I want to update selected items and this is my code:
controller:
public function updatesyncFiles(Request $request , $id){
$product_item = Singleproduct::find($id);
$files = $request->input('files');
if ($product_item && is_array($files)){
$product_item->file()->sync($files);
}
}
blade:
#if( $files && count($files) > 0)
<form action="{{ route('product.sync_files' , $product_item ) }}" method="post">
{{ csrf_field() }}
<h3 style="color: black; ">فایل مربوطه:</h3>
<section class="panel">
<table class="table table-striped table-advance table-hover">
<ul>
#foreach($files as $file)
<li>
<input type="checkbox" name="files[]" value="{{ $file->file_id }}" {{ isset($id) && in_array($file->id,$id) ? 'checked':'' }}>
{{ $file->file_name }}
</li>
#endforeach
</ul>
<div class="form-group">
<input type="submit" class="btn btn-danger" name="submit_product_files" value="ذخیره اطلاعات">
</div>
</table>
</section>
</form>
#endif
and the error is: "Undefined variable: product_item"
what is the problem??
You should pass your variables to the view like this:
return view('your_view', [
'product_item' => $product_item
]);
Also not that you should pass an array to 2nd argument of the route method:
{{ route('product.sync_files', ['product_id' => $product_item]) }}

i'm trying to build a polls system using livewire but i got some errors
here is my blade
#foreach ($questions as $index => $question)
<div class="row">
<div class="box-header with-border">
<i class="fa fa-question-circle text-black fs-20 me-10"></i>
<h4 class="box-title">{{ $question->title }}</h4>

class="radio-col-primary" value="{{ $key }}">
<label
for="answer{{ $question->id }}{{ $key }}">{{ $answer }}</label>
#endforeach
#error('question')
<div class="text-danger text-bold">{{$message}}</div>
#enderror
</div>
</div>
</div>
#endforeach
my Livewire class
public $question = [];
public function render() {
$category = PollCategory::findOrFail($this->category->id);
$subCategories = PollSubCategory::where('poll_category_id', $category->id)->get();
$answers = PollAnswer::all();
return view('livewire.polls', compact('category', 'subCategories', 'answers'));
}
The Error is
Property [$question41] not found on component: [polls]
Any help please ?
you did it wrong way,
solution:
<input wire:model="question.{{ $question->id }}"
$question{{ $question->id }} equal $question41
$question.{{ $question->id }} equal to $question[41]
that's why u receive error Property [$question41] not found on component

Note: I just started learning laravel. Thanks
Try to delete the method POST. Update will use PUT as Method.
<form action="{{ route('BatterFirst.update',$batterFirst->id) }}" method="POST">
#csrf
#method('PUT')
and then change inside your route function this. Pass the id inside a array.
"{{route('BatterFirst.update',['id' => $batterFirst->id])}}"
then will ĺooking so:
<form action="{{ route('BatterFirst.update',['id' => $batterFirst->id]) }}" method="PUT">
#csrf
#method('PUT')
It happens CZ of wrong naming of table and model, folders

My route web.php
Route::resource('/kategori', 'CategoryController',
['except' => ['create', 'show']]);
It should be like this
public function index()
{
$categories = Category::orderBy('created_at', 'DESC')->paginate(10);
$title = ''; //your title
return view('categories.index', compact('categories','title'));
}
because title not getting value from controller.
You dont pass variable title to view
Add some like this:
$title = 'Your title';
return view('categories.index', compact('categories','title'));
If title is a field of Category
If title is a field/member of Category model, then you would do {{ $category->title }}. I think this is the real error.
Otherwise
You need to define and send the variable as other have said.
$tile='Your Title';
return view('categories.index', compact('categories','title'));
I want to create a view in laravel that has a function to import an excel file into the database and show it in a table inside a view.

As conveyed by #gbalduzzi you need to return the data to the view as
return back()->with(['arr' => $arr]);
and access in your view as
#if(session()->has('arr'))
<table class="table table-striped table-hover table-reflow">
#php $arr = session('arr'); #endphp
#foreach($arr as $key => $value)
<tr>
<th ><strong> {{ $value['name'] }}: </strong></th>
<td>{{ $value['details'] }} <td>
</tr>
#endforeach
</table>
#endif
Docs
Change
return back()->with($arr);
with
return back()->with(['arr' => $arr]);
return back()->with('arr', $arr); // Should be equivalent
return back()->compact($arr); // Should be equivalent
The with method doesn't accept only a single value: you need to specify an array, a key and a value or use the compact method
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.
