ajaxFileUpload+ThinkPHP+jqGrid 图片上传与显示
jqgrid上要显示图片和上传图片的列,格式如下:
{label:'图片',name:'icon',index:'icon',autowidth:true,formatter:alarmFormatter,editable:true,edittype:'custom',editoptions:{custom_element: ImgUpload,custom_value:GetImgValue}},
注意:edittype要为custom 也就是自定义编辑格式.
editoptions:{custom_element: ImgUpload,custom_value:GetImgValue}}
- 在
jqgrid的列表里显示图片用到的js function此处与图片的上传没关系.
function alarmFormatter(cellvalue,options,rowdata){
return '<img src="__MODULE__/download/download?id= '+ rowdata.icon + '"/>'
}
- 下面为上传用到的 js 文件
upload.js
/**
4. 自定义文件上传列
5. @param value
6. @param editOptions
7. @returns {*|jQuery|HTMLElement}
8. @constructor
*/
function ImgUpload(value,editOptions) {
var span = $("<span>");
var hiddenValue = $("<input>",{type:"hidden",val:value,name:"fileName",id:"fileName"});
var image = $("<img>",{name:"uploadImage",id:"uploadImage",value:'',style:"display:none;width:80px;height:80px"});
var el = document.createElement("input");
el.type = "file";
el.id = "imgFile";
el.name = "imgFile";
el.onchange = UploadFile;
span.append(el).append(hiddenValue).append(image);
return span;
}
/**
9. 调用 ajaxFileUpload 上传文件
10. @returns {boolean}
11. @constructor
*/
function UploadFile() {
$.ajaxFileUpload({
url : 'index.PHP/Home/upload/upload',type : 'POST',secureuri:false,fileElementId: 'imgFile',dataType : 'json',success: function(data,status){
//显示图片
$("#fileName").val(data.id);
$("#uploadImage").attr("src","index.PHP/Home/download/download?id=" + data.id);
$("#uploadImage").show();
$("#imgFile").hide()
},error: function(data,status,e){
alert(e);
}
});
return false;
}
/**
12. icon 编辑的时候该列对应的实际值
13. @param elem
14. @param sg
15. @param value
16. @returns {*|jQuery}
17. @constructor

function GetImgValue(elem,sg,value){
return $(elem).find("#fileName").val();
}

ajaxFileUpload+php图片上传预览
后台是利用SWFUpload上传图片，是flash+js的组合，如果不用chrome，经常会提示flash版本过低用不了，感觉还是很不方便的。
这里总结了一利用js ajax上传的插件列表： 7 JAVASCRIPT AJAX FILE UPLOAD PLUGINS
jQuery插件之ajaxFileUpload 原理都是创建隐藏的表单和iframe然后用JS去提交，获得返回值。
前台做的时候有一个坑，之前是用的$('element').change()来获取事件，但是onchange事件只会被触发一次，网上有提到解决的办法是live('change')，可惜项目jquery太旧并不支持，也不敢随意升级。所以只能直接在input中加入onchange=“function()”来实现。
这里有关于onchange事件的详细讲解:input的onchange事件实际触发条件与解决方法
一、当input捕获到焦点后，系统储存当前值
二、当input焦点离开后，判断当前值与之前存储的值是否不等，如果为true则触发onchange事件。
##前台代码 浏览器自己的file input比较丑，所以一般都display:none然后下面加一个
function uploadRear() {
$.ajaxFileUpload({
url:'{url:/ucenter/ajax_addr_identity_upload}',secureuri:false,fileElementId: 'strPhotoRear1',dataType: 'json',success: function (data) {
if(data.error == '200'){
$("#img-r").attr('src','{url:/' + data.data + '}');
$('input[name="card_id_reverse"]').val(data.data);
$('#strPhotoRear1').val();
} else {
art.dialog({
content: data.data
});
}
}
});
} ##php后台代码 利用了一个IUpload的类，foreach $_FILES，检查扩展名和图片木马，然后再上传。 先要了解PHP预定义变量$_FILES的格式：
Array
(
[file1] => Array
(
[name] => MyFile.txt (comes from the browser,so treat as tainted)
[type] => text/plain (not sure where it gets this from)
[tmp_name] => /tmp/php/php1h4j1o
[error] => UPLOAD_ERR_OK (= 0)
[size] => 123 (the size in bytes)
)
[file2] => Array
(
[name] => MyFile.jpg
[type] => image/jpeg
[tmp_name] => /tmp/php/php6hst32
[error] => UPLOAD_ERR_OK
[size] => 98174
)
) 这是在input name为file1和file2的情况，如果是写为file[img1],file[img2]，则处理为了以下模式（官方文档推荐了diverse_array(）的trick）：
Array
(
[file] => Array
(
[name] => Array
(
[img1] => MyFile.txt
[img2] => MyFile.jpg
)
... controller中的代码，返回处理后的消息给前台：
public function ajax_addr_identity_upload(){
$file_dir = 'upload/addr_identity/';
$uploader = new IUpload('5120'); //5M
$sub_dir = date('Y') . '/' . date('m') . '/'. date('d');
$uploader->setDir(trim($file_dir,'/') . '/' . $sub_dir);
$res = $uploader->execute();
//判断文件上传并生成数据
if ((isset($res['picfront']) && $res['picfront'][0]['flag'] == 1) || (isset($res['picback']) && $res['picback'][0]['flag'] == 1)) {
$return['error'] = '200';
$return['data'] = empty($res['picfront'][0]['fileSrc']) ? $res['picback'][0]['fileSrc'] : $res['picfront'][0]['fileSrc'];
$size = filesize($result['data']) / 1024;
$code = new Config('code_config');
$max_size = $code->card_id_max_size;
if($size > $max_size){
$proportion = number_format(($max_size/$size)*100);
$this->createThumb($return['data'],$proportion);
}
}
else
{
$return['error'] = '301';
$return['data'] = '上传失败';
}
echo json_encode($return);exit();
} IUpload类中比较关键的方法
public function setDir($path,$chmod=0777){
$dir = is_dir($path) or (self::mkdir(dirname($path),$chmod) and mkdir($path,$chmod));
$dir = strtr($dir,'\\','/');
$this->dir = substr($dir,-1)=='/' ? $dir : $dir.'/';
}
public function execute(){
//总的文件上传信息
$info = array();
foreach($_FILES as $fid => $file) {
$fileInfo = array();
//不存在上传的文件名
if(!isset($_FILES[$fid]['name']) || $_FILES[$fid]['name'] == '')
{
continue;
}
//上传控件为数组格式 file[]格式
if(is_array($_FILES[$fid]['name'])){
$keys = array_keys($_FILES[$fid]['name']);
foreach($keys as $key) {
//调用成员检查上传类型，pathinfo(）获取
$fileInfoArray = pathinfo($_FILES[$fid]['name'][$key]);
#code 检查上传大小 $_FILES[$field]['size'][$key]
#code 图片木马检测
#开始上传 is_uploaded_file/mkdir/move_upload_file(tmp_name,dir+name)
}
} else{
//非文件数组上传方式
#$fileInfo[0]['name'] = $_FILES[$field]['name'];
}
$info[$fid] = $fileInfo;
