Understanding Custom Fields serialized data

EDIT
I found this post https://www.ads-software.com/support/topic/measurement-price-calculator-4/ that is similar to my situation… but is not clear to me ??

Hi @bredaportoni,

How can i use a column on my file (“Length”) to dynamically import different lengts?!

As described in the other post you linked to, you’d have to write custom code that uses our API (see documentation) to achieve this. Unfortunately, I don’t have any example snippets that are specific to this use case, but you may be able to find some inspiration for your code here: https://www.wpallimport.com/documentation/developers/code-snippets/.

Hi and thanks for the reply.
Maybe this must be the case?
but… I’m in trouble, can’t understand how to “translate it” into my scenario…
There is a “add-on service” to have specific aid to make things like this? H
ave you a developer list to contact for this?

Thanks in advance.

I’m trying with this function:

/*
    [TEST] Add length options 
    Based on: https://www.wpallimport.com/documentation/developers/code-snippets/#append-data-to-a-custom-field-instead-of-replacing-it
*/
function options_field_fill($id)
{
    // Get the current value.
    $breda_prod = unserialize(get_post_meta($id, '_wc_price_calculator', true));

    // Fill dimension options
    $breda_prod['dimension'] = array( 
        "length" => array( 
            "options" => array(
                0 => "100",
                1 => "200",
                2 => "300"
            )
        ) 
    );

    // Save it to database
    update_post_meta($id, '_wc_price_calculator', $breda_prod);
}

add_action('pmxi_saved_post', 'options_field_fill', 10, 1);

but only the new array put into the database…
It seems that the previous content of “_wc_price_calculator” are gone.

Hey @bredaportoni,

Unfortunately, we can’t help write/troubleshoot custom code for your project or recommend a developer, but we can leave this thread open in case anyone is able to help.
