Hi, thank you for this,
It works much as the second and third options do already – that is – as long as it’s not wrapped in a hyperlink it shows only on those introductions that have a worksheet. Once I wrap the if statement with href:
<a href="<?php if(get_field('worksheet_link')){the_field('worksheet_link');} ?>">Go to Worksheet</a>
…it appears on all the introductions again.
Any other ideas?
