强制下载CSV文件

Question

我正在尝试创建一个强制CSV文件下载的按钮但由于某种原因我无法使其正常工作.这是我的代码:

public function export_to_csv($result) {

$shtml="";

for ($i=0; $i<count($result); $i++){

$shtml = $shtml.$result[$i]["order_number"]. "," .$result[$i]["first_name"]. "," .$result[$i]["middle_name"]. "," .$result[$i]["last_name"]. "," .$result[$i]["email"]. "," .$result[$i]["shipment_name"]. "," .$result[$i]["payment_name"]. "," .$result[$i]["created_on"]. "," .$result[$i]["modified_on"]. "," .$result[$i]["order_status"]. "," .$result[$i]["order_total"]. "," .$result[$i]["virtuemart_order_id"]. "\n";

}

Header('Content-Description: File Transfer');
Header('Content-Type: application/force-download');
Header('Content-Disposition: attachment; filename=pedidos.csv');

}

$ result变量来自这里:

public function get_orders_k() {

$db=JFactory::getDBO();

    $query = " select o.order_number, o.virtuemart_order_id, o.order_total, o.order_status, o.created_on, o.modified_on, u.first_name,u.middle_name,u.last_name "
    .',u.email, pm.payment_name, vsxlang.shipment_name ' .
    $from = $this->getOrdersListQuery();

$db->setQuery($query);

$result=$db->loadAssocList();

    if ( $result > 0 )
    {
        $datos = VirtueMartModelKiala::export_to_csv($result);

    }else return 0;
}

我不确定哪里开始寻找.我已经通过各种方式查看了互联网,并尝试了所有这些方法,仍然无法让它工作.请帮帮我!

-谢谢

Answer 1

将此代码放在循环下面.

header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="pedidos.csv"');

echo $shtml;

你是如何找到内容类型应用程序/强制下载的？我从来没听说过.CSV的正确MIME类型是text/csv

你可以在php手册中找到更多关于如何使用头文件功能的例子

您还需要显示$shtml您没有在代码中执行此操作.

好。您可以尝试一下，如果结果不为空，它将起作用

public function export_to_csv($result)
{
    if(!$result) return false;
    ob_end_clean();
    header( 'Content-Type: text/csv' );
    header( 'Content-Disposition: attachment;filename=pedidos.csv');
    $fp = fopen('php://output', 'w');
    $headrow = $result[0];
    fputcsv($fp, array_keys($headrow));
    foreach ($result as $data) {
        fputcsv($fp, $data);
    }
    fclose($fp);
    $contLength = ob_get_length();
    header( 'Content-Length: '.$contLength);
}
