Custom post type single-{custom}.php not working

5 Views

I made a custom post type with the machine name special_media_post and wordpress is simply not seeing the single-special_media_post.php. I am at a complete lose. It keeps defaulting to the index.php

Here is my code for my custom post type and its taxonomies:

register_taxonomy( 'type', 'special_media_post', $args );
}

// Hook into the 'init' action
add_action( 'init', 'special_media_post', 0 );

// Hook into the 'init' action
add_action( 'init', 'media_year', 0 );

// Hook into the 'init' action
add_action( 'init', 'media_type', 0 );

If there is something else you need to see, I can put it up, but it doesn’t even see it if I put an echo ‘Hello World’ in there. So it is simply not seeing either the single-special_media_post.php or the archive-special_media_post.php

  1. Visit the permalinks page (which will flush it) and check again. WordPress probably just needs to be nudged to recognize your addition to the hierarchy.

  2. Change the code

    From :

     'has_archive'         => true,

    To :

     'has_archive'         => false,

    And then go to permalink page, change to default and go back to your “pretty permalink”

    %postname%/

    Now it should work.

    The reason why its not going to the single-{custom_post_type}.php page is because of the has_archive.
    When has_archive is set on true it will look for archive-{custom_post_type}.php instead of the single page.

    Hope this worked.

  3. It’s a good practice also uses the register_activation_hook() and register_deactivation_hook() when creating new content types.

    It seems that fresh new content types always will fail to be rewritten. To avoid this, put in the register_activation_hook() callback the flush_rewrite_rules() and your registration new content function. I don’t know why, but doing this seems to avoid this problem. Look:

    register_activation_hook( __FILE__, 'your_active_hook' );

function your_active_hook() {
    special_media_post();
    flush_rewrite_rules();
}

  4. I copied your code, flushed the rewrite rules via the Admin and now the Theme uses the right templates when I visit a Media Post.

    You need to flush the rewrite rules once using the after_switch_theme hook. This will make sure that the rewrite rules get flushed automatically after the user has activated the Theme.

    You can use this code (straight from the Codex):

    add_action( 'init', 'theme_prefix_cpt_init' );
function theme_prefix_cpt_init() {
    register_post_type( ... );
}

function theme_prefix_rewrite_flush() {
    flush_rewrite_rules();
}
add_action( 'after_switch_theme', 'theme_prefix_rewrite_flush' );

    Please consult the WordPress Codex for more information: http://codex.wordpress.org/Function_Reference/register_post_type

    EDIT: In such a case, the Inspect Rewrite Rules Plugin comes in very handy, because it allows you to see the rules connected to your custom post type: http://wordpress.org/extend/plugins/rewrite-rules-inspector/

    On a sidenote please also note that the recommended place to put Custom Post Types is a Plugin, not a Theme.
