Question

I am very new to ajax and jquery, but I came across a code on the web which I am manipulating to suit my needs.

The only problem is that I want to be able to respond to the ajax from PHP.

This ajax POSTS to a php page (email.php).

How can I make the email.php reply back if the message is sent or if message-limit is exceeded (I limit the nr of messages sent per each user)?

In other words, I want ajax to take a 1 or 0 from the php code, and for example:

  if(response==1){ alert("message sent"); } else { alert("Limit exceeded"); }

Here is the last part of the code: (If you need the full code just let me know)

var data_string = $('form#ajax_form').serialize();

$.ajax({
    type:       "POST",
    url:        "email.php",
    data:       data_string,
    success:    function() {

    $('form#ajax_form').slideUp('slow').before('');
    $('#success').html('<h3>Success</h3>Your email is has been sent.');
    }//end success function
}) //end ajax call

 return false;

 })

Thanks

You must pass an argument to your “success” function.

success: function(data)
{
    if(data == '1')
    {
        $('form#ajax_form').slideUp('slow').before('');
        $('#success').html('<h3>Success</h3>Your email is has been sent.');
    }
}

And in your php file, you should just echo the response you need

if(mail())
{
    echo '1';
}
else
{
    echo '0';
}
