如何在Controller/Action Yii2中获取提交按钮值

Question

我是Yii2 Framework的新手.我想在Controller/Action中获取Submit Button Name/Value.

以下是我的代码:

形成:

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

<?= $form->field($model, 'admin_document_key_id')->dropDownList(ArrayHelper::map(AdminDocumentKey::find()->all(), 'id', 'key_name'), ['prompt' => 'Select']) ?>

<?= $form->field($model, 'key_value')->textInput(['maxlength' => 255]) ?>    

<div class="form-group">
    <?php if (Yii::$app->controller->action->id == "create"): ?>
        <?= Html::submitButton('Create & Add New', ['class' => 'btn btn-primary']) ?>
    <?php endif; ?>

            <?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary', 'value'=>'Create', 'name'=>'submit']) ?>
    <?= Html::a('Cancel', ['/admindocumentvalue'], ['class' => 'btn btn-warning']) ?>
    <?= Html::resetButton('Reset', ['class' => 'btn btn-info']) ?>
</div>

控制器/行动:

public function actionCreate()
 {
    $model = new AdminDocumentValue();

    if ($model->load(Yii::$app->request->post()) && $model->save()) {
        print_r(Yii::$app->request->post());
        exit;
        return $this->redirect(['index', 'id' => $model->id]);
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
 }

它显示以下输出:

Array ( [_csrf] => V0FKc09GclQDbHI1BRVEIR8xOwcjLEFiBSsyGBcZGj4dMWc6JzItbA== [AdminDocumentValue] => Array ( [admin_document_key_id] => 1 [key_value] => Claims ) ) 

但不显示提交按钮名称和值.

我试过了$_POST,$_REQUEST但仍然无法正常工作.

任何帮助,将不胜感激.

谢谢.

Answer 1

通过更改默认的Yii2按钮自己解决了这个问题:

<?= Html::submitButton('Create & Add New', ['class' => 'btn btn-primary', 'value'=>'create_add', 'name'=>'submit']) ?>
<?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary', 'value'=>'Create', 'name'=>'submit']) ?>

然后在控制器中

if (Yii::$app->request->post('submit')==='create_add') {
    // create add
} else {
    // submit
}
