Laravel 4, how to test if a Checkbox is checked?

Question

I am trying to see if a checkbox is checked or not in my controller. I've read that this is the code to do it

if (Input::get('attending_lan', true))

But that returns true even if the checkbox is unchecked.

Answer 1

Use Input::has('attending_lan')

Generally speaking, if the checkbox is checked, the request variable will exist. If that is not the case you have a problem somewhere else in the code.

Also relavant: Does <input type="checkbox" /> only post data if it's checked?

Answer 2

Assuming you have this form code in your view:

// view.blade.php
{{ Form::open() }}
    {{ Form::checkbox('attending_lan', 'yes') }}
    {{ Form::submit('Send') }}
{{ Form::close() }}

You can get the value of the checkbox like this:

if (Input::get('attending_lan') === 'yes') {
    // checked
} else {
    // unchecked
}

The key here is that you have to set a value when creating the checkbox in your view (in the example, value would be yes), and then check for that value in your controller.
