call to function on a non object?

[darkfreaks]

so how would i fix my code so it does not produce thise error?

 

Line:

<?php

$users = $qls->online_users();?>

[rhodesa]

At that point in the code, $qls has not been declared as an instance of a class. Without knowing more code, it's impossible to tell you how to fix it. Are you working with code you wrote or someone else's?

[Northern Flame]

can we see more code?

[darkfreaks]

Code:

 

<?php
define('QUADODO_IN_SYSTEM', true);
$query=trim(mysql_real_escape_string($query));
include('config.php');
$query = "SELECT * FROM vc_users WHERE username='$u'";
$result = mysql_query($query);

$num=mysql_num_rows($result);

mysql_close();
$i=0;
while ($i < $num) {

$logname = stripslashes($qls->user_info['username']);
$header = mysql_result($result,$i,"header");
$group_id = mysql_result($result,$i,"group_id");
$dpic = mysql_result($result,$i,"dpic");
$privatecomments = mysql_result($result,$i,"privatecomments");
$invisible = mysql_result($result,$i,"invisible");

if ($group_id=="1") {
?>
PLEASE DO NOT bother <?php echo $u; ?> with issues like:<br> 
reporting nudity (unless its a hot girl than report right away)<br>
complaining about other users (This isnt VF)<br>
any other site-related problems (We already know about the bugs)<br>
ALL issues should be sent to:<br>

$qls needs to be defined somewhere as an instance of a class. Do you know what class it is supposed to be an instance of?

[darkfreaks]

it is in the security class so how would i make reference to it?

[Northern Flame]

i dont see where you establish the security class

[darkfreaks]

it must have gotten deleted but in another file there is osmething like

 

<?php


$username = $qls->Security->make_safe($_GET['u']);?>

?>

[rhodesa]

In the file with that line...are there any other calls to set $qls, like

$qls = new ClassName();

 

or does it have some more included files that the page with errors isn't including?

[Northern Flame]

first you need to establish the data inside the class,

heres a good tutorial that helped me learn how to

use classes
