I am about to attempt writing of a photo sharing script and a script/rewrite that transforms numbers into descriptive names. I have a vague idea on how to go about doing this, so I was looking for some general comments/guidance.
Issue 1: I need to have a URL source for a photo which is stored above my root directory. I plan on appending the photo name (which is stored in my database) to my url as a query string, such as: www.mywebsite.com/getphoto.php?12_3.jpg and then writing a php script (getphoto.php) which takes the portion after the '?' and gets that photo from above the root.
Does this make sense and would there be any things to consider?
Issue 2: I want to transform a number at the end of my URL to a descriptive name (ie typing in facebook.com/4 displays facebook.com/zuck). I am not really sure the best way to go about doing this and was hoping for some guidance to get going in the right direction.
Thanks!
For Issue 1: a simple rewrite can handle that, you need to use the [QSA] flag. Something like this:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} ^.*\.(jpeg|jpg|gif|png|bmp)$
RewriteRule ^(.+)$ /getphoto.php?photo=$1 [L,QSA]
This will rewrite behind the scenes the url http://mywebsite.com/12_3.jpg to http://mywebsite.com/getphoto.php?photo=12_3.jpg Note that the 3rd rewrite condition wants the URI to end with an image extension, you may not need it.
For Issue 2, it depends on how something like "4" maps to "zuck". If you are going to hardcode them into your apache config, you can use a RewriteCond:
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/4$
RewriteRule ^.*$ /zuck [L]
RewriteCond %{REQUEST_URI} ^/5$
RewriteRule ^.*$ /mark [L]
etc. (or replace [L] with [R,L] to redirect instead of rewrite, or alternatively just use Redirect)
Redirect /4 /zuck
Redirect /5 /mark
etc.
If the mapping is stored in a database, your going to need to do this dynamically, perhaps as a php script to do a redirect, utilizing something similar to Issue 1. The rewrite rule would rewrite to something like /redirect.php?id=$1 and your redirect.php script would take the id and do a database lookup to see where to redirect the browser.

I am deciding to create separate profile links for each user who registers on the website. I am using the .htaccess file RewriteRule to achieve this. The url I want to achieve should look something like www.domain.com/username. (I don't want www.domain.com/users/username)
Now the problem is, if I add a rule like RewriteRule ^(.*)$ /users.php?username=$1
it will matchup all URL addresses for www.domain.com, which may direct to any path. Even if I would like to visit www.domain.com/about page, it will be redirected to
www.domain.com/users.php?username=about, which I don't want. (Even if the requests was www.domain.com/products/abc)
I could apply filters in my users.php to filter such usernames, or if a username is not found in database, redirect to the page, but this means I have to change filters every time I decide to add a new page in my directory (in this case, any). Also, all traffic will be directed through 1 page, which may cause a performance problem.
Please suggest a way to achieve this, as There are websites that work like this. A possible RewriteRule or PHP code to achieve this.
You can use this rule in your root .htaccess:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(\w+)/?$ /users.php?username=$1 [L,QSA]
I always use just simple rewrite as below:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*)(.*)/?$ index.php
All traffic is redirected to index.php and using php I can run specific controllers depending on url. You should also think about. Almost all frameworks use such rule.
Then in your PHP file you should examine
$_SERVER['REQUEST_URI']
variable to route request to specific controllers
I think that I am trying to achieve an impossible result.
The scenario is PURL-Mailing and I already got some URL's rewritten to fit the URL, sent to the customer.
The customer enters the site by the following domain: http://domain.com/UserName
The Variable UserName represents the GET-Variable, which equivalent to http://domain.com/index.php?user=UserName
I achieve this with the following rewrite Rules:
RewriteBase /
RewriteRule ^([a-zA-Z0-9_-]+)$ index.php?name=$1 [QSA]
#This works perfect and translates to http://domain.com/UserName
RewriteRule ^([a-zA-Z0-9_-]+)/$ index.php?name=$1 [L]
#This achieves the goal but does not reflect in the URI I want:
#http://domain.com/UserName
To go further, there are also some Names containing a dot in the Name like A.Jackson that also need to be treated as UserName. As those are only 13 Name I could implement them manually. What I don't know is how I can prevent the part after the dot to be handled as a file extension. Is there a way to write a custom handle in *mod_rewrite* for those?
And if so, can anybody explain to me how?
Thanks in advance and best regards!
ok try below
RewriteCond %{REQUEST_FILENAME} !(img|anyother folders that you want to ignore|anyother folders that you want to ignore|...)
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule ^([a-zA-Z0-9_-]*[\.]*[a-zA-Z0-9_-]+)[/]*$ test.php?name=$1 [L]
replace 'anyother folders that you want to ignore' with folder name that you want to ignore. Seperate each folders with '|'
You also have to provide full path to the CSS, image or any other links used in your web page when you using URL rewrite functions
Here is your fix
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule ^([a-zA-Z0-9_-]*[\.]*[a-zA-Z0-9_-]+)$ index.php?name=$1 [L]
I'll be signing businesses up to advertise on my website, and I want them to have a direct URL for their customers to go to.
Like, instead of www.website.com/page.php?id=324234234,
I want to have www.website.com/businessname
Is there a simple way to do this? I've searched and seen a whole bunch of different things people are trying to do but I haven't seen anything that's the same as what I want to do.
I'm using a VPS, and I want to make sure that I don't open up permissions so that anyone can get in there and mess things up.
Also, these users will not be signing themselves up. I will be doing that.
The simplest way to get my end result is what I'm looking for. Thanks!
Basic URL rewriting could work.
Add to your .htaccess file
RewriteEngine on
RewriteRule ^(.*)$ page.php?businessname=$1 [L]
Then use PHP to rewrite the businessname to the ID of the company / find the data.
Of course .htaccess rewrite rules is a complete science if you need more complex rewriting...
Re-iterating what jtheman said with a little more explanation:
Create a file named .htaccess with the contents:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ page.php?businessname=$1 [L]
You need, of course, the ability to have directory level .htaccess enabled - you're using a VPS so you should be able to do this if it is not already enabled.
So let me explain what each line will do.
RewriteEngine on
Turns on the ability to URL re-write
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
Tells Apache not to re-direct files that exist in the directory already
RewriteRule ^(.*)$ page.php?businessname=$1 [L]
This is where the magic happens.
^(.*)$ this part is like a regular expression match. It will tell Apache to collect any URLs that have any characters within them and redirect them to page.php?businessname=(.*)
So, if you post:
www.website.com/stackover
It will really be sending: www.website.com/page.php?businessname=stackover
Then you can just use $_GET[businessname] to dynamically update the page.
Hope this helps!
I am trying to capture a url such as
http://www.mysite.com/somepage.php?sometext=somevalue
and redirect it to.
http://www.mysite.com/index.php?page=somepage.php&sometext=somevalue
I tried searching for such .htaccess online, but couldn't find it.
Can you please help me?
I'm quite sure this is a duplicate, but I'm having a bit of an issue finding it/them [Edit: I found one, though possibly not the best example].
Anyway, this is a fairly standard problem resolved with fairly standard code:
RewriteRule ^(.*)$ index.php?get=$1 [L,QSA]
The RewriteRule captures the entire request as $1, and passes it to index.php as the page GET parameter.
The [QSA] flag on the end says to take any existing GET parameters (sometext=somevalue in your example), and add them as additional GET parameters on the new request. (The [L] flag just says that this should be the last rule executed.)
Note that this will also redirect requests for things like images or CSS files, so it's good to add the following lines directly before this rule:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
These lines say "if the request is for a file or directory that actually exists, don't process the rule." That way, requests for real files will be served directly by Apache, rather than being handled (or more likely, mishandled) by your PHP script.
RewriteRule ^(.*).php?sometext=(.*)$ index.php?page=$1.php&sometext=$2 [QSA,L] #rewrite
RewriteRule ^(.*).php?sometext=(.*)$ http://www.mysite.com/index.php?page=$1.php&sometext=$2 [R=301,L] #redirect
I'm lost here. I'm using this script to give users the opportunity to enter their username lijke this:domain/username
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/?$ userpage.php?user=$1 [NC,L]
</IfModule>
This works fine. However, every user has pages I must link to: Video, Music, Images etc...
So I need something like:
domain/username/video
In php code it must be something like:
user.php?user=test&page=video
And one other question: What is the preferable way to link in this situation?
userpage.php?user=test&page=video
or
/test/video
And finally: Is it possible to deny the possibility to enter the url:
domain/userpage.php?user=test&page=video? Instead just always show: domain/test/video
Thanks in advance
I'm not 100% sure what you're asking? Do you need to change the rewrite rule to match the URL site.com/moonwalker/videos? You could try this:
RewriteRule ^([^/]+)/(images|videos|music)/?$ userpage.php?user=$1&page=$2 [NC,L]
Update
Just a quick note on the domain/member/videos URL structure. That could end up causing you problems in the future. For instance what if you decide to have a single page that shows all member videos? You'd probably want to URL to look something like site.com/members/videos. That's a problem, because the rewrite rule will also match that, but "members" isn't a member username.
I would probably structure my member page URLs like site.com/user/moonwalker/videos so it doesn't clash with future rewrite rules. You would change the above rewrite rule to this:
RewriteRule ^user/([^/]+)/(images|videos|music)/?$ userpage.php?user=$1&page=$2 [NC,L]
Then later on you can add a rewrite rule like:
RewriteRule ^members/(images|videos|music)/?$ allusers.php?page=$1 [NC,L]
To show all member videos.
Yes, it is possible by looking at the request line:
RewriteCond %{THE_REQUEST} ^[A-Z]+\ /userpage\.php[?\ ]
RewriteRule ^userpage\.php$ - [F]
This is necessary as the URL path could already be rewritten by another rule and thus using just RewriteRule would match those already rewritten requests too.
