The post value cannot be obtained. how can this problem be solved?

The value of post cannot be obtained & lt; forw.hod = & quot; post & quot; action = & quot; http: // localhost/secret. php & quot; & gt; & nbsp; & lt; tableborder = & quot; 1 & quot; The post value cannot be obtained.

Why can't I upload the name and password to secret. php for a beginner?
// Secret. php
// Create short names for variables
If ($ _ POST ['name'] = ''& $ _ POST ['password'] = '')
{
// Visitor need to enter a name and password
Echo 'Please input an valid username and password ';
}
Elseif ($ _ POST ['name'] = 'root' & $ _ POST ['password'] = '000000 ')
{
Echo 'Welcome to the New World! ';
}
Else
{
Echo 'You are not welcome! ';
}
?>

------ Solution --------------------
The name attribute needs to be added to the input control. The browser will submit the value to the server only in this way.
