我正在尝试使用Ajax通过我创建的Web表单发送电子邮件,但我迷路了.我不知道Ajax如何在wordpress中运行.

我首先创建了一个动作

add_action( 'wp_ajax_sITeWideMessage','WPSe_sendmail' );

应该检索数据并发送邮件的功能是：

function wpse_sendmail()
{
    $for = like_escaPE($_POST['forwhat']);
    $email = like_escape($_POST['email']);
    $headers = 'From: '.$email ."\r\n".'Reply-to: '.$email;
    $message = like_escape($_POST['message_message']);
    $respond = like_escape($_POST['message_email']);

    wp_mail( "support@ontrgt.net","(OTN) Support: ".$support,$message,$headers); 
}

最后,js是这样的：

$("#contact-send").click(function(){
    VAR forwhat = $("#contact-for").val();
    var name = $("#contact-name").val();
    var email = $("#contact-email").val();

    $.post( "<?PHP echo esc_js( site_url() ) ?>",{ siteWideMessage:"null",forwhat: forwhat,name: name,email:email },function(){
            console.LOG("success");
    });
});

我不太清楚我在这里缺少什么.有人可以帮我理解wordpress的Ajax流程吗？

UPDATE

到目前为止,我更新了我的代码：

PHP

add_action( 'wp_ajax_siteWideMessage','wpse_sendmail' );
add_action( 'wp_ajax_noPRiv_siteWideMessage','wpse_sendmail' );

function wpse_sendmail()
{
    $for = $_POST['forwhat'];
    $email = $_POST['email'];
    $headers = 'From: '.$email ."\r\n".'Reply-To: '.$email;
    $message = $_POST['message_message'];
    $respond = $_POST['message_email'];

    /*if(wp_mail( "support@ontrgt.net","(OTN) Support: ".$for,$headers))
    {
        echo "WOOHOO";
    }*/

    if($for)
    {
        //Just to see if there is any response.
        echo "Whoohoo";
    }

    die();
}

JS

$("#contact-send").click(function(){
    var forwhat = $("#contact-for").val();
    var name = $("#contact-name").val();
    var email = $("#contact-email").val();

    var data = { action:'siteWideMessage',forwhat:forwhat,name:name,email:email };
    $.post('<?PHP echo admin_url("admin-ajax.PHP"); ?>',data,function(response) {
        alert(response);
    });
});

wordpress仍然没有响应我的AJAX命令.我正在使用inspect元素,我看不到任何数据被传递.

add_action( 'wp_ajax_siteWideMessage','wpse_sendmail' );

$("#contact-send").click(function(e){

    e.preventDefault(); // if the clicked element is a link

    //...

    var data = { 'action':'siteWideMessage','more':'values' };

    $.post('<?PHP echo admin_url('admin-ajax.PHP'); ?>',function(response) {
        console.log(response);
    });

});

function wpse_sendmail()
{
    // Process the post data...

    if(mail(...)) {
        echo 'success';
    }
    else {
        echo 'Failed';
    }

    die();
}
