Does that help PHP's standard form parsing system (which populates $_POST) can't handle multiple bits of form data with the same name (unless that name ends with the characters []).
Change the name of the submit button.
code :

Share : facebook icon twitter icon

This might help you If you have a select with name = enquiry_source and then you ad an input with the same name only one element is posted to the server, in your case the input field (only the latter element is posted) so you should give the field a different name
code :
        var field_to_append = '<div id="form-field-enquiry_source_other" class="form-field float-left">'+
            '<label>Other<span class="required"></span></label>'+
            '<input name="enquiry_source_other" id="form-field-input-enquiry_source_other" />'+

To fix this issue an Idea, you need to store it in session. it seems you get $_POST['user'] from previous page/request. variable $_POST only used for passing variable between page, It will not exist anymore if you reload the page.
do it like:
code :
$user = $_SESSION['user'] = array_filter(array_map('array_filter', $_POST['user']));

seems to work fine The value of $_POST['inputCount'] is being assigned to your session variable regardless of how the page is loaded.
In other words, when you post back using the checkout button, rather than pulling the value of inputCount from the session, you're overwriting the value based on the current $_POST['inputCount'], and then reading that from the session (which is redundant).
code :


//check if the form has been submitted
    $inputCount = mysql_real_escape_string($_POST['inputCount']);
    $_SESSION['InputCount'] = $inputCount;   //it is ok at the begining
} else {
    $iteration = $_SESSION['InputCount'];
    var_dump ($iteration);

    $userID = $_SESSION['UserID'];

should help you out So the approach I ended up using was to look through $_POST for arrays and then merge them. (Obviously, this only works if you know that the only arrays in $_POST are of the type you need…). This is, roughly, my PHP:
code :
    $firstElem = true;
    foreach ($_POST as $element){           
        if( is_array($element) ){
                $firstElem = false;
                $members = $element;
                $members = array_merge($members, $element);

With these it helps Because when you don't select a radio input, no data is sent to the server. As shown in the MDN:
