我正试图通过WordPress使用wp_mail() 功能，但似乎不起作用。

它正在显示0 在Chrome“网络”响应中，使用

Status Code:200 OK

    // Contact form  Ajax 

    add_action(\'wp_ajax_nopriv_submit_contact_form\', \'submit_contact_form\'); 

    function submit_contact_form(){

        if(isset($_POST[\'email\'])) {

            $email = $_POST[\'email\'];       
            $email_to = "[email protected]";

            $host = "ssl://smtp.gmail.com:465";
            $username = \'[email protected]\';
            $password = \'passpass\';

            $email_subject = "You have a new email from $email via company.com website";
            $message = $_POST[\'text\']; 

            $headers = array (\'From\' => $email, \'To\' => $email_to,\'Subject\' => $email_subject);
            /*$smtp = Mail::factory(\'smtp\',

                \'password\' => $password));*/

            //$mail = $smtp->send($email_to, $headers, $message);

            wp_mail( $email_to, $email_subject, $message );

            /*if (PEAR::isError($mail)) {
              echo($mail->getMessage());
            } else {
              echo("Message successfully sent!\\n");
            }*/
        }
    }





    error_reporting(E_ALL);
    ini_set("display_errors", 1);

编辑：

这是ajax部分：

// Send button for the "contact form".
$(\'#sendBtn\').click(function(){
    //get info 
    var fullname = $("#fullname").val();
    var email = $("#email").val();
    var text = $("#text").val();

    //send info to php 
    $.ajax({
        beforeSend: function() {
            if ( IsEmail(email) == false) {
                $(\'#aboutUnsuccess\').show("slow");
                $(\'.form_content\').hide("slow");
            }
        },
        url: document.location.protocol+\'//\'+document.location.host+\'/wp-admin/admin-ajax.php\', 
        type: "POST", 
        /*action: \'submit_contact_form\',*/
        data: ({ "action": "submit_contact_form", "fullname": fullname, "email": email, "text": text }), 
        success: function (results){
            if ( IsEmail(email) == true) {
                //hide table
                $(\'.form_content\').hide(\'slow\', function() {
                    $(\'.form_content\').hide( "slow" );
                  });
                //show textboxes
                $(\'#aboutSuccess\').show("slow");
                $( "#aboutSuccess" ).append( "<iframe id=\\"pixel-thing\\" src=\\"http://54.xx.xx.xx/wp-content/themes/twentyfifteen-child/thePixel.html\\" width=\\"1\\" height=\\"1\\"  border=\\"0\\"></iframe>" );

            }
        }
    });
