Question

这是我第一次在WP上使用ajax。我正在处理一个简单的联系表单，由于某种原因，每当我点击提交时，我都会收到错误：

在控制台上：

 POST http://54.xxx.xx.xx/wp-admin/admin-ajax.php 500 (Internal Server Error)jquery.js?ver=1.11.1:4 m.ajaxTransport.sendjquery.js?ver=1.11.1:4 m.extend.ajaxmain.js:66 (anonymous function)jquery.js?ver=1.11.1:3 m.event.dispatchjquery.js?ver=1.11.1:3 m.event.add.r.handle

这是我的ajax部分：

//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.xxx.xx.xx/wp-content/themes/twentyfifteen-child/thePixel.html\" width=\"1\" height=\"1\"  border=\"0\"></iframe>" );

            }
        }
    }); 


});

这是我的php fucntion：

// 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 = "mail@main.com";

        $host = "ssl://smtp.gmail.com:465";
        $username = 'mainmain@mail.com';
        $password = 'pass';

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

        $headers = array ('From' => $email, 'To' => $email_to,'Subject' => $email_subject);
        $smtp = Mail::factory('smtp',
          array ('host' => $host,
            'auth' => true,
            'username' => $username,
            'password' => $password));

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

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


}

可能是错误的原因？

我在php functions.php文件中尝试了var_dump（）变量，它们都显示正常。

我添加require_once "Mail.php";时在我的php文件的顶部，页面只是停止加载。我不确定这是不是问题。所以我在没有它的情况下尝试（？）

错误500正在抛出，因为您的服务器没有响应您的呼叫。

你是否在php文件的开头尝试过。

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

使用firebug，它会向您发送对服务器和响应的调用，以便您可以看到错误。

如果您看到一个空白页面，那么您错过了PHP文件中某处的语法。查看括号，冒号和分号

为什么我得到＆＃34; POST http：//54.xx.xx.xx/wp-admin/admin-ajax.php 500（内部服务器错误）＆＃34;什么时候使用Wordpress + Ajax？
