Add rows to repeater

  I’m working through some logic to dynamically build out repeater rows from other acf field groups, that are also repeaters. Getting the fields and sub fields isn’t a problem. I’m just needing some guidance on pushing the values from other field groups to my other field group that’s a repeater (which also has nested repeaters). Here is what I have come up with so far. From my understanding I need to use an array of arrays to make this happen. I can actually get new row to be added, but it doens’t populate with any of the data.

  
  add_action('acf/init', 'bb_populate_boat_fields');
  
  function bb_populate_boat_fields() {
      $boats_repeater = 'field_64b3015ff26f0'; // field key of repeater
  
      $boat_line_rows = array();
      $boat_line_repeater_rows = array(); 
      $boat_line_model_repeater_rows = array();  
  
      while ( have_rows( 'boat_lines', 'option' ) ) : the_row();        
          $line_value = get_sub_field('line_name');
          $line_name = get_sub_field('label');
          $line_image = get_sub_field('image');
          
          $boat_line_repeater_rows[] = array(
              'field_6472614b658a8' => $line_value,
              'field_64726198658a9' => $line_name,
              'field_64b55db947157' => $line_image,
          );         
  
          while( have_rows('model') ) : the_row();
                // Get sub value.
                $model_value = get_sub_field('value');
                $model_name = get_sub_field('name');  
                $model_image = get_sub_field('image');  
                
                $boat_line_model_repeater_rows[] = array(
                  'field_6472622b658aa' => $model_value,
                  'field_64726257658ab' => $model_name,
                  'field_64b498184c717' => $model_image
                );
  
          endwhile; 
  
          // nested array for every row of repeater
          $boat_line_rows[] = array(
              // field key => value pairs for each sub field            
              'field_64711c7f0ce91' => array(
                  // nested repeater
                  // field key => value pairs for each sub field
                  $boat_line_repeater_rows,
                  'field_647180fd537f2' => array(
                      $boat_line_model_repeater_rows
                  ),
              ),
              // next row in nested repeater
          );
      endwhile;    
  
      //wp_die(var_dump($boat_line_rows));
      
      update_field( $boats_repeater, $boat_line_rows, 'option' );
  }

  You’re code is not easy to follow, but I think that your issue is that you are attempting to use [] to assign values directly to the array as you get them. To build a nested array you need to build the sub array and then add it to the main array all at once.

  Here is a simple example

  
  // initialize the array to hold the repeater value
  $value = array();
  
  // main repeater
  while (have_rows('main_repeater')) {
    the_row();
    // start building this row from sub fields of the main repeater
    $row = array(
      // add fields of the main repeater
      'field_key' => get_sub_field('field_name')
    );
    // sub repeater
    if (have_rows('sub_repeater')) {
      // initialize the sub repeater array
      $sub_repeater = array();
      while(have_rows('sub_repeater')) {
        the_row();
        // add a row to sub repeater array
        $sub_repeater[] = array(
          // add fields from sub repeater
          'field_key' => get_sub_field('field_name')
        );
      } // end sub repeater while
      // add sub repeater to the current row
      $row['sub_field_repeater_key'] = $sub_repeater;
    } // end sub repeater if
    // add the new row to the main repeater
    $value[] = $row;
  } // end main repeater while

  Thanks John, I copied in your example but it still doesn’t seem to be working quite right. I can create correct number of row, but they are empty. Maybe a screenshot would help show what I have?

  Here is what the logic I have produces:

  John, I actually got this working now.

  // start building this row from sub fields of the main repeater
      while ( have_rows( 'boat_lines', 'option' ) ) : the_row();        
          $line_value = get_sub_field('line_name');
          $line_name = get_sub_field('label');
          $line_image = get_sub_field('image');
          
          $boat_line_repeater_rows = array(
              // add fields of the main repeater
              'field_64dfd8bf4bc3f' => $line_value,
              'field_64dfd8bf4bc40' => $line_name,
              'field_64dfd8bf4bc41' => $line_image,
          );   
  
          // sub repeater        
          if ( have_rows('model') ) {
              // initialize the sub repeater array
              $boat_line_model_repeater_rows = array();
  
              while( have_rows('model') ) : the_row();
                  // Get sub value.
                  $model_value = get_sub_field('value');
                  $model_name = get_sub_field('name');  
                  $model_image = get_sub_field('image');  
                  
                  // add a row to sub repeater array
                  $boat_line_model_repeater_rows[] = array(
                      // add fields from sub repeater
                      'field_64dfd8bf4bc43' => $model_value,
                      'field_64dfd8bf4bc44' => $model_name,

                  );
  
              endwhile; // end sub repeater while
  
              // add sub repeater to the current row
              $boat_line_repeater_rows['field_64dfd8bf4bc42'] = $boat_line_model_repeater_rows;
          } // end sub repeater if
  
          // add the new row to the main repeater
          $boat_line_rows[] = array(

                  $boat_line_repeater_rows
              )

  So here is what the current logic produces:

  array(3) {
      [
          0
      ]=> array(1) {
