Loop $page fields but not all

[sicnarf]

Hello,

I found this code which iterates all fields of the page. How could I make it to NOT include some fields?

<?php foreach( $page->content()->fields() as $f ): ?>
  <?= $page->$f() ?> <br />
<?php endforeach ?>

Thanks.

Like this:

$fields = $page->content()->fields();
unset($fields['text']);
foreach ($fields as $field) {
  echo $field;
}

Note that it is enough to echo $field you don’t have to call $page->{$field}() again, since $field is a field object.

Downside of this approach is that you don’t know the type of field and hence not the right field method to render its content (html(), kt()etc.):

unset($fields[‘text’]);

This doesn’t seem to accept multiple fields. This gives me a syntax error.

unset($fields['title', 'price', 'description', 'cover', 'thumbnail']);

With regards to the fields I want to loop through, they are all type: text.
This is just a matter of cleaning the code because I am using Tailwindcss and its a mess to style 30 lines of <li>.

unset($fields['title'], $fields['price'], $fields['description'],$fields['cover'],$fields['thumbnail']);

Or get the keys from the $fields array and then do an array_diff.

Alright, this works but the uploaded images are being included.

This is my .yml

images:
    label: Images
    icon: image
    sections:
      images:
        headline: Images
        type: files
        template: image
        layout: cards
        image:
          cover: true

I tried to add $fields['images'] but it doesn’t work.

[texnixe]

images is not a field, it can’t possibly be in the content file and so you can’t unset() it.

I don’t really understand the problem.

@texnixe

images is not a field, it can’t possibly be in the content file. Are you getting the fields from the blueprint instead of from the content file?

This is being echoed in the loop. And this is the original filename of the image. I have already removed the cover, thumbnail fields which has different generated names.

Edit:
Wait, what do you mean by this?

@texnixe

Are you getting the fields from the blueprint instead of from the content file?

[texnixe]

I can’t possibly know where it comes from, maybe an image included in a text field?

[sicnarf]

Well, yeah it’s from the old blueprint . It’s indeed on the .txt file.

Thank you.

Here’s a little script if you want to clean up your text files:

Plugin 'k3-image-clip': Illegal string offset 'id'

Ok, here’s a recipe how to clean up your site: Don’t forget to make a backup before running this code. Also, you might not want to run through the complete index if you have thousands of pages.

Pardon my knowledge but how can I run this?
I tried putting it a new php file in the root folder. Opened up http://site.test/clean.php but I think it’s not working. I’ve checked my edited text file and it wasn’t cleaned up.

If you want to run it from the root folder, you have to include the bootstrap file and define the $kirby and $site variables (require __DIR__ . '/kirby/bootstrap.php';)

However, you can also put it into any template, eg. the home.php template to make your life easier.

Don’t forget to make a backup first.
