Yii2 GridView Filtering on Relational Column
To filter a Yii2 GridView by a relational column, you can make use of the joinWith()
method in the query. Here's an example of how you can achieve this:
$query = YourModel::find()->joinWith('relationName');
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
// Apply the filter
$query->andFilterWhere(['related_table.column_name' => $filterValue]);
// Render the GridView
echo GridView::widget([
'dataProvider' => $dataProvider,
'columns' => [
// Specify the columns you want to display
],
]);
Replace YourModel
with the name of your model class, relationName
with the name of the relation you want to join, related_table
with the name of the related table, and column_name
with the name of the column you want to filter.
This should allow you to filter the GridView based on a relational column.
