How to Create a Blog with Laravel 5+ Part 7 (CRUD Comment & Helper) Final Part
Advertisement
We’ve done a great job so far, on the previous part, Part 7 (Articles and Comment Form) it focuses on adding a new menu to display lists of blog posts, blog single page, and a comment form and on this article we’ll work on Comment CRUD methods, display approved comments and managing comments in the dashboard area.
Let’s get started.
articles/index.blade.php
With an updated slug, we used slug now instead of the default id, slug is used to display single blog post, e.g. http://127.0.0.1:8000/article/laravel-tutorial-part-7-crud-comment compare to id http://127.0.0.1:8000/article/1.
@extends('main')
@section('title', '| Blog Tutorial')
@section('content')
<div class="blog-header">
<h1 class="blog-title">Articles</h1>
<p class="lead blog-description">The official example template of creating a blog with Bootstrap.</p>
</div>
<div class="row">
<div class="col-sm-8 blog-main">
@if( $posts->count() )
@foreach( $posts as $post )
<div class="blog-post">
<h2 class="blog-post-title">
<a href="/article/{{ $post->post_slug }}">{{ $post->post_title }}</a>
</h2>
<p class="blog-post-meta">{{ date('M j, Y', strtotime( $post->created_at )) }} by <a href="#">{{ Helper::get_userinfo( $post->author_ID )->name }}</a></p>
<div class="blog-content">
{!! nl2br( $post->post_content ) !!}
</div>
</div>
@endforeach
@else
<p>No post added yet!</p>
@endif
{{-- Display pagination only if more than the required pagination --}}
@if( $posts->total() > 6 )
<nav>
<ul class="pager">
@if( $posts->firstItem() > 1 )
<li><a href="{{ $posts->previousPageUrl() }}">Previous</a></li>
@endif
@if( $posts->lastItem() < $posts->total() )
<li><a href="{{ $posts->nextPageUrl() }}">Next</a></li>
@endif
</ul>
</nav>
@endif
</div><!-- /.blog-main -->
<!--Sidebar-->
@include('partials._sidebar')
</div><!-- /.row -->
@endsection
articles/single.blade.php
Added helper to display Category Name instead of just Category ID and we also display lists of comments added, Helper code below.
@extends('main')
@section('title')
| {{ $post->post_title }}
@endsection
@section('content')
<div class="blog-header">
<h1 class="blog-title">{{ $post->post_title }}</h1>
<p>{{ Helper::get_category( $post->category_ID )->category_name }} / {{ date('M j, Y', strtotime( $post->created_at )) }} <a href="{{ route('posts.edit', $post->id) }}">{Edit}</a></p>
</div>
<div class="row">
<div class="col-sm-8 blog-main">
<div class="blog-content">
{!! nl2br( $post->post_content ) !!}
</div><!-- /.blog-post -->
<section class="mt-5" id="respond">
<h2>Comments</h2>
{{--display approved comments--}}
<?php
echo Helper::get_comments( $post->id );
?>
</section>
<section class="mt-5" id="comment">
{{-- display comment form --}}
@includeIf('comments.form', ['post_id' => $post->id])
</section>
</div><!-- /.blog-main -->
<!--Sidebar-->
@include('partials._sidebar')
</div><!-- /.row -->
@endsection
Now that articles views have been updated, lets work on the CRUD methods for comments.
comments/edit.blade.php
@extends('main')
@section('title', '| Edit Comment')

@php
$post = Helper::get_post( $comment->post_id );
@endphp
<div class="row">
<div class="col-md-8">
{{--

{{--

you will need to add a hidden _method field to the form.
