我有以下代码，我添加了调试，这是我能够从数据库中检索的数据。我希望在视图页面中显示['User']['firstName']和['Passion']['passion_tag']，我该怎么做？我面临的错误如：
注意（8）：未定义索引：passion_tag [APP \ views \ searching \ simple_search.ctp，第127行]

答案 0 :(得分：1)
Passion没有passion_tag密钥，passion_tag位于PassionsUser。
如果$data是存储所有数据的地方，
echo $data['User']['Passion'][0]['PassionsUser']['passion_tag'];//echo first result
如果要列出所有内容，则必须遍历PassionUser数组。

看起来这是使用$this->Model->find( 'all' )检索的更大结果集的一部分，因此我假设您要显示这些结果中的所有名称。您必须遍历所有结果才能获得个人名称。此外，每个用户都有几个激情，所以如果你想要全部显示它们，你必须再次遍历它们。
echo 'Our users and their passions are: <ul>';
foreach( $this->data as $user ) {
echo '<li>';
echo $user[ 'User' ][ 'firstName' ];
echo ' who is passionate about: ';
foreach( $user[ 'Passion' ] as $passion ) {
echo $passion[ 'PassionsUser' ][ 'passion_tag' ];
echo ' ';
}
echo '</li>';
}
echo '</ul>';
