Attributes tag

[carstenjaksch]

I got this snippet for an Attribute tag somewhere:

class Attributes extends Tags
{
    public function index()
    {
        $except = $this->params->get('except', []);

        if (is_string($except)) {
            $except = explode('|', $except);
        }

        return collect($this->context->get('view', []))
            ->except($except)
            ->filter(fn ($value, $key) => Str::startsWith($key, ['data-', 'x-', '@', 'item']))
            ->map(fn ($value, $key) => $key . '="' . $value . '"')
            ->join(' ');
    }
}

That works great, but the big issue is that it renders the filtered attributes, if they are present on the parent too.

For example:

{{ partial:parent itemscope="" itemtype="https://schema.org/Review" }}
  {{ partial:child }}
{{ /partial:parent }}

{{# child partial #}}
<div {{ attributes }}>
</div>

Results in:

<div id="parentPartial" itemscope="" itemtype="https://schema.org/Review">
  <div itemscope="" itemtype="https://schema.org/Review">
  </div>
</div>

Is there a way to not render attributes from the parent?

As a workaround, I enhanced the Attributes filter with a keyword to unset the attributes on the child partial:

        return collect($this->context->get('view', []))
            ->except($except)
            ->filter(fn ($value, $key) => Str::startsWith($key, ['data-', 'x-', '@', 'item']) && $value !== 'unset') // filter keyword
            ->map(fn ($value, $key) => $key . '="' . $value . '"')
            ->join(' ');

{{ partial:child attribute="unset" }}
