Title: Editing Post – Loading Field Last modified: April 25, 2020 --- # Editing Post – Loading Field * [hshah](https://wordpress.org/support/users/hshah/) * (@hshah) * [6 years, 1 month ago](https://wordpress.org/support/topic/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 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_post ``` - This reply was modified 6 years, 1 month ago by [hshah](https://wordpress.org/support/users/hshah/). - This reply was modified 6 years, 1 month ago by [hshah](https://wordpress.org/support/users/hshah/). * Thread Starter [hshah](https://wordpress.org/support/users/hshah/) * (@hshah) * [6 years, 1 month ago](https://wordpress.org/support/topic/editing-post-loading-field/#post-12731540) * [@navzme](https://wordpress.org/support/users/navzme/) * I 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.
