Wordpress幫助表單提交後重定向

Question

我希望在表單提交後讓我的聯繫表單重定向。我不知道它是如何做到的。這是我的代碼，它也給我一個錯誤。

<?php 

// If the form is submitted 
if(isset($_POST['submit'])) { 

    // Include WordPress Core Functions 
    $wp_include = '../wp-load.php'; 
    while(!@include_once($wp_include)) { $wp_include = '../'.$wp_include; } 


    // 
    // Field Validation 
    // 

    // Check to make sure that the name field is not empty 
    if(trim($_POST['cf_name']) == '') { 
     $has_error = true; 
    } 
    else { 
     $name = trim($_POST['cf_name']); 
    }

    if(trim($_POST['cf_subject']) == '') { 
     $has_error = true;

     // Send E-Mail 
     $mail_sent = wp_mail($receiver, $subject, $message, $headers); 
     if($mail_sent) 
      echo "<p class='info-box success'>".$_POST['cf_success_msg']."</p>"; 
     else 
      echo "<p class='info-box error'>The message couldn't be sent because an internal error occured.</p>"; 

     echo "<p class='info-box error'>".$_POST['cf_error_msg']."</p>"; 
    }

在WordPress的重定向功能是wp_redirect，例如

if($mail_sent) { 
    wp_redirect('/my-target'); 
    exit(); 
} else { 
    //output your warning 
}
