Request Forwarding

[Gez]

Hi,

How do I forward a request to another php page?

In JSP, I would use a request dispatcher, which keeps all session data and request parameters intact. What's the php equivalent?

Many thanks.

Look at the [man]header()[/man] function.

Yup, you can go something like
header("Location: http://www.yoursite.com/yourpage.html");

Unfortunately, locations have to be given in full like that, but if you dont want to specify the domain name and just have it work relative to the current script, use this:

header("Location: [url]http://[/url]".$SERVER['HTTP_HOST'].dirname($SERVER['SCRIPT_NAME'])."/yourpage.html");

That would go to the page "yourpage.html" in the same directory as the current script 🙂

This doesn't seem to be keeping hold of my request parameters...?

I have a number of parameters which I want to forward on, am I doing something wrong?

Actually Rohan, you can do something like the following:

header("Location:newpage.php");

and it will work ok. You dont have to specify the hostname or anything like that.

This works if I include my parameters as GET, such as:

header("Location:newpage.php?myVar=value");

...but what about POST requests? The values seems to get lost somewhere, how can I retain them?

If you want to pass things on using the POST method, then you'll have to use a form, perhaps using hidden inputs. The only problem with this is that anyone can view the HTML that has been passed to the browser and change the settings.

What I do is to use numbers instead of a characters, so if I want to go to a members profile page, for example, I do:

header("Location:profile.php:?id=123");

where id is the variable name and the page looks up the profile for member number 123.

Hope this helps in some way...
