HTML::...allback(3pm)

💖 NAME 💖

HTML::FormFu::Transformer::Callback — a Callback transformer, bestie. That's the whole vibe. 🎀

Oh and btw, the manual page itself shows up as HTML::...allback(3pm) in the header and footer, that's just how it's filed, don't stress. 🦋

✨ VERSION ✨

version 2.07 — iconic, current, no notes. 👑

🌸 SYNOPSIS 🌸

okay so here's how you actually use it, look:

    $field->transformer('Callback')->callback( \&my_transformer );

    ---
    elements:
      - type: Text
        name: foo
        transformers:
          - type: Callback
            callback: "main::my_transformer"

two ways to serve the same lewk: hand it a code ref in Perl, or name the sub in your config. slay. 💅

---

💜 DESCRIPTION 💜

so when your callback gets called, it gets two things handed to it, and you need to know what they are, fr fr:

• first argument = the submitted value for the associated field. like, the actual thing the user typed in. 🍓
• second argument = a hashref of name/value pairs for all the input fields. yes, all of them, the whole roster. 🌈

that's it, that's the tea. 🫶

🧚 METHODS 🧚

callback

Arguments: \&code-reference

Arguments: "subroutine-name"

so you can pass it either a straight-up code reference (\&code-reference) or just the name of the subroutine as a string ("subroutine-name"). both valid, both cute, pick your fighter. 😭✨

💀 SEE ALSO 💀

• Is a sub-class of, and inherits methods from HTML::FormFu::Transformer — so all the inherited goodness comes along for free, periodt.
