[Resolved] Question about listing post attachments

Hi there,

We had a question about listing post attachments. Our objective is to display a list of PDFs that have been uploaded and inserted into the body of a post. (The list of PDFs will appear below the body in a separate section.)

In the Views interface, we don't see "attachment" as a post type. From our research, we see that we can write custom PHP and use get_posts() for a post_type="attachment" and where the post_parent is the current post ID. Is this possible to do from Toolset's visual interface via Views, or do we need to rely on PHP?

The code we're referencing is in this StackOverflow post: https://stackoverflow.com/questions/42917812/how-to-get-all-attachments-for-a-wordpress-post.

Thank you!

Saul

Hi Saul,

Welcome to Toolset support. There is no GUI feature to add attachments to a post in Toolset.

You can use Toolset to add a custom PHP code to achieve this:

https://toolset.com/documentation/programmer-reference/adding-custom-code/using-toolset-to-add-custom-code

The PHP should be something like this:

function get_post_pdfs() {
    global $post;
    $args = array(
        'post_type'   => 'attachment',
        'post_mime_type' => 'application/pdf',
        'post_parent' => $post->ID,
        'posts_per_page' => -1
    );
    $attachments = get_posts($args);

    if ($attachments) {
        $output = '<ul>';
        foreach ($attachments as $attachment) {
            $url = wp_get_attachment_url($attachment->ID);
            $title = get_the_title($attachment->ID);
            $output .= "<li><a href='$url' target='_blank'>$title</a></li>";
        }
        $output .= '</ul>';
        return $output;
    }
    return '<p>No PDFs found.</p>';
}
add_shortcode('post_pdfs', 'get_post_pdfs');

Then, add this shortcode to the post content or template:

[post_pdfs]

The code is not tested, but can give a good starting point for you.

Thanks.

Christopher,

This is fantastic. Thanks so much.

I might request, as a feature, that attachments be incorporated into Views. They're a native WordPress post type, and it would be great to be able to control the display of them via Toolset.

Thanks again!

Saul
