ok im using a php file as way to have an image displayed. i want it to like <img src="http://www.blah.com/blah.php?do=image&id=666">
but it doesnt work. it only works if its just blah.php and nothing after it, is there anyway around this or fix?

heres my code:

PHP Code:

if($do=="image"){
if(empty($a)){
header("Location: $vboptions[bburl]/images/error.gif");
}

Err.. there's not really enough code there to determine much, however, I don't see where you've assigned "$do" to anything, or even "$a" for that matter.

Might wanna start off with:

PHP Code:

if ($_POST['do'] == 'image') 
{ 


And work your way from there.

well someone is linking to this file so it would $_REQUEST['do'] anyways, wouldnt it?

How about posting more of the code? You're leaving us at empty when you specify variables that have no origin.

vBulletin files should always structure around the following syntax:

PHP Code:

<?php

error_reporting(E_ALL & ~E_NOTICE);

define('NO_REGISTER_GLOBALS', 1);
define('THIS_SCRIPT', 'filename');

$phrasegroups = array();

$specialtemplates = array();

$globaltemplates = array(
    'template_1'
);

$actiontemplates = array();

require_once('./global.php');

if ($_REQUEST['do'] == 'something')
{

// do stuff

}

// etc.

?>

heres where it originates from: the $a comes from a link

PHP Code:

<?PHP
error_reporting(E_ALL & ~E_NOTICE);
include('./global.php');
$globaltemplates = array(
'STANDARD_REDIRECT',
'STANDARD_ERROR',
);
$fsettings= $DB_site->query("SELECT * FROM affiliates_settings");
$settings= $DB_site->fetch_array($fsettings);

if($_REQUEST['do']=="image"){
if(empty($_REQUEST['a'])){
header("Location: $vboptions[bburl]/images/error.gif");
}
else{
header("Location: $settings[imagelink]");
}
}
