Concepts

CMS

WordPress is a blogging tool and content management system (CMS).

WordPress separates the content, structure and style.

WordPress is generally used to host a Blog. A Blog is short for web log, and is kind of a journal.

Posts and Pages

An article written for a blog is called a post. Posts are stored linear, organized by date/subject/category/tags. Tags organize posts by specific subject, and categories ore more generic.

More static articles are called pages. Pages are stored hierarchically (parent/child).

Remember: pages are for standalone content, and posts are for blog articles.

Posts and pages can be edited with the Visual Editor, or HTML text editor.

The 'front page' is the first page people will see.

Tags and Categories

Tags organize posts by specific subject, and categories ore more generic.

"A post can live in more than one category and tag, but generally speaking posts usually have more tags than categories, since categories are broad subjects and tags are narrower. This isn’t a rule so much as a convention."

Appearance and Themes

Styles are managed through themes. This is where the CSS is kept.

Themes control the look of the site, and plugins add new functionality. Widgets are a special kind of plugin that goes into areas defined by a theme.

Full Theme CSS (and PHP code) can be modified through Dashboard -> Appearance -> Editor.

Plugins

Plugins add new functionality. Widgets are a special kind of plugin that goes into areas defined by a theme.

Example plugins: caching (for performance), adding credit card processing, SEO related, etc

"A shortcode is a type of code that you can copy and paste into an area of your site that automatically references a plugin, widget, or theme element."

"Widgets are a type of plugin that you can insert into your site to add a specific extra feature. Widgets tend to perform limited functions and can be slotted into only certain spots on a web page."

Dashboard

Content can be managed and organized through the Dashboard.

Photos

Photos can be managed with the Media Library. The Media Library is private.

"A featured image is often a panorama-style image that lives at the top of the page or post or a thumbnail image that lives next to the post. This can make your blog look quite appealing."

Menus

Menus can be placed in areas marked Theme Locations on a theme. Pages can be manually or automatically added to a menu.

Tagline

A slogan or one-sentence description of your site

WordPress is built on PHP and MySQL.

Themes I have used:

Pretty URLs with Permalinks

"By default WordPress uses web URLs which have question marks and lots of numbers in them; however, WordPress offers you the ability to create a custom URL structure for your permalinks and archives. This can improve the aesthetics, usability, and forward-compatibility of your links. A number of tags are available, and here are some examples to get you started."

Permalinks are important for SEO and human readability.

Permalinks will change your URLs from this http://example.com/?p=123 to this http://example.com/sample-post/.

Doc: http://codex.wordpress.org/Using_Permalinks

Admin URL: http://example.com/wp-admin/options-permalink.php

Customization

Disable Comments

Settings >> Discussion >> uncheck "Allow people to post comments on new articles"

This applies to new posts that you will publish from now on. To disallow comments from already publish posts:

Posts >> select them all and "Edit" under bulk actions and hit apply >> choose "do not allow" next to comments and hit update posts.

Add Posts to Menu

"All you have to do is click "Screen Options" while viewing the "Custom Menu" manager and place a check beside "Posts" to show the elusive hidden "Posts" widget. Now you can add "Posts" to your custom menus" [1]

Plugins

Embed Widgets in Pages

Embed Widgets in Pages or Posts:

  1. Install and activate amr shortcode any widget plugin
  2. Add Widget to Shortcodes Sidebard (Appearance >> Widgets)
  3. Add shortcode tag within Page or Post
[do_widget calendar]
[do_widget "recent posts"]
[do_widget id=sticky-posts-2]

I find the "id=" to work the best, but hardest to find.

To debug:

"enter some garbage in the shortcode [do_widget wtf] and the plugin will offer you a try debug (if you are admin and logged in that is) Click on the "try debug""

or

"add ?do_widget_debug=1 to the url of the page that contains the [do_widget] shortcode."
