I have defined variable in blade template but it is not working. I am not getting any value of i. The column is blank.
<thead style='background-color:silver'><tr><td>S.N.</td><td>Name</td><td>Telephone No.</td><td>Mobile No.</td><td width="24%">Options</td></tr></thead>
<?php $i=1;?>
#foreach ($lists as $li)
<tr><td><?php $i++;?></td><td>{{$li->Name}}</td><td>{{$li->Telephone}}</td><td>{{$li->mobile}}</td>
<td><button>View details</button>
<button>Edit</button>
<button>Delete</button></td></tr>
#endforeach
{!! $lists->render() !!}
This code will definitely work:
<?php $i = 1; ?>
....
<?php $i++; ?>
....
{{-- This will output 2 --}}
{{ $i }}

I've just started using the framework. In plain PHP after the opening foreach I would then set the variables then close the php tag but then from what I can work out you have to then do the Laravel #foreach tags and then open and close #php. Is there a way around this as it seems like a lot of extra work and code?
#foreach($steps as $row)
#php
$title = $row->title;
$text = $row->text;
$i = 1;
#endphp
<div class="steps-item grid-wrap">
<div class="number"
#if($text || $title)
<div class="text-wrap">
#if($title)
<h2>{{$title}}</h2>
#endif
{!! $text !!}
</div>
#php
$i++;
#endphp
#endif
</div>{{--END steps-item--}}
#endforeach
Since blade is no PHP, you have to return to PHP with that directive. But you can set/use the variables without doing that in your case:
#foreach($steps as $i => $row)
<div class="steps-item grid-wrap">
<div class="number"
#if($text || $title)
<div class="text-wrap">
#if($title)
<h2>{{ $row->title }}</h2>
#endif
{!! $row->text !!}
</div>
#php
$i++;
#endphp
#endif
</div>{{--END steps-item--}}
#endforeach
If you still want to set variables, there's a Laravel package called alexdover/blade-set. But as #brombeer pointed out, in most cases it's highly recommended to set all necessary variables in the controller before passing them to the view.
Use laravel provided loop variables:
$loop->iteration The current loop iteration (starts at 1).
It will increment in every loop iteration automatically.
e.g:
First iteration = $loop->iteration => 1 ;
Second iteration = $loop->iteration => 2 ;
so on until loop ends.
Check docs:
The Loop Variables
You can use a #for directive with sizeof($steps) like that:
#for($i=0; $i<= sizeof($steps)-1; $i++)
#endfor
#foreach ($steps as $row)
<div class="steps-item grid-wrap">
<div class="number">
<div class="text-wrap">
#if ($row->title != '')
<h2>{{$row->title}}</h2>
/* if you want to display another title when its blank you can
use if-else here otherwise not need to use if conditions for
title and text */
#endif
#if ($row->text != '')
{!! $row->text !!}
#endif
</div>
</div>
</div>
#endforeach
{{--
for an example you have $steps values like
$steps =
Array(
[0] -> 1,
[1] -> 'title',
[2] -> 'text'
);
if you want this array key value pair you have to use #foreach like
#foreach ($steps as $key=>$value)
#endforeach
you can use key value in #foreach loop only

i would like to know how to do in blade to have the equivalent of this code. I need to do an iteration inside a foreach . i see the blade loop variable like $loop->index or $loop->remaining but I need to know how to use it to make the equivalent of the code below.
<?php
for( $i = 0 ; $i < 3 ; $i++ ) {
$result[$i]['id'];
$result[$i]['name'];
$result[$i]['email'];
}
?>
Thank for any help
Thank mhrabiee. i found the solution.
#foreach($things as $thing)
#if( $loop->first or $loop->iteration <= 3 )
<tr>
<td>{{$thing)->id}}</td>
<td>{{$thing)->name}}</td>
<td>{{$thing)->email}}</td>
</tr>
#endif
#endforeach
this start first iteration
$loop->first
and this stop iteration after 3 loop
$loop->iteration <= 3
and voila !
Your question is a bit vague but exact equivalent of your code is something like this:
#for ($i = 0; $i < 3; $i++)
{{ $result[$i]['id'] }}
{{ $result[$i]['name'] }}
{{ $result[$i]['email'] }}
#endfor
By the way if you want to iterate through something like $results array you can do this:
#foreach ($results as $result)
<div>{{ $result->id }}</div>
<div>{{ $result->name }}</div>
<div>{{ $result->email }}</div>
#endforeach
PS: You can learn more about for loops in Laravel's Blade Documentation.
I try like this :
<div class="media-body">
#foreach($categories as $category)
#php $category[] = $category->name #endphp
#endforeach
{{ implode(",", $category) }}
</div>
If the code executed, there exist error :
undefine variable category
How can I solve it?
You can simply use Laravel Collection
{{ $categories->pluck('name')->implode(', ') }}
Or if you wanna do this in foreach then
#php ($names = [])
#foreach ($categories as $category)
#php ($names[] = $category->name)
#endforeach
{{ implode(', ', $names) }}
You have to declare an array within <?php ... ?> block and then use the same in a {{blade}} block.
I'm having issues on displaying my data from foreach loop. I have 400+ thumbs on my database but laravel doesn't not work correctly, and my footer template didn't display too. I will put my code below.
#foreach($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 method to get an author and display it on a form. It also retrieves the number of quotes attributed to that author. Being pedantic I do not wish to have "1 quotes" so I wrote the following in my layout:
#extends('layouts.dashboardmaster')
$quotetext = "quotes";
if ( $quotes == 1)
{ $quotetext = "quote"; }
#section('pageheading')
<div class="well">
<h2><i class = "fa fa-quote-left"></i> edit author ({{$author->author}}), ({{ number_format($quotes,0) }} {{}}$quotetext }}) </h2>
</div>
#endsection
but I am now getting an error saying
Undefined variable: quotetext
It is clearly defined and I have also tried replacing {{ with
What am I doing wrong?
needs to be
<?php $quotetext = "quotes";
if ( $quotes == 1)
{ $quotetext = "quote"; }
?>
Your view needs to look like this:
#extends('layouts.dashboardmaster')
<?php $quotetext = "quotes"; ?>
#if($quotetext == 1)
<?php $quotetext = "quote"; ?>
#endif
#section('pageheading')
<div class="well">
<h2><i class = "fa fa-quote-left"></i> edit author ({{$author->author}}), ({{ number_format($quotes,0) }} {{$quotetext }}) </h2>
</div>
#endsection
you didn't put php codes in <?php tag.
put them in php tag and everything will be fine
<?php
$quotetext = "quotes";
if ( $quotes == 1){
$quotetext = "quote";
}
?>
from the docs https://laravel.com/docs/5.2/blade
{{ isset($name) ? $name : 'Default' }}
so
{{ isset($quotetext) ?: "quotes" }}
#if ($quotes == 1)
{{ $quotetext = "quote"; }}
#endif
but i think u will get an error about $quotes aswell, anyway remember this is blade not normal php
Use localization provided by Laravel. See Laravel Docs for more information.
Just as an example, add this to your language file (for example resources/lang/en/lang.php
return [
'quote' => 'quote|quotes',
]
Then use this in your view:
{{ trans_choice('lang.quote', $count) }}
