Thanks for great software

Just wondering if this plugin has ever been fuzz tested for user input? I’m not expert in injection, but I notice HTML tags enter into the database fields from user input from the front end:

Would it be wise to consider parsing text lines through sanitize_text_field() and text areas through sanitize_textarea_field()?

I have a website with a taxonomy called “db_themen” with different values. The posts from from my webiste are assigned to these taxonomy values from “db_themen”.

On my website, a user can choose in his frontend user profile which “db_themen” he is interested in and save this input. This works through an ACF field of the type “Taxonomy” (field name: “meine_themen”), which is linked to the taxonomy “db_themen”.

According to his input, only posts that are assigned to the same taxonomies are supposed to show on the frontend archives (Elementor archives Loop Grid) for this user.

I tried to code something within my functions.php, but I am a total beginner. The only thing this code does is hide all posts entries in the backend:

function abfrage_meine_themen($query) {
    if ($query->is_main_query() && is_user_logged_in()) {
    $ausgewaehlte_themen = get_field('meine_themen', 'user_' . get_current_user_id());
        if ($ausgewaehlte_themen) {         
            $tax_query = array(
                array(
                    'taxonomy' => 'db_themen',
                    'field'    => 'slug',
                    'terms'    => $ausgewaehlte_themen,
                ),
            );
            $query->set('tax_query', $tax_query);
        }
    }
}
add_action('pre_get_posts', 'abfrage_meine_themen');

Can someone please tell me where my mistakes are? I am sure there are several

In my case, if a user types ‘london’ in the search box they are presented with:
Hen party London
Greater London
British Museum London
Natural History Museum London
London – West End
London Treasure hunts

These contain 1,6,3,3,3,6 products respectively.

1. What determines the order in which these categories appear? – as I might have expected those that begin with ‘London’ to appear first

2. What, if anything, can I do to influence or change this order?

3. If the user types ‘Hen London’ then no results appear. Do you only accept exact matches of consecutive characters? Or is there a way to influence or change this?

4. If the user searches for ‘hen’ then words containing ‘hen’ are also returned. How (if at all) does the algorithm differentiate between words that start with the search characters (e.g. hen, henna) end with the search characters (e.g. then) or contain the search characters (e.g. phenol)?

5. Is the user able to do a Boolean search?, e.g. ‘Museum OR History’; ‘London’ AND ‘Museum’

Some of these are fairly fundamental to usability but I couldn’t find any information in the documentation – hence my questions.

Hope you can help please.

so I have a table on my website and I would like to allow users to change values row by row in boolean columns directly in the front-end table and update their input in the database. Once they hit refresh their input is retrieved and displayed correctly.

is that possible with the plugin?

thanks in advance for your help

Here’s an example: https://www.checkli.com/checklists/view/5f6ba4b76c6d5

Complete newbie so hope this is in the right place.

Is there a way to have a user fill out a form and then make a new page/post from that form?
i.e. if Sam filled out a form asking what their favourite dog and colour was, could you create a new page/post titled Sam’s favourites and list their choices?

Thanks for any help!!
