The Form::hidden() method works exactly the same as the Form::input() method except that it automatically sets the type attribute to hidden.
echo Form::hidden('name');
<input type="hidden" name="name" />
Add the second parameter to declare a value
echo Form::hidden('name', 'value');
<input type="hidden" name="name" value="value" />
The third parameter accepts an array of attributes
echo Form::hidden('name', 'value', array('id'=>'name'));
<input type="hidden" name="name" value="value" id="name" />
