yii2 CRUD ActiveForm does not send id to Update action - yii2

Question

I am trying to update data but when i click on the submit button all i get is Bad request (#400) missing required parameter: id. It was working on the previous project and all the files are created by Gii CRUD. I have the same issue when i am trying to create data but guess i am making same mistake with it. What is wrong? What i am doing wrong?Thank you in advance!

Answer 1

public function actionUpdate($id) {
This action expects a required parameter $id when it's called but you're not passing it (it goes something like index.php?r=site/update but it should be like this: index.php?r=site/update&id=10). Solution to that problem is to add the following line to ActiveForm parameters:
'action' => Url::to(['site/update', 'id' => $id]),
Where $id is the ID of the model. And this makes:
<?php
$form = ActiveForm::begin([
'id' => 'update-form',
'action' => Url::to(['site/update', 'id' => $id]),
]); ?>
Sorry in advance if this is defined somewhere else, I haven't look at a whole code.
