Difficulty sorting on repeater sub-field

I’ve looked through this page and *sort of* have things working, but just not quite.

It’s listing all objects, but only shows one <h2> for all of them. What am I missing? I need one grouping of <h2></h2>

for each sub_field titled ‘position’.

So, it would look something like:

<h2>Position 1</h2>

• Document #1 for position 1
• Document #2 for position 1
• Document #3 for position 1

<h2>Position 2</h2>

• Document #1 for position 2
• Document #2 for position 2
• Document #3 for position 2

This is my code thus far:

<?php // get repeater field data
$repeater = get_field('house_forms');

// vars
$order = array();

// populate order
foreach( $repeater as $i => $row ) {
    $order[ $i ] = $row['position'];
}

// multisort
array_multisort( $order, SORT_DESC, $repeater );

// loop through repeater
if( $repeater ): ?>
<h2><?php echo $row['position']; ?></h2>
<ul class="forms">

    <?php foreach( $repeater as $i => $row ): ?>
    <li class="form"><?php echo $row['form_name']; ?>
        <a href="<?php echo $row['document']; ?>" target="_blank">Download</a><?php if( $row['online'] ): ?> | <a href="<?php echo $row['online']; ?>">Fill out online</a><?php endif; ?>
    <?php endforeach; ?>

</ul>
<?php wp_reset_postdata(); ?>

Hi @brotsky_pixie

That’s because you put the code outside of the loop. It should be something like this:

// loop through repeater
if( $repeater ):

// initialize the position for later use
$position = '';
?>

<ul class="forms">

    <?php foreach( $repeater as $i => $row ): ?>
        
        
        <?php
        // check if the current postion is changed
        if( $position != $row['position'] ){
            
            // set the current position 
            $position = $row['position'];
            ?>
            
            <h2><?php echo $row['position']; ?></h2>
            
        <?php } ?>
        
        
        <li class="form"><?php echo $row['form_name']; ?>
        <a href="<?php echo $row['document']; ?>" target="_blank">Download</a><?php if( $row['online'] ): ?> | <a href="<?php echo $row['online']; ?>">Fill out online</a><?php endif; ?>
    <?php endforeach; ?>

</ul>
<?php wp_reset_postdata(); ?>

Because this is more related to PHP, kindly visit their community for further support.

I hope this helps 🙂

Ahhhhh…I see. Thank you. And I’m sorry I didn’t realize it was a purely PHP problem. I appreciate the help.
