You could try just using the built in foreach loop that starts on line 83 of default.php in the split content override
<?php foreach ($item->extra_fields as $extraField): ?>
<li class="type<?php echo ucfirst($extraField->type); ?> group<?php echo $extraField->group; ?>">
<span class="moduleItemExtraFieldsLabel"><b><?php echo $extraField->name; ?></b></span>
<span class="moduleItemExtraFieldsValue"><?php echo $extraField->value; ?></span>
<br class="clr" />
</li>
<?php endforeach; ?>

and insert a condition to only print out the extra field you want

Code that works in the split content override below. You can also use the | (or) if you want to show more than one extra field and can specify it by name

William,

thank you very much this is exactly what I wanted to achieve.

I don't know php yet, but I want to learn it very much.

Thank you for providing code I needed !

Thanks so much for posting the foreach loop. I think this gets me on the right track.

What does the php code look like to insert a condition to print out a specific field?

Thanks! -- Steven
