How to search two meta values from same single column and table - php

Question

I make a custom search in WordPress. There are three fields for searching.
Age
Location
Post Title
Post Title is searched from wp_posts > post_title field and location and age are custom meta fields y_age, y_activity_locations. So there is 6 scenarios of searching.
If user enter:
Enter Title or
Select Location or
Select Age or
Enter Title and Select Location or
Enter Title and Select Age or
Select Location and Select Age
My first 5 (Five) scenarios are working perfectly but my 6th scenario is not working because it comes from same table (wp_postmeta) and same column but two different values.
So I tried this query:
Select y_posts.*, y_meta.*
From wp_posts As y_posts
Inner Join wp_postmeta As y_meta
On y_posts.ID = y_meta.post_id
Where y_posts.post_type = 'download'
And y_posts.post_status = 'publish'
And y_meta.meta_key = 'y_activity_locations'
And y_meta.meta_value Like '%Armidale%'
And y_meta.meta_key = 'y_age'
And y_meta.meta_value Like '%3 to 5%'
The query is not working because I think sever confused two values from same column.
Select y_posts.*, y_meta.*
From wp_posts As y_posts
Inner Join wp_postmeta As y_meta
On y_posts.ID = y_meta.post_id
Where y_posts.post_type = 'download'
And y_posts.post_status = 'publish'
And y_meta.meta_key = 'y_activity_locations'
And y_meta.meta_value Like '%Armidale%'
Or y_meta.meta_key = 'y_age'
Or y_meta.meta_value Like '%3 to 5%'
This query works and it gives me only age or location data but i want search both values at a same time.
I also tried sub query (Never tried before)
Select y_posts.*, y_meta.*
From wp_posts As y_posts
Inner Join wp_postmeta As y_meta
On y_posts.ID = y_meta.post_id
Where y_posts.post_type = 'download'
And y_posts.post_status = 'publish'
And y_meta.meta_key = 'y_activity_locations'
And y_meta.meta_value Like '%Armidale%'
And (Select yy_meta.* From wp_postmeta As yy_meta Where yy_meta.meta_key = 'y_age'
And yy_meta.meta_value Like '%3 to 5%')
But it gives me this error
1241 - Operand should contain 1 column(s)
So please guide me how can I get two values from same column.
Please give me only query suggestions not any other solutions.

Answer 1

Please try following query :
Select y_posts.*, y_meta.*
From wp_posts As y_posts
Inner Join wp_postmeta As y_meta
On y_posts.ID = y_meta.post_id
Where y_posts.post_type = 'download'
And y_posts.post_status = 'publish'
And (
(y_meta.meta_key = 'y_activity_locations'
And y_meta.meta_value Like '%Armidale%')
Or (y_meta.meta_key = 'y_age'
And y_meta.meta_value Like '%3 to 5%')
)

You try, wordpress query
<?php
$argsCat = array(
'posts_per_page' => -1,
'post_type' => 'download',
'meta_key' => 'y_activity_locations',
'meta_value' => '%Armidale%',
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'y_age',
'value' => '3',
'compare' => '>='
),
'relation' => 'AND',
array(
'key' => 'y_age',
'value' => '5',
'compare' => '<='
)
),
);
$normal_array = get_posts($argsCat);
?>
