# Return true if data is empty function.

 * I am trying to create a function that will draw data from the database and check
   if the row is empty. If the function is empty, continue.. If !empty, do not display
   anything. I know there is many ways to do this. But I am trying to create less
   code and structure it a little neater.
    Here is my example.
 *     ```
       function check_if_blocked(){
       global $wpdb;
       $results = $wpdb->get_results("SELECT * FROM 'mytable' WHERE user = $user");
       if(empty($resuts)){
          $var = false;
        } else {
          $var = true;
        }
       return $var
       }
   
       function msg_form(){
        if(check_if_blocked()){
         // do stuff if user is not blocked
         // If user is blocked, do not display code
        }
       }
       ```

 * Try something like this:
 *     ```
       function check_if_blocked(){
         global $wpdb;
         return $wpdb->get_results("SELECT * FROM 'mytable' WHERE user = $user");
       }
       ```
   
 *     ```
       function msg_form(){
         if( ! empty( check_if_blocked() ) {
         // do stuff
       } else {
         // don't do stuff
       }
       ```
