Radio Buttons and Repeater fields….

Okay guys, have what hopefully should be a simple thing to do but I cannot for the life of me figure this out….

I have a set of repeater fields, one of the repeater fields is a radio button with choices of “left, right, center.”

What I want to do, is have is so that a user chooses the radio button, and on the front end it just applies whatever the value is to a class… like this: <h2 class=”left”> (left would be the choice they user put, and it literally just puts that as the class name. I would then just apply a style for “align left”, etc.

However, I cant get ANY value from the radio button to appear on the page, even though I have other advanced custom fields that appear on the page correctly… here’s what I am trying to do… can someone please help steer me in the right direction? “imagealigned” and “titlealigned” is the name of the custom field. Headline works, which is just text a user puts in…

<?php if( have_rows(‘rowtop’) ): ?>

<?php while( have_rows(‘rowtop’) ): the_row();

echo ‘<div class=”rowtop”>’;
echo ‘<main id=”main” role=”main” class=”container m-t-lg m-b-lg”>’;

// vars
$headline = get_sub_field (‘headline’);
$titlealigned = get_sub_field(‘titlealigned’);
$imagealigned = get_sub_field(‘imagealigned’);

?>

<?php if( $headline ): ?>

<?php
echo ‘<h2 class=”‘. $titlealigned.'”>’;// display a sub field value
the_sub_field(‘headline’);

echo ‘</h2>’;

?>

<?php endif; ?>

<?php if( $image ): ?>

<?php
echo ‘<img class=”‘. $imagealigned.'” src=”‘;// display a sub field value
the_sub_field(‘image’);
echo ‘/>’;

?>

<?php endif; ?>

<?php $image = get_sub_field(‘image’);
//Checking if anything exists for the image field
if ($image) { ?>
<?php echo ‘<img src=”‘;// display a sub field value
the_sub_field(‘image’);
echo ‘/>’;
?>
<?php } //if there is nothing for image then display
else { ?>
<?php }
?>

<?php echo $content; ?>

<?php
echo ‘</main>’;

echo ‘</div>’;
?>

<?php endwhile; ?>

<?php endif; ?>

</div>

What do you get if you echo out the values right after getting them?

// vars
$headline = get_sub_field (‘headline’);
$titlealigned = get_sub_field(‘titlealigned’);
$imagealigned = get_sub_field(‘imagealigned’);

// what values are being returned?
echo $titlealigned,':',$imagealigned;

Thanks for the reply, hmm I still get the same result – nothing on the front end displays at all. Example, it shows <h2 class></h2>

I think the issue is that it just does not display the values of “left” “right” or “center.” Does something else have to happen for those to appear?

A radio field stores a single text value. There are a couple of reasons that it might not return anything; using the wrong field name, no value selected, no values to select, trying to get the field in the wrong context. There might be some other reasons but nothing I can figure out without also seeing the field group. Can you export the field group put it in a .zip file and attach it? Maybe I can figure it out by looking at that.
