Answer 1

歡迎來到SO！

我發現了兩個小錯誤，我認爲它會做的伎倆：

1. 添加post方法的形式爲：<form method="post">
2. 添加name屬性至少要一個提交按鈕：
   • <input type="submit" name="submit" value="SUBMIT PROGRESS" class="button red" />

此外，建議使用JS來確定哪個提交按鈕已被點擊。例如，您可以添加一個隱藏的元素，並修改它的值：

echo '<input type="submit" value="GO TO PAINTING" ... onclick="$(\'[name=submit_clicked]\').val(\'no\');" />...'; 

... 

<form method="post"> 
    <input type="hidden" name="submit_clicked" value="yes" /> 
    ... 
</form>
