I am using the page of Laravel with order by desc and I indicate that 5 elements are displayed.
When returning 7 the first page shows me 2 and the second 5. I want the first one to be filled before the second. If I use ASC it works correctly.
Controller:
public function list(){
$questions = Question::orderBy('id', 'DESC')->paginate(5);
return view('web.pages.list', compact('questions'));
}
Vista:
#foreach ($questions as $q)
<a href="/list/{{$q->category($q->category_id)}}/{{$q->id}}">
<div class="container-list-question">
<div class="header-category-list-question">
<span>{{$q->category($q->category_id)}}</span>
</div>
<div class="data-question">
Autor: {{$q->author}}
</div>
<div class="title-list-question">
<span>{{$q->question}}</span>
<div class="btn-show"> Show question</div>
</div>
</div>
</a>
#endforeach
{{ $questions->links() }}

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.
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.
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>{{ $d4p->description }}</p>
</div>
</div>
#endforeach
</main>
#endsection
I have a page which has a search box(input text) which takes a place name as input and returns all the nearby dealers.
I also happen to have filters (checkboxes) for all the brand
<div class="col-sm-12 col-md-12">
{!! Form::checkbox('filters',$bike_oem, false,['style'=>'padding-right:5px;'] ) !!} <span style="padding-left:5px;"></span>{{ $bike_oem }}
</div>
How do I implement get the value of filter in my controller ?
<div class="col-sm-12 col-md-12">
<input style="padding-right:5px;" name="Hyundai " type="checkbox" value="Y"> <span style="padding-left:5px;"></span>Hyundai
</div>
This is how each filter appears in the page. Is the code correct to fetch the value in controller ? Please suggest
You can get the value of checkbox in this way also(in controller)
public function myFunction(Request $request){
if (isset($request['Hyundai']) && ($request['Hyundai'] == "on")) {
$value = "Y";
}
}
My Controller:
class Comments extends Controller {
public function GenerateComments($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>
