Editing Post – Loading Field
-
After selecting images using this Photo Gallery field, I am using the ‘acf/save_post’ action to set each image as an attachment by setting their post_parent field with the post_id.
When I go to edit the post again from the frontend, the Photo Gallery field shows no images. If I do the same from the backend, the images I added before are present.
The other ACF fields are populated when I try and edit the post from the frontend, so I don’t understand why the Photo Gallery field isn’t populated as well, especially since it is when editing the post from the backend.

My issue seems to be the same as this one from over a year ago:

I logged the entire $_POST when saving. My Photo Gallery field is called gallery and its key is field_5ea463d262a41. You can see the 3 test images I added, but I don’t see them when editing the post from the frontend. I also find it odd that the key name isn’t mentioned anywhere.[_acf_screen] => acf_form [_acf_post_id] => 12299 [_acf_validation] => 1 [_acf_nonce] => [_acf_changed] => 0 [acf] => Array ( [field_5e9466f65b151] => blah [field_5e938ffe6a7f7] => sdfsdfsdf [field_5e9f9f307fafe] => no ) [custom_title] => field_5e9466f65b151 [custom_content] => field_5e938ffe6a7f7 [custom_excerpt] => field_5e938ffe6a7f7 [acf-photo-gallery-edit-modal] => Default [acf-photo-gallery-groups] => Array ( [0] => gallery ) [acf-photo-gallery-images_limit] => [gallery] => Array ( [0] => 12295 [1] => 12316 [2] => 12413 ) [acfef_widget_id] => 666d69e [acfef_post_id] => 11475 [acfef_success] => Album Updated [acfef_main_action] => edit_postI managed to fix the images not showing up when editing the post, as well as the edit pencil icon not showing up issue (see the other thread I made earlier).
I had to make changes to your render_field.php, at the lines stated in the errors I posted earlier. I’ve mentioned what I have added, and where I have had to make changes to your code, I have just commented those lines out, and added my version below.
Basically, your $value isn’t a string… it is a nested array of all the images and their metadata (title, caption, url etc.) so the explode function was never going to work.
<?php if( $value ): // New Code $attachment_ids = array(); foreach ($value as $attachments): array_push($attachment_ids, $attachments['id']); endforeach; $acf_photo_gallery_editbox_caption_from_attachment = apply_filters( 'acf_photo_gallery_editbox_caption_from_attachment', $field); //$acf_photo_gallery_attachments = $value; //$acf_photo_gallery_attachments = explode(',', $acf_photo_gallery_attachments); //$args = array( 'post_type' => 'attachment', 'posts_per_page' => -1, 'post__in' => $acf_photo_gallery_attachments ); $args = array( 'post_type' => 'attachment', 'posts_per_page' => -1, 'post__in' => $attachment_ids ); $acf_photo_gallery_attachments = get_posts( $args ); $nonce = wp_create_nonce('acf_photo_gallery_edit_save'); foreach($acf_photo_gallery_attachments as $attachment): $id = $attachment->ID; $url = get_post_meta($id, $field['_name'] . '_url', true); $target = get_post_meta($id, $field['_name'] . '_target', true); $title = $attachment->post_title; if( $acf_photo_gallery_editbox_caption_from_attachment == 1 ){ $caption = wp_get_attachment_caption( $id ); } else { $caption = $attachment->post_content; } acf_photo_gallery_edit($field['_name'], $nonce, $id, $url, $title, $caption, $target, $key, $replace_textarea_editor); endforeach; endif; ?> </div> <ul id="acf-photo-gallery-metabox-list" class="acf-photo-gallery-metabox-list"> <?php if( $value ): //$acf_photo_gallery_attachments = $value; //$acf_photo_gallery_attachments = explode(',', $acf_photo_gallery_attachments); //foreach($acf_photo_gallery_attachments as $image): foreach($attachment_ids as $image): ?>Unfortunately this now seems to have broken the Add Images button, which does nothing when clicked. Not quite sure why because what I changed doesn’t seem to be linked in any way.
Overall though, I am in a better position that I was previously, which is a good thing. I will investigate why the Add Images button no longer works and report back.
