这篇文章主要介绍了关于thinkphp 下多图ajax上传图片，有着一定的参考价值，现在分享给大家，有需要的朋友可以参考一下

碰到一个项目，有一个比较繁琐的功能6个ajax上传，基本上每个上传逻辑多不一样，记录一下

thinkphp的view页面：

id方便找到这个元素 name一定要加 [ ]

<div class="btns">
　　<a href="javascript:;" class="a-upload">
　　　　<input type="file" id="fileaq" name="fileaq[]" data-filesType="words" class="uploadInput" multiple="multiple" />
　　　　<i class="iconfont icon-shangchuan"></i>上传附件
　　</a>
　　<a href="javascript:void(0)" class="submit" id="aq_sub">发布</a>
</div>

点击发布先判定一下，然后在把需要的参数传递给doUploadFiles函数

　　　　//发布案情
        $('#aq_sub').click(function() {            
        var guanxi = 'many_one';            
        var type_file = 'file';            
        var type_name = 'fileaq';            
        var anqing = $('#anqing').val();            
        if ($.trim(anqing).length == 0) {
                layer.alert('请输入内容!\n');
                $('#anqing').focus();                
                return false;
            } else {                
            var cate_id = 3;
                doUploadFiles(cate_id, type_file, type_name, guanxi, anqing);
            }
        })

参数说明

cate_id：多个上传的识别id

type_file: 判断是图片还是文件上传（nofiley：有的文件不需要上传）

type_name:上传文件的id

guanxi:关系项目需要参数分为many_one,many_many,one_one(多个用户每人一条数据，多个用户每人多条数据，多个用户一人一条数据)

content：内容

function doUploadFiles(cate_id, type_file, type_name, guanxi, content) {        
var guanxi = arguments[3] ? arguments[3] : 'many_one'; //设置关系
        var formData = new FormData();        
        var fangchan_id = $('#fangchan_id').val();
        formData.append("fangchan_id", fangchan_id);
        formData.append("cate_id", cate_id);
        formData.append("guanxi", guanxi);
        formData.append("content", content);        
        if(type_file !='nofile'){
            formData.append("type_file", type_file);
            formData.append("file_length", $("#"+type_name)[0].files.length);            
            for(var i=0; i<$("#"+type_name)[0].files.length;i++){
                formData.append('file[]',$("#"+type_name)[0].files[i]);
            }
        }

        $.ajax({
            url: '/Property/jindiaoHandle',
            type: 'POST',
            data: formData,
            dataType: "json",
            async: false,
            cache: false,
            contentType: false,
            processData: false,
            success: function(data) {
                console.log('上传:',data)                
                if (data.status == 200) {
                    layer.msg(data.msg, { icon: 1 });
                    window.location.reload();
                } else {
                    layer.msg(data.msg, { icon: 1 });                    
                    return false;
                }

            }

        });

    }
