我如何获得 form->field() 值?
How can i get form->field() value?
简而言之,我有以下代码:
<?= $form->field( $isntmodel, 'id')->textInput() ?>
<?= Html::a('<i class="mdi-action-done"></i>', ['add-item', 'id' => ???], [
'class' => 'btn-btn-add pull-right',
]) ?>
此代码错误。
所以。我需要获取用户输入的值。并将其设置为 ???
$form->field()
必须有 $model, $attribute, $options = []
。如何不使用 $model 和 $attribute 来编写字段?它不是 table 列,我只需要获取值并将其设置为 ???
我试试
public function actionAddItem($id) {
$model = $this->$model;
$product = Product::findOne($id);
$orderItem = new OrderItem();
$orderItem->order_id = $model->id;
$orderItem->title = $product->title;
$orderItem->price = $product->getPrice();
$orderItem->product_id = $product->id;
$orderItem->save();
return $this->redirect(['index']);
}
但是它抛出了一个异常。在 $model = $this->$model
行,我不知道如何从字段提交 id 到 link
如果我把它放在浏览器中,添加项目就可以了http://yii2-shop/backend/web/order/add-item?modelid=13&id=1&quantity=4
UPD
现在我的表单看起来像
<?php $form = ActiveForm::begin([]); ?>
<tr>
<td><?= $n ?></td>
<td><?= $form->field( $model, 'newOrderItemId')->textInput()->label(false) ?></td>
<td></td>
<td></td>
<td class="text-center"><?= $form->field( $model, 'newOrderItemQuantity')->textInput()->label(false) ?></td>
<td>
<?= Html::a('<i class="mdi-action-done"></i>', [
'/order/add-item',
'modelid' => $model->id,
'id' => $model->newOrderItemId,
'quantity' => $model->newOrderItemQuantity,
], [
'class' => 'btn btn-add pull-right',
'data-toggle'=>'tooltip' ,
'data-placement'=>'bottom',
'title'=>'Добавить товар',
]) ?>
</td>
</tr>
<?php ActiveForm::end(); ?>
而且add-item
看起来像
public function actionAddItem($modelid, $id, $quantity) {
$model = $this->findModel($modelid);
$product = Product::findOne($id);
$orderItem = new OrderItem();
$orderItem->order_id = $model->id;
$orderItem->title = $product->title;
$orderItem->price = $product->getPrice();
$orderItem->product_id = $product->id;
$orderItem->quantity = $quantity;
$orderItem->save();
return $this->redirect(['index']);
}
newOrderItemId
和 newOrderItemQuantity
只是我在 Order
模型中标记的 public 变量。我无法获取提交给 add-item
的表单字段值
所以。我解决了问题。
我为公告变量创建了 AddOrderItem
模型
<?php namespace backend\models;
use yii\base\Model;
class AddOrderItem extends Model {
public $modelid;
public $id;
public $quantity;
public function rules() {
return [
[['modelid','id','quantity'], 'integer'],
];
}
}
然后我编辑了 actionUpdate()
现在看起来像
public function actionUpdate($id) {
$model = $this->findModel($id);
$addOrderModel = new AddOrderItem();
if ($addOrderModel->load(Yii::$app->request->post())) {
$product = Product::findOne($addOrderModel->id);
$orderItem = new OrderItem();
$orderItem->order_id = $model->id;
$orderItem->title = $product->title;
$orderItem->price = $product->getPrice();
$orderItem->product_id = $product->id;
$orderItem->quantity = $addOrderModel->quantity;
$orderItem->save();
return $this->redirect(['view', 'id' => $model->id]);
}
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('update', [
'model' => $model,
'addOrderModel' => $addOrderModel
]);
}
}
在 views/order/update
我添加了以下行
<?= $this->render('_addItemForm', ['model' => $addOrderModel]); ?>
并且 _addItemForm
现在包含这个:
<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
$form = ActiveForm::begin(); ?>
<td><?= $form->field( $model , 'id')->textInput()->label(false) ?></td>
<td></td>
<td></td>
<td class="text-center"><?= $form->field( $model , 'quantity')->textInput()->label(false) ?></td>
<td>
<?= Html::submitButton('<i class="mdi-action-done"></i>',[
'class' => 'btn btn-add pull-right',
'data-toggle'=>'tooltip' ,
'data-placement'=>'bottom',
'title'=>'Добавить товар',
]) ?>
</td>
<?php ActiveForm::end(); ?>
我简直不敢相信这是我自己做的。我很高兴没有人可以提供帮助,因为现在我知道的更多了。
