很好地看到了您的代码,您首先插入了记录,然后上载了文件。试着倒过来做。首先上传文件。如果成功,请将图片名称指定给变量
$pix
,然后在数据库中插入内容。并检查文件夹中的文件是否已成功上载到目录中。请尝试将此文件的名称与刚刚插入数据库的名称匹配

此外,请注意:

  • 避免使用不推荐的
    mysql\uu
    函数,选择
    mysqli\u
    或PDO
  • 使用参数化查询

    • 检查一下,我对你的代码做了一些修改

      你们查过数据库了吗。数据插入正确吗?数据插入正确,pic上传到服务器上的文件夹。我需要的是能够根据数据库中的id在一行上输出数据及其相应的图像,以便我以后可以根据其id和照片编辑每个项目名称。感谢您的回复。但是我在你代码的第二行有一个语法错误(刚才看到了问题所在。代码行缺少一个封闭的括号。非常感谢。你帮了我很大的忙。现在它工作正常。更进一步,如果我想通过单击链接编辑每个条目,该链接将我带到一个包含绑定到每个表单元素的表单的页面,请说文本字段绑定到名称字段在数据库中,文件字段绑定到database的photo字段,然后我可以编辑该特定条目的名称和图片,也可以删除。我可以单独使用文本,但不能使用图像。有什么帮助吗please@AgbogidiMichael我已经编辑了我的代码。虽然我不能理解你的问题,但是如果他不是你想要的告诉我所有你的帮助。我希望做的是,在每个名字之外都有一个编辑链接,当我点击它时,它会带我到一个有一个文本字段、文件字段和编辑按钮的表单页面。我想表单字段应该根据从数据库传递的id从数据库表中获得它们的值特定表项。表单代码下方:也感谢您的输入。在输入数据库之前,我将图像切换并上载到服务器。这有助于解决同名图像的覆盖问题。我还添加了rand()和time()函数来唯一标识每个图像。
