更新方案中文件上载的验证规则

Question

I have file upload option in form. I have added field in model and added vlaidation rules as below.

[['file1'], 'file', 'skipOnEmpty' => false, 'extensions' => 'pdf,png,jpg', 'maxSize' => "10485760", 'tooBig' => "Maximum upload file size is 10MB"]

In edit mode, file field is not required. So I need to skip required field validation for update scenario but if user choose a file in update form, then extension, size need to be validated.

I changed rule as below.

[['file1'], 'file', 'skipOnEmpty' => false, 'extensions' => 'pdf,png,jpg', 'maxSize' => "10485760", 'tooBig' => "Maximum upload file size is 10MB", "on" => ["insert"]], 

[['file1'], 'file', 'skipOnEmpty' => true, 'extensions' => 'pdf,png,jpg', 'maxSize' => "10485760", 'tooBig' => "Maximum upload file size is 10MB", "on" => ["update"]], 

But it is still asking upload a file in edit form.

Thanks

try below rules

[['file1'], 'file', 'skipOnEmpty' => true, 'extensions' => 'pdf,png,jpg', 'maxSize' => "10485760", 'tooBig' => "Maximum upload file size is 10MB"],
[['file1'], 'required', 'on' => 'insert'],

add scenario in your create action not in update

$model->scenario = 'insert';
