Kirby Builder: Call to a member function _key() on string

Kirby 3 Solved ✅
1

Hi Community,

we are a small digital agency and are trying to build our new website with kirby. currently we are using the kirby page builder to be flexible with content elements. i hope this is the right approach.
now we just have a problem, which is only on the remote server. in the local development environment it works without problems.
in the default template we have the following code to retrieve the content from the page builder:

<?php
        foreach($page->mybuilder()->toBuilderBlocks() as $block):
            snippet('blocks/' . $block->_key(), array('data' => $block));
        endforeach;
   ?>

This error message is shown:

Call to a member function _key() on string

We have 5 Block Snippets. if necessary, I will post them as well.
Could anyone help please? Thanks!

Could you post the blueprint, please?

It’s probably an issue with the field name or stuff not being readable. Does the rest of the content render correctly?

Welcome to our community!

$block in the above returns null in this case, for whatever reason. To verify, change that code snippet to:

<?php
        foreach($page->mybuilder()->toBuilderBlocks() as $block):
           dump($block);
        endforeach;
?>

Does the template spit out the title (after you changed the code)? Or nothing at all apart from header and footer.

Do you happen to use uppercase in file names anywhere?

Please also check file and folder permissions and ownership on the server.

if i change the code to your snippet an array of my content is shown, Kirby\Cms\StructureObject Object. does that mean anything to you?

i have no uppercase filenames.

my development environment looks like this:
I develop locally,
push into git repository
my Webserver (with plesk) pulls the content from git automatically

files have 644
folders 755

I’m sorry,
i just saw that the output with your sippet on my local machine starts like this:

Kirby\Cms\StructureObject Object
(
    [content:protected] => Array
        (
            [sectionfields] => Array

                    [0] => Array
                        (
                            [text] => rem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa.

                            [_uid] => bodytext_1600095607596_715
                        )

                    [1] => Array
                        (
                            [image] => Array

and remote so:

is there anything missing because it starts completly different?

Is that really the snippet that is causing the error? I noticed you are using a nested builder field…

The content looks ok to me.

i am not sure. on my local machine everything works, on the computer of an employee and on the remote web-server it causes this error.

Oh, I didn’t read clossly, so on the remote server, the output is really that string instead of the structure object.

Is the page builder plugin actually present on the server? If it was, then you should see the same as on the local server.

Maybe you added the plugin as a submodule and did not initialize it on the server?

10

oh no! the plugin folder is completly missing! :woozy_face:
how could this happen? there is no entry in the gitignore file.

11

As I wrote above, if you have a git submodule workflow or using composer, then it’s probably not in your repo and doesn’t get deployed.
