问题描述如何在Yii2中保存字段:解决方案的处理方法

Yii2 save array of form fields to a single database field(Yii2 将表单字段数组保存到单个数据库字段)

本文介绍了Yii2 将表单字段数组保存到单个数据库字段的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着跟版网的小编来一起学习吧！

问题描述

如何在 Yii2 中保存字段数组当前/默认设置仅适用于非数组字段.

以下是我需要保存到单个字段中的表单字段:

<头>
添加
Move
一个输入字段
field($model, 'field1ofarray[{{row-count-placeholder}}]')->textInput(['maxlength' => 255])->label('字段标签') ?>field($model, 'fieldofarray[{{row-count-placeholder}}]')->textInput(['maxlength' => 255])->label('Som 字段') ?>field($model, 'field3ofarray[{{row-count-placeholder}}]')->textInput(['maxlength' => 255])->label('字段标签') ?>field($model, 'field4ofarray[{{row-count-placeholder}}]')->dropDownList(['instock' => 'Instock', 'soldout' =>; '售罄', '预定' => '预定']);?>
Remove

当前控制器(我需要知道如何遍历数组并保存以及在表单中保存其他普通字段):

公共函数actionCreate(){$model = new GrailWall();if ($model->load(Yii::$app->request->post()) && $model->save()) {返回 $this->redirect(['view', 'id' => $model->id]);} 别的 {返回 $this->render('create', ['模型' =>$模型，]);}}

解决方案

就我而言，我根本不需要对控制器进行任何更改.

您可以在数据库记录中创建一个字段，例如config_json"，然后在模型中使用 getter 和 setter 定义一个虚拟属性.

公共函数getConfig(){返回 json_decode($this->config_json);}公共函数 setConfig($value){$this->config_json = json_encode($value);}

还要在规则中将您的虚拟财产设置为安全，以便大规模分配工作.

公共函数规则(){返回 [[['company_id', 'created_at', 'updated_at'], 'integer'],[['类']，'必需']，[['config_json'], 'string'],[['class'], 'string', 'max' =>255],[['配置']，'安全']];}

现在您可以在视图中设置这样的输入

field($model, 'config[ga_id]', ['labelOptions' => ['label' => 'Google Analytics Tracking ID']])->textInput(['maxlength' => true]) ?>

How can I save an array of fields in Yii2 the current/default setup only works for field which aren't array.

Below are the form fields I need to save into the single field:

    

        

            
Add
        
    
    

    

        
Move
        
An Input Field
        

            field($model, 'field1ofarray[{{row-count-placeholder}}]')->textInput(['maxlength' => 255])->label('Field Label') ?>
            field($model, 'fieldofarray[{{row-count-placeholder}}]')->textInput(['maxlength' => 255])->label('Som field') ?>
            field($model, 'field3ofarray[{{row-count-placeholder}}]')->textInput(['maxlength' => 255])->label('Field Label') ?>
            field($model, 'field4ofarray[{{row-count-placeholder}}]')->dropDownList(['instock' => 'Instock', 'soldout' => 'Sold Out', 'scheduled' => 'Scheduled']); ?>
        
        
Remove
    
    

Current Controller (I need to know how I can loop through array and save as well as saving other normal fields in my form):

public function actionCreate()
{
    $model = new GrailWall();
    if ($model->load(Yii::$app->request->post()) && $model->save()) {
        return $this->redirect(['view', 'id' => $model->id]);
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}

解决方案

In my case I didn't need to make any changes to the controller at all.

You can just make a field in your db record, something like 'config_json` and then define a virtual property with getter and setter in your model.

public function getConfig()
{
    return json_decode($this->config_json);
}
public function setConfig($value)
{
    $this->config_json = json_encode($value);
}

Also set your virtual property to be safe in the rules so Massive Assignment works.

public function rules()
{
    return [
        [['company_id', 'created_at', 'updated_at'], 'integer'],
        [['class'], 'required'],
        [['config_json'], 'string'],
        [['class'], 'string', 'max' => 255],
        [['config'], 'safe']
    ];
}

Now you can set inputs like this in your view

field($model, 'config[ga_id]', ['labelOptions' => ['label' => 'Google Analytics Tracking ID']])->textInput(['maxlength' => true]) ?>
