How To create custom taxonomy in WordPress?

Creating custom post types in WordPress can be a great way to organize and display different types of content on your site. Whether you want to create a portfolio, team member section, or custom product listings, custom post types can make it easy to manage and display your content in a structured way. Here’s a step-by-step guide on how to create a custom post type in WordPress:

  1. The first step is to create a new PHP file in your theme’s directory. You can name this file anything you like, but it’s a good idea to use a name that reflects the custom post type you’re creating, such as “portfolio.php” or “team-members.php”.
  2. In the new file, you will need to define your custom post type. You can do this by using the register_post_type() function. Here’s an example of how to create a custom post type called “Portfolio”:
Copy codefunction create_portfolio_post_type() {
    register_post_type( 'portfolio',
        array(
            'labels' => array(
                'name' => __( 'Portfolio' ),
                'singular_name' => __( 'Portfolio' )
            ),
            'public' => true,
            'has_archive' => true,
            'rewrite' => array('slug' => 'portfolio'),
        )
    );
}
add_action( 'init', 'create_portfolio_post_type' );

Be sure to change the names and arguments to match your custom post type.

  1. Next, you can add custom fields to your custom post type by using the add_meta_box() function. You can use this function to create custom fields for things like images, text, and links. Here’s an example of how to create a custom field for a featured image:
Copy codefunction add_portfolio_meta_box() {
    add_meta_box(
        'portfolio_meta_box', // ID
        'Portfolio Details', // Title
        'show_portfolio_meta_box', // Callback function
        'portfolio', // Screen
        'normal', // Context
        'high' // Priority
    );
}
add_action( 'add_meta_boxes', 'add_portfolio_meta_box' );
  1. You can now create the callback function that will display the custom field in the admin area. The function should be called show_portfolio_meta_box() in this example.
Copy codefunction show_portfolio_meta_box() {
    global $post;
    $meta = get_post_meta( $post->ID, 'portfolio', true );
    ?>
    <input type="hidden" name="portfolio_meta_box_nonce" value="<?php echo wp_create_nonce( basename(__FILE__) ); ?>">
    <p>
        <label for="portfolio[image]">Featured Image</label>
        <input type="text" name="portfolio[image]" id="portfolio[image]" class="regular-text" value="<?php echo $meta['image']; ?>">
    </p>
    <?php
}
  1. Finally, you will need to save the custom field data when the post is saved. You can do this by using the save_post

Creating custom taxonomies in WordPress can be a great way to organize and categorize different types of content on your site. By using custom taxonomies, you can create new categories and tags that are specific to your custom post types. Here’s a step-by-step guide on how to create a custom taxonomy in WordPress:

  1. The first step is to create a new PHP file in your theme’s directory. You can name this file anything you like, but it’s a good idea to use a name that reflects the custom taxonomy you’re creating, such as “genre.php” or “location.php”.
  2. In the new file, you will need to define your custom taxonomy. You can do this by using the register_taxonomy() function. Here’s an example of how to create a custom taxonomy called “Genre” for a custom post type called “books”:
Copy codefunction create_book_genre_taxonomy() {
    register_taxonomy(
        'genre',
        'books',
        array(
            'label' => __( 'Genre' ),
            'rewrite' => array( 'slug' => 'genre' ),
            'hierarchical' => true,
        )
    );
}
add_action( 'init', 'create_book_genre_taxonomy' );

Make sure to change the names and arguments to match your custom taxonomy and post type.

  1. You can now use the custom taxonomy to organize and categorize the content of the custom post type “books”. You can do this by visiting the post editor for a book and selecting the appropriate genre from the new “Genre” taxonomy meta box.
  2. To display the custom taxonomy on the front-end of your site, you can use the WordPress template tags such as the_terms() to display the terms of the custom taxonomy associated with a post.
  3. If you want to display the custom taxonomy in a different way, you can also create a custom template file and use a wp_query to get the posts of the custom taxonomy and loop through them to display the data.

By following these steps, you can easily create a custom taxonomy in WordPress to organize and categorize your content. Custom taxonomies can be used to create new categories and tags that are specific to your custom post types, making it easier for visitors to find the content they are looking for.
