[SOLVED] Stopping specific strings (.jpg etc)

[RickyF]

Hey,

 

How can i make it so that only if .jpg etc is stopped, as the word jpg etc is being stopped, i tried adding dots before each word in the array, but this made no difference.

 

Thanks

 

  if (eregi("jpg|jpeg|gif|bmp|png", $weburl)) {
  die ("Your website url can not be an image.");
       }

if (preg_match('/\.(jpg|jpeg|gif|bmp|png)$/', $weburl))

 

However, this is quite pointless since any type of content can be delivered using any "file extension".

Hello,

 

The script is actually a plug board im developing, the point of the partiular validation is to stop people from posting the link to their banner in the website url input field, as some people seem to get confused and try putting the image into the web address and vice versa.

 

Thanks for the help.
