How can I remove the "Add New" button in my custom post type?

Question

I have many custom post types that need the Add [custom post type] feature but I have a custom post type of "About" and I do not need to "Add New" about to the about custom post type. So I want to remove the button on top that says "Add About"

This is what I mean:

Any idea how I can remove that?

Answer 1

Please refer below :

function disable_new_posts() {
    // Hide sidebar link
    global $submenu;
    unset($submenu['edit.php?post_type=CUSTOM_POST_TYPE'][10]);

    // Hide link on listing page
    if (isset($_GET['post_type']) && $_GET['post_type'] == 'CUSTOM_POST_TYPE') {
        echo '<style type="text/css">
        #favorite-actions, .add-new-h2, .tablenav { display:none; }
        </style>';
    }
}
add_action('admin_menu', 'disable_new_posts');

A prettier solution would be to disable the capability of creating a custom_post_type:

Simply pass the the parameter 'create_posts' => 'do_not_allow', in the capabilities array when calling register_post_type.

$args = array(
        'label'               => __( 'Custom Post Type', 'text_domain' ),
        'description'         => __( 'Custom Post Type', 'text_domain' ),
        'labels'              => $labels,
        'supports'            => array( ),
        'hierarchical'        => false,
        'public'              => true,
        'show_ui'             => true,
        'show_in_menu'        => true,
        'show_in_nav_menus'   => true,
        'show_in_admin_bar'   => true,
        'has_archive'         => true,
        'exclude_from_search' => false,
        'publicly_queryable'  => true,
        'map_meta_cap'        => true,
        'capabilities' => array(
            'create_posts' => 'do_not_allow'
        )
    );
    register_post_type( 'custom_post_type', $args );

Answer 3

Then, if you just want to remove Add New and you are not using custom_post_type, you should't use 'capability_type' => 'custom_post_type'. You'd better to remove this code. Good luck :)

So, the demo is below:

array(
'labels' => $member_labels,
'has_archive' => true,
'public' => true,
'hierarchical' => true, // like page
'rewrite' => array('slug' => 'member_pages'),
'supports' => array(
    'title',
    'editor',
    'excerpt',
    'custom-fields',
    'thumbnail',
    'page-attributes',
),
'taxonomies' => array('post_tag', 'cm_club'),
// 'capability_type' => 'custom_post_type',
'capabilities' => array(
    'create_posts' => false,
),
'map_meta_cap' => true,
)

Answer 4

Edited @TompaLompa's answer as it was incomplete. Adding create_posts => false won't work if map_meta_cap is not set to true.

Not setting this parameter (or setting it to false) will disable editing of the post type too. This is because you would need to add edit_post capability to each user role in order to add AND edit your post type.

Setting this parameter will use WP internal default meta capability handling and make it work for you if you don't need more finer control over role capabilities then the default WP ones.

Best way i felt is install add-admin-javascript plugin and activate it then go to settings and add javascript write this code in last box

$('.wrap .wp-heading-inline').remove();
$('.wrap .page-title-action').remove();
$('#wp-admin-bar-new-content').remove();
