README

CompanyNumberField is a field for entering company registration numbers ("IČ" or "IČO" in Czech) into forms in ATK14 applications.

Installation

Just use the Composer:

cd path/to/your/atk14/project/
composer require atk14/company-number-field

Optionally you can symlink the CompanyNumberField file into your project:

ln -s ../../vendor/atk14/company-number-field/src/app/fields/company_number_field.php app/fields/company_number_field.php

Usage in an ATK14 application

CompanyNumberField 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("company_number", new CompanyNumberField([
      "label" => "Company registration number",
    ]));
    $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(!$this->form->fields["company_number"]->is_valid_for($d["country"],$d["company_number"],$err)){
        $this->form->set_error("company_number",$err);
        return;
      }

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

It's possible to set up CompanyNumberField 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("company_number", new CompanyNumberField([
      "label" => "Company registration number",
      "country" => "CZ"
    ]));
  }
}

Error message for invalid company_number 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("company_number", new CompanyNumberField([
      "error_messages" => [
        "invalid" => _("Invalid company number"),
      ],
      "format_hints" => [
        "CZ" => _("Please use format NNNNNNNN (8 digits)"),
        "LT" => _("Please use format NNNNNNNNN (9 digits)"),
      ],
    ]));
  }
}
