wordpress PHP与Ajax调用

Im looking to return user data back as a string through ajax with wordpress

Iv got the basic concept down

PHP

this is placed in my functions.php 

add_action('template_redirect', 'edit_user_concept');
function edit_user_concept(){
      $id = $_POST['getbyID'];
      $user_info = get_userdata($id);
      echo 'Username: ' . $user_info->user_login . "
";
      echo 'User roles: ' . implode(', ', $user_info->roles) . "
";
      echo 'User ID: ' . $user_info->ID . "
";
}

Jquery/JS

    $.ajax({
         url: "http://www.example.com/",
         method: "POST",
         data: {
             getbyID: "23",
         },
         success: function(response){
             console.log(response);
             //example script logic here
         }
    })

the console log result is correct how ever its also logging lots of html elements that are not included in this. Such as

im not exactly sure why.

here is a small example to large to post in its full

Username: someusername
User roles: subscriber
User ID: 23
<!DOCTYPE html>
<html lang="en-US">
<div id="loadtheme" class="loadtheme"></div>
<head>

etc etc etc....

Any thoughts?

    You are echoing the html without stopping it anywhere, you can use json response here, for json, first of all you need to use dataType: "json" in your ajax request as:

     url: "http://www.example.com/",
 method: "POST",
 dataType: "json" // need to use datatype here.
 data: {
     getbyID: "23",
 }

    Now, you need to store data in an array in your PHP as:

    $result = array();
$result['Username'] = $user_info->user_login;
$result['User_roles'] = implode(', ', $user_info->roles);
$result['User_id'] = $user_info->ID;

    Now, you can use json_encode():

    echo json_encode($result);

    You can print json result as like:

    console.log(response.Username); // will print username
console.log(response.User_roles); // will print user roles
console.log(response.User_id); // will print user id

    Complete Example:

    $.ajax({
     url: "http://www.example.com/",
     method: "POST",
     dataType: "json" // json data type
     data: {
         getbyID: "23",
     },
     success: function(response){
         console.log(response.Username);
         console.log(response.User_roles);
         console.log(response.User_id);
         //example script logic here
     }
 });

    PHP:

    <?php
function edit_user_concept(){
  $id = $_POST['getbyID'];
  $user_info = get_userdata($id);
  $result = array();
  $result['Username'] = $user_info->user_login;
  $result['User_roles'] = implode(', ', $user_info->roles);
  $result['User_id'] = $user_info->ID;
  echo json_encode($result); // will return json response
}
?>
