Yii2 : 验证是否至少选择了一个复选框 [英] Yii2 : validate if at least one checkbox is selected

问题描述

我有一个用户的多个音乐版本，他想为其创建促销，在促销创建表单上，我们列出了所有版本，我正在使用表单模型来创建促销，其中我为我的几个定义了所有规则在促销表单模型中输入.

我想检查用户在保存表单时是否选择了至少一个版本，但它不起作用，因为复选框是动态创建的.

该字段的表单代码

foreach ($releaseInfo as $releases) {if (!is_null($releases->releaseSongs)) {echo "
".\yii\helpers\Html::activeCheckbox($model, 'selected_releases[]', ['id' => 'release_' . $releases->id, 'onclick' => '$("#songs_'. $releases->id . '").toggle()', 'label' => false]) .&nbsp;".$releases->name ."</图例>";foreach ($releases->releaseSongs as $k => $v) {回声 "<div id='songs_" .$releases->id ."' style='display:none'>";echo "
";echo $v->song->name;echo "</div>";echo "</div>";}}}echo "</fieldset>";

我在模型中的规则

['selected_releases', 'required', 'on' =>['catalog', 'catalog_update'], 'requiredValue' =>1、'当' =>function ($model) {return ($model->scenario == self::SCENARIO_CATALOG_BASED || $model->scenario == self::SCENARIO_CATALOG_BASED_UPDATE);},'whenClient' =>'function(attribute,value){return ("' . $this->scenario . '"=="' . self::SCENARIO_CATALOG_BASED .'" || "' . $this->scenario .'"=="' . self::SCENARIO_CATALOG_BASED_UPDATE .'")}','消息' =>'您必须至少选择一个版本',]

当我提交表单时，发布的输入变量如下所示

 [selected_releases] =>大批([0] =>0[1] =>0)

规则中的 requiredValue 不起作用，因为 selected_releases 是一个值数组，它总是说

您必须至少选择一个版本我如何将 requiredValue 参数选项用于规则，以检查至少一个复选框

或

我是否必须在验证时调用自定义验证方法

解决方案

我为此使用了自定义验证方法，我的验证规则如下

['selected_releases', 'checkreleaseSelection', '开' =>['目录', 'catalog_update'],'当' =>function ($model) {return ($model->scenario == self::SCENARIO_CATALOG_BASED || $model->scenario == self::SCENARIO_CATALOG_BASED_UPDATE);},'whenClient' =>'function(attribute,value){return ("' . $this->scenario . '"=="' . self::SCENARIO_CATALOG_BASED .'" || "' . $this->scenario .'"=="' . self::SCENARIO_CATALOG_BASED_UPDATE .'")}',]

自定义方法

公共函数checkreleaseSelection(){$错误=真；foreach ($this->selected_releases as $selection) {如果($选择){$错误=假；}}如果($错误){$this->addError('selected_releases', '您必须至少选择一个版本才能继续');}};

I have multiple Music releases for a user for which he wants to create a promo, on the promo create form we have all the releases listed and I am using a form model for creating the promo where I define all rules for my several inputs in the promo form model.

I want to check if at-least one release is selected by the user when saving the form but it is not working as the checkboxes are created dynamically.

my form code for that field

foreach ($releaseInfo as $releases) {
    if (!is_null($releases->releaseSongs)) {
        echo "<fieldset><legend>" . \yii\helpers\Html::activeCheckbox($model, 'selected_releases[]', ['id' => 'release_' . $releases->id, 'onclick' => '$("#songs_' . $releases->id . '").toggle()', 'label' => false]) . "&nbsp;" . $releases->name . "</legend>";
        foreach ($releases->releaseSongs as $k => $v) {
            echo "<div id='songs_" . $releases->id . "' style='display:none'>";
            echo "<div>";
            echo $v->song->name;
            echo "</div>";
            echo "</div>";
        }
    }
}

echo "</fieldset>";

my rule in model

['selected_releases', 'required', 'on' => ['catalog', 'catalog_update'], 'requiredValue' => 1,
    'when' => function ($model) {return ($model->scenario == self::SCENARIO_CATALOG_BASED || $model->scenario == self::SCENARIO_CATALOG_BASED_UPDATE);},
    'whenClient' => 'function(attribute,value){return ("' . $this->scenario . '"=="' . self::SCENARIO_CATALOG_BASED . '" || "' . $this->scenario . '"=="' . self::SCENARIO_CATALOG_BASED_UPDATE . '")}',
    'message' => 'You must select atleast one release',
]

when i submit my form the posted input variable looks like this

 [selected_releases] => Array(
            [0] => 0
            [1] => 0
 )

the requiredValue in the rule does not work because the selected_releases is an array of values it always says that

You must select atleast one release how shoule i use the requiredValue parameter option for rules in a way that it checks for atleast one slection of the checkbox

OR

do i have to make a custom validation method an call it when validating

解决方案

i used custom validation method for this purpose , my validation rule looks like following

['selected_releases', 'checkreleaseSelection'
    , 'on' => ['catalog', 'catalog_update'],
    'when' => function ($model) {return ($model->scenario == self::SCENARIO_CATALOG_BASED || $model->scenario == self::SCENARIO_CATALOG_BASED_UPDATE);},
    'whenClient' => 'function(attribute,value){return ("' . $this->scenario . '"=="' . self::SCENARIO_CATALOG_BASED . '" || "' . $this->scenario . '"=="' . self::SCENARIO_CATALOG_BASED_UPDATE . '")}',
]

Custom method

public function checkreleaseSelection()
{
    $error = true;
    foreach ($this->selected_releases as $selection) {
        if ($selection) {
            $error = false;
        }
    }
    if ($error) {
        $this->addError('selected_releases', 'You must select atleast one of your releases to continue');
    }
};
