Question

我试图让我的网站上的搜索功能更简单一些：

Library：调用和过滤结果的单一函数。 Controller：目前有两个函数，一个用于初始PHP加载结果，另一个用于替换搜索页面的结果div。

在这种情况下，我有两个视图几乎完全相同，这使代码有点多余。

与第一个控制器关联的第一个视图加载页面的所有元素+结果div。第二个视图仅更新结果div，仅包含与结果div相关的HTML。

当用户更新搜索过滤器时，AJAX调用会调用第二个控制器并用第二个视图替换初始视图。

如何移动到一个视图？

控制器：

public function display($criteria = null)
{
    // create an instance of the view
    $this->template->content = View::instance('v_results_display');

    // name the page
    $this->template->title = "Search Results";

    //$filtered_results->teacher_results = $this->teachers->filter_teachers(array('criteria' => $_POST['criteria'], 'countries' => $_POST['filters']['countries'], 'stations' => $_POST['filters']['stations'], 'min' => $_POST['min'], 'max' => $_POST['max']));

    if($_POST['criteria'])
    {
        $criteria = $_POST['criteria'];
    }

    # SEARCH BY GROUP
    // allow search by group
    // i.e. if someone searches for math, it should bring up all teachers who teach any kind of math

        switch($criteria)
        {
            case ("math"):
            case ("science"):
            case ("language"):
            case ("college prep"):
            case ("test prep"):
            case ("english"):
            case ("other"):
                $criterions = $this->subjects->get_subjects_return_implode($criteria);
                break;
            default:
                $criterions = $criteria;
                break;
        }

    if($_GET['page'])
    {
        if(is_numeric($_GET['page']))
        {
            $pageNum = intval($_GET['page']);
            if($pageNum == 0)
            {
                $pageNum = null;
            }

        }
        else
        {
            $pageNum = null;
        }

    }

    // call library function for searching
    // maintaining the integrity of the group search
    //$teacher_results = $this->teachers->search_teachers_with_or_without_criteria($criterions, $pageNum);

    //$filtered_results->teacher_results = $this->teachers->filter_teachers(array('criteria' => $_POST['criteria'], 'countries' => $_POST['filters']['countries'], 'stations' => $_POST['filters']['stations'], 'min' => $_POST['min'], 'max' => $_POST['max']));


    $teacher_results = $this->teachers->filter_teachers(array('criteria' => $criterions));

    $teacher_results = $this->teachers->filter_teachers(array('criteria' => $criterions, 'countries' => $_POST['filters']['countries'], 'stations' => $_POST['filters']['stations'], 'min' => $_POST['min'], 'max' => $_POST['max']));

    // a non limited count of all the results, regardless of what page they appear on
    // the previous query has a LIMIT in the SQL, so it can't offer a total count of all teachers
    // across all pages
    $this->template->content->totalResultsCount = count($this->teachers->get_teachers());

    $like_dislike = new Teachers();
    $this->template->content->like_dislike = $like_dislike;

    // pass to view accessible variable
    $this->template->content->teacher_results = $teacher_results;

    // pass criteria variable to be used in view
    // this will probably only be used to echo out to the user what is going on
    $this->template->content->criteria = $criteria;

    // get teacher count for all pages
    $this->template->content->unlimitedTeacherCount = $this->teachers->CountTeachersAllPages($criterions);

    // for the hidden div, which helps with the filtering
    $this->template->content->criterions = $criterions;

    $app_form = new App_Form();
    $this->template->content->app_form = $app_form;

    $app_user_var = new App_User();
    $this->template->content->app_user_var = $app_user_var;

Answer 1

如果没有看到您的代码，很难做出非常详细的评论，但您可以通过查找查询参数来选择请求所需的变量，从而使用单个路由和控制器。您的网址可能如下所示：

GET /path/to/search?q=potatoes

表示初始加载vs

GET /path/to/search?q=potatoes&partial=true

用于AJAX。

这两个请求都会遇到相同的路由和控制器（伪代码跟随！）

route("/path/to/search", mySearchController)

function mySearchController(args) {
    result = do_some_query(args)
    if ('partial' in queryparams) {
        do_partial_render(result)
    } else {
        do_full_render(result)
    }
}

部分/完全呈现情况将涉及模板继承

full.template：

<? include 'header' ?>
<h1>My Nice Search</h1>
<? include 'results_table' ?>
<? include 'footer' ?>

results_table.template

<table>
    <tr>
        <td>{{result}}</td>
    </tr>
</table>

对于一个非常普遍的问题，这是一个非常普遍的答案，伪代码只是示意图。

搜索结果 - 首先是PHP，然后是JS？
