Show category posts in Laravel is not working - laravel

I want to show posts that are in a category by clicking on them, but when I click on a category,$articles in category.blade.php returns null.
$articles should return articles that have a specific category
this is my index.blade.php:
<div class="tab-pane fade" id="show-categories" role="tabpanel">
<h6 class="sidebar-title">Categories</h6>
<div class="row link-color-default fs-14 lh-24">
#foreach($categories as $category)
<div class="col-6">
<a href="{{ route('cms.category', $category->id) }}">
{{ $category->name }}
</a>
</div>
#endforeach
</div>
</div>
category.blade.php:
#extends('layouts.app')
#section('content')
#forelse ($articles as $article)
<h1>{{$article->title}}</h1>
#empty
<span>array is empty</span>
#endforelse
#endsection
router:
Route::get('cms/categories/{category}', [articlesController::class, 'category'])->name('cms.category');
and articlesController:
public function category(Category $category)
{
return view('cms.category')
->with('category', $category)
->with('articles', $category->articles()->searched()->simplePaginate(3))
->with('categories', Category::all())
->with('tags', Tag::all());
}

Please, don't forget to define the relationship from Category to Article on your model. Like: one category has many articles. For example:
On your Category.php model:
public function articles()
{
return $this->hasMany(Article::class);
}
Then on your, controller, you may call the relationship like this way:
public function category(Category $category)
{
$articles = Category::with("articles")->where("id", $category->id)->simplePaginate(3);
return view('cms.category')
->with('category', $category)
->with('articles', $articles)
->with('categories', Category::all())
->with('tags', Tag::all());
}

Please share the model file and second I prefer to write the category method in a different way.
public function category($category_id)
{
try {
$articles= Article::where('id', $category_id)->get();
return view('cms.category', $articles);
} catch (\Throwable $th) {
Log::error($th->getMessage());
}
}
Let me know if you still face any issue. Try to use dd $articles ..

I appreciate the solution as earlier as possible
sir, I have a question that, I do not want to display my all categories in the sidebar, instead of I want only one category like shoe category and its subcategory I want to display, please guide me how to achieve this. and also i want different category sidebar for different categories,
example,
let's assume we have a shirts listing page where all the shirts, T-shirts and many more shirts related to Shirts Category only.
and i want only Shirts and its subcategory to display in the sidebar.
if i have shoes category and i want to display only shoes category and its subcategory in the sidebar.
please guide me how to achieve this sir,
It is very simple hasMany-belongsTo relationship, let me show you.
<?php
namespace App\models;
use App\pivotes\Catagory;
use Illuminate\Database\Eloquent\Model;
class Catagory extends Model
{
public function children()
{
return $this->hasMany(SELF::class, 'parent_id');
}
public function parentCategory()
{
return $this->hasMany(SELF::class, 'id', 'parent_id');
}
}
Migration file will be
Schema::create('categories', function (Blueprint $table) {
$table->increments('id');
$table->string('category');
$table->unsignedInteger('parent_id')->nullable();
$table->timestamps();
$table->foreign('parent_id')->references('id')->on('comments');
});
for /categories/{category}
Controller method will be
CategoryController extends Controller {
public function show(Category $category)
{
return view('categories.show', $category);
}
}
In view
#foreach( $category->children as $subCategory )
{{ $subcategory->category }}
#endforeach

Get the user name and comment with article id in Laravel

I have 3 tables users, comments, and articles. I have a route like this:
Route::get('/article/{id}', 'ArticlesController#view');
What I want is when I accessing that route I will get User Name and their comment in this article id.
so here's my view function in ArticlesController:
public function view($id){
$article = Article::with('comments')->find($id);
return view('front.single',compact('article'));
}
and here's my single.blade.php code:
<div class="single-grid">
#section('content')
<h1>{{ $article->title }}</h1>
<p>{{ $article->content }}</p>
#show
</div>
<div class="comment-list">
#foreach($article->comments as $comment)
<ul class="comment-list">
<div class="comment-grid">
<img src="/images/avatar.png" alt=""/>
<div class="comment-info">
<h4>{{ $comment->user->name }}</h4>
<p>{{ $comment->comment }}</p>
<h5>{{ $comment->created_at->diffForHumans() }}</h5>
Reply
</div>
<div class="clearfix"></div>
</div>
</ul>
#endforeach
</div>
I'm not sure what how to do it since it gives me error like this:
"Call to undefined relationship [comment] on model [App\User]."
I already define the relation in each model. here's my articles model:
public function comments(){
return $this->hasMany(Comment::class);
}
public function user(){
return $this->belongsTo(User::class);
}
My comment model:
public function article(){
$this->belongsTo(Article::class);
}
public function user(){
$this->belongsTo(User::class);
}
and here's my User model:
public function articles(){
return $this->hasMany(Article::class);
}
public function comments()
{
return $this->hasMany(Comment::class);
}
public function publish(Article $article){
$this->articles()->save($article);
}
here's my table structure:
-users(id,name,email,password,remember_token,created_at,updated_at)
-comments(id,user_id,article_id,comment,created_at,updated_at)
-articles(id,user_id,title,content,created_at,updated_at)
so how can I can User Name just by using this route? thanks.
on Your Comment Model, You need to replace articles to article
public function article(){
$this->belongsTo(Article::class);
}
also, if you want to get user specific comments, than you need to change your controller action code from
$article = Article::with('user.comment')->find($id) to
$article = Article::with('user.comments')->find($id);
I think that your issue comes from the use of compact function : an array is passed to the view instead of an object.
Can you try it like this :
// Controller
public function view($id) {
$article = Article::findOrFail($id);
return view('front.single', $article);
}
<!-- View -->
#foreach($article->comments as $comment)
{{ $comment->user->name }}
{{ $comment->comment }}
{{ $comment->created_at->diffForHumans() }}
#endforeach

How to Call/Display Foreach Loop after Login

I had problem on calling page inside Foreach Loop.Although It is Okay before I click Login, but when I'd try to login,only the html tag where loaded and foreach loop cannot... On my HomeController extends Controller
public function index()
{
return view('pages.welcome');
}
on where I call welcome page. and inside of it which is foreach loop.
<div class="row">
<div class="col-md-8">
#foreach ($posts as $post)
<div class="post">
<h3>{{ $post->title }}</h3>
<p>{{ substr($post->body, 0,300) }}
{{ strlen($post->body) > 300 ? "..." : " " }}</p>
Read More...
</div>
<hr>
#endforeach
</div>
</div>
And I think the problem is my route:
Route::get('/home', 'HomeController#index');
You haven't passed the $posts variable to the view.
Change
public function index()
{
return view('pages.welcome');
}
To something like this:
public function index()
{
$posts = \App\Post::all(); //Assuming your model is called "Post" in the App namespace
return view('pages.welcome', compact('posts'));
}
NOTE: compact('posts') is just a shortcut for ['posts'=>$posts]

get category name in a post record

I have a list containing article posts from all categories. I want to display the category tag in each post on the list and I tried this :
<article class="post bg z-depth-1">
<?php foreach ($article_list as $article): ?>
<div class="post-img">
<a href="post.html">
<img class="retina" src="{{ asset('image/' . $article->image) }}" width="820" height="500" alt="Post Image">
</a>
</div>
<div class="post-content">
<div class="post-header center-align">
<div class="tags">
{{ $article->category->title }}</div>
<h2 class="post-title">{{ $article->title }}</h2>
<div class="date">Posted on {{ Carbon\Carbon::parse($article->created_at)->format('F j, Y') }}</div>
</div>
<div class="post-entry">
<p>sss</p>
</div>
<div class="post-footer">
<div class="post-footer-item">
<span class="text">Read More</span> <i class="fa fa-arrow-circle-right"></i>
</div>
</div>
</div><!-- .post-content -->
<?php endforeach ?>
</article><!-- .post -->
and it gave me error Undefined property: stdClass::$category and I don't know why, I already define the relationship in each model Article and Category. Thanks for the help!
In Article model :
public function category()
{
return $this->belongsTo('App\Category', 'category_id');
}
In Category model :
public function article() {
return $this->hasMany('App\Article', 'category_id');
}
Controller :
public function index() {
$article_list = Article::all();
return view('article/index', compact('article_list', $article_list));
}
What you need to do is eager load those relationships in your controller.
When you pull the records do it like this:
$article_list = Article::with('category')->get();
https://laravel.com/docs/5.3/eloquent-relationships#eager-loading
Change this: $article->category->title
To this: $article->category()->title
When you define the relationship in your model you are also creating a function not a property called category.
public function category()
{
return $this->belongsTo('App\Category');
}
In Category model :
public function article() {
return $this->hasMany('App\Article');
}
Controller :
public function index() {
$article_list = Article::all();
return view('article/index', compact('article_list'));
}
This should work for you now like this.

Is there a more efficient way for grabbing the count of a model within the view? Laravel

I have Images. Each image has comments, and each comment has likes. In my view I'm wanting to display the number of likes a comment has by doing something like this:
#foreach ($images as image)
<img href="$image->url">
<div class="comment-box">
#foreach ($image->comments as $comment)
<div class="comment">
<span class="comment-owner">{{ $comment->owner()->name }}</span> {{ $comment->body }}
<div class="likes">
{{ $comment->likes()->count() }} // ** HERE IS MY N+1 PROBLEM **
</div>
</div>
#endforeach
</div>
#endforeach
However now I'm fetching a query each time there is a comment. There could be hundreds of comments on a page, so id be getting hundreds of queries just to find the count() for likes.
I believe there is a way you can grab the count in a controller by doing something like
DB::raw('count(*) as like_count')
but I do not know how to implement this in my situation. Can I put this kind of thing in my model so that I can always call something like {{ $comment->likes()->like_count }}? How can I make $comment->likes->count() work without having the N+1 problem?
Here is some more code:
Media Model
class Media extends Eloquent {
public function comments()
{
return $this->hasMany('Comment');
}
}
Comment Model
class Comment extends Eloquent {
public function media()
{
return $this->belongsTo('Media');
}
public function likes()
{
return $this->hasMany('Like');
}
}
Like Model
class Like extends Eloquent {
public function comment()
{
return $this->belongsTo('Comment');
}
}
My controller
public function imageViewer($id)
{
$images = Media::with(['comments' => function($query) {
$query->with('likes');
}])->where('resource_id', $id)->simplePaginate(1);
return View::make('image-viewer', compact('images'));
}
Why don't you just use blade's count like this count($comment->likes) assuming that $comment->likes gets the list of likes for a comment
#foreach ($images as image)
<img href="$image->url">
<div class="comment-box">
#foreach ($image->comments as $comment)
<div class="comment">
<span class="comment-owner">{{ $comment->owner()->name }}</span> {{ $comment->body }}
<div class="likes">
{{ count($comment->likes) }}
</div>
</div>
#endforeach
</div>
#endforeach
