I have REST endpoint in WordPress and I am trying to ping it with jQuery from the fronted script. This works when questioned via browser: /

But it does not work when I am trying to reach it from the frontend with jQuery. I have tried different AJAX requests but I am unable to get any response. Does anyone know what am I doing wrong?

Rest endpoint here:

// REST END POINT FOR THE VIDEOS
function wpc_ylp_rest_videos( ) {


  $myObj->name = "John";
  $myObj->age = 30;
  $myObj->city = "New York";

  $myJSON = json_encode($myObj);

  echo $myJSON;


}

add_action( 'rest_api_init', function () {
  register_rest_route( 'wpc_ylp/v2', '/videos', array(
    'methods' => 'GET',
    'callback' => 'wpc_ylp_rest_videos',
  ) );
} );

jQuery AJAX trying to reach the endpoint:

    jQuery.get( target = '/wp-json/wpc_ylp/v2/videos/', function( data ) {
      console.log( 'DATA',data )
    });

or

    jQuery.ajax({
      url: '/wp-json/wpc_ylp/v2/videos'
    }).done(function( data ) {
        console.log('dataxxx',data);
    });

• Why does your URL have target = before it? Have you confirmed your endpoint is there by visiting it in your browser? It's extremely unusual that your endpoint encodes and outputs its own content, is there a reason you don't return the data from the function like the docs? Also where is the code that creates $myObj? Is there more to your endpoint that's been removed to fit in this question? – Tom J Nowell ♦ Commented Dec 12, 2019 at 19:25
• Yes, as per the first sentence of my question when visited via browser this works perfectly well. What I really need to know why I am unable to access it with jQuery AJAX while it can be visited via browser with no issues. That's all. Thanks Tom – xyz83242 Commented Dec 12, 2019 at 20:19

First, lets fix your endpoint:

function wpc_ylp_rest_videos( ) {
  $myObj->name = "John";
  $myObj->age = 30;
  $myObj->city = "New York";
  $myJSON = json_encode($myObj);
  echo $myJSON;
}

There are a few problems here:

• callbacks for REST API endpoints are meant to return their data, like shortcodes. The REST API does the JSON encoding, you're not meant to echo
• $myObj appears to have been summoned out of nowhere, this will generate a large amount of PHP notices and errors. Never do this, PHP will have to fill in the gaps, and relying on computer to "get what you meant" rarely works out
• There's actually a first parameter given to you that lets you read in parameters instead of using $_GET or $_POST, that allows you to use a lot of the features

It would be much better like this:

function wpc_ylp_rest_videos( $request ) {
    return [
        'name' => 'John',
        'age'  => 30,
        'city' => 'New York',
    ];
}

Second, I tested your AJAX request code with this:

jQuery.get( '/wp-json/wp/v2/posts/', function( data ) {
  console.log( 'DATA',data )
});

The result worked as desired
