Issues Retrieving ACF Field Values in a Code Widget

1

Hi all,

I’m using the PHP Code Widget to generate custom JS for a specific calendar setup. However, I’m encountering an issue where I can’t retrieve data from the ACF fields.

Although the fields appear in var_dump, I’m not getting any actual values.

Here’s a code snippet:

if (have_rows('b2c_repeater')): 
    while (have_rows('b2c_repeater')): the_row();
        
        $erlebnis_buchung_block = get_sub_field('erlebnis_buchung_block'); //Group
        var_dump($erlebnis_buchung_block);
    endwhile;
endif;

The output looks like this:

array(4) { 
    ["fareharbor_id"]=> string(0) "" 
    ["fareharbor_voucher_id"]=> string(0) "" 
    ["sprache_anzeigen"]=> string(2) "Ja" 
    ["platz_anzeigen"]=> string(2) "Ja" 
}

I’ve checked multiple times to ensure I’m iterating through the correct repeater and fields, and everything seems correct.

Oddly enough, if I add the same dynamic fields in another widget, the correct data is displayed. The issue persists whether I place the code in functions.php or use a code-snippets plugin.

Does anyone have any idea what could be going wrong?

Thanks in advance!

okay … i think i found why:

You cannot mix get_sub_field() and have_rows().

never think about this …
