Hello guy’s I’m Rahul and in today’s article we will learn how to create custom fields in WordPress using code or plugins. let’s get started.

What are custom fields in WordPress?

In WordPress, custom fields are a feature that allows users to add additional information to their posts, pages, or custom post types. basically, custom fields provide some extra options to add more information to content, such as metadata, images, links, etc.

A Simple Way to Create Custom Fields in WordPress:

Creating custom fields on our WordPress website is a simple process. We can do it using plugins or some pieces of code. There are some plugins available that can help us create custom fields without writing any code. If you want to use code instead, then we need to add a few lines of code to our functions.php file that is located in wp-content/themes/active-theme-folder.

Creating Custom Fields Using Plugins:

Step 1: Install a Custom Fields Plugin

To create custom fields in WordPress, you’ll need to install a custom fields plugin. Some popular options include Advanced Custom Fields, and Custom Field Suite. Simply go to the Plugins page in your WordPress dashboard, search for the plugin you want to use, click the “Install Now” button, and activate the plugin once it’s installed.

Step 2: Create a Custom Field Group

Once you’ve installed your custom fields plugin, the next step is to create a custom field group. A custom field group is a collection of custom fields that are grouped together for a specific purpose. To create a custom field group, go to the Custom Fields section in your WordPress dashboard, click the “Add New” button, and enter a name for your custom field group, along with any instructions or descriptions you want to include.

Step 3: Add Custom Fields to Your Group

To add custom fields to your group, click the “Add Field” button in your custom field group editor. You’ll be able to choose from a variety of field types, such as text fields, checkboxes, and radio buttons. Choose the field type that best suits your needs, and then fill in any additional information or settings as needed.

Step 4: Assign Your Custom Field Group to a Post Type

The final step is to assign your custom field group to a post type. This ensures that your custom fields are available whenever you create or edit posts of that type. To assign your custom field group to a post type, go to the “Location” section in your custom field group editor and select the post type you want to use. You can also choose to assign your custom field group to multiple post types if needed.

Creating Custom Fields using Custom Code

To create custom fields using code, you will need to add some PHP code to your functions.php file. Here are the steps to follow:

• Open your functions.php file in your WordPress theme.
• Add the following code to create a custom field:

function add_custom_meta_box() {
    add_meta_box(
        'prefix_meta_box',
        __( 'Custom Field', 'textdomain' ),
        'meta_box_callback',
        'post'
    );
}
add_action( 'add_meta_boxes', 'add_custom_meta_box' );

function meta_box_callback( $post ) {
    wp_nonce_field( basename( __FILE__ ), 'prefix_meta_box_nonce' );
    $prefix_stored_meta = get_post_meta( $post->ID );
    ?>
    <label for="meta-text" class="prefix-row-title"><?php _e( 'Custom Field Title', 'textdomain' )?></label>
    <input type="text" name="meta-text" id="meta-text" value="<?php if ( isset ( $prefix_stored_meta['meta-text'] ) ) echo $prefix_stored_meta['meta-text'][0]; ?>" />
    <?php
}

This code creates a custom meta box on the post editor screen that allows you to add a custom field to your post.

• Save the file, and you’re done!
