ベイク スクリプトを使用してベイクした単純な cakephp 2.x アプリがあります。2 つの主要なテーブルは状態と薬です。状態 HABTM 薬とその逆。状態インデックスの状態に属する薬を表示しようとしています。基本的にはすべての状態をリストしていますが、それらの薬のみです。別の 1.3 アプリで動作するコンマ区切りのリストにある状態に属する薬を表示するために、次のようにしてみました。
<?php
$condition_drugs = '';
foreach($condition['Drug'] as $drug):
$condition_drugs .= $drug['drug'] . ', ';
//echo $drug['generic'];
endforeach;
//echo substr($condition_drugs, 0, -2);
echo $condition_drugs;
?>
ただし、次の 2 つのエラーが発生します: Undefined index: Drug [APP/View/Conditions/index.ctp、22 行目]、および foreach() に無効な引数が提供されました [APP/View/Conditions/index.ctp、22 行目]
また、同様の方法でそれを行うことを提案した別の記事も見ました。私が持っているコードに何か問題がありますか? ID に基づいてモデルを検索する必要がありますか? インデックス ビューの完全なコードとコントローラーは次のとおりです。
