Is the html code containing php implementation self-reference?




Find the reason
If (! Empty ($ _ POST ['submit '])
Echo "It works ";
?>



This code is used to display it works when the form is submitted! But in fact, there is no reflection. I want to know what went wrong?

You do not specify the post submission method. by default, the get method is used for submission.

Don't rush to fix the basics first. Watch the video and read the manual.
