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

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() ) {
$sizes->the_title();
}
} else {
echo 'nothing here...';
}
// Restore original Post Data.
wp_reset_postdata();
I have this code
function display_categoria($args) {
$query = new WP_Query(array(
'post_type' => 'job_listing',
'post_status' => 'publish',
'posts_per_page' => 5
));
while ($query->have_posts()) {
echo $query->the_post();
$id=get_the_id();
echo $query1=get_permalink();
}
wp_reset_query();
}
add_shortcode( 'este', 'display_categoria' );
in theory i can solve it placing in the loop
if ( has_post_thumbnail() ) {
the_post_thumbnail();
}
but many entries not have a thumbnail (featured images), Can understand?
This should retrieve the url of the first image for each post. Insert it after the "$id=get_the_id();" line
$args = array(
'post_type' => 'attachment',
'post_mime_type' => 'image',
'posts_per_page' => -1,
'post_status' => null,
'post_parent' => $id
);
$images = get_posts( $args );
if ( $images ) {
$first_image_id = $images[0];
//do something with the image
wp_reset_postdata();
}
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 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' );
