关于jquery图片上传功能呢，我引入了

jquery.min.js
jquery-1.8.3.min.js
jquery.ui.widget.js
jquery.iframe-transport.js
jquery.fileupload.js

上传图片的代码：

图片上传成功之后，可以选择删除！里面的变量就是我从数据库查出来的，数据库当然存放的是图片的路径了！


这是单张图片上传的html代码

    产品相册
     
    
        
        
        " name="goodsimg" />
        " 
        style=" width:100px; height:100px; margin:10px; display:none;" id="goodsimg" />
        
            
        
    

这是多张图片上传的html代码

    企业证书
     
    
        
        
        " name="Certiimg" />
        
            
                    
  • " style=" width:100px; height:100px; margin:10px; display:block;" id="Certificateimg" />
                        
                            
                        
                    
    • 
                    
        
    

    上传的js代码：

      $(function (){
        var goodsimg = $("#goodsimg").attr("src");
        //单张图片显示
        if(goodsimg!=""){
               $("#goodsimg").css("display","block");
               $(".delgoodsimg").css("display","block");
        }
        //单张图片删除
        $(".delgoodsimg").click(function (){
              $("input[name='goodsimg']").val("");
              $("#goodsimg").css("display","none").attr("src","");
              $(this).css("display","none");
        });
        //多条副
        $(".delCertificateimg").live('click',function(){
            var delindex = $(this).parents("li").length;
            var Certiimgval = $("input[name='Certiimg']").val();
            var Certiimgarr = Certiimgval.split("|");
            Certiimgarr.pop();
            if(Certiimgarr.length == 0){
                $("input[name='Certiimg']").val("");
            }else{

                $("input[name='Certiimg']").val(Certiimgval);
            }
            $(this).parents("li").remove();
        });

        //jquery图片上传

                    alert("上传图片多于2张，请删除一张图片后重新上传");
                    return false;
                }
                var certidom = '
    • ';
                $(".Certidom").append(certidom);

backend_upload_photo.php文件就是上传图片后台代码处理图片的地址
结合上传图片的地方来写此部分
$fileExtArr = explode(".",$_FILES['_goodsFile']['name']);
$fileExt = ".".$fileExtArr[1];
//图片存放地址进行名字随机给处理
$path='/backend/actions/upload/'.time().md5($_FILES['_goodsFile']['name'].rand()).$fileExt;
move_uploaded_file($_FILES['_goodsFile']['tmp_name'],$_SERVER['DOCUMENT_ROOT'].$path);
echo json_encode(array("flag"=>1,"img"=>"..".$path));
