NP_CropExtended

This plugin crop extended body after x number of words.

This plugin shows a cropped “extended body” in a nucleus page. This can be usefull when you want to show an excerpt of the extended_body of an article and dont want alter/rewrite the structure of your articles. The plugin creates a new template variable called <%CropExtended%> that cut the extended body after the number of words that you can specify in the plugin options. The script needs a lot of improvements to correctly works (eg: in the current version HTML tag will be truncated…).

The code is based on admun's plugin NP_AutoExtended.

• Copy and paste the code below into a file called NP_CropExtended.php (or download it from my site).
• Upload the file into the nucleus plugin directory,
• Then install or update the subscription list.
• Include <%CropExtended%> in your template where you want the output to appear.

/*
************************************************
Use <%CropExtended%> in a template to show a
little portion of the extended part of an
article in a page. Use plugin option to set how
many words show in the extended cropped part.
