Hi John,
That’s great. Your solution is all working for me now, there was another typo so here is the code again if anyone else is looking for a similar solution.
Thanks again for your help. Really appreciated.
Kind Regards
Paul
<?php
$group = 'burial_census_information';
$sub_fields = array(
'burial_1841_census',
'burial_1851_census',
'burial_1861_census',
'burial_1871_census',
'burial_1881_census',
'burial_1891_census',
'burial_1901_census',
'burial_1911_census',
'burial_1921_census',
'burial_1939_census'
);
$has_content = false;
foreach ($sub_fields as $sub_field) {
if (get_field($group.'_'.$sub_field)) {
$has_content = true;
${$sub_field} = get_field($group.'_'.$sub_field);
}
}
if ($has_content) {
?>
<div class="container-census-information burial-container">
<h2>Census Information this should only appear if there is content in any of the sub_fields</h2>
<?php
foreach ($sub_fields as $sub_field) {
if (!empty(${$sub_field})) {
?>
<h3><?php echo substr($sub_field, 7, 4); ?></h3>
<p><?php echo ${$sub_field}; ?></p>
<?php
}
}
?>
</div>
<?php
} ?>
Hi John, Thanks so much for your full and helpful answer, including the link to the variable variable documentation. Much appreciated. I think there may be an error on line 23 with the braces?
if ($has_content} {
Not sure if this should be:
if {$has_content} {
OR
if ($has_content) {
Many thanks
Paul
Hi ichabod,
Thanks for your comments. The code doesnt work because the group returns true when it has subfields even if they are empty. Im thinking I need to be using an array and checking that but I cant seem to get that to work either (my error im sure).
Yes this would probably work better as a repeater but I have lots of other groups and fields where that is not the case which will require the same solution so I need to figure this out.
Any help would be greatly appreciated.
Kind Regards
Paul
I am having the same issue on 5.8.11 with select fields returning an array when default value set but no value selected.
I should add, I meant the container div should only appear when a sub_field in a group has content. I can easily echo html with the sub_field content but havent worked out how to successfully add a container div around all of the content shown in the code snippet above. When adding any div html it shows regardless of whether the sub_fields do or do not have content.
Hope you can help. Bit confused. ta.
Paul
