I'm using Wordpress with the Advanced Custom Fields Pro plugin and I'm trying to get all the posts that have a date field that is after today's date. I looked at this example https://www.advancedcustomfields.com/resources/date-picker/ and that works fine except that my field is a subfield of a repeater field. And I have some trouble making a meta query for that. I tried using _%_ for the subfield but then I read here https://support.advancedcustomfields.com/forums/topic/meta_query-for-a-group-field-sub-field/ that I can just use an underscore for the subfield. But posts still aren't coming up with any results. I tried checking the date from just a single post and it appears to be working correctly. I also read here advancedcustomfields.com/resources/date-picker that the date is always stored as Ymd in the database. I tried doing it with another field that isn't a subfield and that worked, so the problem lies with the subfield I think 'key' => 'date_startdate',
I am using the date picker as a subfield.
function do_get_upcoming($atts = [])
{
$defaultLimit = 8;
$limit = $atts["limit"] != null ? $atts["limit"] : $defaultLimit;
$today = date('Ymd');
$posts = get_posts(array(
'numberposts' => $limit,
'post_type' => 'events',
'meta_query' => array(
array(
'key' => 'date_startdate',
'value' => $today,
‘type’ => ‘DATE’
'compare' => '>',
)
),
));
echo count($posts);
}
add_shortcode('get_upcoming','do_get_upcoming');

I found the solution. Subfields can be accessed by adding _0_ so you'll get 'key' => 'date_0_startdate'

I have two custom post types: venue and event.
Lets say that both post types have the _location meta key (custom field) and both of them also have music-genre taxonomy.
Event also has _association meta key which contains ID of the associated venue.
Now Querying events by mentioned taxonomy and meta field is very easily done like this:
$query = new WP_Query([
'post_type' => 'event',
'tax_query' => [
[
'taxonomy' => 'music-genre',
'field' => 'slug',
'terms' => ['house', 'jazz', 'rock']
]
],
'meta_query' => [
[
'key' => '_location',
'value' => ['Miami', 'Ibiza', 'Zrce'],
'compare' => 'IN'
]
]
]);
$posts = $query->posts;
But I want to also get events with empty '_location' field IF his parent/associated post (ID stored under _association meta key) has expected value. Same thing for taxonomies - Music Genre in this example. If event doesn't have associated "Jazz" music genre, but his associated post has it then it should be returned by WP_Query.
So basically I want to inherit meta values and taxonomies from associated post if they doesn't exists or are empty.
I hope you can understand what I want to achieve well... otherwise please ask for further explanation.
In case anyone is wondering im using Carbon Fields library for custom fields.
Also my project is much more complicated, but everything was simplified for this question, so performance matters a lot.
Trying to understand... are you looking for this 'hide_empty' => false?
Looking for a point in the right direction, i've been working on an events plugin for a site, quite a simple plugin, adds a custom post type called events, adds some custom taxonomies, used ACF to add the fields to the CPT.
But I need to add 'start date and time', and 'end date and time' fields to it in a way that I'll be able to sort by start date/time in the admin side, and be able to sort by them when I query the posts as well.
I thought I might be able to do this with the ACF date/time field, but it's just not playing ball. Any ideas?
If i'm understanding correctly, you want to sort your results by a meta value right? that meta value being the date/time field. In your loop, you may want to try out something along the lines of:
$your_custom_query = new WP_Query( array(
'meta_query' => array(
'relation' => 'AND',
'date_clause' => array(
'key' => 'date_time_meta_key_here',
'compare' => 'EXISTS',
)
),
'orderby' => 'date_clause'
));

I used wordpress to make a website with some custom types. The problem is that i need to implement a filter for these types and I have some questions about the plugins that i'm using for this project:
For to make custom types and views I'm using Types and Views plugins for wordpress.
I made a new custom type with some fields (title, price, some selectors, ...) and I need to filter all the information ordering the results following 2 criterias. I don't know if is it possible to do so using the Views/Types plugin.
I also need to filter the fields of the filter. For example, if i have 2 fields one called Countries and other called Cities, if i select Spain in countries I should see only spanish cities in the second field.
Any idea if i can do that using Types and Views plugins? is there any other plugin?
Thanks in advance!
Any good plugin will save the custom fields as post-meta. You need to find out what the key is for the field you are trying to use as a filter. Once you have that you can use a simple meta query to get the posts you need:
$args = array(
'post_type' => 'post', // The post type
'posts_per_page' => -1, // Get all posts
'orderby' => 'rand', // Random order, also can use 'post_date' or 'post_title'
'order' => 'ASC', // Direction of sort
'meta_key' => 'my_meta_key', // Whatever your key is
'meta_query' => array(
array(
'key' => 'my_meta_key', // Whatever your key is
'value' => 'foo' // What it should be
'compare' => 'IN', // How to compare the value to the stored value
)
)
);
$query = new WP_Query($args); // The query
Here is more on the Wordpress codex.
I need to modify or create a WP_Query that will search for a search term in both the post title OR a custom field (called 'my_field').
I have been reading and trying for hours, but I am right back to this code (below) which, alas, only searches in 'my_field' and does not take the post_title into account.
function my_pre_get_posts_2( $query ) {
if ( is_admin() && $query->is_main_query() && $query->query['post_type'] === 'post' && isset($query->query['s']) ) {
$search_word = $query->query['s'];
$args = array(
//'s' => $search_word, //If I include this line, the WP query seems to AND post_title and my_field. If I comment out this line, the WP query only searches in my_field. (I need WP to OR post_title and my_field.)
'post_type' => 'post',
'meta_query' => array(
'relation' => 'OR',
array(
'key' => 'my_field',
'value' => $search_word,
'compare' => 'IN'
),
array(
'key' => 'post_title',
'value' => $search_word,
'compare' => 'IN',
)
)
);
//$query = new WP_Query( $args ); //Need to modify the existing WP_Query
$query->init();
$query->parse_query($args);
}
}
add_action( 'pre_get_posts', 'my_pre_get_posts_2' );
The reason I need to do this is because I need to modify the behaviour of the the 'Search Posts' button in the 'All Posts' (admin) page so that whatever the admin user searches for, it will return the posts that have a matching post title OR my_field value.
To do an OR search, I tried merging two separate WP_Query results as shown here - https://wordpress.stackexchange.com/questions/55519/can-i-merge-2-new-wp-queryvariable-s - in guidod's answer. That wasn't a great solution though, and resulted in erratic behaviour.
The correct solution I found was to modify the query using the WP Custom Query as shown in the code (which requires some modifications) here - http://codex.wordpress.org/Custom_Queries .
I am working on a slider where I will show some contents(featured image and excerpt) pulled from both posts and pages. I want to filter the posts/pages by a custom field called 'slider'!
So if there are some pages and posts with 'slider' custom field only those will appear in the slider. Is it possible in wordpress? If it is then how?
Some guidance will be appreciated!
What you're looking for is the class called WP_Query, has got a detailed explanation in the Codex. Take a look at the post_type argument which accepts an array, thus you can give it a array( 'post', 'page' ) or any other post types that you want to fetch.
Now the meta fetch could be done in two ways, either via the new meta_query argument (from 3.1 onwards I believe) or meta_key and meta_value which are deprecated since 3.1.
Here's a rough example (haven't checked if this works):
$sider_posts = new WP_Query( array(
'post_type' => array( 'post', 'page' ),
'meta_query' => array(
array(
'key' => 'slider',
'value' => 'yes',
'compare' => '='
)
)
) );
while ( $slider_posts->have_posts() ) {
$slider_posts->the_posts();
// output the slide here
}
Hope that makes sense. Cheers!
