Drop Down Selector

[humburger2015]

I have a dropdown selector for languages. It was creating using the custom fields in WordPress. There will be some fields that i need to leave blank but the blank fields still show up in the drop down selector. Is there a PHP "if" statement that someone can supply me that would hide blank fields in the drop down. For example, 'if' character count is less than 1 then hide field?

Here is the code I currently have:

<!-- Countries Select Box -->
        <select id="country_selector">
          <?php foreach ($footer["countries"] as $country) : ?>
            <option value="<?= $country['english'];?>" data-int-url="<?= $country['url'];?>" data-int-img="<?= $country['img'];?>" data-int-cc="<?= $country['cc'];?>">
              <?= $country['native'];?>
            </option>
          <?php endforeach; ?>
        </select>

Yes. Look using empty as the condition for the if.

 

Although a better alternative would be to modify your query so it does not return values which are empty.

Thank you, Ch0cu3r. Would you be able to show me how the empty condition would be applied to this code?

I assume its the native value you want to check is not empty?

<?php
foreach ($footer["countries"] as $country):
	if(!empty($country['native'])):
?>
<option value="<?= $country['english'];?>" data-int-url="<?= $country['url'];?>" data-int-img="<?= $country['img'];?>" data-int-cc="<?= $country['cc'];?>">
  <?= $country['native'];?>
</option>
<?php 
	endif;
endforeach;
?>

Worked perfectly. Thank you so much!
