Cakephp 2.x在没有模型的控制器中设置自定义验证消息

Question

Code in View

<?= $this->Form->input('ProductGroupImage.image', array("class" => "", "type" => "file")); ?>

Here ProductGroupImage is just alias not a actual model.

In Controller

$this->validationErrors['ProductGroupImage']['image'] = "File not Valid"

Above Code does not show Error message in view.

Answer 1

i assume that you are triggering the validation on model and then you updating your validationErrors array.

if (!$this->ProductGroupImage->validates()) {
    $errors = $this->ProductGroupImage->validationErrors;
}

You can then update the errors variable and the reassign it to the validationErrors.

if (isset($this->ProductGroupImage->validationErrors['execused_referral_by'])) {
$errors['execused_referral_by'] = "Please Select Excused By";
}

$this->Tardy->validationErrors = $errors;
