Laravel MessageBag Public API: has

By John Koster

has($key = null)

The has method can be used to determine if messages exist within the MessageBag instance for a given $key. The has method returns true if messages exist for the given $key, and returns false if no messages exist.

The following examples demonstrate the usage of the has method:

 1<?php

 2

 3use Illuminate\Support\MessageBag;

 4

 5// Create a new MessageBag instance.

 6$messageBag = new MessageBag;

 7

 8// false

 9$hasMessage = $messageBag->has('test');

10

11// Add the message to the message bag.

12$messageBag->add('test', 'Example message');

13

14// true

15$hasMessage = $messageBag->has('test');
