在Yii2框架中创建表单时生成随机ID

use yii\widgets\ActiveForm;

<?= $form->field($model, 'random_id')->hiddenInput(['value' => uniqid()])->label(false) ?>

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

    if ($model->load(Yii::$app->request->post()) && $model->save()) {
        // 表单数据加载成功，进行相应的处理
        return $this->redirect(['view', 'id' => $model->id]);
    } else {
        // 显示表单
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}
