Get returned data from PHP to ajax

Question

I have this code

$.ajax({
        type: 'POST',
        url: 'ajaxfunctions.php',
        data: {email: email},
        success: function(data)
        {
            if(data == "true" || data == "false")
            {
                alert("Response")
            }           
            else
            alert("Data: " + data);
        }
    });

with this PHP-Script

if(isset($_POST['email']))
{
$email = $_POST['email'];
$countEmail = $db->getCountEmail($email);
if($countEmail == 1)
    echo "true";
else {
    echo "false";
}
}

The problem is, that it never comes in the alert("Response") case. Always in the other. In the alert window I then got my full index.html content.. What am I doing wrong?

@devShuba在Chrome中监控您的Ajax请求，这是之前的相关文章， 在Chrome中监控请求

Answer 2

maybe the isset($_POST['email']) is returning false, that's why.

can you do a var_dump(isset($_POST['email'])); and check if it evaluates to true? if no, then you have to check if the email is correctly posted using your javascript.
