Pretty URLs

[manixless]

hello

i have the 9.0 version installed in my forum, but I can't unistall it because the package doesn't exist in the package folder. So, i neet it to upload again and then uninstalled. Can you attached the 9.0 version please?

thanks

What language files you have is completely irrelevant. What matters is what collation the database tables are. Can you confirm they are UTF-8 too?

On phpmyadmin, settings for the database is as follows ;

#  MySQL charset:  UTF-8 Unicode (utf8)
#  MySQL connection collation: utf_unicode_ci

As I said the problem is only for board links. not message links.

you can see the test site ;

www.mazda3clubtr.com

You'll need to check all the individual tables too.

However... seeing as only boards are effected, you could just change their board URLs. If you go the manage boards page you'll see that option for each board.

Just get it from the downloads page: http://code.google.com/p/prettyurls/downloads/list?can=1

Hi, I recently installed this mod and it functions perfectly, however it re-writes the URLs in notification emails but they no longer are delivered as clickable links, users have to copy and paste the link into their browser. Is this normal behaviour?

[Dannii]

Could you please forward an email like that to me?

[MazdaClubTR]

However... seeing as only boards are effected, you could just change their board URLs. If you go the manage boards page you'll see that option for each board.

I realised that there are similar problems in topics too. But hard to say what the reason is cause in some cases same characters are correctly converted and in some not

You can see a sample in below board

http://www.mazda3clubtr.com/teknik-genel-bilgiler/

first unsticky subject

almost all of the Turkish characters are badly converted while the topic below doesnt have any problem.

What should be checked in individual tables ? I have backed up my production site and restored it on to the test site where all the database charsets are the same.

[coyoteboy]

Certainly, though I can't get your email address on here, I can copy and paste the links into the "email user" page (just done it) but that's not the orignial source of the mail of course?

Hi Danni,

Is the pretty urls reverter compatible with smf 2 rc 1 ?

[MelfromBoD]

hi, can someone tell me where the pretty urls page is in the admin section? i cannot find it anywhere...

I solved this problem some time ago... you can search for it in this topic searching for my name maybe
I see it has not been solved yet...
Its a problem with the PHPSESION ID ... The url is not good make and some hostings has in its regular expresions rules that doesnt allow that URL. So they just show an error.

That link isn't working.
Well the database has an encoding/colation, but so does each individual table. The important ones would be boards and messages.

Hi Danni,

Is the pretty urls reverter compatible with smf 2 rc 1 ?

RC1 yes, RC1-1 yes but you'll need to emulate RC1. You could check on the mod page?

hi, can someone tell me where the pretty urls page is in the admin section? i cannot find it anywhere...

index.php?action=admin;area=pretty if it doesn't appear in your menu (probably because of language problems.)

No it's something else. The URLs are there and work fine, some silly email clients just won't turn them into links, the remain plain text.

[Mack450]

I just installed and it doesnt work. How do I make it work???

[Dannii]

How doesn't it work? Did you enable it yet?

[MelfromBoD]

"index.php?action=admin;area=pretty" this link doesnt work it only sent me back to the admin page. Any suggestions?

[Dannii]

Then your source files mustn't have been modified correctly. You'll probably have to do a manual install, the instructions are on the mod page.

[Mack450]

I enabled it but the links do not work

the old links do though.

vid to show
http://screencast.com/t/ffdZfSxa0

[Dannii]

Ahh a video is basically useless for giving me information. Can you show me the real pages?

[Mack450]

Well the forum url is

http://grizzlyriders.com/index.php?action=forum

and the menu and all that was changed to this link. but this link doesnt work...so i assume something didnt work right.

http://grizzlyriders.com/forum/

[Dannii]

Ahh perhaps try adding this to the top of your .htaccess:

RewriteBase /

[Mack450]

sweeeeeeeeeeeeeeeeeeeeeeeet! that did it! you rock man! thanks for the help!

[MelfromBoD]

I did the manual install now im getting this error:

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ')' in /home/undisputed/domains/blogodirectory.com/public_html/forum/Sources/QueryString.php on line 213

/*   This file does a lot of important stuff.  Mainly, this means it handles
      the query string, request variables, and session management.  It contains
   the following functions:

   void cleanRequest()
      - cleans the request variables (ENV, GET, POST, COOKIE, SERVER) and
        makes sure the query string was parsed correctly.
      - handles the URLs passed by the queryless URLs option.
      - makes sure, regardless of php.ini, everything has slashes.
      - sets up $board, $topic, and $scripturl and $_REQUEST['start'].
      - determines, or rather tries to determine, the client's IP.

   array addslashes__recursive(array var)
      - returns the var, as an array or string, with slashes.
      - importantly adds slashes to keys and values!
      - calls itself recursively if necessary.

   array htmlspecialchars__recursive(array var)
      - adds entities (&quot;, &lt;, &gt;) to the array or string var.
      - importantly, does not effect keys, only values.
      - calls itself recursively if necessary.

   array urldecode__recursive(array var)
      - takes off url encoding (%20, etc.) from the array or string var.
      - importantly, does it to keys too!
      - calls itself recursively if there are any sub arrays.

   array stripslashes__recursive(array var)
      - removes slashes, recursively, from the array or string var.
      - effects both keys and values of arrays.
      - calls itself recursively to handle arrays of arrays.

   array htmltrim__recursive(array var)
      - trims a string or an the var array using html characters as well.
      - does not effect keys, only values.
      - may call itself recursively if needed.

   array validate_unicode__recursive(array var)
      - makes sure a string only contains character which are allowed in
        XML/XHTML (not 0-8, 11, 12, and 14-31.)
      - tries to handle UTF-8 properly, and shouldn't negatively affect
        character sets like ISO-8859-1.
      - does not effect keys, only changes values.
      - may call itself recursively if necessary.

   string ob_sessrewrite(string buffer)
      - rewrites the URLs outputted to have the session ID, if the user
        is not accepting cookies and is using a standard web browser.
      - handles rewriting URLs for the queryless URLs option.
      - can be turned off entirely by setting $scripturl to an empty
        string, ''. (it wouldn't work well like that anyway.)
      - because of bugs in certain builds of PHP, does not function in
        versions lower than 4.3.0 - please upgrade if this hurts you.
