The code below won't work directly since it's for MSSQL (Microsoft SQ)
Just replace those 's with `s and change the SqlCommand, SqlDataReader to whatever they're called for MySQL.
PHP Code:
public static bool VerifyLogin(string Username, string Password)
{
if (ConnectionOpen)
{
SqlCommand SQLCommand = new SqlCommand("SELECT * FROM Accounts WHERE Username='" + Username + "' AND Password='"+Password+"'", SQLConnection);
SqlDataReader DataReader = SQLCommand.ExecuteReader();
return DataReader.HasRows;
}
return false;
}
