我从模型中创建 2 个数组，其中 1 个是用户已经选择的值，第二个可用值是用户也可以选择的。这适用于编辑页面。我想用两个模型的值填充多选输入框，但希望突出显示已选择的值（第一个数组）。它很好地创建了模型，并且使用 array_merge（） 合并了两个数组作为选项，但所选字段没有突出显示正确的字段。有什么提示吗？
// Controller:
$ivrNumbersAvail = $this->Survey->SurveyIvrNumber->find("list",array("conditions" => array("OR" => array("SurveyIvrNumber.survey_id" => array($id)))));
$ivrNumbersSelected = $this->Survey->SurveyIvrNumber->find("list",array("conditions" => array("OR" => array("SurveyIvrNumber.survey_id" => array(0)))));
// In the view:
echo $this->Form->input('SurveyIvrNumbers.id',array(
'empty' => '-- Select IVR Number(s) --',
'options' => array_merge($ivrNumbersAvail,$ivrNumbersSelected),
'selected' => $ivrNumbersSelected,
'class' => 'textbox',
'multiple' => true,
'div' => array(
'class' => 'field'
),
'label' => array(
'class' => 'label-tooltip',
'title' => '', //tool tips
'text' => 'IVR Numbers: (you can select multiple numbers)'
),
'after' => '<p class="field-help"></p>'
));
如果您将$this->request->data设置为您当前正在编辑的记录，CakePHP 将自动为您填充此数据！
// CONTROLLER
// this line sets the data
$this->request->data = $this->Survey->read(null, $id);
// this passes the SurveyIvrNumbers to the view, (you can put any options on to this)
$this->set('SurveyIvrNumber',$this->Survey->SurveyIvrNumber->find('all'));
// VIEW
// CakePHP does the rest
echo $this->Form->input('SurveyIvrNumbers',array(
'empty' => '-- Select IVR Number(s) --', // plus other options
);
