Thread: Refreshing php page every 5 secs WHILE SAVING INFORMATION
Hi
I have a php page that I need to be rereshed every 5 seconds to make sure
that the information displayed is up to date. I tried the Refresh Meta
tag :
<META HTTP-EQUIV="Refresh" CONTENT=5>
which worked OK (in Explorer, not in Netscape?? but thats another issue!)
BUT it doesn't work properly to my needs. You see suppose the page that I
want refreshed is called bidForHouse.php, well bid.php contains a <FORM>
which passes in a variable $id to bidForHouse.php, it works grand the
first time it loads up, i.e. it has obtained what the value of $id is and
can act accordingly but when the refresh comes into operation it is like
the value of $id got lost and is set to null, thats my problem!
Any ideas on how to save the value of $id before refreshing?
Thanks a million, I hope one day that I might be able to contribute to
this page but I can't see it happening for at least a few years, I have a
long way to go!

Pass it on the command line. Take this part of the above refresh line: URL=index.php and make it URL=index.php?$id And look for $argv[0] at the top of the script.

I'd think you'd need to do something with Sessions to keep track of that value. So that way when the page reloads, it just pulls the value out of the appropriate session variable.
