RE: [PEAR] DataObject: getLink

Marco, This might be a typo, but shouldn't you have "$tb_A->find();" rather than "$content->find();" and in the next line "while ($tb_A->fetch)" rather than "while ($content->fetch)"? Also, check that your links.ini file has an entry like this: [tb_C] id_A = tb_A:id_A id_B = tb_B:id_B Andy > Hello > > I have 3 tables that build together a m:n relation. > > Table tb_A has a filed (integer) called id_A > > Table tb_B has a filed (integer) called id_B > > Table tb_C has a filed (integer) called id_C and the keys from table > A (id_A) and table B (id_B) > > My (test-) code looks as follows: > > $tb_A = new DataObject_A(); > $tb_A->id_A = 5; > > $content->find(); > while ($content->fetch()) { > $c = $tb_A->getLink('id_A', 'tb_c', 'id_A'); > > $str = "id_A: " . > $tb_a->id_A . > " references in tb_C id_B: " . > $c->id_B . > "<br>"; > > echo $str; > } > > > This code does not work as expected.
