Contact Form - jQuery - PHP


I have 2 questions about the form functionality.

  1. I'm creating several forms for a site. In the jQuery section there is a PHP file to link to the form we have in the example for "Smells Like Bakin'". I've used all the code there as an example to create and validate my own forms but when I slick on "Submit" the browser just shows me the .php file. What do I have to modify in the .php file or in the jQuery script so when I click on "Submit" it just refreshes the current page of the site?

  2. One of the forms is in the footer and I'm creating the site from scratch with HTML - CSS and jQuery when needed. In the contact page, for example, I'll have 2 forms that I need to validate: the contact form, and the field in the footer for the user to enter his/her email address. Using the jQuery script once with the same class for both email fields would be ok or should I use different IDs for each one and repeat the email validation in jQuery?

In order to achieve this all you need to do is incorporate the PHP processing inside the page that you have the form. You would use something like this...

    if(isset($_POST['submit'])) {
<!DOCTYPE html>
    <title>Your Form</title>
    <form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">>
        <input name="something" type="text">
        <input name="something_else" type="text">
        <button type="submit" name="submit">Submit</button>

As far as your second question, you could use the same class for your validations. You are only able to use unique id's for an element within each page, so if you have a lot of email validations, you would have to repeat the script multiple times. It isn't best practice to repeat code, so I would just use a single class for all of them.

No problem.
