Wordpress AJAX sending email

问题:

I'm trying to corporate sending email before submitted the form in wordpress page. I'm able to do the AJAX part and send email successfully. However, the email is not 100% delivered. I wonder why?

This is the code

    var data = {};
    data.donorEmail = $("#email").val();
    data.action = "mail_action";
    $("#donorSubmit").click(function(e){
        $.post('http://www.myurl.com/wp-admin/admin-ajax.php',data, onSuccess);
    });

    function onSuccess(results)
    {
        if( results == "00")
            document.forms['donorForm'].submit() // After the email is sent then submit the form to another website. 
    }

And this is the code in functions.php

add_action('wp_ajax_mail_action', 'sending_mail');
add_action('wp_ajax_nopriv_mail_action', 'sending_mail');

function sending_mail(){
    if(isset($_POST['email']))
    {
        $to = "[e-mail]";
        $subject = "Donation";
        $message = $_POST['email']; 

        if(mail($to, $subject, $message))
        {
            echo "0";
        }
    }
}

With this code I receive the email all the time. However, the content of the email which should be the email of user doesn't come with the email all the time. Sometime it's just a blank content.

回答1:

As you see you make:

vardata = {'donorEmail':$('#email').val(),'action':'mail_action' };

but in your php file you request the $_POST['email'] instead of $_POST['donorEmail'];

try calling $_POST['donorEmail'];
