Simple problem requiring help

Hey, I am new to this forum and thought I would join as this seems to be a good place for problem solving/learning.

I have recently started learning php and mysql (basic) I have already run into a problem..

problem: I have created a database which i was using to test a simple login system. the error i get is:

Warning: mysql_num_rows() expects parameter 1 to be resource, object given in C:\xampp\htdocs\test.php on line 8

I do not know what i am doing wrong but the method im using is search the database for matching username & password, find if any rows are returned if so then login successful else wrong login.

<?php

 

$cxn = mysqli_connect("","root","","loginsystem");

$query= "SELECT name FROM user WHERE login='user' AND password='password'";

$result = mysqli_query($cxn,$query) or die("error");

// works from here

 

$n = mysql_num_rows($result);

 

echo $n;

 

 

?>

any help will be appreciated!

You can't mix mysqli_* and mysql_* functions . . .

Thank you, problem was solved I just changed the mysql_num_rows to mysqli_num_rows
