是的，我有一个数据库表，其中包含案例的详细信息。
现在用户希望能够通过名称，年份，判断数据等来搜索这些案例。
现在我有一个工作示例，但是只有在名称字段中按名称和年份字段中的年份搜索时才有效。例如，您无法在年份字段中搜索名称。
所以我希望有一个主搜索字段，您可以输入任何字符串，它将从搜索字词与任何列相关的数据库中产生一行。
控制器：
public function actionIndex()
{
$model = new Cases;
$searchModel = new CaseSearch();// This is the data to be displayed in gridview
$newsearchModel = new CaseSearch();
$mainCategory = Category::find()->all();// This is grabing the first category list to populate first drop down
$dataProvider = $newsearchModel->search(Yii::$app->request->queryParams);// This is the filter options for the gridview
$request = Yii::$app->request;
$post = $request->post();//$post now takes place of normal $_POST array;
/*
* This deals with the post values when the drop down lists are chosen and submitted via POST
*/
if($newsearchModel->load(Yii::$app->request->post())){
$count = Yii::$app->db->createCommand('SELECT COUNT(*) FROM cases')->queryScalar();
$dataProvider = new SqlDataProvider([
'sql' => 'SELECT * FROM cases',
'totalCount' => $count,
'sort' => [
'attributes' => [
'case_id',
'name',
/*'name' => [
'asc' => ['first_name' => SORT_ASC, 'last_name' => SORT_ASC],
'desc' => ['first_name' => SORT_DESC, 'last_name' => SORT_DESC],

'label' => 'Name',
],*/
],
],
'pagination' => [
'pageSize' => 20,
],
]);
// get the user records in the current page
$models = $dataProvider->getModels();
//This now renders the index page with new set of filters corresponding to the categories picked.
// Also sends back the first category_id to auto populate first category.
return $this->render('index', [
'searchModel' => $searchModel,
'newsearchModel' => $newsearchModel,

现在搜索表单在这里呈现

<?php $form = ActiveForm::begin([

'method' => 'get',
]); ?>
<?= $form->field($newsearchModel, 'mainSearch') ?>
<?= $form->field($newsearchModel, 'name') ?>
<?= $form->field($newsearchModel, 'judgement_date') ?>
<?= $form->field($newsearchModel, 'year') ?>

<?= Html::submitButton('Search', ['class' => 'btn btn-primary']) ?>
<?= Html::resetButton('Reset', ['class' => 'btn btn-default']) ?>
</div>
<?php ActiveForm::end(); ?>
因此，当您搜索mainSearch时，我希望它使用任何与其相关的记录来填充列表视图中的数据
