Re: [PHP] Using custom "button" form element instead of standard"submit"?

sure this would work but it'd be VERY inefficient in my application.  It's a
file browser application so i have hundreds of folder icons on a page .. the
'submit' element will pass back the name of the button clicked and it would
be available immediately/directly, which is what i want.  BUT an 'image'
element would require me to loop through ALL buttons doing an 'isset' test
on each one.

* if there is not other data in the form you coudl turn it into an image link and get the value in the $_GET
* else walk through the $_GET vars (each key/value) untill you see a varname that could be what you looked for.

I can't believe html provides no means for using an icon as a submit button.

well it does doesn't it?

by the way .. unrelated question ... why would one want to use
$_REQUEST['foo'] instead of just $foo? doesn't php give you access to form
variables using the latter construct which is much cleaner?

not automatically anymore since PHP 4.10.
and the exact reason was that the old way was NOT clean, see the release notes for PHP 4.10 for the details.
