Tax_query not working in wordpress. how to solve? - php

Question

I made a page template where i can filter some posts. If u do a normal WP_Query everything is fine. But if i use the tax_query it displays no posts.
for registering the post types and taxonomies i use the plugin 'cptui'.
The regular WP_Query request:
$query = new WP_Query(array(
'post_type' => $post->post_name,
'post_status' => 'publish',
'posts_per_page' => 6,
'paged' => $paged,
));
if(!$_POST) { //If not filtered ... then show all
if($query->have_posts()): while ($query->have_posts()) : $query->the_post();
echo "<a href='".get_post_permalink()."'><div style='box-shadow: 0 0 15px 0 rgba(0,0,0,.05); padding: 50px; width: 100%; margin: 5px; '>";
echo "<h5>" . $query->post->post_title . "</h5>";
echo "<p>" . get_field( "plaats" ) . '-' . get_term(get_field('dienstverbanden'))->name . "</p>";
echo "</div></a>";
endwhile; endif;
}
I read other posts and they said i could use the php echo $GLOBALS['query']->request; to see what the mysql query is.
My query is:
SELECT SQL_CALC_FOUND_ROWS wp_posts.ID
FROM wp_posts
WHERE 1 = 1
AND wp_posts.post_type = 'vacature'
AND ((wp_posts.post_status = 'publish'))
ORDER BY wp_posts.post_date DESC
LIMIT 6, 6
and now the request with the tax_query.
The tax_query WP_Query request:
$query = new WP_Query(array(
'post_type' => $post->post_name,
'post_status' => 'publish',
'posts_per_page' => 6,
'paged' => $paged,
'tax_query' => array(
array(
'taxonomy' => 'provincie',
'field' => 'slug',
'terms' => 'noord-brabant',
'include_children' => 0
),
),
));
if(!$_POST) { //If not filtered ... then show all
if($query->have_posts()): while ($query->have_posts()) : $query->the_post();
echo "<a href='".get_post_permalink()."'><div style='box-shadow: 0 0 15px 0 rgba(0,0,0,.05); padding: 50px; width: 100%; margin: 5px; '>";
echo "<h5>" . $query->post->post_title . "</h5>";
echo "<p>" . get_field( "plaats" ) . '-' . get_term(get_field('dienstverbanden'))->name . "</p>";
echo "</div></a>";
endwhile; endif;
}
The query I get now is:
SELECT SQL_CALC_FOUND_ROWS wp_posts.ID
FROM wp_posts
LEFT JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id)
WHERE 1 = 1
AND (wp_term_relationships.term_taxonomy_id IN (3))
AND wp_posts.post_type = 'vacature'
AND ((wp_posts.post_status = 'publish'))
GROUP BY wp_posts.ID
ORDER BY wp_posts.post_date DESC
LIMIT 6, 6
and I get no posts back.
Do you know any solution for this?
Full code of the template:
<div id="page-<?php the_ID(); ?>" <?php post_class(); ?>>
<?php the_content(); ?>
<?php
global $post;
$paged = ( get_query_var('paged')) ? get_query_var('paged') : 1;
$query = new WP_Query(array(
'post_type' => $post->post_name,
'post_status' => 'publish',
'posts_per_page' => 6,
'paged' => $paged,
'tax_query' => array(
array(
'taxonomy' => 'provincie',
'field' => 'slug',
'terms' => array( 'noord-brabant')
)
)
));
// echo $GLOBALS['query']->request;
if(!$_POST) { //If not filtered ... then show all
if($query->have_posts()): while ($query->have_posts()) : $query->the_post();
echo "<a href='".get_post_permalink()."'><div style='box-shadow: 0 0 15px 0 rgba(0,0,0,.05); padding: 50px; width: 100%; margin: 5px; '>";
echo "<h5>" . $query->post->post_title . "</h5>";
echo "<p>" . get_field( "plaats" ) . '-' . get_term(get_field('dienstverbanden'))->name . "</p>";
echo "</div></a>";
endwhile; endif;
}
else { //now its filtered
$null = true;
if($query->have_posts()): while ($query->have_posts()) : $query->the_post();
$filterconditions = []; //hier komen alle filtercondities in
$keys = array_keys($_POST);
foreach($keys as $key) {
if($_POST[$key] == "on") {
$filter = explode("_",$key);
$field = $filter[0];
$filter = $filter[1];
$taxonomy = get_field( $field );
$term = get_term_by('term_id', $taxonomy, $field);
array_push($filterconditions, '"' . $filter . '"' . '==' . '"' . $term->name . '"');
}
};
$filterconditions = implode('&&', $filterconditions);
// echo $filterconditions;
if(eval("return $filterconditions;")) {
$null = false;
echo "<a href='".get_post_permalink()."'><div style='box-shadow: 0 0 15px 0 rgba(0,0,0,.05); padding: 50px; width: 100%; margin: 5px; '>";
echo "<h5>" . $query->post->post_title . "</h5>";
echo "<p>" . get_field( "plaats" ) . '-' . get_term(get_field('dienstverbanden'))->name . "</p>";
echo "</div></a>";
}
endwhile; endif;
if($null) {
echo "Sorry, er zijn geen vacatures gevonden met deze filters";
}
}
$total_pages = $query->max_num_pages;
if ($total_pages > 1 && !$null) {
$current_page = max(1, get_query_var('paged'));
echo paginate_links(array(
'base' => get_pagenum_link(1) . '%_%',
'format' => '/page/%#%',
'current' => $current_page,
'total' => $total_pages,
'prev_text' => __('« prev'),
'next_text' => __('next »'),
));
}
wp_reset_query();
?>
</div>

Answer 1

$args=array(
'post_type' => 'your_post_type',
'post_status' => 'publish',
'orderby' => 'title',
'order' => 'DESC',
'posts_per_page' => 6,
'tax_query' => array(
array(
'taxonomy' => 'provincie',
'field' => 'slug',
'terms' => array( 'noord-brabant')
)
)
);
$result = new WP_Query( $args );
// The Loop
if ( $result->have_posts() ) {
while ( $result->have_posts() ) {
$result->the_post();
// this is your loop
}
} else {
// nothing
}
Can try above code

Answer 2

You can get simple custom post type list using below code:
$args = array(
'post_type' => 'services',
'post_status' => 'publish',
'posts_per_page' => 6,
'orderby’ => 'title',
'order’ => 'ASC',
);
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
print the_title();
the_excerpt();
endwhile;
wp_reset_postdata();
Place your custom post type name to retrieve post and change the while loop according to your need

Answer 3

Ok can you use get post method instead of WP Query:
$posts_array = get_posts(
array(
'posts_per_page' => 6,
'post_type' => $post->post_name, // Get POST TYPE FROM $GLOBAL POST
'tax_query' => array(
array(
'taxonomy' => 'provincie',
'field' => 'slug',
'terms' => 'noord-brabant',
)
)
)
);
