Inserting multiple rows (single query) to MySQL in PHP: Prepare-Execute vs. Prepare-Bind-Execute
php,mysql,pdo,prepared-statement,prepare
You can't $connect->bindParam($key+1,$ins);. Because PDO object doesn't have such method. Only PDOStatement has. That is why you've got error message. You should : $query->bindValue($key+1,$ins); And you should use bindValue because if not, all your inserted values will get same value (the last one of $ins before you call execute)....
