Hello,

after almost two hours trying to understand where is the error, I am getting sick with the code and I hope someone here can help me.

I need to make a simple query and return the value, to check if user and password is ok. But my function only returns -1

I checked the table, fields, connections and all is ok. Where is the error:

this is my function

function login_sistema($uso, $senha){
	
    global $servername, $username, $password, $dbnome;
	
	// Create connection
	$conn = new mysqli($servername, $username, $password, $dbname);
	// Check connection
	if ($conn->connect_error) {
		die("Connection failed: " . $conn->connect_error);
	} 
		
	$sql = " SELECT * FROM CADUSO ";
	$sql = $sql . " WHERE NOME='" .$uso . "'";
		  
    $rs= $conn->query($sql);  
	

    if ($rs->num_rows > 0) {	
		if ($row("senha")==$senha){
			$id = 1;
		} else {
			$id = -2;
		}		 		
	} else {   
		$id = -1;		
	}		
   
    $conn->close();
    return $id;		
}	 

Thanks a lot
Alex
