I am new to wordpress plugin development and I have a created a simple contact form plugin which takes name, email, and message as input, I just want to show the data saved in the form in the wordpress dashboard. Here's a brief overview of what I've done so far: 1- Created a contact form using the add_shortcode function. 2- Handled form submissions and saved the data using wp_insert_post. 3- Set up a custom post type for form submissions and customized the dashboard view. Here's the code: <?php if(!class_exists('DemoPlugin')) { class DemoPlugin { public function __construct() { //Create custom post type add_action('init', [$this, 'create_custom_post_type']); // add_action('init', [$this, 'list_all_shortcodes']); //Add Shortcode add_shortcode('demo_plugin_contact', [$this, 'demo_plugin_contact']); //Register REST API add_action('rest_api_init', [$this, 'register_rest_api']); } public function create_custom_post_type() { $args = [ 'public' => true, 'has_archive' => true, 'supports' => ['title', 'editor', 'custom-fields'], 'exclude_from_search' => true, 'publicly_queryable' => false, 'capability' => 'manage_options', 'labels' => [ 'name' => 'Contact Form(Demo-Plugin)', 'singular_name' => 'Contact Form Entry', 'menu_icon' => 'dashicons-media-document', ] ]; register_post_type('demo-plugin', $args); } public function register_rest_api() { register_rest_route('demo-plugin-form/v1', 'send-email', [ 'methods' => 'POST', 'callback' => [$this, 'handle_contact_form'] ]); } public function handle_contact_form($data) { $headers = $data->get_headers(); $params = $data->get_params(); $nonce = $headers['x_wp_nonce'][0]; if(!wp_verify_nonce($nonce, 'wp_rest')) { return new WP_REST_Response('Message not sent', 422); } $name = sanitize_text_field($params['name']); $email = sanitize_email($params['email']); $message = sanitize_text_field($params['message']); $post_id = wp_insert_post([ 'post_type' => 'demo-plugin', 'post_title' => "Contact Enquiry from $email", 'post_content' => "$email", 'post_status' => 'publish', ]); if($post_id) { return new WP_REST_Response('Form Submitted successfully', 200); } } } } new DemoPlugin();
