Opening a new php page?

NuTz

Hi all,

First off thansk for the site 🙂 Saved me hours and has been very very usefull.

Quick question:

I have an if else statment and what i want it to do is as follows:

IF then display a form and check for errors redisplaying itself if there are any (this all works fine).

ELSE open up a page called updatedb.php that needs the variables from this page and the previous page passed to it (theres a lot of variables).

I cant even find the command to open a web page any help?

Normally the form action statement would open the next php page but in my code it opens itself as it needs to rerun if there are errors.

Cheers

Huh? I couldn't understand that... Do you mean redirect or open a new window? And what do you mean "that needs the variables from that page and previous page passed to it"?
Do you mean the update page needs variables from the page this php script is on, and the previous page? Then you can shove all the variables into sessions.

Sorry on rereading its not very clear...ill try again...

page 1 - is a form that collects data and passes it to page 2 using <form action = page2.php>. e.t.c. Basic stuff

page 2 - again uses a form to collect data. However this form uses <form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post">. It needs to do this so it reruns if there is an error.

I have an if else statement running to control all this and the form is a function. So it works like this:

display page
is there an error?
yes then call function (redisplays page)
is there an error?
no then i want it to open a new php page in the same window but pass variables collected in page 1 and page 2 to it. I've tried using include "page3.php"; but none of the variables from page 1 are passed to page 3.

Hope thats clearer?

Well for the changing page, unless the user clicks a link, you'll hav to redirect them.

You can redirect with some php header thingy (I never use that - I redirect another way because if you do that, you can't have output anything with echo or stuff...) or you can use html meta tags:

Page 3 will get page 2's form vars like normal through the post super global, but to get page 1's you'll have to use sessions.

At the beginning of all pages using sessions (page 2 and page 3) you must do:

session_start();

Then if register_globals are on (if you have to use $_POST['var'] to use variables from a form, globals are off), then you ALSO have to use session_register['var'];...

Then you'll have to copy the vars across...

$SESSION['firstname'] = $POST['firstname'];
Only copy the vars from page 1(obviously). 🙂

Sessions create temp files on the server that get deleted when the browser is shut. These files contain the session variables. 🙂

So on page 3 you can use page 2's vars with $POST['page2var'] and page 1's vars with $SESSION['page1var']

I hope that made sense. 🙂

It did make sense ill give it a go.
