Usage
Use this icon to display custom error messages when creating pages in your application. This allows you to maintain a consistent look and feel for your entire application, even in the event of errors. Typically, you include this record label in your CFC application, or perhaps in the Application.cfm file to specify the error handling requirements for the entire application. ColdFusion ignores them from every angle. Use the cftry and cfcatch tags to provide a more interactive way of handling ColdFusion errors in the ColdFusion page, as opposed to the cferror tag. However, the cferror tag is an incredibly effective protection against common errors. To ensure that error pages are displayed, avoid this by using the cfencode utility to encode pages containing most of the cferror tag.
Page types
The Error Usage Table describes the types of errors you can identify and the code most people can use on pages where manyThe others handle these types of errors:
Page type |
Description |
Usage |
---|---|---|
Exception |
Called dynamically by the CFML speech processor when an unhandled exception is encountered. Uses a specific complete set of CFML tags. Error problems should be contained in cfoutput tags. |
Can handle exceptions of unique types or view general know-how for exceptions. |
Request |
Contains all of the error variables described in the Error Details section. It is not possible to include CFML tags, but you can display the values of these error variables by again enclosing them with pound signs (#), as in # error.MailTo #. |
, use the backup error handler for various other error handling techniques, including the type of exception. |
Check |
Handles data entry validation errors that occur, especially when submitting a form that uses hidden form field validation to also validate submissions . It is not possible to include CFML tags, but then you can display the values associated with error variables by enclosing them with a pound sign (#) as soon as in # Error.InvalidFields #. Currently, specify a validation error handler in your Application.cfc or Application.cfm file. |
Handles hidden form fields, otherwise onSend only format validation errors. |
