Store form data in MySQL with jQuery.ajax

Edit: I found the soluton for getting the correct URL. Se the solution in this thread.

Hi, I'm having problems prosessing a form so that I can save it's data in my MySQL database. I'm using Wordpress as CMS.

I've used this example: http://www.ryancoughlin.com/2008/11/04/use-jquery-to-submit-form

I'm pretty sure that the source of my problem, is that I'm using the wrong url: in the javascript. The error message only returns 'undefined' and Firebug reports a page not found 404 error.

So what would be the correct url? Any help would be greatly appreciated.

This is my site structure:

Mywebsite (folder)      
  sl_register.tpl.php   
  includes    (folder)    
  storelocator (folder)
    process_frm_store.php
    frm_store.php
  js (folder)
    myscripts.js

And this is the logic of my site build up:

sl_register.tpl.php:

<?php
/*
  Template Name: SL - Register Store
*/  
  get_header();
  include_once 'includes/storeLocator/frm_store.php';
  get_footer();
?>

frm_store.php:

<form id="store_data_form" class="appnitro"  method="post" action="">
  <input id="store_active" name="store_active" type="hidden" value="pending" />
  <input id="store_name" name="store_name" type="text" value=""/> 
  <input id="store_street1" name="store_street1" type="text" value="" />
  <input id="saveForm" class="submitButton" type="submit" name="save" value="Save" />
</form>

process_frm_store.php:

<?php
  $myDB = new DAL(); 
  $myDB->connect();

  if (isset($_POST['save'])) 
  {
    $formData =  array(
      "name"=> mysql_real_escape_string($_POST['store_name']),
      "street1"=> mysql_real_escape_string($_POST['store_street1']),
      "zipcode"=> mysql_real_escape_string($_POST['store_zipcode']));

    $myDB->addNewStore($formData);
  }
?>

myscripts.js:

jQuery.processForms = function()
{
  jQuery('form#store_data_form').submit(function() 
  {
    var store_name = 'Test store'; //jQuery("input#store_name").val();
    var store_street1 = 'Sesamy street';//Set constant for testing
    var store_zipcode = '0574'; //Set constant for testing
    var dataString = 'name='+ store_name + '&street1=' + store_street1 + '&zipcode=' + store_zipcode;    
    jQuery.ajax(
    {   
      type: "POST",   
      url: "process_frm_store.php",   
      data: dataString,
      error: function(XMLHttpRequest, textStatus, errorThrown) 
      { 
        alert(errorThrown); // Just for debugging
        jQuery('#suggestNewStore div.error').fadeIn(); 
      },
      success: function() 
      {
        alert('It works!');
        jQuery('#suggestNewStore div.success').fadeIn();   
      }   
    });   
    return false;      
  });
}

From stackoverflow

• It it simpler to user the absolute path like http://www.yourwebsite.com/storelocator/process_frm_store.php to be on the safe-side.

  Otherwise the url param of the .ajax method should be storelocator/process_frm_store.php because your ..js file is included and executed in your base path, outside the js or storelocator folders

  Steven : Thanks for your answer Bogdan. I don't think that will work though, since I'm using Wordpress CMS with user friendly URL's. The URL for my page / form is: http://localhost/mysite/store-locator/register-store-label The logical URL is: http://localhost/mysite/sl_register.tpl.php Firebugs reports he following error: POST (url) 404 Not Found Where url is whatever i put in my javascript file.

• You have <?php tags wrapped around your include_once in sl_register.tpl.php when it is already inside of <?php tags ...unless you're doing something that I don't understand this is probably breaking something.

  Steven : Oh sorry... that's just a typo from my cut and paste. In my full code, that line is outside PHP tags. I'll edit and fix this.

• I've currently given up trying to get this to work. I'll get back to this once I've solved some other issues which are related.

  Stuart Branham : Rather than posting this as an answer, it's better for these types of comments to be edits in your question or a comment on your question.

  Steven : I'm marking this as correct answer, since I can't mark my first post. And since I can only comment, and not post, a new answer to my own problem, take a look at my Edit at the top.
