I am trying to accomplish two things with the code below:
1. Make the output display using an adjustable variable for the html table. output: ex: a variable of $tr=4 would display 4 rows of images, instead of a single row of images that I need to scroll across the page to view.
2. I want to create a new page dynamically (on the fly) for each of the images that are echoed out to the page. This will basically show a larger image and more details from the database.
Here's what I am using so far (all the code below works - just needs further adjusting for what I have asked above.)
Side note: Lines 1 - 132 = Pagination Code Side note: Lines 138 - 201 = Image Resize Code
<?php
include('config.php');
// Begin Pagination Code //
$tbl_name="ap_form_1"; //your table name
// How many adjacent pages should be shown on each side?
$adjacents = 1;
/*
First get total number of rows in data table.
If you have a WHERE clause in your query, make sure you mirror it here.
*/
$query = "SELECT COUNT(*) as num FROM $tbl_name";
$total_pages = mysql_fetch_array(mysql_query($query));
$total_pages = $total_pages[num];
/* Setup vars for query. */
$targetpage = "index.php"; //your file name (the name of this file)
$limit = 5; //how many items to show per page
$page = $_GET['page'];
if($page)
$start = ($page - 1) * $limit; //first item to display on this page
else
$start = 0; //if no page var is given, set start to 0
/* Get data. */
$sql = "SELECT * FROM $tbl_name ORDER BY ABS(`element_4`) DESC LIMIT $start, $limit";
$result = mysql_query($sql);
/* Setup page vars for display. */
if ($page == 0) $page = 1; //if no page var is given, default to 1.
$prev = $page - 1; //previous page is page - 1
$next = $page + 1; //next page is page + 1
$lastpage = ceil($total_pages/$limit); //lastpage is = total pages / items per page, rounded up.
$lpm1 = $lastpage - 1; //last page minus 1
/*
Now we apply our rules and draw the pagination object.
We're actually saving the code to a variable in case we want to draw it more than once.
