Features – New data frame for different groups

I have a data frame with the & # 39; Country & # 39; column. Each country has multiple records. I want to write a function in python with pandas so that it can return a separate data frame for each country.

With a country list like: Countries = [& # 39; USA, & # 39; Spain & # 39;, & # 39; France & # 39;],

I can individually

df_us = df [df.country == & # 39; US & # 39;]
df_spain = df [df.country == & # 39; Spain & # 39;],

but how does that work? thank you in advance

Features – Recommended image overlay when changing post status

I have a car rental company in Spain with a WordPress website that uses the MOTORS theme from Themeforest. The topic didn't have all the features I wanted, especially the ability to mark cars as sold.

I managed to add a custom post status. However, I was wondering if I could add a "SOLD" badge overlay to the featured image when the post status changes to "Sales".

The website in question is www.carsinspain.es

Any help is greatly appreciated.

Many thanks,


Features – How do I check if an open page is a toilet related page?

I have to recognize all toilet-related pages (products, individual products, cash register, etc.) on one website.

I added that wp Action in the functions.php and tried it with is_shop() Function, but it doesn't work. Here is the code I tried to do this with

add_action('wp', 'page_loaded');

function page_loaded() {
   if (is_shop()) {
      // Some code here

Is there any way to do this?

Features – Multi-site redirect upload path from Server 2 to Server 1 with Haproxy

I have installed 2 servers with WordPress MultiSite.
I also installed a server with haproxy.

haproxy server:
site - 1:
site - 2:

All requests to the HAProxy server are sent to the other two servers using the round robin method.
Site-1 runs the MYSQL database and Site-2 uses this database.
My problem is that when uploading files, multisite users upload files to the server they are connected to and the file remains in the UPLOADS folder on that server. I connected the upload folder on Site-1 to the Site-2 server using SSHFS. This time some files are loaded, others are not.
Since my english is bad, let me summarize it so there is no confusion.

(I took the clone from Server-1 and got Server-2.)
I want two servers that are already installed to use the same database and upload folder, and of course it works properly.

Features – Precede and display the custom header widget area

So in my functions.php I have a tick according to the topic documentation when I put the content in front of the body. I also create a widget area that I would like to use as the pre-content, as follows:

// create custom header widget area
function wpb_widgets_init() {

    register_sidebar( array(
        'name'          => 'Custom Header Widget Area',
        'id'            => 'custom-header-widget',
        'before_widget' => '
', 'after_widget' => '
', 'before_title' => '

', 'after_title' => '

', ) ); } add_action( 'widgets_init', 'wpb_widgets_init' ); // prepend and display custom header widget area add_action( 'before', 'uncode_child_hook_before' ); function uncode_child_hook_before(){ echo ; }

Something doesn't have to be right with my syntax – I'm a total PHP newbie. Thank you in advance.

Features – Assign a custom author page based on the author role

I have 20 different multi-user custom roles, many of which require an authoring page that is assigned based on their role. I found code here that seems to be useful in finding the role of the author of the article https://wordpress.org/support/topic/custom-author-page-for-custom-role/ and I have found a code here that seems to help me assign the page I want to change the link to the target author. But combining in my functions.php file doesn't work:

if ( is_author() ) {
    $author = get_user_by( 'slug', get_query_var( 'author_name' ) );
    $role = $author->roles(0);
    if ( 'molise' === $role ) { //the name of one custom role

    add_filter( 'author_link', 'new_author_link', 10, 1 );
function new_author_link( $link ) {      
    $link = 'https://example/'; //the link where I want to point when a user click on author below the post

    return $link; //after you've set $link, return it to the filter              


any ideas? thank you in advance
