Hi, i want to display Ingredient-Group-Name(textfield) before the nested repeater. But it always fails. Actually, without it this form is fine. But because it’s a form for food recipes so I have to keep showing it.

this my functions.php

   add_filter('acf/pre_save_post' , 'tsm_do_pre_save_post' );
   function tsm_do_pre_save_post( $post_id ) {
   $allingredients = $_POST['acf']['field_1']; // REPEATER
   foreach ($allingredients as $row)
    {
    $groupname = $row['field_2']; //THIS IS TEXT FIELD Ingredient-Group-Name 
    $ingredients_total_unit = $row['field_3']; //   NESTED REPEATER

    // loop through repeater rows
    if( $ingredients_total_unit )
    {
        foreach($ingredients_total_unit as $sub_row)
        {
            // add extra data to row
               $unit = $sub_row['field_3A'];
                $total = $sub_row['field_3B'];
                $ingredients = $sub_row['field_3C'];
                $ingredientsall .= '<li>' . $ingredients . ' ' . $total . ' ' . $unit . '</li>';    
            }

        }   

       $groupnameandingredient .= '<p>' . $groupname . '</p>' . $ingredientsall . ''; // THIS IS WRONG PART

    }

and called again with

<ul>' . $groupnameandingredient .'</ul>

But my post result is

Ingredient-Group-Name AAA
— 111
— 222

Ingredient-Group-Name BBB
— 111
— 222
— 333
— 444

Ingredient-Group-Name CCC
— 111
— 222
— 333
— 444
— 555
— 666

I just want the results as below

Ingredient-Group-Name AAA
— 111
— 222

Ingredient-Group-Name BBB
— 333
— 444

Ingredient-Group-Name CCC
— 555
— 666

Thanks a lot
