Question

I am having issues loading a jQuery modal window upon submit.

I want a div to load upon submit to thank the user for entering a competition. The div opens fine if I add an a href like: <a href="#dialog" name="modal">click here"</a>

However I can’t seem to make this popup once submit. Am I doing something wrong!?

This is my form php code:

<?php
if($_POST['formSubmit'] == "Submit")
{
    $errorMessage = "";

  if(empty($_POST['formName']))
  {
    $errorMessage .= "<li>You forgot to enter your name</li>";
  }
  if(empty($_POST['formTown']))
  {
    $errorMessage .= "<li>You forgot to enter your town</li>";
  }

    $varName = $_POST['formName'];
    $varTown = $_POST['formTown'];
    $varAge = $_POST['formAge'];
    $varEmail = $_POST['formEmail'];

    $varOne = $_POST['hidden-one'];
    $varTwo = $_POST['hidden-two'];
    $varThree = $_POST['hidden-three'];
    $varFour = $_POST['hidden-four'];
    $varFive = $_POST['hidden-five'];

    if(empty($errorMessage)) 
    {
        $fs = fopen("mydata.csv","a");
        fwrite($fs,$varName . ", " . $varTown . ", " . $varAge . ", " . $varEmail . ", " . $varOne . $varTwo . $varThree . $varFour . $varFive . "\n");
        fclose($fs);

        header("Location: #dialog");
        exit;
    }
}
?>

This is the jquery code:

<script>

$(document).ready(function() {  

    //select all the a tag with name equal to modal
    $('a[name=modal]').click(function(e) {
        //Cancel the link behavior
        e.preventDefault();

        //Get the A tag
        var id = $(this).attr('href');

        //Get the screen height and width
        var maskHeight = $(document).height();
        var maskWidth = $(window).width();

        //Set heigth and width to mask to fill up the whole screen
        $('#mask').css({'width':maskWidth,'height':maskHeight});

        //transition effect     
        $('#mask').fadeIn(1000);    
        $('#mask').fadeTo("slow",0.8);  

        //Get the window height and width
        var winH = $(window).height();
        var winW = $(window).width();

        //Set the popup window to center
        $(id).css('top',  winH/2-$(id).height()/2);
        $(id).css('left', winW/2-$(id).width()/2);

        //transition effect
        $(id).fadeIn(2000); 

    });

    //if close button is clicked
    $('.window .close').click(function (e) {
        //Cancel the link behavior
        e.preventDefault();

        $('#mask').hide();
        $('.window').hide();
    });     

    //if mask is clicked
    $('#mask').click(function () {
        $(this).hide();
        $('.window').hide();
    });         

});

</script>

This is my html:

<form action="enter.php" method="post" target="_self">      
    <input class="submit" type="submit" name="formSubmit" value="Submit">
</form>


<div id="boxes">

<div id="dialog" class="window">
    <p>Modal content here</p>
</div>
</div>

</div>
</div>

<!-- Mask to cover the whole screen -->
<div id="mask"></div>
</div>

It sounds like you may be slightly confused as to what’s happening inbetween your web browser and your web server.

Your web browser is running a client which renders HTML/CSS and executes JavaScript. Your browser will submit a request to the web server which executes the PHP to generate a response.

Once your form has been submitted the request is made to the web server, which generates a response – usually another HTML page. This is where your thank you message should be.
