post checkbox value

Does anyone no a way to post a unchecked checkbox value?

You would need to put a hidden field in the form before the checkbox and use the same name as the checkbox -

<form method='post' action=''>
<input type='hidden' name='some_name' value='off'>
<input type='checkbox' name='some_name'>
<input type='submit'>
</form>

Why? A checkbox is a boolean - it's either on or it's off. Logically, then, if it is not "checked" it is safe to assume it is "unchecked".

Yea but if it's returned false then teh value wont post and i need the 0 value in order to update a permission record in my table.

So do something like

$check = isset($_POST['checkbox']) ? 1 : 0;

 

If the checkbox is checked it will be "1", if not it will be "0".

Thank you, i used hidden text boxes and used jquery to toggle it's value on a ifChecked event in the end.

What if they have Javascript disabled? Then it will always be "off".

What he said. Using JavaScript is a really poor solution. There are sometimes hurdles when dealing with checkboxes - such as when you have a series of checkboxes to EDIT existing values. But, there are tried and true methods of handling those.
