Question

我正在尝试对ArticlePages的Paginated列表进行排序。文章页面有一个＆＃39;日期＆＃39;字段我想用于排序。分页有效，但排序不起作用。我错过了什么？很多！

根据API / PaginatedList http://api.silverstripe.org/3.1/class-PaginatedList.html 有一个sort（）方法http://api.silverstripe.org/3.1/class-SS_ListDecorator.html#_sort

ArticlePage.php

class ArticlePage extends Page {

    private static $db = array(
        'Place' => 'Text',
        'Date' => 'Date',
    );

ArticleHolder.php

class ArticleHolder_Controller extends Page_Controller {

    public function PaginatedArticles(){
        $paginatedItems = new PaginatedList(ArticlePage::get(), $this->request);    
        $paginatedItems->sort('Date DESC');
        $paginatedItems->setPageLength(4);
        return $paginatedItems;
    }

ArticleHolder.ss

<% loop $PaginatedArticles %>
    <% include ArticlePage %>
<% end_loop %>

Answer 1

$ paginatedItems-＆gt; sort（）方法应该有效。你能检查一下你的记录是否真的有日期值，并且它们是否符合预期？

另一种方法：

PHP

$paginatedItems = new PaginatedList(ArticlePage::get()->sort("Date DESC"), $this->request);
