I know we can filter posts with a featured image by using
'meta_query' => array(
array( 'key' => '_thumbnail_id'),
)
in WP_Query()
But how do I get posts without featured image?
Try this?
$args = array(
'meta_query' => array(
array(
'key' => '_thumbnail_id',
'value' => '?',
'compare' => 'NOT EXISTS'
)
),
);
$new_query = new WP_Query( $args );

I am trying to exclude posts from query and it is not working at all.
Here what I tried
<?php
$args = array(
'post_type' => 'videos-presentations',
'post_status' => 'publish',
'posts_per_page' => 4,
'paged' => $paged,
'meta_query' => array(
array(
'meta_key' => '_is_ns_featured_post',
'meta_value' => 'yes',
'meta_compare' => '!='
)
)
);
$my_query = new WP_Query($args);
?>
Also Tried with
'meta_compare' => 'NOT EXIST'
and
'meta_compare' => 'NOT IN'
Any idea what I am doing wrong?
Got it. From here
It Works with just
'meta_query' => array(
array(
'key' => '_is_ns_featured_post',
'compare' => 'NOT EXISTS'
)
)
function exclude_posts ( $query ) {
$meta_query = $query->get( 'meta_query' );
$meta_query[] = array(
'key'=>'_is_ns_featured_post',
'value'=>'yes',
'compare'=>'!=',
);
$query->set( 'meta_query',$meta_query );
}
add_action( 'pre_get_posts', 'exclude_posts' );
place this code in functions.php file of active theme
Trying to pull post type according to their excerpt value.
my code so far:
$ids = array(111,333,9061);
$args = array (
'post_type' => 'kb',
'posts_per_page' => -1,
'meta_query' => array (
array(
'key' => 'excerpt',
'value' => $ids,
'compare' => 'IN'
)
)
);
$the_query = new WP_Query( $args );
If I remove the meta_query it pulls the posts.
Also tried with 'key' => 'post_excerpt'
Any ideas?
I would like to retrieve all those posts whose author (post table field) is a given one OR those which has a given meta value (postmeda table field).
If "author" was a meta value, I know I could use a meta_query to achieve it. The thing here is that it is not... so I think I cannot use the "author" field within a meta_query and use the "relation" key.
I'm looking for something like:
$args = array(
'post_type' => array('post'),
'orderby' => 'ASC',
'order' => 'date',
'meta_query' => array(
'relation' => 'OR',
array(
'relation' => 'AND',
array(
'field' => 'author',
'value' => $author_id,
'compare' => '==',
),
array(
'key' => '_meta_field_name',
'compare' => 'NOT EXISTS',
),
),
array(
'relation' => 'AND',
array(
'key' => '_meta_field_name',
'compare' => 'EXISTS',
),
array(
'key' => '_meta_field_name',
'value' => $meta_field_value,
'compare' => '==',
),
),
),
);
$data = new WP_Query( $args );
Any suggestion on how to achieve that using WP_Query?
Thanks!
You might like to try an approach like this one instead. The idea is to query the two conditions you want to search for, then merge the two queries into one finished product.
//Get posts with the author you're looking for
$args1 = array(
'author_name' => 'testuser', //or 'author' => $author_id or something else
);
$data1 = get_posts( $args1 );
//Get posts with the meta data you're looking for
$args2 = array(
'meta_query' => array(
array(
'key' => 'meta_field_name',
'compare' => 'EXISTS',
),
array(
'key' => 'meta_field_name',
'value' => $meta_field_value,
'compare' => '==',
),
),
);
$data2 = get_posts( $args2 );
//Merge both arrays
$allData = array_merge( $data1, $data2 );
//Get just the IDs of all the posts found, while also dropping any duplicates
$postIDs = array_unique( wp_list_pluck( $allData, 'ID' ) );
//Do a new query with these IDs to get a properly sorted array of post objects
$args3 = array(
'post__in' => $postIDs,
'order' => 'ASC',
'orderby' => 'date',
);
$finalAnswer = get_posts( $args3 ); //This is your array of post objects. Ta-Da!
I use ACF plugin on my wordpress site and I want to code custom research.
I have many products and I want to display products which contain the searched word.
I do my query like this :
$args = array(
'post_type' => 'product',
'meta_key' => 'brand',
'meta_value' => $word,
'compare' => 'LIKE');
$the_query = new WP_Query($args);
But this display only products with the brand which exactly matches with $word.
for exemple if I search "yan" I want to display products with the brand "YANMAR", "POLYAN", "TRYANPO", etc.
How to do this please ?
Thank you and have a good day !
Try below code.
$args = array(
'post_type' => 'product',
'post_status' => 'publish',
'posts_per_page' => -1,
'meta_query' => array(
array(
'key' => 'brand',
'value' => $word,
'compare' => 'LIKE'
)
)
);
$the_query = new WP_Query($args);
How to check efficiently if a given image of a Wordpress blog is already a post thumbnail (featured image) of any of the posts in the Wordpress blog.
Found a solution which seems to do:
function isPostThumbnail($imageId) {
$args = array(
'post_type' => 'post',
'posts_per_page' => 1,
'meta_query' => array(
array(
'key' => '_thumbnail_id',
'compare' => '=',
'value' => $imageId
),
)
);
return sizeof(get_posts( $args )) >0;
}
