How to get the sub-field key names

Hi, I’d like to be able to get at the unique meta-key name for a sub field within a flexible content area (or a repeater).

Ideally what I’d like to do is call get_sub_field_object() and have returned in the array the meta_key name that corresponds to the unique custom field name (i.e. “custom_content_1_content”) but can’t figure out how to do it.

I’d eventually like to do something like this so that I can pass the name of the custom field to another plugin to update:

<?php 
$col = get_sub_field_object("left_column"); 
$colKey = $col["unique-key"];
?>

<div class="custom" id="col1" pid="<?php echo $page_id; ?>" custom-field-name="<?php echo $colKey; ?>">
  <?php the_sub_field("left_column"); ?>
</div >

Any help you can give would be very welcome.

Thanks,
Gregor

Hi @gspowart

There is no function to retrieve the actual postmeta meta_name value.
However, you can use some simple logic to find it.

The pattern to find the meta_name is:
$parentName_$rowIndex_$childName

If you know the parent field name and the child field name, this is a simple task. You can find the row index by using a counter in your loop.

Feel free to paste up any code you are having trouble with it.

Thanks
