how to convert MySQL to MySQLi

[9pleum]

Convert this

return (mysql_result($total, 0) == '1') ? true : false;

to MySQLI ?

Need to see the query for it. Based on the ternary operator, you could probably use mysqli_num_rows();

Well, if you wanna use MySQLi you'd have to change it throughout your code, not just on one line.

Here's an introduction to MySQLi.

[9pleum]

function valid_credentials($user, $pass){
	global $mysqli;
	$user = $mysqli->real_escape_string($user);
	$pass = $mysqli->real_escape_string($pass);
	
	$total = $mysqli->query("SELECT COUNT(`user_id`) FROM `users` WHERE `user_name` = '{$user}' AND `user_password` = '{$pass}'");
	
	return (mysql_result($total, 0) == '1') ? true : false; 
}

i don't understand this line ;'c

return (mysql_result($total, 0) == '1') ? true : false;

you need to fetch that line through mysqli

$total = $mysqli->query("SELECT COUNT(`user_id`) FROM `users` WHERE `user_name` = '{$user}' AND `user_password` = '{$pass}'");
$row = $total->fetch_row();
return ($row[0] == 1) ? true : false;

Ohh, thank you

Here's something that helped me when I decided to use MySQLi over MySQL, I hope it'll help you and other users.

$cxn is the connection variable.

If you want a function that's not in the image then just search for it in the PHP Docs and you'll see a warning saying MySQL is deprecated linking to the exact MySQLi and PDO function.

That is actually pretty useful. Neat table.
Wish I had that back when..
