How to Store Data in Pivot Table in Laravel?

In Laravel, you can use the pivot method to access and manipulate the intermediate table data of a many-to-many relationship. To store data in the pivot table, you can follow these steps:

1. Define the many-to-many relationship between your models using the belongsToMany method.

class User extends Model
{
public function roles()
{
return $this->belongsToMany(Role::class)->withPivot('permission');
}
}

class Role extends Model
{
public function users()
{
return $this->belongsToMany(User::class)->withPivot('permission');
}
}

 

2. To store data in the pivot table, you can attach the related models using the attach method, passing an array of additional data as the second argument.

$user = User::find(1);
$role = Role::find(2);

$user->roles()->attach($role, ['permission' => 'read']);

3. You can also update the data in the pivot table using the updateExistingPivot method.

 

$user = User::find(1);
$role = Role::find(2);
$user->roles()->updateExistingPivot($role->id, ['permission' => 'write']);

4. You can retrieve the data stored in the pivot table using the pivot attribute.

$user = User::find(1);
foreach ($user->roles as $role) {
echo $role->pivot->permission;
}

Note: In the example above, we added withPivot method in both belongsToMany relationships to allow us to access the permission field in the pivot table.
