How To Include Only Chosen Posts (by id) - Wordpress Shortcode - php

Question

This shortcode shows the last X (sorting from the newest to the oldest) posts on my home page. I want to choose which ones I'd like to show by ID. How to do it?
I have a shortcode which looks like this
This is what input:
if(!empty($blog)){
echo do_shortcode('[blog item_number=4]');
}
This is a code of this shortcode.
function beau_blog($atts, $content = null, $code = '')
{
global $imgsize;
extract(shortcode_atts(array(
'post_not_in' => '',
'item_number' => '4',
), $atts));
$loop = new WP_Query('&posts_per_page=' . $item_number);
?>

Answer 1

change you function beau_blog() as below only the initial few lines other is same as it is
function beau_blog($atts, $content = null, $code = '')
{
global $imgsize;
extract(shortcode_atts(array(
'post_not_in' => '',
'post_in' => '', //you cannoot use post__not_in and post__in in same query so you have to use either one of that. I've modified it to give priority to post_in so if that argument is empty then only the post_not_in ids are used to exclude those posts.
'item_number' => '4',
), $atts));
if(empty($post_in)){
$loop = new WP_Query('&posts_per_page=' . $item_number.'&post__not_in='.$post_not_in);
}
else{
$loop = new WP_Query('&posts_per_page=' . $item_number.'&post__in='.$post_in);
}
?>
.....
Now when you want to show posts of ids 1,2 and 3 only do it as below
echo do_shortcode('[blog item_number=4&post_in=array(1,2,3)]');

Answer 2

please try below code - this is simple sample
function show_posts_by_id( $atts, $content = null, $code ) {
$item_number = 4;
$post_ids = null;
extract(
shortcode_atts(
array(
'post_ids' => '',
'item_number' => 4,
),
$atts
),
EXTR_IF_EXISTS
);
$posts = get_posts(
array(
'post_type' => 'page',
'post__in' => explode( ',', $post_ids ),
'posts_per_page' => (int)$item_number,
'offset' => 0,
'orderby' => 'post_date',
'order' => 'DESC',
)
);
// do what you need
}
add_shortcode( 'show_posts_by_id', 'show_posts_by_id' );
Use shortcode like this: [show_posts_by_id post_ids=12,15,2176 item_number=4]
