you should never data change in request. said in html 4 , http specifications

if processing of form idempotent (i.e. has no lasting observable effect on state of world), form method should get. many database searches have no visible side-effects , make ideal applications of query forms.

if service associated processing of form has side effects (for example, modification of database or subscription service), method should post.

for example, happens if user has "web accelerator" pre loads urls on page ?

you should check request indeed come user on website, or open door easy csrf vulnerability.

with said, usual method fix want that, after updating user status in database, should issue redirect non-modifying page.

base page -> click on change link -> change status in database , redirect base page again

<?php if(($age== '') || ($location= '') || ($status= '')) {    mysqli_query(/* update whatever */);    header('location: myaccount.php');    exit; } 

if refresh page, on base page won't change anything. if press "back" in browser, goes page base (pages issues redirect aren't saved in browser history).
