wpuseraccount

Thank you.

I am very grateful to Namita and Subharanjan.

[Bainternet Posts Creation Limits] is very good.
This limits the post per day.
But, this does not limit the post per hour or forever.

I’ve tried the following methods.
If possible, I want to check this.

What good does the admin_head-post-new.php is use ?
Is the SQL wrong ?

Please, I want to check.
I’m sorry about I can only do a little English.

———- functions.php ———-

add_action( 'admin_head-post-new.php', 'check_post_limit' );
function check_post_limit() {
  if( $_GET['post_type'] === 'item' ) {
    global $userdata;
    global $wpdb;
    $item_count = $wpdb->get_var( "SELECT count(*) FROM $wpdb->posts WHERE post_status = 'publish' AND post_type = 'item' AND post_author = $userdata->ID" );
    if( $item_count >= 12 ) { wp_die( "error" ); }
  } elseif( $_GET['post_type'] === 'shopinfo' ) {
    global $userdata;
    global $wpdb;
    $shopinfo_count = $wpdb->get_var( "SELECT count(*) FROM $wpdb->posts WHERE post_status = 'publish' AND post_type = 'shopinfo' AND post_author = $userdata->ID" );
    if( $item_count >= 1 ) { wp_die( "error" ); }
  } elseif( $_GET['post_type'] === 'news' ) {
    global $userdata;
    global $wpdb;
    $today = date( 'Y-m-d 00:00:00', ( gmmktime() );
    $news_count = $wpdb->get_var( "SELECT count(*) FROM $wpdb->posts WHERE post_status = 'publish' AND post_type = 'news' AND post_author = $userdata->ID AND post_modified > '$today'" );
    if( $news_count >= 10 ) { wp_die( "error" ); ]
  }
}
