【问题描述】：

我有一个数组

$resultData = [
    array("id"=>1,"name"=>"Cyrus","email"=>"[e-mail]"),
    array("id"=>2,"name"=>"Justin","email"=>"[e-mail]"),
    array("id"=>3,"name"=>"Mason","email"=>"[e-mail]"),
    array("id"=>4,"name"=>"Fulton","email"=>"[e-mail]"),
    array("id"=>5,"name"=>"Neville","email"=>"[e-mail]"),
    array("id"=>6,"name"=>"Jasper","email"=>"[e-mail]"),
    array("id"=>7,"name"=>"Neville","email"=>"[e-mail]"),
    array("id"=>8,"name"=>"Neville","email"=>"[e-mail]"),
    array("id"=>9,"name"=>"Ronan","email"=>"[e-mail]"),
    array("id"=>10,"name"=>"Raphael","email"=>"[e-mail]"),     
    ];

数据提供者：

$dataProvider = new ArrayDataProvider([
        'key'=>'id',
        'allModels' => $resultData,
        'sort' => [
            'attributes' => ['id', 'name', 'email'],
        ],
]);    

还有 Gridview：

echo GridView::widget([
        'dataProvider' => $dataProvider,

        'columns' => [
            ['class' => 'yii\grid\SerialColumn'],
            'id',

            [
            'attribute' => 'name', 
            'value' => 'name',
            ],
            [
            "attribute" => "email",
            'value' => 'email',
            ]

    ]
]);

按原样，代码使我可以在网格中查看数组，并且可以在单击列时对其进行排序。没关系。

但是如何使用过滤呢？

我尝试了以下方法：

$searchModel = ['id' => null, 'name' => '', 'email' => ''];

echo GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,

        'columns' => [
            ['class' => 'yii\grid\SerialColumn'],
            'id',

            [
            'attribute' => 'name', 
            'value' => 'name',
            ],
            [
            "attribute" => "email",
            'filter' => '<input class="form-control" name="filteremail" value="da" type="text">',
            'value' => 'email',
            ]

    ]
]);

但它不起作用。 我是否必须根据 $get 值过滤自己的对象？

【问题讨论】：

“它不工作”是什么意思？搜索输入未显示？

我所说的不工作的意思是，只有当我像在示例中那样放置过滤器时，才会显示输入。 'filter' => '', 'value' => 'email', 但是数据没有被过滤。

【参考方案1】：

我的完整代码解决方案：

$resultData = [
    array("id"=>1,"name"=>"Cyrus","email"=>"[e-mail]"),
    array("id"=>2,"name"=>"Justin","email"=>"[e-mail]"),
    array("id"=>3,"name"=>"Mason","email"=>"[e-mail]"),
    array("id"=>4,"name"=>"Fulton","email"=>"[e-mail]"),
    array("id"=>5,"name"=>"Neville","email"=>"[e-mail]"),
    array("id"=>6,"name"=>"Jasper","email"=>"[e-mail]"),
    array("id"=>7,"name"=>"Neville","email"=>"[e-mail]"),
    array("id"=>8,"name"=>"Neville","email"=>"[e-mail]"),
    array("id"=>9,"name"=>"Ronan","email"=>"[e-mail]"),
    array("id"=>10,"name"=>"Raphael","email"=>"[e-mail]"),     
    ];

function filter($item) 
    $mailfilter = Yii::$app->request->getQueryParam('filteremail', '');
    if (strlen($mailfilter) > 0) 
        if (strpos($item['email'], $mailfilter) != false) 
            return true;
         else 
            return false;
        
     else 
        return true;
    


$filteredresultData = array_filter($resultData, 'filter');


$mailfilter = Yii::$app->request->getQueryParam('filteremail', '');
$namefilter = Yii::$app->request->getQueryParam('filtername', '');

$searchModel = ['id' => null, 'name' => $namefilter, 'email' => $mailfilter];

$dataProvider = new \yii\data\ArrayDataProvider([
        'key'=>'id',
        'allModels' => $filteredresultData,
        'sort' => [
            'attributes' => ['id', 'name', 'email'],
        ],
]);

echo GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,

        'columns' => [
            ['class' => 'yii\grid\SerialColumn'],
            'id',

            [
            'attribute' => 'name', 
            'value' => 'name',
            ],
            [
            "attribute" => "email",
            'filter' => '<input class="form-control" name="filteremail" value="'. $searchModel['email'] .'" type="text">',
            'value' => 'email',
            ]

    ]
]);

【讨论】：

只是为了清楚。如果过滤器不是模型实例，则不会显示过滤器

在过滤函数中使用“不相等”（！==）而不是“不相等”（！=），以避免错误过滤，请参阅stpos

【参考方案2】：

关于上一个灵魂。我创建了一个循环来制作过滤器、列和 searchModel。

$items = [
    array("id" => 1, "name" => "Cyrus", "email" => "[e-mail]"),
    array("id" => 2, "name" => "Justin", "email" => "[e-mail]"),
    array("id" => 3, "name" => "Mason", "email" => "[e-mail]"),
    array("id" => 4, "name" => "Fulton", "email" => "[e-mail]"),
    array("id" => 5, "name" => "Neville", "email" => "[e-mail]"),
    array("id" => 6, "name" => "Jasper", "email" => "[e-mail]"),
    array("id" => 7, "name" => "Neville", "email" => "[e-mail]"),
    array("id" => 8, "name" => "Neville", "email" => "[e-mail]"),
    array("id" => 9, "name" => "Ronan", "email" => "[e-mail]"),
    array("id" => 10, "name" => "Raphael", "email" => "[e-mail]"),
];


$searchAttributes = ['id', 'name', 'email'];
$searchModel = [];
$searchColumns = [];

foreach ($searchAttributes as $searchAttribute) 
    $filterName = 'filter' . $searchAttribute;
    $filterValue = Yii::$app->request->getQueryParam($filterName, '');
    $searchModel[$searchAttribute] = $filterValue;
    $searchColumns[] = [
        'attribute' => $searchAttribute,
        'filter' => '<input class="form-control" name="' . $filterName . '" value="' . $filterValue . '" type="text">',
        'value' => $searchAttribute,
    ];
    $items = array_filter($items, function($item) use (&$filterValue, &$searchAttribute) 
        return strlen($filterValue) > 0 ? stripos('/^' . strtolower($item[$searchAttribute]) . '/', strtolower($filterValue)) : true;
    );


echo GridView::widget([
    'dataProvider' => new ArrayDataProvider([
        'allModels' => $items,
        'sort' => [
            'attributes' => $searchAttributes,
        ],
            ]),
    'filterModel' => $searchModel,
    'columns' => array_merge(
            $searchColumns, [
        ['class' => 'yii\grid\ActionColumn']
            ]
    )
]);

【参考方案3】：

数据提供者：

if ($this->load($params)) 
    $name = strtolower(trim($this->name));
    $resultData= array_filter($resultData, function ($role) use ($name)
        return (empty($name) || strpos((strtolower(is_object($role) ? $role->name : $role['name'])),$name) !== false);
    );


$dataProvider = new ArrayDataProvider([
        'key'=>'id',
        'allModels' => $resultData,
        'sort' => [
            'attributes' => ['id', 'name', 'email'],
        ],
]);

【参考方案4】：

这里是过滤功能的一些改进

function ($item) 
    $mailfilter = strtolower(Yii::$app->request->getQueryParam('filteremail', ''));
    if (strlen($mailfilter) > 0) 
        return strpos(strtolower($item['email']), $mailfilter) !== false;
     else 
        return true;
    

如果您希望过滤器不区分大小写，请在两个地方使用 strtolower()($item['email']) 和 mailfilter) 函数 还要检查 strpos() 函数的类型（“!== false”而不是“!= false”）函数，否则，在尝试过滤字符串的第一个字符时它将不起作用
