cakephp form helper（select）optgroup嵌套选项数组问题

Posted 2021-02-25

This problem occurs when there is a duplicated name for the first level item (optgroup) and a second level item (option). The rendered select will not contain the mentioned option unless you do the following...

// In the view...
 
// example array
$test = array(
    'blah' => array (0 => 'werd', 1 => 'hah'),
    'woo' => array(2 => 'yay'),
    'bla' => array(3 => 'hoo', 4 => 'ters'),
    'asdf' => array(5 => 'asdf'), // this item won't appear in the list
    'lksjldkfj' => array(6 => 'asdfasdfasdf'),   
);
 
echo $form->input('zone.id', array('options' => $zonesList, 'empty' => __('Elegí tu ciudad', true), 'class' => 'selectBox', 'showParents' => true ) ); // note the 'showParents' parameter
