database access from dca\tl_module.php possible?

[lumo]

when i try to access the database using

$q1 = $this->Database->prepare($sql)->execute();

it ends in an error

Fatal error: Using $this when not in object context in C:\...\mymodule\dca\tl_module.php on line 67

The DCA files are mostly configuration files, they cannot have executable PHP code within them since an object reference such as $this will have no context.

Instead you can create class files within the file ( ie class myclass extends Backend{}) and then use the various callback arguments to call the relevant class.
