[TYPO3-dev] Bidirectional MM relations

[Tomi Hrovatin]

Hi,

it works now. Thnx.

If somebody needs this, here is the solution for using one bidirectional 
MM table (for all relations with companies) and type='select':

TCA for companies (local table):
"employees" => Array (
	'label' => 'LLL:EXT:ext_name/locallang_db.xml:employees',
	'config' => array (
		'type' => 'select',
                 'size' => 3,
                 'autoSizeMax' => 30,
                 'minitems' => 3,
                 'maxitems' => 10,
                 'foreign_table' => 'tx_employees',
		"MM" => 'tx_companies_mm_ref',
		"MM_match_fields" => Array(
			"tablenames" => 'tx_employees'
		),				
	),
)

TCA for employees (foreign table):
"companies" => Array (
	'label' => 'LLL:EXT:ext_name/locallang_db.xml:companies',
	'config' => array (
		'type' => 'select',
                 'size' => 3,
                 'autoSizeMax' => 30,
                 'minitems' => 3,
                 'maxitems' => 10,
                 'foreign_table' => 'tx_companies',
		"MM" => 'tx_companies_mm_ref',
		"MM_foreign_select" => 1,
		"MM_opposite_field" => 'employees',
		"MM_match_fields" => Array(
			"tablenames" => 'tx_employees'
		),				
	),
)
