大家好,我在写Saingwa老师讲的新闻资讯类后台文章管理系统,为什么上传完显示无缩略图

Question

大家好，我在写Saingwa老师讲的新闻资讯类后台文章管理时，为什么上传完显示无缩略图，求大神解答，以下是代码：

<?php
/*
*图片相关
*/
namespace Admin\Controller;
use Think\Controller;
use Think\Upload;

/*
*
* 文章内容管理
*/

class ImageController extends CommonController{
private $_uploadobj;
public function __construct(){

}


//异步上传方法
public function ajaxuploadimage(){
$upload = D("UploadImage");
$res = $upload->imageUpload();
if($res===false){
return show(0,'上传失败', ' ');

}else{
return show(1,'上传成功',$res);
}
}
//文本编辑器的接受
public function kindupload(){
$upload = D("UploadImage");
$res = $upload->upload();
print_r($res);
exit;
if($res===false){
return showkind(1,'上传失败');
}
return showkind(0,$res);

}

}

?>

上面的代码是ImageController.class.php

<?php
namespace Common\Model;
use Think\Model;

/**
* 上传图片类
* @author singwa
*/
class UploadImageModel extends Model {
private $_uploadObj = ' ';
private $_uploadImageData = ' ';

const UPLOAD = 'upload';

public function __construct() {
$this->_uploadObj = new \Think\Upload();

$this->_uploadObj->rootPath = './'.self::UPLOAD.'/';
$this->_uploadObj->subName = date(Y) . '/' . date(m) .'/' . date(d);
}

public function upload() {
$res = $this->_uploadObj->upload();

if($res) {
return '/' .self::UPLOAD . '/' . $res['imgFile']['savepath'] . $res['imgFile']['savename'];
}else{
return false;
}
}

public function imageUpload() {
$res = $this->_uploadObj->upload();
// print_r($res);exit;

if($res) {
return '/' .self::UPLOAD . '/' . $res['file']['savepath'] . $res['file']['savename'];
}else{
return false;
}
}
}
上面的这段代码是UploadImageModel.class.php

下面的代码是Image.js

/**
* 图片上传功能
*/
$(function() {
$('#file_upload').uploadify({
'swf' : SCOPE.ajax_upload_swf,
'uploader' : SCOPE.ajax_upload_image_url,
'buttonText': '上传图片',
'fileTypeDesc': 'Image Files',
'fileObjName' : 'file',
//允许上传的文件后缀
'fileTypeExts': '*.gif; *.jpg; *.png',
'onUploadSuccess' : function(file,data,response) {
// response true ,false
if(response) {
var obj = JSON.parse(data); //由JSON字符串转换为JSON对象

console.log(data);
$('#' + file.id).find('.data').html(' 上传完毕');

$("#upload_org_code_img").attr("src",obj.data);
$("#file_upload_image").attr('value',obj.data);
$("#upload_org_code_img").show();
}else{
alert('上传失败');
}
},
});
});

<div class="form-group">
<label for="inputname" class="col-sm-2 control-label">缩图:</label>
<div class="col-sm-5">
<input id="file_upload" type="file" multiple="true" >
<img style="display: none" id="upload_org_code_img" src="" width="150" height="150">
<input id="file_upload_image" name="thumb" type="hidden" multiple="true" value="">
</div>
</div>
