前端调用  在`app/index/controller/Page`，`index`下添加下列代码
```php
  $investigation=db('investigation')->where(['vid'=>0])->where('id',1)->find();
        $data=db('investigation')->where(['vid'=>$investigation['id']])->order('sort desc')->select();
        $this->assign([
            'data'=>$data,
            'investigation'=>$investigation
   ]);
```
前端调用
```html
 <form class="layui-form" role="form" action="{:url('index/Vote/index')}" method="post">
            <input type="hidden" name="aid" value="{$investigation.id}">

<?php foreach ($data as $k => $v):?>
            <div class="layui-form-item">
                <div class="layui-input-block"><h2><?php echo $v['title'];?></h2></div>
                <div class="layui-input-block" style="padding-top: 15px;">
                    <?php switch ($v['cf_type']) {
                case 1:
                if($v['info']){
                $arr=explode(',', $v['info']);
                foreach ($arr as $k1 => $v1) {
                    echo "<input type='radio' name='".$v['id']."' value='".$v1."' title='".$v1."' >";
                    }
                    }
                    break;
                    case 2:
                    if($v['info']){
                    $arr=explode(',', $v['info']);
                    foreach ($arr as $k1 => $v1) {
                    echo "
                    <div class='checkbox' style='float:left; padding-left:10px;'>";
                        echo "
                        <div>";
                            echo "<input type='checkbox' name='".$v['id']."[]' value='".$v1."' class='colored-blue'>";
                            echo "<span class='text'>$v1</span> ";
                            echo "
                        </div>
                        ";
                        echo "
                    </div>
                    ";
                    }
                    }
                    break;
                    case 3:
                    echo "< textarea name='".$v['id']."' class='layui-textarea'></ textarea >";
                    break;
                    } ?>

</div>
            </div>
                <?php endforeach;?>

</div>
        </form>
```
js判断选项是否为空
```javascript
    $(function(){
        $(".add").click(function(){
//判断两个单选组被选中的值是否等于空
            if($(":radio[name='2']:checked").val()==null||$(":radio[name='3']:checked").val()==null){
                alert("单选项不可为空");
                location.reload();
            }
        })

})
```

提交添加数据 `add/index/controller` 下建 `Vote.php`文件
```php
<?php
/**

 * User: Administrator
 * Date: 2019/6/24
 * Time: 15:36
 */

namespace app\index\controller;
use think\Request;
class Vote extends Common
{
    public function index(){

if (request()->isPost()){
            $data=input('post.');
            $request=Request::instance();
            $votelog['ip']=$request->ip();
            $votelog['time']=time();
           $vote= new \app\index\model\Vote();
            $add=  $vote->addsex($data,$votelog);

if ($add==3){
                $this->error('此电脑已经投票过，无法重复投票！');

}
            if ($add==2){
                $this->error('请选择投票项！');

}
            if ($add==1) {
                $this->success('投票成功！','/','',1);
            }else{
                $this->error('投票失败！');
            }
      }
    }
}
```

提交添加数据 `add/index/model` 下建 `Vote.php`文件
```php
<?php

    public function addsex($data,$votelog){

$aid=$data['aid'];
        unset($data['aid']);

        foreach ($data as $k=>$v){

if ($v==''){
                return 2;
            }
            if (is_array($v)){

        }
        $time=strtotime(date('Y-m-d 00:00:00'));
        $logip= db('votelog')->where('ip',$votelog['ip'])->where('time','>',$time)->find();
        if (!$logip){
            $votelogip= db('votelog')->insert($votelog);
            if ($votelogip) {

        }

$add=db('voetadd')->insertAll($votearr);
        if ($add) {
            return 1;
