Why .htaccess mod_rewrite does not show a real directory

问题

I've written the codes below inside a .htaccess file.

RewriteEngine On
Options +FollowSymLinks

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^([^/\.]+)/([^/\.]+)/?$ index.php?p=$1&id=$2 [NC,QSA,L]
RewriteRule ^([^/\.]+)/?$ index.php?p=$1 [NC,QSA,L]

I have made a control panel for administrator of my website inside admin directory too. The problem is that when I want to enter to control panel from this address www.site.com/admin, it does not show what I really want. After that, URL changes to www.site.com/admin/?p=admin.
What is the problem ?

Conditions are applied on following rule only.
Your second rule is evaluated even if it is an existing directory or file.

If your 2 rules must respect both conditions, you have 2 possibilities.

Duplicate your conditions:

RewriteEngine On
Options +FollowSymLinks

# this rule is evaluated if not a directory AND not a file
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/\.]+)/([^/\.]+)/?$ index.php?p=$1&id=$2 [NC,QSA,L]

# this rule is evaluated if not a directory AND not a file
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/\.]+)/?$ index.php?p=$1 [NC,QSA,L]

Or simulate if/else condition by doing nothing if it's a directory/file

RewriteEngine On
Options +FollowSymLinks

# if file or directory, leave (do nothing)
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]

# if we reach here, means it's not a file or directory. So rules can be evaluated
RewriteRule ^([^/\.]+)/([^/\.]+)/?$ index.php?p=$1&id=$2 [NC,QSA,L]
RewriteRule ^([^/\.]+)/?$ index.php?p=$1 [NC,QSA,L]

Also, this is not so important but you don't have to escape . when into square brackets: ([^/\.]+) can be ([^/.]+)
