Count words in post with many ACF blocks-CodePudding

I am trying to count the amount of words there are on a given post on a WordPress install.

When I target the content

$word_counter = str_word_count(the_content());

It works, but this amounts to a small part, the rest it's made out of various ACF layout blocks, they are all gathered by get_template_part and required into the single.php file.

Is there a way I could count the amount of words that all these blocks generate, from the single.php page?

My problems is that I have been going into each layout template, and gone through each field to count the words:

app/builder.php

if (get_field('layouts_templates', 'option')):
  $word_counter_main = 0;
  while (have_rows('layouts')) : the_row();

    $word_counter_main = $word_counter_main   str_word_count(get_sub_field('content'));

    if (get_row_layout() == 'template') {
     $template_builders[get_sub_field('layouts_template')] = null;                 
    }

  endwhile;
endif;

But I dont know how to pass it back to single.php to add all the word counters into a total.

single.php

...
// layouts
get_template_part('app/builder');

UPDATE

There are a few more templates with in the layouts, this is the structure

array(9) {
  ["layouts"] =>
  array(3) {
    array(12) {
      ["acf_fc_layout"]=> "main-content"
      ["acfe_flexible_toggle"]=>  ""
      ["acfe_flexible_layout_title"]=>  ""
      ["content"]=> "Need to collect the content here"
    }
    array(2) {
      ["acf_fc_layout"]=> "car_details"
      ["cars"]=>
      array(3) {
        [0]=>
        array(2) {
          ["name"]=>
          string(23) "Audi"
          ["content"]=> "Need to collect the content here"
        }
        [1]=>
        array(2) {
          ["name"]=>
          string(23) "Seat"
          ["content"]=> "Need to collect the content here"
        }
        [2]=>
        array(2) {
          ["name"]=>
          string(23) "Opel"
          ["content"]=> "Need to collect the content here"
        }
      }
    }
  }
}

I not sure how to get all the contents into one variable

CodePudding user response：

If you want to use your current logic you could create a helper function in functions.php that returns the $word_counter_main per post.

functions.php

function get_current_post_word_count($post_id) {

   $word_counter_main = 0;
   $word_counter_main  = str_word_count(get_the_content($post_id));

   if (get_field('layouts_templates', 'option')):
     $word_counter_main = 0;
     while (have_rows('layouts', $post_id)) : the_row();

     $word_counter_main  = str_word_count(get_sub_field('content'));

     if (get_row_layout() == 'template') {
      $template_builders[get_sub_field('layouts_template')] = null;                 
     }

   endwhile;
 endif;

 return $word_counter_main;
}

single.php

$post_word_count = NAMESPACE\get_current_post_word_count(get_the_ID());

Another approach would be to create a meta field per post that would get updated whenever you update a post, then you could just load the meta field value. That way you wouldn't have to loop through all the content each time you load a post.
