CakePHP 2.0选择表格多个选择 [英] CakePHP 2.0 Select form Multiple selected

问题描述

我有此下拉菜单，您可以在其中选择多个值.现在，假设我要编辑我的信息并使用多个选定值创建一个下拉菜单.试图弄清楚进展如何，但没有结果.

I have have this dropdown menu where you can select multiple values. Now let's say I want to edit my info and make a dropdown menu with multiple selected values. Trying to figure out how it goes, but no results.

假设我有:

$selected = array(3, 4);
$options = array(1,2,3,4);

echo $this->Form->select('Attendees', $options,array('multiple' => true, 'selected' => $selected));

我已经使用了此代码，但未选择任何内容.

I've used this code, but nothing is selected.

推荐答案

确定了一种方法，显然它需要像这样:

Ok found a way, appearantly it needs to be like this:

$selected = array(2, 3);
$options = array(1, 2, 3, 4);

echo $this->Form->input('Attendees', array('multiple' => true, 'options' => $options, 'selected' => $selected));

将输出:

• 1
• 2
• 3个已选中
• 4个已选中

$ selected检查每个元素的索引键，而不是值本身.

The $selected checks the index key of each element rather the value itself.
