For each system activity a various number of functions can be defined.
Each of these functions needs a unique ID, a name and a definition. Functions are defined in the XML configuration underneath the functions element. For the function CSV export we need the following code:
Function definition
...
<functions>
<function id='exportCsv' name='CONST_SA_CSV_CSVEXPORT_NAME' description='CONST_SA_CSV_CSVEXPORT_DESCRIPTION'>
...
</function>
</functions>
...
When you configure functions, you can also define language constants inside the language files. The language file "english.php" looks like this:
Contents of the language file english.php
<?php
define('CONST_SA_CSV_NAME', 'CSV Export');
define('CONST_SA_CSV_DESCRIPTION', 'This system activity can be used to export data from a subtable into a CSV file.');
define('CONST_SA_CSV', 'CSV');
define('CONST_SA_CSV_CSVEXPORT_NAME', 'Export data into a CSV');
define('CONST_SA_CSV_CSVEXPORT_DESCRIPTION', 'Data will be exported from a subtable into a CSV file.');
