Sortable admin column

tryed the following but did not work:

add_filter( ‘manage_edit-nggallery-manage-gallery_sortable_columns’, ‘thumbnail_post_column’ );
function thumbnail_post_columnn( $columns ) {
$columns[‘thumbnail’] = __(‘Thumbnail’, ‘nggallery’);

return $columns;
}

@sicktb – Looking at your example code neither of the hooks you are trying to use exist in NextGEN Gallery so any callback code used will not be applied. Aside from this, can you provide any additional details on the sort issue you are having?

Thanks!

I’m trying to sort the thumbnail field from a gallerie “Manage Galleries”.
I like it to sort the “broken” image first. When i upload new images to the folder and press scan folder all the thumbnails are broken. This is probably because i don’t use downsampling of the orignal image.

I can fix this by press ‘recover’ one by one. The bulk option is not working for me.

This is the field i like to make sortable:

This are the settings:

Image Options:

Thumbnail Options:

@sicktb – The hooks available for the manage galleries image list (based on the screen snippet) can be found within the following file:
../wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/ngglegacy/admin/manage-images.php

I would recommend trying to make your changes from those filters.

Thanks!

@cais.

I have been looking at the php file but it seems not to be working.

add_filter( 'manage_edit-ngg_manage_images_columns', 'ngg_thumbnail_column' );
function ngg_thumbnail_column( $columns ) {
	$columns['thumbnail'] = 'thumbnail';

	//To make a column 'un-sortable' remove it from the array
    //unset($columns['date']);

return $columns;
}

@sicktb – manage_edit-ngg_manage_images_columns is not one of our hooks (as noted above). If you want to use a specific “hook” to do something it must exist first. In this case, there is no auto-generated hook like it appears you are trying to use, you are only left with the hooks that do exist as referenced in the file above.

Thanks!
