Using fputcsv function to output data - php

I'm using http headers declaring that content, then I am using the PHP function fputcsv to output data:
header("Content-type: application/vnd.ms-excel");
header("Content-disposition: attachment; filename=organisation.csv");
header("Cache-Control: must-revalidate");
header("Pragma: must-revalidate");
header('Expires: 0');
header('X-Content-Type-Options: nosniff');
$file = fopen('php://output', 'w');
fputcsv($file, array('Post ID', 'Post title', 'URL'));
When I run this is exporting data correctly. However I would like to split the data into different sheets/tabs within the csv.
Is this at all possible?

Wordpress converting array to csv for download

I have the following function that takes an array of results from a database query. I populate the array as I loop through the query results. At the same time I create an html table. After outputting the html table I call the function download_csv($csvArray) but no downloading of the CSV happens, It just displays the contents of the the array as if I did a var_dump on the array. I can confirm that the contents of the array are correct.
Note: this is being done on an external web page not from the admin area.
Is there some wordpress function that needs to be called to allow the download or am I missing something?
function download_csv($csvArray) {
$file_name = 'report.csv';
//output headers so that the file is downloaded rather than displayed
header("Content-Type: text/csv");
header("Content-Disposition: attachment; filename=$file_name");
//Disable caching - HTTP 1.1
header("Cache-Control: no-cache, no-store, must-revalidate");
//Disable caching - HTTP 1.0
header("Pragma: no-cache");
//Disable caching - Proxies
header("Expires: 0");
//Start the ouput
$output = fopen("php://output", "w");
//Then loop through the rows
foreach ($csvArray as $fields) {
fputcsv($output, $fields);
}
//Close the stream off
fclose($output);
die();
}
Following Code will help you to convert Array to CSV and Make it to automatically download Change the die(); function to exit(); And Use Implode function. It will work.
header('Content-Type: text/csv; charset=UTF-8');
header('Content-Disposition: attachment; filename=sample.csv');
header('Pragma: no-cache');
header('Expires: 0');
$fp = fopen('php://output', 'w');
//ex: $list={...};
foreach ($list as $fields)
{
fputcsv($fp,implode($fields, ','));
}
fclose($fp);
exit();

Php / Codeigniter File Download

I'm trying to download file in php. I used both codeigniter download helper and pure php code readfile. I can get the contents of file in browser's Network but I can not download it.
When I tried the readfile function in an independent php file it worked.
Here is my code block for dowload file.
// codeigniter
$this->load->helper('download');
$data = file_get_contents(base_url("/images/logo.png"));
force_download($decodedFileInfo->fileName, $data);
// php readfile
$file = "./images/logo.png"; //. $decodedFileInfo->fileName;
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}else{
var_dump("hst");die;
}
Thank you..
Try Saving the file name and image name in variables and echo them on the screen.
I tested this functions works perfectly:
$this->load->dbutil();
//Calling a store procedure
$sp ="exec secondProc '5 Aug 2013'";
$query = $sqlsrvr->query($sp);//->result();
$jawad = $query->result_array();
//pass it to db utility function
$new_report = $this->dbutil->csv_from_result($query);
//Downloading the file
$this->load->helper('download');
force_download('csv_file.csv', $new_report);
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header('Content-Description: File Transfer');
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename={$name}");
header("Expires: 0");
header("Pragma: public");

Using CodeIgniter to download CSV of results

We run queries using CodeIgniter against our MySQL database, and display those results on the page. Sometimes, we want to download those as a CSV. The guy before me set up this download button, but it does not function at all. Never has.
This is the existing code for the download:
public function download_csv_search(){
$dbresults = $this->do_search();
$results = $dbresults['results'];
$csv = "First Name, Last Name, MI, Age, Details(RA), Status, Home Phone, Gender, Notes\n";
$filename = "data_export";
//header('Content-Type: text/csv; charset=utf-8');
//header('Content-Disposition: attachment; filename=data.csv');
//$output = fopen('php://output', 'w');
//fputcsv($output, array('First Name', 'Last Name', 'Middle Name', 'DOB', 'Details(RA)', 'Status', 'Home Phone', 'Gender', 'Notes'));
foreach($results as $result) {
$birthday_timestamp = strtotime($result->VoterDOB);
$age = date('md', $birthday_timestamp) > date('md') ? date('Y') - date('Y', $birthday_timestamp) - 1 : date('Y') - date('Y', $birthday_timestamp);
$csv .= $result->VoterFN.",".$result->VoterLN.",".$result->VoterMN.",".$dob.",".$result->Street.",".$result->VoterStatusID.",".$result->phone.",N/A,\n";
// $dataArray = array('VoterFN'=>$result->VoterFN, 'VoterLN'=>$result->$VoterLN, 'VoterMN'=>$result->VoterMN,'VoterDOB'=>$result->date('m/d/Y', strtotime($result->VoterDOB)), 'Street'=>$result->Street, "VoterStatusID"=>$result->VoterStatusID,'phone'=>$result->phone);
//fputcsv($output, $dataArray);
}
//OUPUT HEADERS
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$filename.csv\";" );
header("Content-Transfer-Encoding: binary");
//OUTPUT CSV CONTENT
echo($csv);
exit();
}
I'm guessing I need to use the download helper + the force_download function, but I can't seem to get it. Any ideas?
I think you have so many headers, but more important, if the file is a CSV, why sending it as a binary file? Why aren't you using text/csv? I only use the following code, I suppose that Cache-Control is to avoid downloading the same file without hit the server. Anyway, only with:
header('Content-type: text/csv');
header("Content-Disposition: attachment; filename=\"$filename.csv\";" );
should work. After a bit of research in SO, depending on what browser you use you may have problems with your Cache headers:
Creating and downloading CSV with PHP, so research a bit that in order to avoid future issues.

In php Instead of downloading csv file it gets open in the browser

I'm trying to download a CSV file through the browser. The script is partially working, because so far I managed to display the CSV on screen, but the download is not starting.
Here is what i tried so far:
if(isset($currency)) {
header("Content-Type: application/csv");
header("Content-Disposition: attachment;Filename=Pricelogs.csv");
ob_clean();
$filename = "/tmp/".uniqid().".csv";
exportCSVFile($filename, $currency, $country, $provider);
readfile($filename);
//unlink("'".$filename."'");
} else {
echo "ERR_USERNAME_PASSWORD";
exit();
}
I had already read all questions of this type from FAQ & also tried but it gets open on browser only,instead of downloading.
I had also used header with single quotes.
I also tried header("Content-Type: text/csv");
Also:
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers
header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=\"".$filename."\";" );
header("Content-Transfer-Encoding: binary");
PUT your CSV file URL, it will display in browser in place of force browser to download. You can open it in iframe in your site.
http://docs.google.com/viewer?embedded=true&url=www.yoursite.com/filename.csv
I usually just do:
header('Content-type: text/csv');
header("Content-Disposition: attachment; filename=my_csv_filename.csv");
// print CSV lines here
exit();
I can tell you this combination is working for me:
$bom = chr(0xEF) . chr(0xBB) . chr(0xBF);
header("Content-type: application/csv; charset=UTF-8");
header("Content-Disposition: attachment; filename=$filename.csv");
header("Pragma: no-cache");
header("Expires: 0");
print $bom . $data;
exit;
If I were you, I would first test this plainly (outside of all your buffering), first see that you manage to make this work, and only then test it in your specific set up.
You might try this.
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$filename.csv\";" );
print $content;
For large files you need to get your output buffer started
add : ob_start(); at the start
ob_clean(); at the end of you file

PHP Excel Output for IE gives empty file

I am trying to generate an excel file with php. This works fine in Firefox but with IE I am only getting an empty file. This is what I am doing basically:
header('Content-type: application/ms-excel');
header('Content-Disposition: inline; attachment; filename='.$filename);
echo $data;
I have tried various header settings but no success. I have also tried to output the content as a text file, same result here. No content in IE.
Any ideas?
header("Cache-Control: no-stor,no-cache,must-revalidate");
header("Cache-Control: post-check=0,pre-check=0", false);
header("Cache-control: private");
header("Content-Type: application/octet-stream");
header('Content-Disposition: inline; attachment; filename='.$filename);
header("Content-Transfer-Encoding: binary");
header("Pragma: no-cache");
header("Expires: 0");
--
header('Pragma: public');
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
header('Last-Modified: '.gmdate('D, d M Y H:i:s') . ' GMT');
header('Cache-Control: no-store, no-cache, must-revalidate');
header('Cache-Control: pre-check=0, post-check=0, max-age=0');
header ("Pragma: no-cache");
header("Expires: 0");
header('Content-Transfer-Encoding: none');
header('Content-Type: application/vnd.ms-excel;');
header("Content-type: application/x-msexcel");
header('Content-Disposition: inline; attachment; filename='.$filename);
Just two Options, also tried some other combinations.
Thanks,
Roland
Had the same problem: IE times out after some short time if it doesn't get a response, even if the TCP connection is still open. What helped me was this: disable output buffering, send headers and flush them out. Send data when you have them. This was enough to keep the connection open.
Something like this:
// reset all output buffering
while (ob_get_level() > 0) {
ob_end_clean();
}
header('Content-type: application/ms-excel');
header('Content-Disposition: inline; attachment; filename='.$filename);
// we can't send any more headers after this
flush();
$excel = new PhpExcel();
$excel->setActiveSheetIndex(0);
$sheet = $excel->getActiveSheet();
// in this example, $data was an array in the format row => value
// data structure is not relevant to issue
foreach ($data as $key => $value) {
// add data to sheet here
$sheet->SetCellValue('A' . $key, $value);
// etc...
}
$writer = new PHPExcel_Writer($excel);
// push to browser
$writer->save('php://output');
Set your header to header("Content-Type: application/octet-stream"); to force a download.
or another version of your header is adding vnd so application/vnd.ms-excel but if you send this header then you should also send your current header along side it as some browsers vary.
