Allow Only Last Item In Cart

Установка

Upload the allow_only_last_item_in_cart plugin to your plugin directory, activate it

For backwards compatibility, if this section is missing, the full length of the short description will be used, and
Markdown parsed.

e.g.

1. Upload allow_only_last_item_in_cart.php to the /wp-content/plugins/ directory
2. Activate the plugin through the ‘Plugins’ menu in WordPress
3. Place <?php do_action('allow_only_last_item_in_cart'); ?> in your templates

A few notes about the sections above:

• «Contributors» is a comma separated list of wordpress.org usernames
• «Tags» is a comma separated list of tags that apply to the plugin
• «Requires at least» is the lowest version that the plugin will work on
• «Tested up to» is the highest version that you’ve successfully used to test the plugin. Note that it might work on
  higher versions… this is just the highest one you’ve verified.

• Stable tag should indicate the Subversion «tag» of the latest stable version, or «trunk,» if you use /trunk/ for
  stable.

  Note that the readme.txt of the stable tag is the one that is considered the defining one for the plugin, so
  if the /trunk/readme.txt file says that the stable tag is 4.3, then it is /tags/4.3/readme.txt that’ll be used
  for displaying information about the plugin. In this situation, the only thing considered from the trunk readme.txt
  is the stable tag pointer. Thus, if you develop in trunk, you can update the trunk readme.txt to reflect changes in
  your in-development version, without having that information incorrectly disclosed about the current stable version
  that lacks those changes — as long as the trunk’s readme.txt points to the correct stable tag.

  If no stable tag is provided, it is assumed that trunk is stable, but you should specify «trunk» if that’s where
  you put the stable version, in order to eliminate any doubt.
