i using bootstrap datepicker allow user select date input date. 1 thing wondering, when user not select date datepicker. not show null value in database, show date format 0000-00-00.

here html:

<div class="form-group">  <label class="control-label col-sm-3">date of birth</label>    <div data-date-viewmode="years" data-initialize="datepicker" data-value="null" data-date-format="dd/mm/yyyy" data-date="{{date('y-m-d')}}" class="input-append date dpyears col-md-8">      <input type="text" name="birth_date" placeholder="{{date('y-m-d')}}" size="16" class="form-control">      <span class="add-on birhtdatedatepicker">        <button class="btn btn-primary" type="button"><i class="fa fa-calendar"></i></button>      </span>    </div>  </div> 

here js

$('.dpyears').datepicker({     format: 'yyyy-mm-dd',     autoclose: true,     setdate: new date() }); 

here insert code:

public function postclient(){ $input = request::except('_token','photo','signature'); return $input;     if (!empty($input) && is_array($input)) {         $addnew = new client();       foreach ($input $key => $value) {         $addnew->$key = $value;       }     } }
