Reload problem???

jsalbert

Hi,

I have 2 php scripts. Both have to query from Mysql. One is only output as values in columns, the other is using GD_Lib to print some curve for clients.

Because the data are updated in realtime. I wrote "auto reload" code by using java script as:

to both of them to act a refresh per 15 second

the 1st one (show values in columns) runs well, but the other is strange. Everytime when it execute reload(). It appears a message box with OK & cacel button. Does there anyone know what the problem is???

thank you!!

regards,
albert

This is HTML it might work better... i guess lol
<META HTTP-EQUIV=Refresh CONTENT="3 ; URL=test.php ">

3 -- The wait time tell it refreshs again

test.php -- The place it refreshs to... leave it blank and it will go to the page it is on right now... i think 🙂

I've tried the code which you suggestted. Since my page is post from previous page with some variables.
If I use the code you suggestted, it won't show the correct info. it is due to the $_POST variable issue.
The answer I want to know is why the defference response from the same codes. Is it just due to GD_Lib or receiving external variable ??

Or the same effect may be achieved using http-header like this:

header('Refresh: 3; url=test.php');

It's completely the same, but you needn't put that line in html.

ahh yes i had forgoten bout that.. thats cool, i had been using the HTML version which was annoying lol

and, if i understood the question, this is how you would do it.
test.php

if(!($data = $_GET["data"])
{
$data = "hello";
}

header('Refresh: 3; url=test.php?data=$data);

thats how you would send and recieve variables

As I understood, the main problem was to get rid of variables?..
