yii2 Undefined variable in form

Question

When running the code:

return $this->render('update', [
   'model' => $model,
   'stok' => $stok
   ]);

I get an error related to undefined variable:

PHP Notice 'yii\base\ErrorException' with message 'Undefined variable: stok'

My form is as follows:

<div class="col-sm-2">
   <?= $form->field($stok, 'harga_jual1')->textInput(['id' => 'hargaRetail'])->label('Harga Retail') ?>
</div>

How can I resolve this error?

you missed update.php from where _form.php rendered. add 'stok' => $stok there also. — Insane Skull

check it out and follow the render what would be do! controller -> render update.php -> _form.php

readd below in _form.php

return $this->render('_form', [
   'model' => $model,
   'stok' => $stok
]);

You need to check on the update.php, is it already set this block

return $this->render('_form', [
   'model' => $model,
   'stok' => $stok
]);

Usually from actionUpdate controller it's will be render update.php then inside it will be render _form.php, so the $stok variable must be set too in the update.php
