Answer 1

In this line:

if(empty($_POST['offered'])===true||($_POST['description']===true))

You only check if $_POST['offered'] is empty, and you check if the $_POST['description'] is true (not what you want to do). You need to perform the empty() on $_POST['description'] as well.

if(empty($_POST['offered'])===true||empty($_POST['description'])===true)

Answer 2

如果我给出此代码，则如果所有字段均已填写，则无法给出成功消息

 if(empty($_POST['offered'])===true||empty($_POST['description'])===true)
