Export_Plugins

Needed functions

There are several standard functions that must be included in each export plugin:

• get_file_content_type()
• get_file_extension()
• get_display_name()
• get_plugin_type() - Return 'row' or 'item'
• Optional: file_header($title)
• Optional: file_footer()
• Optional: http_header($filename, $content_type)
  If this method exists, it is assumed that it will provide the required header(...) calls to stream the headers out to the browser. You can also implement a dummy version of this function if you want to dump the whole content as part of the close() method.

Depending on the plugin_type, there are extra methods required.

• Row based:
  • item_row($columns)
  • Optional: prompt_header($columns)
  • Optional: data_header($columns)
  • Optional: close()
• Item based:
  • start_item($item_id, $s_item_type, $title)
  • end_item($item_id)
  • start_item_instance($instance_no, $owner_id, $borrow_duration, $s_status_type, $status_comment)
  • end_item_instance()
  • item_attribute($item_id, $s_attribute_type, $order_no, $attribute_val)
