I have a dataset like below inside a cell named rolls.
[
"142650",
"142651",
"142603",
"142604"
]
I have an array named $rooms, where each room has cell called rolls.
#foreach($rooms as $room)
{{ $room->rolls }}
#endforeach
The code above displaying data like below in view
["142650", "142651", "142603", "142604", "142605"]
But I want to display like below...
142650, 142651, 142603, 142604, 142605
I have tried this
#foreach($rooms as $room)
#foreach($room->rolls as $roll)
{{ $roll }}
#endforeach
#endforeach
But getting error like below
Invalid argument supplied for foreach()
I think the cleanest solution, without changing controller is
#foreach($rooms as $room)
<h1>{{ $room->name }}</h1>
#foreach(json_decode($room->rolls) as $roll)
{{ $roll }}
#endforeach
#endforeach
Try not to use #php or <?php ?> in your blade templates
This is the solution I have found, I have not changed anything in my controller, this is what I have done in the view.
#foreach($rooms as $room)
<h1>{{ $room->name }}</h1>
<?php $rolls = json_decode($room->rolls); ?>
#foreach($rolls as $roll)
{{ $roll }}#if(!$loop->last), #endif
#endforeach
#endforeach

I try to ech the object of a laravel many-to-many relation in blade:
When I try to find the created_at with $product->id=47 and echo it out like so:
{{ $inquiry->products->find($product->id)->created_at }}
I get the error: "Trying to get property 'created_at' of non-object..."
When I remove the $product->id and change it to "47" everything works find:
{{ $inquiry->products->find(47)->created_at }}
But I need to query with the variable $product->id.
Any ideas what's wrong here?
Here is a longer part of my code:
#foreach ($upgrades as $upgrade)
{{ $upgrade->id }} //Echos exactly as 47
//List all upgrades
<select>
#if($inquiry->products->where('id', $upgrade->id)->count() == 1)
<option> {{ $inquiry->products->find($upgrade->id)->pivot->duration }}
#endif
</select>
#endforeach
When I try to use $student->links() I see this error :
Facade\Ignition\Exceptions\ViewException
Call to undefined method App\Student::links()
I checked the controller, model etc but all of them seem OK... How can I fix this?
(I tried this code both on my Macbook and VPS -CentOS7- but same problem occurs)
That part of my view looks like this:
</tr>
#endforeach
</tbody>
</table>
{{ $student->links() }}
</div>
#endsection
Change
{{ $student->links() }}
to
{{ $students->links() }}
(use plural form).
You need to paginate in your backend code. $students = App\Student::paginate(15);
And then you can access the links()
<div class="container">
#foreach ($students as $student)
{{ $student->name }}
#endforeach
</div>
{{ $students->links() }}
I have a controller which gets an array of a User's diaries from my database and passes them to my view:
<?php
public function readDiaries($hash)
{
$user = User::where('hash', $hash)->first();
$diaries = Diary::where('user_id', $user->id)->get();
return view('app.diary.readDiaries', ['diaries' => $diaries]);
}
In my view, I am looping through the diaries using a #foreach loop.
<div id="diaries" class="card-columns">
#if (count($diaries) > 0)
#foreach ($diaries as $dairy)
{{ var_dump($diary) }}
#endforeach
#endif
</div>
But I am getting the following undefined variable error...
Undefined variable: diary (View: C:\xampp\htdocs\personal_projects\Active\diary_app\resources\views\app\diary\readDiaries.blade.php)
Why is my $diary variable undefined inside the #foreach loop?
You have a typo
change #foreach ($diaries as $dairy) to #foreach ($diaries as $diary)
and it should work!
There is some typo in var_dump use {{ var_dump($dairy) }}
Try to use compact method for pass data to view as shown below
//return view('app.diary.readDiaries', compact('diaries'));
public function readDiaries($hash)
{
$user = User::where('hash', $hash)
->first();
$diaries = Diary::where('user_id', $user->id)
->get();
return view('app.diary.readDiaries', compact('diaries'));
}
It is just a simple spelling mistake,
#foreach ($diaries as $dairy)
{{ var_dump($diary) }}
#endforeach
in your foreach you are passing $dairy and dumping var name is $diary
chane it to
#foreach ($diaries as $dairy)
{{ var_dump($dairy) }}
#endforeach
Habbit of copy paste is sometimes good for us...
:)
#foreach ($diaries as $dairy)
{{ var_dump($diary) }}
#endforeach
you used ($diaries as $dairy) in foreach
but in foreach you used ($diary)
you want edit this {{ var_dump($diary) }} to {{ var_dump($dairy) }}
or you want edit #foreach ($diaries as $dairy) to #foreach ($diaries as $diary)
I'm having issues on displaying my data from foreach loop. I have 400+ thumbs on my database but laravel doesn't not work correctly, and my footer template didn't display too. I will put my code below.
#foreach($thumbs as $thumb)
{{$thumb['name']}}
{{$thumb['desc']}}
{{$thumb['place']}}
#endforeach
myfooter code goes here.
from my controllers
$data['thumbs'] = thumb::all();
return View('tubetour/home',$data);
but when I tried to var_dump or return the value of thumbs on my controller
it displays all my 400+ data.
$data['thumbs'] = thumb::all();
return $data['thumbs'];
You need to pass an associative array as a second argument to the view function:
// Controller
$thumbs = Thumb::all();
return \View::make('tubetour.home', ['thumbs' => $thumbs]);
// View
#foreach($thumbs as $thumb)
{{ $thumb->name }}
{{ $thumb->desc }}
{{ $thumb->place }}
#endforeach
Edit: if you are using laravel 4 you will need to use View::make()
If Thumb is an Eloquent model, then the Thumb::all() will return an Eloquent collection, not an array. In that case you have to update your blade template like so:
#foreach($thumbs as $thumb)
{{ $thumb->name }}
{{ $thumb->desc }}
{{ $thumb->place }}
#endforeach
Hope this solve your issue.
UPDATE
Pass the $thumbs as an array and display it as table.
Update your controller like this:
$data['thumbs'] = thumb::all()->toArray();
return View('tubetour/home', $data);
And your view like this, see how many rows being displayed.
<table>
<thead>
<tr>Id</tr>
<tr>Name</tr>
<td>Desc</td>
<td>Place</td>
</thead>
<tbody>
#for ($i = 0; $i < count($thumbs); $i++)
<tr>
<td>{{ $i }}</td>
<td>{{ $thumbs[$i]['name'] }}</td>
<td>{{ $thumbs[$i]['desc'] }}</td>
<td>{{ $thumbs[$i]['place'] }}</td>
</tr>
#endfor
</tbody>
</table>
UPDATE 2
Blade template example with bootstrap grid:
<div class="row">
#for ($i = 0; $i < count($thumbs); $i++)
<div class="col-md-4">
<img src="img/sample.jpg">
<h3>{{ $thumbs[$i]['name'] }}</h3>
{{ $thumbs[$i]['desc'] }}
</div>
#endfor
</div>
try this
#foreach($data as $thumb)
{{$thumb['name']}}
{{$thumb['desc']}}
{{$thumb['place']}}
#endforeach
Update your controller
$data = Thumb::all();
return View::make('tubetour/home')->with("thumbs",$data)
->render();
Then your view with this:
#foreach($thumbs as $thumb)
{{$thumb['name']}}
{{$thumb['desc']}}
{{$thumb['place']}}
#endforeach
I have a #foreach loop in the Blade template and need to apply special formatting to the first item in the collection. How do I add a conditional to check if this is the first item?
#foreach($items as $item)
<h4>{{ $item->program_name }}</h4>
#endforeach`
Laravel 5.3 provides a $loop variable in foreach loops.
#foreach ($users as $user)
#if ($loop->first)
This is the first iteration.
#endif
#if ($loop->last)
This is the last iteration.
#endif
<p>This is user {{ $user->id }}</p>
#endforeach
Docs: https://laravel.com/docs/5.3/blade#the-loop-variable
SoHo,
The quickest way is to compare the current element with the first element in the array:
#foreach($items as $item)
#if ($item == reset($items )) First Item: #endif
<h4>{{ $item->program_name }}</h4>
#endforeach
Or otherwise, if it's not an associative array, you could check the index value as per the answer above - but that wouldn't work if the array is associative.
Just take the key value
#foreach($items as $index => $item)
#if($index == 0)
...
#endif
<h4>{{ $item->program_name }}</h4>
#endforeach
As of Laravel 7.25, Blade now includes a new #once component, so you can do it like this:
#foreach($items as $item)
#once
<h4>{{ $item->program_name }}</h4> // Displayed only once
#endonce
// ... rest of looped output
#endforeach
Laravel 7.* provides a first() helper function.
{{ $items->first()->program_name }}
*Note that I'm not sure when this was introduced. So, it may not work on earlier versions.
It is only briefly mentioned in the documentation here.
The major problem with Liam Wiltshire's answer is the performance because:
reset($items) rewind the pointer of $items collection again and again at each loop... always with then same result.
Both $item and the result of reset($item) are objects, so $item == reset($items) requires a full comparison of its attributes... demanding more processor time.
A more efficient and elegant way to do that -as Shannon suggests- is to use the Blade's $loop variable:
#foreach($items as $item)
#if ($loop->first) First Item: #endif
<h4>{{ $item->program_name }}</h4>
#endforeach
If you want to apply a special format to the first element, then maybe you could do something like (using the ternary conditional operator ?: ):
#foreach($items as $item)
<h4 {!! $loop->first ? 'class="special"': '' !!}>{{ $item->program_name }}</h4>
#endforeach
Note the use of {!! and !!} tags instead of {{ }} notation to avoid html encoding of the double quotes around of special string.
Regards.
if you need only the first element you can use #break inside your #foreach or #if.see example:
#foreach($media as $m)
#if ($m->title == $loc->title) :
<img class="card-img-top img-fluid" src="images/{{ $m->img }}">
#break
#endif
#endforeach
you can do it by this way.
collect($users )->first();
To get the first element of a collection in Laravel, you can use :
#foreach($items as $item)
#if($item == $items->first()) {{-- first item --}}
<h4>{{$item->program_name}}</h4>
#else
<h5>{{$item->program_name}}</h5>
#endif
#endforeach
