我正在尝试在 CakePHP 中导出到 CSV。
基本上我遇到的问题是，数据库被分成多个表。 一种用于产品，一种用于艺术家，一种用于用户。
除了艺术家的电子邮件地址存储在用户表中之外，一切都运行良好，我希望将这些包含在导出中。我尝试为列(csv)添加适当的标题，然后添加 $结果['用户']['用户名'], 可以在下面的完整功能中看到该行，但它将电子邮件字段留空。请帮忙!
function export($event_id)
{
$this->layout = 'blank_layout';
ini_set('max_execution_time', 600); //increase max_execution_time to 10 min if data set is very large
//create a file
$filename = "export_".date("Y.m.d").".csv";
$csv_file = fopen('php://output', 'w');
header('Content-type: application/csv');
header('Content-Disposition: attachment; filename="'.$filename.'"');
$results = $this->Sculpture->find('all', array('conditions' => array('event_id' => $event_id), 'order' => 'artist_id'));
// The column headings of your .csv file
$header_row = array(
"Artist",
"Email",
"Sculpture",
"Materials",
"Description",
"Price",
"Notes"
);
fputcsv($csv_file,$header_row,',','"');
// Each iteration of this while loop will be a row in your .csv file where each field corresponds to the heading of the column
foreach($results as $result)
{
// Array indexes correspond to the field names in your db table(s)
$row = array(
$result['Artist']['name'],
$result['Users']['username'],
$result['Sculpture']['title'],
$result['Sculpture']['materials'],
$result['Sculpture']['description'],
$result['Sculpture']['price'],
$result['Sculpture']['notes'],
);
fputcsv($csv_file,$row,',','"');
}
fclose($csv_file);
}

最佳答案
如果你遵循蛋糕命名惯例，它应该是
$result['User']['username'],
(型号名称必须是单数，不能是复数)
看到Scuplure模型文件后编辑:
因为用户与艺术家模型相关(而不是直接与雕塑模型相关)，所以您必须在查找调用中设置“递归”参数:
$results = $this->Sculpture->find(
'all',
array(
'conditions' => array('event_id' => $event_id),
'order' => 'artist_id',
'recursive' => 2
)
);
