CodeIgniterでダウンロード可能なリンクとしてアップロードしたファイル（PDF、DOCなど）を表示する方法

Question

私はCodeIgniterが新しくなっていますが、私は何かを把握できます。 ユーザー登録時にアップロードされたファイル（pdfおよびdoc）を管理者に表示またはダウンロードさせたいという問題に直面しています。 すべてうまくいっていますが、管理者がファイル名を見るだけでなく、ファイルをダウンロードしてもらいたいです。ここ

は私のコントローラである。

ありがとう： https://www.codeigniter.com/user_guide/helpers/url_helper.html#base_url

あなたがこのようなURLヘルパーをインポートすることができます。

$this->load->helper('url'); 

その後、あなたは方法のBASE_URL

<a href="<?= base_url('path/to/directory/' . $row['supporting_documents']); ?>"> Download </a> 

を使用することができます設定ファイルで指定されているようにサイトのベースURLを返します。さらに、引数は、指定した文字列とそのURLを連結します。それがあなたのファイルの完全なURLになります。
