unset(filename);

 

make sure you navigate to the right directory first to delete. for example,

 

$filename = // Code to get the filename from the database

unset($filename);

 

Simple as that,

You may not have permission to delete the file.  It seems like you're trying to delete from php, and you should be aware that php usually running as least privileges user on most system.

this is the code i made :

 

$foto = $row['foto'];

$filename = dirname(__FILE__).'/../catalogue_images/'.$foto;

unset($filename);

 

but it doesnt affect anything, i think the dirname i made is wrong, can u help me fix it.

 

 

[calabiyau]

$foto = $row['foto'];
$path_to_file = "../catalogue_images/".$foto;
unlink($path_to_file);

 

That should work if permissions are set...just make sure to get the path correct...it is relative to where the running script is located.  So if it is located one level above that then you have ../catalogue_images

if it is a folder within the same directory as the script it is simply "catalogue_images/".$foto

 

Sorry if you already know that stuff, but maybe you don't

PHP won't delete a directory if there are files in it.
