Two e-commerce in two different folders of the same domain
I need to create two e-commerce with woocommerce, one in the main directory of my site in Italian and English for online sales in Europe, and one in a subfolder or subdirectory exclusive for Switzerland in CHF with differentiated prices. I would like to know if you have to install wordpress also in the subfolder, so a wordpress installation for each woocommerce plug or can you manage the two online shops even with a single installation? And in any case, what do you recommend for a better performance?
Thanks in advance. | > I would like to know if you have to install wordpress also in the subfolder, so a wordpress installation for each woocommerce plug or can you manage the two online shops even with a single installation?
Both options work, either 2 installations of WordPress with WooCommerce installed, or a single installation of WordPress set up as a multisite.
Neither will give a performance benefit over the other, but the multisite install will be simpler to maintain | stackexchange-wordpress | {

How to dynamically set a background image with the customizer without putting the css as an inline-style
Here is what I am using currently,
`<div class="home-header" style="background-image:url('<?php echo get_theme_mod( 'home-header-img' ); ?>'); height: 500px; width: 100%; display: flex; justify-content: center; align-items: center; background-repeat: no-repeat">`
I have the background-image being set by the customizer and it's working great however I am unable to have inline styles due to the ThemeForest theme standards. What should I be doing here? or is there a better way to go out this? thanks | I would recommend changing it to this:
<div class="home-header" style="background-image:url('<?php echo get_theme_mod( 'home-header-img' ); ?>')">
and adding this to style.css or an other stylesheet:
.home-header {
height: 500px;
width: 100%;
display: flex;
justify-content: center;
align-items: center;
background-repeat: no-repeat;
}
In general, inline styles are not allowed, but Themeforest makes an exception for background-images. So by moving the remaining code in a CSS-file and only leaving the image, you're fully compliant with Themeforest's requirements. The exception for images is mentioned in this article.
Let me know how it goes!
PS: If you want to add the code using `wp_add_inline_styles()`, but don't know how it works, I can also give an example of that. | stackexchange-wordpress | {

How can I add more "filters" to my products? (Categories, attributes, etc.)
I want to make a shop that sells car parts. In order to do so I need additional categories such as make, model, year and so on. The reason why I don't want to put everything in the "categories" section is that I will want to implement a "search by car model" feature, like this: ![Car parameters](
My worry is that if I put all the information in the "categories" section of the product, then the user will not only see BWM, Audi, etc. but will also see other names of the categories such as "Make" and "Year" in the dropdown menu.
How should I go about solving this problem? For refference, this is my 1st time using wordpress and my experience is not that vast (2nd year of CS) | I presume here that you're using a shopping cart system such as WooCommerce?? If that's the case, you could create new taxonomy terms for the products cut that WooCommerce creates using something like the below:
// Create custom taxonomy for parts CPT
add_action( 'init', 'create_vehmake_taxonomy' );
function create_vehmake_taxonomy() {
register_taxonomy(
'veh-make',
'product', // CPT slug here
array(
'label' => __( 'Vehicle Make' ),
'rewrite' => array( 'slug' => 'make' ), // Tax Term Slug (URL)
'hierarchical' => true,
)
);
}
You could in theory create multiple of these to cater for your needs.
However, for ease of use, I'd probably be more inclined to use the Advanced Custom Fields plugin to create new meta fields on your product CPT that you can then use as select fields or text inputs to populate the data you need on a per-product basis. | stackexchange-wordpress | {

WP Multisite - domain mapping to domain.com and separate site to domain.com/help
I'm considering setting up a WP multisite network. It would seem to fit my situation perfectly. There's one thing I still need to find out about domain mapping.
Say I have the multisite installed on the following example root domain: `multisiteroot.com`. Each subsite is installed on a subdomain. Further, I also registered a domain: `businessdomain.com`.
I now want to have two separate WP websites and map them to respectively `businessdomain.com` and `businessdomain.com/help` (or sth like that).
Is it possible to install WP Multisite on a root domain with subsites on subdomains, and map two of those subsites to `businessdomain.com` and `businessdomain.com/help`? | Yes, this is possible (see < For sub-domains you'll need to confirm that your DNS has a wildcard entry for your domain. So, based on your root domain, this would work for: mysub1.multisiteroot.com, mysub2.multisiteroot.com, etc.
If you wanted to us different domain names for subsites, then you'd need to have those domain names point to your IP, and then, in the Network Admin "Edit Site" page for your new subsite (Network Admin path: All Sites > Edit (site site to be modified):
1. Info tab - Change "Site Address (URL)" to the URL to name of your subsite (e.g. " then click "Save Changes";
2. "Settings" tab - change the "Siteurl" and "Home" values to the URL for your subsite, then click "Save Changes".
As for "businessdomain.com/help", this is a subfolder. I recommend using a subdomin "help.businessdomain.com", using the website I listed above and mu notes.
I hope I didn't miss a step, or two.

How to deal with logo color on dark mode?
I'm trying to add a dark mode on my website via prefers-color-scheme webkit. However, my logo is all black, while my header is white. On dark mode it should be the other way around. My logo is in PNG and I thought it wouldn't be a bad idea to somehow upload two logos with different selectors and hide one via CSS on light mode, and the other one on dark mode. My question is: is there any way to do it?
If no, does anyone have any other ideas how could I achieve what I need?
EDIT:
I'm trying to do exactly the same thing as this guy:
However, his logo is a simple text so he can easily change its color via CSS. Mine is in PNG and I'm not able to do this. | 1. Apply `filter: invert(1)` in dark mode if your logo is simple enough (in shades of grey).
2. Overlay your dark mode logo on top of your normal logo and change the opacity.
This is what we do. Our logo consists of two lines of text, one of them is black and the other is colored. We have the same logo in two containers overlaid one above the other (`position: absolute`), but one container is half the height of the logo to only cover the first line of text and it has the `invert` filter applied. When switching to dark mode (with a cool transition), the inverted logo (one white line of text) is revealed.
3. Use SVG. | stackexchange-wordpress | {

Loading and Referencing Images
I'm slowly writing a page to manage an asset database; effectively, writing a very basic plugin. I want to import photos and found some excellent examples of how to do this and, made it work! My problem then was to display the images in the page. Although I know the uploaded image filename, there seems to be no way to use it. The image will be put into the current 'date' folder and could well be renamed on the way. I've ended up querying the last post ID just before I import the image and adding 1 to it to reference the image. With the post ID I can then use `wp_get_attachment_image_src` to get a url for the (resized) image:
wp_get_attachment_image_src( $result->PostNum, 'medium_large' );
It works but it is very clunky. Is there a better way of doing this? | Could be the piece you're missing here is that after you upload photos if you want to get to that item again to do anything with it, including get its URL, the thing you need to keep is not the filename but the ID that you get back.
You can then call e.g. `wp_get_attachment_image_src` directly with that ID to get the URL for that image.
If you don't have a way to store that ID in a useful place and recall it when you need it, you may need to resort to some other way to figure it out, such as what you're doing.

Woocommerce, finding the ordinal number of a purchase for a certain product
we are developing a complex Woocommerce website and an app which uses V3 API.
Being sold products very valuable, we need to know the ordinal number of a purchase for each product. For example, we'd like to know that Alice was the third to buy that product and Bob the fifth and so on. What I can think of is to get the total sales through Woocommerce API for that product, then loop every order containing that product and order them by date. The problem is that this way is very time and resources consuming, especially having to loop through all the orders. Does anybody know a better approach. I don't ask for the code, but I'd be glad if someone could have a brilliant approach to share.
Thanks! Fabio | Assuming you are not allowed guest checkout what you can try is
* add a custom field to your WooCommerce products in which you would save the history of purchases as an array like `[<user_id_1>, <user_id_2>, ...]`;
* write a custom function and use a `woocommerce_order_status_completed` hook to update this field according to products within the order (see this question for information on how to get user ID from the WooCommerce order);
* write a function which will do a loop through all already placed orders and initialize that field value for each of your products.
This can be done as a plugin where initialization of this custom field will occur during plugin activation. And with the same plugin you could register an additional REST API endpoint. | stackexchange-wordpress | {

Permalinks by page/post name returning 404

Shorter admin url for options page
Is it possible to create a short admin url for options page?
The default admin url is:
domain.com/wp-admin/admin.php?page=options-page-slug
And i want it to be: domain/wp-admin/options-page-slug | You mean, `wp-admin/ _admin.php_?page=options-page-slug`?
But yes, you can use the rewrite API:
add_action( 'init', function () {
// The following adds the rule into the database.
add_rewrite_rule(
'wp-admin/options-page-slug(/|$)',
'wp-admin/admin.php?page=options-page-slug',
'top'
);

Or alternatively, just add this before the WordPress rules in your `.htaccess` file:

Theme support title tag - how to replace the default WP separator (with a filter)?
I'm developing a theme for Themeforest and one of their requirements is about the tag. Themeforest states their requirement as follows:
_The theme must let WordPress add and manage the title. This is done by adding`add_theme_support( 'title-tag' );` to functions.php instead of using `wp_title()` in the document head._
The current output is on the home page: '`Site title - Site tagline`'. On other pages it is '`Post or page title - Site tagline`'.
The separator is '-'. Can anyone give an example of a filter for this, so that I can change the separator to '|' or a character of my choice?
Many thanks in advance! | You use the document_title_separator filter.
So in your case:
<?php
function theme_prefix_filter_document_title_separator() {
return '|';

Conditional to determine if search.php page is the current template
I have a specific CSS-file for my search results, so the search.php template. I want a PHP if-condition to determine if the current template is the search.php template, so that I can load that CSS-file with `wp_enqueue`. The condition should work in the functions.php file.
I'm not entirely sure if I can use `is_search()` for this. Can anyone confirm I can use `is_search()` and, if that's not the case, provide an alternative?
Many thanks in advance! | WordPress conditional functions will not tell you which template _file_ is used. They tell you what the current request is for. Which file is loaded for that type of request is determined by the template hierarchy.
So, `is_search()` will tell you if search.php is being used if the current request is a search, and the current theme includes a search.php. If the theme does not include search.php, `is_search()` will still return `true` if index.php is used, as per the template hierarchy.
That's the long way of saying that if your theme has search.php, then yes, use `is_search()`. | stackexchange-wordpress | {

Redirect Single Post CPT (Custom Post Type) to a specific URL

When clicking on the grid item, the **single** post is shown for example: `domain.com/resources/resource-title`
I'd like to remove the **single** post from the domain and redirect on click to `materials.domain.com/resource-title`. I already have this page on the `materials`subdomain).
How can I achieve that? | Sometimes this would be achievable with `add_rewrite_url` but it looks like in this case it's not as you need to redirect to a different domain.
In this case you need .htaccess or nginx rules to do this, so you need to add something like this to your nginx config **for domain.com only** , in order to rewrite those URLs:
`rewrite ^/resources/(.+) permanent;`
You'll likely need to restart nginx after you add this to the config file.

Randomizing wp_tag_cloud() in child theme
I'm trying to write a wordpress function code in my child theme that randomizes the words in the word cloud where previously it was alphabetized.
The code Im using is below, which doesn't work.
//
add_filter('wp_tag_cloud_args', 'my_wp_tag_cloud_args_filter');
function my_wp_nav_menu_args_filter($args) {
$args['order'] = 'RAND';
// do something
return $args;
}
//
I'm able to update the wp_tag_cloud()'s default ('Order' = 'RAND') args in wp-includes/category-template.php but I know that any changes will get replaced. The change work when in that file.
How can I move those set of changes to my wordpress child theme? | Try the `tag_cloud_sort` hook:
add_filter( 'tag_cloud_sort', 'shuffle_tags', 10, 2 );
function shuffle_tags( $tags, $args ) {

Assign custom class to post content images
Is possible to assign a default class to the images that are part of a post content?

How to assign a specific service to a specific provider based on location

customizer not working when ever i activate ssl

Console Screen shot:
![enter image description here]( | If you're using Cloudflare's flexible SSL then you will run in to issues with WordPress. From my basic understanding, this is because Cloudflare's flexible SSL doesn't offer end-to-end encryption, it essentially encrypts items between the client and Cloudflare, but not from Cloudflare to your server.

How to customize the critical error message?
How to customize the critical error message saying:
> There has been a critical error on your website.
>
> Learn more about debugging in WordPress.
Instead of using CSS to hide the message it would be interesting to be able to point the link to another source than the community article. | You can use the `wp_php_error_message` filter to customise this message:
add_filter(
'wp_php_error_message',
function( $message, $error ) {
return 'My custom message.';

2
);
I haven't tested to be sure, but I would assume that if the critical error that causes this message happens to be in the code of same theme or plugin that this filter is used in, or a theme or plugin loaded before it, then this filter would likely not apply.
If you want to change this message independently of your theme and plugins, this might be a good use case for a Must Use Plugin. | stackexchange-wordpress | {

Instead, you would create a theme file such as "page-about.php" and create its content in wp-admin as a Page with the slug "about," and WordPress will process that Editor content within the PHP file to create the final visible page. If you have pretty permalinks enabled you will want to link to "/about/" instead of the theme file, but because you have named the PHP file "page-about," WP will apply it to a Page with the slug "about." | stackexchange-wordpress | {

Can anyone point me in the right direction? | `get_next_posts_link()` and `get_previous_posts_link()` are for linking between pages of a paginated post archive.
For navigation between individual posts you want `get_next_post_link()` and `get_previous_post_link()`. Note the singular "post".

As shown in the docs `array_push()` acts on the array and takes multiple parameters which get added as array values.

$tabs = $tabs + arrary(
'111' => 'aaa',
'222' => 'bbb'
);
return $tabs;
}, 10);

Filter wp_redirect() to stop redirect under certain condition

I would like to stop the `wp_redirect()` function from actually doing the redirect if the debug tool contains a message that it wants to display.

I have seen the `wp_redirect` filter allows me to filter the redirect location.
I could say "go back to the same place" but that would be a new http request and the logs would be already lost. | As you can see from the source code, `wp_redirect` always ends in a PHP header request, **except** if the location is empty, because then it doesn't know where to redirect.

I checked my theme, there is no other reference to googlefont except to enqueue so I'm not doing anything to mangle it. | It looks like the URL is getting parsed somewhere and whatever does the parsing is probably internally only able to deal with one parameter for a particular name, so just keeps the second value for the family parameter.
As you have a valid usecase for having two parameters with the same name, you might want to file this as a bug.

A recent update to one of the plugins I use broke my multisite blog and in the process of debugging it, all of the plugins got disabled. Now I have to try to figure out which plugins used to be enabled, but that's a big chore for various reasons.
I've probably got at least one backup since the last time I toggled plugin, but I don't know where WordPress stores plugin state information for a multisite blog.
I tried dumping the whole WordPress database to try to search for the plugin state settings, but the thing is too much of a monster to manually search through, especially since most search terms return too many results to be practical.
Does anybody know where WordPress stores the state of plugins? Does it store them in every sub-blog's settings or is there a master one? What about network-enabled plugins? | I found it. It's in the `active_sitewide_plugins` value of the `wordpress_sitemeta` table. | stackexchange-wordpress | {

How to change avatar of the comment author using comment ID?
One visitor commented on one of my post as a guest. Now, i want to change avatar of this comment using comment ID. Comment ID of the comment is 1092. How can i change avatar of the comment using comment id?
Actually i want to change avatar for couple of comments.
Any help would be greatly appreciated. | You can use `pre_get_avatar` filter to manipulate comment avatar html and stop WP from getting a default avatar for the comment.
> _Passing a non-null value will effectively short-circuit get_avatar(), passing the value through the ‘get_avatar’ filter and returning early._
E.g.
add_filter( 'pre_get_avatar', 'my_filter_pre_get_avatar', 10, 3 );
function my_filter_pre_get_avatar( $avatar_html, $id_or_email, $args ) {
if ( is_a( $id_or_email, 'WP_Comment' ) ) {
// Add more cases with elseif or use a switch statement here
if ( '1092' === $id_or_email->comment_ID ) {
// set avatar to whatever html you want
$avatar_html = '<img class="avatar" src="" alt="Custom avatar">';
}
}
return $avatar_html;

Wordpress admin display post type tags as checkbox
I used Wordpress ACF plugin to created a post type called `resource`, also I created two tag categories named `resource-type` and `resource-topic`, I can added in those tags in the post by the enter certain key in input box, but if the input is mistype, a new tag will auto added in the list, this is not what I want and I think of make the tags as checkbox so that it would easily know what tags is available and reduce the mistype error, is it possible to change like this way?
![enter image description here]( | Have you considered changing them to Categories? Categories and Tags are essentially the same thing, just that Categories have a Hierarchy. Category selection is via a Checkbox so you will have more control over what is selected.
**Update** If you have used the function 'register_taxonomy' to create your Tags then you only need to add or adjust one variable - 'hierarchical' - which needs to be set to true. See: Codex information on register_taxonomy
If you used a plugin to create the Taxonomies it should have a similar option. Remember to backup your website before you make any changes. | stackexchange-wordpress | {

Conditional redirect to several pages
Suppose I have these WordPress pages:
* `page-A`
* `page-B`
* `page-C`
and a published page `page-main`.
**My question:**
The clients see and access only `page-main` which is in the end _virtual_ \- it doesn't exist. Accessing this `page-main` page should redirect to **one** of the above mentioned pages A-C, depending on some conditions which are not important for this question.
How can I achieve it? | So you need this to happen before Wordpress has output anything at all, otherwise you won't be able to send a redirect.
A way to achieve this is with the `template_redirect` hook, documented here: <
The example from that docs page is more or less exactly what you want. I've edited it a little bit for your question:
function my_page_template_redirect() {
if ( is_page( 'page-main' ) ) {
if ( $some_condition ) {
wp_redirect( home_url( $pageA ) );
} else {
... other caeses here with redirects to other pages
}
}
}
add_action( 'template_redirect', 'my_page_template_redirect' );
You'd need to add that to your functions.php or a plugin. | stackexchange-wordpress | {

How do I make reusable content blocks for header and footer when using Wordpress headless with another front-end?
I'm setting up a Wordpress project with Gatsby as frontend, and also using ACF for content. But I wonder how you would setup global content parts like header, footer, or any other kind of content that is being used globally throughout the website? For example both HOME and ABOUT pages need to have their "own" content, but also shares some specific blocks with same content.
I need to be able to edit the content for my header like setting up links to internal pages, be able to edit footer content (like text, an image etc), and for any other global blocks I'm looking for a way to setup them like title, text, maybe an image and so on (ACF control kind of...)
Please help me out!
Thanks | ACF has the ability to create a 'Theme Options' page which you can then use to conveniently centralise options for things like headers and footer etc..
ACF Options Page information
As Jacob Peattie rightly points out, how you integrate this into Gatsby is outside of the scope of WPSE and may require custom development. However, providing you can inject custom code into these areas, via a function, shortcode or custom widget etc., using an ACF Options Page to control that content works nicely and is worth exploring. | stackexchange-wordpress | {

Call to undefined function insert_with_markers
I'm experimenting with creating a function to write code into htaccess (I understand the security issues associated). I'm currently using the function insert_with_markers() as a starting point however its throwing a 'call to undefined function' error.
I am using it within a function that is only running whilst logged into the Admin Dashboard.

Setting posts_per_page for taxonomy term template
I have a custom taxonomy term page set up to display posts associated with that term (taxonomy-insight_type-academia.php). I figured I could use the following to limit the posts on that page based on code found here:
<
add_action( 'pre_get_posts', function( $query) {
if ( $query->is_tax( 'academia', 'insight_type' ) ) {
$query->set( 'posts_per_page', 1 );
}
} );
I have added the term to the taxonomy but it doesn't seem to work. I can get it to work for the taxonomy, but not the term.
Is there a way to do this?
Thanks | The taxonomy template you have (`taxonomy-insight_type-academia.php`) is in the form of (`taxonomy-{taxonomy}-{term}.php`), and the format for `is_tax()` is `is_tax( '<taxonomy>', '<term>' )`, so in your `pre_get_posts` callback, you should:
// Use this.
if ( $query->is_tax( 'insight_type', 'academia' ) )
// Not this.
if ( $query->is_tax( 'academia', 'insight_type' ) )
Additionally — to avoid conflict with other queries, you should also check if the current query is the main one or not, and also check if it's an admin-side request.
if ( ! is_admin() && $query->is_main_query()
&& $query->is_tax( 'insight_type', 'academia' )
)

At first glance, it just seems unnecessary | Yes, you can safely delete that file. It's a template of what a minimal `wp-config.php` looks like, so as soon as you have a working wp-config, you don't need it.
It will never be restored unless you reinstall Wordpress from scratch, e.g. by downloading and unpacking a clean Wordpress installation.

Detach site from multisite (turn off multisite)
I have a series of wordpress sites which live under one multisite:
- **My multisite**
* Website A
* Website B
* Website C
* Website D
I am going to be rebuilding the site and as part of the new build, we don't need the multisite confiugration but I need all the content of one of the site as it's rather large.
Essentially, what I want to do is have ' _Website C_ ' as a single site on it's own, websites ' _A_ ',' _B_ ' and ' _D_ ' can be deleted.
Any sort of multisite functionality needs to be removed and it needs to work as a single WP site.
The domains are as follows:
* Website A - www.website.com/de
* Website B - www.website.com/es
* Website C - www.website.com/
* Website D - www.website.com/ru
This should hopefully make any database changes easier as the new site will be: www.website.com/ | I'd just export all content from the site you want to keep. Then create a new WP instance, import that exported data, tweak as required.
Once the site is OK, make the new site active for the desired domain name (in your hosting, point the domain to the new site's folder). No messing with databases required.
**Added 31 July 2020**
Another way: Use the Clone plugin from Automatic to export subsite. Install the plugin as superadmin. Then admin to the subsite and use the Clone plugin to back up everything.
Create a new WP instance (single-site), then install the Clone plugin there. Then import the backup you made of the subsite into the new site via the plugin. Make sure you remember the admin credentials, as everything on the new site will be replaced during the restore process.
Everything from subsite will now be on the new site including themes, plugins, settings and content. | stackexchange-wordpress | {

How to hide Wordpress users' names externally?
I have several users creating posts in Wordpress, but I don't want any of their names to appear publicly. On the site, I want it to only say By: Website Editor.

Can I alter the main loop to 'orderby' a custom callback?
I have a custom post type where the `title` is a name, and I want to sort the loop by the last word in `title`, the surname.

Thanks! | No you can't pass a callback function. Callback functions are PHP, so they can't be run in MySQL. For that to work it would need to query the results from the database first, but you'd get the wrong results because they're unsorted.
You would need to use the `posts_orderby` filter to do this as part of the SQL query:
add_filter(
'posts_orderby',
function( $orderby, $query ) {
if ( ! is_admin() && $query->is_post_type_archive( 'post_type_name' ) ) {
$orderby = "SUBSTRING_INDEX(post_title, ' ', -1) ASC, post_title ASC";
}
return $orderby;
},
10,
2
);
That uses the `SUBSTRING_INDEX()` MySQL function to order results by everything after the ~~first~~ last space in the post title, and then by the post title so that results with matching surnames are sorted by first name. | stackexchange-wordpress | {

), $atts );

Having a template per category? Bad for server overhead?
I understand that you can create (as per the WordPress Hierarchical Structure) a specific template to load a specifc template.
For example:
category-new-york.php
^ this is a priority over simply:
category.php
My question is, would creating a template PER US State be a "bad idea?"
So, I would have:
category-alabama.php
category-arizona.php
category-akansas.php
etc etc
I say "bad practice" because perhaps I am just adding a ton of overhead that WordPress has to loop through templates - or is it not a huge problem? Would the overhead be nominal?
Thanks | > I say "bad practice" because perhaps I am just adding a ton of overhead that WordPress has to loop through templates - or is it not a huge problem? Would the overhead be nominal?
No, there won't be an extra performance cost because that's not how the template loading works. WP always runs through the template hierarchy from most specific to most generic, testing if the file exists as it goes along. It doesn't "loop" through them.
As for creating a template for every US state, I would advise against it, mainly because it means your folder will have a lot of files making it difficult to navigate in the editor, and when you want to make a change you have to update every single state.
You'd be better off making a single generic state template, or better yet, add a state taxonomy and create `taxonomy-state.php` instead of repurposing categories. | stackexchange-wordpress | {

How do I check if I can use the allowed_block_types filter?
For a WordPress theme I deregister a few blocks for Gutenberg (in fact, I only register the ones I need).
For this, I use a filter:
add_filter( 'allowed_block_types', 'amb_allowed_block_types' );
This filter hooks into a function like this:
function amb_allowed_block_types( $allowed_blocks ) {
return [
'core/paragraph',
'core/image',
'core/heading',
'core/gallery',
...
This works nice. But I don't want to use this filter if it is being used on a WP theme that doesn't have Gutenberg enabled. How can I make sure that this filter is only being used on Gutenberg sites?
Many thanks! | You can check if the current theme supports Gutenberg blocks inside your function

Should I use docker in wordpress production?
My question is, is it a good idea to use docker for a big woocommerce website (more than 100k products)? Or will this incur a noticable performance cost compared to running wordpress straight on the VPS (without containerization)? | > My question is, is it a good idea to use docker for a big woocommerce website (more than 100k products)?

A VPS doesn't run on bare metal, the V stands for Virtual, so it'll either be a Virtual Machine, or a container of some sort.

How to allow WordPress updates to only one specific administrator?
I found a code to prevent WordPress update for certain user role:
add_action( 'init', function () {
if ( ! current_user_can( 'administrator' ) ) {
add_filter( 'pre_site_transient_update_core', 'disable_updates' ); // Disable WordPress core updates
add_filter( 'pre_site_transient_update_plugins', 'disable_updates' ); // Disable WordPress plugin updates
add_filter( 'pre_site_transient_update_themes', 'disable_updates' ); // Disable WordPress theme updates
}
} );
What about allowing to update for only one user? | **SOLUTION:**
We take this code and paste it to functions.php :
function createit_hide_upd_for_other_adm_users() {
$current_user = wp_get_current_user();
if ( 777 != $current_user->ID ) { //change the user ID
add_filter( 'pre_site_transient_update_core', 'disable_updates' );
add_filter( 'pre_site_transient_update_plugins', 'disable_updates' );
add_filter( 'pre_site_transient_update_themes', 'disable_updates' );
} else {
}
}
add_action( 'init', 'createit_hide_upd_for_other_adm_users' );

Why does WordPress want a 512×512 pixel site icon
I get that a site icon needs to be square, but I don't know why it needs to be as large as 512×512 or larger.
Can anyone advise why is this, and/or where that image would be used at a resolution higher than that of a favicon (which I understand to be 48×48px or smaller) and what would be the consequences of using a lower resolution image there? | The site icon in WordPress is worked as a favicon.
And the knowledge about the favicon is mostly limited to 16×16 or 64×64 pixels. But this StackOverflow thread shows there's a necessity of a 114×114px favicon for Retina Opera, and a 200×200px favicon for Mobile Opera Speed Dial.
The necessity of such a larger icon is mostly to support retina displays, where it requires larger output, and smaller favicon can get pixelated. This article by Thomas Fuchs has a mention of 512×512px retina-ready favicon.
And I found this article with its comments stating that:
> 512×512px icon in the web manifest to support browser loading splash screens
Also found mention of other sizes like 192×192px, 228×228px etc.
So, with a maximum 512×512px Site icon, WordPress has all the ease to display it in different devices in different display ratios.

How to target all woocommerce categories that don't have any subcategories in them?
I want to target all pages (product categories) that are displaying the products themselves.
My woocommerce settings set to show only categories/subcategories (unless there are none) and then by default the products grid is displayed on the page.
`is_product_category()` function doesn't help since it also targets the parent categories which don't have direct products in them.
Most of my categories that don't any subcategories in them are grandchildren categories if it matters for the answer.
How can I achieve it and to use it in woocommerce hooks? | You can use the `woocommerce_products_will_display()`. This function returns `true` if the current shop page is going to display products. This will be the case if your shop pages are set to display products or subcategories _and_ products, but it will be `false` if the shop pages are set to display subcategories only, and the current category has subcategories.
if ( woocommerce_products_will_display() ) {
// Products are showing.
} else {
// Products are not showing.
}
The `woocommerce_get_loop_display_mode()` is similar, but can let you know whether subcategories are also displaying:
switch ( woocommerce_get_loop_display_mode() ) {
case 'products':
// Products are displaying.
break;
case 'subcategories':
// Subcategories are displaying.
break;
case 'both':

how to assign content to a different author while loading content
I am new to WordPress and am learning the platform on the fly. We are in the process of converting a large non-WordPress site to the WordPress platform. In the process, we have several people updating and loading content into the new site. As a result, all the content is being assigned to the individual loading the content.
**My Question is Two-fold**
**1st]** I am under the impression that I can reassign the content to the appropriate author through a mysql query/update script I write... Is this a correct Assumption?
**2nd]** Is there a way to add an "author" selection box to the post/page form where the content loader could simply select the correct author and then manipulate the parsing process so that WordPress recognizes the selected author and assigns the content to them instead of the loader? | Just to add to what MozBoz has already said, you can also set the author from the post / page in WP directly. You can usually do this from the editor itself, but there are a lot of page builders available, so I'd suggest going to WP Admin and to your **All Posts** , hover over the post you want to set the author of and select **Quick Edit**. This will pull down a tray of options, one of which will be an author dropdown where you can select the posts author from all of the users on your site. | stackexchange-wordpress | {

add_action('publish_to_draft', 'doStuff')
function doStuff() {
// do stuff here
}
Maybe there is something I am missing, but I wanted to check that these are the correct hooks to use. | Yes, these are probably the right calls to use for what you want.

}
Then using the quick edit in the posts list to change a published post to draft, and this hook definitely ran at that point and set this option in the database.

How to show the error causing the 'There has been a critical error on your website'?
I'm getting the error: 'There has been a critical error on your website. Learn more about debugging in WordPress.'.

define( 'WP_DEBUG', true );

how to get a list of all top level pages

Can you Use the Rest API to query a custom database table
I am new to the wp platform and just learned about the Rest Api. I am creating a plugin that will allow the user to access a note keeping system which I plan to manage in a custom database table. Is it possible to manage the CRUD through the Rest Api or is the Rest Api reserved for the core WordPress database tables? | Wordpress has no system of assigning privileges or access to control to _code_ that runs in functions.php or in an enabled plugin.
Therefore if you can get code to run into functions.php or a plugin in your Wordpress environment, you can do **anything** that you can do in PHP in your web hosting environment, and this includes anything at all in Wordpress.
So in your case, once you make your REST API endpoint work, the PHP there can do absolutely anything. You could access the table through the $wpdb object to use Wordpress's database connection and database helper functions. Or you could if you wanted to write your own PHP from scratch using direct mysqli_ calls if you wanted -- this might be advisable if e.g. you would like some of your application logic to be independent from WP. | stackexchange-wordpress | {

get_posts() SQL Injection

In most cases you don't, `get_posts` calls `WP_Query` internally, and `WP_Query` performs some sanitization, namely via `wpdb->prepare`.
* * *
However, for what you're trying to do, this is the wrong approach. Just use a standard `search.php` template with a standard post loop, and use `input` fields that have the same names as the parameters for `WP_Query`. WP will automatically filter as a result of them being added to the URL. There is no need for a custom page template with a custom query and custom URL parameters.

Will revisions be retained when converting to a multi-site?
Will revisions be retained when converting to a multi-site?
We’re looking to convert a WordPress site to a multi-site, and the client we’re working with is very conscious that they don’t want to lose any revisions data.
I can’t find anything in the codex about data loss when converting to a multi-site, but is it a possibility that we might lose some of this data when converting the site?
Thank you | Revisions are stored as posts in the `*_posts` table(s). This shouldn't be touched during a conversion to Multisite.
I just did a quick test on my local machine:
* Installed WordPress
* Added a couple pages and posts
* Revised the pages and posts
* Made sure the revisions were stored in the DB
* Ran the Multisite conversion from the command line (`wp core multisite-convert`)
* Checked to make sure the revisions were still stored in the DB
It appears that the conversion did not affect the revisions at all.
However, note that _your mileage may vary_. I'd recommend doing a full database backup before running the conversion to Multisite. (I'd recommend doing that in any event, of course.) | stackexchange-wordpress | {
