Using themes in WordPress…………

What is a Theme?

Fundamentally, the WordPress Theme system is a way to “skin” your weblog. Yet, it is more than just a “skin.” Skinning your site implies that only the design is changed. WordPress Themes can provide much more control over the look and presentation of the material on your website.

A WordPress Theme is a collection of files that work together to produce a graphical interface with an underlying unifying design for a weblog. These files are called template files. A Theme modifies the way the site is displayed, without modifying the underlying software. Themes may include customized template files, image files (*.jpg, *.gif), style sheets (*.css), custom Pages, as well as any necessary code files (*.php). For an introduction to template files, see Stepping Into Templates.

Let’s say you write a lot about cheese and gadgets. Through the use of the WordPress Loop and template files, you can customize your Cheese category posts to look different from your Gadgets category posts. With this powerful control over what different pages and categories look like on your site, you are limited only by your imagination. For information on how to use different Themes for different categories or posts, see The Loop in Action and Category Templates.
Get New Themes

The WordPress Theme Directory is the official site for WordPress Themes which have been checked and inspected, and are free for downloading. The site features the ability to search by type and style, and offers a demonstration of the page view elements of the Theme.
Using Themes

WordPress supplies two Themes in its distribution for your initial use. You can switch between these two Themes using the admin panel. Themes that you add to that directory will appear in the Administration Panels > Design > Themes as additional selections.
Adding New Themes
Appearance Panel

There are many Themes available for download that will work with your WordPress installation.

If the Theme that you are installing provides instructions, be sure to read through and follow those instructions for the successful installation of the Theme. It is recommended that Theme developers provide installation instructions for their own Themes, because Themes can provide special optional functionality that may require more steps than the basic installation steps covered here. If your Theme does not work after following any provided instructions, please contact the Theme author for help.

To add a new Theme to your WordPress installation, follow these basic steps:

1. Download the Theme archive and extract the files it contains. You may need to preserve the directory structure in the archive when extracting these files. Follow the guidelines provided by your Theme author.
2. Using an FTP client to access your host web server, create a directory to contain your Theme in the wp-content/themes directory provided by WordPress. For example, a Theme named Test should be in wp-content/themes/test. Your Theme may provide this directory as part of the archive.
3. Upload the Theme files to the new directory on your host server.
4. Follow the instructions below for selecting the new Theme.

Adding New Themes using cPanel

If your host offers the cPanel control panel, and the Theme files are in a .zip or .gz archive follow these instructions. Note: This assumes the Theme you download is a compressed (zip) file and the files in the zip file are in their ‘named’ folder.

1. Download the Theme zip file to your local machine.
2. In cPanel File Manager, navigate to your Themes folder. If you have WordPress installed in it’s own folder called wordpress, you would navigate to “public_html/wordpress/wp-content/themes” and if WordPress is installed in your web-root folder you would navigate to “public_html/wp-content/themes”.
3. Once you’ve navigated to the Themes folder in cPanel File Manager, click on Upload file(s) and upload that zip file you saved in Step 1.
4. Once the zip file is uploaded, click on the zip file name in cPanel, then in the panel to the right, click on Extract File Contents, and that zip file will be uncompressed.
5. Follow the instructions below for selecting the new Theme.

Adding New Themes using the Administration Panel

You can download Themes directly to your blog by using the Add New Themes option in the Appearance sub-menu.

1. Log in to the WordPress Administration Panel.
2. Select the Appearance panel, then Themes.
3. Select Install Themes
4. Use the sub-menu or the Search or Filter options to locate a Theme you would like to use.
5. Click on the Preview link to preview the Theme or the Install link to upload the Theme to your blog.
6. Use the Upload link in the top sub-menu to upload a zipped copy of a Theme that you have previously downloaded to your machine.

Selecting the Active Theme

To select a Theme for your site:

1. Log in to the WordPress Administration Panel.
2. Select the Appearance panel, then Themes.
3. From the Available Themes section, click on the Theme title (or Theme screenshot) for the Theme you wish to activate.
4. A preview of the Theme will be shown.
5. To activate the Theme click the Activate “Theme Name” link in the top right.

Your selection should immediately become active.

Note: If the Theme preview is blank, do not activate the new Theme without investigating further. Your site may not be displayed correctly, otherwise.

Famous 5-Minute Install

Here's the quick version of the instructions, for those that are already comfortable with performing such installations. More detailed instructions follow.

If you are not comfortable with renaming files, Steps 3 and 4 are optional and you can skip them as the install program will create wp-config.php file.

Download and unzip the WordPress package if you haven't already.
Create a database for WordPress on your web server, as well as a MySQL user who has all privileges for accessing and modifying it.
Rename the wp-config-sample.php file to wp-config.php.
Open wp-config.php in a text editor and fill in your database details as explained in Editing wp-config.php to generate and use your secret key password.
Upload the WordPress files in the desired location on your web server:
If you want to integrate WordPress into the root of your domain (e.g. http://example.com/), move or upload all contents of the unzipped WordPress directory (but excluding the directory itself) into the root directory of your web server.
If you want to have your WordPress installation in its own subdirectory on your web site (e.g. http://example.com/blog/), create the blog directory on your server and upload WordPress to the directory via FTP.
Run the WordPress installation script by accessing wp-admin/install.php in a web browser.
If you installed WordPress in the root directory, you should visit: http://example.com/wp-admin/install.php
If you installed WordPress in its own subdirectory called blog, for example, you should visit: http://example.com/blog/wp-admin/install.php

That's it! WordPress should now be installed.
