Simple Coldfusion Error Catching
Jan 31, 2007
This should work on CF7: It's quite generic, but essential. With the example below, add these two functions to your application.cfc and create a template to use for when the error is thrown. This example sends you an email with a dump of all the necessary vars used to troubleshoot.
You could of course use CFFILE to write a line to an html file instead of mailing. Also, dependent on your hosting, some shared hosts may restrict the dumpling of cgi vars ( you'll get a sandbox.security error instead).
Add this to your application.cfc
