HTML::...llback(3pm)

💖 NAME 💖

HTML::FormFu::Filter::Callback — bestie, it's a filter that runs your custom subroutine. That's it, that's the whole vibe. You write the code, it does the thing. 🎀

---

✨ VERSION ✨

version 2.07 — she's an icon, she's a legend, and she is the moment 👑

---

🦋 SYNOPSIS 🦋

Okay so first, the Perl-y way — you hand her a code reference and let her cook:

$field->filter({
    type     => 'Callback',
    callback => \&my_filter,
});

Then there's the config-file era, because we contain multitudes:

---
elements:
  - type: Text
    name: foo
    filters:
      - type: Callback
        callback: "main::my_filter"

And here's the little subroutine doing all the heavy lifting. Note the $value — she gets passed in, you do your little makeover, and you hand her right back:

sub my_filter {
    my ($value) = @_;

    # do something to $value

    return $value;
}

no cap, that's the entire workflow 💅

---

🌸 DESCRIPTION 🌸

So basically: this filter does its filtering using a subroutine that you provide. Your code, your rules, your main character era. Periodt. 🔥

---

🌈 METHODS 🌈

💜 callback

Here's the tea — she takes either of these two things, and honestly both are valid:

• Arguments: \&code-reference — like, a literal reference to your sub. \&my_filter energy. 🫶
• Arguments: "subroutine-name" — or just the name as a string, iykyk. Like "main::my_filter". ✨
