Classe: TErrorHandler  - X-Ref

TErrorHandler class

TErrorHandler handles all PHP user errors and exceptions generated during
servicing user requests. It displays these errors using different templates
and if possible, using languages preferred by the client user.
Note, PHP parsing errors cannot be caught and handled by TErrorHandler.

The templates used to format the error output are stored under System.Exceptions.
You may choose to use your own templates, should you not like the templates
provided by Prado. Simply set {@link setErrorTemplatePath ErrorTemplatePath}
to the path (in namespace format) storing your own templates.

There are two sets of templates, one for errors to be displayed to client users
(called external errors), one for errors to be displayed to system developers
(called internal errors). The template file name for the former is
<b>error[StatusCode][-LanguageCode].html</b>, and for the latter it is
<b>exception[-LanguageCode].html</b>, where StatusCode refers to response status
code (e.g. 404, 500) specified when {@link THttpException} is thrown,
and LanguageCode is the client user preferred language code (e.g. en, zh, de).
The templates <b>error.html</b> and <b>exception.html</b> are default ones
that are used if no other appropriate templates are available.
Note, these templates are not Prado control templates. They are simply
html files with keywords (e.g. %%ErrorMessage%%, %%Version%%)
to be replaced with the corresponding information.

By default, TErrorHandler is registered with {@link TApplication} as the
error handler module. It can be accessed via {@link TApplication::getErrorHandler()}.
You seldom need to deal with the error handler directly. It is mainly used
by the application object to handle errors.

TErrorHandler may be configured in application configuration file as follows
<module id="error" class="TErrorHandler" ErrorTemplatePath="System.Exceptions" />
