Get all Fields and Subfields from a page (pageID)

Hi everybody,

I’m looking for a way to gather all fields of a page (field, repeaterfields, their repeaterfields and so on and so on … ) into one array, either as objects or data-arrays with “name” and “value”.

All I know going into this is the pageId. I dont know any “names” or content of any subfields, infact, “names” and “values” is what Im looking for.

While get_field_objects() and get_fields() will do the trick for firstlevel fields, repeater fields will be returned as an array, and by trying to somehow collect them via key or anything I keep failing and failing and after two days I’m pretty much spent -_____- …

Is there any way, a simple loop function or anything that could do that? I need a function that I only feed with the pageID and that returns an array of its fields and subfields. And I just kinda cant shake this feeling that this should be rather simple and easy, and that I’m just missing something, but Im simply out of ideas :-S

Any help would be much appreciated! Thanks in advance,
ANB_Seth

acf get_fields() does get the field names and values of repeaters and flex fields. For Example it returns this for a repeater

[repeater] => Array
        (
            [0] => Array
                (
                    [field_1] => value 1
                    [field_2] => value 2
                )

            [1] => Array
                (
                    [field_1] => value 1
                    [field_2] => value 2
                )

        )

Each sub array represents a row and the values are in field name => value pairs just like the top level fields.

A flex field is returned like this

[flex] => Array
        (
            [0] => Array
                (
                    [acf_fc_layout] => layout_1
                    [field_1] => value 1
                    [field_2] => value 2
                )

            [1] => Array
                (
                    [acf_fc_layout] => layout_2
                    [field_1] => value 1
                    [field_2] => value 2
                )

        )

again, of the values of the array is a row of the flex field.

maybe I’m missing what it is you’re really looking for. I think the real difficulty will be in telling the difference between flex fields, repeaters and other field types that store array values like select and checkbox fields.

first up, thanks for the response 🙂 … I’ll try around with it. As for “what im really looking for”, im trying to create an array that holds all data from every field within a page, be it normal or repeaterfields (or repeaterfields within repeaterfields etc.). So in the end the mentioned array should be full of either fieldobjects, that I could extract data from (“name”, “value”, “type” etc.), or little arrays that hold this data, like [“thefieldname”, “thefieldvalue”, “thefieldtype”].

So Im kinda trying to fill a function like this:

function getAllFields($pageID) {
$everyFieldData = array();
…
…
(push fields or [name,value,type] of every field/subfield in $everyFieldData)
…
…
return ($everyFieldData);
}

How would I possibly approach or fill a function like that?

Do you mean get_field_objects ?

$fields = get_field_objects( $post->ID );

well, no … or kinda. I did try “get_field_objects” (first thing I tried) but trying out the gathered field-objects (“name” and “value”), those objects with repeaterfields only returns arrays for “value”, and I dont know how to further break this value-arrays apart, since those could contain arrays themself and so on.

I just need every field of a page gathered, be it normal or subfield, and put into one array. So … pretty much the function I described a bit further up … but filled and working XD. Yet I’m starting to think getting this to work will not be as easy as I had hoped :-S ^^

Okay, so I have worked myself to this functons which seem to do the trick:

function abGetAllFields($pro_num){
	$tmpArr = get_field_objects($pro_num);
	$fillArray = array();
	foreach( $tmpArr as $tmpFieldObject ) {
		$fillArray = abGetAllFieldsCycle($fillArray, $tmpFieldObject["name"], $tmpFieldObject["value"]);
	}
	return $fillArray;
}

function abGetAllFieldsCycle($fillArray, $name, $value) {
	if (is_array($value)) {
		foreach( $value as $key => $value ) {
			$fillArray = abGetAllFieldsCycle($fillArray, $key, $value);
		}
	} else {
		array_push($fillArray, [$name, $value]);
	}
	return $fillArray;
}

$myFieldArray = abGetAllFields($pageId);
