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; } ?>
