Question

我有一个像这样的数组

$csvDownload=Array
    (
        [0] => Array
            (
                [serial] => Serial
                [volume] => Tanksize
                [manufacturer] => Manufacturer
                [manufacturerDate] => manufacturerDate
                [warehouse] => Warehousename
                [pickLocation] => PickupLocation
                [pickDate] => pickDate
                [CompanyName] => Company
                [nationalBoard] => nationalBoard
            )
        [1] => Array
            (
                [serial] => 20001
                [volume] => 120H
                [manufacturer] => Atlas
                [manufacturerDate] => 2013
                [warehouse] => WAREHOUSE1
                [pickLocation] => kanpur
                [pickDate] => 2/25/2014
                [CompanyName] => WIM
                [nationalBoard] => he
            )
        );

我需要做的是

1）下载csv

2）之后将$ data返回给控制器如果我在返回代码之后使用退出，则下载csv文件但会话不会打印。如果我从代码会话消息打印中删除退出，但csv不下载

Please help what i am doing wrong or any way to solve this..!
I need both session flash as well as download the csv file.

我有示例代码

In controller

function downloadErrorCSV()
    {$data=$this->tankmodel->downloadcsv();    $this->session->set_flashdata('successAddBulkTank','success');
    redirect('mypage');}

在模型中我有

{some code of model} and $data='sucess'{code of download csv} and then return $data;

现在如果我在csv下载脚本csv之后放置它会被下载并且如果删除退出;它不下载csv我需要两者下载 csv和显示成功消息。

您必须将下载和保存数据的代码分开。

我相信您不必在服务器上保存错误文件。并使用javascript代码下载该文件。

请勿使用以下代码立即下载文件 ~~$ data = $ this-＆gt; tankmodel-＆gt; downloadcsv（）;~~ 。首先将其保存在服务器上，然后在显示消息后再下载。

在服务器上保存Excel文件：Here

下载此文件可以使用两种方式：

Javasctipt location.href = 'http://sitefullpath/yourfilename';
iframe：[iframe src="yourfilename"][/iframe]

希望这会有所帮助。

CSV文件不下载codeigniter
