How to limit user to publish post per day and per role?

2 comments

1. You can use my plugin Posts Creation Limits which has a per user, per role, per post type, per post status limiting system and combined with its post_creation_limits_custom_checks action hook and check if the user has created a post that day already – if so: show the the “limit reached message”. For example:

   add_action( 'post_creation_limits_custom_checks', 'post_per_day_limit' );
   
   function post_per_day_limit( $type, $user_id ) {
       global $bapl,$wpdb;
   
       // safe check: Plugin installed?
       ! isset( $bapl ) AND _doing_it_wrong( __FUNCTION__, sprintf( 'You need to %sinstall the needed Plugin%s', '<a href="http://wordpress.org/extend/plugins/bainternet-posts-creation-limits/">', '</a>' ), 0 );
   
       $time_in_days = 1; // 1 means in last day
       $count = $wpdb->get_var(
           $wpdb->prepare("
               SELECT COUNT(*) 
               FROM $wpdb->posts 
               WHERE post_status = 'publish' 
               AND post_type = %s 
               AND post_author = %s
               AND post_date >= DATE_SUB(CURDATE(),INTERVAL %s DAY)",
               $type,
               $user_id,
               $time_in_days
           )
       );
       if ( 0 < $count ) 
           $count = number_format( $count );
   
       // here you can check since we have the $count ex: 
       // limit for 2 posts a day
       if ( 1 < $count ) {
           // return limit reached message using the plugin class
           exit( $bapl->bapl_not_allowed( 'you can not posts more them two posts a day' ) );
       }
       // else do nothing
   }

2. You dont need to rely on

   //Limit posts per month
       $time_in_days = 1; // 1 means in last day
       $count = $wpdb->get_var(
           $wpdb->prepare("
               SELECT COUNT(*) 
               FROM $wpdb->posts 
               WHERE post_status = 'publish' 
               AND post_type = %s 
               AND post_author = %s
               AND post_date >= DATE_SUB(CURDATE(),INTERVAL %s DAY)",
               'post',
               get_current_user_id(),
               $time_in_days
           )
       );
       if ( 0 < $count ) 
       $count = number_format( $count );
   
       // here you can check since we have the $count ex: 
       // limit for 2 posts a day
       if ( 1 < $count ) {
           // return limit reached message using the plugin class
            $errors[] = 'You have reached your monthly post limit';
       }
   

   Where I have $errors is where you can echo a message, in my case I’ plugging into the WP user frontend.

   If you wanted to do it by role than you can simply add another if statement checking if that user has the correct role inside the if ( 1 < $count ) {}, it does then echo your code or run a redirect to an error page.
