.htaccess vraagje

ErrorDocument 404 /missing.php

<?
echo "You wanted to visit: " . $_SERVER['REDIRECT_URL'] . "<br />";
echo "This also works: " . $_SERVER['REQUEST_URI'];
?>

<? print_r($_SERVER): ?>

Punt is, als ik in die PHP-file het foutieve adres wil opvragen krijg ik het adres van de 404-pagina terug, ik moet het adres dus hebben van voor de redirect. Voor je je afvraagt of dit echt niet naar php wordt doorgestuurd: nee, ik heb de volledige $_SERVER array uitgeprint en phpinfo() en daar staat niets van het orginele adres in.
Omdat ik deze pagina generiek wil maken zodat ik hem de volgende keer kan gebruiken wil ik het toch graag oplossen in plaats van het weglaten. Dus wil ik het adres meesturen vanuit de .htaccess file, iets in de vorm van:

ErrorDocument 404 /test/errors/404.php?url={SCRIPT_URI}

{SCRIPT_URI} heb ik daar neergezet om aan te geven dat het om die variabele gaat, die heb ik inmiddels gevonden, punt is dat hij die niet meestuurt en ik heb de afgelopen 3 uur nergens kunnen vinden hoe dat wel zou moeten. Vriend van me zegt dat ik kan proberen om $1 mee te sturen, dat zou de eerste meegegeven variabele zijn. Als ik dat doe krijg ik die ongeparsed weer terug (hij komt PHP dus letterlijk als "$1" binnen).

dus via PHP superglobals gaat het zeker weten niet lukken

Dear all,

First of all, sorry if this question was already answered... i didn´t found it!
Well, i´m using Apache 1.3 and its ErrorDocument for my website. I´m using php too, and the problem is that after redirected to an error page, let´s say 404, i lost globals data like HTTP_REFERER, or even QUERY_STRING and REQUEST_URI.

It´s not that important, anyway i would like to show in the 404 page the Url that the visitor was looking for, before the redirection.

Well, i´m almost sure it´s an Apache issue and not php.

Another question... sorry!
Why Apache don´t automatically send an HTTP status, e.g.: 404, when redirecting to a page!?
Is that normal !? Or... is any way to make it possible!?

Thank you

In PHP

HTTP_REFERER wont be set since it was redirected
QUERY_STRING is only for current page
REQUEST_URI is only for current page

You can try putting this in your apache http.conf file or a .htaccess file.
----------------------

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ http://www.mysite.com/404.php?url=$1 [L]

-----------------------
Will check the requested file if it exists. If it doesnt then it wil reidrect to your page appending the requested file as a variable $_GET variable.


Regards.
Nick

Hi Nick, thanks for your reply!

The error thing is working fine. I´ve made same changes for my needs. It´s now redirecting to the error page and showing the searched file/url and keeps it in the address bar.

Here is what i have:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^/(.*)$ site/error/404.php?url=$1 [L]

'site' is my website folder, i don´t have it in the root, so i always need to specify it.

The problem is that i´m using the 'DirectoryIndex' and other 'rewrites' and if i don´t specify the directory´s default page in the url it goes to the error page. The same to other 'rewrites'... they fail!
Don´t know if it matters, but i´m using: Options ExecCGI FollowSymLinks Includes MultiViews, so the rewrites can work!

Any idea!?

Sincerely,
Gesf

Could you paste your other rewrites and settings here? Thanks!

Of course! Here goes:

RemoveHandler .html .htm .xhtml
AddType application/x-httpd-php .php .html .htm .xhtml
AddHandler cgi-script .cgi .pl
# This one fails if don´t specify the default page in the url.

DirectoryIndex site.php default.php

<FilesMatch "\.(ht|ini)$">
Order allow,deny
Deny from all
</FilesMatch>

Options ExecCGI FollowSymLinks Includes MultiViews
RewriteEngine On
RewriteBase /
# This one fails too... to the 404 error page!
RewriteRule ^/tutorials/(.*)/(.*).htm site/tutorials/?tutcat=$1&tutid=$2 [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^/(.*)$ site/error/404.php?url=$1 [L]

ErrorDocument 400 http://127.0.0.1/site/error/400.php
ErrorDocument 401 http://127.0.0.1/site/error/401.php
ErrorDocument 403 http://127.0.0.1/site/error/403.php
# ErrorDocument 404 http://127.0.0.1/site/error/404.php
... and so on with this. They are the last thing!

I was wrong! Is just the DirectoryIndex which isn´t working! The other rewrite fails:
"... tutorials/?tutcat ...". Because i´m not passing the default dir page!
But... i want to use it

Thanks in advance!

Another thing!
Using the the code you gave me, i can´t view .htm or .html files. Just .php... strange!
Thanks

stupid question: why do you redirect for error pages?
if apache just uses rewrite rules all server variables (like REFERER) should be available

Hey ahoffmann,
Yes, the referer is available, but (using ErrorDocument):
I request a page to the server and if it didn´t find it, it will redirect me to the error page. That´s when i loose the referer. Like CrYpTiC_MauleR said, in php, the referer won´t be set since it was redirected. So the idea is to catch the referer (before the error) and send it with the error page... as a variable. That´s what does that rewrite rule.

BTW CrYpTiC_MauleR: I try to find, but i couldn´t! What does " !-f " means?

Regards
Gesf

!-f
means: if file not exists, or is not a file

Thanks
Well, the rewrite is working, the only problem is that DirectoryIndex fails with it
