Dynamic injected value doesn't work after upgrading to 3.3.4

[bruceontheloose]

After upgrading from 3.2.37 to 3.3.4, I'm experiencing an error with an injected value. So you know, I didn't opt in to the new Antlers parser.

Here's the relevant bit from our collection's config:

inject:
  title_as_month_day: '{{title insert="2020-|0" format="F j"}}'

Entry titles in this collection are in the form of mm-dd, so for the entry with title: 10-02, the injected title_as_month_day would have a value of "October 2," which we render in various spots in the page.

That all worked fine prior to upgrading. But now title_as_month_day renders as {{title insert="2020-|0" format="F j"}}. To test whether insert or format were part of the issue, I tried injecting title_as_month_day: '{{title}}'. I got a similar result: title_as_month_day rendered as {{title}} instead of the value.

In case you're curious, the same problem occurs with the new Antlers parser enabled.

Is there a solution you're aware of or should I file this as a bug?

Thanks.

I wouldn't have thought you could put Antlers in injected variables like that in the first place. I'm surprised it ever worked.

I'd suggest removing that variable and making a tag instead.

<?php

namespace App\Tags;

use Carbon\Carbon;
use Statamic\Tags\Tags;

class TitleAsMonthDay extends Tags
{
    public function index()
    {
        $title = '2020-'.$this->context->get('title');
        return Carbon::parse($title)->format('F j');
    }
}

Thanks so much, @jasonvarga! I really appreciate it.

I was new to creating custom tags, so here are the steps I took to implement Jason's code, for anyone who may land here and find them useful. (Docs page for reference: Building Tags.)

1. Ran php please make:tag TitleAsMonthDay, which added the stub file, /app/Tags/TitleAsMonthDay.php.
2. Replaced all the starter code in TitleAsMonthDay.php with Jason's code.

From there, you can use the tag in a template with {{ title_as_month_day }}. (As the docs say, "the tag’s “handle”...will be the snake_cased version of the class name by default.") In our case, I'm passing it into a partial, similar to:

{{ 
  partial:example_partial 
    example_date_text="{title_as_month_day}"
}}

Thanks, again!
