Adding previous(back) and next buttons next to the page numbers PHP - php

Question

I have two tiny little problems;
1 . I want to add a previous / next button into this code
2 . I want it to only show like max 10 links between previous and next. So if i have 50 numbers/links it will only show 10 of them and not 50 links on the page.
I have searched on the clo
The code works, only need that two options in it.
Can someone help me out? Thank you !
<?php
include 'includes/connection.php';
$per_page = 8;
$pages_query = mysql_query("SELECT COUNT(`id`) FROM `products`");
$pages = ceil(mysql_result($pages_query, 0) / $per_page);
$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$start = ($page - 1) * $per_page;
$query = mysql_query("SELECT `name` FROM `products` LIMIT $start, $per_page");
while ($query_row = mysql_fetch_assoc($query)) {
echo '<p>', $query_row['name'] ,'</p>';
}
if ($pages >= 1 && $page <= $pages) {
for ($x=1; $x<=$pages; $x++) {
//echo $x, ' ';
echo ($x == $page) ? '<strong>'.$x.'</strong> ' : ''.$x.' ';
}
}else{
header("location:index.php?page=1");
}
?>

Answer 1

First of all, you should, just for good practice, put an "exit;" after the header() call at the end. It doesn't make a difference in this particular script, but keep in mind that any code following a header("Location: ...") call WILL be executed before redirection.
Now to your question, try this (UPDATE: This code has been tested and works.)
<?php
include 'includes/connection.php';
$per_page = 8;
$pages_query = mysql_query("SELECT COUNT(`id`) FROM `products`");
$pages = ceil(mysql_result($pages_query, 0) / $per_page);
$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$start = ($page - 1) * $per_page;
$query = mysql_query("SELECT `name` FROM `products` LIMIT $start, $per_page");
while ($query_row = mysql_fetch_assoc($query))
{
echo '<p>' . $query_row['name'] . '</p>';
}
// If the requested page is less than 1 or more than the total number of pages
// redirect to the first page
if($pages < 1 || $page > $pages)
{
header('Location: ?page=1');
// end execution of the rest of this script
// it will restart execution after redirection
exit;
}
// If more than one page, show pagination links
if($pages > 1)
{
$html = array();
$html[] = '<strong>';
// if you're on a page greater than 1, show a previous link
$html[] = (($page > 1) ? 'Previous ' : '');
// First page link
$pageFirst = '1';
$html[] = (($page == 1) ? "</strong>{$pageFirst}<strong>" : $pageFirst);
if ($pages > 6)
{
$start_cnt = min(max(1, $page - (6 - 1)), $pages - 6);
$end_cnt = max(min($pages, $page + 4), 8);
$html[] = ($start_cnt > 1) ? '...' : ' ';
for ($i = $start_cnt + 1; $i < $end_cnt; $i++)
{
$html[] = ($i == $page) ? '</strong>' . $i . '<strong>' : '' . $i . '';
if ($i < $end_cnt - 1)
{
$html[] = ' ';
}
}
$html []= ($end_cnt < $pages) ? '...' : ' ';
}
else
{
$html[] = ' ';
for ($i = 2; $i < $pages; $i++)
{
$html[] = ($i == $page) ? '</strong>' . $i . '<strong>' : '' . $i . '';
if ($i < $pages)
{
$html[] = ' ';
}
}
}
// last page link
$pageLast = '' . $pages . '';
$html[] = (($page == $pages) ? "</strong>{$pageLast}<strong>" : $pageLast);
// Show next page link if you're on a page less than the total number of pages
$html[] = ($page < $pages) ? ' Next' : '';
// If you're not on the last page, show a next link
$html[] = '</strong>';
}
else
{
// show page number 1, no link.
$html[] = '<strong>1</strong>';
}
echo implode('', $html);
Also note that the final ?> is not required in PHP files that do not have HTML code following the PHP code, so I left it off.
