I need to limit the textarea message of the core module contact form to a certain number of characters.
Here are the facts
The Form API does not allow one to set a maxlength on textarea field types [while plain HTML does]
The Maxlength module , doesn't allow you to actually set a maximum length. It gets its max length from the field's max length, defined on each content type's manage field section
Creating a new form element type using hook_element_info, still doesn't gurantee I can add the
#maxlengthto the textarea. Besides if I succeed I need to alter again the contact form module to overrride actual message textarea field with mine.
So I can I alter it plain and straightforward?
What is the best idea to alter all textarea fields in the website?
