How to set limits on line length when formatted text is entered into profile form?
Using Jamroom
The jrCore_format_string is a function that takes text from any form field, editor or textarea type, and formats it according to what you have set in your ACP > Core > System Core > Quota Config > Active Text Formatters.
If you want to limit the number of characters shown from an editor or textarea field, then you may want to use the Smarty truncate variable modifier.
