Yii2 >如何将 _form 视图的 html 输出存储到字符串变量中 [英] Yii2 > How to store html output of a _form view into a string variable

问题描述

我想将使用 ActiveForm 和 Html Helper 的表单视图呈现的 html 输出存储到我的控制器中的一个变量中.

我试过将 renderPartial 的结果直接存储到一个变量中，但没有用:

$htmlform = Yii::$app->controller->renderPartial('_form', ['model' => $model]);

我还尝试使用输出缓冲将输出回显到变量中，但我无法存储输出:

ob_start();echo Yii::$app->controller->renderPartial('_form', ['model' => $model]);$htmlform = ob_get_contents();ob_end_clean();

查看文件:_form.php

<div class="epic-form"><?php $form = ActiveForm::begin();?><?= $form->field($model, 'closed')->textInput() ?><?= $form->field($model, 'title')->textInput(['maxlength' => true]) ?><?= $form->field($model, 'organizationid')->textInput() ?><div class="form-group"><?= Html::submitButton($model->isNewRecord ? Yii::t('app', 'Create') : Yii::t('app', 'Update'), ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>

<?php ActiveForm::end();?>

如果有人想出一个很棒的解决方案..

解决方案

我已经在一个简单的 ControllerAction 中尝试过这种方式并且工作正常......在 var_dump($test) 那里得到了切面的结果

公共函数actionView($id){$test = $this->renderPartial('_form', ['模型' =>$this->findModel($id),]);var_dump($test);}

I want to store the rendered html output of a form view which uses ActiveForm and Html Helper into a variable within my Controller.

I've tried storing result of a renderPartial directly to a variable, which did not work:

$htmlform = Yii::$app->controller->renderPartial('_form', ['model' => $model]);

I've also tried using output buffering to echo the output into a variable, but I could not store the output:

ob_start();
echo Yii::$app->controller->renderPartial('_form', ['model' => $model]);
$htmlform = ob_get_contents();
ob_end_clean();

View File: _form.php

<?php

use yii\helpers\Html;
use yii\widgets\ActiveForm;

/* @var $this yii\web\View */
/* @var $model frontend\models\Epic */
/* @var $form yii\widgets\ActiveForm */
?>

<div class="epic-form">

    <?php $form = ActiveForm::begin(); ?>

    <?= $form->field($model, 'closed')->textInput() ?>

    <?= $form->field($model, 'title')->textInput(['maxlength' => true]) ?>

    <?= $form->field($model, 'organizationid')->textInput() ?>

<div class="form-group">
<?= Html::submitButton($model->isNewRecord ? Yii::t('app', 'Create') :    Yii::t('app', 'Update'), ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
    </div>

    <?php ActiveForm::end(); ?>

If anyone has an idea on a solution that would be great..

解决方案

I have tried this way in a simple ControllerAction and work right ...in var_dump($test) there the aspected result

public function actionView($id)
{
    $test =  $this->renderPartial('_form', [
        'model' => $this->findModel($id),
    ]);
    var_dump($test);

}
