==================================================

	GetField

==================================================



Gets a field or template variable for current or

specified document or its parent up to specified

number of levels until ultimate parent is reached.



Author: Grzegorz Adamiak [grad]

Version: 1.2.2 @2006-10-25 08:54:45

License: LGPL

MODx: 0.9.2.1



Uses idea of getDoc by Mark with modification from

luke.stokes



History:

# 1.2.2

- a quick fix to "Cannot redeclare function"

# 1.2.1

- reworked fetching of template variable (again ;)

  to enable output of widget

# 1.2

- reworked fetching of template variable value to

  get INHERITED value

- removed defaulting to 'pagetitle' when $field

  not found; this is due to fact that tv can have

  empty value

# 1.1.1

- fixed small bug with $parentLevel and $topid

  check; now should work as expected

# 1.1

- reworked fetching of template variable value,

  now it gets computed value instead of nominal;

  however, still not the inherited value

- changed license to LGPL

# 1.0

- first public release
