[MOD] limited number of categories per page (updated 08-06-2006)

[iraklis]

could someone send me his "funktion.php" ??? 

[TheOracle]

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

That is the original coding.

The instructions says :

foreach ($cache as $category_id) {

And now, replace it with :

Code: [Select]


foreach ($visible_cat_cache as $category_id) {

Please! u dont know what u are talking about, period!

@iraklis:
please show the block of code started from line:

Code: [Select]

function get_categories($cat_id = 0) {and ended with:

Code: [Select]

function get_category_path($cat_id = 0, $detail_path = 0) {

FYI

i also add this mod

http://www.4homepages.de/forum/index.php?topic=6675

but this souldn't disturb this one !?

[TheOracle]

i also add this mod

Ah ! this wasn't mentionned first.

but this souldn't disturb this one !?

If that MOD is related with the same functions as this one, it might become a problem due to a slight difference of codes.

[iraklis]

in this mod you've just to configure the template category_bit.html. so don't think that this is the problem. i thought you know that with both mods combiend, there are problems. so it's not that

[TheOracle]

in this mod you've just to configure the template category_bit.html. so don't think that this is the problem. i thought you know that with both mods combiend, there are problems. so it's not that

I meant no disrespect. I was just making sure they had no conflicts.

no, it will not affect.

I just tested your code on a fresh 4images, the paging worked just fine, but no subcategories where showed because of

Code: [Select]

   if ($categories && function_exists('get_subcategories') && $num_images >= 1) {condition. (I dont know where this came from)


What happens if you insert above:

Code: [Select]

$total = sizeof($visible_cat_cache);this:

Code: [Select]

echo $cat_id."<br />";The idea it should show u the category id on top of the page.

[iraklis]

it's 0

like the url: domain/categories.php?cat_id=0&cat_page=4

[V@no]

just to confirm, if you uinstall this mod, do u still get 0? (I have a feeling that 0 is what u'll get without this mod)

If so, then there is something wrong in your categories.php, perhaps other mods affecting

[iraklis]

i upload the original categories.php, so that can't be the problem.

if i would write the url ^{domain/categories.php?cat_id=3&cat_page=4} by my self. should it work? i tried it but it doesn't.

i also upload the original function.php and the cat_id is also 0

[iraklis]

if i write this url in the browser domain/categories.php?cat_id=13&cat_page=2 i get the page with the pictures of categorie 13 and not the cat_page2. i don't know if it's normal!?

[iraklis]

FYI

Step 3.
Add in /templates/<yourtemplate>/categories.html
those tags:
{cat_paging} and if u want {cat_paging_stats}

i didn't change the template categories.html, i changed the home.html. i don't know if this could be the problem!?

second thing
i took the original function.php modify it like it's written in the manual, but i've the same problem.

[TheOracle]

i didn't change the template categories.html, i changed the home.html. i don't know if this could be the problem!?

In these circumstances, it must be done from categories.html and not home.html since no paging defaultly exists from home.html file.
