所以我有這段代碼：<?= GridView::widget([ 'dataProvider' => $detProvider, //'filterModel' => $searchModel1, if ($detProvider !== null) { 'columns' => [ ['class' => 'yii\grid\SerialColumn'], // 'id', 'first_name', 'last_name', 'email', /*'application_id',*/ [ 'class' => 'yii\grid\ActionColumn', 'template' => '{view}', 'buttons' => [ 'view' => function ($url, $model, $key) { return Yii::$app->user->can('viewApplicant') ? Html::a(Html::tag('span', '', ['class' => "glyphicon glyphicon-eye-open"]), $url, ['title' => Yii::t('yii', 'View')]):""; }, /*'edit' => function ($url, $model, $key) { return Yii::$app->user->can('editApplicant') ? Html::a(Html::tag('span', '', ['class' => "glyphicon glyphicon-pencil"]), $url, ['title' => Yii::t('yii', 'Edit')]):""; }, 'delete' => function ($url, $model, $key) { return Yii::$app->user->can('deleteApplicant') ? Html::a(Html::tag('span', '', ['class' => "glyphicon glyphicon-trash"]), $url, ['title' => Yii::t('yii', 'Delete'), 'data' => ['method' => 'post', 'confirm' => Yii::t('app', 'Are you sure you want to delete this item?'), 'params' => ['id' => $model['id'], '_csrf' => Yii::$app->request->csrfToken]]]):""; },*/ ], 'urlCreator' => function($action, $model, $key, $index) { if ($action === 'view') { $url = 'index.php?r=admin/applicant/view&id=' . $model['id']; return $url; } } ], ], }]); ?>我放置該 if 語句是因為我希望僅當 detProvider 不為 null 時才顯示此特定表。但是我收到一個解析錯誤；ParseError 語法錯誤，意外的“if”（T_IF），期待“]”有人可以幫忙嗎？我究竟做錯了什么？？我還是 yii2 和 php 的新手。

如果您只想在 dataProvider 不為 null 時顯示 gridview，那么您應該以這種方式檢查
<?php
if ($detProvider !== null) {
echo GridView::widget([
'dataProvider' => $detProvider,
//'filterModel' => $searchModel1,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
// 'id',
'first_name',
'last_name',
'email',
/*'application_id',*/
[
'class' => 'yii\grid\ActionColumn',
'template' => '{view}',
'buttons' => [
'view' => function ($url, $model, $key) {
return Yii::$app->user->can('viewApplicant') ? Html::a(Html::tag('span', '', ['class' => "glyphicon glyphicon-eye-open"]), $url, ['title' => Yii::t('yii', 'View')]):"";
},
/*'edit' => function ($url, $model, $key) {
return Yii::$app->user->can('editApplicant') ? Html::a(Html::tag('span', '', ['class' => "glyphicon glyphicon-pencil"]), $url, ['title' => Yii::t('yii', 'Edit')]):"";
},
'delete' => function ($url, $model, $key) {
return Yii::$app->user->can('deleteApplicant') ? Html::a(Html::tag('span', '', ['class' => "glyphicon glyphicon-trash"]), $url, ['title' => Yii::t('yii', 'Delete'), 'data' => ['method' => 'post', 'confirm' => Yii::t('app', 'Are you sure you want to delete this item?'), 'params' => ['id' => $model['id'], '_csrf' => Yii::$app->request->csrfToken]]]):"";
},*/
],
'urlCreator' => function($action, $model, $key, $index) {
if ($action === 'view') {
$url = 'index.php?r=admin/applicant/view&id=' . $model['id'];
return $url;
}
}
],
],
]);
}
?>
