Question

I have a logic error I cannot for the life of me figure out. The problem is this very very basic login page I have written is always outputting the default answer as opposed the the choice from the table.

I am trying to return to the php the value in E_Type in this case the value should return A, however it is not.

What am I doing wrong?

Code:

<?php
$server   = -Removed;
$login    = -Removed;            
$pass     = -Removed;        
$login    = $_POST['login'];
$password = $_POST['password'];
$table    = 'USERPASS';
$table2   = 'EMPLOYEES';
$res      = 'q';

$dblink = @mssql_connect(-Removed) or die("Error 1");
mssql_select_db('group5', $dblink) or die( "unable to select the database");

$sqlquery = "SELECT E_TYPE FROM USERPASS U, EMPLOYEES E WHERE U.EMPLOYEE_ID = E.EMPLOYEE_ID AND PASSWORD = '$password' AND USERNAME = '$login'";
$res = mssql_query($sqlquery, $dblink) or die("Error5");
$count = mssql_num_rows($res);

if($count==1)
{
    if ($res == "A" )
    {
        echo "Success 1";
    }
    else if ($res == "B" )
    {
        echo "Success 2";
    }
    else
    {
        echo "Error...";
    }
}
?>

You need to fetch the result first. In $res you basically only have a result handle that can iterate over the results.

Use mssql_fetch_assoc to fetch the results and access them (this would loop over all resulting rows):

while(($row = mssql_fetch_assoc($res)) !== FALSE) {
    echo $row['E_TYPE'];
}

In your case (if you only expect a single row) use this:

if($count == 1) {
    $row = mssql_fetch_assoc($res);
    if ($row['E_TYPE'] == "A" )
    {
        echo "Success 1";
    }
    else if ($row['E_TYPE'] == "B" )
    {
        echo "Success 2";
    }
    else {
        echo "Error...";
    }

}
