How to add custom post types without the CPT plugin in WordPress?

Step 1: Create a Child Theme (Optional but Recommended)

Before modifying the functions.php file, it's a good practice to create a child theme to ensure your changes are not lost when the parent theme is updated. If you're not familiar with creating a child theme, you can find instructions in the WordPress Child Themes documentation.

Step 2: Visit GenerateWP

Visit GenerateWP website

Go to the GenerateWP Custom Post Type Generator.

Step 3: Fill Out the Form

• Post Type Name: Enter the name for your custom post type (e.g., book).
• Singular Name: Enter the singular name (e.g., Book).
• Plural Name: Enter the plural name (e.g., Books).
• Slug: This is the URL-friendly version of the post type name (e.g., book).

Labels Section

Fill in the labels for the custom post type. This includes names like Add New, Edit, View, etc. These labels will be used in the WordPress admin.

• Show UI: Check this box to show the custom post type in the admin UI.
• Has Archive: Check this if you want to enable archiving for this post type.
