Php 是否将图像上载存储在文件夹=到会话id?
我有一个脚本可以将照片上传到“file/”目录。 我想这样做,以便在“文件”目录中有另一个文件夹,该文件夹标记为登录用户的会话id。因此,如果用户“1”上传照片,它将转到“file/1/default.jpg”,如果用户“2”上传照片,则转到“file/2/default.jpg” 谁能告诉我怎么做。谢谢 html:Php 是否将图像上载存储在文件夹=到会话id?,php,image,session,upload,Php,Image,Session,Upload,我有一个脚本可以将照片上传到“file/”目录。 我想这样做,以便在“文件”目录中有另一个文件夹,该文件夹标记为登录用户的会话id。因此,如果用户“1”上传照片,它将转到“file/1/default.jpg”,如果用户“2”上传照片,则转到“file/2/default.jpg” 谁能告诉我怎么做。谢谢 html: $('#sampleform')。提交(函数(e){ e、 预防默认值(); $.ajax({ url:$(this.attr('action'), 类型:'post', 数据:

编辑:我在
upload.php中未找到session\u start()
,如果会话中存储了用户的session\u id变量,请使用session\u start()
位于文件顶部。谢谢,但这不会改变任何事情。图像仍在上载到“files/”中,并且没有创建具有会话id的目录。您是否也可以显示HTML部分,以确保有关POST值的信息。哪里是$\u POST['value',$\u POST['folder']
在你的HTML部分??指的是你的值,文件夹
?我不太清楚它为什么使用这些值。我把session_start()放在upload.php文件的顶部,它现在创建了一个带有会话id的文件夹,但它把它放在“files/”之外,图像仍然存储在“files/”@date('Y-m-d H:i:s')
