PHP Form checking if submit has been pressed

I\'ve been going insane the past 3 hours with this issue. I had this completely working.....and it actually still is, but on another page. The only issue is that on a different page it stops working.

I've been going insane the past 3 hours with this issue. I had this completely working.....and it actually still is, but on another page. The only issue is that on a different page it stops working. Here is the basic run down:

User visit page, clicks on button, JavaScript ModalBox opens up.
In the modal box is a form, which the user fills out and hits Send.
The form action is itself so it returns and checks if isset() is true on the submit button.

This is the issue it seems. I got this working on another script, but it's over 5 pages long so here is the small script that I just can't for the life of me get to work:

<?php session_start(); ?>
<html>
<head>
<?php
if (isset($_GET['initForm'])){
    echo 'Complete';
}
?>
</head>

<body>
<?php
    echo '
    <div style="padding:0;margin:0;float:left;height:120px;width:100%;">
    <div align="center" width="50%" style="padding-top:2px;"><img src="images/step1.png"></div>
    <div align="center" width="50%" style="font-face:Arial; font-size:14px;padding-top:4px;">Which package are you interested in?</div>
    <div align="center" width="50%" style="font-face:Arial; font-size:14px;padding-top:6px;">
        <FORM action="test.php" name="initForm" id="initForm" onsubmit="return false;">
            <select name="packageName">
                <option value="Weekend">Weekend - 4 Days/3 Nights</option>
                <option value="Weekday">Weekday - 5 Days/4 Nights</option>
            </select>
</div>
<div align="center" width="50%" style="font-face:Arial; font-size:14px;padding-top:6px;">
        <input Type = "Submit" name="initForm" Value ="Send" onclick="Modalbox.show(\'test.php\', {title: \'Vacation Booking\', width: 600, params:Form.serialize(\'initForm\')}); return false;">
    </FORM>
</div>
</div>';
?>
</body>
</html>

-----FIXED------Solution below:-------

^Th开发者_JS百科e tag had to be placed on the outermost part of the html and now I can access all the elements of the $_Get array, including the submit button. Can anyone explain why this is so picky? I want my 3 hours back. Well at least I'll hopefully never make a mistake like this again.

Forms are usually submitted via POST, but you are checking $_GET. Are you doing an AJAX request and sending the data via GET? If not, you should check:

if (isset($_POST['initForm'])){
    ...

I would do:

if (isset($_GET['initForm']) && $_GET['initForm'] == 'Send'){

Also, I would also probably specify the method in the form element and use POST instead of GET, due to it's intransigence.

Also, why are you outputting echo 'Complete'; in the head block? This is not right. It should be in the body element (which may also be part of the problem).
