Wordpress Query + ACF Meta Query - php

Question

I am looking for a code that can contain all queries in one.
The part of the code is :
<?php $query = new WP_Query(array ( 'post_type' => 'post', 'posts_per_page' => '6', 'order' => 'DESC', 'tax_query' => array(
array(
'taxonomy' => 'type-article',
'field' => 'slug',
'terms' => array( 'interview', 'tribune' )
) ) ));
while ( $query->have_posts() ) :
$query->the_post(); ?>
<?php if($post->post_type == "post"){ $version_FR = get_field('versionFRexiste'); $langue = get_field('langue'); }; ?>
<?php if($langue == "FR" || ($langue == "EN" && $version_FR == "Non")) : ?>
[some code]
<?php endif; ?>
<?php endwhile; ?>
inside the WHILE, you find two lines with IF
I would like to include these condition in the query at the TOP where WP_Query.
This code is working but my problem is that I would like to have the same number of results to display (6 here)
Thanks for your help

Answer 1

Please have a look here on the ACF Docs.
The answer is to write a meta query within the WP-Query, such as:
$posts = get_posts(array(
'numberposts' => -1,
'post_type' => 'post',
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'color',
'value' => array('red', 'orange'),
'compare' => 'IN',
),
array(
'key' => 'featured',
'value' => '1',
'compare' => '=',
),
),
));

Thanks. It was not so easy... but the metaquery won
<?php $query = new WP_Query(array ( 'post_type' => 'post', 'posts_per_page' => '5', 'order' => 'DESC',
'meta_query' => array(
'relation' => 'OR',
array(
'key' => 'langue',
'value' => 'FR'
),
array(
'relation' => 'AND',
array(
'key' => 'langue',
'value' => 'EN'
),
array(
'key' => 'versionFRexiste',
'value' => 'Non'
)
)
),
'tax_query' => array(
array(
'taxonomy' => 'type-article',
'field' => 'slug',
'terms' => array( 'interview', 'tribune' )
) ) ));
Hope this will help those who need an answer
