Well i have been working with a search page for my site. I have the search script in one file and pagination class in another file.
I can't figure out how to merge the two.
this is the search script
require_once ('db connection file'); // Connect to the database.
// Set up our error check and result check array
$error = array();
$results = array();
// First check if a form was submitted.
// Since this is a search we will use $_GET
if (isset($_GET['search'])) {
$searchTerms = trim($_GET['search']);
$searchTerms = strip_tags($searchTerms); // remove any html/javascript.
if (strlen($searchTerms) < 2) {
$error[] = "Search terms must be longer than 2 characters.";
}else {
$searchTermDB = mysql_real_escape_string($searchTerms); // prevent sql injection.
}
// If there are no errors, lets get the search going.
if (count($error) < 1) {
$searchSQL = "SELECT link, keywords FROM products WHERE ";
// grab the search types.
$types = array();
$types[] = isset($_GET['keywords'])?"`keywords` LIKE '%{$searchTermDB}%'":'';
$types = array_filter($types, "removeEmpty"); // removes any item that was empty (not checked)
if (count($types) < 1)
$types[] = "`keywords` LIKE '%{$searchTermDB}%'"; // use the body as a default search if none are checked
$andOr = isset($_GET['matchall'])?'AND':'OR';
$searchSQL .= implode(" {$andOr} ", $types) . " ORDER BY `keywords`"; // order by title.
$searchResult = mysql_query($searchSQL) or trigger_error("There was an error.<br/>" . mysql_error() . "<br />SQL Was: {$searchSQL}");
if (mysql_num_rows($searchResult) < 1) {
$error[] = "The search term provided {$searchTerms} yielded no results.<p><a href='contact-us.php'>If you are unable to find what you are looking for please click here to contact us</a>";
}else {
include ('includes/paginator.class.php');
$results = array(); // the result array
$i = 1;
while ($row = mysql_fetch_assoc($searchResult)) {
$results[] = " {$row['link']}<br />";
}
}
}
}
function removeEmpty($var) {
return (!empty($var));
}
and now the pagination script:
?php
class Paginator{
var $items_per_page;
var $items_total;
var $current_page;
var $num_pages;
var $mid_range;
var $low;
var $high;
var $limit;
var $return;
var $default_ipp = 10;
function Paginator()
{
$this->current_page = 1;
$this->mid_range = 7;
$this->items_per_page = (!empty($_GET['matchall'])) ? $_GET['matchall']:$this->default_ipp;
}
function paginate()
{
if($_GET['matchall'] == 'All')
{
$this->num_pages = ceil($this->items_total/$this->default_ipp);
$this->items_per_page = $this->default_ipp;
