[development] authentication hooks - PLEASE HELP

[Sheryl (Permutations Software)]

Ugh. I'm still getting the error message:

warning: Cannot modify header information - headers already sent

Honestly... This is so frustrating. I think it would take less time to write
my own CMS. How come there is not support?

Putting output buffer statements into my theme seems to have solved the
tracing problem, at least. At the top and bottom of the hook_page() function
in my PHP theme, I added these statements:

	$output = eval('ob_start();');
	...
	$output .= eval('ob_end_flush();');

I still have many other problems, however. Drupal calls databases and
functions at unpredictable times. I can't tell what's going on and there is
no documentation.

The only way I know to turn on output buffering it to create the buffer at
the top of the page and write it at the bottom with these calls:

ob_start();
...
ob_end_flush();

But with Drupal - who knows where the top of the page is, or the bottom.
Hmmm... Actually, I wrote a custom template in PHP (no engine). Maybe I can
put it in my template file.

Thanks for the watchdog tip... I don't know where common.inc is used or when
it would "be available". I'm a strong PHP programmer, but not very familiar
with Drupal's architecture.

I did write to the author of the Webserver Auth mod and he wrote back -
hopefully he can help.

Hi Sheryl,

      I believe that output buffering is a PHP option - you can  
enable it in your
php.ini file, or .htaccess, or in your settings.php file.

      An alternative hack is to write debugging output to the  
watchdog table
(works only for debugging sections of code where common.inc is  
available):

     watchdog('debug', "var = $var");

It's ugly but hey, what people will do in times of desperation...

I've not looked at Webserver authentication.  Have you tried  
contacting the
maintainer?  You might also try hanging out in #drupal at  
irc.freenode.net.

Have a look at drupaldocs.org for the developer documentation, including
overviews of the hook system.   The Drupal handbooks may also be of
help, especially the Developer handbook (http://drupal.org/handbooks)

Cheers, Djun
