WordPress allows you to attach a media file association to an article, but the association cannot be modified by default. This tutorial will add an option to modify the attachment of a media file association.

Add the following code to the functions.php file of the current theme:

add_filter( "manage_upload_columns" , 'upload_columns');
add_action( "manage_media_custom_column" , 'media_custom_columns', 0, 2);
function upload_columns( $columns ) {
unset( $columns ['parent']);
$columns ['better_parent'] = "Parent" ;
return $columns ;
}
function media_custom_columns( $column_name , $id ) {
$post = get_post( $id );
if ( $column_name != 'better_parent')
return ;
if ( $post ->post_parent > 0 ) {
if ( get_post( $post ->post_parent) ) {
$title =_draft_or_post_title( $post ->post_parent);
}
?>
<strong><a href= "<?php echo get_edit_post_link( $post->post_parent ); ?> " ><? php echo $title ?></ a></strong>, <? php echo get_the_time(__('Y/m/d')); ?>
<br />
<a class = "hide-if-no-js" onclick= "findPosts.open('media[]','<?php echo $post->ID ?>'); return false; " href= "#the-list" ><? php _e('Re-Attach'); ?></ a>
<? php
} else {
?>
<? php _e('(Unattached)'); ?>< br />
<a class = "hide-if-no-js" onclick= "findPosts.open('media[]','<?php echo $post->ID ?>'); return false; " href= "#the-list" ><? php _e('Attach'); ?></ a>
<? php
}
}
