You need at most 2 queries with paganation.  You have way more than that, and are even running queries inside a foreach() loop.  I've changed the page a good bit, you may want to run this script without over writing your current page. 

 

class.pagAnate.php

class pagAnate {

private $numberPerPage;

private $sql;
public $page;
private $count;
private $numberOfPages;
public $PageNav;
public $limit;

function __construct($sql, $perPage, $url = NULL) {
	$this->page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
	$this->numberPerPage = $perPage;
	$this->url = $url;  //sets the first part of the url, ONLY if you are using mod_rewrite.
	$this->sql = $sql;
	$this->getPages();
}

private function getPages() {
	if(isset($this->sql)) {
		$q = mysql_query($this->sql);
			if(mysql_num_rows($q) > 0) {
				$r = mysql_fetch_row($q);
				$this->count = $r[0];				
			}
	}

	if(isset($this->count)) {
		$this->numberOfPages = ceil($this->count/$this->numberPerPage);

	}

	$this->setPageNumber();
}

private function setPageNumber() {
	$this->page = ($this->page > $this->numberOfPages) ? $this->numberOfPages : $this->page;
	$this->page = ($this->page < 1) ? 1 : $this->page;

	$this->setLimit();
}

private function setLimit() {
	$this->limit = 'LIMIT ' .($this->page - 1) * $this->numberPerPage .',' .$this->numberPerPage;

	$this->setNav();
}

private function setNav() {
	$this->url = ($this->url == NULL) ? '?page=' : $this->url . '/page/';
	if($this->count > $this->numberPerPage) {
		$nav = ($this->page == 1) ? ' FIRST    PREV '."\n" : '<a href="' . $this->url . '1">FIRST</a>    <a href="' . $this->url . ($this->page - 1) . '">PREV</a>' . "\n";
		$nav .= ' ( Page ' . $this->page . ' of ' . $this->numberOfPages . ' ) ';
		$nav .= ($this->page == $this->numberOfPages) ? " NEXT    LAST " :  '<a href="' . $this->url . ($this->page + 1) . '">NEXT</a>    <a href="' . $this->url . $this->numberOfPages . '">LAST</a> ';
		$this->PageNav = $nav;
	}
	else {
		$this->PageNav = NULL;
	} 		
}
}

Number of pages:

$numberOfPages = ceil($record_count / $per_page);

 

Calculate start:

$pageNumber = $_GET['page'];
$startIndex = ($pageNumber - 1) * $per_page;

for ($i = $startIndex; $i < $record_count && $i < ($startIndex + $per_page); ++$i) {
  //..
}

 

@jcbones does that code contain fragments from my Paginator class I posted here a few times?

I hope not, I wrote that myself about a year ago.  Although, I looked at around 1,000 (it seems) paganate scripts before I got my head wrapped around it.  So if something is similar, I'm sorry.  Not intentional in the least.

 

But, I would like to see it, have a link?

Ok sorry, i completely didnt understand last night what todo ive done it but i get this error on search.php

 

Parse error: syntax error, unexpected $end in C:\xampp\htdocs\site\scripts\class.pagAnate.php on line 3

 

as u can see the path to class.paganate is different but its include scripts/class.paganate in search.php so its all good.

copying code from here is weird, if you was to code it yourself thur would be loads of lines but as you can see theirs not im going to try a different text editor but please reply for quick fix.
