Question

我正在尝试导出到CakePHP中的CSV，因为我是Cake的新手，请与我一起出去，并且被要求在短时间内执行此操作。

基本上我遇到的问题是，数据库被拆分为多个表。一个用于产品，一个用于艺术家，一个用于用户。

除了艺术家的电子邮件地址存储在用户表中之外，这一切都很好，我希望这些包含在导出中。我已经尝试添加列（csv）的相应标题，然后添加 $结果[＆＃39;用户＆＃39;] [＆＃39;用户名＆＃39]，可以在下面的完整功能中看到的行，但是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);
}

Answer 1

如果您正在遵循蛋糕规定，那么它应该是

$result['User']['username'],

（型号名称必须是单数而不是复数）

在看到Scuplure模型文件后编辑：

因为User与Artist Model相关（而不是直接与Sculpture Model相关），您必须在find调用中设置'recursive'参数：

$results = $this->Sculpture->find(
    'all', 
    array(
        'conditions' => array('event_id' => $event_id), 
        'order' => 'artist_id',
        'recursive' => 2
    )
);

CSV导出包括来自其他表的行
