I need both session flash as well as download the csv file.

I have sample code 

In controller
function downloadErrorCSV()
    {$data=$this->tankmodel->downloadcsv();    $this->session->set_flashdata('successAddBulkTank','success');
    redirect('mypage');}
In model i have 
{some code of model} and $data='sucess'{code of download csv} and then return $data;
Now if i place exit after csv download script csv it get downloaded and if remove exit;it do not download the csv I need both download csv and show success message as well.

You have to separate your code of downloading and saving data.

I believe you don't have to save error file at server. and use javascript code to download that file.

don't download file immediately using this code $data=$this->tankmodel->downloadcsv();. save it first at server then download it later after showing message.

Saving Excel File at server: Here

Downloading of this file you can use two ways:

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

Hope this will help.

  • "thanks" but if i do so it takes too much time to execute i have 1000s of data to be uploaded.to uploading the same data twice is not better idea. – Deepak May 21 '14 at 07:02
  • @DeepakSharma i think you don't understand what i said i am not asking it two time one time is enough to save Failed data and you can download it whenever you want. – Manwal May 21 '14 at 07:19
