我正在为一个SilverStripe页面工作,该页面允许用户根据选定的方面对公文包进行排序

以下是要点/要求:

  • 我有两个方面的类别,他们可以搜索:媒体类型(即广告, 海报、电视、网络)和行业(娱乐、金融、医疗、, 体育等)

  • 应该允许用户同时搜索多个方面,并且 同时跨越媒体类型和行业

  • 在SilverStripe管理员中,因为内容管理器需要能够 为了维护媒体类型和行业的方面名称,我这样做了 有两个管理员模型可以输入名称: MediaTypeTagAdmin和IndustryTagAdmin。下面是数据对象 管理员使用的MediaTypeTag和IndustryTag类 型号:

MediaTypeTag类

<?php
class MediaTypeTag extends DataObject {

    private static $db = array(
        'Name' => 'varchar(250)',
    );

    private static $summary_fields = array(
        'Name' => 'Title',
    );

    private static $field_labels = array(
        'Name'
    );

    private static $belongs_many_many = array(
        'PortfolioItemPages' => 'PortfolioItemPage'
    );

    // tidy up the CMS by not showing these fields
    public function getCMSFields() {
        $fields = parent::getCMSFields();
        $fields->removeByName("PortfolioItemPages");

        return $fields;
    }

    static $default_sort = "Name ASC";
}
我认为最好的方法是使用jQuery和AJAX将所选方面的ID发送到服务器:

(function($) {

    $(document).ready(function() {
        var industry = $('.industry');
        var media = $('.media');
        var tag = $('.tag');
        var selectedTags = "";

        tag.each(function(e) {
            $(this).bind('click', function(e) {
                e.preventDefault();

                $(this).addClass('selectedTag');

                if(selectedTags.indexOf($(this).text()) < 0){
                    if($(this).hasClass('media')){
                        selectedTags += + $(this).attr("id") + "," +"media;";
                    }
                    else{
                        selectedTags += + $(this).attr("id") + "," +"industry;";
                    }
                }
                sendTag(selectedTags);

            }.bind($(this)));
        });

        function sendTag(TagList){
            $.ajax({
                type: "POST",
                url: "/home/getPortfolioItemsByTags/",
                data: { tags: TagList },
                dataType: "json"
            }).done(function(response) {
                var div = $('.portfolioItems');
                div.empty();
                for (var i=0; i<response.length; i++){
                    div.append(response[i].name + "<br />");
                    //return portfolio data here
                }

            })
            .fail(function() {
                alert("There was a problem processing the request.");
           });
        }
    });

}(jQuery));
然而,这就是我陷入困境的地方。虽然我已经找到了一些在CMS之外构建PHP/MySQL分面搜索的不错的例子,但我不确定我可以修改什么以使搜索在CMS内工作。这些示例将facet放在MySQL数据库中的一个表中,而我有两个表(虽然我希望媒体类型和行业facet都有一个MySQL表,但我不确定这是否是一个好主意,因为内容经理希望自己维护facet名称)


是否有任何教程可以提供进一步的帮助,或者可能是我还没有找到的插件?如果有更好的方法来设置此分面搜索,请务必提出建议。这对我来说是相当新鲜的

最有效的方法是在一个查询中根据标记/媒体类型ID进行过滤(您的示例是对每个标记/类型执行一个数据库查询,然后追加结果)

您应该能够执行以下操作:

<?php

public function getPortfolioItemsByTags(){
    $tagString = $this->getRequest()->postVar('tags');

    // remove the last comma from the list of tag ids
    $tagString = substr($tagString, 0, -1);

    //put the tag ids and their tag names (media or industry) into an array
    $tags = explode(";", $tagString);

    //This will hold the associative array of ids to types (i.e. 34 => media)
    $filters = array(
        'media' => array(),
        'industry' => array()
    );
    array_walk($tags, function($val, $key) use(&$filters) {
        list($id, $type) = explode(',', $val);
        $filters[$type][] = $id;
    });

    $portfolioItems = PortfolioItemPage::get()->filterAny(array(
        'MediaTypeTags.ID' => $filters['media'],
        'IndustryTags.ID' => $filters['industry']
    ));

    $return = array();
    foreach($portfolioItems as $portfolioItem){
        $return[] = array(
            'thumbnail' => $portfolioItem->Thumbnail()->Link(),
            'name' => $portfolioItem->H1,
            'logo' => $portfolioItem->Logo()->Link(),
            'excerpt' => $portfolioItem->Excerpt,
            'id' => $portfolioItem->ID
        );
    }

    return json_encode($return);
}

我想这就是我需要的。我试了一下,它看起来就像我需要的那样工作。谢谢!:)
