现在我真的很困惑，现在已经在这个问题上工作了几个小时，所以我想我会在这里发帖，也许会得到一些反馈。所以我有一个程序在一个文件上运行这个搜索工具。该文件来自生成到文件中的用户输入或实际上载文件的用户。我有2个提交按钮，第一个按钮用户生成的文件，第二个按钮用于上传文件的用户。
我遇到的问题是我有第二个提交按钮的相同的确切代码（所有更改是程序获取文件的方式）但由于某种原因，第二个提交按钮不起作用。不会生成任何内容，也不会执行搜索工具。我知道这是因为没有创建输出文件。
我想知道是否有人知道为什么我的第二个按钮不像第一个按钮那样......
这是我的代码......

我不明白。基本上exec函数在第一个提交按钮中工作，但是exec函数在第二个中不起作用...我可以进入终端并运行第二个exec函数，它运行得非常好。是因为第二次提交的动作是upload.php吗？我可以看到它......
EDIT1：我刚尝试专门为该按钮创建一个新表单，并使操作与第一个提交按钮表单相同。它没有工作:(任何帮助表示赞赏！
答案 0 :(得分：0)
您的代码中粘贴的问题很少。
textarea没有结束标记。method="Post" 答案 1 :(得分：0)
在method = POST之后那个逗号应该存在吗？我实际上无法理解为什么它会产生任何影响，但它无法提供帮助。在页面上有多个表单当然是有效的，但有时候只有一个表单并且在多个＆＃39; normal＆＃39;后面使用Javascript更好。按钮设置enctype，方法，操作集和必需的默认值，然后以编程方式提交表单。
答案 2 :(得分：-1)
在相应的表单中提供以下隐藏的输入，以便在服务器端php获取$ _POST [＆＃39; submit＆＃39;]和$ _POST [＆＃39; submit2＆＃39;]：
<input type="hidden" value="1" name="submit" />
<input type="hidden" value="1" name="submit2" />
试试这个：
