I think we can simplify it with: $request = new WP_REST_Request( ‘GET’, ‘/wp/v2/posts’ ); $response = rest_do_request( $request ); $data = rest_get_server()->response_to_data( $response, true ); by using rest_do_request().
You can modifiy REST API responses in themes functions.php like this. function ws_register_images_field() { register_rest_field( ‘post’, ‘images’, array( ‘get_callback’ => ‘ws_get_images_urls’, ‘update_callback’ => null, ‘schema’ => null, ) ); } add_action( ‘rest_api_init’, ‘ws_register_images_field’ ); function ws_get_images_urls( $object, $field_name, $request ) { $medium = wp_get_attachment_image_src( get_post_thumbnail_id( $object->id ), ‘medium’ ); $medium_url = $medium[‘0’]; $large = wp_get_attachment_image_src( … Read more
BODA82’s answer helped, but eventually I realized that I should have replaced responseText with responseJSON method in my JavaScript code. In the example below I was storing the Ajax response results in a variable. I didn’t know there was a specific method to get the response in JSON. In a such way the object/array with … Read more
serialize representation can be stored in text and reversed JSON representation can be stored in text but cannot always be precisely reversed Run this example: $query = new WP_Query(); var_dump( $query ); var_dump( unserialize( serialize( $query ) ) ); var_dump( json_decode( json_encode( $query ) ) ); After going through serialize accurate WP_Query object is re-created. … Read more
If you want the D.I.Y. route… The post type in this example is set to ‘post’ but you can see where to change it. Here is a working example to pull the data ( first page in this example ), parse the response, create a class for the clean(er) data, generate posts from that data … Read more
I ended up extending the API like suggested in the comments to my question, although I was hoping there was a default route that fetched all posts of all post types. Apparently, there isn’t. So here’s my solution: add_action( ‘rest_api_init’, ‘custom_api_get_all_posts’ ); function custom_api_get_all_posts() { register_rest_route( ‘custom/v1’, ‘/all-posts’, array( ‘methods’ => ‘GET’, ‘callback’ => ‘custom_api_get_all_posts_callback’ … Read more
Sorry for answering my own question but it may help some other devs too. I created this additional filter ‘json_query_var-meta_query’that returns the necessary arguments. function adjustQrry($data){ $args = array(); $args[‘relation’] = ‘AND’; foreach ($data as $key=>$value) { if ( ‘relation’ === $key ) { $args[‘relation’] = $data[‘relation’]; } if ( substr($key, 0, 3) === ‘key’ … Read more
it seems the latter only accepts x-www-form-urlencoded That’s not completely true. WordPress admin-ajax.php takes the action from $_REQUEST[‘action’] and $_REQUEST is equal to: array_merge($_POST, $_GET); But what many people don’t realize is that $_GET in PHP is not the data was sent to page using HTTP GET method, in fact, you can use whatever HTTP … Read more
Based on the code provided it looks like you are misunderstanding how wp_localize_script works. The signature of the function looks like this: wp_localize_script( $handle, $name, $data ); Where $handle is the name of a JavaScript file you have registered or enqueued before calling wp_localize_script. Take a look at the example in the codex (I’ve added … Read more
To anyone who might still be hitting this problem, here’s a checklist: Make sure you are authenticated AND your user has the list_users capability. Example: When adding a custom role, I make sure to add the list_users capability. The user should also be logged in (what authenticated means) when making the request. By default, only … Read more
