How to create a new category in WordPress

Below is an example of using the wp_create_category function to create a new category in WordPress:

$category_id = wp_create_category( 'New Category' );

This code snippet calls the wp_create_category function and passes the name of the new category as a parameter. The function then creates a new category with the specified name and returns the category ID, which is stored in the $category_id variable.

How to create a new category with a parent category in WordPress

Here’s an example of using the wp_create_category function to create a new category with a specified parent category:

$parent_category_id = 5;
$category_id = wp_create_category( 'New Subcategory', $parent_category_id );

In this code snippet, we pass the name of the new subcategory as the first parameter and the ID of the parent category as the second parameter to the wp_create_category function. This creates a new subcategory under the specified parent category and returns the category ID, which is stored in the $category_id variable.

How to handle errors when creating a new category in WordPress

Below is an example of using the wp_create_category function and handling any errors that may occur:

$category_id = wp_create_category( 'New Category' );

if ( is_wp_error( $category_id ) ) {
 echo 'Failed to create category: ' . $category_id->get_error_message();
} else {
 echo 'Category created successfully with ID: ' . $category_id;
}

In this code snippet, we first call the wp_create_category function to create a new category. We then use an if statement to check if the result is a WordPress error object using the is_wp_error function. If an error occurs, we retrieve the error message using the get_error_message method and display it. Otherwise, we display a success message along with the category ID.
