I've got the following ReWrite rule:
add_rewrite_rule("details\/([a-zA-Z0-9_]+)\/.*", "detail/?id=$matches[1]", "top");
Which seems to be adding in the following to my .htaccess, which now looks like this in its entirety:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteRule ^details\/([a-zA-Z0-9_]+)\/.* /detail/?id= [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
This doesn't seem to work. I'm a bit unsure as to why it hasn't put $1 on the end of the rewrite rule. Anyway, I manually added that, and it seems to then be doing something. I can see that the title of the page has changed to that of the rewritten page. The page itself however is still returning a 404 and the standard "OOPS! THAT PAGE CAN’T BE FOUND." message appears.
What have I done wrong?
