$('#button').live('click', function () {
    values_array = [];
    $('.field').each(function () {
        values_array.push = $(this).val();
    });
    $.ajax({
        url: 'page.php',
        data: {
            array_a: values_array
        },
        type: 'POST',

        success: function (data) {
            $('#div').html(data);
        }
    });
});


//page.php
echo $_POST['array_a'] . "<br/>"; //The line break echos, but nothing else

A.) Do I need to iterate through each class with $.each in order to create a proper array, and

B.) Why doesn't php echo it?

Did you tried to put array_a in brackets - data: { "array_a" : values_array }? – Karo May 13 '12 at 11:43
Just tried it. No luck. – Norse May 13 '12 at 11:44
What is the output of print_r($_POST) ? – Karo May 13 '12 at 11:45
Array ( ), as expected – Norse May 13 '12 at 11:47
check out what's the content of values_array after each() with console.log() – Christian Koch May 13 '12 at 11:47

Change:

values_array.push = $(this).val();

to:

values_array.push($(this).val());

That should do the trick :)

.push is a method which you have used like a property try instead 

values_array = [];
   $('.field').each(function() {
      values_array.push($(this).val());
   });
