hello people here is my code below for controller
$siteinformation = DB::table('siteinformation')->where('Site',$myarr[0]['site'])->select()->get();
print_R($siteinformation); will display
Array ( [0] => stdClass Object ( [Site] => site1 [Nickname] => friend [ProgramID] => 1 [CreateDateTime] => 2014-06-03 18:05:39 ) )
I am trying to pass it to view
return Redirect::to('sbs_site')->with('siteinformation',$siteinformation);
In my view i have...
#if(Session::has('siteinformation'))
#foreach ($siteinformation as $key => $value)
{{ $value->Nickname }}
#endforeach
#endif
Iam gettng an error Undefined variable: siteinformation
my route file contains... Route::post('sbs_site', array('uses' => 'myController#sys_config'));
what could be the problem??
I think you don't need to redirect; probably you are doing it wrong, instead you should pass the data to the view directly using something like this:
$siteinformation = DB::table('siteinformation')
->where('Site',$myarr[0]['site'])
->get();
// View Name: "sbs_site.blade.php"
return View::make('sbs_site')->with('siteinformation', $siteinformation);
Then in the view:
#foreach ($siteinformation as $value)
{{ $value->Site }}
{{ $value->Nickname }}
#endforeach
But if your really need to use a redirect then you may do it like this:
// Route Is: "sbs_site"
return Redirect::to('sbs_site')->with('siteinformation', $siteinformation);
Then in your view:
#if(Session::has('siteinformation'))
#foreach (Session::get('siteinformation') as $value)
{{ $value->Site }}
{{ $value->Nickname}}
#endforeach
#endif
This worked for me...
in view
#if(Session::has('siteinformation'))
#foreach (Session::get('siteinformation')as $key => $value)
{{ $value->Nickname}}
#endforeach
#endif
In controller
return Redirect::to('sbs_site')->with('siteinformation',$siteinformation);
Your view file is not getting session set if(Session::has('siteinformation')), because you did not set session in your controller. You set in your controller 'siteinformation' as a normal variable. If you want to set session, instead of this.
Redirect::to('sbs_site')->with('siteinformation',$urserializedobj);
Do this
Session::put('siteinformation',$urserializedobj);
Redirect::to('sbs_site');
OR
Simply don't check session in your view instead of this
if(Session::has('siteinformation'))
Just do this
if (!empty($siteinformation)) :
I don't know why u are redirecting to pass it to the view
return View::make('yourview',array('siteinformation'=>$siteinformation));
This will do the trick if you can make the view directly from the controller
BUT
if u need to redirect than i suppose you can serialize your array or change it to json first because the with function passes the data as flash so only strings
$urserializedobj = $siteinformation.toJson();//if this doesn't work try serealizing
return Redirect::to('sbs_site')->with('siteinformation',$urserializedobj );
now in your view you can do this
#if(Session::has('siteinformation'))
$siteInformation = json_decode(Session::get('siteinformation'));
#foreach ($siteinformation as $key => $value)
{{ $value->Nickname }}
#endforeach
#endif

I want to echo arry elemnts in view
followings are my code (controller)
$next_d_dts= \DB::table('tb_billing_cycle')->select('next_due_bill_date')->where('customer_id',$row->customer_id)->get();
return view('invoice.view')->with('next_d_dts',$next_d_dts);
I can print it using print function, eg:
print_r($next_d_dts);
Output:
Array ( [0] => stdClass Object ( [next_due_bill_date] => 2019-03-28 ) [1] => stdClass Object ( [next_due_bill_date] => 2020-02-28 ) )
You need to iterate over the collection of objects:
#foreach ($next_d_dts as $object)
{{ $object->name }}
#endforeach
If you just want to see its contents but not stop the script:
{{ var_dump($next_d_dts) }}
You've also asked how to iterate without Blade:
foreach ($next_d_dts as $object) {
echo $object->name;
}
#foreach($next_d_dts as $value)
{{$value['next_due_bill_date']}}
#endforeach
you should used foreach loop in laravel like this
#foreach ($next_d_dts as $value)
<p>Some text here{{ $value->id }}</p>
#endforeach
for more information read Laravel Manual blade template
Also you can used
dd($next_d_dts) //The dd function dumps the given variables and ends execution of the script
You can convert it into array using toArray() and iterate over it
$next_d_dts= \DB::table('tb_billing_cycle')->select('next_due_bill_date')->where('customer_id',$row->customer_id)->get()->toArray();
In view
#foreach($next_d_dts as $value)
{{ $value['column_name'] }}
#endforeach
Or
print_r($next_d_dts)
#foreach($array as $item)
{{$item}}
#endforeach
Simple.
you need to use Blade Loops syntax invoice.view.blade.php
#foreach($next_d_dts as $next )
{{ $next }}
#endforeach
I am using Youtube package
I added this on app.php
Alaouy\Youtube\YoutubeServiceProvider::class,
&
'Youtube' => Alaouy\Youtube\Facades\Youtube::class,
now i m trying in view like this
{{ Youtube::getVideoInfo('rie-hPVJ7Sw') }}
but getting error
"htmlspecialchars() expects parameter 1 to be string, object given
(View: C:\xampp\htdocs\guru\resources\views\admin\video\index.blade.php)"
how can I fix this?
i Tried
#foreach($videos as $video)
{{ var_dump(Youtube::getVideoInfo($video->videoid)) }}
#endforeach
its showing me everything
Here is Screenshot
As per the docs,
// Return an STD PHP object
$video = Youtube::getVideoInfo('rie-hPVJ7Sw');
so you could do,
{{ var_dump(Youtube::getVideoInfo('rie-hPVJ7Sw')) }}
to print out the object or assign it to a variable and access the respective object properties
EDIT
To show only the embed html you could use the following code
#foreach($videos as $video)
{!! Youtube::getVideoInfo($video->videoid)->player->embedHtml !!}
#endforeach
I have created notification to store order submit event as
return [
'cart_id'=>$this->cart->id,
'text'=>'order is submitted'
];
when i retrieve notifications data from database as
#foreach (Auth::user()->unreadNotifications as $notification )
{{$notification->data['text'] }}
#endforeach
this gives error as undefined index text
but if i try to access text via
#foreach ($notification->data as $key => $data)
{{$data}}
#endforeach
it works
but why cant i can access data via $notification->data['text']
You should get the text attribute directly like :
#foreach (Auth::user()->unreadNotifications as $notification )
{{ $notification->text }}
//Or use
{{ $notification['text'] }}
#endforeach
Hope this helps.
I have a edit form with some checkboxes that I am trying to make checked when the associated many to many relationship is established.
Distributors belong to many beers
Beers belong to many distributors
in my controller I have:
$breweries = Brewery::lists('name', 'id');
$all_dist = Distributor::all();
$beer = Beer::find($id);
$distributions = [];
foreach ($beer->distributors as $distributor)
{
$distributions[$distributor->id] = BeerDistribution::where('beer_id', '=', $beer->id)
->where('distributor_id', '=', $distributor->id)->first()->price;
}
return View::make('beers.edit', ['beer' => $beer, 'distributors' => $all_dist, 'distributions' => $distributions, 'breweries' => $breweries, 'styles' => $styles]);
and I in my edit form I have:
{{ Form::model($beer, ['route' => ['beers.update', $beer->id], 'method' => 'PATCH']) }}
#foreach ($distributors as $distributor)
<?php $carried = in_array($distributor->id, array_keys($distributions)) ? true : false ?>
{{ Form::checkbox('distributors[]', $distributor->id, $carried); }}
{{ Form::label($distributor->name) }}
{{ Form::label('price' . $distributor->id, 'Retail:') }}
<?php $price = $carried ? $distributions[$distributor->id] : null ?>
{{ Form::text('price' . $distributor->id, $price ) }}
#endforeach
{{ Form::submit('Save') }}
{{ Form::close() }}
Basically I am passing an associated array of each distributor_id => price. This array also tells me which distributors the beer already belongs to so that I can mark those checked off in my edit form.
Here's where things get wonky. When I load this form, all the checkboxes will be checked no matter what. If I change my controller loop to this:
foreach ($beer->distributors()->lists('distributor_id') as $distributor_id)
Then I can do create my array.
Why does calling $beer->distributors in the controller would result in all the checkboxes being checked?
The problem is with the last argument : $carried
{{ Form::checkbox('distributors[]', $distributor->id, [ "checked" => $carried ]); }}
Pass the last parameter as array, and tell it exactly which attribute to modify and the attribute value.
I have a problem and I can't resolve it, please help me. So I have my form :
{{ Form::open(array('url'=>'/administration/student/addMarks','method' => 'post')) }}
#foreach($aObjectsInGroupe as $object)
{{ Form::hidden('id_object[]',$object->id) }}
{{ Form::label($object->name) }}
{{ Form::select('note[]', $aMarks, null, array('class'=>'form-control')) }}
<br />
#endforeach
{{ Form::hidden('id',$aOneStudent['id']) }}
{{ Form::submit('Add mark',array('class'=>'btn btn-primary')) }}
{{ Form::close() }}
In my StudentController I have a method for get the mark from student_id and object_id:
public function getMarkByStudentAndObject($nIdStudent, $nIdObject){
$aMark = \Mark::where('student_id', '=', $nIdStudent)
->and('object_id', $nIdObject)
->get()
->toArray();
}
$aMarsks it's a table :
$aMarks = array(
'0'=>'0',
'1'=>'1',
'2'=>'2',
'3'=>'3',
'4'=>'4',
'5'=>'5',
'6'=>'6',
'7'=>'7',
'8'=>'8',
'9'=>'9',
'10'=>'10',
);
It's possible to call the method getMarkByStudentAndObject in :
{{ Form::select('note[]', $aMarks, null, array('class'=>'form-control')) }}
to get the selected value?
Help me please. Thx in advance.
maybe you need to do this:
<select name="note[]" class="form-control">
#foreach($aMarks as $key => $value)
<option value="{{ $key }}">{{ $value }}</option>
#endforeach
</select>
You should also check your Eloquent query, instead of ->and use another ->where
Try the lists() function of the Query Builder
\Mark::where('student_id', '=', $nIdStudent)
->and('object_id', $nIdObject)
->lists('column_1', 'column_2');
You then get the values of column_1 as the keys of the array and column_2 as the values.
http://laravel.com/docs/4.2/queries#selects
You should be able to directly call this from the Form::select. A call to
Mark::getMarkByStudentAndObject($aOneStudent['id'], $object->id)->note
would give you the Mark object and then you would need to get the note column which stores the value in the Mark object. Resulting in a call like this:
{{
Form::select(
'note[]',
$aMarks,
Mark::getMarkByStudentAndObject(
$aOneStudent['id'],
$object->id
)->note, array('class'=>'form-control')
)
}}
At the moment I can't verify if this is working because I have no possibility to test it but it should work as Blade is just a wrapper for PHP calls.
