Yii2 Gridview合并两列

我有一个Yii2格式的gridview，有两列，first_name和last_name。 我想将这两个值合并到一个名为full_name的列中，如tihs所示： “名字”。“姓” ，可搜索和过滤。 我该怎么做呢？

试试下面的方法：

<?= GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
        ['class' => 'yii\grid\SerialColumn'],
         [
            'attribute' => 'an_attributeid',
            'label' => 'yourLabel',
            'value' => function($model) { return $model->first_name  . " " . $model->last_name ;},
        ],

        ['class' => 'yii\grid\ActionColumn',  ],
    ],


]); ?>

Gridview列由您列出的属性定义，这些属性实际上转换为yii\grid\DataColumn对象。您可以指定自定义的列，如下所示：

'columns=>[
  'first_column',
  'second_column'=>[ //note that using an index like 'second_column' here, is not necessary, but it helps understand what this column definition attempts to define.
    'attribute' => 'first_name', //must be a known model attribute, used for filtering/sorting
    'value' => ($model, $key, $index, $column) { //here you can specify a custom anonymous function to return more complex data for display, note that it WON'T BE HTML ENCODED.
       return $model->first_name  . " " . $model->last_name ;
     }, 
  ],
  'third_column'
]

您可以通过检查

中的“过滤器和排序”来查找有关定义自定义列的更多信息。在这种情况下，解决方案稍微复杂一些。当涉及到使用属于同一模型的字段管理计算列时，您必须做三件事：

调整表单以在计算字段中处理（通过添加字段并创建适当的getter方法）

调整搜索模型（为计算字段添加andFilterWhere以过滤查询）

调整视图（以处理新的计算字段）

以下对这些活动进行了详细描述。

多亏了本教程：

本教程仅在单独搜索

first_name

和

last_name

时有效，我在

搜索模型中为全名搜索添加了额外的
过滤器
条件<代码>即

'OR CONCAT(first_name, " ", last_name) LIKE "%' . $this->fullName . '%"'

步骤1：向基本人物模型添加getter函数：

设置基础模型

/* Getter for person full name */
public function getFullName() {
    return $this->first_name . ' ' . $this->last_name;
}

/* Your model attribute labels */
public function attributeLabels() {
    return [
        /* Your other attribute labels */
        'fullName' => Yii::t('app', 'Full Name')
    ];
}

步骤2：向model PersonSearch添加属性fullName并配置规则

Setup search model 
/* your calculated attribute */
public $fullName;

/* setup rules */
public function rules() {
   return [
    /* your other rules */
    [['fullName'], 'safe']
   ];
}

/**
 * setup search function for filtering and sorting 
 * based on fullName field
 */
public function search($params) {
    $query = Person::find();
    $dataProvider = new ActiveDataProvider([
        'query' => $query,
    ]);

    /**
     * Setup your sorting attributes
     * Note: This is setup before the $this->load($params) 
     * statement below
     */
    $dataProvider->setSort([
        'attributes' => [
            'id',
            'fullName' => [
                'asc' => ['first_name' => SORT_ASC, 'last_name' => SORT_ASC],
                'desc' => ['first_name' => SORT_DESC, 'last_name' => SORT_DESC],
                'label' => 'Full Name',
                'default' => SORT_ASC
            ],
            'country_id'
        ]
    ]);

    if (!($this->load($params) && $this->validate())) {
        return $dataProvider;
    }

    $this->addCondition($query, 'id');
    $this->addCondition($query, 'first_name', true);
    $this->addCondition($query, 'last_name', true);
    $this->addCondition($query, 'country_id');

    /* Setup your custom filtering criteria */

    // filter by person full name
    $query->andWhere('first_name LIKE "%' . $this->fullName . '%" ' . //This will filter when only first name is searched.
        'OR last_name LIKE "%' . $this->fullName . '%" '. //This will filter when only last name is searched.
        'OR CONCAT(first_name, " ", last_name) LIKE "%' . $this->fullName . '%"' //This will filter when full name is searched.
    );

    return $dataProvider;
}

步骤3：在视图索引文件中配置gridview列

安装视图文件

echo GridView::widget([
    'dataProvider' => $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
        ['class' => 'yii\grid\SerialColumn'],
        'id',
        'fullName',
        ['class' => 'yii\grid\ActionColumn'],
    ]
]);

您好，很抱歉耽搁了，我为您或上一个问题添加了一个新答案，因为评论太短，我希望答案和图托拉尔区域对您来说是清楚的，否则请评论我，以便我可以解释更多。我使用的是yii-basic-app-2.0.11，但不起作用，搜索和排序功能不起作用。我需要将customers表的两个字段合并，并在Logs网格中显示它们
