Core WordPress Concepts

Understanding core WordPress concepts is key for any interview. These concepts form the foundation of WordPress development. Let’s explore some important areas.

Themes And Plugins

Themes and plugins are essential in WordPress. A theme controls the design of a site. It includes templates and stylesheets. You can find free themes in the WordPress theme directory.

Plugins extend the functionality of a WordPress site. They can add features like contact forms, SEO tools, or eCommerce capabilities. Plugins can be installed from the WordPress plugin repository.

Element	Description
Theme	Controls the design and layout of the site
Plugin	Adds extra functionality to the site

Custom Post Types

WordPress comes with default post types like posts and pages. But, you can create custom post types for different content. For example, you might create a custom post type for portfolio items.

Use the register_post_type() function to create custom post types. This function defines the parameters and features of the new post type.

Here is an example of how to register a custom post type:

function create_portfolio_post_type() {
  register_post_type('portfolio',
    array(
      'labels' => array(
        'name' => __('Portfolios'),
        'singular_name' => __('Portfolio')
      ),
      'public' => true,
      'has_archive' => true,
      'rewrite' => array('slug' => 'portfolios'),
    )
  );
}
add_action('init', 'create_portfolio_post_type');

Custom post types enhance the organization of your content. This makes it easier to manage and display different types of content.

Development Environment

Creating a development environment is crucial for WordPress development. It allows you to test new features safely. You can troubleshoot issues without affecting the live site. Let’s explore key aspects of setting up a local environment and the tools you need.

Setting Up Local Environment
