I need to print another shortcode when the posts count is 0
any code I add to this code return a fatal error
add_shortcode('reviews_total', 'reviews_total_func');
function reviews_total_func()
{
global $post;
$args = array(
'posts_per_page' => -1,
'post_type' => 'testimonial',
'meta_key' => '_wpcf_belongs_' . $post->post_type . '_id',
'meta_value' => $post->ID,
);
$child_posts = get_posts($args);
return count($child_posts);
}
I need to view another shortcode if count($child_posts) = 0
Assuming the sole purpose of this shortcode is to output the number of posts, why not check for that prior to returning the value?
Example:
add_shortcode('reviews_total', 'reviews_total_func');
function reviews_total_func()
{
global $post;
$args = array(
'posts_per_page' => -1,
'post_type' => 'testimonial',
'meta_key' => '_wpcf_belongs_' . $post->post_type . '_id',
'meta_value' => $post->ID,
);
$child_posts = get_posts($args);
if(count($child_posts) > 0)
return count($child_posts);
else
return "Your custom, alternate zero-posts text";
}
Execute another shortcode with the function do_shortcode
add_shortcode('reviews_total', 'reviews_total_func');
function reviews_total_func() {
global $post;
$args = array(
'posts_per_page' => -1,
'post_type' => 'testimonial',
'meta_key' => '_wpcf_belongs_' . $post->post_type . '_id',
'meta_value' => $post->ID,
);
$child_posts = get_posts($args);
if(count($child_posts) > 0)
return count($child_posts);
return do_shortcode( '[my-short-code]' );
}

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);
Is it possible to Published all Draft Posts using SQL or Function code? I tried using this code in my function file, but not works.
add_action('admin_init','wpse_244394');
function wpse_244394(){
$args = array('post_type'=> 'post',
'post_status' => 'draft',
'posts_per_page'=>-1
);
$draft_posts = get_posts($args);
foreach($draft_posts as $post_to_publish){
$query = array(
'ID' => $post_to_publish->ID,
'post_status' => 'publish',
);
wp_update_post( $query, true );
}
}
try to use "wp_publish_post( $post_id )" instead of "wp_update_post".
add_action('admin_init','wpse_244394');
function wpse_244394(){
$args = array('post_type'=> 'post',
'post_status' => 'draft',
'posts_per_page'=>-1
);
$draft_posts = get_posts($args);
foreach($draft_posts as $post_to_publish){
wp_publish_post( $post_to_publish->ID );
}
}
I am fairly new to Wordpress and I am trying to make a function that loads images under a media category. The media category has a slug that I want to pass into the function. If there is an easier way to do this please let me know. Below is my code so far:
Functions.php
function get_image_by_slug($slug) {
$query_images_args = array(
'post_type' => 'attachment',
'post_mime_type' =>'image',
'post_status' => 'inherit',
'posts_per_page' => -1,
'tax_query' => array(
array(
'taxonomy' => 'attachment_category',
'field' => 'slug',
'terms' => $slug,
),
),
);
$query_images = new WP_Query( $query_images_args );
$images = array();
foreach ( $query_images->posts as $image) {
$images[]= $image->guid;
}
return $images;
}
function display_image_by_slug() {
$imgs = get_image_by_slug($slug);
$html = '<ul class="list-inline">';
foreach($imgs as $img) {
$html .= '<li><img src="' . $img . '" alt="" /></li>';
}
$html .= '</ul>';
return $html;
}
add_filter('display_slugs','display_image_by_slug');
In page
<?php apply_filter('display slugs', 'test_slug');?>
An attachment of image or file is just a post with the post_status = inherit and the post_type = attachment and it is saved into the wp_post & wp_postmeta , so can be queried with WP_Query or get_posts.
Note: The slug (post_name) is unique per post type.
You have to pass your slug in the query by replacing YOUR-SLUG in this place. &name=YOUR-SLUG
$_head = get_posts('post_type=attachment&name=YOUR-SLUG&posts_per_page=1&post_status=inherit');
$header = $_head ? array_pop($_head) : null;
$header_url = $header ? wp_get_attachment_url($header->ID) : '';
Another Method you can build your own custom function with the help that i have provided below.
function get_attachment_url_by_slug( $slug ) {
$args = array(
'post_type' => 'attachment',
'name' => sanitize_title($slug),
'posts_per_page' => 1,
'post_status' => 'inherit',
);
$_head = get_posts( $args );
$header = $_head ? array_pop($_head) : null;
return $header ? wp_get_attachment_url($header->ID) : '';
and then you can call using this function.
$header_url = get_attachment_url_by_slug('YOUR-SLUG');
So after looking around the Wordpress docs and understanding Naresh's answer I was able to come up with my own answer. Here it is...
$id = 'YOUR SLUG';
$args = array(
'post_type' => 'attachment',
'post_status' => 'any',
'posts_per_page' => -1,
'tax_query' => array(
array(
'taxonomy' => 'media_category', // your taxonomy
'field' => 'slug',
'terms' => $id // term id (id of the media category)
)
)
);
$the_query = new WP_Query( $args );
if ( $the_query->have_posts() ) {
while ( $the_query->have_posts() ) {
$the_query->the_post();
echo '<li>'. wp_get_attachment_image( get_the_ID() );
if(empty_content(get_the_content())){
echo '<p>' . get_the_excerpt() . '</p></li>';
} else {
echo '<p>'.get_the_excerpt().'</p></li>';
}
}
} else {
// no attachments found
}
wp_reset_postdata();
I'm an android developer. I made a php file on my host and I include wp-blog-header.php . I used this file as a web service.
In the my app, there is a search part and I get term as String and category as id of user and send them to my php file .
now, I would like to search in post titles and return titles and ids of what user want.
function customSearch($term,$category){
.
.
.
}
I used prepare functions to get posts like below function, but I cannot find any function to search only in post titles.
function getLastItems()
{
$args = array(
'numberposts' => 5,
'offset' => 0,
'category' => 0,
'orderby' => 'post_date',
'order' => 'DESC',
'post_type' => 'post',
'post_status' => 'publish',
'suppress_filters' => true );
$recent_posts = wp_get_recent_posts( $args, ARRAY_A );
$mjson = array();
foreach( $recent_posts as $recent ){
$thumb = wp_get_attachment_image_src( get_post_thumbnail_id($recent['ID']), array(400,300) );
$url_img = $thumb['0'];
$marr = array(
'id'=>$recent["ID"],
'title'=>$recent["post_title"],
'img'=>$url_img
);
array_push($mjson,$marr);
}
return $mjson ;
}//end get last items
I don't understand your search part, but your question about to search in only title , this answer will do for you.
Add filter to search only in title, before search.
Remove Filter after search.
if you want to search in title, just add below to args.
function search_by_title( $search, $wp_query ) {
if ( ! empty( $search ) && ! empty( $wp_query->query_vars['search_terms'] ) ) {
global $wpdb;
$q = $wp_query->query_vars;
$n = ! empty( $q['exact'] ) ? '' : '%';
$search = array();
foreach ( ( array ) $q['search_terms'] as $term )
$search[] = $wpdb->prepare( "$wpdb->posts.post_title LIKE %s", $n . $wpdb->esc_like( $term ) . $n );
if ( ! is_user_logged_in() )
$search[] = "$wpdb->posts.post_password = ''";
$search = ' AND ' . implode( ' AND ', $search );
}
return $search;
}
$args = array(
's' => 'search string',
'numberposts' => 5,
'offset' => 0,
'category' => 0,
'orderby' => 'post_date',
'order' => 'DESC',
'post_type' => 'post',
'post_status' => 'publish',
'suppress_filters' => true);
add_filter( 'posts_search', 'search_by_title', 10, 2 );
$recent_posts = wp_get_recent_posts($args, ARRAY_A);
remove_filter( 'posts_search', 'search_by_title', 500 );
foreach($recent_posts as $posts) {
// your custom code here
}
