string$field
string$dir
string$start
string$end
bool$sort

◆ addTitleInfo()

◆ addWhere()

ApiQueryBase::addWhere (   $value)
protected

Clauses can be formatted as 'foo=bar' or [ 'foo' => 'bar' ], the latter only works if the value is a constant (i.e. not another field)

If $value is an empty array, this function does nothing.

For example, [ 'foo=bar', 'baz' => 3, 'bla' => 'foo' ] translates to "foo=bar AND baz='3' AND bla='foo'"

Parameters
string | array$value
