如何显示在CakePHP选择框中选择的选定值

Question

以下是我用于在selectbox中显示值的代码。但是如何显示下面代码中选择的值对我来说不起作用..

$currencyName = Array
(
    [$] => US Dollar 
    [$] => rdcyhgv976
    [€] => Euro
    [£] => UK Pound
    [¥] => Japanese yen
    [a] => a
    [b] => test
)

$selected=Array
(
    [Currency] => €
)

<?php 
echo $this->Form->input('SystemUser.Currency', array('type'=>'select','options'=> $currencyName, 'selected'=>$selected['Currency'], 'label' => false, 'div' => false, )); 
?>

任何人都可以告诉我哪里错了吗？

Answer 1

你试过吗

<?php 
echo $this->Form->input('SystemUser.Currency', array('type'=>'select','options'=>    $currencyName, 'default'=>$selected, 'label' => false, 'div' => false, )); 
?>

将“已选择”更改为“默认”。
