Hi can anyone take a look at my code and tell me why the while() loop isn't working?
PHP Code:
<?php
session_start();
//check to make sure the session variable is registered//the session variable isn't registered, send them back to the login page
if(!session_is_registered('username')){ header("Location:login.php");}
require_once('Connections/tst.php');
// Sets how many results shown per page
$limit = 25;
// Sets what we want to pull from the database
// count(*) is better for large databases
$query_count = "SELECT count(*) FROM students";
// Pulls what we want from the database
$result_count = mysql_query($query_count);
// This counts the number of users
$totalrows = mysql_num_rows($result_count);
if(empty($page)){ // Checks if the $page variable is empty
$page = 1; // If it is empty, we're on page 1
}
$limitvalue = $page * $limit - ($limit);
//Query to pull info for the students and the organization name
$query = "SELECT students.fname, students.lname, students.email, students.phone1, organization.name AS company FROM students LEFT JOIN organization ON students.organization_id = organization.organization_id LIMIT {$limit}";
$result = mysql_query($query);
if(!$result) {
echo "Problem loading students from the database.".mysql_error();
exit();
}
?>

} else {

}
$numofpages = $totalrows / $limit;
for($i = 1; $i <= $numofpages; $i++){
if($i == $page){
echo($i." ");
}else{
