ACFs : How to change default values / settings

Using Advanced Custom Fields,

  1. Say anytime i want an image field, i need it to output an array as default.
  2. Or anytime i use a wysiwyg, i don’t want it to show the media button
  3. Need a textarea ? i want it with no formatting as default.

How can i change these defaults ?

Any plugins or snippet example for functions.php ?

Thank you !!

Johan

OK, for force the setting of an ACF field, you should use another hook, named acf/update_field/. It works like those before :

add_filter('acf/update_field/type=wysiwyg', 'my_custom_acf_filter_wysiwyg', 1);
function my_custom_acf_filter_wysiwyg($field){
    $field['media_upload'] = 0;
    return $field;
}

And you can use these other for target specific fields : 

acf/update_field/name={$field['name']}
acf/update_field/key={$field['key']}

When the settings will be saved, their will be take your custom value.

I'am using ACF Pro, so my answer could not works for you...

For your front fields, you can use the acf/format_value hook, and change the $field params you want :

Textarea example:

add_filter('acf/format_value/type=textarea', 'my_custom_acf_filter_textarea', 1, 3);
function my_custom_acf_filter_textarea($value, $post_id, $field){
    remove_filter('acf/format_value/type=textarea', 'my_custom_acf_filter_textarea', 1);
    $field['new_lines'] = '';
    $newvalue = acf_format_value($value, $post_id, $field);
    return $newvalue;
}

Image example:

add_filter('acf/format_value/type=image', 'my_custom_acf_filter_image', 1, 3);
function my_custom_acf_filter_image($value, $post_id, $field){
    remove_filter('acf/format_value/type=image', 'my_custom_acf_filter_image', 1);
    $field['return_format'] = 'array';
    $newvalue = acf_format_value($value, $post_id, $field);
    return $newvalue;
}

Note that you can also force the options for specific fields with this hooks :

acf/format_value/name={$field['_name']}
acf/format_value/key={$field['key']}

And for your backend display, use acf/prepare_field :

WYSIWYG example:

add_filter('acf/prepare_field/type=wysiwyg', 'my_custom_acf_filter_wysiwyg', 1);
function my_custom_acf_filter_wysiwyg($field){
    remove_filter('acf/prepare_field/type=wysiwyg', 'my_custom_acf_filter_wysiwyg', 1);
    $field['media_upload'] = 0;
    return $field;
}

For the admin display, you can also target specific fields with :

acf/prepare_field/name={$field['name']}
acf/prepare_field/key={$field['key']}
