How to delete files from server

Hi,

I have a form where people can upload images to the server and it's working fine, I made another form that lets them change the image, and that works fine also, the problem is, how do I delete the old image on the server?

I tried adding this code into a custom code event:

if($fullimgpath!=''){
 unlink ($fullimgpath);
}

but it doesn't work, so I tried putting any type of code in an event, like a simple echo, but I get no response, I tried both controller and view, ad well as different places in the event order, but still no response, so how do I add a custom event? Am I missing something?

PS: the above code works elsewhere on the site, in an article, and the $fullimgpath also works because in the form I use it to display the old image to the user.

Hi mankind1023,

Are you adding PHP tags round your code?

<?php
if($fullimgpath!=''){
unlink ($fullimgpath);
}
?>

I have tried with and without PHP tags, and in different areas of the form.

PS: is there a native way to do this? I'm having users upload a new image to replace the older one but that simply changes the db info, the file is left.

Hi mankind1023,

There's been a thread on this before if you hunt around.

When the form is submitted you need to check if there is a new file, if there is look up the value of the old one; then build a corresponding path and delete the old file (preferably after checking that the new one has uploaded correctly).
