when i run laravel project on my computer after doing php artisan serve as soon as it login it shows error "Attempt to read property "menus" on null"
Please help me
#foreach ($specials->menus as $menu)
<div class="max-w-xs mx-4 mb-2 rounded-lg shadow-lg">
<img class="w-full h-48" src="{{ Storage::url($menu->image) }}" alt="Image" />

</div>
<div class="flex items-center justify-between p-4">
<span class="text-xl text-green-600">${{ $menu->price }}</span>
</div>
</div>
#endforeach
welcomecontroller.php
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Menu extends Model
{
use HasFactory;
protected $fillable = ['name', 'price', 'description', 'image'];
public function categories()
{
return $this->belongsToMany(Category::class, 'category_menu');
}
}
I suppose you forgot to initialize $specials, it is null, that's why you get the error.
Could you try to use dd before foreach statement, so we can see it's content?
{{ dd($specials) }}
UPDATE:
#if(!is_null($specials))
#foreach ($specials->menus as $menu)
<div class="max-w-xs mx-4 mb-2 rounded-lg shadow-lg">
<img class="w-full h-48" src="{{ Storage::url($menu->image) }}" alt="Image" />
<div class="px-6 py-4">
<h4 class="mb-3 text-xl font-semibold tracking-tight text-green-600 uppercase">
{{ $menu->name }}</h4>
<p class="leading-normal text-gray-700">{{ $menu->description }}.</p>
</div>
<div class="flex items-center justify-between p-4">
<span class="text-xl text-green-600">${{ $menu->price }}</span>
</div>
</div>
#endforeach
#else
<div>no item was found</div>
#endif
Your issue is with this line of code (from the comments):
$specials = Category::where('name', 'specials')->first();
->first(); can return null, so when you use it later as $specials->menus, it can be null->menus, which is not valid.
You can use ->firstOrFail() to trigger a 404 in the event $specials results in null, or #foreach($specials->menus ?? [] as $menu) to short-circuit your foreach() with an empty array if $specials is null:
In your Controller:
$specials = Category::where('name', 'specials')->firstOrFail();
return view('welcome', compact('specials'));
OR
In your View:
#foreach($specials->menus ?? [] as $menu)
...
#endforeach
Either case will properly handle your "unsafe" code (unsafe meaning functional, but possible for unhandled errors, like null->menus, etc.) and either trigger a 404 before the view is rendered, or perform a foreach() on an empty array, which does nothing.
I got an error related to the pagination of read notifications. Thank you for your help.
This is my controller code that gives this error when it runs
public function NotificationsRead(User $user)
{
$no = Auth::user()->readNotifications()->paginate(7)->latest()->get();
return view('user-profile.notifications-read', compact('user', 'no'));
}
And when I delete latest(), he gives an error to get()
I do not know how to paginate.
and A have two types notifications
You should do
$no = Auth::user()->readNotifications()->latest()->paginate(7);
In this way you are ordering descending before pagination.
Your code orders the result collection created by pagination.

You need to make some changes in your code, please find below step to change code
Step 1: Please create relations with your foreign key in your model file like
namespace App;
use Illuminate\Database\Eloquent\Model;
class Treeview extends Model
{
protected $table = 'treeview';
public $fillable = ['title','parent_id'];
/**
* Get the index name for the model.
*
* #return string
*/
public function childs() {
return $this->hasMany('App\Treeview','parent_id','id') ;
}
}
Step 2: Add below function in your controller and make some changes according to your table and model object
/**
* Show the application dashboard.
*
* #return \Illuminate\Http\Response
*/
public function manageCategory()
{
$categories = Treeview::where('parent_id', '=', 0)->get();
return view('treeview/categoryTreeview',compact('categories')); // set the path of you templates file.
}
Step 3 : Add below code in your categoryTreeview templates file
<h3>Category List</h3>
<ul id="tree1">
#foreach($categories as $category)
<li>
{{ $category->title }}
#if(count($category->childs))
#include('treeview/manageChild',['childs' => $category->childs]) // Please create another templates file
#endif
</li>
#endforeach
</ul>
Step 4: Please Create another templates file manageChild add below code.
<ul>
#foreach($childs as $child)
<li>
{{ $child->title }}
#if(count($child->childs))
#include('treeview/manageChild',['childs' => $child->childs])
#endif
</li>
#endforeach
</ul>
Output displayed Like:
Category List
Cat_1
Cat_1_par_1
Cat_1_par_2
Cat_1_par_3
Cat_2
Cat_2_par_1
Cat_2_par_2
Cat_2_par_3
Cat_3

I need allow links in messages, when user send message. How I can do this?
#foreach($mess as $message)
<li data-mid="{{ $message->id }}">
<div class="row margin-left-none margin-right-none">
<div class="col-md-2 padding-right-none">
<div class="avatar-user text-center">
<img src="{{ $message->sender->avatar }}" alt="$message->sender->name">
</div>
</div>
<div class="col-md-10 padding-left-none">
<div class="user-name">
<span>{{ $message->sender->name }}
#if(Helper::getOnlineUser($message->sender->id))
<i data-toggle="tooltip" title="Онлайн" class="material-icons online">fiber_manual_record</i>
#else
<i data-toggle="tooltip" title="Оффлайн" class="material-icons offline">fiber_manual_record</i>
#endif
<span class="date float-right">{{ $message->created_at->formatLocalized('%H:%m') }}</span></span>
</div>
<div class="message">
{{ $message->body }}
</div>
</div>
</div>
</li>
#endforeach
This is view of messages.
How I can allow links?
Example: http://example.com in messages =>
http://example.com
I need {!! $message->body !!} ? Or How?
In controller:
$mess = Chat::conversations($conversation)->for($user)->getMessages($limit, $request->page);
I use this package: https://github.com/musonza/chat
There are built in PHP functions to handle this:
<div class="message">
{!! strip_tags($message->body, '<a>') !!}
</div>
Where the second argument is your whitelist.
This has the following advantages:
You're not messing with regex
You're still using blade {!!!!}
You're using well tested code dev'ed by the core team
You can do it by using following php function in your blade,
<?php
function getDataWithURL($text){
// The Regular Expression filter
$reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
// Check if there is a url in the text
if(preg_match($reg_exUrl, $text, $url)) {
// make the urls hyper links
echo preg_replace($reg_exUrl, "".$url[0]." ", $text);
} else {
// if no urls in the text just return the text
echo $text;
}
}
?>
You just need to add this code in your blade file and then you can check and replace the links in your text like this,
<div class="message">
<?php getDataWithURL($message->body);?>
</div>
I hope you will understand.
So I have 2 tables.
DirtyEvent model and Event model.
I am retrieving DirtyEvent with Event which works fine
In blade I have:
#if (\Request::is('profile/event'))
#foreach ($events as $event)
#if (empty( $event->image ))
<div class="card-header">
<span class="card-title"> {{($event->title) }}</span>
</div>
#else
<div class="card-image">
<img class="img-responsive" src="{{ $event->image }}"></img>
<span class="card-title"> {{($event->title) }}</span>
</div>
#endif
<div class="card-content">
<p><strong>Starts: </strong>#php echo ($startdate) #endphp - {{$event->startime }}</p>
<br>
#if ($startdate != $enddate)
<p><strong>Ends: </strong>#php echo ($enddate) #endphp - {{$event->endtime }}</p>
<br>
#endif
<p><strong>Description:</strong></p>
<br>
<p>{{$event->description }}</p>
</div>
<div class="card-action">
<i class="fa fa-pencil-square-o fa-2x" aria-hidden="true"></i>
<form method="POST" action={{ url('events/delete/' . $event->id) }}>
{{ method_field('PATCH') }}
{{ csrf_field() }}
<button type="submit" class="delete" style="border:none;"><i class="fa fa-trash-o fa-2x" aria-hidden="true"></i></button>
</form>
</div>
#foreach ($events->publicevents as $eventss)
{{dd($events)}}
#endforeach
#endforeach
However dd($events) gives me:
DirtyEvent Collection -> relations -> publicevents -> Event collection
But, It is saying that publicevents do not exist in current collection.
Controller
public function index()
{
$id = Auth::id();
$events = DirtyEvent::where('user_id', $id)
->with('publicevents')
->get();
return view('events.viewEvent', compact('events'));
}
Model
public function publicevents()
{
return $this->hasMany('App\Event', 'event_id');
}
I guess not all dirty event objects have events. So check this first with empty() or isEmpty() or count():
#if (!empty($event->publicevents))
#foreach ($event->publicevents as $eventss)
{{ $eventss->id }}
#endforeach
#endif
Update
It should be $event->publicevents, not $events->publicevetns.
