ACF filter to customize WYSIWYG field wrapper attribute

I am trying to customize the ACF field widths via load_fields filters for certain field types. I successfully customized the image type with:

function acf_image_width($image_width) {
$i_width = '40';
if(empty($image_width['wrapper']['width'])) {
$image_width['wrapper']['width'] = $i_width;
} }
add_filter('acf/load_field/type=image','acf_image_width', 10);

This is pre-populating the image type wrapper attribute width with a value of 40.

For the WYSIWYG field, I did the same but I'm getting an error. I did this but I'm sure I'm getting the field type wrong for WYSIWYG.

function acf_wysiwyg_width($content_width) {
$c_width = '60';
if(empty($content_width['wrapper']['width'])) {
$content_width['wrapper']['width'] = $c_width;
} }
add_filter('acf/load_field/type=wysiwyg','acf_wysiwyg_width', 10);

I have tried acf_the_content and that did not work either. Any help with the field type is appreciated.

When using the acf/load_field filter, as per the documentation link below...

https://www.advancedcustomfields.com/resources/acf-load_field/

The acf/load_field filter function parameter is...

$field (array) The field array containing all settings.

So both of your function params are wrong. Don't be defining $image_width and $content_width as your functions parameter, as this will just confuse things, because you are actually passing full $field settings as an array.

Just pass $field param array as $field instead, knowing the acf/load_field filter will pass the field settings into $field param as an array.

Then use $field array to update, set or override current array values, and make sure you always return $field at the end of your acf/load_field filter function...

function acf_wysiwyg_width($field) {

  // dump field param contents so you can see the returned data
  // remove 2 lines below once your happy you know what your setting
  var_dump($field);
  exit;

  // then use $field param like this to override the array value (if these keys actually exist)
  $field['wrapper']['width'] = 60;

  // you must always return function param $field for acf/load_field filter to finish the job!
  return $field;

}
add_filter('acf/load_field/type=wysiwyg','acf_wysiwyg_width', 10);
