Header Variables

biscutty

I am using the header function to direct my script to another page bu i need to retain my variables..

Is there a way to pass all variables in a script with the header function?
and if so how?

thanks

Are the variables already in the query string? If so, you can use one of the $_SERVER[] variables. I don't recall which one, but it's obvious if you look at the list.

Then you can just add that onto the url when you do location.

header("Location:page.php" . $_SERVER['something']);

[font=arial]What I think Pig is trying to say, is to use a query string to pull the previous page's data. Example, say you have gotten the form value, $_POST["name"]; from the previous page, and you want to now redirect them to a different page. Well, you can use the header function like this to send as a query string:[/font]

header("Location: yourpage.php?name=".$_POST["name"]);

[font=arial]Of course, you'd retreive the values on the yourpage.php file with $_GET["name"].
You could also try using a hidden form with its values populated by PHP from the previous page, to send to the next page. But that's only if you want the page to completely load before redirection.[/font]

you can't do it with hidden fields and post the vars with hidden fields in a simple redirect, you need to look into www.php.net/curl for that method

it is just easier to send them via the query string

[font=arial]Like I said, but that's only if you want the page to completely load before going onto the next "step" in the form process. Example, you could populate hidden form fields' values with the previous page's form submitted values, and do this through multiple pages--for multi-page processing.
But yes, a query string is the best way to go about it, unless it's very large amounts of data.[/font]

hence, no redirection, but yes it would work that way, and yes get has character number limits
