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
}
