[TYPO3-dev] sorting of DAM assets in mm-table

[Thomas Mammitzsch]

hi list,

i try to make assets sortable within a category. I think that should be 
done within the category tceform of dam_catedit (showing all assets in 
that category within a single multiselect field with sort buttons, like 
the original tca type select).

i think the "sorting_foreign" column in the "tx_dam_mm_cat" is provided 
for that, although there is no such functionality in dam yet.

Unfortunately i don't have any idea how to write the sorting (once that 
custom select field is ready) to that "sorting_foreign"-column in the 
mm-table.
At the moment i have added a new field to tx_dam_cat in TCA to get the 
preselection of assets in the category i'm editing.

'membersorting' => array(
	'exclude' => '1',
	'label' => 'membersorting',
	'config' => array(
		'type' => 'select',
		'foreign_table' => 'tx_dam',
		//'itemsProcFunc' => 'user_dam_sorting->main',
		'size' => 10,
		'maxitems' => 20,
		'MM' => 'tx_dam_mm_cat',
		'MM_opposite_field' => 'uid',
		'MM_table_where' => 'AND tx_dam_mm_cat.uid_foreign=7',
	)
),

As you can see i tried an itemsProcFunc which is working well for 
preselecting records by category. The "MM" config settings didn't work 
for me for a preselection. Is there a predefined method to fill a 
sorting_foreign-column i can use?
