function()'s

[Anon]

Hi,

I have a question about functions.
Let's just say this is my code:

............

<?
function delete_file($file) {
$delete = @unlink($file);
$message = $delete ? "file deleted" : "file could not be deleted";

echo $message;
}
?>

............

And then on my normal page I want to create a HREF link that calls the function delete_file(). But how do I do that?

By the way, I don't want to create a new file which can be linked to!

THANKZ

You'll need to have a file to link to to link to the file. Obviously. It doesn't need to be different to the page with the link on it, though.

If the page is called, say, "killfile.php", you can have a link there saying

<a href="killfile.php?name=file%2Etxt">Kill file.txt</a>

And in killfile.php, have the code

<?php
if(isset($HTTP_GET_VARIABLES['name']) and ($HTTP_GET_VARIABLES['name']!=''))
{ deletefile($HTTP_GET_VARIABLES['name']);
}
?>

But the whole idea looks awful dangerous as you describe it.
