README

ZipField is a field for entering postal codes into forms in ATK14 applications.

Installation

Just use the Composer:

cd path/to/your/atk14/project/
composer require atk14/zip-field

Optionally you can symlink the ZipField file into your project:

ln -s ../../vendor/atk14/zip-field/src/app/fields/zip_field.php app/fields/zip_field.php

Usage in an ATK14 application

ZipField has method is_valid_for() for re-validation in context of the selected country.

In a form:

<?php
// file: app/forms/users/create_new_form.php
class CreateNewForm extends ApplicationForm {

  function set_up(){
    // ...
    $this->add_field("zip", new ZipField([
      "label" => "ZIP Code",
    ]));
    $this->add_field("country",new ChoiceField([
      "label" => "Country",
      "choices" => [
        "CZ" => "Czech Republic",
        "SK" => "Slovakia",
        "AT" => "Austria",
        "PL" => "Poland",
        // ...
      ],
    ]));
  }
}

In a controller:

<?php
// file: app/controllers/users_controller.php
class UsersController extends ApplicationController {

  function create_new(){
    // ...
    if($this->request->post() && ($d = $this->form->validate($this->params))){
      // postal code re-validation for the selected country
      if(!$this->form->fields["zip"]->is_valid_for($d["country"],$d["zip"],$err)){
        $this->form->set_error("zip",$err);
        return;
      }

      $user = User::CreateNewRecord($d);
      // ...
    }
  }
}

It's possible to set up ZipField only to accept postal codes from one specific country. Re-validation is not necessary in this case.

<?php
// file: app/forms/users/create_new_form.php
class CreateNewForm extends ApplicationForm {

  function set_up(){
    // ...
    $this->add_field("zip", new ZipField([
      "label" => "ZIP Code",
      "country" => "CZ"
    ]));
  }
}

Error message for invalid zip code or format hints can be specified

<?php
// file: app/forms/users/create_new_form.php
class CreateNewForm extends ApplicationForm {

  function set_up(){
    // ...
    $this->add_field("zip", new ZipField([
      "error_messages" => [
        "invalid" => _("Invalid ZIP code"),
      ],
      "format_hints" => [
        "CZ" => _("Please use format NNN NN"),
        "AT" => _("Please use format NNNN"),
      ],
    ]));
  }
}
