[TYPO3-dam] Sorting of items in list view (and frontend)

[axel at zwo-null.de]

Hi Frank,

	i didn't connect to the author, since i already made some updates
and contacted
	the author concerning the problems with field length in the DAM and
got no response

	The changes are the following:

	Place the following source line in class.tx_dam_actionsRecord.php
after the class: tx_dam_action_lockWarningRec

/***************************************************************************

/**

	/**

	 *

	 * @param	array		$itemInfo Item info array. Eg

	function isValid ($type, $itemInfo=NULL, $env=NULL) {

		}
		if($valid)
		{
			$valid = isset($itemInfo['prevSorting']);
		};
		return $valid;
	}

	This will add the appropriate actions to the control.

	Then add this actions to the ext_tables.php file. To get the order
of the buttons like the 
	file menu you should place this lines 
	
		tx_dam::register_action ('tx_dam_action_moveUpRec',
'EXT:dam/components/class.tx_dam_actionsRecord.php:&tx_dam_action_moveUpRec'
);
		tx_dam::register_action ('tx_dam_action_moveDownRec',
'EXT:dam/components/class.tx_dam_actionsRecord.php:&tx_dam_action_moveDownRe
c');
	
	before 

		tx_dam::register_action ('tx_dam_action_hideRec',
'EXT:dam/components/class.tx_dam_actionsRecord.php:&tx_dam_action_hideRec');



	Finally the most importend point is to update the way the DAM
delivers records for listing in class.tx_dam_listrecords.php

	Look for the following lines in function renderList:

		$this->currentTable['prev'][$row['uid']] = $prevPrevUid;
		$this->currentTable['next'][$prevUid] = '-'.$row['uid'];
		$this->currentTable['prevUid'][$row['uid']] = $prevUid;

	And append 

		$accRows[$row['uid']]['prev'] 		= $prevPrevUid;
		$accRows[$prevUid]['next'] 			=
'-'.$row['uid'];

	right after this lines. That will store the previous and next item
in the row delivered to
	the actions .. so the chain is closed :o)

	I can also send the full files if required to the persons
interested.

Hope that helps,
Axel
