Get Children Ids Tag Parameters

tree_id=

tree_id="1"

The id of the tree you want to fetch. This is a required parameter.

entry_id=

entry_id="{entry_id}"

The entry_id of the node being requested. This is a required parameter.

Example Usage

The example below shows how we use the tag to pass the entry_ids of the current page's children into an embed to display teaser information for those child pages.

{exp:channel:entries limit="1" disable="categories|member_data|pagination"}

  <h2>{title}</h2>

  {main_content}

  {embed='includes/.teasers' entry_ids='{exp:taxonomy:get_children_ids tree_id="1" entry_id="{entry_id}"}'}

{/exp:channel:entries}

In the embedded template 'includes/.teasers' we would call the exp:channel:entries tag with the fixed_order parameter: fixed_order="{embed:entry_ids}" to keep the order in check with Taxonomy. It also uses Taxonomy's {exp:taxonomy:node_url} Tag to fetch each entries url.

{if "{embed:entry_ids}" != ""}
	<h3>In this section</h3>
	<ul>
	{exp:channel:entries fixed_order="{embed:entry_ids}" dynamic="no"}
		<li><a href="{exp:taxonomy:node_url entry_id='{entry_id}' tree_id='1'}">{title}</a></li>
	{/exp:channel:entries}
	</ul>
{/if}

At the time of writing, EE displays an sql error if a null fixed_order parameter is passed. I suggest you check the children do exist in the parent template before embedding the sub template until the good folks at Ellislab release the fixed version.
