Question

我正在使用Yii 1框架。我尝试将表详细信息下载为.csv文件，并使用ID从表中检索数据。

单击按钮时，它将检索数据并显示在inspect元素的Network部分中。没有错误，只有问题是不下载文件。

这是控制器方法的代码。

public function actionDownload()
{


    $id = $_REQUEST['id'];


    $vote_record = Vote::model()->findByAttributes(array('id' => $id));


    $name = $vote_record['name'];

    header('Content-Description: File Transfer');
    header("Content-type: application/csv");
    header('Content-Disposition: attachment; filename="'. str_replace(" ", "_", strtolower($name)) . '_results.csv"');
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    ob_clean();
    flush();



    $titile = "Option, Vote Count\n";
    echo $titile;
    if (count($vote_record) > 0) {

        echo $vote_record['name'] . "," . $vote_record['total'] . "\n";

        echo "\n\n";
        echo $vote_record['opname1'] . "," . $vote_record['voteCount1'] . "\n";
        echo $vote_record['opname2'] . "," . $vote_record['voteCount2'] . "\n";
        echo $vote_record['opname3'] . "," . $vote_record['voteCount3'] . "\n";
        echo $vote_record['opname4'] . "," . $vote_record['voteCount4'] . "\n";

    }
}

所以请帮助解决这个问题。

Answer 1

您可以针对您的问题尝试此解决方案：

<?php 
public function actionDownload() {
    $id = $_REQUEST['id'];
    $vote_record = Vote::model()->findByAttributes(array('id' => $id));
    $name = $vote_record['name'];

    header("Content-type: application/csv");
    header('Content-Disposition: attachment; filename="'. str_replace(" ", "_", strtolower($name)) . '_results.csv"');
    header("Pragma: no-cache");
    header("Expires: 0");

    $handle = fopen('php://output', 'w');
    if (count($vote_record) > 0) {
        fputcsv($handle, array('Option', 'Vote Count'));
        fputcsv($handle, array($vote_record['name'], $vote_record['total']));
        fputcsv($handle, array($vote_record['opname1'], $vote_record['voteCount1']));
        fputcsv($handle, array($vote_record['opname2'], $vote_record['voteCount2']));
        fputcsv($handle, array($vote_record['opname3'], $vote_record['voteCount3']));
        fputcsv($handle, array($vote_record['opname4'], $vote_record['voteCount4']));
        fclose($handle);
        exit;
    }
    ob_clean();
    flush();
}
?>

我希望它会有所帮助。
