Does anyone have any idea how to add custom meta fields while making categories and fetch them in the loop in WordPress? I was wondering how to do that without hacking the WordPress core, but if I do – it won't become a hindrance to update WordPress in the future.
A plugin I have found that comes close is Wp-Category-Meta, but it doesn't have the ability to add checkboxes as fields in Edit Categories.
This will be very useful as users can make certain categories "featured", and then the code can use that meta value in the loop to style "featured" categories differently.
The problem:
Wordpress does not have a structure nor method to store "meta" values for taxonomies.
UPDATE 2017: WP 4.4+ has "term meta"!
For working with term metas use these:
update_term_meta()
get_term_meta()
delete_term_meta()
add_term_meta()
The Actions below are still valid though! :)
Additional reading: 4.4 Taxonomy Roundup
Solution for WP version <= 4.3.x and COMMON actions
Actions:
create_category and edit_category for category edit
category_add_form_fields and category_edit_form for category form fields
There are more actions than I've presented, but they seem to be deprecated (according to developer.wordpress.org).
The reason I chose the actions that I chose:
- They work on WordPress 4.4.2
- Due to lack of documentation I assumed these are the new ones replacing the deprecated ones...
Functions:
get_option( $option, $default );
update_option( $option, $new_value, $autoload );
update_option has two great abilities:
a) It craetes the option when such option does not exist yet
Unless you need to specify the optional arguments of add_option(),
update_option() is a useful catch-all for both adding and updating
options.
b) $new_value can be an integer, string, array, or object.
You may ask, why to use array/object? ...well, because each option = 1 database row => you probably want to store your category options in one row :)
The CODE
function my_category_form_fields($tag_object){
//output/display extra form fields, e.g. by echo ...
//ADD EXTRA SPECIFIC FIELD TO LATER CHECK IF IT'S CATEGORY SAVE/EDIT!
//(see note at 'edit_category' action...)
if( !empty($tag_object['term_id']) ){
//edit category form specific
//...load existing options with get_option( $option, $default );
} else {
//create category form specific
}
}
function my_category_save(){
//CHECK FOR YOUR EXTRA SPECIFIC FIELD TO CHECK IF IT'S CATEGORY SAVE/EDIT
//(see note at 'edit_category' action...)
//SECURITY CHECK
if( empty($_POST['EXTRA_SPECIFIC_FIELD']) || ! current_user_can('manage_categories') )
return null;
//save your form values using update_option()
//Recommendation:
//Add "category_" prefix and $category_id to your option name!
}
add_action( 'create_category', 'my_category_save', 10, 1 );
//Runs when a category is updated/edited,
//INCLUDING when a post or blogroll link is added/deleted or its categories are updated
//(which causes the count for the category to update)
add_action( 'edit_category', 'my_category_save', 10, 1 );
add_action( 'category_add_form_fields', 'my_category_form_fields', 10, 1 );
add_action( 'category_edit_form', 'my_category_form_fields', 10, 1 );
Create or Edit?
You might wonder whether you are creating or saving a category - this not documented yet (as far as I know), but from testing:
Edit save => $tag_object is object and contains some properties, most notably:
term_id
taxonomy
filter
Create save => $tag_object is just a regular string "category" - I guess this might change in the future...
General taxonomy
There are also actions like these for taxonomies in general - check these actions.
Jaz,
It looks like the plugin you mention in your original question has been updated to include a checkbox field (included in v1.2.3)
I think the Category SEO Meta Tags plugin will help you.
There is an updated and refactured version of this plugin to be found here:
https://wordpress.org/plugins/custom-taxonomy-category-and-term-fields/
Also added a WYSIWYG editor fieldtype.

I want to create a nice readable permalink structure for my custom post type (CPT). My CPT "movie" has the following rewrite-slug movie/movie_name" (all works fine).
Now i want to add arg like this: movie/movie_name/arg and use arg in my template file as a php variable.
But obvious it lead to not-found-page. How can i achieve this target?
edit: i want it in FRIENDLY URL format, it means i dont want to use GET for this.
You may pass it like movie/movie_name?movie_arg=movie_value. It is will be available with $_GET['movie_arg']. Of course your need extra sanitization to handle this data.
To be able to read this in a WordPress way add params to a query_vars filter
function add_movie_arg_to_query_vars( $qvars ) {
$qvars[] = 'movie_arg';
return $qvars;
}
add_filter( 'query_vars', 'add_movie_arg_to_query_vars' );
Note: it should not be same as reserved WordPress query parameters
This way it will be available at your template with get_query_var('movie_arg')
print_r( get_query_var('movie_arg') ) // movie_value

I have added several custom fields to my checkout that only appear when a user is checking out as a guest for the first time. My checkout process requires that the user create an account to complete checkout.
I have added four fields using the woocommerce_form_field method and then I have tried modifying the code provided in the answer here to achieve what I want. However, I have tried several checkouts, creating new accounts to check if the custom field values save into the new users' profile, but it doesn't seem to be working.
Here is one example of a solution I tried which did not work:
function reigel_woocommerce_checkout_update_user_meta( $customer_id) {
if ( ! empty( $_POST['practitioner_license_number'] ) ) {
$pln = sanitize_text_field( $_POST['practitioner-license-number'] );
update_user_meta($customer_id, 'practitioner_license_number', $pln);
}
}
add_action('woocommerce_created_customer', 'reigel_woocommerce_checkout_update_user_meta', 10, 2);
practitioner-license-number is my custom field added using the woocommerce_form_field method. I modified the code at the link above, so that the function runs on woocommerce_created_customer and then in update_user_meta I'm trying to pass the customer ID so that it saves the meta to the user profile that is created.
Would appreciate help trying to solve this. Most of the questions/answers on this subject assume that the user is logged in and already has an account, which is not the case here.
From the code you share, I think the problem lies in incorrectly passing to the $_POST,
perhaps practitioner_license_number vs practitioner-license-number.
You can use the code below to see if your hook works, if the value is written in the database you know that the problem is indeed elsewhere.
It might help to share the code you used for the custom fields too?
function action_woocommerce_created_customer( $customer_id, $new_customer_data, $password_generated ) {
$pln = 'test';
update_user_meta( $customer_id, 'practitioner_license_number', $pln);
}
add_action( 'woocommerce_created_customer', 'action_woocommerce_created_customer', 10, 3 );
I have replaced the wordpress search engine with the WooCommerce product search engine, that is, to include it in the header of my site I use:
get_product_search_form();
instead of :
get_search_form (true);
I would like the product search engine to also search the product categories.
The problem is that I have a category called "Jackets" but the product in its title and in its content uses the word without the "s" so that if I search for the word "jacket" I get many results, but if I search the word "jackets" (with "s") I do not get any, despite that being the name of the category.
I have thought about modifying the query that makes the request so that it adds something of the type: OR category_name LIKE $ search_term, and I tried to use pre_get_posts in functions.php to modify the query, but it doesn't work.
Could someone help me modify that search query for products so that I can also return the products that are of the category whose name matches with the search term.
Thank you very much in advance!
Kind regards,
Raquel
You can look at this link .
simple example:
// hook into wp pre_get_posts
add_action('pre_get_posts', 'jc_woo_search_pre_get_posts');
function jc_woo_search_pre_get_posts($q){
if ( is_search() ) {
add_filter( 'posts_join', 'jc_search_post_join' );
add_filter( 'posts_where', 'jc_search_post_excerpt' );
}
}
I am relatively new to woocommerce development so I am sorry if this question might be too trivial but I need help.
I need in my application a way to make some checks when an admin makes changes to a product in woocommerce.
For example, I want to create a log file of all the changes that occurred on products. Who made them, when and what was the change (price, inventory, description, etc.).
I understand that there are hooks in woocommerce that I can use. Which ones can help me do something like that?
Use post_updated hook for this purpose, place the following code in your functions.php
function product_update_handler( $id, $before_data, $after_data ) {
if( $before_data->post_type == "product" ) {
$current_user = wp_get_current_user();
error_log( $before_data->post_title ." has been updated by ".$current_user->user_login );
}
}
add_action('post_updated', 'product_update_handler', 0, 3);
you have two product objects ( before update, after update ) with the above hook, you can compare both object and log the changes.
I'm trying to sort my custom posts alphabetically without touching any of the core files of the plugin.
I've tried the code below in functions.php and it works. BUT I want it to apply only to a certain custom taxonomy and/or post type.
function set_custom_post_types_order($wp_query) {
// 'orderby' value can be any column name
$wp_query->set('orderby', 'title');
// 'order' value can be ASC or DESC
$wp_query->set('order', 'ASC');
}
add_filter('pre_get_posts', 'set_custom_post_types_order');
I've also tried adding filter through it using "get_post_type" but it doesn't sort posts anymore.
note: it goes through the filter and display test var_dump in each post.
you can add conditions to check if its a taxonomy ( http://codex.wordpress.org/Conditional_Tags#A_Taxonomy_Page_.28and_related.29 ) and/or a specific post type ( http://codex.wordpress.org/Function_Reference/get_post_type, use your query object to get the correct ID ).
