Yii2 Gridview合并了两列

Question

我在Yii2中有一个gridview,有两列,first_name和last_name.我想将这两个值合并为一个名为full_name的列,如tihs:'first_name'.'.'last_name',可搜索和可过滤.我该怎么做？

Answer 1

试试这种方式:

<?= 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',  ],
    ],


]); ?>

感谢本教程：Yii 2.0：在 GridView Yii 2.0 中按计算/相关字段过滤和排序

本教程仅在first_name&last_name单独搜索时有效，我filter在search model.i.e.

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

步骤 1：向您的基本 Person 模型添加一个 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')
    ];
}

第 2 步：将属性 fullName 添加到您的模型 PersonSearch 并配置您的规则。

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;
}

第 3 步：在视图索引文件中配置 gridview 列

设置视图文件

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