ReWrite Rules htaccess confusion - .htaccess

So I am new to the ReWrite Rules in htaccess and could use some help
I currently have a php page poll.php base template for the information it gets from PHPMyAdmin gets the information for the poll through the pollcode for this example it will be vmxez so poll.php?code=vmxez displays correctly how I want it to but I am trying to rewrite it so domain.com/vmxez shows what is on domain.com/poll.php?code=vmxez any help would be great been fighting this one for 2 hours.

Assuming the rewrite module is installed and enabled,
# Turn on the rewrite engine
RewriteEngine On
# Set the base path
RewriteBase /
# Rewrite an exact match of /vmxez
RewriteRule ^/vmxez$ /poll.php?code=vmxez
If your goal is actually send all non-PHP script requests to poll.php:
# Skip rewrites for direct file requests (e.g. PHP scripts)
RewriteCond %{REQUEST_FILENAME} !-f
# Capture the path requested and pass it as a parameter
RewriteRule ^(.+)$ /poll.php?code=$1

how to rewrite SEO URL

I am just new to .htaccess.
I need some rewrite rules for URLs.
I Google'd some and applied but no change in URL.
I want:
demo.example.com/files/section.php?id=1
Changed to:
demo.example.com/sample-section
I tried
Since you use .htaccess I assume you are using Apache. Here you'll find all relevant documentation.
First of all you need the mod_rewrite module to be installed (instructions to do so depend on the server's operating system and Apache distribution).
Then, the URL rewrite is pretty simple:
# First of all tell to mod_rewrite to operate.
RewriteEngine on
# Then, as many times you need, tell it on what to operate...
# For example: on files that do not exist. Or leave out RewriteCond to act on all.
RewriteCond "%{REQUEST_FILENAME}" !-f
# ...and what to do.
RewriteRule /sample-section "/files/section.php?id=1" [PT]
RewriteRule /another-section "/files/section.php?id=2" [PT]
The PT (PassThru) flag might be needed in some contexts, otherwise just use [L].

.htaccess cans and can'ts

I am very new to the idea of .htaccess and thought that it was what you used to do something like turn this:
http://www.domain.com/some/ugly/url/here.html
into this:
http://www.domain.com/niceurl
I was just told by my ISP that in order to get that to happen, no, it's done by putting the document into the web root folder. That .htaccess isn't used at all.
Does anyone know if this is true? I see a lot of examples about what .htaccess DOES but not so much about what it can't do. Somehow I thought this was all that was needed.
Lastly, if someone types in www.domain.com/niceurl what will happen? Don't I need to have that linked (if not by htaccess, how?!) to the location of the actual file?
Thank you for any and all help. I realize that .htaccess questions abound but they're hard to pick through for the layperson and I'm hoping to answer this specific question.
Here's what I believe should be an answer you want, put the block below to your .htaccess
Answer:
## Enabling Apache's Mod_rewrite module.
RewriteEngine On
# Following line is required if your webserver's URL is not directly related to physical file paths (just / for root, e.g. www.domain.com/)
RewriteBase /
# Restricts rewriting URLs only to paths that do not actually exists
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
# Redirect www.domain.com/bar to www.domain.com/foo
Redirect 301 /bar /foo
# Internally load the long URL without changing URL in address bar
RewriteRule ^foo/?$ http://www.domain.com/some/ugly/long/thing/here.html [L,NC]
As a result, www.domain.com/bar will be redirected to www.domain.com/foo and /foo will internally load http://www.domain.com/some/ugly/long/thing/here.html
FYI:
Your website's URL doesn't have to be directly related to physical file paths. Your URL's segment can be served as alias to your URL's parameters. for e.g,
http://www.domain.com/index.php?key1=value1&key2=value2
can be represented as
http://www.domain.com/value1/value2
Note: you need to implement a server side script to be served as a
router to manipulate the URL segments.
For more information about using .htaccess, check this out
Ref: http://htaccess-guide.com/
.htaccess files can be used to alter the configuration of the Apache Web Server software to enable/disable additional functionality and features that the Apache Web Server software has to offer. These facilities include basic redirect functionality, for instance if a 404 file not found error occurs, or for more advanced functions such as content password protection or image hot link prevention.
Below is a few examples,
# Custom Error Pages for Better SEO,
# for e.g, to handle 404 file not found error
ErrorDocument 404 http://www.domain.com/404page.html
# Deny visitors by IP address
order allow,deny
deny from 122.248.102.86
deny from 188.40.112.210
allow from all
# Redirects
Redirect 302 /en/my-dir/my-page.html /en/my-path/example.html
# Disallow some silly bots from crawling your sites
RewriteCond %{HTTP_USER_AGENT} (?i)^.*(BlackWidow|Bot\\ mailto:craftbot#yahoo.com|ChinaClaw|Custo|DISCo|Download\\ Demon|eCatch|EirGrabber|EmailSiphon|EmailWolf|Express\\ WebPictures|ExtractorPro|EyeNetIE|FlashGet|GetRight|GetWeb!|Go!Zilla|Go-Ahead-Got-It|GrabNet).*$
RewriteRule .* - [R=403,L]
# Setting server timezone
SetEnv TZ America/Los_Angeles
# trailing slash enforcement,
# e.g, http://www.domain.com/niceurl to http://www.domain.com/niceurl/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !#
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ http://www.domain.com/$1/ [L,R=301]
Enable mod_rewrite and .htaccess through httpd.conf (if not already enabled) and then You can use this code in your DOCUMENT_ROOT/.htaccess file:
RewriteEngine On
RewriteRule ^niceurl/?$ some/ugly/url/here.html [L,NC]
This will allow you to use http://domain.com/niceurl in your browser and it will internally load http://domain.com/some/ugly/url/here.html without changing URL in browser.
If you also want to force redirection from ugly URL to pretty URL then add this redirect rule just below RewriteEngine On line:
RewriteCond %{THE_REQUEST} \s/+some/ugly/url/here\.html [NC]
RewriteRule ^ /niceurl [R=302,L,NE]

Rewrite URL and remove part with .htaccess

I am really stuck with my .htaccess file, and need some help :). I have a WordPress installation that I am using for testing. It is in a folder and I use .htaccess to get there. This is the rules I use so far:
######### Custom #########
RewriteEngine On
# ignore folders
RewriteCond %{REQUEST_URI} "/af1wp/"
RewriteRule (.*) $1 [L]
###############
# only for me #
###############
# HOME (Senne Tijdeman)
RewriteCond %{REMOTE_ADDR} ^###\.###\.###\.###$
RewriteCond %{HTTP_HOST} ^((www.)?([a-z0-9_\-]+).)?alleenf1.nl$
RewriteCond %{REQUEST_URI} !^/af1wp/$
RewriteRule ^(.*)$ /af1wp/$1 [L]
This works (with my real IP address of course), so no problem there. But now I want to rewrite exisiting URL's to a new format. The old URL is this:
http://alleenf1.nl/nieuws/QOgbb/raikkonen-alles-is-mogelijk-in-australi
The new URL should be this:
http://alleenf1.nl/raikkonen-alles-is-mogelijk-in-australi
The part I want to remove "nieuws/QOgbb/" is not always the same, so I have to use regex for that. But everything I tried did not work at all.
I thought this would be simple, but apparently not for me unfortunately. Now I have 2 questions.
What is the right RewriteRule to do this?
Where should I put it. In the .htaccess of the root folder, or the af1wp folder where the WordPress install is?
Tnx in advanced
To awnser the questions from poncha below:
Yes, the URL's always start with to folders. Just to clarify (was not clear) the part "nieuws" is always the same, but not the second part (call it an ID).
I prefer a redirect.
The file /raikkonen-alles-is-mogelijk-in-australi is a post in WordPress. That WordPress installation currently resides in the folder af1wp, but will be moved to the root folder when going live.
Try this:
RewriteEngine On
RewriteRule ^nieuws/([^/]+)/(.*) /af1wp/$1 [R=301,L,QSA]
This will only match URLs starting with "nieuws"
For now, the rewrite target is /af1wp/, change it to / when moving the wordpress.
When you move wordpress, you'll need to mix in this rule inside the wordpress rules, as it already has rewrite rules of its own - place this rule above its rules.
The flags used here:
R=301 - redirect with HTTP status 301 (Moved Permanently).
L - last rule (stop rules parsing after successful match of this rule)
QSA - query-string-append (append original query string to the rewritten request).

Using mod_rewrite to mask a directory/file name in a URL

I've taken my site down for some prolonged maintenance and am using mod_rewrite to send all requests to a single page: www.mysite.com/temp/503.php
This is my .htaccess file which works fine.
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !^/temp/503.php [NC]
RewriteRule .* /temp/503.php [R,L]
However, what I'd also like to be able to do is to hide /temp/503.php in the resulting URL from the visitor.
I know this is perhaps trivial and I'm sure fairly simple to achieve, but with my limited mod_rewrite skills I can't seem to get it to work.
Any help would be much appreciated.
Thanks.
Just get rid of the R flag in the rewrite rule, which tells the rule to redirect the request, thus changing the URL in the browser's location bar. So the rule would look like:
RewriteRule .* /temp/503.php [L]
which internally rewrites the requested URI instead of externally telling the browser that it's been moved to a new URL.

Redirect to fallback file if first attempt fails

I have this in my .htaccess:
RewriteRule ^images/([^/\.]+)/(.+)$ themes/current/images/$1/$2 [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^images/([^/\.]+)/(.+)$ modules/$1/images/$2 [L,NC]
The idea is that it does the following:
// Rewrite this...
images/calendar/gear.png
// ... to this
themes/current/images/calendar/gear.png
// HOWEVER, if that rewritten path doesn't exist, rewrite the original URL to this:
modules/calendar/images/gear.png
The only things that change here are calendar and gear.png, the first of which could be any other single word and the latter the file name (possibly with path) to an image file.
I can rewrite the original URL to the first rewrite as shown in the example just fine, but what I cannot do is get my .htaccess to serve up the file from the other, fallback location if the first location 404s. I was under the impression that not using [L] in my first RewriteRule would rewrite the URL for RewriteCond.
The problem I'm having is that instead of serving the fallback file, the browser just shows a 404 to the first rewritten path (themes/current/calendar/gear.png), instead of falling back to modules/calendar/gear.png. What am I doing wrong?
Please note that my regex isn't perfect, but I can refine that later. Right now I'm concerning myself with the rewrite logic itself.
Fallthrough rules are fraught with bugs. My general recommendation is than any rule with a replacement string other than - should trigger an internal redirect to restart the .htaccess parse. This avoids the subrequest and URI_PATH bugs.
Next once you go to 404, again in my experience this is unrecoverable. I have a fragment which does something similar to what you are trying to do:
# For HTML cacheable blog URIs (a GET to a specific list, with no query params,
# guest user and the HTML cache file exists) then use it instead of executing PHP
RewriteCond %{HTTP_COOKIE} !blog_user
RewriteCond %{REQUEST_METHOD}%{QUERY_STRING} =GET [NC]
RewriteCond %{ENV:DOCUMENT_ROOT_REAL}/blog/html_cache/$1.html -f
RewriteRule ^(article-\d+|index|sitemap.xml|search-\w+|rss-[0-9a-z]*)$ \
blog/html_cache/$1.html [L,E=END:1]
Note that I do the conditional test in filesystem space and not URI (Location) space. So this would map in your case to
RewriteCond %{DOCUMENT_ROOT}/themes/current/images/$1/$2l -f
RewriteRule ^images/(.+?)/(.+)$ themes/current/images/$1/$2 [L]
Though do a phpinfo() to check to see if your hosting provider uses an alternative to DOCUMENT_ROOT if it is a shared hosting offering e.g an alternative environment variable as mine uses DOCUMENT_ROOT_REAL.
The second rule will be picked up on the second processing past after the internal redirect.
