Please dont use the code below!
It wasn't deleted just for your references.

This is replacement for the default /includes/paging.php that works exactly the same but could be used for anything, not only for images. (If u are not gonna do your own changes in 4images code, then probably dont bother reading "How To Use" section ;))


1. Backup original /includes/paging.php
2. Create new /includes/paging.php file with this code (replace the original)
Code: [Select]

    return $this->desc;
  }
//end of class
?>

I added alternative way to show number of pictures (reference)
for that u'll need just change $this->alt = 1; inside the file.


How To Use:
I'll try explain by an example ;):
Code: [Select]
  $cat_num_all = 10;
  $cat_perpage = 4;
  $cat_page = 2;
  $link_arg = $site_sess->url(ROOT_PATH."categories.php");
  $text = "Found {total_cat_images} categories(s) on {total_pages} page(s) .Displayed: category {first_page} to {last_page}.";
  $page_text = "cat_page";
  $extra = "categories";
  include(ROOT_PATH.'includes/paging.php');
  $getpaging = new Paging($cat_page, $cat_perpage, $cat_num_all, $link_arg, $text, $page_text, $extra);
  $offset = $getpaging->get_offset();
  $site_template->register_vars(array(
    "cat_paging" => $getpaging->get_paging(),
    "cat_paging_stats" => $getpaging->get_paging_stats()
  ));
this is not working example, so dont bother trying it ;)

if u are familuar a little bit with 4images code, then u might see, that all this is almost the same as the default, exept three new variables that being send to Paging class:
$getpaging = new Paging($cat_page, $cat_perpage, $cat_num_all, $link_arg, $text, $page_text, $extra, $style);
if u leave those variables empty (or just wont add them to the code), paging will use the default settings.

In $text variable u can specify text that u'd like to show in the templates by {cat_paging_stats}
U can use the same {..} tags as in $lang['paging_stats'] in your /lang/<yourlanguage>/main.php

In $page_text u can specify name of "page" for the link address. In this example it will change current page when in the address add cat_page=XX . If u leave it empty it will generate links to the pages by using page=XX. This is neccery if u want use more then one paging at the same page, for example if u want add paging for list of categories and still have paging for images.

$extra needs only if u want after open "next" page it "jumps" to the part of page, name of witch matching with $extra. $extra will be added into "pages" link as #$extra.
in this example the link would be:
categories.php?cat_page=XX#categories

$style set style of paging displayed. If not set, will use class="paging"

Hi V@no ,

I want to use your paging class in my news

this my code news
Code: [Select]
$sql = "SELECT * FROM ".NEWS_TABLE." ORDER BY id DESC ";
   $result = $site_db->query($sql);
   $num_rows = $site_db->get_numrows($result);
   $archive_row = array();

   while ($row = $site_db->fetch_array($result)) {
    $archive_row[] = $row;
}
   $site_db->free_result($result);


if (!$num_rows) {
     $news = "&nbsp;&nbsp;&nbsp;<b>NO MASAGE YET</b>";  
  }
  else {
  $news = "";
$bgcounter = 0;

   for ($i = 0; $i < $num_rows; $i++) {
      $row_bg_number = ($bgcounter++ % 2 == 0) ? 1 : 2;
         
         $site_template->register_vars(array(
 "id" => ($archive_row[$i]['id']),
"totalpage"=>$totalMsg,
"text" => convertBBCode($archive_row[$i]['text']),
"title" => ($archive_row[$i]['title']),
"date" => ($archive_row[$i]['date']),
"row_bg_number" => $row_bg_number));

          $news .= $site_template->parse_template("cpnews_detail");

Hi v@no,

I have problems with the paging.php...
I want different colors (styles) for different pagings - for example black text for category-paging and yellow text for news-archiv-paging.
My knowledge with php-classes isnīt good enough to mod the sourcecode.  :(  Can you help me?
My paging.php. is like yours.
pagingstuff from index.php:
Code: [Select]
 if ($newstype == "latestnewsall") {
    include(ROOT_PATH.'includes/paging.php');
    $perpage = $show_news_articles;
    $link_arg = $site_sess->url(ROOT_PATH."index.php?newstype=latestnewsall");
    $getpaging = new Paging($page, $perpage, $num_rows, $link_arg);
    $offset = $getpaging->get_offset();

    $site_template->register_vars(array(
      "paging" => $getpaging->get_paging(),
      "paging_stats" => $getpaging->get_paging_stats()
    ));

my archive.html:
Code: [Select]
                                 <td align="left"  class="head1" width="50%"><img src="{template_url}/images/spacer.gif" alt="" width="4" height="4" />Newsarchiv</td>
                                  <td align="right" class="head1" width="50%">{paging}<img src="{template_url}/images/spacer.gif" alt="" width="4" height="4" /></td>


As a non functioning example here my testsite:http://www.miss-magdeburg.de
thanks

ok, I just added support different style classes.
for example in categories.php u can use it like this:
Quote
$getpaging = new Paging($page, $perpage, $num_rows_all, $link_arg, "", "", "", "head1");
it will display paging with head1 style class (u'll need set all needed styles in your .css file.)

OK, I HOPE this is the mod I'm looking for :)

What I'm trying to do is change the Last Page and Next Page links on categories.php to graphical links instead of text links. To see what I mean, check out my details.php page:

http://photo.vandalized.org/details.php?image_id=44

I'd like to to be able to use the same setup on my categories.php pages. What would need to be changed in paging.php to allow for this?
