Q:

Pause form from submitting with javascript

I am trying to do a submit form with photos. After the user loads the photos he presses the submit button, I want the form to pause for 10 seconds, animate a progress bar for those 10 seconds and then submit the form, can you guys say what I did wrong, it doesn't seem to submit the form after 10 seconds. 
Here is the code:
HTML:
<form action="uploadpic.php" method="post" id="upload_form">
<input type="text" name="title" id="title">
<p id="title_p">Title</p>

<hr />

<input type="text" name="theme" id="picture_theme" size="40"/>
<p id="theme">Picture Theme<img src="../simages/info.gif" id="info" width="12" height="12" style="margin-left:10px;"></p>
<hr />

<div class="custom-upload">
    <input type="file" name="picture" id="true_pic" />
    <div class="fake-file">
        <input disabled="disabled" >
    </div>
</div>
<p id="upload_pic">Upload picture</p>​

<input type="submit" name="submit" id="submit" value="Upload" />
</form>

JAVASCRIPT:
form = document.getElementById("upload_form");
    size=1;
    form.onsubmit = function()
    {
        if (size < 10)
        {
            setTimeout(delayedSubmit,1000); 
        }
        return false;
    }
    function delayedSubmit() {
        size++;
            if (size<5)
            {
                setTimeout(delayedSubmit,1000);
                alert("Counting "+size);    
            }
            else
            {
                alert("Form submitted");
                form.submit();
            }
    }

PHP : 
<?php

if ($_POST['submit'])
{
    $title = $_POST['title'];
    $theme = $_POST['picture_theme'];
    echo $title," ",$theme; 
}

 ?>

I can tell that the form won't submit anything by the fact that the php variables won't show anything, and then page doesn't load.

A:

When a form has a button with the name and/or id "submit", it won't work anymore (my old post was wrong).
So what you need to do is to change the name/id of the button:
<input type="submit" name="submit-button" id="submit-button" value="Upload" />

Remember: You need to change your PHP, too:
if ($_POST['submit'])
{
    $title = $_POST['title'];
    $theme = $_POST['picture_theme'];
    echo $title," ",$theme; 
}

to 
if ($_POST['submit-button'])
{
    $title = $_POST['title'];
    $theme = $_POST['picture_theme'];
    echo $title," ",$theme; 
}
