[Resolved] Redirecting Browser!

jlpierce

Hi all,
I know I have seen this before, I can't find it now. How do I redirect the browser to a different page based on the result of a conditional test.

ie: if ($a = this) {go to the page};

you need to send an http header:

header("Location: http://www.yourpage.com/directory/file.php");

oh, also, you will want to use the exit function after that to make sure that the rest of the code on the page isn't executed. Unless you want that.

Hi Jason,

I tried the header(Location), but I get an error stating that the headers have already been sent.

I developing a login page and using PHP_SELF as the action of the form, if the username entered is found, the password matches, and the account is active I want to redirect them to a member page. If the they entered the info corrcectly but are not a user I want to redirect them to a new user page. If they just entered info incorrectly I want to redisplay the form with a message stating so.

Is there any other way to load a page with using the header function?

Any assistance is greatly appreciated.

TIA

the reason you are getting headers already sent is because you have text that is sent to the HTML page before the header function. If you make sure that the header function comes before any character that would be included in the HTML (including any whitespace preceding your initial <?php bracket) then you will not get that error.

Ok Jason,

let me clarify, my page "login.php" loads in the browser and displays a form for the user to enter their username and password, when the form is submitted the action is PHP_SELF upon return to login.php the variables username and password are put through several tests, if the user is verified I want to send them to a members area, if the account is inactive I want to send them to someplace else, and if the username or password is incorrect I want to give them a chance to re-validate themselves.

So for instance the username is found, passwords match, and the account is active I want to be able to say goto this URL.

Is this something that is not possible the way I'm approaching it, should I move my routines to function and include them.

I am just not sure.

TIA for you assistance.

John -
What appears to be the problem is that (and I'm sorry if I get this wrong because I'm just quickly glancing at it) is that you're attempting to resubmit the information to the same page and then attempting a redirect based on condition defined("x").

I ran imto a similar problem when attempting to do something very similar with ASP a few years ago, and the problem has to do with the HTTP headers and how they work. Hence, it won't help moving functions, includes, rewriting the URL, etc. Basically, the server already has information requested and because you have already requested a page, redirecting will fail. That wasn't very clear at all I know, I'm not clear on the details of that anymore but suffice it to say, you're attempting to append information where information already exists.

Most effective solution I've found ... redo your login paradigm. Instead of having it (the form) action submit to self (PHP_SELF) have it submit to a page that strictly handles those conditions and then handles them accordingly and passing the data along with the new page request.

So the short answer ... as far as I'm aware of because I never bothered to search for a work-around, rework. It's the simpliest solution I've come up with that has also allowed me to become flexible in handling that sort of stuff, and a work around in my opinion really wouldn't be worth the required effort.

Hope this helps!
