I am creating a Wordpress Recent Posts widget for practice. However I have run into a few things that I just don't know how to do. First of all the widget has to display the date and time of the post, the posts title, text with a smart cut off character limit and a read more link. It also has to allow the admin to specify the title, the category, the number of posts to display, number of characters to display on the post, and lastly change the wording of the 'read more' link.
I have already created the widget and figured out how to do everything but make the category selection a drop down selection with the categories already in there (right now it is just a text block for the admin that you can type in which category to display), how to limit characters in the_excerpt
while making it so it smartly cuts off at the end of a word and allowing admin to specify how my characters are allowed, and how to create a read more link while allowing admin to specify what it says.
I will post the code I have so far below along with a link to the site that contains the widget in the sidebar. I am new to Wordpress Widget design so help would be greatly appreciated.
