I trying to use wp_playlist_shortcode for creating playlist with audio-files from all blog posts.
In official documentation i saw this parameter:
'ids'
(array) Create a playlist out of these explicit attachment IDs. If empty, a playlist will be created from all $type attachments of $id. Default empty.
I trying this code, and its doesn't working:
$attch_id = array('76', '73', '70', '67');
wp_playlist_shortcode( array( 'ids' => '$attch_id' );
How to create playlist with audio-files from all blog posts? Now i use this code, but it is a not playlist.
$audios = array( 'post_type' => 'attachment', 'posts_per_page' => -1, 'post_status' => null, 'post_parent' => null, 'post_mime_type' => 'audio/mpeg' );
$attachments = get_posts( $audios );
if ($attachments) {
foreach ( $attachments as $post ) {
setup_postdata($post);
$media_url = $post->guid;
$media_title = $post->post_title;
echo wp_audio_shortcode( array( 'src' => $media_url) );
echo '<p>' . $media_title . '</p>';
// print_r($media_url);
}
}
wp_reset_postdata();

I tried to insert a post using the wp_insert_post function in the functions.php file, the post successfully inserted, but not for the attachment for featured image.
Anyone can help on this, what's wrong with my code below:
$post_if = $wpdb->get_var("SELECT count(post_title) FROM $wpdb->posts WHERE post_title like '$title'");
if($post_if < 1){
//coded
$new_post = array(
'post_title' => $title,
'post_content' => $contents,
'post_status' => 'publish',
'post_author' => 1,
'post_type' => 'post'
);
$post_id = wp_insert_post($new_post);
$image = "https://fake.org/image.jpg";
$media = media_sideload_image($image, $post_id); //$post_id from wp_insert_post
// therefore we must find it so we can set it as featured ID
if(!empty($media) && !is_wp_error($media)){
$args = array(
'post_type' => 'attachment',
'posts_per_page' => -1,
'post_status' => 'any',
'post_parent' => $post_id
);
// reference new image to set as featured
$attachments = get_posts($args);
if(isset($attachments) && is_array($attachments)){
foreach($attachments as $attachment){
// grab source of full size images (so no 300x150 nonsense in path)
$image = wp_get_attachment_image_src($attachment->ID, 'full');
// determine if in the $media image we created, the string of the URL exists
if(strpos($media, $image[0]) !== false){
// if so, we found our image. set it as thumbnail
set_post_thumbnail($post_id, $attachment->ID);
// only want one image
break;
}
}
}
}
I tried so many tutorials, I found over the web, nothing to work.
Please any one has experienced with this can share a solution.
Big Thanks
You would need to set the "featured image" first and then try to query it. You tried to do the opposite. Also set the parent id in the wp_insert_attachment function not in the arguments.
So try this code:
$new_post = array(
'post_title' => $title,
'post_content' => $contents,
'post_status' => 'publish',
'post_author' => 1,
'post_type' => 'post'
);
$post_id = wp_insert_post($new_post);
$image = "https://fake.org/image.jpg";
$attachment_file_type = wp_check_filetype(basename($image), null);
$wp_upload_dir = wp_upload_dir();
$attachment_args = array(
'guid' => $wp_upload_dir['url'] . '/' . basename($image),
'post_title' => preg_replace('/\.[^.]+$/', '', basename($image)),
'post_mime_type' => $attachment_file_type['type']
);
$attachment_id = wp_insert_attachment($attachment_args, $image, $post_id);
require_once(ABSPATH . 'wp-admin/includes/image.php');
$attachment_meta_data = wp_generate_attachment_metadata($attachment_id, $image);
wp_update_attachment_metadata($attachment_id, $attachment_meta_data);
set_post_thumbnail($post_id, $attachment_id);
Here's the documentation page for
wp_insert_attachment

I am using the code below (simplified) to display a list of the last 10 comments:
<?php
$args = array(
'post_type' => 'tarefa',
'number' => '10',
'order' => 'DESC',
'orderby' => 'comment_date',
//'meta_key' => 'field_name',
//'meta_value' => 'field_value',
);
$comments_query = new WP_Comment_Query;
$comments = $comments_query->query( $args );
foreach ( $comments as $comment ) {
echo '<p>';
echo get_the_title($comment->comment_post_ID) . '<br>'; //post title
echo $comment->comment_content; // comment content
echo '</p>';
};
?>
Question:
Well, meta_key and meta_value seem to be associated to comment_meta... But in my case, I have to display comments based on post_meta key and value.
Any sugestions?
You can try this code.
You need to add a query for posts to get array of post ides with meta key.
Then use that array into comments query argument.
//QUERY FOR POSTS WITH META KEY AND VALUE (META QUERY)
$post_args = array(
'post_type' => 'post',
'meta_key' => 'meta key',//Meta key of post
'meta_value' => 'meta value',//String or Numeric value
'meta_compare' => '=',
);
$post_query = new WP_Query( $post_args );
$posts_array= array();
if ( $post_query->have_posts() ) {
while ( $post_query->have_posts() ) {
$post_query->the_post();
$posts_array[] = get_the_ID(); //Array of post ids
}
wp_reset_postdata();
}
//YOUR COMMENT ARGS SHOULD BE THIS
$args = array(
'post_type' => 'tarefa',
'number' => '10',
'order' => 'DESC',
'orderby' => 'comment_date',
'post__in' => $posts_array, //THIS IS THE ARRAY OF POST IDS WITH META QUERY
);
Try this , then let me know the result.
My first question here at Stackoverflow and that worked perfectly.
Thank you very much, Souvik!
Below the final result (simplified):
$post_args = array(
'post_type' => 'tarefa',
'posts_per_page' => -1,
'meta_key' => 'field_name',
'meta_value' => 'field_value',
);
$post_query = new WP_Query( $post_args );
$posts_array= array();
if ( $post_query->have_posts() ) {
while ( $post_query->have_posts() ) {
$post_query->the_post();
$posts_array[] = get_the_ID(); //Array of post ids
}
wp_reset_postdata();
}
//YOUR COMMENT ARGS SHOULD BE THIS
$args = array(
'number' => '30',
'order' => 'DESC',
'orderby' => 'comment_date',
'post__in' => $posts_array, //THIS IS THE ARRAY OF POST IDS WITH META QUERY
);
$comments_query = new WP_Comment_Query;
$comments = $comments_query->query( $args );
foreach ( $comments as $comment ) {
echo '<p>';
echo get_the_title($comment->comment_post_ID) . '<br>'; //post title
echo $comment->comment_content; // comment content
echo '</p>';
};
I was trying to create shortcode for custom taxonomy terms dynamically. But failing to do so.
Suppose, if there is a term called "wordpress" then I should be able to query all the posts associated with that term via shortcode.
To be more precise, suppose if there is a taxonomy called 'event' and under that taxonomy there are multiple terms. So, I was trying to query posts under each of the term via shortcode of each of the term.
Here is what I tried:
function wordpress_recent_post( $atts, $content ) {
$a = shortcode_atts( array(
'cat' => '',
), $atts );
$args = array(
'posts_per_page' => 1,
'offset' => 0,
'category_name' => $a['cat'],
'orderby' => 'post_date',
'order' => 'DESC',
'post_type' => 'post',
'post_status' => 'publish',
'ignore_sticky_posts' => true,
);
$recent_posts = new WP_Query( $args );
ob_start();
if ( ! $recent_posts-> have_posts() ) {
return 'No Posts Found for ' . $a['cat'];
}
while ( $recent_posts->have_posts() ) {
$recent_posts->the_post();
the_title( '<h2>', '</h2>' );
if ( '' != $a['cat'] ) {
$href = '/category/' . $a['cat'];
} else {
$href = '/blog';
}
echo "<p><a href='$href'>Read More" . ucwords( $a['cat'] ) . '</a></p>';
}
wp_reset_query();
return ob_get_clean();
}
add_shortcode( 'wordpress_recent_post', array($this, 'wordpress_recent_post') );
And then I used this to call the posts from a term called "features" whose id is '183' (suppose)
[wordpress_recent_post cat="183"]
Any help would be really very appreciable.
Thanks!
Adding term slug did it. There should be slug not id, like this:
[wordpress_recent_post cat="features"]
I just updated to Wordpress 3.5, but this crashed a little part of my code:
There is a php file, which loads a specific post with its gallery via AJAX.
The code looks like:
<?php
// Include WordPress
define('WP_USE_THEMES', false);
require('../../../../wp-load.php');
$id = $_POST['id'];
// query post with this identifier
query_posts('meta_key=identifier&meta_value='.$id);
if (have_posts()) :
while (have_posts()) : the_post();
// add content
$content = apply_filters('the_content', get_the_content());
echo '<div class="content-inner">'.$content.'</div>';
endwhile;
endif;
?>
The post contains a [gallery] shortcode. I've build my own Wordpress gallery with this code:
remove_shortcode('gallery');
add_shortcode('gallery', 'parse_gallery_shortcode');
function parse_gallery_shortcode($atts) {
global $post;
extract(shortcode_atts(array(
'orderby' => 'menu_order ASC, ID ASC',
'id' => $post->ID,
'itemtag' => 'dl',
'icontag' => 'dt',
'captiontag' => 'dd',
'columns' => 3,
'size' => 'full',
'link' => 'file'
), $atts));
$args = array(
'post_type' => 'attachment',
'post_parent' => $id,
'numberposts' => -1,
'orderby' => $orderby
);
$images = get_posts($args);
print_r($images);
}
This works with all other galleries on my site, but not with the ajax-loaded ones. And it has worked with Wordpress 3.4.
Are there changes in Wordpress 3.5 that I've overlooked?
I figured it out: If you use a gallery with images, which are already uploaded to the media library, the gallery shortcode looks like [gallery ids=1,2,3], what means, that images are only linked (and not attached) to the gallery, so post_type=attachment doesn't work.
Now i'm using regular expressions to get the image IDs:
$post_content = $post->post_content;
preg_match('/\[gallery.*ids=.(.*).\]/', $post_content, $ids);
$array_id = explode(",", $ids[1]);
It's now possible to pull all the galleries or even a single gallery using the $post->ID and get_post_galleries(). Each gallery will contain the image id list in ids as well as a list of the image urls in src. The gallery object is basically the shortcode arguments so you have access to those as well.
if ( $galleries = get_post_galleries( $post->ID, false ) ) {
$defaults = array (
'orderby' => 'menu_order ASC, ID ASC',
'id' => $post->ID,
'itemtag' => 'dl',
'icontag' => 'dt',
'captiontag' => 'dd',
'columns' => 3,
'size' => 'full',
'link' => 'file',
'ids' => "",
'src' => array (),
);
foreach ( $galleries as $gallery ) {
// defaults
$args = wp_parse_args( $gallery, $defaults );
// image ids
$args[ 'ids' ] = explode( ',', $args[ 'ids' ] );
// image urls
$images = $args[ 'src' ];
}
}
I'm using the plugin "WP Search Suggest" to suggest in the search field.
Now, the plugin works good, but it only suggest and search titles.
I looked in the plugin and found this:
$query_args = apply_filters(
'wpss_search_query_args',
array(
's' => $s,
'post_status' => 'publish',
'post_type' => 'movie',
),
$s
);
$query = new WP_Query( $query_args );
if ( $query->posts ) {
foreach ( $query->posts as $post ) {
$results[] = $post->post_title;
}
$results = apply_filters(
'wpss_search_results',
$results,
$query
);
echo join( $results, "\n" );
}
and I tried to add support to custom field by adding:
'meta_key' => 'somthing',
'meta_value' => '$s'
but I didn't work, and didn't found a way to 'echo' the results because the '$query->posts' array don't hold the meta keys or values...
