使用jsp编辑上载表格

问题描述 投票：0回答：1

我有一个index.jsp页面。在此页面中，用户将填写zid，firstname，lastname等字段。在填写字段时，用户选择要上传到MySQL数据库的文件，然后单击“提交”，然后文件将被存储为详细信息。存储的记录显示在filelist.jsp页面中。我已经创建了一个文件夹作为“ allfiles”，所有用户上传的文件都将存储在该文件夹中并成功执行。我也有一个filelist.jsp页面，在这里我使用了此sql查询从数据库select * from dmsfiles中获取所有记录。所有记录都以表格形式（列和行）获取。在此filelist.jsp页面中，我有一个“编辑表单”列来编辑表单（index.jsp）。如果用户要编辑任何文件，则他/她单击“编辑”，然后index.jsp将打开，然后用户根据需要进行一些更改，然后单击“更新”。现在的问题是，当我单击“编辑”以获得任何记录时，多个表单（index.jsp）正在彼此打开。我知道为什么会这样，但我没有解决办法。发生这种情况的原因是，如果假设用户zid = 1234存储了4个文件，则4条记录正在显示在filelist.jsp 具有相同的zid中。当我单击任何“编辑”时，将打开4个表单（index.jsp）。我想要的是，当我单击任何“编辑”时，仅应打开相应的表单（index.jsp）。

我已经在editnew.jsp下面尝试过

您是否还可以将文件路径作为查询参数传递给editnew.jsp并检查
