Show select field label within nested repeater

Hello,

I have a nested repeater field (repeater inside another repeater) with a ‘select’ field inside that, and I basically just want to output the label for each item in the select field.

I have read the documentation, which shows the following:

$field = get_field_object('field_name');
$value = get_field('field_name');
$label = $field['choices'][ $value ];

However I can’t get this to work within a nested repeater. Is there a way around this?

For info, I am using ACF v3.5

Any help much appreciated
James

Hi @wickywills

The get_field_object function only works with parent fields. To find a sub field object, please use the get_sub_field_object function.

This function is documented below and was added in v4:
http://www.advancedcustomfields.com/resources/functions/get_sub_field_object/

Perhaps for now, you could use a work around like so:

<?php 

$field = get_field_object('repeater_field_name');

$sub_fields = $field['sub_fields'];

// debug variable to find the sub field key ($key)
echo '<pre>';
	print_r($sub_fields);
echo '</pre>';
die;

$sub_field = $sub_fields[ $key ];

?>

Hi @elliot,

Thank you for replying. I should point out that my PHP knowledge isn’t that great(!). I did however get the following output:

Array

                            [multiple] => 0
                            [order_no] => 1
                            [key] => field_51e9070105abe
                        )

                )

            [row_min] => 0
            [row_limit] =>

            [order_no] => 2
            [key] => field_51e6a6878509d
        )

)

What I basically want is to output the ‘choices’ array from the above. I’ve taken a look into multidimensional arrays and understand them (ish!), but not when they’re this deep. Do you know how I can output the ‘choices’?

Thanks again

Hi @wickywills

$sub_field = $sub_fields[ 'field_51e6a6878509d' ][ 'sub_fields' ][ 'field_51e9070105abe' ];

Ah I get it! Didn’t think it would be that easy 🙂

Thanks very much @elliot
