Numbered Pagination Using MySQLi

Tutorial created by Jamie, Motley.co.uk

Categories: MySQLi Server Behaviors, PHP

rating

A simple method using a MySQLi recordset to be able to use numbered pagination .

arrow downStep 1 - Add the MySQLi recordset

The recordset is based on a table named 'news' in the database. You can configure to whatever table name you wish.

The code in line 1 of the recordset $maxRows_News =10 is returning 10 items from the database per page, you can change that to however many records you want to show per page.

<?php
$maxRows_News =10;
$News = new WA_MySQLi_RS("News",$DBConnection,$maxRows_News);
$News->setQuery("SELECT * FROM news");
$News->execute();

$NewsTotal = new WA_MySQLi_RS("NewsTotal",$DBConnection);
$NewsTotal->setQuery("SELECT count(1) a FROM news");
$NewsTotal->execute();
$News_Total = (int)$NewsTotal->Results[0]['a'];
$Req_Pages = ceil($News_Total/$maxRows_News);
?>

arrow downStep 2 - add the pagination code

Now just add the following code to the area of your page that you wish the pagination to appear:

<?php

$totalRows_News = $News_Total;

$pageNum_News = 0;
if (isset($_GET['pageNum_News'])) {
$pageNum_News = $_GET['pageNum_News'];
}

$incdone = false;
if ($maxRows_News == 0)
{
$maxRows_News =1;
$incdone = true;
}

$totalPages_News = ceil($totalRows_News/$maxRows_News)-1;


if($totalPages_News > 0 && !$incdone )
{
$elems = array();
for ($i=0;$i<$Req_Pages;$i++)
{
if ($i==$pageNum_News)
{

$elems[] = "<b>".($i+1)."</b>";
}
else
{
$elems[] = "<a href=\"news.php?pageNum_News=$i\">".($i+1)."</a>";
}
}

echo implode(" | ",$elems);
}
?>

I am getting a error { Fatal error: Class 'WA_MySQLi_RS' not found in records.php on line 4 }

I am using Wampserver 2.5 With apache 2.4.9, PHP 5.5.12, MySQL 5.6.17 I know that this version will not work with MySQL but it will work with MySQLI but evidently it dos not have the WA_MySQLi_RS Class in it. can you help?

Hi

I have used this one of my websites and it does the job very nicely. Thank you.

However I have a small problem which is beyond my coding knowledge.

If I use a filter on the listing (eg " ... FROM items WHERE items.furtherAttention LIKE 'Y%' ORDER BY ...") it reduces the number of records to be paginated - and this causes problems.

I'd be grateful for any assistance.

Thanks

Andrew

I dont see where the offset is set. How are you telling it what page you are currently on?

mike404055: 1 Year, 3 Months, 2 Weeks, 8 Hours, 22 Minutes ago

I've used this code and it works perfectly with the MySQLi extension, however it returns 128 pages with numbers in my case, which is far too long to use. How can I truncate the numbers so that only some are showing at any time? Someting like 1 2 3 4 5 6 7 8 9 10... 128 etc.

Many thanks,
Mike

Great tutorial. I have same Qs as Andrew and Mike. What if recordset is filtered and showing fewer than all pages, and how to truncate list of numbers if pages is more than 10, for ex. ( 1|2|3|4|5 ... 24 )

I'll check forum to see if answers might lie there.

Thanks!

Hi,
for all of you who asking how to use the pagination when filtering the query just do the following

REPLACE AFTER THE FROM PART
$NewsTotal->setQuery("SELECT count(1) a FROM news");
WITH WHAT YOUR INITIAL QUERY ACTUALLY FILTERS

SO FOR EXAMPLE IF YOU ACTUAL QUERY IS
SELECT products.ProductID, products.ProductSKU, products.ProductName, products.product_cat, products.product_collection_fgn_id, products.product_material_fgn_id, products.ProductPrice, products.product_on_discount, products.ProductRetailPrice, products.prroduct_on_retail_discount, products.ProductThumb, products.ProductImage, products.product_order, collections.collection_name, product_categories.product_category_name FROM products INNER JOIN collections ON products.product_collection_fgn_id = collections.collection_id INNER JOIN product_categories ON products.product_cat = product_categories.product_category_id WHERE products.product_collection_fgn_id = ? AND products.product_cat = ? ORDER BY products.ProductID DESC, products.product_order ASC, products.ProductName ASC"

TAKE THE FROM PART
FROM products INNER JOIN collections ON products.product_collection_fgn_id = collections.collection_id INNER JOIN product_categories ON products.product_cat = product_categories.product_category_id WHERE products.product_collection_fgn_id = ? AND products.product_cat = ?
AND PASTE IT INSIDE THE
$NewsTotal->setQuery("SELECT count(1) a FROM news");

SO YOUR FINAL QUERY SHOULD BE
$NewsTotal->setQuery("SELECT count(1) a FROM products INNER JOIN collections ON products.product_collection_fgn_id = collections.collection_id INNER JOIN product_categories ON products.product_cat = product_categories.product_category_id WHERE products.product_collection_fgn_id = ? AND products.product_cat = ?");

Just don't forget to place the filtering variables at the end
$getAllProducts->bindParam("i", "".$_GET['col'] ."", "-1"); //WAQB_Param1
$getAllProducts->bindParam("i", "".$_GET['cat'] ."", "-1"); //WAQB_Param1


Thank you.

PS I used a more complex query (more filters) to show you that it can work with as many filters as you like

Nico: 7 Months, 3 Weeks, 5 Days, 13 Hours, 5 Minutes ago

Just a correction to my previous post
The variables should be like this
$NewsTotal->bindParam("i", "".$_GET['col'] ."", "-1"); //WAQB_Param1
$NewsTotal->bindParam("i", "".$_GET['cat'] ."", "-1"); //WAQB_Param1
