you have submit form either using button or submit form on change of qty.

onchange="this.form.submit()"

<form action='' method="post">     <select class="form-control" id='qty' name='qty' onchange="this.form.submit()">          <option value='1'>1</option>          <option value='2'>2</option>          <option value='3'>3</option>     </select> </form>  <?php     if (isset($_post['qty'])){         $qty = $_post['qty'];         echo $qty;     }  ?>

if javascript disabled above code not work in case had use submit button

<form action='' method="post">     <select class="form-control" id='qty' name='qty'>          <option value='1'>1</option>          <option value='2'>2</option>          <option value='3'>3</option>     </select>     <input type="submit" name="submit" value="submit"> </form>  <?php     if (isset($_post['qty'])){         $qty = $_post['qty'];         echo $qty;     }  ?>
