WP query and multiple key - php

Question

I m trying to implement a multiple meta key filter in my wordpress. That's simple I get value to a form to filter my post. If I implement this with only "price" query wordked perfectly. If I add "genre" nothing work, query not working.
For field "genre" I m using checkbox from Advanced Custom Fields with this structure "homme : Homme / femme : Femme".
I test different thing like delete "price" and query on "genre" not working too...
I get value from this
<?php
if($_GET['minprice'] && !empty($_GET['minprice']))
{
$minprice = $_GET['minprice'];
} else {
$minprice = 0;
}
if($_GET['maxprice'] && !empty($_GET['maxprice']))
{
$maxprice = $_GET['maxprice'];
} else {
$maxprice = 1000;
}
if($_GET['genre'] && !empty($_GET['genre']))
{
$genre = $_GET['genre'];
}
?>
my query looks like this
$args = array(
'cat' => $cat,
'post_type' => 'post',
'posts_per_page' => 28,
'paged' => $paged,
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'prix',
'type' => 'NUMERIC',
'value' => array($minprice, $maxprice),
'compare' => 'BETWEEN'
),
array(
'key' => 'genre',
'value' => $genre,
'compare' => 'LIKE'
)
)
);
My loop with my query
<?php
// set up or arguments for our custom query
$paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
$args = array(
'cat' => $cat,
'post_type' => 'post',
'posts_per_page' => 28,
'paged' => $paged,
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'prix',
'type' => 'NUMERIC',
'value' => array($minprice, $maxprice),
'compare' => 'BETWEEN'
),
array(
'key' => 'genre',
'value' => $genre,
'compare' => 'LIKE'
)
)
);
// create a new instance of WP_Query
$the_query = new WP_Query($args);
?>
<?php if ( $the_query->have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post(); // run the loop ?>
<?php
get_template_part( 'content-category', get_post_format() );
?>
<?php endwhile; ?>
<?php if ($the_query->max_num_pages > 1) { // check if the max number of pages is greater than 1 ?>
<div class="clearfix"></div>
<?php bootstrap_pagination();?>
<?php } ?>
<?php else: ?>
<?php get_template_part( 'no-results', 'archive' ); ?>
<?php endif; ?>
</div>
<?php wp_reset_query(); ?>
I tested this and it's work !
$args = array(
'cat' => $cat,
'post_type' => 'post',
'posts_per_page' => 28,
'paged' => $paged,
'meta_query' => array(
array(
'key' => 'prix',
'type' => 'NUMERIC',
'value' => array($minprice, $maxprice),
'compare' => 'BETWEEN'
),
)
);
But that don't work
$args = array(
'cat' => $cat,
'post_type' => 'post',
'posts_per_page' => 28,
'paged' => $paged,
'meta_query' => array(
array(
'key' => 'genre',
'value' => $genre,
'compare' => 'LIKE'
)
)
);
Please, can you help me beacause I m loosing my mind....
Thanks !

I think you are missing an wrapping array in the meta_query
$args = array(
'cat' => $cat,
'post_type' => 'post',
'posts_per_page' => 28,
'paged' => $paged,
'meta_query' => array(
array(
'relation' => 'AND',
array(
'key' => 'prix',
'type' => 'NUMERIC',
'value' => array( $minprice, $maxprice ),
'compare' => 'BETWEEN'
),
array(
'key' => 'genre',
'value' => $genre,
'compare' => 'LIKE'
),
),
),
);
