Hello, I’m having trouble trying to get values from the last row of a repeater field. There is and always will be 4 rows.
I need to:
- get a text sub field
- if radio button value equals ‘x’…
- get image sub field (with thumbnail size)
- if url sub field, wrap image in a link
- if radio button equals ‘y’…
- get wysiwyg editor
I’ve read through and tried the examples in the documentation as well as some I found in the forum but I’m having a lot of trouble getting it right. Any tips are greatly appreciated.
Here’s where I’m at so far in my fumbling tests:
$rows = get_field('pods' ); // get all the rows
if( have_rows('pods') ):
while ( have_rows('pods') ) : the_row();
$rows = get_field('pods' ); // get all the rows
$first_row = $rows[3]; // get the last row
$first_row_image = $first_row['pod_image' ]; // get the sub field value
// Note
// $first_row_image = 123 (image ID)
$image = wp_get_attachment_image_src( $first_row_image, 'full' );
// url = $image[0];
// width = $image[1];
// height = $image[2];
?>
<img src="<?php echo $image[3]; ?>" />
<?php endwhile;
endif;
Hi @inhouse
This is a bit confusing… 😉
So you want to do these steps
get a text sub field
if radio button value equals ‘x’…
get image sub field (with thumbnail size)
if url sub field, wrap image in a link
if radio button equals ‘y’…
get oembed sub field
get wysiwyg editor
ONLY for the last row in your repeater?
Hi Jonathan, yes you understand my confusing question! I think if I had a couple of the listed items worked out for me I should be able to continue the logic to the remaining items. I don’t expect you to write it all out for me but any tips are much appreciated!
Okay 🙂
So to work with just the last row you can easily do something like:
<?php
$repeater = get_field('repeater');
$last_row = end($repeater);
echo $last_row['sub_field'];
?>
Thanks, that’s insanely easy compared to the documentation and other examples I found!
Admittedly this is more of a PHP issue than ACF so I’ll understand if this next question goes unanswered! One thing that’s tripping me up is using the advanced image vars. How do I use the $last_row variable in conjunction with the image title, alt, size vars? My attempt with ‘url’ was unsuccessful 🙂
if ( $last_row['pod_image'] ) {
$url = $last_row[ $pod_image['url'] ];
$title = $pod_image['title'];
$alt = $pod_image['alt'];
// thumbnail
$size = 'medium';
$thumb = $pod_image['sizes'][ $size ]; ?>
<img src="<?php echo $thumb; ?>" alt="<?php echo $alt; ?>" />
}
No problem!
You’re almost there. But notice that you try to use a variable $pod_image without first declaring it and setting its value.
<?php if ( $last_row['pod_image'] ) { ?>
<?php $pod_image = $last_row['pod_image']; ?>
<img src="<?php echo $pod_image['sizes']['medium']; ?>" alt="<?php echo $pod_image['alt']; ?>" />
<?php } ?>
And I overcomplicated things yet again. This works great and makes perfect sense! Thanks so much for your help Jonathan! Above and beyond fantastic support!
No problem 🙂 Overcomplicating things tend to happen in code! That’s why a lot of developers try to refactor their code while developing!
Have a nice weekend
When using this with a repeater that is IN a Flexible Content field.. I get this error:
Warning: count(): Parameter must be an array or an object that implements
@revive Did you ever get this figured out?
I’m using a repeater inside a flexible field too and I’m getting array errors with the ‘end’ code.

Sorry, I don’t recall what project this issue came up in, so I don’t have a solution at hand for it.
