[N!ck]

this generates a blank page when i access it without a query string even...anyone know why?

<?php
require("../forums/global.php");
if ($action=="upload") {
if ($folderid=="") {
eval("standarderror(\"".gettemplate("error_gallery_nofolder")."\");");
exit;
}
if ($caption=="") {
eval("standarderror(\"".gettemplate("error_gallery_nocaption")."\");");
exit;
}
if ($picfile=="") {
eval("standarderror(\"".gettemplate("error_gallery_nopic")."\");");
exit;
}
$picsize=getimagesize($_FILES['picfile']['tmp_name']);
if ($picsize[0]<200) {
eval("standarderror(\"".gettemplate("error_gallery_pictoosmall")."\");");
exit;
}
if (!eregi("jpeg",$_FILES['picfile']['type'])) {
eval("standarderror(\"".gettemplate("error_gallery_invalidtype")."\");");
exit;
}
$securitycheck=$DB_site->query_first("SELECT * FROM galfolder WHERE galfolderid='$folder'");
if ($securitycheck['userid']!=$bbuserinfo['userid']) exit;
$DB_site->query("INSERT INTO galphoto (galphotoid,galfolderid,caption,dateline) VALUES ('0','$folder','$caption','".time()."'");
$pictureid=$DB_site->insert_id();
if ($picsize[0]>500) {
$aspectratio=$picsize[0]/500;
$newwidth=500;
$newheight=round($aspectratio*$picsize[1]);
} else {
$newwidth=$picsize[0];
$newheight=$picsize[1];
}
$srcimg=imagecreatefromjpeg($_FILES['picfile']['tmp_name']);
$dstimg=imagecreatetruecolor($newwidth,$newheight) ;

You mean you access it just via <script>.php and not via <script>.php?<variables> ?

In the third line, your script checks for $action being equal to "upload", if there is no such variable, that part of the script doesn't get parsed.

[N!ck]

right, just <script>.php. but that should work because it is supposed to output a template if the action is not set to "upload".

[Icheb]

Ok, two things:
Does it work as expected if you call <script>.php?action=upload ?
If so, maybe post the content of the template gallery_upload .

[N!ck]

no, it doesn't work

[Icheb]

I think the problem is the

require("../forums/global.php");

tag. In which folder does the actual script and the global.php reside?

[N!ck]

this script is in:
/public_html/gallery/upload.php

forums are in:
/public_html/forums/

[N!ck]

thanks for your help, but i just remembered that global.php needs editing before use by scripts in other folders

[Link14716]

you, oterwise it won't call functions.php (or any of the other scripts for that matter) correctly.
