Don't call flush after the register function. (Many examples above do this.) Instead, add two functions, one attached to the "register_activation_hook( __FILE__, 'activate_cb' );" which in turn adds an action to 'init' (priority 11 just to be sure) and that function in turn flushes the rewrite. Otherwise, you are flushing on every single page load (not good).

Do you know why you shouldn't put it in, say, a function called by an init hook? I've been testing it and it seems to work fine . . .

I'm looking for help with a similar problem here:

http://wordpress.org/support/topic/need-help-diagnosing-permalink-problem-reports?replies=1

My plugin code works fine on my site and those of some other users who are happy with it, but I'm also getting isolated reports of 404 errors when people try to use the permalinks.

Hi there, I'm trying to use this method with custom date meta for my permalink rewrite. I can't figure out for the life of me why I can't get around the 404 issue. Ive even added in your flush_rewrite_rules into my code and nothing. Settings > Permalink Structure: /%category%/%postname%/ Here is my function below- it's working fine for creating the actual permalink but i cannot access the post without getting the 404.

add_filter('post_type_link','calendar_link_filter',1,3);

function calendar_link_filter( $post_link, $id = 0, $leavename = FALSE ) {
        $post = get_post($id);
        if($post->post_type != 'super_duper') {
                return $post_link;
        }
        $date = get_post_meta($post->ID,'event_start_date',true);
        $date = strtotime($date);
        $str = $post_link;
        $str = str_replace('%cal_year%',date("Y",$date),$str);
        $str = str_replace('%cal_month%',date("m",$date),$str);
        $str = str_replace('%cal_day%',date("d",$date),$str);
        return $str;
		
}


add_action( 'init', 'create_my_post_types' );

function create_my_post_types() {
	register_post_type( 'super_duper',
		array(
			'labels' => array(
				'name' => __( 'Super Dupers' ),
				'singular_name' => __( 'Super Duper' )
			),
			'hierarchical' => false,
			'show_ui' => true, // UI in admin panel
            'publicly_queryable' => true,
            'rewrite' => true,
			'public' => true,
			'rewrite' => array('slug' => 'events8/%cal_year%/%cal_month%/%cal_day%'),
			
			
		)
	);
	flush_rewrite_rules();
}

[...] you may need to “flush” them). The plugin does flush the rewrite rules on activation as recommended, however some websites seem to require a manual flush. To do so, go to your admin menu settings [...]

Ah, good idea to throw everything into init.

I just tried this out, and it worked beautifully to fix my permalink issues. In my blog theme, I have the custom post type initialized in my functions.php file. I added the flush_rewrite_rules(); function to the file, within the create_my_post_types() function that initializes my custom post type (self-named, not a wordpress function) , but after the register_post_type() function that defines the parameters of the custom post type. confused? Well here's my code, hopefully this will display properly:


add_action( 'init', 'create_my_post_types' );

function create_my_post_types() {
	register_post_type( 'genera',
		array(
			'labels' => array(
	            'name' => __( 'GENERA' ),
	            'singular_name' => __( 'GENERA Entry' ),
	            'add_new' => __( 'Add New' ),
	            'add_new_item' => __( 'Add New GENERA Entry' ),
            	'edit' => __( 'Edit' ),
            	'edit_item' => __( 'Edit GENERA Entry' ),
	            'new_item' => __( 'New GENERA Entry' ),
	            'view' => __( 'View GENERA' ),
	            'view_item' => __( 'View GENERA Entry' ),
	            'search_items' => __( 'Search GENERA' ),
	            'not_found' => __( 'No GENERA Entries found' ),
	            'not_found_in_trash' => __( 'No GENERA Entries found in Trash' ),
	            'parent' => __( 'Parent GENERA Entry' ),
),
			'public' => true,
			'show_ui' => true,
            'publicly_queryable' => true,
			'rewrite' => true,
            'exclude_from_search' => false,
			'menu_position' => 20,
			/* Global control over capabilities. */
            'capability_type' => 'post',
            'supports' => array( 'title', 'editor', 'comments', 'trackbacks', 'revisions', 'author', 'excerpt', 'custom-fields', 'thumbnail', 'page-attributes' ),
		)
	);
	flush_rewrite_rules();
}

in order to see the new permalink structure, you will of course have to have 'rewrite' set to => true
