问题：通过微信weui实现图片上传，后台php该如何处理？
1.目前遇到的问题为应用的weui图片上传框架，但代码中预览部分li获取到了类型是blob的图片。但只有一个input，通过ajax提交到php，只能获取到最后一张图片。
<p class="weui-uploader__bd">
<ul class="weui-uploader__files" id="uploaderFiles" >
<li class="weui-uploader__file" style="background-image:url('/Public/Admin/images/pic_160.png')"></li>
<li class="weui-uploader__file weui-uploader__file_status" style="background-image:url('/Public/Admin/images/pic_160.png')">
<p class="weui-uploader__file-content">50%</p>
</li>
</ul>
<p class="weui-uploader__input-box">
<input id="uploaderInput" name="photo" class="weui-uploader__input" type="file" accept="image/*" />
</p>
</p>2.通过后台进行$_FILES只能获取到一个input。怎么才能获取所有的？大家用weui上传图片的时候是怎么处理的呢？
贴上图片photo不加[]的情况下，获取的到的是

解决方法
//解决思路如下: 通过改写他的文件隐藏域，每次选择一个图片之后，自动隐藏当前file，然后通过js插入一个新的空文件 type=“file”,这样就可以实现多文件上传。改写代码如下：
$(function(){
var tmpl = '<li id="#imgname#_li" class="weui-uploader__file" style="background-image:url(#url#)"></li>',
$gallery = $("#gallery"), $galleryImg = $("#galleryImg"),
$uploaderInput = $("#uploaderInput"),
$uploaderFiles = $("#uploaderFiles")
;
//此处的on 需要改成 live ,因为jquery插入html，js事件会失效，采用live
$uploaderInput.live("change", function(e){
var src, url = window.URL || window.webkitURL || window.mozURL, files = e.target.files;
for (var i = 0, len = files.length; i < len; ++i) {
var file = files[i];
if (url) {
src = url.createObjectURL(file);
} else {
src = e.target.result;
}
var src_split = src.split('/');
$uploaderFiles.append($(tmpl.replace('#url#', src).replace('#imgname#', src_split[src_split.length-1])));
//其中img_str 为我自己写的隐藏文本框，用来存放所有的图片名称组成的字符,类似"'名称1','名称2'，'名称3'"，因为我用这个隐藏框的值，来删除页面页面的指定图片。
if($("#img_str").val() == '' || $("#img_str").val() == null){
$("#img_str").val("'"+src_split[src_split.length-1]+"'");
}else{
$("#img_str").val($("#img_str").val()+",'"+src_split[src_split.length-1]+"'");
}
//开启隐藏上传 p
$(this).after('<input id="uploaderInput" name="result_file[]" class="weui-uploader__input" type="file" accept="image/*" multiple/>');
$(this).hide();
$(this).attr({id:""+src_split[src_split.length-1]+"_input"});
}
});
$uploaderFiles.on("click", "li", function(){
$galleryImg.attr("style", this.getAttribute("style"));
$gallery.fadeIn(100);
});
$gallery.on("click", function(){
$gallery.fadeOut(100);
});
//删除图片 删除图片的代码也贴出来。
$(".weui-gallery__del").click(function(){
var imgback = $(this).parent("p").prev().attr("style");
var imgback_array= imgback.split(')');
imgback_array= imgback_array[0].split('/');
$("#"+imgback_array[imgback_array.length-1]+"_input").remove();
$("#"+imgback_array[imgback_array.length-1]+"_li").remove();
var img_str = $("#img_str").val().split(',');
var img_str_new = '';
for(var i=0;i<img_str.length;i++){
if(img_str[i] != "'"+imgback_array[imgback_array.length-1]+"'"){
if(img_str_new == ''){
img_str_new = img_str[i];
}else{
img_str_new = img_str_new+","+img_str[i];
}
}
}
$("#img_str").val(img_str_new);
});
});
