[Plugin: File Un-Attach] not sure that multiple attachments is working properly

I didn’t test this plugin with custom post types, I will test it and let you know but probably this is going to be an update for next release

Thanks for looking Hax! ??

Hello Hax,
Any news on the “multiple” issue?
We see “multiple” but canNOT see the posts/pages the file is attached to.
Any updates coming up?
Thank you for your time and work ??

hi,

i also was looking for a way to attach a file to multiple posts and posts types. and for me also it wasn’t possible to retrieve these files in the posts where the library was saying the file was attached to… so i ended up to create a function that seems to work ?? here it is :

<?php

// Stop direct access of the file

function fun_get_attachments( $args = array() ) {
	global $post;

	$defaults = array(
		'post_parent'    => 0,
		'post_type'      => 'attachment',
		'post_mime_type' => 'image',
		'orderby'        => 'menu_order',
		'order'          => 'ASC',
		'numberposts'    => -1,
		'meta_key'       => '',
		'meta_value'     => '',
	);

	$args = wp_parse_args( $args, $defaults );

	if ( !$args['post_parent'] )
		$args['post_parent'] = $post->ID;

	if ( !$args['post_parent'] )
		return array();

	// usual way to get pdf attached to this post
	$attachments = get_children( $args );

	// FileUnattach way to get attachments
	if ( !$attachments && class_exists( 'FileUnattach' ) ) {
		$args['post_parent'] = '';
		$args['meta_key']    = '_fun-parent';
		$args['meta_value']  = $post_parent;

		$attachments = get_posts( $args );
	}

	if ( !$attachments ) {
		return array();
	}

	return $attachments;
}
?>

make a plugin/file-unattach-helper/file-unattach-helper.php file with this content the use something like this to get pdf attachments for exemple :

$attachments = fun_get_attachments( array( 'post_mime_type' => 'application/pdf' ) );

i hope this could help.

Séb.

arg ! there is a typo and i cannot edit the post no more !

you have to replace $post_parent with $args['post_parent']

sorry…

after more tests, i see that the function does not work wery well… so here is a better one :
