Hello,
i have an ActiveForm in which I can edit 2 rows of the same model, the labels are hidden because they are displayed in a table and the label is in the first column.
If there is an error, the message is in both rows the same. How can I change this?
->label("Stückzahl ".$jahr);
only changes the name of the label, but not the text in the error-message.
I would like to show an image of the problem, but attachments didn’t work and I can’t post an URL because this is my first post 
You need change this in the model
public function rules()
{
return [
['image', 'required','message'=>'It is required'],
];
}
This is for if it is required, but you could put your function, for example:
public function rules()
{
return [
['image', 'validateImage',]
];
}
public function validateImage($attribute, $params)
{
if (...) {
$this->addError($attribute, 'Incorrect image.');
}
}
}
In the images I use this :
public function rules()
{
return [['file', 'file','skipOnEmpty' => false,
'uploadRequired' => '', //Error
'maxSize' => 1024*1024*1, //1 MB
'tooBig' => '', //Error
'minSize' => 10, //10 Bytes
'tooSmall' => '', //Error
'maxFiles' => 10,
'tooMany' => '', //Error
],];
}
but I think that you dont want this
The errors are for each atribute in the model, if you have two attributes in the model you have two errors,two validations differents ,
you can change all labels for the atributes in the model:
public function attributeLabels()
{
return [
'image' => 'The image',
'name' => 'The name',
];
}
Thanks, but this is not the problem.
This is my problem, that in each row apples, bananas or oranges is a duplicate. I’d like to have „Apples 2015“ or sth like that. 
Now I have looked into ActiveField.php:
$this->parts['{error}'] = Html::error($this->model, $this->attribute, $options);
So I think it’s only possible when editing $this->attribute…
