WeChat WEUI를 통해 이미지를 업로드하는 방법, 백그라운드 PHP에서 처리하는 방법은 무엇입니까?

질문: WeChat WEUI를 통해 이미지를 업로드하는 방법, 백그라운드 PHP는 이를 어떻게 처리해야 하나요?

1. 현재 직면한 문제는 애플리케이션의 weui 이미지 업로드 프레임워크이지만 코드의 미리보기 부분 li가 blob 유형의 이미지를 가져오는 것입니다. 그러나 Ajax를 통해 PHP에 제출된 입력은 하나만 있으며 마지막 그림만 얻을 수 있습니다.

<p class="weui-uploader__bd">
    <ul class="weui-uploader__files" id="uploaderFiles" >
        <li class="weui-uploader__file" style="background-image:url(&#39;/Public/Admin/images/pic_160.png&#39;)"></li>
        <li class="weui-uploader__file weui-uploader__file_status" style="background-image:url(&#39;/Public/Admin/images/pic_160.png&#39;)">
            <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. 백그라운드에서 $_FILES를 통해 하나의 입력만 얻을 수 있습니다. 어떻게 하면 모두 얻을 수 있나요? weui를 사용하여 사진 업로드를 어떻게 처리합니까?

솔루션

 //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 = &#39;<li id="#imgname#_li" class="weui-uploader__file" style="background-image:url(#url#)"></li>&#39;,
                $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(&#39;/&#39;); 
                    $uploaderFiles.append($(tmpl.replace(&#39;#url#&#39;, src).replace(&#39;#imgname#&#39;, 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"&#39;名称1&#39;,&#39;名称2&#39;，&#39;名称3&#39;"，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() == &#39;&#39; || $("#img_str").val() == null){
                       $("#img_str").val("&#39;"+src_split[src_split.length-1]+"&#39;");
                    }else{
                       $("#img_str").val($("#img_str").val()+",&#39;"+src_split[src_split.length-1]+"&#39;");
                    }
                    
                    //开启隐藏上传 p
                    $(this).after(&#39;<input id="uploaderInput"   name="result_file[]"  class="weui-uploader__input" type="file"   accept="image/*" multiple/>&#39;);
                    $(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(&#39;)&#39;);
                  imgback_array= imgback_array[0].split(&#39;/&#39;);
                  $("#"+imgback_array[imgback_array.length-1]+"_input").remove();
                  $("#"+imgback_array[imgback_array.length-1]+"_li").remove();
    
                  var img_str = $("#img_str").val().split(&#39;,&#39;);
                  var img_str_new = &#39;&#39;;
                  for(var i=0;i<img_str.length;i++){
                     if(img_str[i] != "&#39;"+imgback_array[imgback_array.length-1]+"&#39;"){
                         if(img_str_new == &#39;&#39;){
                             img_str_new = img_str[i];
                         }else{
                               img_str_new = img_str_new+","+img_str[i];
                         }
                     }
                  }
                  $("#img_str").val(img_str_new);
             });
