Permalink "bug" workaround

[gregman]

Hi Folks,

when setting up my new blog, I experienced a strange behaviour of s9y when I changed the permalink structure for the articles from ..."%id%-%title%.html" to ..."%title%.html" (just removing the "%id%-" tag for seo reasons).

When I entered a new article with a title containing only one word (e.g. "spaceship") the entry could not be displayed. It only appeared the message "Keine Einträge vorhanden". Therefore I gave a closer look to the .htaccess file and examined some kind of confusion of the rules. It seemed to me that the first rewrite rule didn't fit to permalinks with only one word in the title and no id. Therefore I changed the permalink rule to ..."%title%.htm" (just ".htm" not ".html") and guess what. It worked!

Maybe someone who is more experienced in mod rewriting has a solution for a modification of the first rewrite rule starting with "^((" so that it will fit for ".html" endings as well.

Best regards
Greg

Hi!

Could you maybe post your full .htaccess, then I could easier try to see what's happening?

Hi Garvin,

of course. The blog I'm working on, is not ready to be published, but I found out that the same "bug" appeared on another blog of mine. Here's the code:

Code: Select all

# BEGIN s9y

php_value session.use_trans_sid 0

Hi!

if you reomve the first rewrite rule, everything works as expected, right?

I'll try to see, I think the matter is because the one pattern redirects to index.php?/blabla and the other to index.php?url=/blabla...

Hi,

no, removing the first rewrite rule doesn't change anything. Neither does removing all of them. Pretty confusing for me, because I dont really understand why they are needed. As far as I can see I would expect the line

Code: Select all

ErrorDocument 404 /index.php

to be the reason for the missbehaviour. Something like "If the url is not found load index.php" and "index.php" may examine the url and tries to get the entry?

Hi!

Which s9y version do you use? Can you try s9y 1.3? I just saw that we changed the format of the .htaccess there. By upgrading, you can change the permalinks, save the configuration (.htaccess will be updated then to the new format), that should hopefully work.

It changes "index.php?url=..." to "index.php?/...".

Hi,

so I updated the blog to the 1.3 alpha1 version, but it didn't change a lot. Now, after removing the %id%- from the permalinks configuration option, titles which contain only one word are still not clickable. A page appears, that shows any entry starting with the second last. Renaming the ".html" to ".htm" in the permalinks configuration option does still solve the problem.

Hi!

Did s9y update the .htaccess for you (have a look at the modification date). Only some changes trigger s9y to update that file...

Did s9y update the .htaccess for you (have a look at the modification date).

Yes, sure: the modification date is 2008-01-20. When I ment, I updated the software, I made myself not clear enough. Actually, I did a complete and whole new installation. I can't imagine that I'm the only one with this problem. But it seems to be so, as no other follows this discussion...

here again the code of my .htaccess file:

Code: Select all

EDIT: And again, I think it must be a problem within the index.php, because also switching off the whole Rewrite Engine doesn't have any effect.

[garvinhicking]

Hi!

Could you show us the URL to the mentioned blog?


Does it work if you change:

Code: Select all

RewriteRule (.*\.html?) index.php?url=/$1 [L,QSA]

to

Code: Select all

RewriteRule (.*\.html?) index.php?/$1 [L,QSA]

Hi,

no the suggested code doesn't change anything. I'm still designing the blog local, so it isn't online yet. Besides: I also want/have to change the permalinks to parentcategory/category/title.html, so I have to rewrite the .htaccess completely and may get rid of the "bug" then.

Greg

Hi!

Hm, I'm afraid I can only try to check some things when I can get to the URL of the blog...maybe once you put it temporarily online?

Ah, for that you'd have to patch core s9y code - the feature does not exist to put a "nested" Category-permalink URL... (if you want to have proper automatic category url creation, of course - manually it will be sufficient to patch .htaccess)

Garvin

[gregman]

Hi Garvin,

I'm stuck with my attempts to change the category permalink structure and hope you can give me a hint.

At first I wanted to get each parent category automatically by a new function. Because of a heavy performance loss I dumped this solution and decided to "fake" the link structure by renaming each category to "parencategory/category" (e.g. formerly category name "augsburg" in parent category "bayern" changed to "bayern/augsburg"). Therefore I changed the PAT_FILENAME definition in the functions_permalinks.inc.php to keep the slash, but for some reason the permalink ...categories/bayern/augsburg doesn't work. It displays all entries, not only the one from the specific category "bayern/augsburg".

Any suggestions?

Thx, Greg

EDIT: Got it! I missed to alter the permalink configuration as well. Now it works.

[gregman]

OK,

besides my research with the parent categories / categories structure I found the cause, why entries with a "one word only html-title" (e.g. spaceship.html) won't be displayed, when no %id% is given to s9y. The URI then matches the PAT_ARCHIVES pattern in index.php (the "more than one word titles" don't match this pattern because of the "-" in the uri).

Greg

EDIT: I just had a look at the PAT_ARCHIVES pattern. Is there any possibility to get the arives pattern different from one word entry titles? Does every archives url end on a number?

[gregman]

Hi,

would

Code: Select all

$PAT['ARCHIVES']                 = '@/'  . $serendipity['permalinkArchivesPath'].'([/0-9C]+)\.html@';

be an adequate replacement for the ARCHIVES PATTERN in functions_permalinks.inc.php? I searched a bit within my blog and it seems to me that archive urls either consit of numerical chars and a slash or numerical chars, a slash and a "C" when displaying a category archive.

Greg
