Question

I have made a method which will delete a file.
first i echo the url to this file.
like this

echo "<a href='$fulr'>$filename</a>";

now basicaly i want to call the function deletefile($file);
how can i do it like this

echo "<a onclick='$this->deletefile($filename)' href='$fulr'>$filename</a>";

is that even posible?

Or how can i implement something similiar inside the php code?

You seem to have the wrong idea about browser/server communication. You need to either do:

<?php
...
printf("<form name=\"delfilefrm\" action=\"delfile.php\" method=\"POST\">
        <input type=\"hidden\" name=\"delfile\" value=\"%s\" />
        <input type=\"submit\" value=\"Delete %s\" />
    </form>", $filename, $filename);
...
?>

In the server, so that the link goes to a script on the server, or use JavaScript. I would recommend using jQuery’s post() function or a similar AJAX function:

$.post("delfile.php", { file: \"$filename\" } );

Remember: security, security, security … then graceful degradation
