->whereAdd()

Описание

Adds items to the where part of a SQL query. Calling this without any arguments clears the where condition. The default behavior is to add 'AND' to the existing conditions, use the $logic parameter to append OR conditions.

Параметр

• string $cond - condition to add, or blank to reset the conditions

• string $logic - optional logic "OR" (defaults to "AND")
