I'm working on a project and encountering an issue with an undefined variable in my HTML code. I'm fairly new to HTML, so I would appreciate some help with this problem.
I'm receiving an error message that says "Undefined variable: username in C:\xampp\htdocs\test.php on line 26." From what I understand, it seems like I haven't declared the variable 'username' properly in my code.
To provide some context, I'm trying to create a simple login form where users can enter their username and password. Here's a snippet of the code that's causing the issue:
<form action="login.php" method="POST">
<input type="text" name="username" id="username">
<input type="password" name="password" id="password">
<input type="submit" value="Login">
The error specifically points to line 26, but I can't seem to figure out what's wrong with this code. I've double-checked and made sure that the variable 'username' is used consistently throughout my code, so I'm not sure where I went wrong.
Could someone please help me understand why I'm getting this undefined variable error? Any guidance or suggestions to resolve this issue would be greatly appreciated.
Thank you in advance!
