Can I add ID to the $args array? I need to check if the key value pair custom field exists for a particular post. Now it checks if the key value pair exists in any post. Or do I need to perform the query and then check for my value in the returned array?
$args = array(
'post_type' => 'post',
'post_status' => 'publish',
'ID' => $_POST['post_id'],
'meta_query' => array(
array(
'key' => 'claim',
'value' => $user_ID
)
)
);
// perform the query
$query = new WP_Query( $args );
$vid_ids = $query->posts;
if ( empty( $vid_ids ) ) {
add_post_meta( $_POST['post_id'], 'claim', $user_ID );
}else{
echo "sorry";
}
Please reference the Codex entry for post/page parameters for WP_Query().
You can pass single post id with this
$query = new WP_Query( array( 'p' => 7 ) );
If you want to pass multiple post id's use
$myarray = array('100', '222');
$args = array(
'post_type' => 'post',
'post__in' => $myarray
);
// The Query
$the_query = new WP_Query( $args );
Use get_post_meta to get custom field value for your object.
$claims=get_post_meta($ID,'claim');
$exists=false;
if(count($claims)>0)
{
foreach($claims as $claim)
{
if($claim==$user_ID)
{
$exists=true;
break;
}
}
}
if(!$exists)
{
add_post_meta( $_POST['post_id'], 'claim', $user_ID );
}

This code does not set the object terms. Please help me sort out the issue. The code results in the posts list and doesn't set the terms.
I have checked the below data.
The query results in the list of post.
calculation part in the loop results in the value (lesser or greater than 0)
function set_expired_job_categories() {
global $post;
$current_time = time();
$taxonomy = 'current-status';
$job_expired_id = 368;
$job_ongoing_id = 367;
// Set our query arguments
$args = array(
'fields' => 'ids', // Only get post ID's to improve performance
'post_type' => 'job', // Post type
'post_status' => 'publish',
'posts_per_page' => -1,
'tax_query' => array(
'taxonomy' => 'current-status',
'field' => 'slug',
'terms' => array( 'ongoing' ),
),
);
$job_expiration_query = new WP_Query( $args );
// Check if we have posts to delete, if not, return false
if( $job_expiration_query->have_posts() ){
while( $job_expiration_query->have_posts() ){
$job_expiration_query->the_post();
$postid = get_the_ID();
$expire_timestamp = rwmb_meta( 'deadline_date' );
if ( $expire_timestamp ) {
$seconds_between = ( (int)$expire_timestamp - (int)$current_time );
if ( $seconds_between <= 0 ) {
wp_set_object_terms( $postid, (int)$job_expired_id, $taxonomy, true );
wp_remove_object_terms( $postid, (int)$job_ongoing_id, $taxonomy );
}
}
}wp_reset_postdata();
}
}
add_action( 'set_job_categories', 'set_expired_job_categories', 20, 2 );
As it is in the functions file, I need to set the global $wp_taxonomies to populate the taxonomies data initially. Also, instead of using the tag_ID, I have revised with the slug. These two changes helped to work out the code. The revised code is below for reference.
Thank you all for your efforts.
function set_expired_job_categories() {
global $post;
global $wp_taxonomies;
$current_time = time();
$taxonomy = 'current-status';
$job_expired_id = 'expired';
$job_ongoing_id = 'ongoing';
// Set our query arguments
$args = array(
'fields' => 'ids', // Only get post ID's to improve performance
'post_type' => 'job', // Post type
'post_status' => 'publish',
'posts_per_page' => -1,
'tax_query' => array(
'taxonomy' => 'current-status',
'field' => 'slug',
'terms' => array( 'ongoing' ),
),
);
$job_expiration_query = new WP_Query( $args );
// Check if we have posts to set categories, if not, return false
if( $job_expiration_query->have_posts() ){
while( $job_expiration_query->have_posts() ){
$job_expiration_query->the_post();
$postid = get_the_ID();
$expire_timestamp = rwmb_meta( 'deadline_date' );
if ( $expire_timestamp ) {
$seconds_between = ( (int)$expire_timestamp - (int)$current_time );
if ( $seconds_between >= 0 ) {
}else {
wp_set_object_terms( $postid, (int)$job_expired_id, $taxonomy, true );
wp_remove_object_terms( $postid, (int)$job_ongoing_id, $taxonomy );
}
}
}
wp_reset_postdata();
}
}
// hook it to low priority value, due to CPT and Taxonomies
add_action( 'set_job_categories', 'set_expired_job_categories', 20, 2 );

I have about 25,000 posts here (and rising). All of them under a Custom Post Type "lead".
Each post has meta information, including a variable called "uniqid".
this uniqid is a url parameter. now i need the post id where exactly this uniqid exists.
Now my question is if there is a way to speed up this determination.
I have tried 2 ways once a wp_query and get_results.
I ask because this function that determines the post id is always noted by plugin "query monitor" that it is slow.
These are the 2 approaches, both work. I just wonder if it is possible to speed up here?
The WP_Query solution.
$post_id = false;
$args = array(
'posts_per_page' => -1,
'post_type' => 'lead',
'fields' => 'ids',
'orderby' => 'date',
'order' => 'ASC',
'post_status' => 'publish',
'meta_key' => 'uniqid',
'meta_value' => $uniqid
);
$query = new WP_Query( $args );
if( $query->have_posts() ) {
while( $query->have_posts() ) {
$query->the_post();
// Get Post ID for return
$post_id = get_the_id();
// Break loop, when matching id was found
$uniqidGPM = get_post_meta( $post_id, 'uniqid' , true );
if($uniqidGPM == $uniqid) {
$post_found = true;
break;
}
}
}
wp_reset_postdata();
return $post_id;
The select get_results solution.
$post_id = false;
global $wpdb;
$selectQuery = "SELECT wp_wkdm_posts.ID FROM wp_wkdm_posts INNER JOIN wp_wkdm_postmeta ON ( wp_wkdm_posts.ID = wp_wkdm_postmeta.post_id ) WHERE 1=1 AND ( ( wp_wkdm_postmeta.meta_key = 'uniqid' AND wp_wkdm_postmeta.meta_value = '".$uniqid."' )) AND wp_wkdm_posts.post_type = 'lead' AND ((wp_wkdm_posts.post_status = 'publish')) GROUP BY wp_wkdm_posts.ID ORDER BY wp_wkdm_posts.post_date ASC";
$selectQueryResult = $wpdb->get_results($selectQuery);
if (empty($selectQueryResult)) {
return $post_id;
}else{
$post_id = $selectQueryResult[0]->ID;
return $post_id;
};
Please use this meta_query condition on the same query, it helps you.
$args = array(
'post_type' => 'lead',
'posts_per_page' => -1,
'post_status' => 'publish',
'meta_query' => array(
'key' => 'uniqid',
'value' => 'YOUR_VALUE'
)
);
$query = new WP_Query($args);
I have two custom post types with acf fields.
Custom Post_A, which has 2 fields - title / submitted
Custom Post_B, which has 2 fields - title / percent
Both Post_A and B have the same title (which is the logged in user's name) and they already exist.
When a field ‘submitted’ has the value ‘done’ in Post_A, I need to automatically update a ‘percent’ field with a value ‘50’ in Post_B.
I tried the following code but it doesn't update ‘50’ to Post_B.
Would you please correct my code?
$posts = get_posts(array(
'author' => get_current_user_id(),
'posts_per_page' => -1,
'post_type' => 'post_a',
'meta_key' => 'submitted',
'meta_value' => 'done'
));
$the_query = new WP_Query( $posts );
$the_count = count($the_query);
if($the_count>0) {
foreach ($the_query as $is_done){
$my_post = array();
$my_post['post_type'] = 'post_b';
$my_post['post_title'] = the_title();
// Update the post into the database
$field_key = "field_606cb546456343";
$value = "50";
update_field( $field_key, $value);
}
}
Thank you.
You can use save_post_{$post->post_type} action hook that will trigger on specific post type. check the below code.
function update_post_b( $post_id, $post, $update ){
$post_a_title = get_the_title( $post_id );
$posts = array(
'author' => get_current_user_id(),
'posts_per_page' => -1,
'post_type' => 'post_b'
);
$post_b = new WP_Query( $posts );
if( $post_b->have_posts() ){ while ( $post_b->have_posts() ) { $post_b->the_post();
if( $post_a_title == get_the_title() ){
update_post_meta( get_the_ID(), 'percent', 50 );
}
} }
}
add_action( 'save_post_post_a', 'update_post_b', 10, 3 );

save_post_{$post->post_type}
my first query is okay
$ids = [];
$novidades = get_posts( array(
'posts_per_page' => 4,
'meta_key' => 'meta-checkbox',
'meta_value' => 'yes'
) );
if ( count( $novidades ) ) {
foreach( $novidades as $novidade ) {
$ids[] = $novidade->ID;
}
}
//rest of my code is ok
but, i try post another post and ignore the first query, but don't work, list all post
$args2 = array(
'post_type' => 'post',
'posts__not_in' => $ids
);
$featured = new WP_Query($args2);
Can help me?
It's post__not_in. Remove the extra s from your code.
post__not_in (array) - use post ids. Specify post NOT to retrieve. If this is used in the same query as post__in, it will be ignored.
Your code should be:
$args2 = array(
'post_type' => 'post',
'post__not_in' => $ids,//<====extra 's' removed
);
$featured = new WP_Query($args2);
The wp_query below does not work when using the post_parent operator.
If I remove this option the query runs but when I add back in, it does not.
I have identified the post parent id from the category URL in the admin and it's definitely correct with 24 posts in that category.
the url for the category is wp-admin/term.php?taxonomy=category&tag_ID=2893&post_type=post&wp_http_referer=%2Fwp-admin%2Fedit-tags.php%3Ftaxonomy%3Dcategory
<?php
// WP_Query arguments
$args = array(
'post_parent' => '2893',
'post_type' => 'post',
//'post_status' => array( 'publish' ),
//'nopaging' => true,
// 'order' => 'ASC',
// 'orderby' => 'title'
);
// The Query
$sizes = new WP_Query( $args );
// The Loop
if ( $sizes->have_posts() ) {
while ( $sizes->have_posts() ) {
$sizes->the_title();
}
} else {
echo 'nothing here...';
}
// Restore original Post Data
wp_reset_postdata(); ?>
If you want to list pages that are tagged with a category term (by id) you will have to use 'category__in' => array() instead.
The post_parent argument is for getting pages ( or CPTs that are hierarchical ) where the ID passed is the page/post which is set as parent to other pages.
Example usage of getting posts tagged with category id:
$args = array(
'category__in' => array($cat_id_1, $cat_id_2) // Where $cat_id_x is an integer of the category ID (2893 in your case).
);
Pass the argument as an integer, not a string ;)
<?php
// WP_Query arguments.
$args = array(
'post_parent' => 2893, // This should be integer.
'post_type' => 'post',
// 'post_status' => array( 'publish' ),
// 'nopaging' => true,
// 'order' => 'ASC',
// 'orderby' => 'title',
);
// The Query.
$sizes = new WP_Query( $args );
// The Loop.
if ( $sizes->have_posts() ) {
while ( $sizes->have_posts() ) {
$sizes->the_title();
}
} else {
echo 'nothing here...';
}
// Restore original Post Data.
wp_reset_postdata();
