I can’t tell exactly what you are asking but this comment…
What I did recently is that I created a wordpress dir on FTP server
and move stuff there, but now people would have to input
mydomain.com/wordpress to access my webpage…
… makes me wonder it you don’t have a subdirectory install. If that is the case, you need to follow the instructions in the Codex to get this working.
- Go to the General panel.
- In the box for Site address (URL): change the address
to the root directory’s URL. Example: http://example.com- Click Save Changes. (Do not worry about the error
message and do not try to see your blog at this point! You will
probably get a message about file not found.)- Copy (NOT
MOVE!) the index.php and .htaccess files from the
WordPress (wordpress in our example) directory into the root
directory of your site—the latter is probably named something like
www or public_html. The .htaccess file is
invisible, so you may have to set your FTP client to show hidden files. If you are
not using pretty permalinks, then you may not have
a .htaccess file. If you are running WordPress on a
Windows (IIS) server and are using pretty permalinks, you’ll have
a web.config rather than a .htaccess file in your
WordPress directory.- Edit your root directory’s
index.php.
- Open your root directory’s
index.php file in a text editor- Change the line that
says:
require(‘./wp-blog-header.php’);
to the
following, using your directory name for the WordPress core
files:
require(‘./wordpress/wp-blog-header.php’);- Save the file.
- Login to your site (if
you aren’t still already). The URL should still be
http://example.com/wordpress/wp-admin/- If you have
set up Permalinks, go to the Permalinks panel and update your Permalink
structure. WordPress will automatically update your .htaccess
file if it has the appropriate file permissions. If WordPress can’t
write to your .htaccess file, it will display the new rewrite
rules to you, which you should manually copy into your
.htaccess file (in the same directory as the main
index.php file.)
