Question

I am using a simple php form I found here http://www.1stwebdesigner.com/tutorials/custom-php-contact-forms/comment-page-2/#comments

But I am having few issues with it. When clicking the submit button I want to be able to stay on my website instead of being redirected on mail.php and just print/echo the sent message on my website instead.

Also I want to make the fields have requirements, like not being empty which I know how to do in php but I must first solve the redirect issue.

Answer 1

What you need is $.ajax from jQuery. This will send a POST request without reloading the page.

Lets say your button is called myButton then for the onClick() event you would call the function

$.ajax({
  type: "POST",
  url: "some.php",
  data: { name: "John", location: "Boston" }
}).success(function( msg ) {
  alert( "Data Saved: " + msg );
});

In your some.php you would then just use $_POST['name'] and $_POST['location'] to retrieve the information.

Edit

Suppose you had an input field. You can retrieve information from such a field via jQuery as well. You can just then send the information from the input field via ajax to you php script

$('#yourInputField').val();

where yourInputField is the ID of the input field. With this you can get this information to the script. If you have multiple elements in a form you might want to look at the function serialize(). Does the same thing in principle, just compresses all the information into a JSON string.
