在HABTM复选框旁边显示图像

我假设在你的控制器中你做了类似的事情:

$this->request->data = $this->Item->find('first',  ... ); 

因此 $data 以子阵列的形式包含关于所选特征的信息,

编辑: 我还假设 Item 哈比姆语 ItemCharacteristic

那么在你看来

$checked_characteristics = Hash::extract($this->data, 'ItemCharacteristic.{n}.id');
foreach($itemCharacteristics  as $id => $itemCharacteristic )
{
    $checked = in_array($id, $checked_characteristics );
    $img = $this->Html->image('cake.icon.png'); // put here the name 
                                                // of the icon you want to show
                                                // based on the charateristic 
                                                // you are displayng
    echo $this->Form->input(
        'ItemCharacteristic.ItemCharacteristic.', 
        array(
            'between' => $img, 
            'label' => $itemCharacteristic, 
            'value' => $id,  
            'type' => 'checkbox',
            'checked' => $checked
        )
    );
}

编辑:从你的评论中我理解 $itemCharacteristics 来自 find('list' )声明。

将其更改为 find('all', array('recursive' => -1));

现在您的代码变成

foreach($itemCharacteristics  as $itemCharacteristic )
{
    $id = $itemCharacteristic['ItemCharacteristic']['id'];
    $icon_name = $itemCharacteristic['ItemCharacteristic']['icon_name']; //or wherever you get your icon path
    $img = $this->Html->image($icon_name); 
    $itemCharacteristicName = $itemCharacteristic['ItemCharacteristic']['name'];
    // same as above
}
