Extension: Non-unique URL titles

The attached add-on files may be out of date. Please visit Devot-ee for the latest versions.

URL titles of entries should be unique for each weblog.

If an entry having non-unique URL title is submitted, ExpressionEngine attaches a number symbol to the end of URL title.

This behavior is quite sensible in most cases. The problem arises when original non-unique URL title ends with a number. For example, if original non-unique URL title was “article_2”, then after appending additional number it will be “article_21” or “article_22”, which might be confusing for both content publishers and users.

This extension makes it possible 1) to specify that there should be a separator (or no separator) between original non-unique URL title and a string which is added by ExpressionEngine to ensure uniqueness; 2) to specify that a string which is added by ExpressionEngine to ensure uniqueness of URL title should be non-numeric or numeric.
