How to change custom post type slug in wordpress

on

WordPress is a highly versatile content management system that offers a lot of flexibility, including the ability to change custom post type slug. This feature allows users to create unique content types beyond the standard posts and pages. However, there may be situations where you need to change the custom post type slug for various reasons such as improving the URL structure, avoiding conflicts, or branding purposes. In this article, we will explore different ways to change the custom post type slug in WordPress.

WordPress Change Post Slug Programmatically

One way to change the custom post type slug is programmatically, which means writing code to modify the slug. To do this, you need to access the functions.php file of your theme or create a plugin. Here’s an example of how to change the slug of a custom post type called “books” to “publications” using code:

function change_books_slug() {  $args = get_post_type_object( 'books' );  $args->rewrite['slug'] = 'publications';  register_post_type( 'books', $args );}add_action( 'init', 'change_books_slug', 1 );

In the above code, we first retrieve the post type object for “books” using the get_post_type_object() function. We then modify the rewrite rule for the slug using the $args->rewrite[‘slug’] variable and set it to “publications”. Finally, we register the custom post type again using the register_post_type() function with the modified arguments.

How to Get Custom Post Type Slug in WordPress

To get the slug of a custom post type in WordPress, you can use the get_post_type() function. This function returns the name of the current post type, which can be used as the slug. Here’s an example:

$post_type = get_post_type();echo $post_type;

This will output the current post type slug.

Change Permalink Structure for Custom Post Type

By default, WordPress uses the post name as the permalink structure for custom post types. However, you can customize the permalink structure using the rewrite parameter when registering the custom post type. Here’s an example:

function custom_post_type() {  $args = array(    'rewrite' => array( 'slug' => 'publications/%category%' ),  );  register_post_type( 'books', $args );}add_action( 'init', 'custom_post_type' );

In the aboe code, we have set the permalink structure for the “books” custom post type to include the category name in the URL. This will result in URLs like http://example.com/publications/science/fiction-book.

Remove Custom Post Type Slug from URL

Sometimes, you may want to remove the custom post type slug from the URL entirely to make it shorter or cleaner. This can be achieved by setting the “with_front” parameter to false when registering the custom post type. Here’s an example:

function custom_post_type() {  $args = array(    'rewrite' => array( 'slug' => 'book', 'with_front' => false ),  );  register_post_type( 'books', $args );}add_action( 'init', 'custom_post_type' );

In the above code, we have set the slug for the “books” custom post type to “book” and disabled the “with_front” parameter. This will result in URLs like http://example.com/science-fiction-book instead of http://example.com/book/science-fiction-book.

Get Post Type Slug

To get the slug of a custom post type in WordPress, you can use the get_post_type() function. This function returns the name of the current post type, which can be used as the slug. Here’s an example:

$post_type = get_post_type();echo $post_type;

This will output the current post type slug.

WordPress Change Default Post Slug

In addition to custom post types, WordPress also allows you to change the default post slug. By default, the slug for a post is based on the title of the post. However, you can customize this by adding the following code to your functions.php file:

function change_post_slug( $slug, $post_ID, $post_status, $post_type ) {    if ( $post_type == 'post' ) {        $slug = 'news-' . $post_ID;    }    return $slug;}add_filter( 'wp_unique_post_slug', 'change_post_slug', 10, 4 );

In the above code, we have added a filter to the wp_unique_post_slug hook to modify the slug for posts. In this example, we have added the prefix “news-” to the post ID to create a unique slug.

Supports in Custom Post Type

When registering a custom post type in WordPress, you can also specify which features or meta boxes you want to support. This can be done using the “supports” parameter in the $args array. Here’s an example:

function custom_post_type() {  $args = array(    'supports' => array( 'title', 'editor', 'thumbnail', 'author' ),  );  register_post_type( 'books', $args );}add_action( 'init', 'custom_post_type' );

In the above code, we have specified that the “books” custom post type supports the title, editor, thumbnail, and author meta boxes. You can customize this list based on your specific requirements.

Codex WordPress Custom Post Type

The WordPress codex provides detailed documentation on how to create custom post types in WordPress. You can refer to the following links for more information:

In conclusion, changing the custom post type slug in WordPress can be done in multiple ways, such as programmatically, through the permalink structure, or by removing the slug entirely. Additionally, you can also customize the supports for your custom post type and modify the default post slug. By following the steps outlined in this article and referring to the WordPress codex, you can easily make these changes and improve the URL structure and functionality of your website.
