Search Facility Not Working

imatt · February 22, 2015

I am working on a database site with a search facility. At the moment all of our courses are listed in alphabetical order on this page (code shown below) with search facility at the top. However when we put in a criteria and click search it just returns a page with no courses listed....please help!

I have pasted the code for the page we get redirected to below the first code.

<?php 
include("admin/inc/db.php");
session_start();
include("header.php");
$q=$_SESSION['user_id'];
$user_type= $_SESSION['user_type'];
$sql1 = "SELECT * FROM `wp_provider_cource` where status='1'"; 
$query1= mysql_query($sql1);
$count1= mysql_num_rows($query1);

<?php 
//////////////  QUERY THE MEMBER DATA INITIALLY LIKE YOU NORMALLY WOULD

//////////////////////////////////// Adam's Pagination Logic ////////////////////////////////////////////////////////////////////////
$nr = mysql_num_rows($sql); // Get total of Num rows from the database query
if (isset($_GET['pn'])) { // Get pn from URL vars if it is present
    $pn = preg_replace('#[^0-9]#i', '', $_GET['pn']); // filter everything but numbers for security(new)
    //$pn = ereg_replace("[^0-9]", "", $_GET['pn']); // filter everything but numbers for security(deprecated)
} else { // If the pn URL variable is not present force it to be value of page number 1
    $pn = 1;
}
//This is where we set how many database items to show on each page
$itemsPerPage = 6;
// Get the value of the last page in the pagination result set
$lastPage = ceil($nr / $itemsPerPage);
// Be sure URL variable $pn(page number) is no lower than page 1 and no higher than $lastpage
if ($pn < 1) { // If it is less than 1
    $pn = 1; // force if to be 1
} else if ($pn > $lastPage) { // if it is greater than $lastpage
    $pn = $lastPage; // force it to be $lastpage's value

A completely blank page returned many times indicates a php failure. In development mode you should ALWAYS have php error checking turned on so you can monitor errors in your code and fix them. Try that. (see my signature)

It looks like you're using $query in your SELECT query without actually initializing the variable or setting any value to it. Turning on error reporting as ginerjm suggests will tell you if that's the issue.
