}添加控制器代码//添加
public function add()
{
if(request()->isPost())
{
//dump(input('post.'));
$res = $this->db->tianjia(input('post.'));
if($res['valid'])
{
$this->success($res['msg']);
}else{
$this->error($res['msg']);
}
}
return $this->fetch();
}添加模型代码//添加
public function tianjia($data)
{
//halt($data);
$count = count($data['pc_src']);//获取传过来有几张图片
if($count){
for($i = 0;$i< $count;$i++){
$data['pics'][]=array("src"=>$data['pc_src'][$i]);
}
$data['pics'] = json_encode($data['pics']);
//$data['cc'] = json_decode($data['bb']);
//halt($data);
}
$result = $this->validate(true)->allowField(true)->save($data);
if($result){
// 验证失败 输出错误信息
return ['valid'=>1,'msg'=>'添加成功'];
//dump($this->getError());
}else{
return ['valid'=>0,'msg'=>$this->getError()];
