I got some post in some categories { kids, man, woman } , and some ACF meta fields per country { Japan, South Korea ... }.

If I query the categories with this tax_query it works perfectly:

Array
(
    [tax_query] => Array
        (
            [0] => Array
                (
                    [taxonomy] => category
                    [field] => slug
                    [terms] => Array
                        (
                            [0] => kids
                        )    
                )    
        )    
)

This returns all the posts in kids category.

But weirdly, once I select also country ( japan for example ) and this adds the meta_query, it seems to overwrite the tax_query and I just get the results for country ignoring the category filter for kids ...

Array
(
    [meta_query] => Array
        (
            [relation] => OR
            [0] => Array
                (
                    [0] => Array
                        (
                            [key] => country
                            [value] => Japan
                            [compare] => LIKE
                        )    
                )    
        )    
    [tax_query] => Array
        (
            [taxonomy] => category
            [field] => slug
            [terms] => Array
                (
                    [0] => kids
                )    
        )    
)

This returns all the post for japan.

The code that generates that query is this one:

// ADDS TAX QUERY PER TYPE
$brands_query = array(
  'taxonomy'     => 'category',
  'field'        => 'slug',
  'terms'        => $post_brands['brandList']
);

// ADDS A META QUERY PER COUNTRY
$countries_query = array('relation' => 'OR');
foreach ($post_countries['countryList'] as $value) {
  $countries_query[][] = array(
    'key'       => 'country',
    'value'     => $value,
    'compare'   => 'LIKE',
  );
}

$args = array(
  'meta_query'     => $countries_query,
  'tax_query'      => $brands_query,
);
  • There's another question here which may shed some link on things - although it does suggest you should get the result of meta_query AND tax_query. It may be worth looking at the SQL generated with e.g. Query Monitor if you can. stackoverflow.com/questions/24743202/… – mozboz Jul 10 at 11:51
  • This is the query generated dynamically by the the code, the code "seems to work" because this is what I meant to output for the query, what it doesn't work is the query itself. For what I see on the other question on your comment, they are trying to generate an OR between the tax_query and the meta_query, and that's whats not possible with wordpress, in my case I just need an AND query that should work fine, but it doesn't. – Fabman Jul 10 at 11:59
  • What do you think about looking the SQL that's generated by your query? – mozboz Jul 10 at 12:30
  • I'm checking that right now, but I was avoiding it because supposedly this was easily supported natively by wordpress. But I think I'm not going to have other choice but to make the query with sql myself. – Fabman Jul 10 at 12:32
  • The other question I linked to suggests that the SQL that gets built is exactly what you want, so maybe there's something else going on. – mozboz Jul 10 at 12:34

Tax query is formed wrong. It also array of arrays(queries)

get_posts([
    'meta_query'    => [
        [
        'key' => 'country',
        'value' => 'Japan',
        'compare' => 'LIKE' 
        ]   
    ],
    'tax_query' => [
        [
            'taxonomy'  => 'category',
            'field'     => 'slug',
            'terms'     => ['kids']
        ]
            
    ]
]);

the array should look like this:

Array
(
    [meta_query] => Array
        (
            [relation] => OR
            [0] => Array
                (
                    [0] => Array
                        (
                            [key] => country
                            [value] => Japan
                            [compare] => LIKE
                        )
                )
        )

    [tax_query] => Array
        (
            [0] => Array
                (
                    [taxonomy] => category
                    [field] => slug
                    [terms] => Array
                        (
                            [0] => kids
                        )
                )
        )
)

  • The tax_query is already an array, and the terms inside is also an array like your example. – Fabman Jul 10 at 12:25

    I though the same but OP is showing what the args look like from e.g. print_r – mozboz Jul 10 at 12:29

    @mozboz I check his dump again - second part, where he displays meta & tax query in one array is wrong in tax part – Az Rieil Jul 10 at 13:59

    @Fabman check my answer and you upd. code again - you missing inside array for taxonomy query. tax query, as meta query, must be array of array of queries. even if it only one query. Or just wrap $brands_query into additional array – Az Rieil Jul 10 at 14:01

    Your answer was perfect, I just edited it so the structure looks the same way the question was presented ( with a print_r of the query ). Thank you very much for your help! – Fabman Jul 10 at 14:11
