Hello,
I’ve been trying to achieve something and I can’t figure out how to do…
First of all let me explain what I have :
– I have a custom post type call student, with a post_title (the student full name) and an objet called “parent”, of type user
– I have my users who have custom fields like firstname, lastname, address, etc.
What I need to do is : search for all the students whose name contains a given string OR their parent’s name.
I tried to use get_posts to achive that but I didn’t succeed.
So I tried with wpdb, thinking I could write the sql query more easily but that’s not the case…
For now I have :
query 1:
SELECT * FROM wp_posts WHERE
post_status LIKE ‘publish’
AND post_type LIKE ‘student’
AND post_title LIKE ‘%$searched_string’
It’s working fine, it was not the hardest part 🙂
On the other hand I tried to get all the users whose first of lastname contains the string, so I have this query :
query 2:
SELECT * FROM wp_users u
INNER JOIN wp_usermeta um
ON um.user_id = u.ID
WHERE um.meta_key = ‘first_name’
AND um.meta_value LIKE ‘%searched_string%’
OR um.meta_key = ‘last_name’
AND um.meta_value LIKE ‘%searched_string%’
This gives me the list of parents, no problem neither.
Now I need to get the students related to these parents, and I don’t know how to do because parents id are stored into post_meta table, like this :
a:2:{i:0;s:1:”4″;i:1;s:1:”6″;}
Here the students has 2 related parents, of IDs 4 and 6.
I have no way to do something like :
SELECT * FROM wp_posts WHERE
post_status LIKE ‘publish’
AND post_type LIKE ‘student’
AND post_title LIKE ‘%$searched_string’
OR parent_id IN (4, 3)
In this example I could get parents IDs with query 2, and then construct query 1 to say that student’s parents ID have to be one of the IDs found.
I don’t know if I’m clear but what I know is I’m stuck.
Any idea of how I could achive that ?
Thanks a lot.
