The filter "woocommerce_product_get_price" to show a custom price works but casually I have discovered that this filter is triggered five times in single product page and six times in the archive product page. This I have checked including a var_damp in the following way:
add_filter('woocommerce_product_get_price', 'get_ws_price', 10, 2);
function get_ws_price($price, $product){
var_dump('HI!');
$price = 99.99;
return $price;
}
This is a problem for me, I use this filter to perform complex code and is repeating them many times.
What am I doing wrong?
Is there another way to modify the price of the product with another hook?
WooCommerce also has this problem which it solves by caching. It uses the WordPress get_transient() and set_transient() to save a version in the WordPress database. This allows the calculation to be used over multiple requests. Further, the calculation is saved in a global object so that within a single request the calculation can be retrieved from an in memory object.
WC_Product_Variable_Data_Store_CPT::read_price_data() in file '...\wp-content\plugins\woocommerce\includes\data-stores\class-wc-product-variable-data-store-cpt.php' is a good example of this technique.
You could choose to not use the filter and write your own function to replace get_price_html(). With the new function you can overwrite your WooCommerce templates such as the single product page woocommerce\templates\single-product\price.php and replace any calls to this function with your own custom function. This way it will only be called once.

I have function that update post content automatically based from custom field like this:
function update_content(){
$mycustomfield = get_post_meta( get_the_ID(), 'customfield', true);
$post = array();
$post['ID'] = get_the_ID();
$post['post_content' ] = $mycustomfield ;
$post['post_title' ] = $mycustomfield ;
// Update the post into the database
wp_update_post( $post );
We update only custom field to make content. For now, we launch this function manually on save_post hook, but the articles are so many and we need now a cron to automate this function: process 4 posts every hour until all posts are completed, then start over.
How to make this, thank you
WordPress actually has a built-in psuedo cron system called WP Cron. It doesn't function exactly like a proper server cron, but can perform a similar function in many cases. You can find documentation on it here:
https://developer.wordpress.org/plugins/cron/#:~:text=WP%2DCron%20is%20how%20WordPress,post%2C%20utilize%20WP%2DCron.&text=WP%2DCron%20works%20by%20checking,what%20needs%20to%20be%20run.
However thinking about your use case and looking at your function above, I'm wondering what the purpose of your cron is? It looks from that function like all you're doing is taking some content already in your database and putting it somewhere else. Why? Why not simply display your custom field in the correct spot? Or better yet, use the fields as intended?
Even if that is necessary - maybe I don't understand fully from the example above - I think your initial inclination to run this on save_post is much more correct. Unless there's some information external to your site that's changing, the only time these values will change is when you save the post. So what is the purpose of running it on a schedule?
I have a WooCommerce set up, whereby all orders are added manually.
When I add a (pending) order, the WooCommerce order status hook registers the sale (for reporting).
I wish the switch this process to the hook called only when the order is (again manually) set to 'complete'.
There are a couple plugins ( eg. https://docs.woocommerce.com/document/woocommerce-order-status-control/ / https://wordpress.org/plugins/advanced-reporting-for-woocommerce/ etc ), but these are either overkill or simply don't provide this functionality..
I've also found a couple related posts, essentially describing overriding the woocommerce hooks to this end ( Getting order data after successful checkout hook etc, but unfortunately whilst the solutions correspond ( ie adapting the correct hooks - the context differs ).
I'm reluctant to prevent functionality in these hooks when attempting to overwrite/reorder the actions so any pointers which hooks I can use to achieve this would be really helpful.
Many thanks!
maybe you can try to use the ... filter, something like (untested):
add_filter( 'woocommerce_reports_order_statuses', 'fc_order_status_reports', 20, 1 );
function fc_order_status_reports( $statuses ) {
$statuses = array('completed');
return $statuses;
}
The code snippet is to add to your active theme's functions.php file.
Let me know if it does the job ;)
Apologies if this appears simple to some, but I have scaled high and low and I'm not finding a solution here to my problem, which is:
I have a website set up with Wordpress in which posts can fall under one of three categories: reviews, views, news - the slugs associated with each of these category names are the same.
Currently, calling up the web page of any individual post classified under any of these categories will see it rendered by the file single.php.
However, I want to make a slight adaption to the rendering of the post when it falls within the 'reviews' category. I have copied and renamed the original single.php file to single-post-reviews.php (no custom posts here, I will just confirm and I would like, if possible, to avoid child-theming here - not good practice, I know), but I am not seeing the new rendering from my new file.
I've also tried renaming to single-reviews.php which hasn't worked either - so could someone tell me what exactly I'm missing here?
Thanks,
WordPress Template Hierarchy for Single Posts doesn't factor in the current post category (likely due to the fact you can have multiple categories). Due to this, you have 2 viable options to your problem.
1) You can modify single.php to check for the post category, and if it's categorized under reviews, do something. This makes sense if you're just adding a small amount of markup in one or two places, or even hiding a few lines conditionally.
2) You can override the page template that's loaded based on the post's category using the single_template filter. Because I don't know exactly what you're doing, I'm going to elaborate more on this method. Take the following function:
add_filter( 'single_template', 'so51913799_review_template' );
function so51913799_review_template( $single_template ){
global $post;
if( has_category( 'reviews' ) ){
$single_template = get_stylesheet_directory() . '/single-post-reviews.php';
}
return $single_template;
}
If you put it in your functions.php file, it will make use of the has_category() function (I prefer this to in_category() since in_category just returns has_category anyways) and if it matches, it will update the $single_template variable to single-post-reviews.php. This assumes that the file is inside your /wp-content/themes/ACTIVE-THEME/ directory.
In BuddyPress, it shows 20 members per members directory page. I want to list 24 members per page with a pagination and sorting must work perfectly. I tried:
bp_has_members(bp_ajax_querystring('members').'per_page=24'))
It works but pagination and sorting are not working correctly.
For those like me wondering how to do this nowadays and ending here after searching with their fav engine, the proper way is to use a filter in bp-custom.php or the functions.php of your theme.
Cf. https://codex.buddypress.org/developer/using-bp_parse_args-to-filter-buddypress-template-loops/
For the member loop it would be something like :
function my_bp_members_per_page( $retval ) {
$retval['per_page'] = 24;
return $retval;
}
add_filter( 'bp_after_has_members_parse_args', 'my_bp_members_per_page' );
Bonus : this will still work if you use cache like WP Rocket.
Former method doesn't work with cache and logged in user.
You need an '&' for each additional argument.
Try:
bp_has_members(bp_ajax_querystring('members').'&per_page=24'))
To modify this file, you make a copy of it and put it into your child-theme
/your-child-theme/buddypress/members/members-loop.php
Is there a way of having categories available right after installing a theme.
For instance, if a theme post content to a loop which retrieves posts with the category "Tagline". Is there a way of having the category "Tagline" by default (in the theme)?
(So the end user wouldn't have to create it himself/herself)
Try using wp_insert_category(); -- see: http://codex.wordpress.org/Function_Reference/wp_insert_category
You'd probably have to write an init function in functions.php that runs the first time the theme is activated and calls the above function. You'll want to write some error handling that prevents it from being run multiple times, however.
