如何在GridView Yii2中获取合并的数组列表数据

Question

这里我有两张桌子

1. Employeedetails
2. Claimprocess

在employeedetails中，我有8列：

Company_name，Employeecode，Employee_name，father_name，mother_name，wife_name，child1_name和child2_name 。

在Claimprocess表中我有5列：

Company_name，Employeecode，Employee_name，Healthcard_no和claim_for 。

在Claimprocess中，我为employeecode设置了一个依赖下拉列表。例如，如果admin选择自动显示依赖employeecode的company_name，则admin再次选择一个自动显示employee_name和employee关系名称的employeecode，例如father_name，mother_name，wife_name等...

这是employee_code的依赖下拉代码，方法是选择company_name

claimform.php

<?= $form->field($model, 'company_id')->widget(Select2::classname(), [
            'data' => ArrayHelper::map(Company::find()->all(),'id','companyname'),
            'language' => 'en',
            'options' => [
            'placeholder' => 'Select a company ...',
            'onchange' => '
                                $.post( "index.php?r=employeedetails/lists&id='.'"+$(this).val(), function( data ) {
                                  $( "select#claimprocess-employee_id" ).html( data );
                                });',
            ],
            'pluginOptions' => [
                'allowClear' => true
            ],
        ]); 
?>

employeedetailscontroller.php

public function actionLists($id)
{
    $countEmployeedetails = Employeedetails::find()
            ->where(['company_id' => $id])
            ->count();

    $employeedetails = Employeedetails::find()
            ->where(['company_id' => $id])
            ->all();

    if($countEmployeedetails>0){
        foreach($employeedetails as $employee){
            echo "<option value='".$employee->id."'>".$employee->employeecode."</option>";
        }
    }
    else{
        echo "<option>-</option>";
    }

}

这是employee_name和relations_name的相关下拉代码，方法是选择employeecode

claimform.php

<?= $form->field($model, 'employee_id')->widget(Select2::classname(), [
            'data' => ArrayHelper::map(Employeedetails::find()-   >all(),'id','employeecode'),
            'language' => 'en',
            'options' => [
            'placeholder' => 'Select a employeecode ...',
            'onchange' => '
                                $.post( "index.php?r=employeedetails/lists2&id='.'"+$(this).val(), function( data ) {
                                  $( "select#claimprocess-claim_for" ).html( data );
                                }),
                                $.post( "index.php?r=employeedetails/lists1&id='.'"+$(this).val(), function( data ) {
                                  $( "select#claimprocess-employee_name" ).html( data );
                                });',
            ],
            'pluginOptions' => [
                'allowClear' => true
            ],
        ]); 
?>

employeedetailscontroller.php

public function actionLists1($id)
{
    $countEmployeedetails = Employeedetails::find()
            ->where(['id' => $id])
            ->count();


    $employeedetails = Employeedetails::find()
            ->where(['id' => $id])
            ->all();

    if($countEmployeedetails >= 0)
    {
        foreach($employeedetails as $employee)
        {
            echo "<option value='".$employee->id."'>".$employee->name."</option>";
        }
    }
    else{
        echo "<option>-</option>";
    }

}

public function actionLists2($id)
{

    $countEmployeedetails = Employeedetails::find()
            ->where(['id' => $id])
            ->count();


    $employeedetails = Employeedetails::find()
            ->where(['id' => $id])
            ->all();

    if($countEmployeedetails >= 0)
    {
        foreach($employeedetails as $employee)
        {
                echo "<option value='".$employee->id."'>".$employee->father_name."</option>";
                echo "<option value='".$employee->id."'>".$employee->mother_name."</option>";
                echo "<option value='".$employee->id."'>".$employee->wife_name."</option>";
                echo "<option value='".$employee->id."'>".$employee->child1_name."</option>";
                echo "<option value='".$employee->id."'>".$employee->child2_name."</option>";
        }
    }
    else{
        echo "<option>-</option>";
    }
}

在claim_for字段中，我必须选择特定员工的关系名称，所以我所做的是使用array_merge组合所有关系字段，例如father_name，mother_name等，并且我在表单中得到了一个名称。

claimform.php

<?php
          $em = ArrayHelper::map(Employeedetails::find()-  >all(),'id','father_name');
         $emp = ArrayHelper::map(Employeedetails::find()->all(),'id','mother_name');
        $emp1 = ArrayHelper::map(Employeedetails::find()->all(),'id','wife_name');
        $emp2 = ArrayHelper::map(Employeedetails::find()->all(),'id','child1_name');
        $emp3 = ArrayHelper::map(Employeedetails::find()->all(),'id','child2_name');

        $print = array_merge($em,$emp,$emp1,$emp2,$emp3);
        // echo "<pre>";print_r($print);exit();echo "</pre>";

        echo $form->field($model, 'claim_for')->dropDownList($print,['option' => '']); 
?>

问题：

在选择关系时，我在表单中获取所有关系名称，但在gridview中保存时，我得到employee_id而不是merge_array id。

所以我在这里使用这段代码获取关系名称，但我不知道我的编写代码是对还是错：

<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
        ['class' => 'yii\grid\SerialColumn'],

        //'id',
        'company.companyname',
        'employee.employeecode',
        'employee.name',
        'claim_for',
        [
           'attribute' => 'claim_for',
           'format' => 'raw',
           'value' => function($model, $key, $index, $grid) {
                $temp = $model->claim_for;
                $si = Employeedetails::find()->where(['id' => $temp])->one();
                return $si['father_name'];// here how to bring merged array relation name

        },  
        ],
        'healthcard_no',

        ['class' => 'yii\grid\ActionColumn'],
    ],
]); ?>

我一直在寻找两天，但我无法得到它。如果有人可以提供帮助，我会很感激。
