wordpress custom mysql query - mysql

Question

In wordpress How can we fetch records in specific order within meta field value for eg I need to fetch all records where zip_code(meta key name) is all fields with 60007 first than all 60143 than 60191
Table drrr_posts
Id | post_name | content
2
3
4
22
32
43
Table drrr_postmeta
id | meta_key | meta_value | post_id
1 | zip_code | 60143 | 2
2 | zip_code | 60007 | 3
3 | zip_code | 60191 | 4
4 | zip_code | 60143 | 22
5 | zip_code | 60007 | 32
6 | zip_code | 60143 | 43
I think issue is I am passing ORDER BY FIELD( drrr_postmeta.meta_value not zip_code which is meta_key
In mysql I can easily pass the values in ORDERBY like
ORDER BY FIELD(name, 'B', 'A', 'D', 'E', 'C')
here is what I have now
My Query is
SELECT SQL_CALC_FOUND_ROWS drrr_posts.ID
FROM drrr_posts
INNER JOIN drrr_term_relationships ON ( drrr_posts.ID = drrr_term_relationships.object_id )
INNER JOIN drrr_postmeta ON ( drrr_posts.ID = drrr_postmeta.post_id )
INNER JOIN drrr_postmeta AS mt1 ON ( drrr_posts.ID = mt1.post_id )
WHERE 1 =1
AND drrr_posts.ID NOT
IN ( 91, 89, 87, 66 )
AND (
drrr_term_relationships.term_taxonomy_id
IN ( 11 )
)
AND drrr_posts.post_type = 'doctors'
AND (
(
drrr_posts.post_status = 'publish'
)
)
AND (
drrr_postmeta.meta_key = 'zip_code'
AND (
mt1.meta_key = 'zip_code'
AND CAST( mt1.meta_value AS SIGNED )
IN (
'60007', '60143', '60191', '60005', '60106', '60157', '60173', '60008', '60056', '60172'
)
)
)
GROUP BY drrr_posts.ID
ORDER BY FIELD( drrr_postmeta.meta_value, '60007', '60143', '60191', '60005', '60106', '60157', '60173', '60008', '60056', '60172' )
LIMIT 0 , 8

Answer 1

You can order your results by meta_key by adding one more conditional order by ,also your group by statement doesn't make any sense in absence of aggregate function ,for now you can do this
ORDER BY
drrr_postmeta.meta_key ='zip_code' desc,
FIELD( drrr_postmeta.meta_value, '60007', '60143', '60191', '60005', '60106', '60157', '60173', '60008', '60056', '60172' )
Using drrr_postmeta.meta_key ='zip_code' will result as a boolean and returns true if both matches so it will order results first by zip_code matching meta_key and then you field() function will order results accordingly
