Hello,
Thanks for this amazing plugin !
I m trying to implement a query on my wordpress. I want display post_type “enseignement” with two paramaters like “cycle1”, “cycle2″… and 2 meta_key “cycle”
and “lieu” like this code above.
<?php if($_GET['cycle'] && !empty($_GET['cycle']))
{
$cycle = $_GET['cycle'];
} else {
}
if($_GET['lieu'] && !empty($_GET['lieu']))
{
$lieu = $_GET['lieu'];
} else {
}
?>
<?php
$args = array(
'post_type' => 'enseignement',
'posts_per_page' => 10,
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'cycle', // name of custom field
'value' => $cycle, // matches exactly "red"
'compare' => 'LIKE',
),
array(
'key' => 'lieu',
'value' => $lieu,
'compare' => 'LIKE',
),
),
);
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post(); ?>
<?php get_template_part( 'content', 'enseignement', get_post_format() );?>
<?php endwhile; ?>
I have url like this this /?cycle=cycle1&lieu=paris and it’s work.
But if I want multiple “cycle” or multiple “lieu” like this /?cycle=cycle1,cycle2&lieu=paris,marseille I doesn’t work.
If I m trying to implement
$cycle = explode(',', $_GET['cycle']);
Like this
<?php
$cycle = explode(',', $_GET['cycle']);
$args = array(
'post_type' => 'enseignement',
'posts_per_page' => 10,
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'cycle', // name of custom field
'value' => $cycle, // matches exactly "red"
'compare' => 'IN',
),
array(
'key' => 'lieu',
'value' => $lieu,
'compare' => 'LIKE',
),
),
and this code doesn’t work too, nothing is show on my archives.
Please can you help me ?
Thanks
By the way I watched your video on vimeo but all my test was unsuccessfull.
What type of field are you searching? Are these ACF select fields or something else?
`
You need to use nested meta queries https://make.wordpress.org/core/2014/10/20/update-on-query-improvements-in-4-1/
and your going to need to dynamically generate the meta query. As an example the cycle portion of it might look something like this
$meta_query = array('relation' => 'AND');
if ($cycle) {
$sub_query = array('relation' => 'OR');
$cycles = explode(',', $cycle);
foreach ($cycles as $cycle) {
$sub_query[] = array(
'key' => 'cycle',
'value' => '"'.$cycle.'"'
'compare' => 'LIKE'
);
} // end foreach cycle
$meta_query[] = $sub_query;
} // end if cycle
Please note that the above has not been tested and is meant only as an example.
A word of caution, too many LIKE and nested LIKE queries could time out the request.
