How to Fix Undefined Offset: 0 in Laravel Blade

laravel Undefined offset: 0

It might be that you are using a get, using post might help. Other than that you are mixing model and controller code. It's always a good idea to seperate these. For instance your redirects should be done inside the controller and not in the model.

• http://laravel.com/docs/validation
• http://laravelbook.com/laravel-input-validation/
• http://culttt.com/2013/07/29/creating-laravel-4-validation-services/

It's also better to do stuff on $validator->passes() and then else return with errors.

Controller

public function store() {

    $data = [
       "errors" => null
    ];

    $rules = array(
        'car' => array('required', 'unique:insur_docs,car_id')
    );

    $validation = Validator::make(Input::all(), $rules);

    if($validation->passes()) {
        $data = new InsurDoc();
        $data->ownership_cert = Input::get('ownership_cert');
        $data->authoriz = Input::get('authoriz');
        $data->drive_permis = Input::get('drive_permis');
        $data->sgs = Input::get('sgs');
        $data->tpl = Input::get('tpl');
        $data->kasko = Input::get('kasko');
        $data->inter_permis = Input::get('inter_permis');
        $data->car_id = Input::get('car');
        $data->save();
        return Redirect::to('/');
    } else {
        $data['errors'] = $validation->errors();
        return View::make('pages.insur_docs_create', $data);
    }

}

Your errors will be available in your view under $errors. Just do a {{var_dump($errors)}} in your blade template to verify that they are there.

View

@if($errors->count() > 0)
  <p>The following errors have occurred:</p>

  <ul>
    @foreach($errors->all() as $message)
      <li>{{$message}}</li>
    @endforeach
  </ul>
@endif

Index Controller

public function show($slug) {
    $service = Service::where('s_slug', $slug)->first();
    return view('')->with(compact('service'));
}

in Service Blade

<h2 class="font-size-25">{{ $service->s_name}}  </h2>

Undefined offset: 0 in blade Laravel 5.6

I suggest to print the values of $val->u_id into the @foreach to debug your code.

Then the proper way to assign a value to a php variable in blade is using the @php directive.

How to Set Variables in a Laravel Blade Template

https://laravel.com/docs/5.7/blade#php

@foreach($school_data as $val)
    {{$val->u_id}}
    @php ($datas2 = \App\criteria::where('u_id', $val->u_id)->get()) @endphp
    @php (dump($datas2) ) @endphp
    @php ($trck2 = $datas2['0']->updated_by_email) @endphp
@endforeach

Blade returns undefined offset

The error point out that there was a issue while compiling blade file possibly because of syntax error.
So, just wrap the foreach variable inside paranthesis and the issue should be fixed.

@extends('public.layout')

@section('content')
    Companies
    @foreach ($companies as $company)
        {{ $company->title }}
    @endforeach
@stop
