To save the menu order use wp_update_post() with each attachment ID and its new menu position: $thisattachment = array(); $thisattachment[‘ID’] = $thisid; $thisattachment[‘menu_order’] = $new_menu_position; wp_update_post($thisattachment); EDIT – assuming these are already attachments and you’re updating them? Otherwise you have to insert the attachments first with wp_insert_attachment
Link to the image file using wp_get_attachment_link( $id, $size, $permalink, $icon, $text ): $id is the attachment ID, which, if using attachment.php, will simply be $post->ID $size is the image size, e.g. full, large, medium, thumbnail $permalink determines whether a link to the file or post is returned. Use false (which is the default) to … Read more
Check out this search and replace plugin. The benefit of using an absolute URL is that you can easily find and replace it, either with the plugin linked above or an SQL statement or even using some built in WordPress API’s. So I wouldn’t do anything differently the next time. I used the search and … Read more
wp_get_attachment_image() does not pass output through any filters. You should apply changes to output of this function or use custom function for output.
After some additional searching I was able to come across a function to generate the attachment ID here: http://pippinsplugins.com/retrieve-attachment-id-from-image-url/: // retrieves the attachment ID from the file URL function pippin_get_image_id($image_url) { global $wpdb; $prefix = $wpdb->prefix; $attachment = $wpdb->get_col($wpdb->prepare(“SELECT ID FROM ” . $prefix . “posts” . ” WHERE guid='” . $image_url . “‘;”)); return … Read more
This completely depends on how your gallery shortcode looks like. If you replaced it with something custom, then you’ll have to take a look at the plugin (or the theme). The default gallery shortcode gets it from a query: $query_args = array( ‘post_status’ => ‘inherit’ ,’post_type’ => ‘attachment’ ,’post_mime_type’ => ‘image’ ,’order’ => $order ,’orderby’ … Read more
A very simple workaround is: don’t attach the images to the post. Upload the images directly in the Media Library: http://example.com/wp-admin/media-new.php, go to the post and insert selecting it from “All Media”, it won’t be shown in the “attachments” list.
There is no complete solution possible. And that is not new. Any image can be a part of a gallery in a post that is not that image’s parent. So the post parent is not a useful parameter. The new interface makes such galleries easier to create, but they were possible in earlier versions too. … Read more
The solution to this is that you have to search for posts first, and afterwards to images to the post. In my code I included a parameter exclude to ensure the current post is not delivered again. Please keep in mind that if a post has no Image, none will be shown. Also, I did … Read more
I think that importing attachments separately (which is not possible with native export) is precisely cause for your issue. Importer plugin has following code: if ( $post_parent ) { // if we already know the parent, map it to the new local ID if ( isset( $this->processed_posts[$post_parent] ) ) { $post_parent = $this->processed_posts[$post_parent]; // otherwise … Read more
