I am totally new to this field.I would like to change this url
http://localhost/livelor/profile.php?username=naveen471996
http://localhost/livelor/naveen471996
Yes i did that When url like this is not working 404 Not found
http://localhost/livelor/vikaass.waran
This my .htaccess
RewriteEngine on
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^([^\.]+)$ $1.php [NC]
RewriteRule ^([0-9a-zA-z]+)$ profile.php?u=$1 [L]
RewriteRule ^([0-9a-zA-z]+)
means that just the chars 0-9 a-z and A-Z are allowed
RewriteRule ^([0-9a-zA-z.]+)
should solve the problem and you can use DOT's in the username.
You should have a look at REGEX's
It returns a 404 because it thinks that .warran is the file extension, and fails to load it. To fix this problem, either ban periods (aka dots) from the usernames or use % encoding (http://php.net/manual/en/function.urlencode.php):
$final_url = urlencode($username);
Then, when you want to decode it, use:
$user = urldecode($_GET["username"]);
That way, you'll be able to pass most UTF-8 characters via the $_GET. Be careful about HTML characters (and % codes decodable into HTML characters), though, since that might lead to some hacker issues. Use preg_replace() or something similar to get rid of those before you decode the url.
For a complete list of % codes, visit http://www.w3schools.com/tags/ref_urlencode.asp

I try to realize a system of rewriting URLs in .htaccess.
Then here is my goal:
If I have an url of this form: http://localhost/view.php?Id=456
Then I want to transform it to: http://localhost/456
I use this rule in htaccess:
RewriteRule ^ ([a-zA-Z0-9] +) $ view.php? Id = $ 1
Now this works very well!
But my problem I want to add points to id ie instead of 456 I can put: my.book
That is to say: http://localhost/my.book
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([a-zA-Z0-9\.]+)$ view.php?id=$1 [QSA,L]
You need RewriteCond %{REQUEST_FILENAME} !-f before the RewriteRule line to tell the server that the RewriteRule written below to be executed if the input passed in the URL is not an actual file. Because server searches for a file matching the input you pass in the URL and also it won't work in case you pass my.book in the URL since web server recognizes . as prefix for extension like .php or .html or like so and thereby it results in Not Found error if there is no file named my.book exists. So, you also need to escape . in the URL.
To allow .'s in the input, you need to add . with escape sequence \ in the character class group like ^([a-zA-Z0-9\.]+)$. Note, allowing this can result in escaping the extension in the URL, that is, passing view.php in the URL won't navigate to the actual file. Rather, it will be considered as a value in the query string.
Try this:
RewriteRule ^([a-zA-Z0-9\.]+)$ view.php?Id=$1
Basically what I did is I added \. with your pattern. This will make sure your regex matches any letter (small/caps), decimal numbers and periods (.). Hope this helps :)
I have a url like this :
www.qwerty.in/details.php?vendor_id=1&name=abcd%20cafe
I am trying to conver this like below with the help of .htaccess file :
www.qwerty.in/1/abcd-cafe
I am trying the below but unfortunately its not working . can anyone help
RewriteRule ^([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)$ details.php?vendor_id=$1&name=$2
You character must allow space as well:
RewriteRule ^([\w-]+)/([\w-\s]+)$ details.php?vendor_id=$1&name=$2 [L,QSA]
I have used \w, which is same as [a-zA-Z0-9_].
The following rule will convert your URL from www.qwerty.in/details.php?vendor_id=1&name=abcd%20cafe to www.qwerty.in/1/abcd%20cafe:
RewriteRule ^([^/]*)/([^/]*)\.html$ /details.php?vendor_id=$1&name=$2 [L]
It it much more generalized however, and will convert the first two parameter values even if they are not vendor_id or name. If this is not the behavior you'd prefer, have a look at anubhava's answer.
Converting a space to underscore can be achieved using:
RewriteRule ^(.*)\s(.*)$ $1_$2 [N]
Also, don't forget to ensure the rewrite engine is online:
RewriteEngine On
If you want to further experiment with these rules, I'd recommend a website I recently discovered: http://www.generateit.net/mod-rewrite/
I'm stuck in a very basic thing, I'm try to redirect a single segment url to a page
RewriteRule /([A-Za-z0-9]+)$ index.php?c=profile&val=$1 [NC,L]
this works fine for URLs like
sitename.com/myurl
But the problem is its also valid for URLS like
sitename.com/myurl/something
or
sitename.com/myurl/something/x/y/z
I want it to only work for single segment after hostname, if I use it with ^ sign at the start it don't work at all
Any help would be greatly appreciated.
Thanks
You still have to use ^, but must leave out the leading /
RewriteRule ^([A-Za-z0-9]+)$ index.php?c=profile&val=$1 [NC,L]
For compatibility with older mod_rewrite versions you often see idioms like ^/?. But current Apaches mod_rewrite strips the leading slash already (from the REQUEST_URI which RewriteRules operate from primarily).
Consider the following scenario:
I want to be able to access http://www.example.com/word/hello/, where the word hello is variable. So I set up .htaccess to configure that.
RewriteEngine On
RewriteRule ^word/(.+)/?$ displayword.php?word=$1 [L]
I used .+ because I also want to filter any symbols such as ?+-.!;: etc.
And I set up my PHP file accordingly:
<?php
echo $_GET['word'];
?>
Remember that this is just a scenario. Now, I went to this URL: http://www.example.com/word/Are you ok?/, and the page outputted this:
Are you ok
And I couldn't figure out why. But then I realised that the question mark symbol is the starting point of the URL variables.
So is there a way to 'url encode' the question mark in the above example, in order for it to be displayed correctly?
There is no need to encode it, try this:
RewriteEngine On
RewriteRule ^word/([a-zA-Z0-9-=_.?]+)/?$ displayword.php?word=$1 [L]
It will display ? in the parameter and any other character you add to the [group]. I did not test if the rule works, though, but I suppose it does. Looks ok and that is not the question.
I don't know heaps about .htaccess files, but you could change your PHP script to use $_SERVER['PATH_INFO'] instead of $_GET or $_REQUEST.
Particularly, this comment might help you out.
In the HTTP protocol the "?" separates the querystring from the rest of the URL, so I don't think it will be possible to use it directly inside the URL. One solution would be to encode the question mark into %3F.
Then you can use string urldecode (string $str) to decode the string.
See this URL Encoding Reference for the encoding of other characters.
Change your code to this:
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+word/([^/]+) [NC]
RewriteRule ^ index.php?word=%1 [L,QSA]
Reason this works is because RewriteRule works on %{REQUEST_URI} which gets URI i.e. string before question mark ? however %{THE_REQUEST} works on the full URL that includes question mark ? as well.
I'm using mod_rewrite to transfer the end of the URL to my php script which will act as a microcms. My url will look something like this:
mysite.com/articles/some-article-about-css
That will pass the following to my PHP script index.php:
index.php?action=read&article=some-article-about-css
I have questions:
I'm unsure how the best way to only accept alphanumeric w/ dashes using mod_rewrite. I found this rule on the internet ((?:[a-z]+)?(?:[0-9]+)?-?)+ and it apparently doesn't allow double dashes which is even better, but its long and confusing. Is there another (shorter, faster) rule I can use?
I'd like to verify that this rule is valid for what I'm trying to accomplish. I'm not very good with mod_rewrite:
RewriteRule ^/articles/((?:[a-z]+)?(?:[0-9]+)?-?)+ /index.php?action=read&article=$1
What rule can I use so that if the url after /articles/ is not a valid alphanumeric /w dashes url, automatically throw a 404 rather than passing to my script?
RewriteRule ^/articles/([a-zA-Z0-9-]*) /index.php?action=read&article=$1 [QSA,L]
RewriteRule ^/articles/ - [R=404]
For alphanumeric and dashes only
You dont need that complex regex i believe. Try this
RewriteRule ^articles/([^a-zA-Z0-9-]*) /index.php?page=$1 [L]
RewriteRule ^articles(.*) [R=404]
