RE: [PHP] how to create multiple selects within php

i've decided to punt... and do something similar to what i had initially created, which implements basically what you have below... the user will just have to be satisfied with seeing the 1st item that's a default/dummy item... thanks... -bruce -----Original Message----- From: Silvio Porcellana [mailto:sporc@tin.it] Sent: Monday, October 18, 2004 7:44 AM To: php-general@lists.php.net Subject: Re: [PHP] how to create multiple selects within php You can do something like this: <HTML> <select name='foo'> <option value=''> - - choose one - -</option> <option value='1'>fff</option> <option value='2'>aaa</option> ..... </select> </HTML> and then in your PHP: <?php if ($_POST['foo'] != '') { # do something } else { # Ops, user didn't choose a valure from the 'foo' select!!! } ?> Anyway, you can catch this only *after* the form is submitted: in case you want to block the user from submitting the form if the 'foo' select is empty you need to use some javascript: <script language="JavaScript"> function check_form(form) { if (form.foo.value == '') { alert("C'mon!!!"); return false; } } </script> and in your HTML you need to add something like this to the <form> tag: <HTML> <form action="pippo.php" method="post" onSubmit="return check_form(this);"> <select ...> .... </select> </form> </HTML> Anyway, this has more to do with HTML and JavaScript than PHP...
