Hi there,
I’ve followed the tutorial here: http://www.advancedcustomfields.com/resources/tutorials/querying-the-database-for-repeater-sub-field-values/
To retrieve posts by a specific sub-field value.
However, i need what i’d call a “double match” 🙂 I have to get posts according to 2 subfield values. How can i combine these queries in one?
Another thing that would be nice to add in that query, is to check the post_status key in the wp_posts table.
Unlickily i don’t have any MySQL knowledge and my attempt to solve the problem failed!
Can you help me? 🙂
I was able to manage it somehow. This is the sql query. It retrieve all the published posts of post_type “attivita”, according to the language (i’m using polylang) and to the “dayname” key_value.
$language = pll_current_language();
$rows = $wpdb->get_results($wpdb->prepare(
"
SELECT *
FROM wp_posts
INNER JOIN wp_postmeta m1
ON (wp_posts.ID = m1.post_id)
INNER JOIN wp_term_relationships wtr
ON (wp_posts.ID = wtr.object_id)
INNER JOIN wp_term_taxonomy wtt
ON (wtr.term_taxonomy_id = wtt.term_taxonomy_id)
INNER JOIN wp_terms wt
ON (wt.term_id = wtt.term_id)
WHERE
wp_posts.post_type = 'attivita'
AND wp_posts.post_status = 'publish'
AND wtt.taxonomy = 'language'
AND wt.slug = %s
AND (m1.meta_key LIKE %s AND meta_value = %s)
",
$language,
'orario_%_giorno', // meta_name: $ParentName_$RowNumber_$ChildName
$dayname // meta_value: 'type_3' for example
));
Now i’m trying to display posts according to the starting time, stored as a subfield (attivita means activity, it’s a sort of calendar). all the activities take place in the morning (starting 9am) or in the afternoon (starting 3pm).
So the code above is inserted in a while loop that counts day-by-day at each loop, and inside the while loop i have two foreach that displays the activities within each single day, for the morning and the afternoon respectively.
