Paginator help - displays ALL records
Posted: Mon Jun 14, 2010 7:56 pm
I'm trying to add the Paginator script to my web page and it's almost there BUT it's bringing up all the records from my database instead of the select number of records. I'm posting my PHP code below (purposely leaving out my MySql connections), then I've attached the PHP reference file: paginator.class.php that's referenced in the code.
Thanks for your help!
Here are the details for the paginator.class.php file:
Thanks for your help!
Code: Select all
<?php
include('paginator.class.php');
$mysqli = mysqli_connect("", "", "", "");
if (mysqli_connect_errno()) {
printf("Connect falied: %s\n", mysqli_connect_error());
exit ();
} else {
$sql = "SELECT * FROM product";
$res = mysqli_query($mysqli, $sql);
$num_rows = mysqli_fetch_array($res);
$pages = new Paginator;
$pages->items_total = $num_rows[0];
$pages->mid_range = 9; // Number of pages to display. Must be odd and > 3
$pages->paginate();
if ($res) {
while ($newArray = mysqli_fetch_array($res, MYSQLI_ASSOC)) {
$detail = $newArray['id'];
$photo = $newArray['photo'];
$id = $newArray['title'];
$price = $newArray['price'];
list($width) = getimagesize($photo);
// set the maximum width of the image here
$maxWidth = 100;
if ($width > $maxWidth)
echo "<p><a href=\"painting.php\"><img alt=\"Image\" width=\"{$maxWidth}\" src=\"{$photo}\" /></a>";
