yii2

Question

我正在尝试一次在 table 多行上保存工作日的时间表... 我做错了，仍然给我错误。我已经看到其他人的表格输入，但无法正确处理。我真的需要一些其他的眼睛。

我遇到了与 https://phppedia.com/en/knowledge-base/32481399/yii2-insert-multiple-records-of-a-same-table

类似的问题

型号：

public
    function rules()
    {
        return [
            ['store_id', 'string'],
            ['day', 'string'],
            ['start_hour', 'string'],
            ['end_hour', 'string'],
            ['holiday','boolean'],
        ];
    }

控制器：

public function actionCreate()
    {
        $count = count(Yii::$app->request->post('Openhour', []));
        $model = [new Openhours()];
        for ($i = 1; $i < $count; $i++) {
            $model[] = new Openhours();
        }

        if ($model->loadMultiple($model, Yii::$app->request->post())) {
            foreach ($model as $model) {
               $model->save(false);
            }
        }

        return $this->render('create', ['model' => $model,]);
    }

首先你有一个对象数组，你必须使用复数名称。

所以model变成了models。

其次，您必须使用函数从请求 Model::loadMultiple($models) 加载多个模型并验证多个模型 Model::validateMultiple($models)。

现在在您的控制器中：

public function actionCreate()
{
    $count = count(Yii::$app->request->post('Openhour', []));
    $models = [new Openhours()];
    for ($i = 1; $i < $count; $i++) {
        $models[] = new Openhours();
    }

    if (Model::loadMultiple($models, Yii::$app->request->post()) && Model::validateMultiple($models)) {
        foreach ($models as $model) {
            $model->save(false);
        }
    }

    return $this->render('create', ['models' => $models]);
}

现在在您的 _form.php 中更改行：

<?php foreach ($model as $index => $model): ?>

收件人：

<?php foreach ($models as $index => $model): ?>
