Repeater Field in functions.php

I’m trying to populate an array through the repeater field however this is not related to the issue.

If i put the following code (from the documentation)

$rows = get_field('repeaterfieldname','option');

foreach($rows as $row)
	{
		echo '<li>sub_field_1 = ' . $row['field_name'] . ', sub_field_2 = ' . $row['field_description'] .', etc</li>';
	}

I get the following error Warning: Invalid argument supplied for foreach(), however if i put the same code into file header.php everything works, but i need that code to be in functions.php how can i fix this? Am i missing something ?

Is it within a loop? Don’t think get_field will work unless it’s within a loop?

Test it by doing print_r($rows) before foreach, see what you get

It doesn’t need to be in a loop. I found out the issue is related to this

since the repeater field i created is from an option not a custom field.

Hi @alexgold05

If your code is within the functions.php file, it need to run AFTER the init action.

Thanks
