我在 yii2 中的可搜索下拉列表不起作用

Question

yii2 开发人员，我是 yii2 的新手，所以我做了一个下拉搜索，当我从下拉列表中选择数据并点击显示“未找到结果”的搜索按钮时，我想搜索账单月份但是当我使用输入字段进行搜索时，它可以完美运行。

Answer 1

您的选择必须是：

<?= $form->field($model, 'billing_months')->dropDownList( ArrayHelper::map(bill::find()->all(),'billing_months', 'billing_months'), ['prompt'=>'Select Tenure'])?>

您的数据库中有string 字段，而不是integer，因此您的选项值和文本必须使用字符串数据设置。

在BillSearch 中也修正你关于billing_months 的规则，例如：

['billing_months', 'safe']

编辑：您还需要groupBy 以避免重复：

bill::find()->groupBy('billing_months')->all()
