Change URL on Wordpress - php

Question

I have been working on a WordPress site.
www.example.com and the main homepage of my site(index.html) says "We're under construction etc." and it's just an image.
For the development of the website, I have been using a different directory - www.example.com/dev and everything I have developed has been under /dev(/dev/index.php etc.)
The website is now ready and I need to point the finsihed website (www.example.com/dev) to the actual public site(which is now under www.example.com) that I have finished. How do I go about this?

Answer 1

use this code for changing you website url
SET #oldsite='http://www.example.com/dev';
SET #newsite='http://www.example.com';
UPDATE wp_options SET option_value = replace(option_value, #oldsite, #newsite) WHERE option_name = 'home' OR option_name = 'siteurl';
UPDATE wp_posts SET post_content = replace(post_content, #oldsite, #newsite);
UPDATE wp_links SET link_url = replace(link_url, #oldsite, #newsite);
UPDATE wp_postmeta SET meta_value = replace(meta_value, #oldsite, #newsite);

Answer 2

This can be done 2 ways,
You can do this easily by changing site_url in options table. Once you transfer data and change the url your site should be running on the new url. If you have stored static urls in post or pages then, you have to change that as well.
Export sql file from phpmyadmin. Now find and replace all urls from old to new ones.
Note: Keep your current development site working as, sometimes it's possible that contact form 7 or any data gets missing. For example, Widgets get in inactive mode sometime.
Once your new website is confirmed then you can remove your old website.

Answer 3

step 1:
Just copy your all files and folder from www.example.com/dev to www.example.com
step 2:
open your database and in table wp_option
siteurl
http:// www.example.com/dev to www.example.com/
home
http:// www.example.com/dev to www.example.com/

Moving Directories On Your Existing Server
Wordpress has a wiki page that explained this for you:
Moving Wordpress
Here are the step-by-step instructions to move your WordPress site to a new location on the same server:
Create the new location using one of these two options:
If you will be moving your WordPress core files to a new directory,
create the new directory.
If you want to move WordPress to your root directory, make sure all
index.php, .htaccess, and other files that might be copied over are
backed up and/or moved, and that the root directory is ready for the
new WordPress files.
Log in to your site.
Go to the Administration > Settings > General panel.
In the box for WordPress Address (URL): change the address to the
new location of your main WordPress core files.
In the box for Site Address (URL): change the address to the new
location, which should match the WordPress (your public site)
address.
Click Save Changes.
(Do not try to open/view your site now!)
Move your WordPress core files to the new location. This includes
the files found within the original directory, such as
http://example.com/wordpress, and all the sub-directories, to the
new location.
Now, try to open your site by going to yourdomain.com/wp-admin.
Note, you may need to go to yourdomain.com/wp-login.php
If you are using Permalinks, go to the Administration > Settings > Permalinks
panel and update your Permalink structure to your
.htaccess file, which should be in the same directory as the main
index.php file.
Existing image/media links uploaded media will refer to the old
folder and must be updated with the new location. You can do this
with the Better Search Replace plugin, WP-CLI's search-replace if
your hosting provider (or you) have installed WP-CLI, manually in
your SQL database, or by using the 3rd party database updating tool
Search and Replace Databases Script * Note: this script is best used
by experienced developers.
In some cases your permissions may have changed, depending on your
ISP. Watch for any files with 0000 permissions and change them
back to 0644.
If your theme supports menus, links to your home page may still have
the old subdirectory embedded in them. Go to Appearance > Menus and
update them.
Sometimes you would need to restart your server,
otherwise your server may give out an error. (happens in MAMP
software (Mac)).
It is important that you set the URI locations BEFORE you move the
files.
If You Forget to Change the Locations
If you accidentally moved the files before you changed the URIs: you have two options.
Suppose the files were originally in /path/to/old/ and you moved them to /path/to/new before changing the URIs. The way to fix this would be to make /path/to/old/ a symlink (for Windows users, "symlink" is equivalent to "shortcut") to /path/to/new/, i.e.
ln -s /path/to/new /path/to/old
and then follow the steps above as normal. Afterwards, delete the symlink if you want.
If you forget to change the WordPress Address and Blog Address, you will be unable to change it using the wordpress interface. However, you can fix it if you have access to the database. Go to the database of your site and find the wp_options table. This table stores all the options that you can set in the interface. The WordPress Address and Blog Address are stored as siteurl and home (the option_name field). All you have to do is change the option_value field to the correct URL for the records with option_name=’siteurl‘ or option_name=’home‘.
