Hi!

I have made a custom multi-select field, using <optgroup> to organize the continents:

{optgroup}Africa|Uganda,Zambia,Zimbabwe{/optgroup}, {optgroup}Asia|Afghanistan,Bahrain,Bangladesh{/optgroup}

This solves the problem on the front-end using the suggested Advanced Search addon. (Because customers most likely will not have to select continents)

I suppose the name of the continents act as group labels, while the countries are group values.

So to the big question: is there a way for businesses, using admin-backend and the “add/edit listing” page, to be able to select ALL the different Countries where they will ship their goods to – using the multi-select input field?
(Ex. If the wanna ship to Africa, they don’t have to choose all African countries – Only click Africa and all the other ones are selected)

I know Cntl + Click is an option, but this not possible from mobile (?) and is not very intuitive

Hello!

Thanks for your answer and example code! We actually had a similar discussion regarding the exact same issue three months ago.

My end goal is to use GeoDirectory to create a subscription listing site. On this site businesses can list their deals, while customers can browse through the different businesses and deals using various sorting filters.

A main sorting option should be “Ship To”, where customers should be able to select all businesses that will ship to a particular customers Country.

On the admin-backend and the “add/edit listing” page, businesses should be able to select ALL the different Countries where they will ship their goods to – using the multi-select input field.

(I cannot see how the “Location Manager” could solve this issue, please correct me if I am wrong!)

Because of the potential high number of Countries, a business owner should be able to only select Continents (ex. Africa) if they ship goods to ALL Countries within this Continent. If however, one or more of the Countries in a Continent are un-checked or not selected, the continent itself will be un-checked/not selected.

To make this possible I have created a CPT and been trying to use the CPT category like this (Continents = Parents, Countries = children):

* Africa
 - Uganda
 - Zambia
 - Zimbabwe
* Asia
 - Afghanistan
 - Bahrain
 - Bangladesh
 - Bhutan

By implementing the code below, I seem to be able to achieve this Continent-Country behavior in the core WordPress taxonomy when selecting Continents or de-selecting Countries [Se Image]:

function array_diff_once($a1, $a2){
 for each($a2 as $val){
 if(false !== ($pos = array_search($val, $a1))){
 unset($a1[$pos]);
 }
 }
 
 return array_values($a1);
}

add_action('set_object_terms', 'toggle_child_terms', 10, 6);
function toggle_child_terms(object_id, terms, $tt_ids, taxonomy, append, $old_tt_ids){
 // Abort if this is an autosave/backup
 if(defined('DOING_AUTOSAVE') && DOING_AUTOSAVE)
 return;

 // Abort if no ids are set from before or now
 if(empty($tt_ids) && empty($old_tt_ids))
 return;

 // Only do things if this post is published (front facing)
 $post_status = get_post_status(object_id);
 if($post_status != 'publish')
 return;

 // What terms where ADDED, and which were REMOVED?
    $added_terms = array_diff_once($tt_ids, $old_tt_ids);
 removed_terms = array_diff_once($old_tt_ids, $tt_ids);

 // Any terms ADDED this time?
    If(!empty($added_terms)){
 for each($added_terms as $added_term){
 // Do any of these added terms have children?
            If($added_child_terms = get_term_children($added_term, taxonomy) ){
 // Append those children
 wp_set_object_terms(object_id, $added_child_terms, taxonomy, true);
 }
 }
 }

 // Any terms REMOVED?
    If(!empty(removed_terms)){
 for each(removed_terms as removed_term){
 // Do any of the removed terms have children?
            If(removed_child_terms = get_term_children(removed_term, taxonomy) ){
 // Remove them all
 wp_remove_object_terms(object_id, removed_child_terms, taxonomy, true);
 }
 }
 }
}

But these changes are NOT visible inside the CPT subscription post [See img]

When looking at the wp_geodir_gd_subscription_detail table in the database, there is a field called post_category that are populated with values from the category input field (Ship To) – See image above. When looking more closely, I can tell that the values in the ‘post_category’ field are NOT the same as:

categories = wp_get_post_terms($gd_post['post_ID'], 'gd_subscriptioncategory', array('fields' => 'ids') );

For making ‘post_category’ match the core WordPress category settings (Continent – country) that are generated through the custom toggle_child_terms function (above), I have been trying to somehow copy the content from

categories = wp_get_post_terms($gd_post['post_ID'], 'gd_subscriptioncategory', array('fields' => 'ids') );

to ‘post_category’ in different ways, unfortunately without success.

add_filter('geodir_save_post_temp_data','my_post_filter',15,3);
function my_post_filter($gd_post, $post, update){

 categories = wp_get_post_terms($gd_post['post_ID'], 'gd_subscriptioncategory', array('fields' => 'ids') );

 $gd_post['post_category'] = categories;
 custom_logs($gd_post['post_category']);
 custom_logs($gd_post);

 return $gd_post;
}

For this last try, using your example code, I seem to be able to copy the categories at first, custom_logs output:
{---"post_category":[626,627,628,629,630,631,632,633,634,625,635,636,637],"---}

,but then when the page is refreshed only the selected in Continent was checked and not the Countries – the same for the post_category field in the database.

It seems like “something” happens after the geodir_save_post_temp_data hook that reverts the post_category field back to pre-my_post_filter categories.

I hope this explanation made sense, and that you might have an advice for me that could lead to a solution for this issue.

Thank you!

Thanks for your answer, not entirely sure how to customize this geodir_save_post_temp_data filter to update the post_category field?

Thank you for the suggestion, I did try the WP Job Manager Field Editor add-on.
It has no option for setting parent category as <optgroup>

Her is the URL
