To get values from more than two tables in Laravel, you can use Laravel's Eloquent ORM which provides an easy and efficient way to interact with multiple database tables. Here is an example of how you can get values from more than two tables:
- Define the relationships between the tables in your Eloquent models:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
// User model
namespace App;
use IlluminateDatabaseEloquentModel;
class User extends Model
{
public function posts()
{
return $this->hasMany('AppPost');
}
}
// Post model
namespace App;
use IlluminateDatabaseEloquentModel;
class Post extends Model
{
public function comments()
{
return $this->hasMany('AppComment');
}
}
|
- Use Eloquent query to retrieve data from multiple tables:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
// Controller
namespace AppHttpControllers;
use AppUser;
use AppPost;
use AppComment;
class UserController extends Controller
{
public function getUserData($userId)
{
$user = User::find($userId);
// Get user's posts
$posts = $user->posts;
foreach ($posts as $post) {
// Get post's comments
$comments = $post->comments;
foreach ($comments as $comment) {
// Access comment data
echo $comment->text;
}
}
}
}

In the above example, we first retrieve the User model by its ID. Then, we access the user's posts using the posts relationship. For each post, we access the post's comments using the comments relationship.
This way, you can retrieve data from multiple tables in Laravel by utilizing Eloquent relationships.
