I’m having trouble displaying my add-more data (in my first attempt to use and display them), and in reading the support article on doing this:

https://piklist.com/user-guide/docs/field-parameters/add_more/

…I find I have more questions than answers. Here’s the key questions that have come up as I read it:

Under “Basic add-more”, the first example of code to grab the data is:

// Get field data
$exercise = get_post_meta($post->ID, 'exercise', true);
 
// Get your custom template part: addmore-workout-template.php
piklist($path_to_template . '/addmore-workout-template', array('data' => $exercise, 'loop' => 'data'));

With the first line commented as “get field data”.

I’m comparing this to how I’ve previously captured (non-repeating) metafields, i.e.:

// Capture all the metadata in $data
$data = get_post_custom($post->ID);

// Display a field
echo $data [recipe_description][0];

Doesn’t the first line here grab all my metafields for the post? Does it ignore add-more fields? Do I use the previous code example only for add-more metafields in particular?

I also presume that the reference to $path_to_template is not an actual variable but just a placeholder for the methods described farther down – different code depending on whether we’re working in a plugin or a theme.

The sample code for pulling advanced (i.e. nested) add-more metadata into a theme looks like this:

// Get the post meta information
$workout_schedule = get_post_meta($post->ID, 'workout_schedule', true);
 
// 1. Display the data using the file workout_schedule_template.php.
// 2. Assign your $workout_schedule parameter (from above) to 'data'.
// 3. Loop through 'data'.
piklist($path_to_template . '/workout_schedule_template', array('data' => $workout_schedule, 'loop' => 'data’));

Here, the comment on the first code line is a little different even though its structure is the same. It says “Get the post meta information”, not “Get field data”. But as I understand it, this code is specifically targetting just specific Group field data, is that correct?

Finally, I’m working in a child theme, so wouldn’t my “$path_to_template” code be:

piklist(get_stylesheet_directory_uri() . '/addmore-workout-template', array('data' => $exercise, 'loop' => 'data’));

not

piklist(get_stylesheet_directory() . '/addmore-workout-template', array('data' => $exercise, 'loop' => 'data'));

?

(The “_uri” is required, as I understand it, when referring to paths within child themes…)

Possibly my questions simply relate to how this info is being presented but I am finding it tough going sorting this out. I’m continuing to experiment, but I do hope you can help/advise on these questions.

Thanks!
