buffering to allow headers in code? [message #170163] Thu, 14 October 2010 13:39 Go to next message

I'm working through my class on PHP and I tried to put information from
my sign-on process in the navbar. This didn't work well, since I had to
reload the page to see it as the navbar was constructed earlier in the
code than the signon process. (Hard to explain, as we are building a
"dynamic" web page with lots of include files to fill in the main
content portion of the page.)

My instructor suggested that I do the reload of the page via php

header("Location: index.php");

after the sign-in. To do this, I have to turn on output buffering.

I recall struggling to turn off output buffering since someone here
recommended against it.

Any thoughts on this? Is this just a "quick and dirty" bypass for my
problem, accepted practice, a really bad idea, or customary practice?

I think I can code around this with some effort by putting a switch
statement in the header of the index.php, but that may be clumsy as
parts of the same web page will then be processed in two different areas.

What to do?

Thanks for any advice.

Actually, I read that wrong - sorry.

If your code is constructed properly, the header command will be sent
before any output - and no problem. If you buffer your output then send
the header command, the output won't get to the screen, anyway. So
there's no point.

Wow, (or as we used to say: yes, well, no fine).

I guess that qualifies under the "any" part of "any advice," but courses
(and instructors) are not that easy to come by. :) Besides, I've already
paid and I doubt I can get a refund. after 75% of the class has been
completed.

But I assume from your advice that it is a bad suggestion he made? Even
though PHP clearly allows for using output buffering and even rearranges
the output to put the headers first in the output buffer?

What data is not available when you assemble the navbar that you wish to
show in your navbar, and why is it not available?

This sounds like you have a sequencing issue, and may need to switch
round the order in which you are trying to do things. It should be
possible to assemble all the information needed to generate the webpage
before outputting any html.

At least partly I have to agree. If this is what your instructor told
you:

header("Location: index.php");

then he might be the wrong one for this job. The above violates the HTTP
RFC and can be considered a bug. It also violates conventions for good
URLs, because you should never link or redirect to index.* files.
Instead you use the directory - that's what these index files are for.

But for your problem - you should restructure your code. Put the login
routines first, then all the stuff that depends on it.

Yes.

OB has its uses, but not for fixing problems caused by an improper code
structure.

See it this way: Before your header() call, your code already has done a
lot of things, even built a navigation bar. And for what? For nothing.
Completely useless work. If you restructure your code, you don't need
this redirect anymore.

In short: Keep the business logic before any presentation logic.

This is an introductory PHP course.

We are creating a "dynamic" web page without AJAX (JavaScript) since
that will be in the intermediate course.

The site is a single file - index.php. Structured with a table (to avoid
learning CSS at the same time as PHP and SQL) for the header, footer and
three panes in between. The left-most pane is hte navigation, the center
is the Main and the right is the "news".

Each table cell has an include() for another file that makes up the
content of that cell. eg. include("nav.inc.php") for the navigation bar.

The main cell then has some conditional php code to decide on what
include to run, eg, one for "show summary of all recipes", or "show
details for a recipe", or "enter a new recipe/comment", etc. Also, of
course for registering and logging in.

Since I'm trying to display the name of the logged in user on the left
pane, that code is included before I run the code in the "main" cell,
hence my timing problem

THe class example sidesteps it by simply not putting the data in there.

Maybe I should just go back to the class example. Would be a lot less
headache.

Do you mind explaining this? If I understand you, if my site is

http://localhost/recipes/index.php

I should code:

header("location: /") ?

or

header("location: localhost/recipes/") ?

It doesn't make a lot of difference when you *process the data* - it's
when you *display the results* that counts. It would be quite easy to
do the processing before anything is sent to the browser, then display
the results in the appropriate place.

The index.php should never appear in any links or redirection URLs. The
better and recommended URL for the above would be

http://localhost/recipes/

Almost. But this still violates the HTTP spec, which _requires_ an
absolute URL for the Location header. So this would be correct:

header('Location: http://localhost/recipes/');

Of course this will be bound to your own local machine, which is not
good. To make it more flexible, replace the 'localhost' part with
$_SERVER['HTTP_HOST']. There are even more examples in the PHP manual.
Just see the page for the header() function for more details.

This is what was meant by "restructuring your code". You should really
perform any state operations (like 'login user x', 'delete page y',
etc) before you start building any output. Obviously, since you're
just starting out, it's not helpful to talk about MVC patterns (worth
a Google and some questions to your instructor, just to get your
money's worth :P), but try to think of the actual output as the final
step in the process. I.e., PHP gets the request, does all the
checking, redirection, database stuff, etc - before a single line of
output is sent to the buffer/browser.

in the meantime, sending a header redirect will work - just don't
forget to die() or exit() after the header call to stop further
(unnecessary) processing. It is a classic security blunder to assume
that code execution stops after the header is sent purely because the
browser goes on it's merry way.

Hope this helps,

Hamish

The page is generated. At the point that the page is generated, you are
either logged in, or not logged in.

If you are not logged in, then presumably an option to log in is
displayed, and then presumably the whole page is reprocessed from the start.

But, this time round, you can:

(a) invoke a session handler
(b) process the log in details before you do anything else
(c) store the log in state and username in a session variable

before processing the nav menu.

Now, if you did that first, when you get down to doing nav, you can test
the logged_in session variable, and if the user is logged_in, use the
username session variable in generating your navigation bar.

None of the above. You should not need to use the header() function at all:

<http://httpd.apache.org/docs/2.2/mod/mod_dir.html#directoryindex>

But if you use it, you need to do it as Michael suggested, using
$_SERVER['HTTP_HOST'] in the header field value, for the host name is needed
for an (absolute) URI of the form

http://host/path/

as required by HTTP ─ <http://www.w3.org/Protocols/rfc2616/rfc2616-
sec14.html> ─ and you don't want to hard-code it.

This is not at all clear to me. You refer me to an Apache page, where I
cannot programatically code stuff. More specifically, mod.dir is to
define what happens if i send in a URL without a file and extension.

How does this help me if I'm in the midle of a PHP program and I decide
I need to reload the page?

First of all, "Pointed Ears" is a troll with no idea what he's talking
about. Just check this and other newsgroups.

header() is a perfectly good function to use where necessary. One of
the things it can do is tell the browser to redirect to a new page. But
what Micha is saying is correct - use an absolute URI when redirecting,
i.e. including the domain.

For instance, header('Location:http://www.example.com/recipes'); would
be correct. header('Location:/recipes') would not.

Sure, most browsers today would accept the latter and redirect
accordingly; however, that is not according to the RFC's and is just
something many (not necessarily all) browsers currently do. The former
will work with ALL RFC-compliant browsers.

But as you've noted, this cannot be done after *any* output (even white
space) has been sent to the browser - that is a limitation of the HTTP
protocol, not PHP. The solution is to restructure your code such that
it makes the decision as to whether to redirect (or any other header()
call) is performed before any output to the browser.

OK, I can see how to construct that URL (or is it s URI?) from the
variables I have. This is all fine and dandy if I want to redirect to
the root page for a website, but what if I want to redirect to something
other than the index.php (or index.html) page that sits at the top of
the website? Or are you saying that all redirect must always redirect
to the top page of a website?

I'm sorry if I'm obtuse. I'm not trying to be, I'm just unfamiliar with
what is "right."

And then I get distracted by pointy ears and spend a lot of time on
stuff that does not help. :(

A Location header should provide an absolute URI - and that can
include specific resources (e.g. http://www.example.com/page-1.html).

Michael's objection to using index.php in the URI is purely stylistic.

Not sure what Pointy Ears was going on about not needing the header
function.

So, to answer your question: no it does not have to point to the root
page - just any *absolute* URI.

I have referred you to the Apache documentation telling you how to define
index.php as the "directory index" so that it is not necessary to write

Yes. And?

You appear to be a bit confused, and your use-case is not at all clear to
me. For reloading a document (there really are no "pages" on the Web) you
would choose *client-side* means, of course.

RTFM. The DirectoryIndex directive value is being inherited from parent
directories (or the server configuration) and can be overwritten (if the
required privileges are provided).

BTW, none of this has anything to do with PHP besides using the header()
function.

Certainly not.

For someone trying to not be obtuse, you are rather quick at jumping to
conclusions and pointing fingers at people when the problem is with *you*
(either failing to explain your use-case or understanding the suggested
solutions). Please change your attitude or go away.

Your own comment gives you away, PE:

Stop getting your jollies out of setting people up so you can knock
them back down with your Flame button (you know, below to "Function
RTFM", next to "Page RFC" on your keyboard of faux-helpfulness).

Hamish, if you look back through this and other newsgroups, that's about
all "Pointed Ears" is good for.

Maybe a better nickname than "Pointed Ears" would be "Pin Head". It
would be much more appropriate.
