.htaccess - changing urls - RewriteRule not working - .htaccess

Question

I'm fairly new to this, hopefully you can help me fix this problem.
I have a URL structure that gets an id from a database and shows the url like this:
www.website.com/post.php?P=18
I would like to present the URL's as:
www.website.com/post/18
In my .htaccess file, I've altered it like so:
RewriteEngine on
RewriteRule ^post/(\w+)$ post.php?P=$1
I've read through a few posts about this here on SO but I can't seem to figure it out.
I followed this:
The Rule:
RewriteRule ^user/(\w+)/?$ user.php?id=$1
Pattern to Match:
^ Beginning of Input
user/ The REQUEST_URI starts with the literal string "user/"
(\w+) Capture any word characters, put in $1
/? Optional trailing slash "/"
$ End of Input
Substitute with:
user.php?id= Literal string to use.
$1 The first (capture) noted above.
Thank you!

Answer 1

Try with below,
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^post/(\w+)$ post.php?P=$1 [L]

Answer 2

I think it's important to share this kind of information for others that may be having the same issue so here goes.
The Problem:
[1] A link that looked like: www.example.com/news.php?P=1
The link should look like www.example.com/news/1
Then, the link would have to end up showing text instead of an ID. www.example.com/news/news-name
The solution
First, i had anchor tags that looked like this
It gave the first result in the URL [1]. To change it so it would present as a www.example.com/news/1, i had to do the following:
Create a htaccess file and fill it like this:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php [NC]
### THIS IS AN EXAMPLE FOR MULTIPLE EXPRESSIONS ###
#RewriteRule ^news/([0-9]+)/([0-9a-zA-Z_-]+) news.php?P=$1&name=$2 [NC,L]
RewriteRule ^news/([0-9]+) news.php?P=$1 [NC,L]
And then, change the anchor tags to:
[1] Would be done now.
The challenge now was to use a slug instead of an ID. On the post creation page, I added the following PHP:
<?php
setlocale(LC_ALL, 'en_US.UTF8');
function slugit($str, $replace=array(), $delimiter='-') {
if ( !empty($replace) ) {
$str = str_replace((array)$replace, ' ', $str);
}
$clean = iconv('UTF-8', 'ASCII//TRANSLIT', $str);
$clean = preg_replace("/[^a-zA-Z0-9\/_|+ -]/", '', $clean);
$clean = strtolower(trim($clean, '-'));
$clean = preg_replace("/[\/_|+ -]+/", $delimiter, $clean);
return $clean;
}
?>
Then, on the news insertion page, I added: $slug = slugit("$entry1");, which would pass $entry1 = $_POST['title']; as the title of the page, but slugified. On the database for the news, i created a column to accommodate $slug as a permalink name.
Now to present the URL with the slug, I had to change the anchor tag to:
And on the htaccess, change RewriteRule ^news/([0-9]+) news.php?P=$1 [NC,L] to RewriteRule ^news/([0-9a-zA-Z_-]+) news.php?P=$1 [NC,L]
That's how I got it to work. I hope this will help people with similar problems fix theirs.
