Rewrite Rule Loop. How to stop applying rules - .htaccess

I have an .htaccess file redirecting blog post urls like /blog/2012/11/30/this-post to /blog/post.php?id=this-post. Works fine until I apply a second rule below it that is also a match. This rule is set to take a path formatted url like /this/is/a/pageid and redirect to /page.php?id=pageid. It doesn't care how long the path is, it just uses the last directory in the path as the id. Unfortunately, this rule matches everything and I'm not sure how to stop the redirect after the first match. Here is my .htacess
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^blog/([0-9]+)/([0-9]+)/([0-9]+)/([A-Za-z0-9-]+)$ /blog/post.php?id=$4 [L]
RewriteRule ([^/]+)/?$ /page.php?id=$1 [L]
Thanks in advance for the help.

You can add an optional query parameter after you redirect the first time and combine that with a simple rewrite condition on the query string to check if that parameter exists or no, try this :
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^blog/([0-9]+)/([0-9]+)/([0-9]+)/([A-Za-z0-9-]+)$ /blog/post.php?id=$4 [L]
RewriteCond %{QUERY_STRING} !^(.*&)?r=0(&.*)?$
RewriteRule ([^/]+)/?$ /page.php?id=$1&r=0 [L]

How to mod_write query param to path for arbitrarily long path?

I'm building a simple API with apache and I want to map /really/long/path/api/captions.php?caption_id=blah to /really/long/path/api/captions/blah. It's important to NOT have to specify a full path in the rewrite rule because I want this to work no matter where I deploy this code to. However, I can't find/figure out a working example of .htaccess rewrite rules that enable me to match based upon only the final part of the extension.
So, assuming that I have, say, captions.php in a dir called api, what .htaccess file do I need to include in api to accomplish this transform without having /really/long/path/ anywhere therein?
(I also want to be able to map /really/long/path/api/captions.php to /really/long/path/api/captions/ and /really/long/path/api/captions.)
I've tried all sorts of wildcard-like syntax; here's one of those non-working attempts:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*?)/?captions/(.*?)/?$ /captions.php?caption_id=$1 [L]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /captions\.php\?caption_id=([^\&\ ]+)
RewriteRule ^(.*?)/?captions\.php$ /captions/%1? [L,R=301]
Thanks!
Got there in the end. This is all that was needed:
RewriteEngine On # Turn on the rewriting engine
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^captions/?$ captions.php [NC,L]
RewriteRule ^captions/(.*)/?$ captions.php?caption_id=$1 [NC,L]

Replace items with RewriteRule using .htaccess

I'm trying to use the Url rewrite using "RewriteRule".
I would use this link to show a new article in my blog:
https://www.example.com/article/how-to-visit-italy-in-winter
The original script (including vars) is
https://www.example.com/post.php?idpost=how-to-visit-italy-in-winter
This is my .htaccess
RewriteEngine on
RewriteRule ^article/$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .$ https://www.example.com/post.php?idpost=$1 [L]
but it doesn't work, the browser redirect to:
https://www.example.com/post.php?idpost=
I'm trying to resolve about 2 days witout success :(
Thank you.
You rule looks fine except for two things . Your $1 back reference is undefined and empty as you are not capturing any URI. To capture parts of the uri you need to use Regex capture-groups (.*) .
2) You need to use an absolute path instead of the full url as your RewriteRule`s destination if you want to silently redirect the url.
RewriteEngine on
RewriteRule ^article/$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule article/(.+) /post.php?idpost=$1 [L]

Rewrite and redirect with php variables

I am simply trying to rewrite automatically this:
From: mysite.com/channel.php?id=BBC&name=British Broadcasting Company &date=today
To: mysite.com/channel-britishbroadcastingcompany-today.html
I've tried with:
RewriteRule ^channel-(.*)-(.*)\.html$ /channel.php?id=1&name=$2&date=$3 [R]
But nothing happens.
Hope this simplest one will help you out. This will redirect if
1. REQUEST_URI is /channel.php
2. QUERY_STRING matches this pattern id=something&name=something&date=something
Redirect this to /channel-%1-%2.html here
1. %1 will hold value of name parameter
2. %2 will hold value of date parameter
RewriteEngine on
Options -MultiViews
RewriteCond %{REQUEST_URI} ^/channel\.php$
RewriteCond %{QUERY_STRING} id=.*?&name=(.*?)&date=(.*)
RewriteRule .* /channel-%1-%2.html? [R=301]
As per the requirement specified by OP to first redirect url on html page on the basis of some query parameters then rewriting the request on previous page. So the complete code of .htaccess will be like this.
RewriteEngine on
Options -MultiViews
RewriteCond %{REQUEST_URI} ^/channel\.php$
RewriteCond %{QUERY_STRING} id=.*?&name=(.*?)&date=(.*)
RewriteRule .* /channel-%1-%2? [R=301]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} ^/channel\-(.*?)\-(.*?)
RewriteRule .* /channel.php? [L]
Explanation of 2nd part which is added.
1. REQUEST_FILENAME if file does not exist as a file and directory.
2. REQUEST_URI If request_uri starts with such pattern channel-somewords-somewords
then rewrite request on /channel.php
If I understand the problem correctly, You currently have a file channel.php and what You want to achieve is get more "friendly" URLs for SEO and general aesthetics in the browser location bar but still have channel.php handle your requests.
If this is really the case then You need a two-way rewrite.
First, You need to take your original URL and redirect it to a new, pretty version.
Second, You need to rewrite this pretty URI internally and still feed it to channel.php behind the scenes.
RewriteEngine On
RewriteBase /
# This part rewrites channel.php?name=X&date=Y into channel-X-Y.html
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{REQUEST_METHOD} =GET
RewriteCond %{QUERY_STRING} (.*\&)?name=([^&]+)\&date=([^&]+)(?:\&(.*))?
RewriteRule ^channel.php$ channel-%2-%3.html?%1%4 [R,L,NE]
# This part rewrites it back into channel.php but keeps the "friendly" URL visible
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^channel-(.*)-(.*).html$ channel.php?name=$1&date=$2 [L,QSA]
Note that the first rule-set limits the rewrite to method GET - otherwise You will lose any submitted POST data.
It also allows for any other query-string parameters to surround name and date (the rest of query-string parameters will pass-through to .html URI and then will be picked back up by channel.php)
Also note the ENV:REDIRECT_STATUS rule - this is crucial, without that part You'll be stuck in redirect loop.
See
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-s
RewriteRule ^([a-z0-9-_.]+)/?$ index.php?id=$1 [NC,L]
RewriteRule ^([a-z0-9-_.]+)/([a-z0-9]+)/?$ index.php?id=$1&goto=$2 [NC,L]
What it's going to do is check the index.php and replace to some like, site/dir/index.php to site/dir/namehere than in index.php you can use explode() to separate the values of current url ang get the variables
I am assuming you are asking for rewrite although you are using redirect flag in your current rules, and also assuming BBC to be static in id variable then try with below,
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^channel-([^/]+)-([^/]+).html$ channel.php?id=BBC&name=$1&date=$2 [L]

.htaccess rules to separate page types

I'm having some problems rewriting URLs with the following rules
RewriteEngine on
RewriteRule ^page/(.*)$ index.php?pag=cms&title=$1 [NC]
RewriteRule ^admin/(.*)$ admin/$1 [NC]
RewriteRule ^(.*)$ index.php?pag=$1 [NC,L]
What I'm trying to achieve is to check if the URL is a cms page or not and leave admin URLs as they are.
If I remove the last condition it works but I will have no rule for not cms pages.
Ideally I would want to have just one rule for every page (cms or not) but I can't figure out how to check that other than using page/ in the URL.
Mod_rewrite will keep looping through all the rules until the URI stops changing (or it reaches its internal redirect limit, resuling in a 500 error). You need to add a few conditions to the last rule so that it won't rewrite URI's that's already been properly routed:
RewriteRule ^page/(.*)$ index.php?pag=cms&title=$1 [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?pag=$1 [NC,L]
Additionally, the second rule does nothing except a passthrough, so you can replace it with
RewriteRule ^admin/(.*)$ - [NC,L]
You need these rules:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
From the Apache documentation:
'-d' (is directory)
Treats the TestString as a pathname and tests whether or not it exists, and is a directory.
'-f' (is regular file)
Treats the TestString as a pathname and tests whether or not it exists, and is a regular file.

htaccess does not work rewrite rule

I've been struggling with my .htaccess file for weeks now, I changed it many times but it just won't work.
I have this in my .htaccess file:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^/([^./]+)\.html$ category.php?id=$1
RewriteRule ^/([^./]+)\.html$ tag.php?id=$1
RewriteRule ^/([^./]+)\.html$ play.php?id=$1
but it does not work.
Are you sure that mod_rewrite is turned on in Apache? Do you have access to httpd.conf? It would be better to do redirects there instead of with a .htaccess file.
Your conditions are only being applied to the first rule. Each set of RewriteCond's only get applied to the immediately following RewriteRule. So the conditions only get applied to RewriteRule ^/([^./]+)\.html$ category.php?id=$1 and the last 2 rules have no conditions at all.
Your conditions is to rewrite something that exists to something else, which will cause a rewrite loop. You probably wanted:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
Your 2nd and 3rd rules will never be applied because if someone requests /some-page.html the first rule's regex will match it and rewrite the URI to /category.php?id=some-page, then the next to rules will never match because the first rule already rewrote the URI to category.php.
Your regular expressions match a leading slash, URI's being applied in rewrite rules that are inside an htaccess file has the leading slash stripped out, so you want this instead:
RewriteRule ^([^./]+)\.html$ category.php?id=$1
1, 2 and 4 is easy. 3, not so much. You're going to have to figure out a unique way to represent an html page as a category, tag, or play. You can't have all 3 look identical, there's no way to tell which one you want. Take:
/something.html
Is that supposed to be a category? A tag? or a Play? Who knows, your rewrite rules surely don't. But if you preface each with a keyword, then you can differentiate:
/category/something.html
/tag/something.html
/play/something.html
And your rules would look like:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^category/([^./]+)\.html$ category.php?id=$1
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^tag/([^./]+)\.html$ tag.php?id=$1
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^play/([^./]+)\.html$ play.php?id=$1
