Trap MergeBlock Error

How do we handle a MergeBlock Error that occurs when a connection to the database cannot be made. For example, I intentionally caused the connection to fail to see what MergeBlock does when no database connection is made. I get the error as follows:

TinyButStrong Error when merging block [Array]: the specified source is set to FALSE. Maybe your connection has failed.

Obviously, I do not want that to display to the end user, nor do I want the block of html related to MergeBlock to show. How do we trap such errors and prevent the html section related to the MergeBlock fields to not show.

Hi Anthony,

You can do something like this :

Or less readable but smarter:

Thanks for the help. Sometimes I get a little lost wading through the manual, and at times don't quite get a handle on the explanations. I've been programming with PHP for sometime but only recently became aware of TBS. I appreciate the effort that has gone into making it and the great help it is in designing cleaner web sites.

Well, back to MergeBlock errors and perhaps this question has been asked and answered before but after looking through the forum and manual, I don't seem to be coming up with a solution. The above solved the connection error situations, but what can I do to trap errors that are sent back by the sql connection. For example, when I get something like this:

TinyButStrong Error when merging block [eventsblock]: PostgreSQL error message when opening the query: ERROR: pg_atoi: error in "all": can't parse "all"

Obviously, I do not want that show in the browser, although I would want my code to trap that error and log it. How do we handle these errors with TBS. Using $TBS->NoErr = true suppresses the error message but the template fields output to the browser. Therefore, I need to trap the error, log it, and prevent browser from showing any merge field templates.
