    Man, you need to do questions with a bit more sense O.o

    So, are you trying to make an AJAX request to your php “file” when the submit button is pressed?

    If yes, follow these steps:

    1. Add a listener to the submit event for you form $(form).submit(ajaxSubmit) when ajaxSubmit is a function that will receive an event as parameter

    2. In ajaxSubmit will be some steps:

      • Make sure that the default event (form submit) will not happens event.preventDefault()
      • If you need, validate the form fields.
      • Serialize your fields and call $.ajax with your parameters and handling a success function

    3. The ajax success function, get the result and write it into some element on form page.

    So, see an example of ajax form submit and handling JSON response
