This plugin takes a simple concept of giving you fields to enter information that use the meta tags built into 
Wordpress and expands on it. Modifying conf.txt in the plugin directory will allow you to enter custom fields to 
the Posts pages to add textfields, textarea, dropdown selections, checkboxes, and radio selections.
On top of all this simplicity, it also integrates several popular WordPress plugins. With gallery selection for 
NextGen Gallery you can select a gallery to save the id to a meta field for your post to pull in your theme. Support 
for WordTube video selection is also added. WP-Download Manager is also supported in this initial release to get ids 
for downloads as well.
Now while that may seem enough to make this a popular plugin, there is more. Meta Extensions allows you mark the 
fields to auto add tags based on field title or content (explained in the readme). It also allows you to set up 
checkboxes to add a post to/remove from a category automatically as wanted. All from the single conf.txt file included 
with the plugin.
One of the latest features is the ability to place conf.txt in your current theme’s directory. By placing conf.txt in 
the theme directories this allows you to run the plugin with multiple themes on your site and have custom conf.txt per 
theme to only show the specific fields needed in that theme. If the file is not in the theme directory, it pulls from 
the default conf.txt in the plugin’s directory.

<h4>CONFIGURATION</h4>
Filed/Element Types: 
 textfield – HTML Form Textfield 
 textarea – HTML Form Textarea 
 checkbox – HTML Form Checkbox 
 radio – HTML Form Radio selections 
 select – HTML Form Select box 
 gallery – HTML Form Select box to choose a NextGen Gallery 
 video – HTML Form Select box to choose a Wordtube Video 
 download – HTML Form Select box to choose a WordPress Download Manager file
To specify the custom fields, edit the file conf.txt
Each entry begins with the subject inside square brackets. The second 
line specifies its type. The third line, which only applies to type 
“radio” and “select,” enumerates the available options. Each option 
has to be separated by a hash mark (#). Each entry for standard HTML 
form entities you can also include a default which tells it which to 
mark as selected or checked. You can also include the tag option which 
will tell the plugin to add the selection as a post tag automatically. 
Tags are explained further down. Checkbox also has unique entries called 
category_id and category_name. These are filled based on existing categories 
in your WordPress site. This can be used to auto add/remove the post to the 
entered category id (and it’s matching name for error checks) when used.
Ex.
[Plan] 
type = textfield 
subtitle = Enter the generic name of your plan here.
[Favorite Post] 
type = checkbox 
category_id = 4 
category_name = Project Plans
[Miles Walked] 
type = radio 
value = 0-9#10-19#20+ 
default = 0-9
[Temper Level] 
type = select 
value = High#Medium#Low
[Hidden Thought] 
type = textarea 
rows = 4 
cols = 40
[Picture Gallery] 
type = gallery 
tag = 0
[The Video] 
type = video 
tag = 0
[Attachment] 
type = download 
tag = 0
Tags can be very useful. Below is how each special type generates the 
tag for it.
Tag Design: 
 textfield – Title of the entry when filled 
 textarea – Title of the entry when filled 
 checkbox – Title of the entry when checked 
 radio – The name of the selection 
 select – The name of the selection 
 gallery – Not handled 
 video – Not handled
<h4>Useage</h4>
Once you build your conf.txt file, you are ready to start making posts 
using the custom fields. In order to call these fields you can either 
use the built in get methods for post meta, or you can use the ones that 
I have added to the metaext class to keep your code clean and know what 
is what. Below is the current list of functions you can use in your theme 
to call the meta information easily.
