get_sub_field returns bool (false)

hello,
I have a problem on my website, when I try to get the repeater subfield, the loop only finds the value of the first field which is a radio button, for the following ones I get nothing, and when I try to display these fields with the var_dump I find bool (false). this problem concerns only one repeater among the others.

My PHP version is 7.4


<?php

if ( have_rows('mb_hairstyle_tabs_repeater') ) :
                $i = 0;
                
                while ( have_rows('mb_hairstyle_tabs_repeater') ) : the_row();
                    $i++;
                   
                    if (have_rows('mb_tab_products')) :

                        while ( have_rows('mb_tab_products') ) : the_row();
                            ?>
                            <?php
                             
                            $hairstyleTitle     = get_sub_field('mb_hairstyle_title');
                            $hairstyleText      = get_sub_field('mb_hairstyle_text');
                            $hairstyleImg       = get_sub_field('mb_hairstyle_illustration');
                            
                            $productTitle       = get_sub_field('mb_product_title');
                            $productText        = get_sub_field('mb_product_text');
                            $productImg         = get_sub_field('mb_product_illustration');
                            $productBtnLabel    = get_sub_field('mb_product_button_label');
                            $productExternalBtn = get_sub_field('mb_product_external_link');
                            $productImgSize     = 'full';
                            $position           = get_sub_field('mb_hairstyle_product_position');

endwhile;
                    endif;
                endwhile;
            endif;
            ?>

You cannot get sub fields of the first repeater inside of the nested repeater loop.


if (have_rows('repeater')) {
  while (have_rows('repeater')) {
    // you can access sub fields of "repeater" here
    if (have_rows('nested_repeater) {
      while (have_rows('nested_repeater) {
        // you can access sub fields of nested repeater here
        // you cannot access sub fields of "repeater" here
      } // end while nested repeater
    } // end if nested repeater
    // you can access sub fields of "repeater" here
  } // end while "repeater"
} // end if "repeater"

yes i am trying to get the subfields of the nested repeater, and when i try to get it by this method it returns the value:
get_field(‘mb_collection_strates_3_mb_hairstyle_tabs_repeater_0_mb_tab_products_0_mb_hairstyle_title’);

Looking at the meta key you have
- a repeater of some kind (repeater or flex field) named “mb_collection_strates”
- a nested repeater named “mb_hairstyle_tabs_repeater”
- and a second nested repeater named “mb_tab_products”
Where is the loop over “mb_collection_strates” being performed?

It is assigned in another file that calls this one :

if(have_rows('mb_collection_strates')):
            while(have_rows('mb_collection_strates')): the_row();
                $layout = get_row_layout();
                echo clrz_get_template_part('collections-level-one', $layout);
            endwhile;
        endif;

NB : the second nested repeater loop call just the radio button mb_hairstyle_product_position and does find any other field

I don’t see where ‘mb_hairstyle_tabs_repeater’ is part of a layout. How are are you including the repeater in a layout? clone? What are the clone settings?

I have looked several times and I don’t see why the values would not be shown, unless the values to not exist. Can you confirm that the values are actually being saved in the database? After you edit the page where this is located are the values loaded into the fields to edit?

in my template page I have this loop:

<div class="row">
      <?php
        if(have_rows('mb_collection_strates')):
            while(have_rows('mb_collection_strates')): the_row();
                $layout = get_row_layout();
                echo clrz_get_template_part('collections-level-one', $layout);
            endwhile;
        endif;
      ?>
    </div>

which uses files one of them contains this code

<div class="strate-collection-hairstyle strate-collection-hairstyle--mobile margin-bottom-xl">
    <div class="container-fluid">
        <div class="row collection-hairstyle-container js-hairstyle-tabs tabs">

When I modify the value of one of it’s field, and after modifying the page I still find the old value, also when create a new field and I try to fill it it always remains empty.

I think you are running into an issue with a php setting, possibly max_input_vars or max_input_nesting_level or maybe post_max_size. More than likely it is max_input_vars.

Hello,
I increased the quotas of the max_input_vars, max_input_nesting_level and post_max_size, but the problem persists.
is there another probable source of the problem?

Thank you,
