Generating URLs in custom fields

[redjen]

We maintain a database of bugs, some of which we then report into to our application vendor's bug database. I'm currently using a custom field for the vendor's issue number. The vendor's bug tracking system is similar to Mantis in that specific issue pages can be reached by supplying the issue number in the URL query string (i.e. http://example.com/bug.asp?ticket_id=1234).

I would like to have a custom field in Mantis that generates a hyperlink based on the ticket number the user enters. For example:

1. User enters the vendors number into the "vendor issue number" custom field in a ticket's info.

2. When viewed, the "vendor issue number" field displays the vendor's issue number. The issue number is a link pointing to the ticket in the vendor's database.

Is there anything in Mantis that would allow me to implement something like this? Or do I need to delve into developing my own type of custom field? Please let me know if my explanation of what I want is not clear.

Thanks,
