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 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'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'd like some assistance modifying this code (source):
<?php
$args = array(
'post_type' => 'attachment',
'post_mime_type' => 'image',
'numberposts' => 4,
'post_status' => null,
'post_parent' => any, // any parent
);
$attachments = get_posts($args);
if ($attachments) {
foreach ($attachments as $post) {
setup_postdata($post);
the_attachment_link($post->ID, false);
}
}
?>
Right now, it's getting querying all the image attachments from my WP install and displaying the latest 4 as their thumbnail versions. My problem is that the_attachment_link only allows for it to link to either the full-size image or the attachment page of the image. I'd like it to link to the post (and I can guarantee that each image is only attached to 1 post, if that would be an issue/concern).
I've tried using other functions like wp_get_attachment_image and wp_get_attachment_link but they end up displaying nothing (and no error either). Any help please?
Here is your solution:
<?php
$args = array(
'post_type' => 'attachment',
'post_mime_type' => 'image',
'numberposts' => 4,
'post_status' => null,
'post_parent' => 'any', // any parent
);
$attachments = get_posts($args);
if ($attachments) {
foreach ($attachments as $post) {
setup_postdata($post);
?>
<?php echo wp_get_attachment_image($post->ID) ?>
<?php
}
}
?>
Make sure $post->post_parent has a value.
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' );
}
}
}
How would I retrieve attachments from all subpages of a specific Page ID?
Example:
SPECIFIC PAGE
Child (with attachments)
Child (with attachments)
Child (with attachments)
I'm currently using this code to retrieve all attachments site-wide, however I would like to limit this to only pull images from all children of a specific Page.
<?php
$args = array( 'post_type' => 'attachment', 'numberposts' => -1, 'post_status' => null, 'post_parent' => null );
$attachments = get_posts( $args );
if ($attachments) {
foreach ( $attachments as $post ) {
setup_postdata($post);
the_title();
the_attachment_link($post->ID, false);
the_excerpt();
}
}
?>
Almost there using this code as per Nick's suggestion below:
<?php
$mypages = get_pages('child_of=19');
foreach ( $mypages as $mypage ) {
$attachments = get_children(array('post_parent' => $mypage->ID, 'numberposts' => 1, 'post_type' => 'attachment', 'post_mime_type' => 'image', 'orderby' => 'rand'));
if ($attachments) {
foreach ( $attachments as $post ) {
setup_postdata($post);
the_title();
the_attachment_link($post->ID, false);
the_excerpt();
}
}
}
?>
However, there are two remaining issues:
Limiting the amount of total photos pulled. Using 'numberposts' only limits the amount of images pulled from each post
Randomization. Orderby => rand only randomizes the images within each post. I would like to randomly shuffle the order for everything.
Try using get_pages( $args )
<?php $args = array(
'child_of' => 'SPECIFIC PAGE',
'parent' => 'SPECIFIC PAGE',
'post_type' => 'attachment',
'post_status' => 'publish',
'numberposts' => -1
); ?>
Using child_of will get all children and grandchildren.
parent will limit this to just the children that have this as a parent. No grandchildren.
