Ajax图片上传,其中图片获取日期时间戳添加到FILENAME中,图片标题通过MYSQL插入 [英] Ajax image upload where image gets datetimestamp added to FILENAME and image title get's inserted through MYSQL
问题描述
是否有任何AJAX PHP Jquery MySQL插件,您可以上传多个文件(最好是拖放操作),并将其datetimestamp添加到实际的FILENAME(文件名存储在服务器上的文件夹中).您还可以在其中选择插入到MySQL数据库中的图块和说明(mysql行将具有以下列:USER_ID,IMAGE_FILENAME,TITLE,DESCRIPTION).我正在尝试为基于用户的网站的用户创建图片数据库.
Is there any AJAX PHP Jquery MySQL plugin that you can upload multiple files (preferably drag-drop), that add's datetimestamp to the actual FILENAME (where it stores in a folder on the server). Also where you can choose a tile and description that inserts into a MySQL database (the mysql row is going to have the columns as follows: USER_ID,IMAGE_FILENAME,TITLE,DESCRIPTION). I am attempting to make a database for the pictures for my users of my user-based website.

我已经尝试过适当地修改它,只是无法使其正常工作...我喜欢设计,功能还不完善.有什么想法或建议可以解决我的问题吗?
I've tried modding this properly, just couldn't get it to work...I like the design, functions aren't quite there. Any ideas or suggestions that meet my question?

推荐答案
与您的代码一起,尝试:
Together with your code, try:
替换此块:
/*
var d = new Date();
var curr_date = d.getDate();
var curr_month = d.getMonth() + 1; //Months are zero based
var curr_year = d.getFullYear();
var fulldatetime = ""+ curr_date + "-" + curr_month + "-" + curr_year +"";
*/
使用:
var d = new Date();
var fulldatetime = d.getDate() + "-"
+ (d.getMonth()+1) + "-"
+ d.getFullYear() + "--"
+ d.getHours() + "-"
+ d.getMinutes() + "-"
+ d.getSeconds();
然后:
var filename = files[i].name;
var ext = filename.substring(filename.lastIndexOf(".")+1).toLowerCase();
/* this line added */
var file_date = fulldatetime+'_'+filename;
var allowed= "";
if(ext == "jpg" || ext == "png" || ext == "gif" || ext == "jpeg")
{
var fd = new FormData();
fd.append('file', files[i]);
/* this line added */
fd.append('fileDateTime',file_date);
var status = new createStatusbar(obj); //Using this we can set progress.
其余代码保持不变.您可以在upload.php
The rest of your code remains the same. You can address the new file name with $_POST['fileDateTime'];
on your upload.php
要将重命名的文件传递给createStatusbar()
,请更改函数定义:
To pass the renamed file to createStatusbar()
, change the function definition:
来自:
/* function createStatusbar(obj) */
收件人:
function createStatusbar(obj,file_date)
在通话期间:
/* var status = new createStatusbar(obj); //Using this we can set progress.*/
收件人:
var status = new createStatusbar(obj,file_date); //Using this we can set progress.
file_date
是保存新文件名的变量,然后您可以根据需要使用它.
file_date
is the variable that holds the new file name, you can then use it as you need.
