$_GET returns wrong vars

[Dudditz]

I recently moved a small script from a server with php5.2.4 to one with php5.2.5

and certain areas have stopped working.

After some debugging I went back to square one and set up 2 files as follows:

.htaccess

RewriteEngine On
RewriteRule ^(.+)/(.+)/(.+).png /image.php?type=$1&style=$2&tag=$3

image.php

<?php
echo $_GET['type'];
?>

 

For some reason, the type will add a file extension if there is a file name existing in the directory

threrfore returning the wrong data to my script.

If there is no file by the type it will display properly.

example: if $_GET['type'] is image in the url mydomain.wer/image/some/picture.png

            the $_GET will return image.php instead of image since there exists an image.php file in directory.

 

Its like the server is searching the directory for a file by that name instead of just returning the url part like its supposed to.

Does anyone know why this is happening?

thanks

I am not that a big regexp expert.

Try first to see the phpinfo() difference on these 2 webservers (previous and new one).

Also try

RewriteRule ^(.+)/(.+)/(.+)\.png /image.php?type=$1&style=$2&tag=$3

instead of

RewriteRule ^(.+)/(.+)/(.+).png /image.php?type=$1&style=$2&tag=$3

I'll look into the php differences but the RewriteRule change did not solve the issue.

For now, I have simply renamed the image.php to image1.php and it works

When I echo $_GET['type']; with any name in that url location that has the same name of a file within the directory,

it will echo the filename instead of the $_GET from url.

If I put example in the url, it will echo example until I create an example.ext in which it will then echo example.ext

Driving me nuts but I will rename filenames for temporary measure.

You might want to apply a rewrite condition:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)/(.+)/(.+)\.png /image.php?type=$1&style=$2&tag=$3

Also it may because you're using (.+) which I believe is greedy. What you should do is use character ranges:

 

Full code

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([a-z]+)/([a-z]+)/([a-z]+)\.png$ /image.php?type=$1&style=$2&tag=$3 [NC]
