acf/save_post hook returning funny field names

Hi,

I am trying to get field values after an options page has been saved.

For that I have copied the code from here:

function my_acf_save_post( $post_id ) {
    
    // bail early if no ACF data
    if( empty($_POST['acf']) ) {
        return;
    }
    
    // array of field values
    $fields = $_POST['acf'];

    // specific field value
    $field = $_POST['acf']['kontingent_text'];
}

// run before ACF saves the $_POST['acf'] data
add_action('acf/save_post', 'my_acf_save_post', 1);

The field “kontingent_text” is a text field.

However the field names returned are not the ones I enter in the field-editor.
They are some kind of key…If I print the $fields variable, I get this:

Array
(
[field_5516c5afed5e4] => Dies ist ein Kontingenttext!
)

The $field variable returns an undefined index error and only works if I insert field_5516c5afed5e4 as and index.

Is there any way I can use the regular field names?

Hi @philex

ACF uses the $field_key when submitting when submitting any form data so it may not be possible to use the $field_name

Ok, thanks for the information 🙂
