yii2 Class 'app\controllers\AccessControl' not found
一般是命名空间问题, 写成\yii\filters\AccessControl::className(),
yii2想要新增第三方vendor, 修改composer.json,
"require-dev": {
"yiisoft/yii2-codeception": "*",
"yiisoft/yii2-debug": "*",
"yiisoft/yii2-gii": "*",
"zircote/swagger-php": "*",
"yiisoft/yii2-faker": "*"
},
加入了"zircote/swagger-php": "*", 然后运行php composer.phar update发现报错
于是找到解决方案
php composer.phar global require "fxp/composer-asset-plugin:~1.1.1"
然后在php composer.phar update, 不再报错
表单提交改成Ajax形式验证
Controller
if (Yii::$app->request->isAjax) {
Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
return \yii\bootstrap\ActiveForm::validate($model);
}
View
$form = ActiveForm::begin([
'enableAjaxValidation' => true,
]);
Activeform 下拉菜单多选
dropdownList(User::getArrayNoticeTargets(), ['multiple' => 'true', 'size' => 3])
Activeform 生成form是label和input平行样式
use yii\widgets\ActiveForm;
$form = ActiveForm::begin([
'options' => ['class' => 'form-horizontal'],
'fieldConfig' => [
'template' => "{label}{input}\n{error}",
'labelOptions' => ['class' => 'col-md-4'],
'inputOptions' => ['class' => 'col-md-6'],
],
])
或
use yii\bootstrap\ActiveForm;
$form = ActiveForm::begin([
'layout' => 'horizontal',
'fieldConfig' => [ 'template' => "{label}\n{beginWrapper}\n{input}\n{hint}\n{error}\n{endWrapper}", 'horizontalCssClasses' => [ 'label' => 'col-sm-4', 'offset' => 'col-sm-offset-4', 'wrapper' => 'col-sm-8', 'error' => '', 'hint' => '', ], ] ])
