Hello,
I’m using ACF Gallery add-on to display galleries on my website, so far it worked perfectly.
Now my client wants to display only a small preview of the gallery, only four images and then all the rest. In other words I need to split the gallery in two parts.
Getting the first 4 images is not a problem, I’m just outputting each one of them using <?php echo $images[x]['url']; ?>. It’s not the most elegant solution, but it works.
I know that there is no “offset” parameter to use (but please, consider it a feature request), so I was wandering if there’s a way to exclude the first 4 images from the array generated by <?php $myimages = get_field('image_gallery'); ?>
I’m not a php expert, so there’s probably a better approach to this problem. Any suggestion would be much appreciate.
The best way to remove them is to just remove them from the beginning of the array
$myimages = get_field('image_gallery');
for ($i=0; $i<4; $i++) {
// make sure there's still something in the array
// I don't know if array_shift will cause an error on an empty array
if (!empty($my_images)) {
$remove = array_shift($myimages);
}
}
print_r($myimages);
Also, you can do something similar to truncate the array to the first 4
$myimages = get_field('image_gallery');
while (count($myimages) > 4) {
$remove = array_pop($myimages);
}
print_r($myimages);
John – great tips. I’d suggest adding either/both snippets to the documentation, as it seems like a pretty common use case; I was looking to do the same and wouldn’t have found it without some digging!
