Php 迷你AJAX文件在同一页面上上载多个上载块
我正在使用以下插件: 我的问题是在同一页面上有多个上载实例(例如1页眉图像2页脚图像) 但是只有第一个输入真正起作用,另一个不起作用,我没有得到错误的客户端或服务器端 如果我在谷歌上尝试寻找替代方案,我会得到数百万次“同时多次上传”,这不是我想要的 以下是页面代码:Php 迷你AJAX文件在同一页面上上载多个上载块,php,javascript,jquery,ajax,file-upload,Php,Javascript,Jquery,Ajax,File Upload,我正在使用以下插件: 我的问题是在同一页面上有多个上载实例(例如1页眉图像2页脚图像) 但是只有第一个输入真正起作用,另一个不起作用,我没有得到错误的客户端或服务器端 如果我在谷歌上尝试寻找替代方案,我会得到数百万次“同时多次上传”,这不是我想要的 以下是页面代码: <form id='upload' method='post' action='URLtoServerside' enctype='multipart/form-data'> &l

有人可以告诉我如何让这个工作在同一个页面上的多个上传,或推荐一个替代方案
(我确实需要拖放和“浏览”功能)
js
var attachname=“attach”;
var i=1;
函数addInput(){
如果(i>0){
var attach=attachname+i;
如果(创建输入(附加))
i=i+1;
}
}
函数createInput(nm){
var AEElement=document.createElement(“输入”);
aeelement.name=nm;
aElement.id=nm;
aElement.type=“文件”;
aeelement.size=“50”;
if(document.getElementById(“upload”).appendChild(AEElement)==null)
返回false;
返回true;
}
我刚遇到这个问题 我的解决方案: 我用script2.js或其他东西从miniupload复制script.js。 在那个脚本中,我做的唯一一件事就是将名称从upload改为upload\u文件,再从drop改为drop\u文件。 像这样:
var ul = $('#upload_files ul');
$('#drop_files a').click(function(){
// Simulate a click on the file input button
// to show the file browser dialog
$(this).parent().find('input').click();
});
// Initialize the jQuery File Upload plugin
$('#upload_files').fileupload({
(...)
我的HTML:
<form id="upload" method="post" enctype="multipart/form-data">
<div id="drop" style="text-align:center ;align-content:center">
Add images
<a>Select</a>
<input type="file" name="upl" multiple />
</div>
<ul>
<!-- The img uploads will be shown here -->
</ul>
</form>
<form id="upload_files" method="post" enctype="multipart/form-data">
<div id="drop_files" style="text-align:center ;align-content:center">
Add files
<a>Select</a>
<input type="file" name="upl_file" multiple />
</div>
<ul>
<!-- The file uploads will be shown here -->
</ul>
</form>
我添加了反映上传文件的代码
#upload_files{
font-family:'PT Sans Narrow', sans-serif;
background-color:#373a3d;
background-image:-webkit-linear-gradient(top, #373a3d, #313437);
background-image:-moz-linear-gradient(top, #373a3d, #313437);
background-image:linear-gradient(top, #373a3d, #313437);
width:250px;
padding:30px;
border-radius:3px;
margin:20px 20px 20px;
box-shadow: 0 0 10px rgba(0, 0, 0, 0.3);
}
这不是一个“干净”的解决方案,但它是有效的:)我有这个问题很久了,直到我想我会解决它。这就是我所做的 在表单中,我向
#upload
和#drop
元素添加了类。我将它们重命名为#upload1
,#upload2
和#drop1
,#drop2
<form id="upload1" class="upload" method="post" action="upload.php" enctype="multipart/form-data">
<div id="drop1" class="drop">
...
我还将#upload
的所有实例替换为$this
,将#drop
的所有实例替换为$this.find('.drop')
基本上,您将用类名替换ID,并相应地调整脚本,并将其全部封装在一个大的each循环中
另外,我还喜欢在我的脚本文件中添加一个完整的回调,这样我就可以完成所有事情
complete:function() {
},
请让我知道这是否适合你
