File Details

my-crud-form-plugin.php

Main plugin file that contains the plugin header, activation, deactivation, and database table creation. It also loads other plugin files and enqueues frontend and admin assets.

Creates the frontend enquiry form using the [contact_enquiry_form] shortcode. It validates, sanitizes, saves form data, and shows success or error messages.

includes/admin-enquiries.php

Creates the Enquiries admin menu and displays saved enquiries in a table. It also handles secure enquiry deletion using nonce and permission checks.

includes/settings.php

Creates the plugin settings page using the WordPress Settings API. It manages the form title, success message, and admin notification email.

assets/css/frontend.css

Adds basic styling to the frontend enquiry form, inputs, button, and messages. It loads only on pages containing the enquiry form shortcode.

assets/js/frontend.js

Handles frontend form behaviour when the user submits an enquiry. It disables the submit button and changes its text to prevent duplicate submissions.
