custom field keys, allowing post- and page-specific meta content in your sidebar. This plugin started life as a plaintxt.org experiment for WordPress by Scott Wallick, but I needed (or wanted) it to do more, so I've created this version which has more functionality than the original. For some detailed instructions about it's use, check out my wiki.

------------------------------------------------------------------------------------------------------------
Version History:-
Version Date Author Description
======= ========= ====================== ======================================
0.81 31-Jul-09 Christina Louise Warne FIXED - When using widget index field, widgets that didn't have
data for their index were displaying the first item from the
list
0.8 17-Jul-09 Christina Louise Warne ADDED - Widget index field. This field allows you to have multiple
widgets on the page all linked to the same field (in that case,
only the widget with index 1 will display, even if the content
randomiser is selected, widgets with indexes other than 1 will
be blocked if there is no multiple linkto field specified. To
use the indexed widgets, all you do is specify the primary key
field as you do normally (lets say we have the field AMAZON).
Then on the page where you want the multiple widgets, you would
specify AMAZON-linkto=x|y|z where x,y and z are the page IDs of
the source posts
ADDED - Additional data fields 2 to 5
ADDED - $pagetitle for use in content generator. Contains title
of the source post
FIXED - In some cases, the content generator was leaving slashes in
the strings. I believe it is no longer necessary to 'escape'
strings in the custom fields or the content generator as I
think it's all handled
------- --------- ---------------------- --------------------------------------
0.7 26-Jun-09 Christina Louise Warne ADDED - Additional data field 1. This field does nothing except
get loaded from the specified custom field, if it exists. It
is primarily for use in the content generator. This ones for
you Bill.
------- --------- ---------------------- --------------------------------------
0.6 27-Mar-09 Christina Louise Warne ADDED - Widget 'Content Generator'. This field allows complex
content to be generated with PHP. Essentially the content is
eval'd and the result is dumped into the space where the field
content would normally go.
------- --------- ---------------------- --------------------------------------
0.5 02-Mar-09 Christina Louise Warne FIX - Fixed issue where some widgets were breaking the widget
More specifically, if a widget modified the $post variable,
ACFW would display (or not) data relating to the post left
in the $post variable. A fix has been implemented whereby
this widget re-initialises the main wp_query used by the main
loop and then reinitialises $post with the result
------- --------- ---------------------- --------------------------------------
0.4 10-Feb-09 Christina Louise Warne FIX - Removal of options now only occurs when the plugin is uninstalled (via uninstall.php)
FIX - Fixed text domain to acf_widget
------- --------- ---------------------- --------------------------------------
0.3 23-Dec-08 Christina Louise Warne ADDED - Add custom field '-linkto' and specify a page ID to
have the current page load the specified cfield content from the
specified page. This takes priority over acfw-linkto.
------- --------- ---------------------- --------------------------------------
0.2 05-Dec-08 Christina Louise Warne FIX - Widget was not displaying content for pages (only posts)
ADDED - Add custom field 'acfw-linkto' and specify a page ID to
have the current page load it's fields from the specified page
