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',]) ?>
这段代码错了.
所以.我需要得到用户输入的值.然后设置它???
$form-> field()必须有$model,$attribute,$options = [].如何编写不使用$model和$attribute的字段?它不是表列,我需要获取值并设置它而不是???
我试试看
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 $this->redirect(['index']); }
但它引发了一个例外.在$model = $this-> $model的行中,我不知道如何从字段提交id到链接
如果我把它放在浏览器http:// yii2-shop / backend / web / order / add-item中,添加项目是有效的吗?modelid = 13& id = 1& quantity = 4
UPD
现在我的表格看起来像
<?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模型中标记的公共变量.我无法获得表单字段值以将其提交到add-item
解决方法
所以.我解决了这个问题.
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 $quantity; public function rules() { return [ [['modelid','id','quantity'],'integer'],]; } }
我现在编辑了actionUpdate()
public function actionUpdate($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]); ?>
_addItemForm现在包含:
<?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',]) ?> </td> <?PHP ActiveForm::end(); ?>
我不敢相信我自己做了什么.我很高兴没有人帮忙,因为现在我知道的更多了.
