I was trying to update my product status. Suppose if the product has stored as feature_product then it will appear in view. Now if i uncheck the input box it should return 0 but it always return 1. How to i set value of input box as 0 if it's uncheck?

@if($product->feature_product == 1)
        <fieldset>
            <div class="form-group">
                <label class="col-sm-3 control-label "></label>
                    <div class="col-sm-9">

                        <label style=" padding-top: 0;" class="checkbox">
                            <span class="icons"><span class="first-icon fa fa-square-o"></span><span class="second-icon fa fa-check-square-o"></span></span> 

                            <input type="checkbox" checked name="feature_product"  data-toggle="checkbox"> Feature Product       
                        </label>            
                    </div>
            </div>
        </fieldset>
    @endif

Controller part for getting the value:

$product->feature_product = Input::get('feature_product')?: 0;
