You can try to achieve it in this way:您可以尝试通过以下方式实现它：

on every page looking for some $_POST value, for example if (isset($_POST['refer']))在每个页面上寻找一些 $_POST 值，例如if (isset($_POST['refer']))
if isset the value that you're looking for print the page content, otherwise print error, redirect to homepage or do what you want to do when the user come in the page without clicking on your button如果设置了您要查找的值打印页面内容，否则打印错误，重定向到主页或在用户进入页面时执行您想做的事情而无需单击您的按钮
modify your button, on click not only redirect the user but submit a form with the wanted post value修改您的按钮，单击时不仅会重定向用户，还会提交带有所需帖子值的表单

You can add your value directly into button value您可以将您的值直接添加到按钮值中

<form action="/yourpage.php" method="post">
  <button name="subject" type="submit" value="VALUE_TO_SEND">BUTTON 
TEXT</button>
</form>

VALUE_TO_SEND can be: the current url, or what you want to use to check the refer VALUE_TO_SEND可以是：当前的url，或者你想用什么来检查引用
