Question

我在app的主页上添加了一个ajax搜索框。它工作正常。但是当我在新结果出现后使用分页时，分页会让我看到旧的结果。我不确定我做得不对。所以寻找专家的帮助来获得解决方案。

我在routes -

中有这些

Route::get('/', 'BookmarkController@index');
Route::post('/', 'BookmarkController@search');

我在他们的控制器中有这些 -

public function index(Request $request)
{
    $tags_list = Tag::orderBy('tag', 'asc')->get();
    $bookmarks = Bookmark::orderBy('created_at','desc')->where('public', '1')->paginate(10);
    $bookmarks_all = Bookmark::orderBy('created_at','desc')->where('public', '1')->get();
    return view('welcome')->with('bookmark', $bookmarks)->with('tags_list', $tags_list)->with('bookmarks_all', $bookmarks_all);
}

public function search(Request $request){
    $search_value = $_POST['search'];

    $bookmarks = Bookmark::orderBy('created_at','desc')->where('public', '1')->where('title', 'rlike', $search_value)->orwhere('description', 'rlike', $search_value)->orwhere('contents', 'rlike', $search_value)->orwhere('tags', 'rlike', $search_value)->paginate(10);
    return view('public_bookmarks')->with('bookmark', $bookmarks);
}

在welcome.blade.php

<div class="container content-container">
<div class="row ">
    <div class="col-sm-12">
        <div class="page-header">
            <div class="row">
                <span class="title col-sm-8">Recent Bookmarks</span>
                <form id="demo-2" class="search-form col-sm-4" method="post">
                    {{ csrf_field() }}
                    <div class="input-group">

                        <input id="search" class="form-control" placeholder="Search" name="search" value="" type="text">

                                $.ajax({
                                    url: '/',
                                    type: "post",
                                    data: {'search':$('input[name=search]').val(), '_token': $('input[name=_token]').val()},
                                    success: function(data){
                                        $('#search-results').html(data);
                                    },

                                    error: function (data) {
                                        console.log('Error on Article extracting');
                                        console.log(data);
                                    }
                                }); 
                            });

您可以使用flash()方法来实现此目的。 Old Input
在search()方法中添加$request->flash()。这将闪烁会话中的当前输入。并且，下次您想通过$request->old('search');检索它这是完整的search()方法：

public function search(Request $request){
    $search_value = $_POST['search']; //assign the current value of search field
    if(!$search_value) //check if current value is not null, means this is new search or previous one
{   
    $search_value = $request->old('search'); //If search_value is null use the old value
    $request->search = $request->old('search'); //add the old value to current request so that it can be flashed
}

    $bookmarks = Bookmark::orderBy('created_at','desc')->where('public', '1')->where('title', 'rlike', $search_value)->orwhere('description', 'rlike', $search_value)->orwhere('contents', 'rlike', $search_value)->orwhere('tags', 'rlike', $search_value)->paginate(10);

    $request->flash(); //adding this request's search value to the session
    return view('public_bookmarks')->with('bookmark', $bookmarks);
}

更新

public function search(Request $request){
    //$search_value = $_POST['search']; change this to use $request
    $search_value = $request->search;

    $bookmarks = Bookmark::orderBy('created_at','desc')->where('public', '1')->where('title', 'rlike', $search_value)->orwhere('description', 'rlike', $search_value)->orwhere('contents', 'rlike', $search_value)->orwhere('tags', 'rlike', $search_value)->paginate(10);

    return view('public_bookmarks')->with('bookmark', $bookmarks)->withInput($request->only('search')); // flashed input to the view
}

现在，在您的视图中，您可以使用old()方法获取值：

{{ $bookmark->appends(['search' => old('search')])->links()}}

更新2：

更改您的ajax调用以使用get方法并将其指向新地址：

type: "get",
url: '/search'

添加一个路径来处理搜索请求作为get方法：

Route::get('/search', 'BookmarkController@search');

在search()方法中，使用$request获取搜索值：

$search_value = $request->search;

当尝试更改页面时，分页用旧的搜索结果替换新的搜索结果
