counter = 1;$counter<=$numberofrow;$counter++){ ?> <label for="hometeam2"></label> <form id="form1" name="form1" method="POST" action="<?php echo $editFormAction; ?>"> <label for="hometeam"></label> <input name="fixid" type="text" id="fixid" value="<?php echo $row_Recordset1['FixtureID']; ?>" /> <input name="hometeam" type="text" id="hometeam2" value="<?php echo $row_Recordset1['hometeamname']; ?>" /> <label for="homescore"></label> <input name="homescore" type="text" id="homescore" value="<?php echo $row_Recordset1['homescore']; ?>" /> <label for="awayscore"></label> <label for="fixid"></label> <input name="awayscore" type="text" id="awayscore" value="<?php echo $row_Recordset1['awayscore']; ?>" /> <label for="awayteam"></label> <input name="awayteam" type="text" id="awayteam" value="<?php echo $row_Recordset1['awayteamname']; ?>" /> <input type="submit" name="update" id="update" value="Submit" /> <input type="hidden" name="MM_update" value="form1" /> Probably a silly question, but say you have a value in a mysql database that (naturally) can be either be blank or have characters in it. If in my PHP I am doing a check to see if that returned field from the database HAS or DOES NOT HAVE a value entered in it, what is the proper way to do it? For example, you could do either of the following below (and I'm sure there are probably 10 other ways to do it as well). Is one of these quicker/more efficient than the other? I know it probably does not matter in the grand scheme of things because it's such a quick check either way, but if one way is more "proper" than the other, please let me know... Code: [Select] if ($mysqlvalue!=="") OR if (strlen($mysqlvalue>0)) OR I was just wondering when you run a mysql query what the easiest way to find out the number of rows returned. Just so I can do a number of results found on a search. Thanks. |
