How to create multidimensional array in nested loop while?-CodePudding

I have nested loop while and I'd like to create multidimensional array with some datas from these loops Output should be look like:

'productId'=>1
'productImg'=>some_url
'productContent'=> subarray(
     'question1'=>value1
     'answer1'=>value1,
     'question2'=value2,
     'question2'=>value2
)

My code with nested while loops

    if (have_rows('dodaj_pytania_do_produktu')):

        while (have_rows('dodaj_pytania_do_produktu')) : the_row();
            $counter = 1;
            $productID = get_sub_field('nazwa_produktu_faq');
            $productImage = get_sub_field('dodaj_zdjecie');
            $productsData[] = array(
                'productId' => $productID,
                'productImg' => $productImage,

            );
            $product = wc_get_product($productID);
            $productName = $product->get_title();
            // Loop over sub repeater rows.
            if (have_rows('dodaj_pytanie_i_odpowiedz')):
                while (have_rows('dodaj_pytanie_i_odpowiedz')) : the_row();
                    $question = get_sub_field('dodaj_pytanie');
                    $answer = strip_tags(get_sub_field('dodaj_odpowiedz'));
                    $productsData[] = array(
                        'productDesc'=> array(
                        'question' => $question,
                        'answer' => $answer
                        )
                    );
                endwhile;
            endif;
        endwhile;
    else :
        echo "brak faq";
    endif;

    ?>

Now my output create wrong subarray not creating a subarray

CodePudding user response：

There is no hurry to create the array, wait till you have everything, so create the new array at the end of the outer loop, and build a temp array for the productContent array, put it all together at then end

if (have_rows('dodaj_pytania_do_produktu')):

    while (have_rows('dodaj_pytania_do_produktu')) : the_row();

        $productID = get_sub_field('nazwa_produktu_faq');
        $productImage = get_sub_field('dodaj_zdjecie');
        
        $product = wc_get_product($productID);
        $productName = $product->get_title();
        // Loop over sub repeater rows.
        if (have_rows('dodaj_pytanie_i_odpowiedz')):
            $x = 1; // counter
            $pc = [];
            while (have_rows('dodaj_pytanie_i_odpowiedz')) : 
                the_row();
                $question = get_sub_field('dodaj_pytanie');
                $answer = strip_tags(get_sub_field('dodaj_odpowiedz'));

                // build the inner loop content here
                $pc[] = ["question$x" => $question,
                         "answer$x" => $answer
                         ];
                $x  ;
            endwhile;

            // put it all together here
            $productsData[] = [
                        'productId' => $productID,
                        'productImg' => $productImage,
                        'productContent = $pc
                ];

        endif;
    endwhile;
else :
    echo "brak faq";
endif;
