Checking radio buttons

[dweb]

Hi all

 

I have a simple HTML form, but have around 250 radio buttons, which are all needed.

 

All the radio buttons have different "name" attributes.

 

How can I run a check to make sure at least one of the radio buttons has been selected? Is this possible without passing the "name" attribute?

 

thanks

How are you generating your form? You can always create an array of the names. Then loop through and check for them.

$radio_array=array("radio1","radio2","etc");
$selected=False;  
foreach($radio_array as $radio) { 
   if(isset($_REQUEST[$radio] && $_REQUEST['radio'])) { $selected=True; }
}

if($selected) { 
   // do whatever you need to do here.
}
