  3. How do I add 5 or 10 items in repeater with one click?

I had tried following.

  • Make custom form widget and loop onAddItem function 5 times.
  • Add data-request="formMyJson::onAddItem;formMyJson::onAddItem;"
  • Create another dropdown with 1, 5 and 10 value. Set Repeater depensOn to it and try to set minItems option with filterFields.
  • Create trigger in dropdown and set minItems. Not work at all. Please advice.

You could just set the attribute to an empty array with 5 items in it ready to go

Thank you for your reply, @daftspunk.

May you explain more detail? Where I should set attribute?

Take a look at the documentation on accessors:

https://octobercms.com/docs/database/mutators#accessors-and-mutators

public function getMyRepeaterAttribute($value)
{
    // New records only
    if (!$this->exists) {
        return [... array with 5 items already in it ...];
    }
}

Please find following code. I want to click on balloon-selector and set repeater quantity. I used accessors for set and return JSON value. But after refresh with depensOn function. Repeater quantity still the same.

fields.yaml

    stamps_json:
        dependsOn: stamp_items
        minItems: 30
        maxItems: 100
        span: full
        type: repeater
        style: collapsed
        form:
            fields:
                active_icon:
                    label: 'Stamp Icon'
                    type: mediafinder
                    mode: image
                    default: /default/stamped.png
                inactive_icon:
                    label: 'Unstamp Icon'
                    type: mediafinder
                    mode: image

                    label: Point
