Laravel ViewErrorBag Public API: hasBag

By John Koster

hasBag($key = 'default')

The hasBag method is used to determine if a MessageBag instance exists within the ViewErrorBag instance with the given $key. The $key is set to default unless it is changed. The following example will highlight the usage of the hasBag method.

 1<?php

 2

 3use Illuminate\Support\ViewErrorBag;

 4use Illuminate\Support\MessageBag;

 5

 6// Create a new ViewErrorBag instance.

 7$viewErrorBag = new ViewErrorBag;

 8

 9// Check if the 'default' MessageBag instance

10// exists.

11//

12// false

13$doesExist = $viewErrorBag->hasBag();

14$doesExist = $viewErrorBag->hasBag('default');

15

16// Check if a 'payments' MessageBag instance

17// exists.

18//

19// false

20$doesExist = $viewErrorBag->hasBag('payments');

21

22// Add a new 'payments' MessageBag instance.

23$viewErrorBag->put('payments', new MessageBag);

24

25// Check again if the 'payments' MessageBag instance

26// exists.

27//

28// true

29$doesExist = $viewErrorBag->hasBag('payments');
