CodeIgniterで配列を設定ファイルから呼び出す

More than 1 year has passed since last update.

固定された内容の配列を、コントローラーやモデルのどこでも呼び出せる様に、config配下に設定する。たとえば、住所入力時の都道府県のリストなど。

CIのversion

CI_VERSION = '3.1.8';

config配下に都道府県の配列のファイルを置く。

application/config/prefectures.php

$config['prefectures'] = array(
    '1'=>'東京',
    '2'=>'神奈川'
);

autoloadを設定

application/config/autoload.php

$autoload['config'] = array('prefectures');

配列の呼び出し

どこのコントローラー、モデルからでも、以下で都道県の配列を取得できる。

$this->config->item('prefectures');
