This error occur when the property you want to access that doesn't exist so you should check property isset or not
Here is the example
#if (!is_null($news_comment->user))
<div class="well">
{!! $news_comment->user->name!!}
{{$news_comment->comments}}<br/>
{{$news_comment->created_at}}
</div>
#endif
OR
#if (isset($news_comment->user->id) && isset($news_comment->user->name))
<div class="well">
{!! $news_comment->user->name!!}
{{$news_comment->comments}}<br/>
{{$news_comment->created_at}}
</div>
#endif
Try to use: with () on user
{!! $news_comment->user()->name!!}
Instead of:
{!! $news_comment->user->name!!}

From what I can see it looks like you have included two csrf fields. {{ csrf_field() }} and #csrf This shouldn't be a big issue but I would expect this to throw an error.
Secondly the GalleryStore action in the GalleryController does not return anything. The action should include something like return view('some.view')->with(['data' => $data]);
I want to make a form where you select what exercises you have done and afterwards add them to the database, but the problem is that I can't even submit my post form. The button does nothing when it is pressed.
This is my view file:

This is my route:
Route::get('/addscoreform','HarkkaController#showExcercises');
Route::post('/addscoreform','HarkkaController#storeScores')->name('storeScores');
And this is my controller:
public function storeScores(Request $request)
{
return redirect()->back()->with('success','Form has been sent...');
}
My problem is that I can't even display the success message after submit! It's like the button doesn't work!
It seems like you have tag nesting issues.
<form ...>
<div class="form-group row">
<div class="col-md-12">
<input type="url" name="url" id="url" class="form-control" ...>
</div>
</div>
</div>
...
</form>
What is the third closing? Ensure that the opening and closing tags are nested properly.
A few things which might help organize this better and make it easier to maintain are to eliminate any tags you can, and to break things down into smaller subviews and include statements as much as possible. Subviews are described at https://laravel.com/docs/master/blade#including-subviews.
I have a dropdown menu like this:
{!! Form::open(['method'=>'get']) !!}
<div class="row">
<div class="col-sm-4 form-group">
{!! Form::select('sort',[''=>'Choose Sort','asc'=>'Ascending','desc'=>'Descending'],null,['class'=>'form-control','onChange'=>'form.submit()']) !!}
</div>
<div class="col-sm-5 form-group">
<div class="input-group">
<input class="form-control" id="search"
value="{{ request('search') }}"
placeholder="Search name" name="search"
type="text" id="search"/>
<div class="input-group-btn">
<button type="submit" class="btn btn-warning">Search</button>
</div>
</div>
</div>
</div>
{!! Form::close() !!}
When I choose a item like "Ascending", my page reloaded and the dropdown menu return into "Choose Sort". I want to keep my selected value on dropdown menu.
How can I do that? Thank you very much!
Its simple just need to pass variable
Change Your route as per your requirement
In Your View
{!! Form::open(['method'=>'get','route' => 'document.sort']) !!}
<div class="row">
<div class="col-sm-4 form-group">
{!! Form::select('sort',[''=>'Choose Sort','asc'=>'Ascending','desc'=>'Descending'],isset($sortvalues) ? $sortvalues : '',['class'=>'form-control','onChange'=>'form.submit()']) !!}
</div>
<div class="col-sm-5 form-group">
<div class="input-group">
<input class="form-control" id="search"
value="{{ request('search') }}"
placeholder="Search name" name="search" value="{{ isset($searchvalues) ? $searchvalues : ''}}"
type="text" id="search"/>
<div class="input-group-btn">
<button type="submit" class="btn btn-warning">Search</button>
</div>
</div>
</div>
</div>
{!! Form::close() !!}
And my route
Route::any('/sort', 'DocDocumentController#sorDocument')->name('document.sort');
And finnaly in Controller
public function sorDocument(Request $request)
{
$docDocuments = DocDocument::latest()->paginate(20,['*'],'documentPage');
$searchvalues = $request->search;
$sortvalues = $request->sort;
$viewShare = array_keys(get_defined_vars());
return view('docdocuments.index', compact($viewShare));
}
I don't want to use "id" to edit the product, I want to use the "serial no" column. But I get the following error:
Trying to get property 'serino' of non-object
Product.php
public function edit($serino)
{
$product= DB::select('select * from products where serino=?',[$serino]);
return view("products/edit",compact("product"));
}
index.blade.php
<a href="{{route('products.edit',$product->serino)}}">
<button class="btn btn-info btn-sm"><i class="fas fa-edit"></i> Edit</button>
</a>
edit.blade.php
<form class="form-horizontal" action="{{route('products.update',$product->serino)}}" method="post">
{!! csrf_field() !!}
{!! method_field('put') !!}
<div class="form-group">
<div class="col-sm-12">
<input type="text" class="form-control" value="{{$product->name}}" name="name" placeholder="Product Name">
</div>
</div>
<div class="form-group">
<div class="col-sm-12">
<input type="text" class="form-control" value="{{$product->category}}" name="category" placeholder="Product Category">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-12">
<button type="submit" class="btn btn-success">Save</button>
</div>
</div>
</form>
Good Work..
Your query will return you collection/array of result, no just one Product.
You can use sometihing like this:
$product = DB::table('products')->where('serino', $serino)->first();
Hello I'm new to laravel and I tried to add HTML to a <h6> field like below image .

My question is why it doesn't render in the browser ? What has Laravel done here ?
My Blade code :
#extends('layouts')
<div class="row">
<div class='col-md-6 offset-md-3' >
#section('content')
<h1>{{$card->title}}</h1>
{{$card->created_at}}
<br>
<ul class="list-group">
#foreach($card->notes as $note)
<li class="list-group-item">
<h6>{{$note->body}}</h6> <button class="btn btn-info btn-sm" onclick="togglediv('divform{{$note->id}}')" >Edit</button>
<div class="col-md-6 offset-md-3" id="divform{{$note->id}}" style="display: none;">
<hr>
<form action="/notes/{{$note->id}}/edit" method="POST">
{{ csrf_field() }}
{{ method_field('PATCH') }}
<div class="form-group">
<label for="exampleInputPassword1"><h6>Edit the note</h6></label>
<input type="text-area" name="body" class="form-control" id="body" placeholder="{{$note->body}}">
</div>
<button type="submit" class="btn btn-success btn-sm">Done</button>
</form>
</div>
</li>
#endforeach
<script type="text/javascript">function togglediv(id) {
var div = document.getElementById(id);
div.style.display = div.style.display == "none" ? "block" : "none";
}</script>
</ul>
</div>
</div>

</div>
<button type="submit" class="btn btn-primary">Add Note</button>
</form>

#endsection
Your html is escaped ,if you don't want that use the following syntax to output the html
{!!$note->body!!}
