Count Correct Terms for Display Pagination WordPress

  • SOLVED

Hi, all. I have the code below in a page template for a child term. The code displays a list (in grid view) of the terms associated to it's parent (ID 16). The parent's name is Basic Materials and it's slug is "basic-materials".

<strong>The problem</strong> I have is that the pagination is counting the number of terms in the taxonomy instead of the specific parent term. So in this case what should only show two page links is showing over 18 because that is how many pages get shown when viewing ALL terms. Can someone help me figure out how to make it count the # of terms in the parent and have the right number of page links display?

hi,
...something is not logical


$number_of_terms = wp_count_terms( '100list' ); // hide_empty = true

$libargs = array(
....
'hide_empty' => 0,
....
);


change to


$number_of_terms = wp_count_terms( '100list', array('hide_empty' => false) );

Excellent! Martin Pham, this is working beautifully! Thank you!!!

Martin Pham comments:

Because

$number_of_terms = wp_count_terms( '100list' );


===> return an incorrect result, it includes the results are not a child of 16.

you can see more in codex:

http://codex.wordpress.org/Function_Reference/wp_count_terms

John Cotton answers:

Surely this:

$number_of_terms = wp_count_terms( '100list' );

should be this:

$number_of_terms = wp_count_terms( '100list', array( 'parent' => $parent_id ) );

where $parent_id is the id of basic-materials.

streetfire comments:

John, that actually worked quite well too! :D

I wonder which "working" method is best, lol

John Cotton comments:

<blockquote>I wonder which "working" method is best, lol</blockquote>
I think they are essentially the same.

Your problem was that you were filtering your term count, hence getting the count for all terms.

You need to look at the args param for get_terms (it's the same as wp_count_terms).

streetfire comments:

John, Thank you. In all honesty I was studying that link before I posted, but I need to understand better how everything all works together I believe. I'm still learning php functions the core wordpress functionality...

Fahad Murtaza answers:

If I understood the question correctly, something along these lines should work


$parent = get_queried_object()->parent; // Get parent of the current term



The above should give you the parent which you can use within

wp_count_terms as parameter.

Let me know if that helps.

streetfire comments:

Hm, like this?

$number_of_terms = wp_count_terms( '100list', array ($parent = get_queried_object()->parent) );

That doesn't work. If I didn't insert it right please provide more information. Thanks

Fahad Murtaza comments:

$parent = get_queried_object()->parent; // Get parent of the current term
$number_of_terms = wp_count_terms( '100list', array( 'parent' => $parent ) ); // You can make it more dynamic by inserting the dynamic variable for '100list'

Fahad Murtaza comments:

I see, you got it solved already!

streetfire comments:

Hi, yes I think we do! Seems a couple of ways to do it :) You ALL were most helpful. I will be visiting here more often ;)

change this part:

$per_page = 12;
$number_of_terms = wp_count_terms( '100list' ); // This counts the total number terms in the taxonomy with a function)
$paged_offset = ($paged - 1) * $per_page;
$libargs = array(

'number' => $per_page,
'offset' => $paged_offset,
'parent' => '16',
);
$libcats = get_terms( '100list', $libargs);
$i = 0;

with:

$per_page = 12;
//removed
$paged_offset = ($paged - 1) * $per_page;

$libargs = array(
'orderby' => 'name',
'order' => 'ASC',
'hide_empty' => 0,
'exclude' => array(), //* Enter ID's of parent categories to exclude from list
'number' => $per_page,
'offset' => $paged_offset,
'parent' => '16',

$libcats = get_terms( '100list', $libargs);
$number_of_terms = wp_count_terms( '100list', $libargs); //addition
$i = 0;
