#StackBounty: #php #wordpress #twig #advanced-custom-fields #timber Timber Twig: query a Custom Post Type by category and output a shor…

Bounty: 50

What I’m trying to do is generate a new Custom Post Type called report, add a taxonomy, query the reports, and then generate a shortcode in the format of [report_listing category="general"] to display the reports in the category General.

Right now, on report/index.twig, I get a listing of all reports using the shortcode [report_listing], and the error No reports available when using [report_listing category="general"].

I am using Advanced Custom Fields, but that doesn’t appear to be an issue with this or the rest of the site. The categories are being generated and associated with the posts, since this is a sample {{ dump }} output on /index.twig for one report when using [report_listing] and all reports are displayed:

["report_category"]=> array(1) { [0]=> object(TimberTerm)#2131 (15)
{ ["PostClass"]=> string(11) "TimberPost" ["TermClass"]=> string(4) "Term"
["object_type"]=> string(4) "term" ["_children"]=> NULL ["name"]=> string(7)
"General" ["taxonomy"]=> string(15) "report_category" ["id"]=> int(89) ["ID"]=> int(89)
["term_id"]=> int(89) ["slug"]=> string(7) "general" ["term_group"]=> int(0)
["term_taxonomy_id"]=> int(89) ["parent"]=> int(0) ["count"]=> int(0) ["filter"]=> string(3) "raw" } } 

I looked at ACF Querying custom post types with taxonomies , but I am using tax_query parameters. There are no php errors on the debug log.

Full code in the plugin that generates the custom post type and generates the shortcode:
