This is why ...

if(empty($name)){  

echo "+ Name Required!<br/>";  

}else if(empty($pwd)){  

echo "+ Password Required!<br/>";  
}  
else{ 

Replace

if(empty($_REQUEST[name])){  

echo "+ Name Required!<br/>";  

}else if(empty($_REQUEST[pwd])){  

echo "+ Password Required!<br/>";  
}  
else{
