Users Login with Multiple permission levels via SQL
I want user login with Multiple permission levels, My SQL has Perm_type column
I want when Perm_type is 1 show Administrator, Perm_type is 2 show Staff
I don't know how to add code to check Perm_type
My Code is
public Login_form()
{
InitializeComponent();
/*initialize connection*/
con = new MySqlConnection("Server=localhost;Database=demo;user=demouser;Pwd=demopassword;SslMode=none");
}
private void Login_btn_Click(object sender, EventArgs e) //Log In Button
{
string user = id_txt.Text;
string pass = Pwd_txt.Text;
cmd = new MySqlCommand();
con.Open();
cmd.Connection = con;
cmd.CommandText = "SELECT * FROM demo_login where id='" + id_txt.Text + "' AND password='" + Pwd_txt.Text + "'";
dr = cmd.ExecuteReader();
if (dr.Read())
{
Administrator new_Form = new Administrator();
new_Form.Show();
}
else
{
MessageBox.Show("Invalid Login please check username and password");
}
con.Close();
}
c# mysql login

Never glue bits of string together to make a SQL query - use SQL Parameters always. Never ever store passwords as plain text - salt and hash them.
