Validating Checks, Select & Radios?

[rofl90]

How do you validate checkbox's/select? Do you have to get all values.. but in radios they all have to have the same name so hw do you validate the single one.

 

thanks, charlie

What exactly are you trying to validate when it comes to the radios?  Whether or not they selected one?  You could just select one by default and then have them change it, that way you don't have to validate whether or not it was checked.

use the in_array() function, and have php check that the value of the checkbox or radio button is an acceptable value. Here is an example from a form on my website.

 

$approx_pagesArray = array("1","2","3","4","5","6-10","11-15","16+","dont_know");

if(in_array("{$_POST['approx_pages']}", $approx_pagesArray)){

$approx_pages = urlencode($_POST['approx_pages']);

}

By validating, I meant like for a select, radio, and checks how do you validate eg with text and pw etc u use $user = $_POST['user'];
