Wp_reDirect()在WordPress中插入PHP插件时不起作用

这是我在插入PHP插件中的代码。我在WordPress的一个页面中添加了这个插件生成的PHP代码段。这个wp_redirect 无法使用此代码段。

// define variables and set to empty values
$emailErr = $passwordErr = "";
$email = $password = "";

function test_input($data) {
  $data = trim($data);
  $data = stripslashes($data);
  $data = htmlspecialchars($data);
  return $data;
}



if ($_SERVER["REQUEST_METHOD"] == "POST") {
  if (empty($_POST["email"])) {
    $emailErr = "Email is required";
  } 
  else {
    $email = test_input($_POST["email"]);
    // check if e-mail address is well-formed
    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
      $emailErr = "Invalid email format"; 
    }
  }

  if (empty($_POST["password"])) {
    $passwordErr = "Password is required";
  } else {
    $password = test_input($_POST["password"]);
    // check if URL address syntax is valid (this regular expression also allows dashes in the URL)
    //if (!preg_match("/\\b(?:(?:https?|ftp):\\/\\/|www\\.)[-a-z0-9+&@#\\/%?=~_|!:,.;]*[-a-z0-9+&@#\\/%=~_|]/i",$website)) {
    //  $websiteErr = "Invalid URL"; 
    //}


  if ($emailErr == "" && $passwordErr == "")
  {
  wp_redirect("https://grenstonhrs.000webhostapp.com",301);
  exit;
  }
  }

}
