CakePHP选择框值不正确后

问题描述：

//My Owner Model 
var $belongsTo = array(
    'Owner' => array(
     'className' => 'User', 
     'foreignKey' => 'owner', 
    ), 
); 

//My Tickets Controller 

//Find the owners of the ticket to build select box 
$owners = $this->Ticket->Owner->find('list', array(
     'fields' => array('Owner.id', 'Owner.username') 
     'order' => array('Owner.username' => 'asc') 
)); 

//Add "All" to the array of owners at 0 (no owner ids are 0) 
array_splice($owners, 0, 0, "All"); 
//Set owner variable in my view. 
$this->set(compact('owners')); 

//My template file or view 
echo $this->Form->create('Ticket', array(
    'url' => array_merge(array('action' => 'find'), $this->params['pass']))); 
    echo $this->Form->input('title', array('div' => false)); 
    echo "<br /><br />"; 
      //Build the selectbox ordered by username 
    echo $this->Form->input('owner', array('div' => false, 'options' => $owners, 'id' => 'EndUser')); 
    echo "<br /><br />"; 
    echo $this->Form->submit(__('Search', true), array('div' => false)); 
    echo $this->Form->end();

当选择框建立时，选择框按用户名排序喜欢我喜欢 - 但他们的ID不切换用户名。CakePHP选择框值不正确后

如果我在array_splice($owners, 0, 0, "All");之前做了print_r($owners)这个数组是正确的。当我 array_splice($owners, 0, 0, "All");后阵列是不正确的 - 但我不知道为什么...我假设array_splice重新编号的数组...如何可以添加“任何”到阵列而不会搞乱我的关系？

我想通了 - 但不能回答我的问题。显然你可以添加数组 - 谁知道！（我相信可能是大多数人！ //全部添加到数组顶部 $ allarray = array（0 =>“All”）; $ owners = $ allarray + $ owners; – dingerkingh 2012-03-20 11:12:17

你最好使用表单助手的输入法empty选项。你可以沿着钥匙去与它擦肩而过，所以更改：

echo $this->Form->input('owner', array('div' => false, 'options' => $owners, 'id' => 'EndUser'));

要这样：

echo $this->Form->input('owner', array(
    'div' => false, 
    'options' => $owners, 
    'empty' => array(0 => 'All'), // Add this line 
    'id' => 'EndUser' 
));

真棒 - 这甚至更好！谢谢！ – dingerkingh 2012-03-20 11:38:26

试试这个

$owners = $this->Ticket->Owner->find('list', array(
     'conditions' => array('Owner.id NOT'=>'0') 
     'fields' => array('Owner.id', 'Owner.username') 
     'order' => array('Owner.username' => 'asc') 
));
