I have been working on a theme template to speed up my work progress lately and custom post types where taking a lot of my time.
These are a few simple functions that may be able to help you
function theme_template_create_post_type( $post_type, $labels = array(), $post_args = array() ) {
if ( !$labels || count( $labels ) < 10 ) {
$labels = array(
'name' => __( ucfirst( $post_type . 's' ) ),
'singular_name' => __( ucfirst( $post_type ) ),
'add_new' => __( 'Add New' ),
'add_new_item' => __( 'Add New' ),
'edit_item' => __( 'Edit ' . ucfirst( $post_type ) ),
'new_item' => __( 'Add New' ),
'view_item' => __( 'View ' . ucfirst( $post_type ) ),
'search_items' => __( 'Search ' . ucfirst( $post_type . 's' ) ),
'not_found' => __( 'No ' . $post_type . 's found' ),
'not_found_in_trash' => __( 'No ' . $post_type . 's found in trash' ),
'all_items' => __( 'All ' . ucfirst( $post_type . 's' ) )
);
}
$default_post_args = array( 'public' => true, 'show_ui' => true, 'capability_type' => 'post', 'hierarchical' => false, 'menu_position' => 20, 'supports' => array( 'title', 'editor', 'thumbnail' ) );
$post_args = wp_parse_args( $post_args, $default_post_args );
$custom_post_args = array(
'labels' => $labels,
'public' => $post_args[ 'public' ],
'show_ui' => $post_args[ 'show_ui' ],
'capability_type' => $post_args[ 'capability_type' ],
'hierarchical' => $post_args[ 'hierarchical' ],
'menu_position' => $post_args[ 'menu_position' ],
'supports' => $post_args[ 'supports' ],
'rewrite' => array( 'slug' => $post_type )
);
register_post_type( $post_type, $custom_post_args );
}
function theme_template_create_updated_messages( $post_type ) {
add_filter( 'post_updated_messages', function( $messages ) use( $post_type ) {
global $post, $post_ID;
$messages[ $post_type ] = array(
0 => '',
1 => sprintf( '%s updated. <a href="https://wordpress.stackexchange.com/questions/62935/%s">View %s</a>', ucfirst( $post_type ), esc_url( get_permalink($post_ID) ), ucfirst( $post_type ) ),
2 => 'Custom field updated.',
3 => 'Custom field deleted.',
4 => sprintf( '%s updated.', ucfirst( $post_type ) ),
5 => isset($_GET['revision']) ? sprintf( '%s restored to revision from %s', ucfirst( $post_type ), wp_post_revision_title( (int) $_GET['revision'], false ) ) : false,
6 => sprintf( '%s published. <a href="https://wordpress.stackexchange.com/questions/62935/%s">View %s</a>', ucfirst( $post_type ), esc_url( get_permalink($post_ID) ), ucfirst( $post_type ) ),
7 => sprintf( '%s saved.', ucfirst( $post_type ) ),
8 => sprintf( '%s submitted. <a target="_blank" href="https://wordpress.stackexchange.com/questions/62935/%s">Preview %s</a>', ucfirst( $post_type ), esc_url( add_query_arg( 'preview', 'true', get_permalink($post_ID) ) ), ucfirst( $post_type ) ),
9 => sprintf( '%3$s scheduled for: <strong>%1$s</strong>. <a target="_blank" href="%2$s">Preview %3$s</a>', date_i18n( 'M j, Y @ G:i', strtotime( $post->post_date ) ), esc_url( get_permalink($post_ID) ), ucfirst( $post_type ) ),
10 => sprintf( '%s draft updated. <a target="_blank" href="https://wordpress.stackexchange.com/questions/62935/%s">Preview %s</a>', ucfirst( $post_type ), esc_url( add_query_arg( 'preview', 'true', get_permalink($post_ID) ) ), ucfirst( $post_type ) ),
);
return $messages;
});
}
function theme_template_create_post_title( $post_type, $post_title ) {
$custom_filter = function( $title ) use( $post_type, $post_title ) {
$screen = get_current_screen();
if ( $post_type == $screen->post_type ) {
$title = $post_title;
}
return $title;
};
add_filter( 'enter_title_here', $custom_filter );
}
You can call them like this:
/*
* Custom post type [ slide ]
*/
add_action( 'init', function() {
theme_template_create_post_type( 'slide', array(), array( 'public' => false, 'supports' => array( 'title', 'editor' ) ) );
theme_template_create_updated_messages( 'slide' );
theme_template_create_post_title( 'slide', 'Enter slide name here' );
});
Note you will require PHP Version 5.3.0 to use the anonymous function approach.
As for meta boxes I tend not to go into the code-first approach as I have been there and done that and encountered a lot of errors/troubles on my way. (Again I am not the best WordPress developer in the world so forgive me)
I use something called Advanced Custom Fields found here: http://wordpress.org/extend/plugins/advanced-custom-fields/ the free version (no plugins) does everything I ask and it already includes many features I need! (Along with looking really nice too)
Hope this helps 🙂
