我点击了父页面上的提交按钮和页面刷新,但值未更新。
有人可以在这指导我吗?
很抱歉发布这么长的代码,因为我希望你们能够理解我正在做的更多。 TQ

您的committee_assign.php中没有input
名为submit:
if(isset($_POST['submit']))
你必须检查这样的事情:
if(isset($_POST))

您正在检查提交是否已发布,但您没有名为“提交”的输入。添加一个名为submit的输入,其中包含一些值并检查该帖子是否存在。如果你不想看到额外的输入,你可以隐藏它。
if($ _ POST ['submit'])正在检查post数组中是否有值为'submit'的值。 $ _POST数组中的所有键和值分别是表单元素的名称和值。
