Hi,

I have created a custom field with Field Type as Taxonomy and Taxonomy selected as Categories.

I want to echo the Category selected by the user in the Page which I can use it in my code.

Below is the code in which I want to use the select Category:

<?php $args = array(
	'posts_per_page'   => 3,
	'offset'           => 0,
	'category'         => '$value',
	'orderby'          => 'post_date',
	'order'            => 'DESC',
	'include'          => '',
	'exclude'          => '',
	'meta_key'         => '',
	'meta_value'       => '',
	'post_type'        => 'post',
	'post_mime_type'   => '',
	'post_parent'      => '',
	'post_status'      => 'publish',
	'suppress_filters' => true ); ?>

For the variable $value, I want the category to be selected. I am new to custom development and need your help in using this plugin.

I checked out the post http://www.advancedcustomfields.com/resources/how-to/how-to-get-values-from-a-taxonomy-term/ but was not able to implement the same.

I tried something like this $value = get_field_objects('select_category_for_news', 'category_1'); ?>

Thank you,

Hi @cshirish

To load the selected values from a taxonomy field, you can use the get_field function like so:

$selected = get_field('taxonomy_field_name');

I just looked at the get_posts documentation and the following is very useful:

Note: The category parameter needs to be the ID of the category, and not the category name.

Note: The category parameter can be a comma separated list of categories, as the get_posts() function passes the 'category' parameter directly into WP_Query as 'cat'. 

So, with that in mind, please edit your taxonomy field and select ‘ID’ as the return format setting. Then you can use the following code:

$selected = get_field('taxonomy_field_name');

$args = array(
	'posts_per_page'   => 3,
	'offset'           => 0,
	'category'         => implode(',',$selected),
	'orderby'          => 'post_date',
	'order'            => 'DESC',
	'include'          => '',
	'exclude'          => '',
	'meta_key'         => '',
	'meta_value'       => '',
	'post_type'        => 'post',
	'post_mime_type'   => '',
	'post_parent'      => '',
	'post_status'      => 'publish',
	'suppress_filters' => true );

Hope that helps.

Thanks
