FAQs for WordPress Plugin Development

What is the basic file structure required for a WordPress plugin?

A WordPress plugin requires a main PHP file with a plugin header comment containing metadata like Plugin Name, Version, Author, and Description. The file should be placed in the wp-content/plugins directory.

How do I register activation and deactivation hooks in a plugin?

Use register_activation_hook() and register_deactivation_hook() functions. Example: register_activation_hook(__FILE__, 'my_activation_function'); These hooks run when the plugin is activated or deactivated.

What is the purpose of action hooks in WordPress plugin development?

Action hooks allow you to execute custom code at specific points during WordPress execution. Use add_action() to hook your functions into WordPress core actions, like 'init', 'admin_menu', or 'wp_head'.

How can I add a settings page for my plugin?

Use add_menu_page() or add_submenu_page() functions in an admin_menu action hook to create a settings page. Then use the Settings API to register and manage plugin settings.

What's the proper way to enqueue scripts and styles in a plugin?

Use wp_enqueue_script() and wp_enqueue_style() within a wp_enqueue_scripts hook for frontend, or admin_enqueue_scripts for admin pages. Always include dependencies and version numbers.

How do I create custom database tables for my plugin?

Use dbDelta() function in your activation hook to create tables. Format the SQL statement correctly with proper syntax and use the WordPress $wpdb global object for database operations.

What are filters and how do I use them in plugin development?

Filters modify data before it's displayed or saved. Use add_filter() to hook into existing filters or create custom ones. Example: add_filter('the_content', 'my_content_filter');

How can I make my plugin translation-ready?

Use __(), _e(), or other internationalization functions for text strings. Create a POT file, and load text domain using load_plugin_textdomain() in the plugins_loaded hook.

What's the best practice for plugin security?

Always validate and sanitize input data, use nonces for forms, check user capabilities, escape output data, and follow WordPress coding standards. Use wp_verify_nonce() for form submissions.

How do I handle plugin updates?

Use version numbers in your plugin header. Implement upgrade routines in activation hook or separate function. Consider using the WordPress update API for automatic updates from your server.
