I found a basic tutorial online which gave the rundown on how to create a plugin from scratch and sets up a new custom post type. I could not find any basic coupon plugins that accomplished what I wanted, why I decided to look into creating one myself.

Unfortunately after completing the tutorial, I came to the part where I actually view the page, only to be greeted with a "Page Not Found" despite publishing my post. Can anyone check this out and let me know exactly what I am doing wrong?

// Register the Custom Post Type "Coupon"
function register_cpt_coupon()
{
    $labels = array(
        'name' => _x( 'Coupons', 'coupon' ),
        'singular_name' => _x( 'Coupon', 'coupon' ),
        'add_new' => _x( 'Add New', 'coupon' ),
        'add_new_item' => _x( 'Add New Coupon', 'coupon' ),

        'not_found_in_trash' => _x( 'No coupons found in Trash', 'coupon' ),
        'parent_item_colon' => _x( 'Parent Coupon:', 'coupon' ),
        'menu_name' => _x( 'Coupons', 'coupon' ),
    );

    $args = array(

    register_post_type( 'coupon', $args );
}

add_action( 'init', 'register_cpt_coupon' );

// Create Genre Taxonomy type

    register_taxonomy(

            )
        )
    );
}
add_action( 'init', 'genres_taxonomy');

// Function used to automatically create Coupon page.
function create_coupon_pages()
{
   //post status and options
    $post = array(

    //insert page and save the id
    $newvalue = wp_insert_post( $post, false );

    //save the id in the database
    update_option( 'couponpage', $newvalue );
}

// // Activates function if plugin is activated
register_activation_hook( __FILE__, 'create_coupon_pages');

You quite likely need to simply visit your permalink settings page to refresh. Goto Admin > Settings > Permalinks. Then try your URL on the front-end again.

  • Thank you, I cannot believe it was that simple but that was indeed the answer. Only problem with Wordpress, there is literally too much information available sometimes. Can you share why exactly this is necessary? Oct 31, 2014 at 12:05
  • Glad that solved it for you. Sorry, but I cannot explain exactly why this is necessary. I wish I could but I do not have enough understanding of how WP is creating the rewrite rules in the first place. There are certainly other members of this community that do have that knowledge.
