First of all, thanks for much for this tutorial as it is describing exactly what I’m looking to do. However, I’m stuck at getting the images to load… was able to add the column, but the images won’t load (placeholders for broken images show instead). I’m thinking I’m very close but just messed up part of the code. Would you be able to point me in the right direct?

My custom taxonomy name is ‘brands’ and the custom field name/slug I’m trying to include in the columns is ‘logo’.

Here is the code I modified off your examples.

// Add to admin_init function
add_filter(“manage_edit-brands_columns”, ‘brand_columns’);

function brand_columns($brand_columns) {
$new_columns = array(
‘cb’ => ”,
‘name’ => __(‘Name’),
‘logo’ => ”,
‘description’ => __(‘Description’),
‘slug’ => __(‘Slug’),
‘posts’ => __(‘Posts’)
);
return $new_columns;
}

// Add to admin_init function
add_filter(“manage_brands_custom_column”, ‘manage_brand_columns’, 10, 3);

function manage_brand_columns($out, $column_name, $brand_id) {
$brand = get_term($brand_id, ‘brands’);
switch ($column_name) {
case ‘logo’:
// get logo url
$data = maybe_unserialize($brand->description);
$out .= “”;
break;

default:
break;
}
return $out;
}

Thanks again!

Do you want to show particular custom posts based on its taxonomy? Probably easiest done by using a plugin which shows the information through a widget. I don’t use many third party plugins, so I don’t know which ones are best, but here are a couple that came up on search-

http://wordpress.org/plugins/flexible-posts-widget/

I’ve tried a couple of breadcrumbs plugins but they simply ignore the custom taxonomy and post type. My theme displays normal tags and categories but ignores the custom ones. And I can’t find any explanation of how to add them in! Aaaaargh!

1. Load custom CSS for wp-admin on user-role base (editor)
2. Remove some columns as per user-role in Woo-Commerce on products page

please reply if you can understood my problem…

I add customization code through my own plugin or through a child theme. For example, the functions.php file of a theme or the main file of a plugin.

Thanks for a very nice tutorial.
What file should we add the code above?

Thanks again,

Hmmm, how about just expanding the Quick Edit menu? Otherwise, I suppose we could make each button into a submit button (no form, just the button) and then hook into the relevant form function. But that seems a bit messy.

Thank you for this great tutorial. I managed to add additional columns to my custom taxonomy. But now I would have to add a column which contains a BUTTON (and not just passive data). Clicking the button should change the value of a custom field for the custom taxonomy.

Maybe it’s easier to show it with an image (“Issue” is the custom taxonomy; I’m trying to do an issue-based publishing system):

My initial solution was to duplicate the default edit taxonomy term form, with hidden fields for the data and a visible submit button. But then I realized that this would create a nested form, since the whole taxonomy term table is wrapped in a form called “posts-filter” (and forms can’t be nested).

If you have any ideas on how to accomplish this custom column with button, it would be highly appreciated!

The Shiba Media Library plugin allows attachment of images to tags. You can look at that and expand it to attach images to categories.
