Question

I have this script.

<script type='text/javascript' charset='utf-8'>
    $(window).load(function(){
        window.loadIframe = function(frame) {
           var link = $(frame).attr('src');
           $.post('link.php', {'link': link}, function (txt) {});
        }
    });
</script>

If I replace $.post('a.php', {'link': link}, function (txt) {}); for alert(link) it will display a link: example(http://www.example.com/123-a-b-c-d-e-f-0), ok.

Then, in the link.php I have this code:

<? 
...
$link = filter_input(INPUT_POST, 'link', FILTER_SANITIZE_NUMBER_INT); 
    mysql_query("insert into prueba values ('', '$link')"); 
...
?>

When I check the database, the value inserted isn’t the full link, is 123——-0

Where is the problem? Thank you very much.

Answer 1

It’s because you’re using FILTER_SANITIZE_NUMBER_INT. From the docs:

Remove all characters except digits, plus and minus sign.
