HTML Help: Stop php from clearing a form? What is ‘/’ at the end of an input field?

  Kiến thức lập trình

First, HTML is not in my professional toolbox. I’m just trying to muddle through to make a simple form work.

I have 2 questions:

How do you stop a php script from erasing the form fields when you do the submit? I’ve searched many posts here, most regarding JS which I’m not using. I’ve tried auto-complete=”new-password” but that didn’t appear to work. I would like the form data to remain after a submit so that if it needs to be updated the user doesn’t need to re-enter everything. Here’s a sample of what I mean:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="">


<meta charset="UTF-8"></meta>
<meta name="viewport" content="width=device-width, initial-scale=1.0"></meta>




<form method="post">

<label for="sometext"></label>
<input type="sometext" id="sometext" name="sometext" />

<button name="save">Save File</button>


        $text = $_POST['sometext'];
        $file=fopen("myfile.txt", "w");
        fwrite($file, $text);



Just what is that ‘/’ at the end of an input, for example the input line in the attached code?
