Hi
I am trying to paginate search results but have the following error
Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, array given in /home/sites/it-doneright.co.uk/public_html/admin/software-sales/search-data.php on line 148
It is dividing up the results as 5 per page so that bit is working but unsure of what I am missing
below is my script
Thank you in advancePHP Code:<?php
ini_set('display_startup_errors',1);
ini_set('display_errors',1);
error_reporting(-1);
include('connect.php');
$per_page=5;
if (isset($_GET["page"])) {
$page = $_GET["page"];
}
else {
$page=1;
}
// Page will start from 0 and Multiple by Per Page
$start_from = ($page-1) * $per_page;
$data = [];
if (isset($_GET['d1']) && isset($_GET['d2'])) {
$d1 = strtotime($_GET['d1']);
$d2 = strtotime($_GET['d2']);
if ($d1 && $d2) {
$start_date = date('Y-m-d', $d1);
$end_date = date('Y-m-d', $d2);
$result = $db->prepare("SELECT * FROM purchased_software WHERE sales_month BETWEEN :a AND :b ORDER BY id LIMIT $start_from, $per_page");
$result->bindParam(':a', $start_date);
$result->bindParam(':b', $end_date);
$exec = $result->execute();
if ($exec) {
$data = $result->fetchAll();
}
}
}
