If checkbox.checked, post variables

Hey.

I have a webform, where I would like to be able to post a couple of hidden form fields if one particular checkbox is checked.

I tried something like this:

<p><label>Adresser:</label><input id="address" type="checkbox" name="pm_street_address" /></p>

<script type="text/javascript">
if (document.forms.pm_street_address.checkbox.checked) {
		<input type="hidden" name="pm_post_num" value="pm_post_num" />
		<input type="hidden" name="pm_post_area" value="pm_post_area" />
}
</script>

Code (markup):

but that didn't work - at least nothing gets posted to the receiving page, it seems, whether the checkbox is checked or not (the "pm_street_adress" gets posted, of course).

So, how would I approach this to get a couple of $_POST-variables from this, if the address-checkbox is checked?

Anyone?

 

You don't have a checkbox value. Assign a value to your checkbox such as value="yes".
Then use something like this:

if ($_POST['pm_street_address'] == 'yes') // If it's checked
{
//Get other variables

}

 

Yeah, I figured out how to achieve my goal a little earlier

You are absolutely right - I was trying to do it in an overcomplicated fashion
