Store Javascript values in an array

Question

I have this javascript code:

var allVals = [];
$('#c_b :checked').each(function() {
   allVals.push($(this).val());
});
alert(allVals + "is checked!");

The code above, will list all the checked values from checkboxes like this: value,value,value

How can I, when submitting my form, store those values in a PHP array, so I can use them?

When you submit a form, if a box is not checked it's value won't be sent. So you really don't need that js code above. Maybe I misunderstood your question? — Brian Glaz

@Brian: That's a non sequitur; the JS code above doesn't do anything about sending anything. — Lightness Races in Orbit

Name all your checkboxes "c_b[]".

The values of those that are checked will then be accessible in the target PHP script as the array $_POST['c_b'] (or $_GET['c_b']).

This is covered fairly well in the relevant manual page, and the manual's FAQ (oh, the irony!).

You can use array's join method to get all the array values as a combined string and then pass it along with the form while submitting it as a hidden field. At the Php side you can split this string and then convert it into an array.

var strAllVals = allVals.join(',');

A hilarious way to send "arrays" to a form target!

Make all your checkboxes name to 1 name.

Then PHP will have the values in an array.

Btw if you re using jquery AJAX you could use serializeArray()
