Hi,
I have a repeater called display_list and I want to output the checkbox categories I assign to to it like cat1,cat2,cat3…
I was expecting ' . $row['category'] . to do it but I just get the value “Array”. The field is set to show labels and the var_dump does show the values e.g.:

array(2) {
    [0]=>
    string(15) "Business Topics"
    [1]=>
    string(14) "General Topics"
  } <code>...from the</code>var_dump($row);

<?php
$rows = get_field(‘database_list’);
if($rows)
echo ‘<ul class=”db-list”>’;
{
$i = 0;
foreach($rows as $row)
echo ‘<li class=”Department” rel=”‘ . $row['category'] . ‘”><a href=”‘ . $row[‘link’] . ‘” target=”_blank”>’ . $row[‘title’] . ‘</a><a href=”anchor#” class=”addspeech” rel=”#’.$i.'”></a></li>’. PHP_EOL;
$i++;
var_dump($row);
}
}
echo ‘</ul>’;

?>

…how do I capture and output the values? Thanks

A checkbox field stores an array, to output the values you need to loop over that array,

I’m not sure why you’re using $rows = get_field(‘database_list’); instead of a have_rows() loop https://www.advancedcustomfields.com/resources/have_rows/

something like this, note this is not exact code, just an example.

if (have_rows('database_list')) {
  while (have_rows('database_list')) {
    $categories = get_sub_field('category');
    if ($categories) {
      // loop over catagories
      foreach ($categories as $category) {
        echo '<li>'.$category.'</li>';
      }
    }
  }
}

or using an array

$rows = get_field('database_list');
if ($rows) {
  foreach ($rows as $row) {
    if ($row['category']) {
      foreach ($row['category'] as $category) {
        echo '<li>'.$category.'</li>';
      }
    }
  }
}
