How to compare two input variables with mysql stored values (PHP)? -

-

I'm basically wanted to make an HTML form in which the user puts two different input then this information in a MySQL table Compiled data is compared with. If both of the input variables match the two variables in the same row from the table, it gives a message, if it does not give another, how can I do it? This is my code so far:

if (mysqli_connect_errno ()) { echo "failed to connect to MySQL:". Mysqli_connect_error (); }

Escape Wheriabls

For security //

$ numero_cedula = mysqli_real_escape_string ($ to, $ _POST [ 'numero_cedula']); $ codigo = mysqli_real_escape_string ($ con, $ _POST ['codigo']);

$ sql1 = "select Numero Cedula Numero Sedula = $ numero_cedula";

mysqli_query ($ conn, $ sql1);

$ Sql2 = "Select from Codigo where the tester is codego = $ codigo";

Micli_kweri ($ why, $
