Counting in panel

Kirby 2 Solved ✅
1

I use a structured field for listing reservations: name, email, ticket amount.
I would like to see in the panel the total amount of all the reservations combined. So how do I count all the ticket amounts in the panel? It only has to be visible in the panel. How should I approach this?

You’d have to create a custom field to display that information.

Ok, so then the counting logic is written in the custom field?

And the read the data from the structured field. Does that work the same way is it would on a template?

Might make more sense to make a dashboard widget if its just a count up you want.

If you base it on the info field, it can be. as basic as this:

<?php

class TestField extends InfoField
{



  public function result() {
    return null;
  }

  public function element() {
    $element = parent::element();
    $element->addClass('field-with-icon');
    return $element;
  }

  public function input() {
    return '<div class="text"> The Structure Field X contains ' . $this->page()->fieldname()->toStructure()->count() . ' items</div>';
  }
}

If you want to make it more versatile, instead of hardcoding the name of the structure field, you could add it as an attribute of the field.

<?php

class TestField extends InfoField
{

  public $fieldname;

  public function result() {
    return null;
  }

  public function element() {
    $element = parent::element();
    $element->addClass('field-with-icon');
    return $element;
  }

  public function input() {
    return '<div class="text"> The Structure Field '.$this->fieldname.' contains '.$this->page()->{$this->fieldname}()->toStructure()->count().' items</div>';
  }
}

In your blueprint:

fields:
  test:
    label: No of items
    type: test
    fieldname: contactoptions

A widget makes sense if you don’t want to display it in the page itself but on the dashboard.

Ah yes, that makes a lot of sense.

After some fiddling, it works!
Thanks a lot!
