If you really want to allow pasting all of the items at once, or this was a requirement by the client, using what is available I would choose a textarea field and I would include instructions about putting each ingredient on a new line. Very similar to how the choice settings for radio, checkbox and select fields work in ACF. I would set the formatting of the text field to “No Formatting”. I would then parse the value of the field either by getting the value and parsing it or I’d build an acf/format value filter that would do the formatting so I don’t have to re-code the parsing or call a function.
add_filter ('acf/format_value/name=my_field_name', 'format_my_field_name', 20, 3);
function format_my_field_name($value, $post_id, $field) {
if (!$value) {
return $value;
}
$array = acf_decode_choices($value);
if (!is_array($array) || empty($array)) {
return $value;
}
ob_start();
?>
<ul>
<?php
foreach ($array as $line) {
?><li><?php echo $line; ?></li><?php
}
?>
</ul>
<?php
$value = ob_get_clean();
return $value;
}
