Was wondering if someone could check this out and let me know what I'm doing wrong. I'm trying to use paginate on a database query and render it in my view.
Is my DB query incorrect? I was following the docs to create it. Also read that I needed to remove ->get() when using paginate.
This is what is giving the error on my view: {{$item->paginate(4)}}, same happens if I use {{$item->links(4)}}
Everything renders fine if I remove paginate from the query in the controller..?
Here is what I'm working with.
Controller:
public function index()
{
// $news = DB::table('news')->orderBy('id', 'DESC')->paginate(4);
$news = DB::table('news')->select('id','title','description','listing_image','created_at','updated_at')->orderBy('id', 'DESC')->paginate(4);
return view('news.index',compact('news'));
}
View: (Getting error: Call to undefined method stdClass::paginate())
#if ($news->count())
#foreach($news as $item)
...html
#if ($item->listing_image)
...more html
#else
#endif
... more html
#endforeach
{{$item->paginate(4)}}
#endif
change {{$item->paginate(4)}} to {{ $news->links() }}

Reference: Laravel Eloquent relationship not an object when doing anything but dd()
I am trying to output a Laravel relationship in Blade. However, this, {{ $video->channel->id }} returns a non-object error. But, when dded, like so, {{ dd($video->channel->id) }}, a value is there. I've been pulling my hair so hard because of this... What is going on? Why is there an output only when the variable is dded?
I'm testing on PHP 7.2 with Laravel 5.6. Relationships are established as per Eloquent documentation. I've tried fetching the data like this:
$videos = Video::where('foo', 'bar')->with('channel')->take(100)->get();
and
$videos = Video::where('foo', 'bar')->take(100)->get();
The same thing; same output/error.
$tokens = preg_split("/[\s,]+/", $q);
$videos = Video::with('channel')
->where(function ($query) use ($tokens) {
foreach ($tokens as $token) {
$query->orWhere('title', 'LIKE', "%$token%");
}
})
->take(100)
->get();
// foreach ($videos as $video)
{{ $video->channel->id }} // non-object error
{{ dd($video->channel->id) }} // WORKS! IDK Why...
Trying to get property 'id' of non-object is the actual error log.
EDIT:
Below is an image of the $videos collection fetched from Database.
If in dd(), something gets outputted fine, I can only assume I'm fetching the data right, yea?
As you're doing this in a loop, the error
Trying to get property 'id' of non-object
means that 1 iteration of $video->channel returns a non-object (likely null), and you can't access the property ->id of it (as null doesn't have any properties, etc.)
The reason dd() works is that it's dumping and dieing on the first iteration, which has a channel. To handle this, simply add an #if() clause:
#foreach($videos AS $video)
#if($video->channel)
{{ $video->channel->id }}
#else
...
#endif
...
#endforeach
Or, in the query to get $videos, enforce relationship:
$videos = Video::where('foo', 'bar')->has('channel')->with('channel')->take(100)->get();
This way, $video->channel will not be null.
What is the most effective way for returning data from two tables in on view?
Like an employee check the vehicle for each order.
Route::get('orderVehicle',"adminController#orderVehicle");
public function orderVehicle(Request $reques){
$orders = new Order;
$vehicles = new Vehicle; $orders->id; $vehicles->id; return view('adminVeiw.orderVehicle',compact('orders','vehicles')); }
#foreach($orders as $or) {{ $or->id }} #endforeach {{ $vehicles->id }}
And the error is
"Trying to get property 'id' of non-object (View:
/var/www/html/full-Restaurant-App-Using-Laravel/resources/views/adminVeiw/orderVehicle.blade.php)"
So any suggestions?
do this if you don't wanna change your code in controller
#foreach($orders as $or)
#if(!empty($or->id))
{{ $or->id }}
#endif
#endforeach
#if(!empty($vahicles->id))
{{ $vehicles->id }}
#endif
in this case you won't get error but i don't know how you wanna this works for you,
i hope it helps
public function orderVehicle()
{
$orders = Order::create();
$vehicles = Vehicle::create();
return view('adminVeiw.orderVehicle', compact('orders', 'vehicles'));
}
I need to get each comment of news . Its working good for firstorFail() item
{{$news->comments()->firstOrFail()->name}}
But bring me empty result when im try this one with foreach:
#foreach($news->comments() as $comment)
{{$comment->name}}
#endforeach
The function firstOrFail will return exactly one comment. Seems like you actually want all comments? You should use this in your controller
$news->comments; // yeah that's it, it will load all comments
Also return news
return view('my.view', compact('news'));
Then use it in blade
#foreach($news->comments as $comment)
{{$comment->name}}
#endforeach
the line
$news->comments()
would require you to also call ->get() , because comments() will return the relation instead of the actual data.
This: $news->comments() bringing you query builder probably. So what you need is to ->get() for execute query like this:
#foreach($news->comments()->get() as $comment)
{{$comment->name}}
#endforeach
Edit
or as a #Roy Philips mentioned: $news->comments
I need to find out unique value. So I tried bellow code. It is through undefined variable error.
Controller:
$employee = Employee::all();
Return view ('page', compact('employee'));
Page view:
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
#Foreach($uniqueEmpLoc as $empLoc)
{{ $empLoc }}
//this is select box used for search
#endforeach
//Display Entire data
#foreach($employee as #employee)
//Display all value
#endforeach
But I got an uniqueEmpLoc is undefined error. I'm using LARAVEL 5.1. Please help me to solve this problem.
There are some errors in your code:
I don't think compact(employee) would work. Shouldn't that suppose to be compact('employee') ?
In Blade, there is no need of putting curly braces at all. Remove them.
Try out the following:
$employees = Employee::unique('locations')->values()->list('location')->toArray();
return view('page', compact('employees'));
And then in your view:
#foreach($employees as $employee)
{{ $employee }}
#endforeach
Use this query in controller
$employees = Employee::distinct()->list('location')->toArray();
return view('page', compact('employees'));
In view
#foreach($employees as $employee)
{{ $employee }}
#endforeach
I agree with the other answers here, this code should be in the controller. You shouldn't be doing logic in the views.
In the controller do:
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
$employee = Employee::all();
Return view ('page', compact('employee', 'uniqueEmpLoc'));
The reason your code isn't working is the line that defines $uniqueEmpLoc is interpreted by blade as text, not code.
If you really want to do that in the view, you need to wrap it in #php tags.
#php
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
#endphp
#Foreach($uniqueEmpLoc as $empLoc)
{{ $empLoc }}
//this is select box used for search
#endforeach
I'm new to Laravel and I'm getting an error which I think has more to do with logic than anything else but I can't quite seem to grasp how to overcome it.
So, I have a page with a simple form to search for a particular string in my database. But I want to have the result show up on the same page.
Here's what I have so far:
This is my Route.php:
Route::get('/', 'HomeController#index');
Route::post('find', 'HomeController#find');
This is my HomeController:
public function index()
{
return View::make('index');
}
public function search()
{
return View::make('index');
}
public function find()
{
$match = Input::get('find');
if($match) {
$results = Book::where('title', 'like', '%'.$match.'%')
->orWhere('author', 'like', '%'.$match.'%')
->get();
return View::make('index', array('results', $results));
} else {
return Redirect::to('/')->with('flash_error', 'No string added!');
}
}
And my View (index.blade.php):
{{ Form::open(array('url' => 'find', 'method' => 'POST')) }}
{{ Form::text('find', '', array('class' => 'search-query', 'placeholder' => 'Search')) }}
{{ Form::submit('Submit', array('class' => 'btn btn-info')) }}
{{ Form::close() }}
#if (Session::has('flash_error'))
{{ Session::get('flash_error') }}
#endif
#foreach ($results as $result)
{{$result->title}}
#endforeach
(eventually the foreach will be replaced by some ajax loading to display each result)
And the error says "undefined variable: results" and shows the foreach.
I get why that error shows up since on the first pass to this page the results haven't been loaded yet but how can I overcome this? I really want the data to be shown on the same page without having to go to another page to display them.
Like I said, I think this is mostly logic related (although I'm very new to Laravel so it might be that too)
Any help would be greatly appreciated !
you need to pass an associative array as your second param of the make method
return View::make('index', array('results' => $results);
The problem here is that in your use of index.blade.php in multiple controllers, you forgot which controllers provide which variables (and as a result, which variables may be omitted).
When you request / (HomeController#index), index.blade.php is rendered, but since no $results are passed to the view, you see the Undefined Variable warning. This is not a problem in HomeController#find, because you define $results. To combat this, you'll need to do something along the lines of an isset() check on $results before you foreach over it. Like so:
#if(isset($results))
#foreach ($results as $result)
{{$result->title}}
#endforeach
#endif
Your logic may vary based on your page's layout (you might want to add an else and display some alternate placeholder content).
Also, if abstracting the call to View::make() with $results into index_gen() isn't keeping your code DRY, then I'd suggest replacing it in find() with the call to View::make().
