Laravel Eloquent Query Using WHERE with OR AND OR?

Make use of Logical Grouping (Laravel 7.x/4.2). For your example, it'd be something like this:

Model::where(function ($query) {
    $query->where('a', '=', 1)
          ->orWhere('b', '=', 1);
})->where(function ($query) {
    $query->where('c', '=', 1)
          ->orWhere('d', '=', 1);
});

laravel elequent query

Model::where(function ($query) {
    $query->where('a', '=', 1)
          ->orWhere('b', '=', 1);
})->where(function ($query) {
    $query->where('c', '=', 1)
          ->orWhere('d', '=', 1);
});

Laravel when query

$query = Author::query();

$query->when(request('filter_by') == 'likes', function ($q) {
    return $q->where('likes', '>', request('likes_amount', 0));
});
$query->when(request('filter_by') == 'date', function ($q) {
    return $q->orderBy('created_at', request('ordering_rule', 'desc'));
});

$authors = $query->get();

laravel find query

// Retrieve a model by its primary key...
$flight = AppModelsFlight::find(1);

// Retrieve the first model matching the query constraints...
$flight = AppModelsFlight::where('active', 1)->first();

// Shorthand for retrieving the first model matching the query constraints...
$flight = AppModelsFlight::firstWhere('active', 1);

laravel find query

php artisan make:model Flight --migration

php artisan make:model Flight -m

laravel find query

return Destination::orderByDesc(
    Flight::select('arrived_at')
        ->whereColumn('destination_id', 'destinations.id')
        ->orderBy('arrived_at', 'desc')
        ->limit(1)
)->get();

laravel find query

<?php

namespace AppModels;

use IlluminateDatabaseEloquentModel;

class Flight extends Model
{
    /**
     * The primary key associated with the table.
     *
     * @var string
     */
    protected $primaryKey = 'flight_id';
}

laravel "query()->find"

The find Method
If you are overriding the find method in your own models and calling parent::find() within your custom method, you should now change it to call the find method on the Eloquent query builder:

public static function find($id, $columns = ['*'])
{
    $model = static::query()->find($id, $columns);

    // ...

    return $model;
}

laravel find query

foreach (Flight::where('foo', 'bar')->cursor() as $flight) {
    //
}

laravel query when

$users = DB::table('users')
                ->when($role, function ($query, $role) {
                    $query->where('role_id', $role);
                })
                ->get();

laravel where in query builder

public function index()
{
    $users = User::select("*")
                    ->whereIn('id', [4, 5, 6])
                    ->get();
  
    dd($users);                    
}

LARAVEL QUERY

<?php

Route::get('games', function () {
    
    $games = DB::table('games')->get();
    
    return view('games', ['games' => $games]);
});

laravel find query

$model = AppModelsFlight::where('legs', '>', 100)->firstOr(function () {
        // ...
});

How to write this query in Laravel Eloquent

Visitor::select('country')
     ->withCount('id')
     ->groupBy('country')
     ->latest()
     ->get()
  
  //or
  
  Visitor::query()->groupBy('country')->orderByDesc('count')->select('country' ,DB::raw('COUNT(1) as count'))->get()

laravel find query

<?php

$flights = AppModelsFlight::all();

foreach ($flights as $flight) {
    echo $flight->name;
}

laravel find query

<?php

namespace AppModels;

use IlluminateDatabaseEloquentModel;

class Flight extends Model
{
    /**
     * The connection name for the model.
     *
     * @var string
     */
    protected $connection = 'connection-name';
}

laravel find query

foreach ($flights as $flight) {
    echo $flight->name;
}

Laravel query

//select specified colomns from all users
Employee::get(['name','email','title']);

laravel find query

use AppModelsDestination;
use AppModelsFlight;

return Destination::addSelect(['last_flight' => Flight::select('name')
    ->whereColumn('destination_id', 'destinations.id')
    ->orderBy('arrived_at', 'desc')
    ->limit(1)
])->get();
