当我提交表格时,帖子数据显示以下内容:

a:3:{i:0;s:6:"City A";i:1;s:6:"City B";i:2;s:6:"City C";}
But I don't know how to modify data before save function in Yii2. 但我不知道如何在Yii2中保存功能之前修改数据。 Followin is my code:
Followin是我的代码:
if(Yii::$app->request->post()){
$_POST['Adpackage']['Page'] = serialize($_POST['Adpackage']['Page']);
$_POST['Adpackage']['fixer_type'] = serialize($_POST['Adpackage']['fixer_type']);
}
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model
]);
}
Please help me. 请帮我。
Thanks all for your effort. 谢谢你的努力。 I have solved the issue.
我已经解决了这个问题。 here is the code :
这是代码:
public function beforeSave($insert)
{
if (parent::beforeSave($insert)) {
$this->Page = serialize($_POST['Adpackage']['Page']);
$this->fixer_type = serialize($_POST['Adpackage']['fixer_type']);
return true;
} else {
return false;
}
}
Just put this code in model and its working 只需将此代码放入模型及其工作中即可
It's because Yii::$app->request->post()
is different than $_POST
at this stage. 这是因为在这个阶段
Yii::$app->request->post()
与$_POST
不同。 Try to change your code to: 尝试将您的代码更改为:
$post = Yii::$app->request->post();
$post['Adpackage']['Page'] = serialize($post['Adpackage']['Page']);
$post['Adpackage']['fixer_type'] = serialize($post['Adpackage']['fixer_type']);
$model->load($post);
Update: 更新:
Also it would be better to do it on ActiveRecord beforeSave()
method. 最好在ActiveRecord
beforeSave()
方法上执行此操作。
