I've a post with post_format = video, in which the content are a video and a text (in the default editor). I need to display the video and the text separately. How can do it?
For now, I've this code:
global $post;
$tmp_post = $post;
$args = array(
'posts_per_page' => 1,
'post_type' => 'post',
'post_status' => 'publish',
'order' => 'DESC',
'tax_query' => array(
array(
'taxonomy' => 'post_format',
'field' => 'slug',
'terms' => array( 'post-format-video' ) // post format
)
)
);
$video_posts = get_posts( $args );
foreach ($video_posts as $post ) :
setup_postdata( $post );
echo get_the_title($post->ID);
// ------> Here what code for get the video?
// html
// ...
// ...
// ------> Here what code for get the text (if possible)?
endforeach;
$post = $tmp_post;
At the end I found a solution myself: I made a function that return the iframe for the first video inside the post with id $post_id:
function get_first_video_embed($post_id) {
$content = apply_filters('the_content', get_post_field('post_content', $post_id));
$iframes = get_media_embedded_in_content( $content, 'iframe' );
return $video_post_iframe = $iframes[0];
}

I'm using polylang plugin to having multi-languages website.
Using WooCommerce with polylang demands duplicating each product for each language, so assuming I have Hebrew and English, that means 2 duplications for each products.
It works fine with WooCommerce plugin, but when I'm displaying "related products" at the end of the product page, it's mixing products in English and Hebrew together.
I expect to filter the related product by website current language (if(get_locale() == 'en_US') - to check website current locale state, else will represent Hebrew).
Polylang functions
Here is what I have tried, but I got stuck on the part of filtering the product by language:
add_filter( 'woocommerce_product_related_posts', 'custom_related_products' );
function custom_related_products($product){
global $woocommerce;
// Meta query
$meta_query = array();
$meta_query[] = $woocommerce->query->visibility_meta_query();
$meta_query[] = $woocommerce->query->stock_status_meta_query();
$meta_query = array_filter( $meta_query );
// Get the posts
$related_posts = get_posts( array(
'orderby' => 'rand',
'posts_per_page' => '4',
'post_type' => 'product',
'fields' => 'ids',
'meta_query' => $meta_query
) );
if ( $related_posts->have_posts() ) {
while ( $related_posts->have_posts() ) : $related_posts->the_post();
if(pll_get_post_language(get_the_ID())){
//Not sure its the right approach for this..
}
endwhile;
}
$related_posts = array_diff( $related_posts, array( $product->id ), $product->get_upsells() );
return $related_posts;
}
How can I filter Woocommerce related product section by language?
Edit
So after a little bit of research and help in the comments I found out that 'lang' => 'en' argument does exist, but even when I use it, there is no change on related products language display.
Any ideas?
add_filter( 'woocommerce_product_related_posts', 'custom_related_products' );
function custom_related_products($product){
global $woocommerce;
// Meta query
$meta_query = array();
$meta_query[] = $woocommerce->query->visibility_meta_query();
$meta_query[] = $woocommerce->query->stock_status_meta_query();
$meta_query = array_filter( $meta_query );
// Get the posts
$related_posts = get_posts( array(
'orderby' => 'rand',
'posts_per_page' => '4',
'post_type' => 'product',
'fields' => 'ids',
'meta_query' => $meta_query,
'suppress_filters' => false
) );
if ( $related_posts->have_posts() ) {
while ( $related_posts->have_posts() ) : $related_posts->the_post();
if(pll_get_post_language(get_the_ID())){
//Not sure its the right approach for this..
}
endwhile;
}
$related_posts = array_diff( $related_posts, array( $product->id ), $product->get_upsells() );
return $related_posts;
}
suppress_filters There is a way to make get_posts cache the results however, the suppress_filters option is true by default, but if you set it to false, the caching mechanisms inside WordPress will do their work, and results will be saved for later.
You can try this code:
$related_posts = get_posts( array(
'orderby' => 'rand',
'posts_per_page' => '4',
'post_type' => 'product',
'meta_query' => $meta_query,
'lang' => 'en'
) );
if ($related_posts) {
foreach ($related_posts as $post) {
setup_postdata($post);
// something like <li><?php the_title(); ?></li>
}
}
wp_reset_postdata();
This code correctly returns code in selected language on my site
While working on a custom WordPress REST Api end point to fetch post by selected language or device language, this worked. See if it can help you out.
function mycustomplugin_posts($params) {
// get the url params
$page = $params->get_param('page') ? $params->get_param('page') : 0;
$per_page = $params->get_param('per_page') ? $params->get_param('per_page') : 10;
$offset = $params->get_param('offset') ? $params->get_param('offset') : 0;
$order = $params->get_param('order') ? $params->get_param('order') : 'desc';
$order_by = $params->get_param('order_by') ? $params->get_param('order_by') : 'date';
$lang = array_search($params->get_param('lang'),polylang_json_api_languages(), true) ? $params->get_param('lang') : pll_default_language();
$args = [
'post_type' => 'post',
'page' => $page,
'numberposts' => $per_page,
'offset' => $offset,
'order' => $order,
'orderby' => $order_by,
'tax_query' => [
[
'taxonomy' => 'language',
'field' => 'slug',
'terms' => $lang
]
]
];
$posts = get_posts($args);
$data = [];
$i = 0;
foreach($posts as $post) {
// Extract the post data
$data[$i]['id'] = $post->ID;
$data[$i]['title'] = $post->post_title;
$data[$i]['content'] = $post->post_content;
$data[$i]['excerpt'] = e42_the_short_content($post->post_content, 300);
$data[$i]['slug'] = $post->post_name;
$data[$i]['date'] = $post->post_date;
$data[$i]['link'] = get_permalink($post->ID);
$data[$i]['author'] = get_the_author_meta('display_name', $post->post_author);
$data[$i]['categories'] = array();
$data[$i]['featured_image']['thumbnail'] = get_the_post_thumbnail_url($post->ID, 'thumbnail');
$data[$i]['featured_image']['medium'] = get_the_post_thumbnail_url($post->ID, 'medium');
$data[$i]['featured_image']['large'] = get_the_post_thumbnail_url($post->ID, 'large');
foreach(get_the_category($post->ID) as $category){
array_push($data[$i]['categories'],$category->term_id);
}
$i++;
}
// Create the response object
$response = new WP_REST_Response( $data );
// Add a custom status code
$response->set_status( 200 );
return $response;
}
/plugins/woocommerce/templates/single-product/related.php
Move this to child theme
yourtheme/woocommerce/single-product/related.php
And add the following line to the foreach loop
if (pll_current_language()!=pll_get_post_language($post_object->ID)) {
continue;
}
Basically if current language does not match product language we skip over it.
I am adding an image from media in every single post that are created.
To get the attached image and url of that post, I am implementing this code:
$args = array(
'post_type' => 'attachment',
'post_mime_type' => 'image',
'numberposts' => 5,
'post_status' => null,
'post_parent' => 'any', // any parent
);
$attachments = get_posts($args);
if ( $attachments ) {
foreach ( $attachments as $attachment ) {
setup_postdata($attachment);
$v =$attachment->ID;
$imageurl = wp_get_attachment_url($v);
$postlink = get_permalink($v);
}
The above code works fine for retrieving image url. My question is how do I pass post ID in get_permalink() to make sure that I get link of that post. I know that passing $v in get_permalink() is wrong.
There is a code spinet to print attachment posts.
$args = array(
'post_type' => 'attachment',
'post_mime_type' => 'image',
'posts_per_page' => 5,
'post_status' => 'inherit',
'post_parent' => 'any', // any parent
);
$loop = new WP_Query($args);
while ( $loop->have_posts() ) : $loop->the_post();
global $post;
echo '<pre>';
print_r($post);
echo '</pre>';
endwhile; wp_reset_query();
Its depending which ID you are looking for inside the loop
$post-ID : That return the post ID for attachment post.
$post->post_parent : It returns the current attachment post parent post ID.
I am fairly new to Wordpress and I am trying to make a function that loads images under a media category. The media category has a slug that I want to pass into the function. If there is an easier way to do this please let me know. Below is my code so far:
Functions.php
function get_image_by_slug($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 using below code to get all the attachments assign to my custom post type..but now i want to get the post id within the loop..how can i do that??
$query = new WP_Query(
array(
'post_type' => 'portfolio', // adjust your custom post type name here
'posts_per_page' => -1,
'fields' => 'ids'
)
);
$image_query = new WP_Query(
array(
'post_type' => 'attachment',
'post_status' => 'inherit',
'post_mime_type' => 'image',
'posts_per_page' => -1,
'post_parent__in' => $query->posts,
'order' => 'DESC'
)
);
if( $image_query->have_posts() ){
while( $image_query->have_posts() ) {
$image_query->the_post();
$imgurl = wp_get_attachment_url( get_the_ID() );
if(!empty($output)) $output = 'Sorry, no attachments found.';
$output .= '<img src="'.$imgurl.'">';
echo $output;
}
Thanks!
Depending on which ID you are looking for inside the loop, you can do the following
$post-ID -> Returns the post ID from the attachment post being displayed
$post->post_parent -> Returns the current attachment post parent post ID
I´m trying to get the post thumbnail and another attached image from the last post of a custom post type (called parceiros-e-links).
What I got is to get all posts with images and show them... but I need to show only the last post and show it with two images (the_post_thumbnail and the wp_get_attachment_image)
Here is my current code:
<?php
$query = new WP_Query( array( 'post_type' => 'parceiros-e-links', 'posts_per_page' => -1, 'orderby' => 'date', 'order' => 'DESC' ) ); //the first loop where I filter the posts from custom post type and by date
if( $query->have_posts() ){
while($query->have_posts()){
$query->the_post();
$image_query = new WP_Query( array( 'post_type' => 'attachment', 'post_status' => 'inherit', 'post_mime_type' => 'image', 'posts_per_page' => 2, 'post_parent' => get_the_ID() ) ); //the second loop where I filter the posts with attachments and limit to two
while( $image_query->have_posts() ) { $image_query->the_post();
//code below prints the two attachments: thumbnail and another one.
if(has_post_thumbnail()){
the_post_thumbnail('home-parceiros');
}
echo wp_get_attachment_image( get_the_ID(), 'home-parceiros-foto' );
}
}
}
?>
I already spent many hours searching similar situations and trying to filter this code but I'm without ideas... Because if I limit the query's first posts_per_page to 1, if the most recent post doesn't has an attachment, no images will be printed!
Any clues about how to limit the number of posts with attachments inside a custom post type?
Thanks!
Your mistakes was at the_post_thumbnail('home-parceiros'); and echo wp_get_attachment_image( get_the_ID(), 'home-parceiros-foto' ); Read about the correct attributes given for this two functions here:
http://codex.wordpress.org/Function_Reference/the_post_thumbnail
http://codex.wordpress.org/Function_Reference/wp_get_attachment_image
Here is my suggestion:
$query = new WP_Query(
array(
'post_type' => 'parceiros-e-links',
'posts_per_page' => 1,
'orderby' => 'date',
'order' => 'DESC'
)
);
if($query->have_posts()) :
while($query->have_posts()) : $query->the_post();
if(has_post_thumbnail()) : the_post_thumbnail(); endif;
$args = array(
'post_type' => 'attachment',
'numberposts' => 1,
'post_status' => null,
'post_parent' => $post->ID
);
$attachments = get_posts( $args );
if ( $attachments ) {
foreach ( $attachments as $attachment ) {
echo wp_get_attachment_image( $attachment->ID, 'full' );
}
}
endwhile;
endif;
Please let me know :)
Example #2 updated:
$query = new WP_Query( array( 'post_type' => 'parceiros-e-links', 'posts_per_page' => 1, 'orderby' => 'date', 'order' => 'DESC' ) ); //the first loop where I filter the posts from custom post type and by date
if( $query->have_posts() ){
while($query->have_posts()){
$query->the_post();
$image_query = new WP_Query( array( 'post_type' => 'attachment', 'post_status' => 'inherit', 'post_mime_type' => 'image', 'posts_per_page' => 2, 'post_parent' => get_the_ID() ) ); //the second loop where I filter the posts with attachments and limit to two
while( $image_query->have_posts() ) { $image_query->the_post();
//code below prints the two attachments: thumbnail and another one.
if(has_post_thumbnail()){
the_post_thumbnail('home-parceiros');
}
echo wp_get_attachment_image( get_the_ID(), 'home-parceiros-foto' );
