5.5.7. Other features and tricks
- Closing tags can also have attributes. OPT does not require non-attribute tags in this place, so you can handle them, like in any other tag type.
- In order to make some PHP code "dynamic" (in sense of the output caching),
call the $this->compiler->dynamic() method and pass the
new state as a parameter (true - begins the dynamic code). But notice that
this method is also used by the {dynamic} instruction.
If you do not want to create conflicts, always check the state in this
instruction's processor ($this->compiler->processors['dynamic']->active).
- In order to generate a compiler error, call the
$this->tpl->error() method. It takes three parameters:
the error type (E_USER_ERROR or E_USER_WARNING),
the error description and the error code. For user extensions, the codes from 401 are reserved.
- The instructions can control, whether they can be executed in master templates,
or not. Define the protected class variable $inMaster set to
true in order to allow the use in the master template. While processing, you can always
check the current state by the $this -> compiler -> master. True means
the master template is being processed.
