How to add Extra Column of post Status in All post page

Question

how can I add an extra admin column with the Status of posts like Below Image. i know admin column plugin for this work but i don't want to use any plugin..so please suggest me if there any code to add an extra admin column with the Post Status

Answer 1

The last function doesn't work. Use this instead to fill the status column:

// Add the data to the post columns:
add_action( 'manage_post_posts_custom_column' , 'custom_post_column', 10, 2 );
function custom_post_column( $column, $post_id ) {
    if ( $column == "status" ) {
        echo get_post_status($post_id);
    }
}

Answer 2

This is the simplest use of adding custom columns:

// Add the custom columns to the post type:
add_filter( 'manage_post_posts_columns', 'set_custom_edit_book_columns' );
function set_custom_edit_book_columns($columns) {
    $columns['status'] = __( 'Status', 'your_text_domain' );  // or simply "Status";
    return $columns;
}

// Add the data to the post columns:
add_action( 'manage_post_posts_custom_column' , 'custom_post_column', 10, 2 );
function custom_post_column( $column, $post_id ) {
    if ( $column == "status" ) {
               $p_status = get_post_meta($post->ID, 'status', true);
                echo $p_publish;
    }
}

Of course you could also do this column sortable and so on! Not tested, but it should work, you've got the point
