I don’t follow you. It’s a stretch beyond my comfort zone, I suppose.
I have this working (adapted from ACF website snippet):
<?php
$image = get_field('photo102');
if( !empty($image) ):
// vars
$url = $image['url'];
$title = $image['title'];
$alt = $image['alt'];
$caption = $image['caption'];
// thumbnail
$size = 'member-listing';
$thumb = $image['sizes'][ $size ];
$width = $image['sizes'][ $size . '-width' ];
$height = $image['sizes'][ $size . '-height' ];
if( $caption ): ?>
<div class="wp-caption">
<?php endif; ?>
<!-- see single-cdtxprofessional.php in this area for code for adding link to picture itself if you want that -->
<img src="<?php echo $thumb; ?>" alt="<?php echo $alt; ?>" width="<?php echo $width; ?>" height="<?php echo $height; ?>" />
</a>
<?php if( $caption ): ?>
<p class="wp-caption-text"><?php echo $caption; ?></p>
</div>
<?php endif; ?>
<?php endif; ?>
So, if the user doesn’t add an image here, I would like a default alternate. If I do the global ACF options method, I’m not clear on how I add the function with a priority less than 99. Also don’t know where I put such code, in theme functions or a plugin? Sorry, as I’m a bit green here.
