Arrays 使用带有数据数组的Yii2和带有排序和筛选的Gridview

我有一个数组

$resultData = [
    array("id"=>1,"name"=>"Cyrus","email"=>"risus@consequatdolorvitae.org"),
    array("id"=>2,"name"=>"Justin","email"=>"ac.facilisis.facilisis@at.ca"),
    array("id"=>3,"name"=>"Mason","email"=>"in.cursus.et@arcuacorci.ca"),
    array("id"=>4,"name"=>"Fulton","email"=>"a@faucibusorciluctus.edu"),
    array("id"=>5,"name"=>"Neville","email"=>"eleifend@consequatlectus.com"),
    array("id"=>6,"name"=>"Jasper","email"=>"lectus.justo@miAliquam.com"),
    array("id"=>7,"name"=>"Neville","email"=>"Morbi.non.sapien@dapibusquam.org"),
    array("id"=>8,"name"=>"Neville","email"=>"condimentum.eget@egestas.edu"),
    array("id"=>9,"name"=>"Ronan","email"=>"orci.adipiscing@interdumligulaeu.com"),
    array("id"=>10,"name"=>"Raphael","email"=>"nec.tempus@commodohendrerit.co.uk"),     
    ];

数据提供者：

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

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'],
        ],
]); 

以及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',
            ]

    ]
]);

$searchModel=['id'=>null，'name'=>''，'email'=>''；
echo GridView:：小部件([
“dataProvider”=>$dataProvider，
“filterModel”=>$searchModel，
“列”=>[
['class'=>'yii\grid\SerialColumn']，
“id”，
[
'属性'=>'名称'，
“值”=>“名称”，
],
[
“属性”=>“电子邮件”，
'过滤器'=>''，
'值'=>'电子邮件'，
]
]
]);

但它不起作用。

我是否必须根据$get值对对象进行自我筛选？

    array("id"=>10,"name"=>"Raphael","email"=>"nec.tempus@commodohendrerit.co.uk"),     
    ];

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

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

关于上一个解决方案。我创建了一个循环来创建过滤器、列和搜索模型

$items = [
    array("id" => 1, "name" => "Cyrus", "email" => "risus@consequatdolorvitae.org"),
    array("id" => 2, "name" => "Justin", "email" => "ac.facilisis.facilisis@at.ca"),
    array("id" => 3, "name" => "Mason", "email" => "in.cursus.et@arcuacorci.ca"),
    array("id" => 4, "name" => "Fulton", "email" => "a@faucibusorciluctus.edu"),
    array("id" => 5, "name" => "Neville", "email" => "eleifend@consequatlectus.com"),
    array("id" => 6, "name" => "Jasper", "email" => "lectus.justo@miAliquam.com"),
    array("id" => 7, "name" => "Neville", "email" => "Morbi.non.sapien@dapibusquam.org"),
    array("id" => 8, "name" => "Neville", "email" => "condimentum.eget@egestas.edu"),
    array("id" => 9, "name" => "Ronan", "email" => "orci.adipiscing@interdumligulaeu.com"),
    array("id" => 10, "name" => "Raphael", "email" => "nec.tempus@commodohendrerit.co.uk"),
];


$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']
            ]
    )
]);

$items=[
数组（“id”=>1，“name”=>“Cyrus”，“email”=>”risus@consequatdolorvitae.org"),
数组（“id”=>2，“name”=>“Justin”，“email”=>“ac.facilisis”。facilisis@at.ca"),
数组（“id”=>3，“name”=>“Mason”，“email”=>“in.cursus。et@arcuacorci.ca"),
数组（“id”=>4，“name”=>“Fulton”，“email”=>”a@faucibusorciluctus.edu"),
数组（“id”=>5，“name”=>“Neville”，“email”=>”eleifend@consequatlectus.com"),
数组（“id”=>6，“name”=>“Jasper”，“email”=>“lectus”。justo@miAliquam.com"),
数组（“id”=>7，“name”=>“Neville”，“email”=>“Morbi.non。sapien@dapibusquam.org"),
数组（“id”=>8，“name”=>“Neville”，“email”=>“调味品”。eget@egestas.edu"),
数组（“id”=>9，“name”=>“Ronan”，“email”=>“orci”。adipiscing@interdumligulaeu.com"),
数组（“id”=>10，“name”=>“Raphael”，“email”=>“nec。tempus@commodohendrerit.co.uk"),
];
$searchAttributes=['id'，'name'，'email']；
$searchModel=[]；
$searchColumns=[]；
foreach（$searchAttributes作为$searchAttribute）{
$filterName='filter'.$searchAttribute；
$filterValue=Yii:：$app->request->getQueryParam（$filterName，”）；
$searchModel[$searchAttribute]=$filterValue；
$searchColumns[]=[
'attribute'=>$searchAttribute，
'过滤器'=>''，
“值”=>$searchAttribute，
];
$items=数组\过滤器（$items，函数（$item）使用（&$filterValue，&$searchAttribute）{
返回strlen（$filterValue）>0？stripos（'/^'.strtolower（$item[$searchAttribute]）。/'，strtolower（$filterValue））：true；
});
}
echo GridView:：小部件([
“dataProvider”=>新的ArrayDataProvider([
“所有型号”=>$items，
“排序”=>[
“属性”=>$searchAttributes，
],
]),
“filterModel”=>$searchModel，
“列”=>数组\u合并(
$searchColumns[
['class'=>'yii\grid\ActionColumn']
]
)
]);

数据提供者：

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

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'],
        ],
]);

以下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;
    }
}

如果希望过滤器不区分大小写，请在两个位置使用strtolower（）函数（$item['email']）和mailfilter

还请检查strpos（）函数的类型（“！==false”而不是“！=false”），否则，在尝试筛选字符串的第一个字符时，它将不起作用

---

你说的“它不起作用”是什么意思？搜索输入没有显示？我不工作的意思是，只有当我在样本中放入类似的过滤器时，才会显示输入。”过滤'=>''，'值'=>'电子邮件'，但数据未被过滤。只是为了澄清。如果筛选器不是模型的实例，则不会显示筛选器在筛选器函数中使用“不相同”（！=）而不是“不相等”（！=），以避免错误的筛选，请参阅
