Unsupported operand types error / Carriage return - PHP

Question

I am working with Moodle 2.2.1 but have a basic php-mysql problem. I am trying to return a count of a field with a condition in my WHERE clause. The WHERE clause condition is coming from a foreach loop.This is my code:

    foreach($allunits as $allunit)
    {
     $countquery = $DB->get_records_sql("SELECT COUNT(uid.userid) FROM {user_info_data} uid WHERE uid.data = '".$allunit."' OR uid.data = '".$allunit."\r'");
     $ucount = $ucount + $countquery;       
    }

This throws an unsupported operand types error. Since the 'data' field can have junk lines/spaces added to it I need to use \r to search for such values. If i directly pass the value in wHERE clause it works fine, like this,

    SELECT COUNT(uid.data) FROM {user_info_data} WHERE uid.data = 'Marketing' OR uid.data = 'Marketing\r'

but my wHERE clause value needs to come from an array.

Can any one help me out with this problem?

Thanks

EDIT: a var_dump of my array '$allunits'

Answer 1

You are passing a literal carriage return, instead of the string \r which is what is required. This is because your string is enclosed in double quotes and PHP is interpreting the escape sequence before it is passed to MySQL.

The solution is simple - either enclose your SQL string in single quotes, or even simpler, escape the backslash with another backslash:

$countquery = $DB->get_records_sql("SELECT COUNT(uid.userid) FROM {user_info_data} uid WHERE uid.data = '".$allunit."' OR uid.data = '".$allunit."\\r'");

EDIT

I think this will do what you want in a single query with no looping:

$query = "
  SELECT COUNT(uid.data) AS users
  FROM {user_info_data}
  WHERE uid.data IN ('".implode("','", $allunits)."','".implode("\\r','", $allunits)."\\r')
";
$countquery = $DB->get_records_sql($query);
$ucount = $countquery->users;
