Question

Here is what I have going on in my AJAX:

$('#submit-button').click(function(){
    var twit = $('input#twittername').val();
    var email = $('input#email').val();
    if((email == "" || email == "[e-mail]") && (twit == "" || twit == "@twittername")){
        $('p#empty-error').fadeIn();

    return false;
    }

    var datastring = 'email=' + email + '&twit=' + twit;

    if(email != "[e-mail]"){
        $.ajax({
            type: 'POST',
            url: '/path/to/script1.php',
            data: datastring,
            success: function(){
                $('#signup').fadeOut('slow',function(){
                    $('#email-response').fadeIn('slow');
                });
            }
        });

        return false;
    }

    if(twit != "@twittername"){     
        $.ajax({
            type: 'POST',
            url: '/path/to/script2.php',
            data: datastring,
            success: function(){
                $('#signup').fadeOut('slow', function(){
                    $('#email-response').fadeIn('slow');
                });
            }       
        });
    }

    return false;       
});

AJAX is returning the success function. And I can navigate directly to /path/to/script2.php, and it will add an empty record to my database. But for some reason, the PHP is not actually receiving and inserting the AJAX variable.

This was working before, and I’m unsure at what point it stopped. It’s just a bit strange that it is two scripts that were both working, and now neither are.

Script one was written by me, and it inserts a blank record if I navigate straight to it:

<?php

$dbhost = 'host';
$dbuser = 'user';
$dbpass = 'pw';

$con = mysql_connect($dbhost, $dbuser, $dbpass);
if (!$con) {
    die('Could not connect: ' . mysql_error());
}

$dbname = 'databasename';
mysql_select_db($dbname, $con);

$sql = "INSERT IGNORE INTO databasename (column) VALUES ('$_POST['twit']')";

if (!mysql_query($sql)){
    die('Error: ' . mysql_error());
}

echo 'record added successfully';

mysql_close($con);

Script two is modified from MailChimp, and this does nothing if I navigate straight to it, which is expected:

function storeAddress(){

    // Validation
    if(!$_POST['email']){ return "No email address provided"; } 

    if(!preg_match("/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*$/i", $_POST['email'])) {
        return "Email address is invalid"; 
    }

    require_once('MCAPI.class.php');
    // grab an API Key from http://admin.mailchimp.com/account/api/
    $api = new MCAPI('66a7f17d87e96e439f7a2837e2963180-us1');

    // grab your List's Unique Id by going to http://admin.mailchimp.com/lists/
    // Click the "settings" link for the list - the Unique Id is at the bottom of that page. 
    $list_id = "b1ebe7c0ba";

    if($api->listSubscribe($list_id, $_POST['email'], '') === true) {
        // It worked!   
        return 'Success! Check your email to confirm sign up.';
    }else{
        // An error ocurred, return error message   
        return 'Error: ' . $api->errorMessage;
    }

}

// If being called via ajax, autorun the function
if($_POST['email']){ echo storeAddress(); }
?>

Any ideas where I’m going wrong?

Also: I can successfully alert the datastring, if that’s any help.

Needed to delete the top “return false.” A fun way to spend 4 hours.
