PHP不会更新以显示新的SQL内容

Question

When i update some text on my site and put it into the mySQL DB... the site refreshes but does not update the content to the new content in the Database, and i cannot figure out why, i have removed all cache etc...

Example, i have the page say "Lorem ipsum", and update that with my form to say "Hello there".. the page refreshes but does not change the "Lorem ipsum" before i do a force refresh.. (shift + refresh), and i have removed all cache both in my php documents but also in my .htaccess

my php documents cache removal

<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" />
<meta http-equiv="cache-control" content="max-age=0" />
<meta http-equiv="expires" content="0" />
<meta http-equiv="expires" content="Tue, 01 Jan 1980 1:00:00 GMT" />
<meta http-equiv="pragma" content="no-cache" />

Heres the retrival

$select = mysql_query("SELECT * FROM `Filling` WHERE `group` = '$page'")or die(mysql_error());
    $row = mysql_fetch_assoc($select);
    echo "$row[text]";
    ?>

Code for going back:

var back = document.referrer;
window.location.replace(back);

basicly, with somethings cutoff... I just cannot figure out how to get this to update properly, thanks in advance :)

Answer 1

Try print_r($row); or var_dump($row); to see if there is anything in it.

if text is a key in $row then use $row['text']

Answer 2

If you're using JavaScript to redirect back to the previous page using something like

history.go(-1);

or

history.back();

Then you are going back in the browser history, which will NOT reload your page's content. Instead, you should use:

window.location='[your page URL here]';

Or you could just post back to the same page and do your processing at the top of the script.

Answer 3

I ended up making a querystring with "&time=".time(); which forces the browser to update because it is a new URL... Thanks for all your suggestions though :)
