Property Details
Maps filtering condition keywords to build methods. These methods are used by buildCondition() to build the actual filtering conditions. Particular condition builder can be specified using a PHP callback. For example:
[
'XOR' => function (string $operator, mixed $condition) {
//return array;
},
'LIKE' => function (string $operator, mixed $condition, string $attribute) {
//return array;
},
]
public array $conditionBuilders = ['AND' => 'buildConjunctionCondition', 'OR' => 'buildConjunctionCondition', 'NOT' => 'buildBlockCondition', '<' => 'buildOperatorCondition', '>' => 'buildOperatorCondition', '<=' => 'buildOperatorCondition', '>=' => 'buildOperatorCondition', '=' => 'buildOperatorCondition', '!=' => 'buildOperatorCondition', 'IN' => 'buildOperatorCondition', 'NOT IN' => 'buildOperatorCondition', 'LIKE' => 'buildOperatorCondition']
Map filtering operators to operators used in yii\db\QueryInterface::where().
The format is: [filterOperator => queryOperator].
If particular operator keyword does not appear in the map, it will be used as is.
Usually the map can be left empty as filter operator names are consistent with the ones used in yii\db\QueryInterface::where(). However, you may want to adjust it in some special cases. For example, when using PosgreSQL you may want to setup the following map:
[
'LIKE' => 'ILIKE'
]
