dropzone.js默认是Ajax上传图片给服务器,那么如何获取到图片名呢?其实我们是可以通过dropzone的success函数获取到服务器返回的数据
dropzone.js在HTML的配置如下;
Dropzone.autoDiscover = false;//防止报"Dropzone already attached."的错误
$(".dropzone").dropzone({
url: "__URL__/upload/",
addRemoveLinks: true,
dictRemoveLinks: "x",
dictCancelUpload: "x",
paramName:"userImg",
maxFiles: 10,
maxFilesize: 5,
acceptedFiles: "image/*",
init: function() { //res为服务器响应回来的数据
this.on("success", function(file, res) { //将json字符串转换成json对象
var obj = JSON.parse(res); //res为dropzone.js返回的图片路经
file.path = res; if( obj.status == 200 ){ //将服务器得到的数据生成一个隐藏域。做商品添加的时候就可以获取到了
var input = '<input type="hidden" name="'+obj.details.savename+'" value="'+obj.details.savepath+obj.details.savename+'" />';
$('.myform').append(input); }else{
alert('上传失败');
} }); this.on("removedfile", function(file) { $.ajax({
url: "改成你的php删除图片的路径",
type: "post", //file.path可以获取到点击删除按钮的那张图片
data: { 'path': file.path }
});
}); }
});
PHP的代码如下(Thinkphp代码):
public function upload()
{ /*
添加商品 :商品名、商品图片
*/ // 实例化上传类
$upload = new \Think\Upload(); // 设置附件上传大小
$upload->maxSize = 3145728 ; // 设置附件上传类型
$upload->exts = array('jpg', 'gif', 'png', 'jpeg'); //A开发者写了upload() B开发
// 设置附件上传目录
$upload->savePath = './Public/Uploads/'; //返回上传信息
$info = $upload->uploadOne($_FILES['userImg']);
// dump($info);exit;
if( !$info ) {
// 上传错误提示错误信息
// $this->error($upload->getError());
$data['status'] = 404; //错误信息
$data['msg'] = $upload->getError(); echo json_encode($data); }else{
// 上传成功 (图片路径、图片名字) $data['status'] = 200;
$data['msg'] = 'UPLOAD SUCCESS'; //图片原始名字
$data['details']['originName'] = $info['name'];
$data['details']['savename'] = $info['savename'];
$data['details']['savepath'] = $info['savepath']; echo json_encode($data);
}
}
