function my_manage_columns( $columns ) { unset($columns[‘date’]); return $columns; } function my_column_init() { add_filter( ‘manage_posts_columns’ , ‘my_manage_columns’ ); } add_action( ‘admin_init’ , ‘my_column_init’ );
In case anyone else stumbles across this old question like I just did, it looks like the best way to handle this is using metadata_exists() see https://developer.wordpress.org/reference/functions/metadata_exists/ Here’s what the syntax would be for post meta: metadata_exists(‘post’, $post_id, ‘meta_key_to_check’);
You can use the following instead, if (is_singular(‘post’)) { //your code here… } Where by is_singular is the WordPress API conditional function for testing for the existence of a post type. You can also pass an array of post types if you wish. http://codex.wordpress.org/Function_Reference/is_singular

UPDATE 21-01-2016 19:35 SA TIME – BUG FOUND!!!!! YEAH!!!!!! I finally found the bug. As you stated in your last update, the failure only happens when $post_content has a <!–nextpage–> tag in the content. I tested it, and did confirm that any other page after the page after the <!–nextpage–> returns a 404 and then … Read more
Updating the posts $all_posts = get_posts( ‘posts_per_page’ => -1, ‘post_type’ => ‘post’ ); foreach ( $all_posts as $single ) { wp_update_post( array( ‘ID’ => $single->ID, ‘post_title’ => to_title_case( $single->post_title ) // see function below )); } Converting a string to “Title Case” And, while not pertinent to WP, for the sake of completeness: function to_title_case( … Read more

This requires PHP 5.3+ (WP requires PHP 5.2.4+) add_filter(‘get_the_excerpt’, ‘end_with_sentence’); function end_with_sentence($excerpt) { $allowed_end = array(‘.’, ‘!’, ‘?’, ‘…’); $exc = explode( ‘ ‘, $excerpt ); $found = false; $last=””; while ( ! $found && ! empty($exc) ) { $last = array_pop($exc); $end = strrev( $last ); $found = in_array( $end{0}, $allowed_end ); } return … Read more
I don’t think there exist one, but you could create your own, wpse_empty_trash, with something like this: /** * Add a custom hook ‘wpse_empty_trash’ */ add_action( ‘load-edit.php’, function() { add_action( ‘before_delete_post’, function ( $post_id ) { if ( ‘trash’ === get_post_status( $post_id ) && filter_input( INPUT_GET, ‘delete_all’ ) && 1 === did_action( ‘before_delete_post ‘ ) … Read more
