Warning: Invalid argument supplied for foreach()

You should check that what you are passing to foreach is an array by using the is_array function

If you are not sure it's going to be an array you can always check using the following PHP example code:

if (is_array($variable)) {

  foreach ($variable as $item) {
   //do something
  }
}

This means you have an error in your SQL too since it does not return any data to the foreach as far as I can understand. Make sure that your SQL is correct.
