Setting the target to the iframe is putting a target='iframe_name' in your links. Does the setTarget you use exist? Since this is 1.3.3 I can't really test it x.x But in 1.3.4, instead of using the Link object I used HTML in a Comment object. Not sure if this would work in 1.3.3
PHP Code:
for($row = 0; $row < $daycare->getTotalRows(); $row++){
$daycareRow = new TRow("row{$row}");
for($column = 0; $column < $daycare->getTotalColumns(); $column++){
$adopt = new OwnedAdoptable($adopts[$index]);
$cell = new ArrayList;
$cell->add(new Comment("<a href='/levelup/click/{$adopt->getAdoptID()}' target='iframe'><img src='{$adopt->getImage()}'></a>"));
$cell->add(new Comment($daycare->getStats($adopt)));
$daycareCell = new TCell($cell, "cell{$index}");
$daycareCell->setAlign(new Align("center", "center"));
$daycareRow->add($daycareCell);
$index++;
if($index == $total) break;
}
$daycareTable->add($daycareRow);
}
$document->add($daycareTable);
$document->add(new Comment("<iframe name='iframe' src=''></iframe>"));
