上传接口代码
//通用缩略图上传接口

控制器代码
//添加
public function add()

//halt($oldData);

}
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()];
}
}
//修改
/**
* 编辑
*/

//$data['cc'] = json_decode($data['bb']);
//halt($data);
}
//allowField过滤post数组中的非数据表字段数据
$res = $this->validate( true )->allowField(true)->save( $data , [ $this->pk => $data[ 'cp_id' ] ]);
if ($res) {
return [ 'valid' => 1 , 'msg' => '操作成功' ];
}
else {
return [ 'valid' => 0 , 'msg' => '操作失败'];
}
