PHP Pagination for MySQL posts - php

Question

I've been trying for hours to implement a pagination for a blog that I am working on, but I just can't find it to work. In the URL, it gives me (myurl).php?pageno=
Without the page number requested.
This is my page to handle the database request:
<?php
require_once("db-connect.php");
$offset = 0;
$page_result = 5;
if($_GET['pageno'])
{
$page_value = $_GET['pageno'];
if($page_value > 1)
{
$offset = ($page_value - 1) * $page_result;
}
}
$results = mysqli_query($connection, "SELECT * FROM blog where $condition ORDER BY date DESC LIMIT $offset, $page_result")
or die(mysqli_error('No Records Found'));
?>
This is my blog page code:
<?php
if (mysqli_num_rows($results) > 0) {
// output data of each row
while($row = mysqli_fetch_assoc($results)) {
echo "<li class='background-white'><div class='column large-4'><a href='".$row['link']."' class='text-black1' title='".$row["arttitle"]."'>"."<img src='http://tmggeotech.com/img/blog/".$row['thumbnail']."' alt='".$row['thumbalt']."'/>"."</a></div>"."<div class='column large-8 article-data'>"."<h4><a href='".$row['link']."' class='text-black1' title='".$row["arttitle"]."'>".$row["arttitle"]."</a></h4>"."<small class='text-black2'>Publicado el <span class='text-orange2'>".date('m/d/Y', strtotime($row['date']))."</span> | "."Categoría: <span class='text-orange2'>".$row["category"]."</span></small>"."<p>".$row["excerpt"]."</p>"."</div>"."</li>";
} }else {
echo "0 results";
}
$pagecount = 50; // Total number of rows
$num = $pagecount / $page_result;
if($_GET['pageno'] > 1) {
echo "Prev";
}
for($i = 1 ; $i <= $num ; $i++) {
echo "".$i."";
}
if($num != 1) {
echo "Next";
}
?>
So my question is:
Is it there something I am missing here to make it work?

Answer 1

Thanks to #ccKep for point out some clues on how to get what I needed. I just made it work.
In page to handle the database request, I added a second request but without LIMIT, so that I could use num_rows with it:
<?php
require_once("db-connect.php");
$offset = 0;
$page_result = 5;
if($_GET['pageno'])
{
$page_value = $_GET['pageno'];
if($page_value > 1)
{
$offset = ($page_value - 1) * $page_result;
}
}
$results = mysqli_query($connection, "SELECT * FROM blog where $condition ORDER BY date DESC LIMIT $offset, $page_result")
or die(mysqli_error('No Records Found'));
$npages = mysqli_query($connection, "SELECT * FROM blog where $condition ORDER BY date DESC")
or die(mysqli_error('No Records Found'));
?>
Later, on my blog page I round up my posts to the next multiple of 5 number.
And also changed my last if statement so that the NEXT button disappears after getting the last page.
<?php
if (mysqli_num_rows($results) > 0) {
// output data of each row
while($row = mysqli_fetch_assoc($results)) {
echo "<li class='background-white'><div class='column large-4'><a href='".$row['link']."' class='text-black1' title='".$row["arttitle"]."'>"."<img src='http://tmggeotech.com/img/blog/".$row['thumbnail']."' alt='".$row['thumbalt']."'/>"."</a></div>"."<div class='column large-8 article-data'>"."<h4><a href='".$row['link']."' class='text-black1' title='".$row["arttitle"]."'>".$row["arttitle"]."</a></h4>"."<small class='text-black2'>Publicado el <span class='text-orange2'>".date('m/d/Y', strtotime($row['date']))."</span> | "."Categoría: <span class='text-orange2'>".$row["category"]."</span></small>"."<p>".$row["excerpt"]."</p>"."</div>"."</li>";
} }else {
echo "0 results";
}
$x = ceil($npages->num_rows/5) * 5;
$pagecount = $x; // Total number of rows
$num = $pagecount / $page_result;
if($_GET['pageno'] > 1) {
echo "<a href='noticias-perforacion-suelos-articulos-maquinas-blog.php?pageno=".($_GET["pageno"] - 1)."'>Prev</a>";
}
for($i = 1 ; $i <= $num ; $i++) {
echo "<a href='noticias-perforacion-suelos-articulos-maquinas-blog.php?pageno=".$i."'>".$i."</a>";
}
if($_GET['pageno'] == $num) {
echo "";
} else {
echo "<a href='noticias-perforacion-suelos-articulos-maquinas-blog.php?pageno=".($_GET["pageno"] + 1)."'>Next</a>";
}
?>
You might notice that I am not a very good coder, so if you find a less messy way to do this please let me know.
Cheers!
