【问题描述】：

这是第一次需要将表单数据导出为特定文件夹中的 csv 文件。表单正在运行并导出 csv，但导出的 csv 文件仅显示逗号，没有任何信息。关于如何解决这个问题的任何想法？非常感谢任何建议。

【问题讨论】：

  • 如果你要问生成csv，你真的认为有必要展示10英里的html和验证码吗？而且如果你想将数据输出到一个csv文件，你不认为你应该使用实际定义的变量吗？在你的代码中搜索$varlname，看看它出现了多少次（以及在哪里）......
  • 请遵循此建议：stackoverflow.com/help/mcve 发布的大部分代码都是错误的
  • 因为（最可能的原因），fwrite() 函数中的所有变量都不正确。例如，您有$varfname，但您可能正试图从$fname = $_POST["fname"]; 等处获取它。
  • 或者只是打开寄存器全局变量（傻笑）
  • 将其更改为fwrite($fs,$fname . ", " . $lname . ", " . $email . ", " . $phone . ", " . $preferredContact . ", " . $signature ."\n");，它应该像骡子一样踢。我会把它作为答案，但我没有将蠕虫作为深夜小吃。但是，你说出这个词，我就像弗林一样。

【解决方案1】：

因为（也是最可能的原因），fwrite() 函数中的所有变量都不正确。

例如，您有$varfname，但它似乎与$fname = $_POST["fname"]; 等有关。

改成：

fwrite($fs,$fname . ", " . $lname . ", " . $email . ", " . $phone . ", " . $preferredContact . ", " . $signature ."\n");

编辑（已测试）

为了保留它们原来的位置，有些部分已经用/*...*/注释掉了，并且被放在了别处。

fwrite()函数已复制到mail()函数下，其他已注释掉。

以下内容对我有用，包括我原始答案的一部分。
