  • I’m looking at this thread: https://support.advancedcustomfields.com/forums/topic/issues-with-add_rows-and-flexible-content/

    According to this, as of 2016, add_row on flexible fields weren’t working. Instead, they used update_field, which added new rows? Anyways, I wonder if it has something to do with flexible fields…

    Additionally, I have been thinking that I may be hooking incorrectly in my functions.

    First, the full code for this specific piece: 

    
<?php
/**
 *
 *   Update the content of a field.
 *
 */

class POB_Save_Settings {

  public static function init() {

      add_action( 'wp_ajax_nopriv_save_settings_fields', array( 'POB_Save_Settings', 'save_settings_fields' ) );
      add_action( 'wp_ajax_save_settings_fields', array( 'POB_Save_Settings', 'save_settings_fields' ) );

  }

  public function update_static_content($post_id, $this_count, $the_content){
    //print_r(get_field_objects($post_id));
    $all_fields = get_field_objects($post_id);
    $this_field = $all_fields['content_type']['layouts'];
    $this_row_layout = $all_fields['content_type']['value'][$this_count]['acf_fc_layout'];
    $this_layout = array();
    foreach($this_field as $layout => $key){
      $this_layout[$key['name']] = $key['sub_fields'];
      $this_layout[$key['name']]['key'] = $layout;
    }

    $this_layout_key = $this_layout[$this_row_layout]['key'];
    $label_group_key = $this_layout[$this_row_layout][1]['key'];

    if( have_rows('content_type', $post_id) ) :
      while( have_rows('content_type', $post_id) ) : the_row();
      echo 'content_type while' . '<br>';
      echo get_row_index() . '<br>';
      echo $this_count+1 . '<br>';
        if( get_row_layout() == $this_row_layout && get_row_index() == $this_count+1 ) :
          echo 'true' . '<br>';
          update_post_meta( $post_id, 'content_type_'.$this_count.'_title', $the_content['title']);
          if( have_rows($label_group_key) ) :
            while( have_rows($label_group_key) ) : the_row();
            /*$values = array(
              $this_layout[$this_row_layout][1]['sub_fields'][0]['key'] => $the_content['label'],
              $this_layout[$this_row_layout][1]['sub_fields'][1]['key'] => $the_content['subtitle']
            );
            print_r($this_field);*/
            $label = 'content_type_'.$this_count.'_label_label';//$this_layout[$this_row_layout][1]['sub_fields'][0]['key'];
            $subtitle = $this_layout[$this_row_layout][1]['sub_fields'][1]['key'];//'content_type_'.$this_count.'_label_subtitle';
            echo update_sub_field( 'label', $the_content['label']);
            echo update_sub_field( 'subtitle', $the_content['subtitle']);
            //update_sub_field( array($this_layout_key, 1, $label_group_key), $values, $post_id );
            endwhile;
          endif;
          if( have_rows('css') ) :
            while( have_rows('css') ) : the_row();
            $cssclass = 'content_type_'.$this_count.'_css_classes';
            $cssid = 'content_type_'.$this_count.'_css_id';
            update_post_meta( $post_id, $cssclass, $the_content['classes']);
            update_post_meta( $post_id, $cssid, $the_content['style_id']);
            endwhile;
          endif;
        endif;
      endwhile;
    endif;
  }

  public static function save_settings_fields(){
    if(isset($_POST['to_save'])){
      $post_info = $_POST['details'];
      $post_id = $post_info['postid'];
      $this_count = $post_info['index'];
      $saved_content = $_POST['to_save'];
      $all_content = array();
      foreach($saved_content as $array){
        $all_content[$array['name']] = $array['value'];
      }
      print_r($all_content);
    } else {
      wp_die($_POST.' not set!');
    }
    //wp_send_json($response);
    $foobar = new POB_Save_Settings;
    $isdone = $foobar->update_static_content($post_id, $this_count, $all_content);
    if ( is_wp_error( $isdone ) ) {
        wp_send_json_error( $isdone );
    } else {
      echo 'yay!';
      wp_die();
    }
  }

}

    So I’m using AJAX to send information to this. In my plugin’s functions.php, we got:

    
define('PLUGIN_DIR_PATH', plugin_dir_path(__FILE__));

require_once PLUGIN_DIR_PATH . 'admin/classes/pob-category-walker.php';
include_once( plugin_dir_path( __DIR__ ) . 'advanced-custom-fields-pro/acf.php' );
include_once PLUGIN_DIR_PATH . 'admin/pob-remote-post-class.php';
include_once PLUGIN_DIR_PATH . 'admin/views/panes/pane_layout_radio_buttons.php';
include_once PLUGIN_DIR_PATH . 'admin/classes/pob-save-settings.php';
include_once PLUGIN_DIR_PATH . 'admin/classes/pob-create-field.php';
POB_Remote_Post::get_instance();
Radio_Buttons_Layout::init();
POB_Save_Settings::init();
POB_Create_Field::init();

function update_acf_settings_path( $path ) {
    $path = plugin_dir_path( __DIR__ ) . 'advanced-custom-fields-pro/';
    return $path;
}
add_filter( 'acf/settings/path', 'update_acf_settings_path' );
function update_acf_settings_dir( $dir ) {
    $dir = plugin_dir_url( __DIR__ ) . 'advanced-custom-fields-pro/';
    return $dir;
}
add_filter( 'acf/settings/dir', 'update_acf_settings_dir' );

do_action('acf/input/admin_head'); // Add ACF admin head hooks
do_action('acf/input/admin_enqueue_scripts'); // Add ACF scripts
add_action( 'admin_init', 'add_acf_variables' );
function add_acf_variables() {
    acf_form_head();
}

    With the last pieces (after init of those classes) being added recently, making shots in the dark.

    Could someone perhaps check that I’m hooking properly to update content? Or if I’m missing something there?

    Thanks again, Using this I can verify, by adding in an echo, that it gets through to the label group, using keys I’ve snagged from another array, but when it comes to update_sub_field, whether using the name or field key, it doesn’t work. I’m going to continue checking logs, but nothing is popping up…

    EDIT:

    I tried echoing the result of update_sub_field, and it seems only the first one (for ‘label’) does anything – it returns true, though it doesn’t actually update anything! A bit odd that it both does nothing, and doesn’t continue to the next update_sub_field, is it not?

  • @graphix,

    Thanks for some pointers, but unfortunately this isn’t working for me. I’m curious if it’s because I’m using a Flexible Content Type vs a Repeater?

    I’m able to get the saving to work via WordPress’ update_post_meta function, just using 

    
    $label = 'content_type_'.$this_count.'_label_label';
    $subtitle = 'content_type_'.$this_count.'_label_subtitle';
    update_post_meta( $post_id, $label, $the_content['label']);

    However, I worry that when new content types and repeaters are added in this manner, they may not be ‘registered’ with ACF. I feel I’m missing something important in the structure of my code, as it seems to work for everyone but me!

    From some fiddling, get_fields actually shows me that there is a ‘new’ field added in for each of the groups I updated, e.g.

    
//before updating label in group label
content_type_label_label => ''

    becomes

    
//after updating label in group label
content_type_label_0_label => 'test',
content_type_label_label => ''

    Or something to that effect.
