Refresh

Renzo

How can i prevent that the info is gatherd form the cache in stead of from my database..
Often I have to hit refresh to see the new info in the database (most annoying for the layout i defined and often change)

Turn your browser's cache off. If you are behind a caching proxy or something similar, you can use a pragma: no-cache header. Sometimes it will work.

Yes, but i can't do that for the visitor on my site..
I want to know a way so that the visitor sees always the up to date info/layout without clicking the refresh button
Tnx anyway.

There's probably some other method, but I always just put the ? on the end of the php filename and that makes it refresh every time. Say your PHP script is called script.php. If you access it directly as script.php it will sometimes not refresh, but if you access it as script.php? it always will 🙂

The problem is simple if u r accessing the page and dont get the refreshed data then the problem lies in the browser

try changing the setting of the browser to visit the page for every request

Sadly, most people who use the internet have their browsers set to cache stuff. Use the ? method I described above.

I use a double method:

First, at the top of your script do this:

header("Cache-Control: no-cache, must-revalidate");

header("Pragma: no-cache");

Then I make

$refresher=uniqid("");
echo "<a href=\"http://".$_SERVER["SERVER_NAME"]."/path/document.php?rfr=".$refresher."\">Some link</a>";

It does all the work I need...
