htaccess custom 404 error help

passing vars to custom 404 page

[indiandomain]

need a little php help.
i want any html document on my server to goto a 404 page which takes it to /s.php3?term=

for eg mydomain.com/loans.html would show mydomain.com/s.php3?term=loans
how do i pass the variable 'term' in the .htaccess.

anyone can add a few php codes to pass the term variable.

ErrorDocument 404 /s.php3?term=

<?php
$uri = $_SERVER['REQUEST_URI'];
$uri = urldecode($uri);
$uri = preg_replace("/ +/"," ",$uri);
$uri = trim($uri);
$uri = preg_replace("/^\/¦\/$¦\.(htm[l]?)/","",$uri);
header("Location: /s.php3?term=$uri");
?>

[DrDoc]

Note that this example doesn't take into account subdirectories or existing query strings...

/loans.html
/loans.htm
/loans/
/loans
...would all redirect to /s.php3?term=loans

However,
/loans.html?
/loans?
...would redirect to /s.php3?term=loans.html? and /s.php3?term=loans? respectively.

Let us know if you need any additional matching...

[DrDoc]

Actually, if you change this line:
$uri = preg_replace("/^\/¦\/$¦\.(htm[l]?)/","",$uri);

to this:

$uri = preg_replace("/^\/¦[^a-zA-Z0-9].*/","",$uri);

Then it will strip the first non-alphanumeric character, and all following characters.

So,
/loans
/loans.html
/loans/
/loans.lkajshd ,.asdfkl;aj sdjas.fjk
...will all redirect to /s.php3?term=loans :)





Note: The pipe ¦ should not be broken, so you need to replace them manually

[indiandomain]

can you please check if this syntax is correct.

will my .htaccess look like this

ErrorDocument 404 <?php
$uri = $_SERVER['REQUEST_URI'];
$uri = urldecode($uri);
$uri = preg_replace("/ +/"," ",$uri);
$uri = trim($uri);
$uri = preg_replace("/^\/¦\/$¦\.(htm[l]?)/","",$uri);
header("Location: /s.php3?term=$uri");
?>

DirectoryIndex index.php3
<Limit GET>
order allow,deny
allow from all
</Limit>

[DrDoc]

Well, in your .htaccess you should just refer to an error handling page.

ErrorDocument 404 /404.php3

Then, put that PHP code in a file you name 404.php3. That's the best and easiest way :)

[DrDoc]

If you want, you can even do this:

ErrorDocument 404 /s.php3

... and put this code first in your s.php3 file:

<?php
$uri = $_SERVER['REQUEST_URI'];
$uri = urldecode($uri);
$uri = preg_replace("/ +/"," ",$uri);
$uri = trim($uri);
$uri = preg_replace("/^\/¦[^a-zA-Z0-9].*/","",$uri);
$term = $uri;
?>

However, this could cause problems if your s.php3 file is ever accessed directly. If it only handles error requests, then it should be ok.

dr one problem
im using this in 404.php3
<?php
$uri = $_SERVER['REQUEST_URI'];
$uri = urldecode($uri);
$uri = preg_replace("/ +/"," ",$uri);
$uri = trim($uri);
$uri = preg_replace("/^\/¦[^a-zA-Z0-9].*/","",$uri);
header("Location: /s.php3?term=$uri");
?>

site.com/loans.html goes to site.com/s.php3?term=/loans.html

instead of going /s.php3?term=loans

something wrong in the php code?

[DrDoc]

Hmmm..

Try replacing:
$uri = preg_replace("/^\/¦[^a-zA-Z0-9].*/","",$uri);

with:

$uri = preg_replace("/^\//","",$uri);
$uri = preg_replace("/[^a-zA-Z0-9].*$/","",$uri);

[indiandomain]

man this is killer.
it works
:-)

1 more things doc.

in the browsers address bar i get /s.php?term=loans instead of /loans.html

any solution for this

[DrDoc]

Yes, in your error document, change:

header("Location: /s.php3?term=$uri");

to:

$term = $uri;
include("/absolute/path/to/file/s.php3");

[indiandomain]

doc thanks a million.
it worked.
:-)
now something like free_loans.html opens on /s.php3?term=free
how do i make it open at /s.php3?term=free+loans

[DrDoc]

Replace:

$uri = preg_replace("/[^a-zA-Z0-9].*$/","",$uri);

with:

$uri = preg_replace("/[^a-zA-Z0-9_].*$/","",$uri);
$uri = preg_replace("/_/","+",$uri);

Note that you don't need to pass the _ as a plus. You can replace the + in the above function with just a space. The variable would then be "free loans" instead of "free+loans". No urldecoding will be performed in s.php3 since the file is included

[indiandomain]
