This is my searchcontroller
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Post;
use Illuminate\Support\Facades\Input;
use Carbon\Carbon;
class SearchController extends Controller
{
public function index() {
$countTodayOrders = Post::whereRaw('Date(created_at) = CURDATE()')->count();
$yesterday_posts = Post::whereRaw('Date(created_at) = DATE_ADD(CURDATE(), INTERVAL -1 DAY)')->count();
$weekly_posts = Post::whereBetween( 'updated_at', [Carbon::today()->startOfWeek(), Carbon::today()->endOfWeek()] )->count();
$monthy_posts = Post::whereRaw('MONTH(created_at) = ?', Carbon::today()->month)->count();
$q = Input::get('q');
$posts = Post::where('title','LIKE','%'.$q.'%')->orWhere('body','LIKE','%'.$q.'%')->paginate('2');
$resultcount = Post::where('title','LIKE','%'.$q.'%')->orWhere('slug','LIKE','%'.$q.'%')->count();
return view('theme.search', compact('posts', 'resultcount', 'countTodayOrders', 'yesterday_posts', 'weekly_posts', 'monthy_posts', 'q'));
}
}
This is my search.Blade
#extends('layout.app')
#section('title')
Search results
#endsection
#section('content')
<div class="col-md-9 technology-left">
<div class="tc-ch wow fadeInDown" data-wow-duration=".8s" data-wow-delay=".2s">
<h2> Here is <b> {{ $resultcount }} </b> result for your query.</h2>
<hr/>
<!-- panel group -->
<div class="row form-group">
#foreach($posts as $post)
<div class="col-xs-12 col-md-6">
<div class="panel panel-default">
<div class="panel-image hide-panel-body">
<img src="{{ url('/storage') }}/{{ $post->image }}" class="img-responsive panel-image-preview" alt="{{ $post->title }}" />
</div>
<div class="panel-body">
<h4>{{ $post->title }}</h4>
<p>{{ substr(strip_tags($post->body), 0, 50) }}{{ strlen(strip_tags($post->body)) > 50 ? "..." : "" }}</p>
</div>
<div class="panel-footer text-center">
<span class="glyphicon glyphicon-share-alt"></span>
</div>
</div>
</div>
#endforeach
</div>
<!-- panel group -->
<div class="row text-center">
<div class="col-md-12">
{!! $posts->links() !!}
</div>
</div>
</div>
</div>
#endsection
My route
Route::any('/search', ['uses' => 'SearchController#index', 'as' => 'search.index']);
My search box
<!-- search box -->
<form action="/search" method="post" role="search">
{{ csrf_field() }}
<div class="input-group">
<input type="text" class="form-control" name="q" placeholder="Search..."> <span class="input-group-btn">
<button type="submit" class="btn btn-default">
<span class="glyphicon glyphicon-search"></span>
</button>
</span>
</div>
</form>
<!-- search box -->
Why is that?

Answer 1

The problem is most probably with your q parameter not getting passed in the page links.
Just add it In your controller like this:
$q = Input::get('q');
$posts = null;
if($q) {
$posts = Post::where('title','LIKE','%'.$q.'%')
->orWhere('body','LIKE','%'.$q.'%')
->paginate(2)
->appends('q', $q);
}
In your blade you should add an if statement to check if there are any posts
#if($posts and $posts->count())
// show posts
#else
// show a nothing found message
#endif
