[RESOLVED] Conditional Statement Help

focus310

Hello:

I'm trying to write an "if" statement which tests two variables using an OR.

The should be:
if fico or ficonum is less than 680 - go to index.html page
else if
fico or ficonum is greater or equal to 680 - to to details_costs.php page.

When I run the script and test for both conditions I am brought to the index.html page. When I type in a number of 720 (which is greater than 680) I'm brought to index.html not details_costs.php. I am not sure why this is happening.

The reason for fico and ficonum are the following. Some people may not know their score so "fico" assigns a value to "Excellent" being 730, "Good" being 700, etc. Others may know their score so "ficonum" is the actual score the person types. A person uses one of the two not both.

To check logical conditions I thought one usess || for OR, < for less than, and >= for greater or equal. Can someone help me out?

Thank you in advance.

This is my statement:

if (($_SESSION['fico'] || $_SESSION['ficonum'] < 680)) {
    include('index.html');
  } elseif 
    (($_SESSION['fico'] || $_SESSION['ficonum'] >= 680)) {
    include('details_costs.php');
  }

if ($_SESSION['fico']) $ficonum = $_SESSION['fico'];
else                 $ficonum = $_SESSION['ficonum'];
if ($ficonum < 680) include 'index.html';
else            include 'details_costs.php';

You have to test each variable:

if ($_SESSION['fico'] < 680 || $_SESSION['ficonum'] < 680) {
    include('index.html');
}
else {
    include('details_costs.php');
}

Hello:

I did test each variable. The result was successfull for each. When I put all four together then the result is not what it should be.

One of two things happens, either index.html gets displayed or the correct page gets displayed but then I get an undefined index for ficonum. The undefined index makes no sense since when I test it all by itself, the value goes through without a problem. When I test for fico, the message for undefined index appears.

I'm not sure how the OR condition is really working.

The undefined index is a different issue. Do this:

$ficonum = -666;
if (isset($_SESSION['fico']    && $_SESSION['fico']) $ficonum = $_SESSION['fico'];
if (isset($_SESSION['ficonum'] && $_SESSION['ficonum']) $ficonum = $_SESSION['ficonum'];
if ($ficonum == -666) die('Neither was set');

if ($ficonum < 680) include 'index.html';
else            include 'details_costs.php';

This does not check each variable to see if it's less than 680:

if (($_SESSION['fico'] || $_SESSION['ficonum'] < 680)) {

What it actually does is check to see if $SESSION['fico] has a non-zero value OR if $SESSION['ficonum'] is less than 680. You therefore have to apply the "< 680" to both variables, as per my example code:

if ($_SESSION['fico'] < 680 || $_SESSION['ficonum'] < 680) {
//                    ^^^^^                         ^^^^^

Thanks for the help. I finally got the statement to work.
