 Posted: Wed Jan 24, 2007 10:39 pm Post subject: Help converting .htaccess |
 |
|
Hello
I'm trying to learn the Code Igniter framework to write web apps in PHP. It requires using an .htaccess to remove index.php from the URL to get cleaner addresses (eg. http://localhost/index.php/myctrl to http://localhost/myctrl).
Would an experienced and kind soul tell me how to rewrite the following file to its equivalent in Abyss X1?
| Code: |
RewriteEngine on
RewriteRule ^$ index.php [L]
RewriteCond $1 !^(index\.php|assets|search)
RewriteRule ^(.*)$ index.php/$1 [L]
|
Thanks ! |

I believe this is done with the url re-writing, it is to my knowledge that abyss does not use .htaccess files, incase the URL re-writing dosent work

Thanks. Turns out that the latest version of Abyss (2.4) supports URL rewriting, although not through .htaccess, so I must understand what the above means. FWIW, I found it in the archives in the CI forum, as the one given in the online documentation didn't work for me.
Can someone confirm that | Code: | | RewriteRule ^$ index.php [L] |
means that any URL for the directory in which .htaccess is located that doesn't have index.php explicitely written, eg. http://localhost/igniter, will be replaced with http://localhost/igniter/index.php?
And as far as the second part is concerned, I googled for RewriteCond, but didn't find an explanation as to what $1 stands for in | Code: | | RewriteCond $1 !^(index\.php|assets|search) |
: Does it refer to the entire URL?
If yes, I understand that it means that if it doesn't find either "index.php", "assets", or "search" in the URL, then it will be rewritten by prepending index.php to the URI.
Thanks. |

More information to investigate: URL Rewriting doesn't even work with the following basic example:
/toto/ Perform an internal redirection /titi/ Stop matching
Virtual Path Regular Expression = /toto/
Conditions = Empty
If this rule matches = Perform an internal redirection
Redirect to = /titi/
I get a Error 500 Internal Server Error
FWIW, /www/titi/ does exist and contains an index.html :-/ |

littlebigfred,
Turn URL rewriting logging/debugging on to understand what's going on and how your request is being interpreted/translated.
In
| Code: | | RewriteCond $1 !^(index\.php|assets|search) |
$1 is backreference resulting from matching the RewriteRule so it could be replaced by ${REQUEST_URI} (since the RewriteRule regular expression is ^(.*)$ ).

Thanks, I didn't see I could log those. Turns out that REQUEST_URL didn't work, and I should use REQUEST_URI. The redirection with /toto/ and /titi/ works now :-)

I'm puzzled about $1 here. Here's a simplified alternative that I saw mentionned in the Code Igniter forum:
| Code: |
RewriteEngine on
RewriteRule ^$ index.php [L] <- no ()!!!
RewriteCond $1 !^(index\.php|assets|search) <- $1 ???
RewriteRule ^(.*)$ index.php/$1 [L]
|
Does it mean that $1 is referring to the RewriteRule on the line right above it? How come?
I finally got Code Igniter to work with the following:
^/igniter/(.*)$
//Note the ? after index.php
Perform an internal redirection /igniter/index.php?/$1
Continue with the next rule
BTW, out of curiosity, how would I do the following with Abyss:
| Code: |
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
|
Thanks! |

That's the magic of mod_rewrite syntax. A vague explanation of that is available in its manual and reading the source code of the module shows that it processes the RewriteRule first, sets backreferences, and then makes them available when validating conditions.
| Code: |
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
|
The conversion of that rule is straightforward: Create a new rule as follows:
* Virtual Path regular expression: ^(.*)$
* Conditions:
- Condition 1:
REQUEST_FILENAME is not a file
- Condition 2:
REQUEST_FILENAME is not a directory
* Set "If this rule matches" to "Perform an internal redirection"
* Set "Redirect to" to /index.php/$1

Congratulations, Aprelium. My websites at the office internal LAN work phenomenally flawless and so I don't get to visit back here much often anymore. I'd be willing to lend a helping hand in the following days and weeks as time permits, especially in the areas of URL-rewrites whenever I can. maybe you can set you can set up a different topical forum devoted to setting up URL-Rewrites?
