How to correctly implement custom php

General Questions

In my project, I have created a custom template where I showcase my previous projects. At the top of this template, there is a feature list where I state the features used within the project.

I have made each element editable using ACF but I know that the number of features used in each project will vary. I don’t want items in the list to be visible if they are not used. I went to the ACF documentation and found this for a basic implementation:

<?php if( get_field('field_name') ): ?>
    <p>My field value: <?php the_field('field_name'); ?></p>
<?php endif; ?>

And this for a loop:

<?php 

$fields = get_field_objects();

<?php if( $fields ): ?>
    <ul>
    <?php foreach( $fields as $field ): ?>

        <?php if( $field['value'] ): ?>
            <li><?php echo $field['label']; ?>: <?php echo $field['value']; ?></li>
        <?php endif; ?>

    <?php endforeach; ?>
    </ul>
<?php endif; ?>

My feature list structure looks like this:

<ul>
<li><span>strategy</span>
<li><span>strategy</span>
<li><span>strategy</span>
</ul>

Firstly, which of these is the correct one for my use case? And secondly, while conventionally, you would add this to the function.php file, what is the Pinegrow way to implement?

As it turns out, I simply have to not complete the field and it doesn’t show automatically :laughing:

However, the issue here is the implement of custom php. Using this example, it would be good to see how to input php correctly within Pinegrow.
