yii2 表單 $form

<?= $form->field($userRole, 'userid', ['options' =>['class' => 'bigDiv'] ])->textInput(['placeholder'=> 'ccc', 'class'=> 'inputSelf', 'maxlength' => true, 'value' => $user->id]) ?>

 

 

<?php

 $form = ActiveForm::begin(['action' => ['sykc','id' => $model->id],
                 'method'=>'post',
                 'options' => ['id'=>'w-sykc-form','enctype' => 'multipart/form-data','autocomplete'=>"off",'data-pjax'=>'true'],
                 'fieldConfig' => [
                     'template' => '{label}<div class="col-lg-5">{input}</div><div class="col-lg-3">{error}</div>',
                     'labelOptions' => ['class' => 'col-sm-2 control-label'],  //修改label的樣式
  ] ]);
?>

<?= $form->field($model, 'username')->textInput(['placeholder' => '您的姓名', 'require' => 'true','class' => 'form-control ', 'maxlength' => 255])->label(false) ?> 

<?= $form->field($model, 'email')->textInput(['placeholder' => '您的郵箱地址', 'require' => 'true', 'class' => 'form-control', 'maxlength' => 255])->label(false) ?>

<?= $form->field($model,'grade_id')->dropDownList($grades,['prompt'=>'選擇年級'])?>

<?= Html::activeDropDownList($model, 's_id',  ArrayHelper::map(Standard::find()->all(), 's_id', 'name')) ?>

<div class="form-group"> 　　<?= Html::submitButton('提交', ['class' => 'btn btn-blue-bg-new']) ?> 　　<div class="help-block"></div> </div> <?php ActiveForm::end(); ?>

 

　　

 

$model = new Form;
        $model->scenario = 'dingyue';
        if($model->load(Yii::$app->request->post())){
            if(Yii::$app->request->isAjax){
                Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
                return ActiveForm::validate($model);
            }else{
                if ($model->save()) {
                    $this->flash('success',  '提交成功!');
                    return $this->redirect(Yii::$app->request->referrer);
                } else {
                    $this->flash('error', Yii::t('easyii', 'Create error. {0}', $model->formatErrors()));
                    return $this->refresh();
                }
            }

        }

　　這樣寫完后會在系統的session中存一個success或者是error的信息，如果不做下面操作，那么呈現的效果表單提交，頁面刷新

　　這時候用戶無法知道自己是否已經提交成功或者失敗，需要在頁面增加一塊代碼

<script>
    <?php foreach(Yii::$app->session->getAllFlashes() as $key => $message) : ?>
    alert('<?=$message?>');
    <?php endforeach; ?>
</script>

　　以上5行代碼的意思是：如果后台設置了flash，那么前台頁面就把提示的信息alert出來

 

$form = ActiveForm::begin(['action' => ['sykc','id' => $model->id],
                'method'=>'post',
                'options' => ['id'=>'w-sykc-form','enctype' => 'multipart/form-data','autocomplete'=>"off",'data-pjax'=>'true'],
                'fieldConfig' => [
                    'template' => '{label}<div class="col-lg-5">{input}</div><div class="col-lg-3">{error}</div>',
                    'labelOptions' => ['class' => 'col-sm-2 control-label'],  //修改label的樣式
                ]
        ]);

 

 

 

<?=Html::activeHiddenInput($model,'address')?>
