Re: best way to handle required form fields

For easy form validation, including the red highlighting, maybe check out the qForms library - it's free and very powerful. www.pengoworks.com Cheers Rudi. Dan Anderson wrote:

You could do a check with Javascript to make sure the required fields were filled out and had a valid value to them. Since PHP is completely server side, you would have to check after the page had been submitted. Let's say you have a text field named "foo", ie. <INPUT TYPE=TEXT NAME="foo"> You could use: <?php if ($_POST['foo']) { do_something(); } else { error(); } ?> This is because like many programming languages 0 is false and everything else is true. Form values that are not submitted are equal to NULL -- i.e. false. You could use as many OR statements as necessary to check that everything was submitted. -Dan On Tue, 2003-05-13 at 20:20, daniel@electroteque.org wrote:

hi there i was wondering what would be the most ideal way to handle required form fields say if they were empty and are required , should i do a check and send an error and return to the page with the required fields in red or would a javascript alert box (ugly) be ok ? reason being my prefered way would be sending an error although with my previous issue with custom error handlers might be tedious :|
