Problem with HTML form and check boxes

[leachus2002]

Hi Everyone,

 

I am having problems when submitting a form that has check boxes within it (post.php). All the check boxes have a name and a checked value of 1 - the receiving page (for example submit.php) has the variables defined:

$tickbox1 = $_POST['tickbox1'];

 

The problem I am finding is that if the box isnt checked - I get an "index is not defined" error. I would suppose because there is no value.

 

I have tried this before and it has worked, however that was on Apache and this is on IIS.

 

Is there a work around?

 

Thanks

Matt

$tickbox1 = array_key_exists('tickbox1', $_POST) ? 1 : 0;

 

This basically checks to see if the 'tickbox1' key index has been set within the $_POST array. If it has, then set $tickbox1 to 1 (which it would be anyway), otherwise set it to zero if it hasn't been set.
