Using wildcards in prepared statement - MySQLi

Question

I\'m trying to run the following query, and I\'m having trouble with the wildcard.

   function getStudents() {
        global $db;
        $users = array();
         


        

Answer 1

Another way to do this is:

SELECT id, adminRights FROM users 
  WHERE classes LIKE CONCAT("%", ?, "%") && adminRights='student'

This is handy in case you have a dynamic result bind and only want to change the SQL query...
