Debugging

SilverStripe can be a large and complex framework to debug, but there are ways to make debugging less painful. In this guide we show the basics on defining the correct Environment Type for your application and other built-in helpers for dealing with application errors.

Environment Types

Configure your SilverStripe environment to define how your web application behaves.

Logging and Error Handling

Trap, fire and report diagnostic logs, user exceptions, warnings and errors.

URL Variable tools

Useful debugging tools you can use right in the browser

Template debugging

Track down which template rendered a piece of html

Performance

See the Profiling documentation for more information on profiling SilverStripe to track down bottle-necks and identify slow moving parts of your application chain.

Debugging Utilities

The Debug class contains a number of static utility methods for more advanced debugging.

	Debug::show($myVariable);
	// similar to print_r($myVariable) but shows it in a more useful format.

	Debug::message("Wow, that's great");
	// prints a short debugging message.

	SS_Backtrace::backtrace();
	// prints a calls-stack
