I get this error to log every time I try to add a new portfolio project page (Modena theme):
Exception Occurred: /var/www/clients/client106/web2312/web/concrete/blocks/image_slider/form_setup_html.php:74 Undefined variable $navigationType (2)
It should open a new page to Composer but I get a blank page.
On this site I use core 9.3.9 with PHP 8.1.9
I tested this on the other 9.3.9 site (Modena) with PHP 7.4.3 and it works.
Could this be PHP 8 bug?
This error message indicates that the variable $navigationType is being referenced in form_setup_html.php on line 74, but it has not been defined or initialized. This is because of the way php 8+ deals with variables.
You just need to put something like
$navigationType ??= '';
In the file or look to see if there is a default value like arrows or bullets and then put that
$navigationType ??= 'arrows';
Line 74:
<?php echo $form->radio($view->field('navigationType'), 0, $navigationType, ["id" => "navigationTypeArrows", "name" => $view->field('navigationType')]); ?>How do you think I can change this line?
<?php
echo $form->radio(
$view->field('navigationType'),
0,
$navigationType??'', // **CHANGE HERE**
[
"id" => "navigationTypeArrows",
"name" => $view->field('navigationType')
]
);
?>
Formatting above is not important, its just to clarify the fix.
Pinging @VidalThemes as the developer of this package.
Tried this change. Adding page tries to open Composer (spinning icon) but opens still blank page.
From console I can see there is this warning:
Failed to load resource: the server responded with a status of 500 (Internal Server Error)

“Undefined variable $navigationType”
The radio button is part of a set of similar buttons. You need to make the same change to the code for the other buttons in the set.
you can just add the change higher up the page
<div>
<button type="button"
class="btn btn-success ccm-add-image-slider-entry ccm-add-image-slider-entry-<?php echo $bID; ?>">
<?php echo t('Add Slide'); ?>
</button>
</div>
</div>
</div>
<?php $navigationType??'', // **CHANGE HERE** ?>
<div class="tab-pane" id="options-<?php echo $id; ?>" role="tabpanel">
<div class="form-group">
<?php echo $form->label("", t("Navigation")); ?>
<div class="form-check">
<?php echo $form->radio($view->field('navigationType'), 0, $navigationType??'', ["id" => "navigationTypeArrows", "name" => $view->field('navigationType')]); ?>
<?php echo $form->label("navigationTypeArrows", t("Arrows"), ["class" => "form-check-label"]); ?>
</div>
<div class="form-check">
<?php echo $form->radio($view->field('navigationType'), 1, $navigationType, ["id" => "navigationTypeBullets", "name" => $view->field('navigationType')]); ?>
<?php echo $form->label("navigationTypeBullets", t("Bullets"), ["class" => "form-check-label"]); ?>
</div>
<div class="form-check">
<?php echo $form->radio($view->field('navigationType'), 2, $navigationType, ["id" => "navigationTypeArrowsAndBullets", "name" => $view->field('navigationType')]); ?>
<?php echo $form->label("navigationTypeArrowsAndBullets", t("Arrows & Bullets"), ["class" => "form-check-label"]); ?>
</div>
I tried also with ; after ‘arrows’ and no space before ??= but no change.
Try my code above
<?php $navigationType ??= ''; // **CHANGE HERE** ?>
put that in
If you’re getting an “unexpected ?” error when using ??=, it likely means you’re on an older PHP version (below PHP 7.4) or there’s a syntax issue.
try
$navigationType = $navigationType ?? '';
I get this argument now:
“syntax error, unexpected token “;”, expecting “)””
# PHP Version
8.1.9
Can you copy the code here so we can review?
Yes of course.

Now we have fixed line 74 but we have syntax error, unexpected token “<”, expecting end of file on line 72:
On line 70 you have this
<?php $navigationType ??= ''; // **CHANGE HERE** ?>
Change it to this
<?php $navigationType ??= ''; ?>
The php comments // were hiding the php closing tag from being read by the browser, basically when you add these comments // anything after those on the same line will be hidden.
If the closing tag had been moved to the next line down the error would not have occured.
Like this:
<?php $navigationType ??= ''; // **CHANGE HERE**
?>
Now the code change is perfect and I can successfully add a Portfolio project page. Thank you all a lot.
