Tried multiple solutions. Still stuck on this.
I need to display different classes, based on the number of rows in a repeater field.
...
<?php elseif ( get_row_layout() == 'grid' ) : ?>
<?php if ( have_rows( 'grid_block' ) ) : ?>
<?php while ( have_rows( 'grid_block' ) ) : the_row(); ?>
// if total number of rows > 1 do this for all rows...
// elseif total number of rows > 2 do this for all rows...
// elseif total number of rows > 3 do this for all rows...
<?php endwhile; ?>
<?php endif; ?>
<?php endif; ?>
...
Thanks for any kind of help!
This will give you the number of rows
$count = count(get_field('grid_block'));
Thanks. I found that snippet before. It returns 0 in my case.
Not sure what I’m doing wrong:
...
<?php elseif ( get_row_layout() == 'grid' ) : ?>
<?php $count = count(get_field('grid_block')); ?>
<?php echo $count; ?> // No matter where I place this, it returns 0
<?php if ( have_rows( 'grid_block' ) ) : ?>
<?php while ( have_rows( 'grid_block' ) ) : the_row(); ?>
// if total number of rows > 1 do this for all rows...
// elseif total number of rows > 2 do this for all rows...
// elseif total number of rows > 3 do this for all rows...
<?php endwhile; ?>
<?php endif; ?>
<?php endif; ?>
...
Any thoughts on this?
Not sure how to solve this unfortunately.
Grid block is a sub field of another field, try 1 get_sub_field('grid_block')
So i’ve been using the syntax to get the count of a repeater’s rows from this thread successfully until I recently upgraded my PHP from 5 to 7. After upgrading to 7, I get the following warning:
Warning: count(): Parameter must be an array or an object that implements Countable in /nfs/c06/h08/mnt/153609/domains/mydomain.com/html/wp-content/themes/mytheme/template-name.php on line 135
The code in the template is as follows:
<?php $count = count(get_field("locations")); ?>
I then use the count in a conditional if/then statement.
It all still works, but throws the warning if php error reporting is on and I like to resolve it, but not sure how.
Actually, it shows even when error reporting is off. So i’ll have to fix it somehow
$count = 0;
$locations = get_field('locations');
if (is_array($locations)) {
$count = count($locations);
}
John,
Thanks again for your help. That fixed it!
