I am trying to make a blog foreach that see this erro
Invalid argument supplied for foreach() (View:
my site https://weadam.com/
my code is:
controller:
public function index()
{
$localetmp = Session::get('locale');
$blogs = #json_decode(file_get_contents("https://www.weadam.com/blogs/wp-json/wp/v2/posts?per_page=4&lang=" . $localetmp));
$blogsold = Blog::orderBy('id','desc')->take(100)->get();
foreach ((array)$blogs as $blog){
// $blog->elapsed = $this->time_elapsed_string('#'.$blog->date);
// $blog->date = date("d F Y",$blog->date);
}
$error = "";
return view('home-new',['blogs' => $blogs]);
}
and view is:
<div class="eng-home-blog">
<div class="col-sm-9 home-post-disp bx-shadow brd-radius bg-white">
#foreach($blogs as $blog)
#if($blog->sticky)
<img src="{{$blog->fimg_url}}" alt="" class="img-responsive brd-radius bx-shadow">
<div class="hm-post-date">{{$blog->date}}</div>
<h3>{{$blog->title->rendered}}</h3>
<p>{!!$blog->excerpt->rendered!!}</p>
<span>{{__("READ MORE")}}</span>
#endif
#endforeach
</div>
</div>
pass true as secondary param at json_decode function
$blogs = #json_decode(file_get_contents("https://www.weadam.com/blogs/wp-json/wp/v2/posts?per_page=4&lang=" . $localetmp),true);
now you have to fetch this blog data as associative data. not as an object. here's the example code for it
<div class="eng-home-blog">
<div class="col-sm-9 home-post-disp bx-shadow brd-radius bg-white">
#foreach($blogs as $blog)
#if($blog['sticky'])
<img src="{{$blog['fimg_url']}}" alt="" class="img-responsive brd-radius bx-shadow">
<div class="hm-post-date">{{$blog['date']}}</div>
#endif
#endforeach
</div>
</div>
You can simply use forelse it will take care of the empty case
#forelse($blogs as $blog)
// do what ever you want to do
#empty
<div> Nothing to show </div>
#endforelse
Hope it helps reference.
Thanks.

My problem is: When i click to send button with form. All information has been upladed to database exept image. That's why i could not catch to image from database to show users.
Here is the Migration Codes:
public function up()
{
Schema::create('haberler', function (Blueprint $table) {
$table->id();
$table->string('baslik')->default('');
$table->string('kategori')->nullable();
$table->string('icerik')->nullable();
$table->string('resim')->nullable();
$table->timestamp('created_at')->useCurrent();
$table->timestamp('updated_at')->useCurrent();
});
}
Here is the function codes
public function yenihaberekle(Request $request){
$request->validate([
'kategori'=>'required',
'baslik'=>'required|min:6|max:50',
'icerik'=>'required|min:50',
'resim' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
]);
$file_name = time() . '.' .request()->resim->getClientOriginalExtension();
request()->resim->move(public_path('images', $file_name));
$baslik = $request->baslik;
$kategori = $request->kategori;
$icerik = $request->icerik;
$stu = new haberler();
$stu->baslik = $baslik;
$stu->kategori = $kategori;
$stu->icerik = $icerik;
$stu->save();
return redirect()->back()->with('success','Haber veya Kampanya Başarıyla Eklenmitir. / News or Campaing has added by succesfuly');
}
and i try to catch code on front page

Allright guys. I fixed to problem.
First, I forgot in the function:

Second, in my view blade my code was:
<img src="{{ asset('images/'. $haberler->resimler) }}"
But my function was resim so now it works.

Check out the documentation on Dom Diffing Issues. It looks like you need to add a wire:key="{{ $conversations->id }}" attribute into your a tag so that Livewire can track changes to the list of conversations.
There is link to my previous problem where is code,maybe it helps you
Parse error: syntax error, unexpected '__construct' (T_STRING), expecting function (T_FUNCTION) or const (T_CONST)
this is problem i get
Undefined index: item (View: C:\xampp\htdocs\laravel\resources\views\shoppingCart.blade.php)
this error is there <strong><?php echo e($product['item']['name']); ?></strong>
this is my route
Route::get('shoppingCart', 'WebController#shoppingCart')->name('get.shoppingCart');
this is in my webcontroller
public function shoppingCart(){
if(!Session::has('cart')){
return view('shoppingCart');
}
$oldCart = Session::get('cart');
$cart = new Cart($oldCart);
return view('shoppingCart',['products'=>$cart->items]);
}
this is link for cart
<li>CART <span class="badge">{{Session::has('cart') ? '!' : ''}}</span></li>
And this is my code for shoppingCart
#extends('layouts.main')
#section('content')
#if(Session::has('cart'))
<div>
<div>
<ul class="list-group">
#foreach($products as $product)

#endforeach
</ul>
</div>
</div>
#else
<div>

Firstly you can check if you have data or not on $cart->items while writing dd($cart->items); on the your function . Follow my comments .
public function shoppingCart(){
if(!Session::has('cart')){
return view('shoppingCart');
}
$oldCart = Session::get('cart');
$cart = new Cart($oldCart);
//dd($cart->items) /*uncomment this and check if you have data or not if you have no then problem is */
return view('shoppingCart',['products'=>$cart->items]); /* on the other if you have data dont forget those line and look at my comment on blade.php */
}
Your blade.php
#extends('layouts.main')
#section('content')
#if(Session::has('cart'))
<div>
<div>
<ul class="list-group">
#foreach($products as $product)
<li class="list-group-item"></li>
<strong>{{$product['item']['name']}}</strong>
<!--Look at here you remembe you were add products writing `['products'=>$cart->items]` then you be care calling your datas first you be relay on your codes you are working array (it seems you are working with objects then you need to call it $products->item->name Secondly you remember on the function you were add your data `['products'=>$cart->items]` like this if there is no child items object on $cart->items then you need to call it like
foreach($products as $product))
{
echo $product->name; //if it is array then echo $product['name'];
}
-->
<li>Odstrániť</li>
#endforeach
</ul>
</div>
</div>
#else
<div>
<h2>V košíku nemáš žiadne položky!!!</h2>

I'm kind of new to laravel and trying to pull data from a database but keep hitting an error page saying there's an undefined variable within the view.
I'm supposing there's something I'm doing wrong (or not doing) within the controller. So I have a create.blade.php that posts data from a form to the database and everything works fine, however I want it such that after posting to the database to redirect to the show.blade.php showing the uploaded data and here is where I hit a brick wall with the error messages.
This is my store function within the controller -
public function store(Request $request)
{
$data4page = new Data4page;
$data4page->h1Ttle = $request->h1Ttle;
$data4page->h4Ttle = $request->h4Ttle;
$data4page->description = $request->description;
$data4page->save();
/*redirecting to the content's show page*/
return redirect()->route('content.show', $data4page->id);
}
And this is the show function within the same controller -
public function show($id)
{
//
$data4page = Data4page::find($id);
return view('digital.show')->with(compact('data4page'));
}
The error message I'm getting is -
Undefined variable: data4page (View: /var/www/html/theproject/resources/views/content/show.blade.php)
And in the show.blade.php this is a sample of what I have -
<h1>{{ $data4page->h4Ttle }}</h1>
<p>{{ $data4page->description }}</p>
<h4>{{ $data4page->h4Ttle }}</h4>
Having said all that, I have also tried various means of returning the view within the show function of the controller but all these result in the same error message above. These variants include -
return view('content.show')->with('data4page', $data4page);
return view('content.show',['data4page'=>$data4page]);
Update: I earlier had typos but now the error I get is -
undefined variable: {"id":9,"h1Ttle":"h1 sample text","h4Ttle":"h4 sample text","description":"body text goes here"} (View: /var/www/html/theproject/resources/views/content/show.blade.php)
This is the show.blade.php -
#extends('main')
#section('title')
#section('content')
<div class="app-template">
<main class="wrapperMain">
<div class="">
<aside class="navSidebar">
<nav class="navProperty">
<h1 class="navProperty-title">{{ $data4page->h1Ttle }}</h1>
</nav>
<footer class="footerProperty">
<div class="upcomingSchedule">
<h4 class="upcomingSchedule-heading">{{ $data4page->h4Ttle }}</h4>
</div>
</footer>
</aside>
</div>
<div class="content content--withSidebar">
<div class="lead--Home">
<p>{{ $data4page->description }}</p>
</div>
</div>
</main>
#endsection
You have a name mismatch.
return view('content.show')->with(['name' => $data4page]);
Here you should use:
<h1>{{ $name->h4Ttle }}</h1>
As you called it name
In your other options you defined Data4page and in your view you use data4page (lower case d).
Changed this
return view('content.show')->with(['name' => $data4page]);
To:-
return view('content.show')->with(compact('data4page'));
Hope it hepls!
Why have you resorted to typing the variable name with the wrong case when the answers given below are absolutely fine? PHP variables are case sensitive. You're passing $Data4page to your view in the code you've shown and then trying to use the access $data4page. Any of the below will work.
return view('content.show', ['data4page' => $data4page]);
return view('content.show', compact('data4page'));
return view('content.show')->with('data4page', $data4page);
return view('content.show')->with(['data4page' => $data4page]);
return view('content.show')->with(compact('data4page'));
You need to loop through the collection to get the value
#section('content')
<div class="app-template">
<main class="wrapperMain">
#foreach ($data4page as $d4p)
<div class="">
<aside class="navSidebar">
<nav class="navProperty">
<h1 class="navProperty-title">{{ $d4p->h1Ttle }}</h1>
</nav>
<footer class="footerProperty">
<div class="upcomingSchedule">
<h4 class="upcomingSchedule-heading">{{ $d4p->h4Ttle }}</h4>
</div>
</footer>
</aside>
</div>
<div class="content content--withSidebar">
<div class="lead--Home">
<p>{{ $d4p->description }}</p>
</div>
</div>
#endforeach
</main>
#endsection
My Controller:
class Comments extends Controller {
public function GenerateComments($id){
$theme = DB::table('New_Themes')
->where('id', $id)
->get();
$Comments = NewTheme_Comment::where('id_theme', $id)->get();
return view('comments', ['Themes'=>$theme, 'Comments'=>$Comments]);
}
My Table(NewTheme_Comment):
id
parent_id
id_theme
user
text
upVotes
downVotes
My view(contains the recursive display of the tree of comments like the same in reddit), ......(data) contains the bootstrap media object, and the </div>'s things are used to round up (visually) the tree of comments as it should be:
<?php
tree($Comments, 0, 0);
$var = -1;
function tree($Comments, $parent_id = 0, $level=0, $c=0) {
global $var;
foreach($Comments as $Comment) {
if($Comment['parent_id'] == $parent_id) {
If ($level > $var) $var++; else {
for ($i = $var-$level+1; $i>0; $i--) { if ($c < 0) echo '</div> </div>'; else $c--; };
$var=$level;
};
echo '........(data)';
tree($Comments, $Comment['id'], $level+1,$c);
};
};
};
?>
The problem is that .........(data) should contain this stuff:
<div class="media">
<div class="media-left">
<img class="media-object" style="height:40px; width:40px;" src="{{ URL::asset("images/upVote.svg") }}" >
<div>{{$Comment->upVotes-$Comment->downVotes}}</div>
<img class="media-object" style="height:40px; width:40px;" src="{{ URL::asset("images/downVote.svg") }}" >
</div>
<div class="media-body">
<p class="media-heading">{{ $Comment->text }}</p>
<p class="media-heading">{{ $Comment->user }} / {{ $Comment->created_at }} </p>
And I am using the blade above this line | , which I can't integrate into that echo in view, replacing the ..........(data).
I have the intuition that the function I should integrate into the controller but I am broken(I spent to much time on recursive method of displaying comments) and I don't know how to take the data and print out it as whole unit recursively.
Any help is GREATLY appreciated to find a way out of this mess, thank you very much
Edit 1:
This is an example if i am filling with bootstrap media object in ........(data):
<div class="media">
<a class="media-left" href="#">
<img class="media-object" src="..." alt="...">
</a>
<div class="media-body">
<h4 class="media-heading">Media heading</h4>
Without 2 x </div>
You are approaching the views in a wrong way, as blade templates are not meant to use functions, it's better to follow the below recommendations.
The best way for that is to place the function code inside a blade file, for example recursive.blade.php:
recursive.blade.php
#foreach($comments as $comment)
//place your code here
#endforeach
Then in your main blade you can call it several times:
main.blade.php
<div>
#include('recursive', ['comments' => $comments])
</div>
The below example works for me and is the most widely used approach. remember the default value for parent_id is -1.
Model
public function children(){
return $this->hasMany(self::class,'parent_id','id')->with('children');
}
Controller
$comments = Comments::where('parent_id','=',-1)->get();
return view('comments',['comments'=> $comments]);
Blade (comments.blade.php)
<div class="tree">
#include('comment-list-widget',['comments' => $comment])
</div>
Blade (comment-list-widget.blade.php)
<ul>
#foreach($comments as $comment)
<li>
<a>{{$comment->text}}</a>
#if(!empty($comment->children) && $comment->children->count())
#include('comment-list-widget',['comments' => $comment->children])
#endif
</li>
#endforeach
</ul>
