Plugin: Child Categories

Hi,

Your code should be:

{if "{child_category_id}"=="50" OR "{child_category_id}"=="51" OR "{child_category_id}"=="52" OR "{child_category_id}"=="53"} 
Some code
{/if}

I’ve got two parent category groups, and I’m trying to re-create this bit of code to show the one (or more) categories that have been selected for an entry:

{categories backspace="1" show="not 17|18|19|20|21|22|77|78|79|80|81|82|83|84|85"}{category_name}, {/categories}

with the child categories plugin:

{exp:child_categories parent="17"}
{child_category_start}{child_category_name}, {child_category_end}
{/exp:child_categories}

But instead of just getting one category out, I get all the child categories shown. Have I got the wrong end of the stick somewhere?

Thanks,

Hi Luc,

Your code should be as this:

{exp:child_categories parent="17"}
{child_category_start}

{if "{child_category_id}" != "17" AND "{child_category_id}" != "18" AND "{child_category_id}" != "19"}
{child_category_name},
{/if} 

{child_category_end}
{/exp:child_categories}

A quick suggestion (unless there’s another way round it):

{child_category_children_count}

I want to list out all child categories from a given parent, but I want to make the child categories a link only if they have child categories themselves…

• Parent 1 —Child 1 (not a link because {child_category_children_count} == 0) —Child 2 (link because {child_category_children_count} == 2) ——Child 2’s Child 1 ——Child 2’s Child 2 —Child 3 (not a link because {child_category_children_count} == 0)

Hi Steve,

Child categories plugin is meant only to output categories 1 level deep, i.e. parent categories and their children, not childrens’ children.

If you want to display categories more than 1 level deep you might find the plugin Recursive Subcategories useful.

Hi - thanks for a quick response.

Understood re: displaying more than one level, however I’m actually only wanting to display parent and child, the problem is I want to make the child clickable ONLY if it has children itself (I don’t want to actually display the child’s children).

I’ll try the recursive subcategories plugin, but I found your one perfect (since I can display entries too with the same code).

Thanks! Steve.

If you don’t want to display childrens’ Children, then it it possible to achieve what you need:

{if "{child_category_children_count}"=="0"}
Code without link
{/if}
{if "{child_category_children_count}">"0"}
Code with link
{/if}

Oh - does {child_category_children_count} exist? Oops, that’s what I was suggesting, I didn’t see it in the documentation.

Opps! - I assumed you are talking about existing variable…

Sorry - no, I was making a suggestion/feature request. :D

You can use Child categories plugin together with Category Info plugin.

Hi Luc, Your code should be as this:

{exp:child_categories parent="17"}
{child_category_start}

{if "{child_category_id}" != "17" AND "{child_category_id}" != "18" AND "{child_category_id}" != "19"}
{child_category_name},
{/if} 

{child_category_end}
{/exp:child_categories}

Hi, That just outputted the same as I had - every child category, regardless of it being selected. I should have probably said that category_id 17 and 18 are the parents, all the rest are children.

Hi Luc,

That just outputted the same as I had - every child category, regardless of it being selected. I should have probably said that category_id 17 and 18 are the parents, all the rest are children.

I don’t understand which one category you want to output. How do you distinguish selected category from others? And what do you mean by “selected category”?

What I mean, and what I get from my code (although I have to manually enter category IDs when they’re added to, hence the use of this plugin), is a list of child categories that have been selected for that particular entry. For example, I have categories set up like

17 - Parent 1 —- Child 1 —- Child 2 —- Child 3

18 - Parent 2 —- Child 4 —- Child 5 —- Child 6

Selecting “Child 2” in the publish/edit screen should then only output “Child 2” in my template.

Hope that’s clearer…
