Code not Printing playlist details

Hi,

I have this code but whenever I submit a URL into the box, it should output the details of the playlist but nothing is showing. Can someone help please?

<?php // Check if user has submitted the form // Check if user has submitted the form if ( isset( $_POST[ 'playlist_url' ] ) ) { // Retrieve playlist ID from Spotify Playlist URL $playlist_url = $_POST[ 'playlist_url' ]; $playlist_parts = explode( '/', parse_url( $playlist_url, PHP_URL_PATH ) ); $playlist_id = end( $playlist_parts ); // Spotify Web API endpoint for retrieving a playlist $endpoint = "https://api.spotify.com/v1/playlists/{$playlist_id}"; // Set up cURL request with Spotify API credentials $client_id = mdjm_get_option( 'spotify_api_key' ); $client_secret = mdjm_get_option( 'spotify_secret_key' ); $spc_init = curl_init(); curl_setopt( $spc_init, CURLOPT_URL, 'https://accounts.spotify.com/api/token' ); curl_setopt( $spc_init, CURLOPT_RETURNTRANSFER, 1 ); curl_setopt( $spc_init, CURLOPT_POST, 1 ); curl_setopt( $spc_init, CURLOPT_POSTFIELDS, 'grant_type=client_credentials' ); curl_setopt( $spc_init, CURLOPT_HTTPHEADER, array( 'Authorization: Basic ' . base64_encode( $client_id . ':' . $client_secret ) ) ); $result = curl_exec( $spc_init ); $status_code = curl_getinfo( $spc_init, CURLINFO_HTTP_CODE ); if ( curl_errno( $spc_init ) ) { $error_message = curl_error( $spc_init ); echo "cURL Error: " . $error_message; } else { // Decode the JSON response from Spotify $data = json_decode( $result, true ); if ( $data === null ) { echo "Error: Unable to decode the JSON response from Spotify."; } else { // Print the JSON response and status code to the screen echo "<pre>"; echo "Status Code: " . $status_code . "\n"; echo json_encode( $data, JSON_PRETTY_PRINT ); echo "</pre>"; } } // Close cURL session curl_close( $spc_init ); } // Check for errors in the Spotify response if ( isset( $data[ 'error' ][ 'message' ] ) ) { $error_message = $data[ 'error' ][ 'message' ]; echo "Error: " . $error_message; } else { // Extract relevant details from playlist JSON $name = $data[ 'name' ]; $description = $data[ 'description' ]; $tracks = $data[ 'tracks' ][ 'items' ]; // Print playlist details echo "<h1>{$name}</h1>"; echo "<p>{$description}</p>"; // Loop through tracks and print track details foreach ( $tracks as $track ) { $track_name = $track[ 'track' ][ 'name' ]; $artists = array(); foreach ( $track[ 'track' ][ 'artists' ] as $artist ) { $artists[] = $artist[ 'name' ]; } $artist_name = implode( ', ', $artists ); echo "<p>{$track_name} by {$artist_name}</p>"; } } ?>

Client credentials only work with playlists that are public and are displayed on your/someone's profile.

The playlist is public and attached to my profile.

The data of your playlist is not printed, because it's never requested. You only specified the URL of the $endpoint, but aren't using it anywhere in your code. The $data your code is trying to echo is the acces_token, and not the data of your playlist.
(I just noticed it after I had a chance to run the code myself.)
