我正在用我的例子来解释你,这个例子有问题、答案和调查
您可以使用多个复选框语法,如下所示:
$answers=array();
$tmp_ans=$question['Answer'];
for($j=0;$j < count($tmp_ans);$j++)
$answers[$tmp_ans[$j]['id']]=$tmp_ans[$j]['answer'];
echo '<li>';
echo $this->Form->input('Answer', array(
'type' => 'select',
'name'=>'Answer['.$question['Question']['id'].']',
'class'=>'test',
'label'=>false,
'multiple' => 'checkbox',
'options' =>$answers ,
));
echo '</li>';
之后,您将只有那些您检查过的答案,其他人不会出现在帖子数组中,因此要保存数据,您可以使用以下语法
if(!empty($this->data['Answer'])){
foreach ($this->data['Answer'] as $key=>$val):
if(!empty($val)):
if(is_array($val)):
foreach ($val as $ans):
$post_data['UserAnswer']['id']='';
$post_data['UserAnswer']['survey_id']=$id;
$post_data['UserAnswer']['user_id']=$this->Auth->user('id');
$post_data['UserAnswer']['question_id']=$key;
$post_data['UserAnswer']['answer_id']=$ans;
$this->UserAnswer->save($post_data['UserAnswer']);
endforeach;
else:
$post_data['UserAnswer']['id']='';
$post_data['UserAnswer']['survey_id']=$id;
$post_data['UserAnswer']['user_id']=$this->Auth->user('id');
$post_data['UserAnswer']['question_id']=$key;
$post_data['UserAnswer']['answer_id']=$val;
$this->UserAnswer->save($post_data['UserAnswer']);
endif;
endif;
endforeach;
}
