为 symfony 选择字段设置默认数据,将 multiple 设置为 true
set default data for symfony choice field with multiple set to true
我正在尝试呈现一个带有复选框的选择字段,我希望在编辑模式下,这具有用户之前检查过的数据,这意味着一种设置默认数据的方式。下面的代码不起作用。有人可以帮忙吗?谢谢
$days = array("monday" => "monday","tuesday" => "tuesday");
$builder->add('channels', 'choice', array(
'choices' => array(
'days' => $days,
),
'multiple' => true,
'expanded' => true,
'required' => true,
'data' => array("choices" => array("days" => array("monday")))
));
删除数据数组中的choices
键:
$builder->add(
'channels',
'choice',
array(
...
'data' => array("monday")
)
);
我认为这应该可行:
$builder->add(
'channels',
'choice',
array(
...
'data' => array("monday"),
)
)
这个对我有用(Symfony 2.3.x):
$days = array("monday" => "Monday","tuesday" => "Tuesday","wednesday" => "wednesday","thursday" => "thursday");
$builder->add('channels', 'choice', array(
'choices' => array(
'days' => $days,
),
'multiple' => true,
'expanded' => true,
'required' => true,
'data' => array("wednesday","thursday","tuesday")
));
注意:使用键索引设置数据而不是值。 "Tuesday" 不会像 "tuesday" 那样在这里工作。
