thanks! i was able to limit the number of catergories shown on my home.html page, but is there a way to add navigation for categories not shown on the home.html page? example: say i have 50 catergories and i want only 10 catergories diplayed on my home.html page. is there a way to add a link to the next page to display the next 10 catergories, etc.?

[V@no]

sorry, I dont think I understand your question.
This mod should affect home page as well as categories page....

[iraklis]

ok i read all the posts to this topic. i'm a little bit in disorder. i'm so far, that it shows the number of categories i want and the cat_paging. but i've still the problem  that i can't go to page number 2,3,4......

function.php looks like that

<sup>//Begin configuration:

$perpage = 3; //how many categories per page
$cat_text = "Found {total_cat_images} categories on {total_pages} page(s). Displayed category {first_page} to {last_page}";

//u can use those tags:
//{total_cat_images} - total categories
//{total_pages} - total pages
//{first_page} - displayed from (number first category displayed)
//{last_page} - displayed to (number last category displayed)
//End configuration

$page = (isset($HTTP_GET_VARS['cat_page'])) ? $HTTP_GET_VARS['cat_page'] : 0;
if (!class_exists(Paging)) {
include(ROOT_PATH.'includes/paging.php');
}
$link_arg = $site_sess->url(ROOT_PATH."categories.php?".URL_CAT_ID."=".$cat_id);
$getpaging = new Paging($page, $perpage, $total, $link_arg, $cat_text, "", "cat_page");
$offset = $getpaging->get_offset();
$limit = ($offset + $perpage > $total) ? $total : $offset + $perpage - 1;
$total = $limit - $offset;
$site_template->register_vars(array(
 "cat_paging" => $getpaging->get_paging(),
 "cat_paging_stats" => $getpaging->get_paging_stats()
));
$cache = array();
$i = 0;
foreach ($cache as $category_id){
if ($i >= $offset && $i <= $limit) {
$cache[] = $category_id;
   $cache_sql .= (($cache_sql != "") ? ", " : "").$category_id;
}
$i++;
}
$total = count($cache);</sup>


paging.php i've downloaded here http://gallery.vano.org/file18dl

so what could be wrong

[V@no]

what do u see in the url to the page 2,3,4? do u use page=2 or do u see cat_page=2 ?

[iraklis]

cat_page, i think i head also page, but i'm not shure. what's the wright one?

[iraklis]

ok it should be cat_page, like it is.

is it correct like that
domain/categories.php?cat_id=0&cat_page=2

cat_id is everytime 0 is this correct?

[V@no]

ok it should be cat_page, like it is.

is it correct like that
domain/categories.php?cat_id=0&cat_page=2

cat_id is everytime 0 is this correct?

no, its not correct...
are you sure u inserted the code from step 1.2 in the correct place?
I just realized that the string u were supposed to find in that step was misspelled, instead of

Code: [Select]

  $total = count($visible_cat_cache); it was supposed to be

Code: [Select]

  $total = sizeof($visible_cat_cache);(the original post updated)

[iraklis]

I changed what you wrote. But it doesn't work.

An other question, should this be like that?
  global $site_template, $site_db, $site_sess, $config, $lang, $HTTP_GET_VARS;
or like that
  global $site_template, $site_db, $site_sess, $config, $lang, $_GET;

[TheOracle]

4images is fully based on superglobals, so it's this one :

global $site_template, $site_db, $site_sess, $config, $lang, $HTTP_GET_VARS;

[iraklis]

that isn't the problem. but what i found out:

with

foreach ($visible_cat_cache as $key => $category_id) {

it works and i see the categories, limited by the script.

with

foreach ($cache as $category_id){

i can't see the categories

[TheOracle]

i can't see the categories

Correct. It has to stay with the $visible_cat_cache.

[iraklis]

Correct. It has to stay with the $visible_cat_cache.

so why is in the manual step 1.3 written,

Find:
Code:
foreach ($visible_cat_cache as $key => $category_id) {
Replace with:
Code:
foreach ($cache as $category_id){

there is my code like it is now, is anything wrong? i can't see any fault. may be you

Code: [Select]

$total = sizeof($visible_cat_cache);

//Begin configuration:

$perpage = 3; //how many categories per page
$cat_text = "Found {total_cat_images} categories on {total_pages} page(s). Displayed category {first_page} to {last_page}";

//u can use those tags:
//{total_cat_images} - total categories
//{total_pages} - total pages
//{first_page} - displayed from (number first category displayed)
//{last_page} - displayed to (number last category displayed)
//End configuration

$page = (isset($HTTP_GET_VARS['cat_page'])) ? $HTTP_GET_VARS['cat_page'] : 0;
if (!class_exists(Paging)) {
include(ROOT_PATH.'includes/paging.php');
}
$link_arg = $site_sess->url(ROOT_PATH."categories.php?".URL_CAT_ID."=".$cat_id);
$getpaging = new Paging($page, $perpage, $total, $link_arg, $cat_text, "", "cat_page");
$offset = $getpaging->get_offset();
$limit = ($offset + $perpage > $total) ? $total : $offset + $perpage - 1;
$total = $limit - $offset;
$site_template->register_vars(array(
 "cat_paging" => $getpaging->get_paging(),
 "cat_paging_stats" => $getpaging->get_paging_stats()
));
$cache = array();
$i = 0;
foreach ($visible_cat_cache as $key => $category_id) {
if ($i >= $offset && $i <= $limit) {
$cache[] = $category_id;
   $cache_sql .= (($cache_sql != "") ? ", " : "").$category_id;
}
$i++;
}
$total = count($cache);
//END MOD category for each page

[TheOracle]

Perhaps I missed something regarding this functionality but

replace :

foreach ($cache as $category_id){

with :

Code: [Select]


foreach ($visible_cat_cache as $category_id){



[iraklis]

like you can see in the code, it is already done.
