Hey guys needed alittle help here on my script.

The scripts reads all graphics in a chosen folder and then it shows the page with Previous and Next page buttons . I couldnt successfully make it add numbers in between them like Prev 1 2 3 ... Next

etc..

 

here is the code thanks in advance...

Pagination output is near bottom of code

 

<?
require_once( ROOT_DIR ."/include/db.php");
$title = $desc = $pagename = "Graphics Gallery";
$layout = "content";

?>
<script type="text/JavaScript">
<!--
function MM_jumpMenu(targ,selObj,restore){ //v3.0
  eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'");
  if (restore) selObj.selectedIndex=0;
}
//-->
</script>



    

<table width="100%">
  <tr>
    <td><div align="center"><h1>Browse Folders</h1>

// END OF CONFIGURATION SECTION
// Do not edit below this line

// Folder support
if(isset($_GET['folder']))
{
$cat .= $_GET['folder'] . '/';
$urlpath .= $_GET['folder'] . '/';
}

$hook = opendir($cat) or die('cant open dir');
$total = 0;

if(!isset($_GET['page'])) $page = 1;
else $page = $_GET['page'];

$start = $max2show * $page - $max2show;
$end = $page * $max2show;

/* folder support */
$directories = array();
/* End folder support part */

$ext = array("jpg", "png", "jpeg", "gif");
while (false!==($file = readdir($hook))) {
$idnum = "1";
// Functionality to check folders added here

if(is_dir($fpath))
{
  //echo 
	if($file != '.' && $file != '..')

Hmmm.... Best advice is to use a Database unless you use __Line__ in front of every line and call it with PHP and use something like:

 

<?php
if (__line__ >= 60){
#code here
}
elseif (__line__ >= 120){
#code here
}
// Ect... Ect... Ect...
?>

 

Is there some reason why you cant use a database because if you can use one. Everything I do is always hosted on some type of database somewhere

Post a snippet of code that you are trying to paginate.  I successfully paginated a text file using pointers inside the file, I used preg_match to get the info between the pointers and displayed it, for the numbers, I read how many pointers there were, printed the previous code, did a foreach loop to print the numbers, then printed the next code.

Hey ok i edited the code so that you can test it on your server create a folder called graphictest in your web root. then edit these 2 variables at top to reflect it

 

$urlpath = "http://domain.com/graphicstest";

$cat = "/home/username/public_html/graphicstest";

 

then after upload this script in that folder create a folder inside of that test folder and add some graphics and you will see what i mean .. Thanks
