Laravel 5 Pagination: Multiple Paginations in the same Page

In this note I write down my experience regarding multiple paginationin the same page using Laravel 5:

In your laravel controller:

//  Program Degree
$object1s = Object1::orderBy('name', 'desc')
                    ->paginate(2, ['*'], 'page_1s');

// Master Program
$object2s = Object2::orderBy('name', 'desc')
                    ->paginate(2, ['*'], 'page_2s');

// Online Course
$object3s = Object3::orderBy('name', 'desc')
                    ->paginate(2, ['*'], 'page_3s');

In your laravel view:

  // Nothing to change in the view

Now you will have following paginated urls in your application:

1. http://localhost:8000/yourpage?page_1s=2
2. http://localhost:8000/yourpage?page_2s=2
3. http://localhost:8000/yourpage?page_3s=2
4. for special purpose you can custom url to handle all paginations in same time become:
   1. http://localhost:8000/yourpage?page_1s=2&page_2s=3&page_3s=4

Using Switch Case on Laravel 5 Blade

In this post I will show you about how to add Switch Case to Laravel 5.x blade template engine.

Source: Link

On app/Providers/AppServiceProvider.php do following steps:

use Illuminate\Support\Facades\Blade;

On function function boot() add following line:

// Switch case directive
Blade::extend(function($value, $compiler){
    $value = preg_replace('/(\s*)@switch\((.*)\)(?=\s)/', '$1<?php switch($2):', $value);     $value = preg_replace('/(\s*)@endswitch(?=\s)/', '$1endswitch; ?>', $value);
    $value = preg_replace('/(\s*)@case\((.*)\)(?=\s)/', '$1case $2: ?>', $value);
    $value = preg_replace('/(?<=\s)@default(?=\s)/', 'default: ?>', $value);
    $value = preg_replace('/(?<=\s)@breakswitch(?=\s)/', '<?php break;', $value);
    return $value;
});

And now you can use following blade notation to make switch case condition.

@switch($k)
    @case(0)
        fsdfsdf
        @breakswitch
    @case(1)
      sdfsdf
        @breakswitch
    @case(2)
        sdf
        @breakswitch
@endswitch

Set up – Install Laravel5 on Ubuntu

1. composer create-project laravel/laravel BelajarTest –prefer-dist
2. cd BelajarTest
3. test runs several command
   1. ./artisan (if not work do this :  $sudo chmod +x ./artisan )
   2. ./vendor/phpunit (if not work do this :  $sudo chmod +x./vendor/phpunit )
4. now run ./artisan serve
5. open browser and open localhost:8000

I just learned Laravel 5 on my Ubuntu 14.04 laptop, and I got this error message “Segmentation fault (core dumped)” after I ran and open 127.0.0.1:8000 / localhost:8000 in browser. to solve this error “Segmentation fault (core dumped)” just do following steps:

1. rm ./vendor/compiled.php
2. composer update
3. re-run server by executing ./artisan server
4. go to browser open 127.0.0.1:8000/localhost:8000, now everything just work correcly.

ok, that are how to solve error “Segmentation fault (core dumped)” in laravel 5

Or:

composer dump-autoload

composer update

./artisan cache:clear

Eclipse ( Luna ) XDebug configuration

Eclipse + XDebug configuration

Run Server

Laravel update 4.1 to 4.2 error

$ php artisan key:generate

Laravel 4 return wrong id after join table

To solve this we could add a select clause to only select the specific columns:

$exams = Exam::select(‘exams.*’)->where(function($query){
$user = Sentry::getUser();
if (!$user->hasAnyAccess([‘admin’])) {
$query->where(‘user_id’, ‘=’, $user->id);
}
})->join(‘exams_questions’,function($join) use ($question_id) {
$join->on(‘exams_questions.exam_id’, ‘=’, ‘exams.id’)
->where(‘exams_questions.question_id’, ‘=’, $question_id);
})->with(array(‘user’, ‘exam_questions’))->paginate(10);
