sorry for my dumb question. This My SiteController.
public function actionIndex()
{
$searchModel = new MahasiswaSearch();
$dataProvider = $searchModel->search($this->request->queryParams);
return $this->render('index', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
this my form _search
<div class="control control-expanded">
<?php $form = ActiveForm::begin([
'action' => ['index'],
'method' => 'get',
]); ?>
<?php // echo $form->field($model, 'id') ?>
<?= $form->field($model, 'nim', [
'inputOptions' => ['autofocus' => 'autofocus', 'class' => 'input' ,'required'=>true]
])->input('nim', ['placeholder' => "Nomor Induk Mahasiswa"])->label(false); ?>
</div>
<div class="control control-expanded">
<?= Html::submitButton('Cari', ['class' => 'button button-primary button-block']) ?>
</div>
there is my index.php
<?php $dataes = $dataProvider->models[0]->nim;if ($dataes=="") { ?>
<?php } else {?>
<div class="hero-copy hero-2" style="z-index:30;background-color: rgba(56, 76, 76, 0.5);padding-top:8px; margin-top:8px;">
<p class="hero-paragraph is-revealing" style="text-align:center;">PENGUKUHAN MAHASISWA BARU</p>
<?php
echo "<p style=padding-left:10px;> NIM : " . $dataProvider->models[0]->nim ;echo " </p> \n";
echo "<p style=padding-left:10px;> NAMA : " . $dataProvider->models[0]->nama ;echo " </p> \n";
echo "<p style=padding-left:10px;> ANGKATAN : " . $dataProvider->models[0]->angkatan ;echo " </p> \n";
echo "<p style=padding-left:10px;> PRODI : " . $dataProvider->models[0]->prodi ;echo " </p> \n";
echo "<p style=padding-left:10px;> LOKASI KEGIATAN : " . $dataProvider->models[0]->ruangan ;echo " </p> \n";
}
