在yii2框架中使用动态模型时如何设置属性标签?
下面是我的代码:$model = DynamicModel::validateData(compact('name','shipping'), [
[['name','shipping'], 'required'],
]);
if ($model->hasErrors()) {
// validation fails
// }
} else {
//validation true
}
作为一种简单的方法，只需为所需的属性设置单独的验证消息:
$model = DynamicModel::validateData(compact('name','shipping'), [
[['name'], 'required', ['message' => Yii::t('app', 'Name is required for this form.')]],
[['name'], 'required', ['message' => Yii::t('app', 'Shipping address is required for this form.')]],
]);
并在输出DynamicModel字段时使用标签:
echo $form->field($model, 'name')->textInput()->label(Yii::t('app', 'Name'));
echo $form->field($model, 'name')->textInput()->label(Yii::t('app', 'Shipping address'));
我喜欢扩展组件，像这样:
class DynamicModel extends 'yii'base'DynamicModel {
protected $_labels;
public function setAttributeLabels($labels){
$this->_labels = $labels;
}
public function getAttributeLabel($name){
return $this->_labels[$name] ?? $name;
}
}
和，使用它:
$attributes = ['name'=>'John','email'=>'john@mailinator.com'];
$model = new DynamicModel($attributes);
$model->setAttributeLabels(['name'=>'Name','email'=>'E-mail']);
$model->validate();
例如:
public function attributeLabels()
{
return [
'id' => Yii::t('app', 'ID'),
'first_name' => Yii::t('app', 'First Name'),
];
}
