如何在 laravel 5.8 中创建搜索

Question

我想按帖子“slug”的标题创建搜索，当它搜索帖子时，我想在列表中显示结果。我已经为作者和类别创建了列表页面。当我点击类别时，它会显示当前点击的类别和帖子，对于作者来说是一样的。现在我只想创建一个搜索。当搜索某些东西时，结果显示我的帖子带有一个列表，就像我为作者和类别所做的那样。

注意：我在 header.blade.php 上有搜索字段，并访问了这个标题页到母版页，并在listing.blade.php 上加载了那个母版页

这是 header.blade.php 页面上的搜索代码

<div class="head-search">

  <form role="form" action="/" method="get">
     <!-- Input Group -->
     <div class="input-group">
       <input type="text" name="search" class="form-control" placeholder="Type Something"> 
       <span class="input-group-btn">
         <button type="submit" class="btn btn-primary">Search</button>
       </span>
     </div>
   </form>

</div>

是ListingPageController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Post;

class ListingPageController extends Controller
{
    public function index(){
      return view('front.listing', ['posts'=>[]]);
    }
    public function listing($id){ 
      $posts = Post::with(['comments','category','creator'])->where('status',1)->where('created_by',$id)->orderBy('id','DESC')->paginate(5); 
      return view('front.listing',compact('posts')); 
    }

    public function listing1($id){ 
      $posts = Post::with(['comments','category','creator'])->where('status',1)->where('category_id',$id)->orderBy('id','DESC')->paginate(5); 
      return view('front.listing',compact('posts'));
    }

}

它是listing.blade.php

@extends('front.layout.master') 
@section('content')

<section class="breadcrumb_section">
    <div class="container">
        <div class="row">
        </div>
    </div>
</section>

<div class="container">
<div class="row">
<div class="col-md-8">
    @foreach($posts as $key=>$post)
                @if($key === 0)

<div class="entity_wrapper">
    <div class="entity_title header_purple">
        <h1><a href="{{ url('/category') }}/{{ $post->category_id }}">{{ $post->category->name }}</a></h1>
    </div>
    <!-- entity_title -->

    <div class="entity_thumb">
        <img class="img-responsive" src="{{ asset('post') }}/{{ $post->main_image }} " alt="{{ $post->title }}">
    </div>
    <!-- entity_thumb -->

    <div class="entity_title">

<!-- entity_wrapper -->
      @else
    @if($key === 1)
<div class="row">

            <div class="category_article_title">

            </div>
            <!-- article_social -->

         </div>
        <!-- category_article_body -->

        </div>
    <!-- col-md-6 -->
    @if($loop->last)

    </div>
      @endif
        @endif
         @endforeach


         <div style="margin-left: 40%">
             {{ $posts->links() }}

             </div>

这是我的路线页面

Route::get('/', 'HomePageController@index'); 
Route::get('/category/{id}', 'ListingPageController@listing1');
Route::get('/author/{id}', 'ListingPageController@listing');
Route::get('/listing', 'ListingPageController@index');
Route::get('/details/{slug}', 'DetailsPageController@index')->name('details');

Answer 1

您没有给出 slug 与帖子之间的关系。蛞蝓在不同的桌子上吗？是一对一还是一对多的关系！！！

我不知道，比如说，slug 有一个单独的表，从 slug 到帖子是一对多的关系。那就是一个蛞蝓可能有很多职位。而且，slug 有一个名为 name 的字段，用于 slug 文本。

从您给定的表格中，它表示HomepageController@index。或者您可以根据需要使用单独的控制器和方法。

在方法内部编写查询以获取 slugs 表中 slugs 文本匹配的帖子。喜欢下面，

public function search(Request $request){
  $posts = Post::with(['comments','category','creator'])
               ->join('slugs', 'posts.slug_id', '=', 'slugs.id')
               ->where('slugs.name', 'LIKE', '%'.$request->search. '%')
               ->where('posts.status',1)
               ->where('posts.created_by',$id)->orderBy('posts.id','DESC')->paginate(5); 

   // return to your designated page with data
}

或者，如果posts表有一个slug列，你可以如下替换查询，

$posts = Post::with(['comments','category','creator'])
              ->where('slug', 'LIKE', '%'.$request->search. '%')
              ->where('status',1)->where('created_by',$id)
              ->orderBy('id','DESC')->paginate(5);
