PHP and mod rewrite

[Skitty]

I've been working on this php script based off of tinyib to work just like 4chan, yeah.. you heard right.

I came to a problem when I noticed how 4chan interprets page requests as so~

<a href="1">1</a>

Now the above is obviously a request for the second page on almost any board at the place and when you click it, the url changes from ~

http://boards.4chan.org/g/

to the url

http://boards.4chan.org/g/1

And if you add a trailing backslash to the url as so~

http://boards.4chan.org/g/1/

you will get an error which should mean the request is not a directory but an argument sent over the url like the typical forum values you see like ~

forum.net/forum.php?Page=1

Some one told me that moot uses mod_rewrite to interpret the request, I couldn't get the said module to work under uniserver for some reason, even though "server-info" screams at me that the module is loaded and ready to go, but when I add a rule, it gives me a server error or apache fails to run when restarted.

I'm basically very close to replicating 4chans script. but I cannot figure out how to interpret the url in my script so I can deliver the right page.

Heres how 4chan uses the page ref ~

<a href="1">1</a>

Very simple looking but I don't know how to catch this and not get a 404 error because of the "1" which apache thinks is a directory.

Did you turn the rewrite engine on? It's not very helpful when you don't show how you are using mod_rewrite nor is it helpful when you don't give an exact error.

Virtual Host

<VirtualHost *:80 >
RewriteEngine On
RewriteOptions Inherit
  ServerName boards.phpchan.tk
  DocumentRoot C:/UniServer/www/chan
</VirtualHost>

Testing rewrite conditions I've used and do not work in neither .htaccess or httpd.conf

DirectoryIndex index.html
addtype application/x-httpd-php .php .html
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php

the errors I get are usually 404's and 401's, I believe I was getting a 404 due to a bad alias condition I had in httpd.conf, as for the 401's, I do not have anything blocked so I can't see why I was getting that.

On a side note, I even tested this with

RewriteBase   /test
RewriteRule   ^index\.html$  1

just to see if it was working, obviously nothing is working with mod rewrites or I am failing to understand how to do this properly, I've already almost religiously followed every tutorial I've encountered on the web and still can't get this right.

This was placed inside a VirtualHost section:

RewriteEngine On
RewriteRule ^/index\.shtml /test2.html
RewriteRule ^/$ /test2.html

It replaced both http://domain/ and http://domain/index.shtml with http://domain/test2.html. I imagine what you need is:

RewriteEngine On
RewriteRule ^/g/$ /g/1

[Skitty]

Thanks, I noticed the message was actually saying there was an internal error, the error info I gave earlier was incorrect, at the last minute, I actually noticed what was going on.

lol, silly me.

So I checked in the apache error log and found this nifty message that was logged more than a few thousand times and started getting logged around the same time I started trying this (yesterday), the massage ~

[error] [client 70.124.221.65] Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden: C:/UniServer/www/test.php

So I threw this into .htaccess

<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine On
RewriteRule ^b$ test.php [L]
</IfModule>

And viola, moral of story; if there are error log files, f***ing use them.

Thank you for the assistance Valik.

Edit: But the main point of this thread remains unsolved, how do I catch the "1" value in the php script when its requested in this manner?

Subsequent Edit: Never mined, I've think I got this.

"modrewrite"

<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine On
RewriteBase   /
RewriteRule ^test/(.*)$ test.php
</IfModule>

Example php usage

<?php
$T=explode('/',$_SERVER["REQUEST_URI"],3);
$X=$T{2};
$Y = $X + 1;
echo'<a href="'.$Y.'">'.$Y.'</a>'
?>

the above was a crude way of doing it.

The below is what I needed.

RewriteRule ^([a-zA-Z0-9])/?$ test.php?board=$1&page=$2
RewriteRule ^([a-zA-Z0-9])/([0-9])/?$ test.php?board=$1&page=$2
RewriteRule ^([a-zA-Z0-9])/([0-1][0-5])/?$ test.php?board=$1&page=$2
 
RewriteRule ^([a-zA-Z0-9][a-zA-Z0-9])/?$ test.php?board=$1&page=$2
RewriteRule ^([a-zA-Z0-9][a-zA-Z0-9])/([0-9])/?$ test.php?board=$1&page=$2
RewriteRule ^([a-zA-Z0-9][a-zA-Z0-9])/([0-1][0-5])/?$ test.php?board=$1&page=$2
 
RewriteRule ^([a-zA-Z0-9][a-zA-Z0-9][a-zA-Z0-9])/?$ test.php?board=$1&page=$2
RewriteRule ^([a-zA-Z0-9][a-zA-Z0-9][a-zA-Z0-9])/([0-9])/?$ test.php?board=$1&page=$2
RewriteRule ^([a-zA-Z0-9][a-zA-Z0-9][a-zA-Z0-9])/([0-1][0-5])/?$ test.php?board=$1&page=$2
 
RewriteRule ^([a-zA-Z0-9][a-zA-Z0-9][a-zA-Z0-9][a-zA-Z0-9])/?$ test.php?board=$1&page=$2
RewriteRule ^([a-zA-Z0-9][a-zA-Z0-9][a-zA-Z0-9][a-zA-Z0-9])/([0-9])/?$ test.php?board=$1&page=$2
RewriteRule ^([a-zA-Z0-9][a-zA-Z0-9][a-zA-Z0-9][a-zA-Z0-9])/([0-1][0-5])/?$ test.php?board=$1&page=$2

<html>
   <head>
      <title>mod_rewrite test</title>
   </head>
   <body>
      <p>
         The requested board is:
         <?php echo $_GET['board']; ?>
      </p>
<p>
         The requested page is:
         <?php echo $_GET['page']; ?>
</p>
<?php $X=$_GET['page'];$Y = $X + 1;echo'<a href="'.$Y.'">'.$Y.'</a>' ?>
   </body>
</html>

Although, I am still having a problem figuring out a legitimate easy way to fix up the url in the users browser, lets say we were at "thisdomain.com" and we requested board "x", the url will look like "thisdomain.com/x".

How can I have the url be set as "thisdomain.com/x/", with the appended forward slash?

If you go to "boards.4chan.org/g" the url is set as "boards.4chan.org/g/", automatically appending the forward slash, the guy running that place sure used a whole boat load of mod rewrite tricks or something.

How would I go about adding that forward slash if its missing? I.e If you use the above example php and mod rewrite code and access the script w/o appending the slash mark and you click on the number link, the number is appended to the letter of the board requested, how do I stop that?

Edit: More specifically, I'm currently attempting to figure out how to append the trailing slash to the requested board, and if a board is requested along with the page number like so "domain.com/x/1/", give a 404, which shouldn't be to hard.

Edit #2: Obviously, I don't think mod rewrite is what I'm looking for in order to append the trailing slash on the client side, I guess I'll have to jumble up some php that echo's a meta refresh tag that fixes the url.

What you need to do is the following:

<IfModule mod_rewrite.c>
#Turn on the engine
RewriteEngine on
#Set the base
RewriteBase (Set your base here)
 
RewriteRule ^\/g\/([0-9]+)\/?$ forum\.php?Page=$1 [L]
#First group is searching for what page the user is on
#Second group is where this request will be directed to on the directory
#[L] stops any more rules from executing
</IfModule>

Hope this helps!

Sure did, thanks.

I can't believe I overlooked the [L] parameter, it was something I needed.

I also need to mention that It was my mistake saying this is based off of tinybb, when really it was tinyib...

[ProgAndy]

By the way, the parameter QSA is also useful. This allows to use GET-parameters in the URL, too. Example:

example.com/g/1?order=y

without QSA: example.com/forum.php?Page=1

with QSA: example.com/forum.php?order=y&Page=1

Edited October 15, 2011 by ProgAndy

[shanet]

Oh yes I completely overlooked QSA

Thanks ProgAndy

For the OP, QSA stands for Query String Append.

The flag could/should be changed to [QSA,L]

Glad to hear that it helped
