如何解决Yii2 过滤 CRUD 和下拉菜单
我正在尝试学习 Yii2 框架。有人可以帮我解决这个问题，我真的很感激。卡在两件事上，过滤 CRUD 中的数据并在导航栏上的 ('reserveringen) 处添加一个下拉菜单。 Image database names Tafel = Table（翻译）
[Image database names][1]
<?php
/* @var $this \yii\web\View */
/* @var $content string */
use app\widgets\Alert;
use yii\helpers\Html;
use yii\bootstrap\Nav;
use yii\bootstrap\NavBar;
use yii\widgets\Breadcrumbs;
use app\assets\AppAsset;
AppAsset::register($this);
?>
<?php $this->beginPage() ?>
<!DOCTYPE html>
<html lang="<?= Yii::$app->language ?>">
<head>
<meta charset="<?= Yii::$app->charset ?>">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width,initial-scale=1">
<?php $this->registerCsrfMetaTags() ?>
<title><?= Html::encode($this->title) ?></title>
<?php $this->head() ?>
</head>
<body>
<?php $this->beginBody() ?>
<div class="wrap">
<?php
NavBar::begin([
'brandLabel' => Yii::$app->name,'brandUrl' => Yii::$app->homeUrl,'options' => [
'class' => 'my-navbar navbar-fixed-top',],]);
echo Nav::widget([
'options' => ['class' => 'navbar-nav navbar-right'],'items' => [
['label' => 'Home','url' => ['/site/index']],['label' => 'Serveren','url' => ['/overzicht/index' ]], [
'label' => 'Reserveringen', 'items' => [
['label' => 'Reservering weergeven', 'url' => '/reserveringen/index'], ['label' => 'Reservering maken', 'url' => '/reserveringen/create'], ],
['label' => 'Gegevens','url' => ['/eten/index' ]],// ['label' => 'About','url' => ['/site/about']],// ['label' => 'Contact','url' => ['/site/contact']],Yii::$app->user->isGuest ? (
['label' => 'Login','url' => ['/site/login']]
) : (
'<li>'
. Html::beginForm(['/site/logout'],'post')
. Html::submitButton(
'Logout (' . Yii::$app->user->identity->username . ')',['class' => 'btn btn-link logout']
)
. Html::endForm()
. '</li>'
)
],]);
NavBar::end();
?>
<div class="container">
<?= Breadcrumbs::widget([
'links' => isset($this->params['breadcrumbs']) ? $this->params['breadcrumbs'] : [],]) ?>
<?= Alert::widget() ?>
<?= $content ?>
</div>
</div>
<footer class="footer">
<div class="container">
<!-- <p class="pull-right"><?= Yii::powered() ?></p> -->
</div>
</footer>
<?php $this->endBody() ?>
</body>
</html>
<?php $this->endPage() ?>
Another thing I'm stuck at is the option to filter the CRUD by selecting a data Trying to make a select option where the person can filter the table number. 1 to 5. For example when 1 is selected only the datas with table 1 appear.
我遇到的另一件事是通过选择一个数据来过滤 CRUD 的选项 试图做出一个选择选项，人们可以在其中过滤表号。 1 到 5。例如选择 1 时只出现表 1 的数据。
<?php
use yii\helpers\Html;
use yii\grid\GridView;
/* @var $this yii\web\View */
/* @var $searchModel app\models\bestellingSearch */
/* @var $dataProvider yii\data\ActiveDataProvider */
$this->title = 'Bestelling maken';
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="bestelling-index">
<h1><?= Html::encode($this->title) ?></h1>
<p>
<?= Html::a('Maak een bestelling aan',['create'],['class' => 'btn btn-success']) ?>
</p>
<?php $menuSort=[1=>'1',2=>'2',3=>'3',4=>'4',5=>'5'];
?>
<?php // echo $this->render('_search',['model' => $searchModel]); ?>
<?= GridView::widget([
'dataProvider' => $dataProvider,'filterModel' => $searchModel,'columns' => [
['class' => 'yii\grid\SerialColumn'],'ID','Artikel:ntext','Table',[
'attribute'=>'Table','label' => 'Table','filter'=>$menuSort,'contentOptions' => ['style' => 'width:200px; white-space: normal;' ],'format' => 'raw','value' => function ($model) use ($menuSort) { return $menuSort[$model->type];}
],// 'filter'=>$menuSoorten,'Prijs','Totaal',['class' => 'yii\grid\ActionColumn'],]); ?>
</div>
