Question

我的寻呼机未更改为所选页面。当我单击到下一页按钮时，它将重新加载页面。我也尝试了没有Pjax容器的情况，但是结果是相同的。我将其他帖子涂成红色，但仍然无法弄清楚。我正在做的是：

$categoriesProvider = new ActiveDataProvider([
            'query' => Page::find()->where(['enable' => 1, 'id_in' => $page_id])->orderBy('sort ASC'),
            'pagination' => [
                'pageSize' => 1,
                'route' => "/".Yii::$app->getRequest()->getQueryParam('page')
            ]
        ]);

        return $this->render('index', [
            'categoriesProvider' => $categoriesProvider
        ]);

并在视图中：

<?php Pjax::begin() ?>

    <div class="content-area col-md-8 col-sm-6 col-xs-12 no-padding">

        <?php if(!empty($categoriesProvider)){
            echo ListView::widget([
                'dataProvider' => $categoriesProvider,
                'layout' => "{summary}\n{items}
                                \n<nav class='post-pagination col-md-12 col-sm-12 col-xs-12'>
                                    {pager}
                                </nav>",
                'itemView' => function($model, $key, $index, $widget){
                    return $this->render('_category', [
                        'model' => $model,
                    ]);
                },
                'pager' => [
                    'nextPageLabel' => ">>",
                    'prevPageLabel' => "<<",
                    'maxButtonCount' => 5,
                    'options' => [
                        'tag' => 'ul',
                        'class' => 'pagination',
                    ]
                ]
            ]);
        }?>
    </div><!-- Content Area /- -->

    <?php Pjax::end(); ?>

网址管理器规则：

'rules' => [
                '<page>/<category>/<product>' => 'splitter/manage-request',
                '<page>/<category>' => 'splitter/manage-request',
                '<page>' => 'splitter/manage-request',
                '' => 'splitter/manage-request'
            ],

似乎Pagination参数与您的URL规则冲突。 Pagination使用page的GET参数将当前页码存储在URL中。但是您的规则还使用page参数，并覆盖Pagination使用的参数。您应该在分页配置中使用其他参数，以避免冲突：

'pagination' => [
    'pageSize' => 1,
    'route' => "/".Yii::$app->getRequest()->getQueryParam('page'),
    'pageParam' => 'paginationPage',
]

请参见https://www.yiiframework.com/doc/api/2.0/yii-data-pagination#$pageParam-detail

或者您也可以在规则中重命名参数以避免在其他地方出现此类问题：

'rules' => [
    '<r_page>/<r_category>/<r_product>' => 'splitter/manage-request',
    '<r_page>/<r_category>' => 'splitter/manage-request',
    '<r_page>' => 'splitter/manage-request',
    '' => 'splitter/manage-request'
],

Yii2分页不会更改页面
