I am using this script to show a csv file:
if (isset($_GET['csv'])) {
header('Content-Type: text/csv; charset=utf-8');
$out = fopen('php://output', 'w');
foreach ($dataArray as $k => $v) {
fputcsv($out, $v);
}
fclose($out);
exit();
}
And this Javascript to open the csv for a direct download:
<a href="#" class="export" onclick="window.open(window.location.pathname + window.location.search + \'&csv=1\');">
Now I want to change the filename to something like:
subscriptions_2014_10_23.csv
Someone knows how to do so?
You need to add another header specifying the file name. Then throw in some date function to add into that:
$filename = 'subscriptions_' . date('Y_m_d') . '.csv';
header('Content-Disposition: attachment; filename="' . $filename . '"');
Just add one more header
header('Content-Disposition: attachment; filename=subscriptions_2014_10_23.csv');
maybe you should use header for file name :
header('Content-Disposition: attachment; subscriptions_2014_10_23.csv"');

I'm currently trying to make a file download in the user's browser but have so far been unable to make it happen.
I've looked at other answers on stackoverflow.com and so far haven't found anything that has solved my problem.
My process is as follows:
I create the filename and filepath, then set headers:
$date = new DateTime();
$currentDateTime = $date->format("Y-m-d H:i:s");
$filename = "{$name}_{$currentDateTime}.csv";
$filepath = $rootfull . "/{$filename}";
// Set headers
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename="' . $filepath . '"');
header('Content-Length: ' . filesize($filepath));
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header("Content-Transfer-Encoding: binary");
header('Pragma: no-cache');
I then create the file and start writing to it:
// Write header
fputcsv($output, $header);
fputcsv($output, array()); // Empty line
// Write column names
$column_headers = array_keys(array_flip($columns));
foreach ($data as $row)
{
fputcsv($output, $row);
}
echo readfile($filepath);
die();
The file gets generated and written to the specified location (in this case /var/www/<project>/<filename>.csv without any indication to the user that anything has happened. No download dialog, nothing.
If anyone can spot a problem with my code or my process, please point it out and preferably suggest a better/alternative way of doing it, any help at all is welcome at this point.
If no benefit (poor mans cache) to writing to disk then maybe something like this writing to buffer:
<?php
header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename="dump_' . date('Ymd') . '.csv"');
header("Pragma: no-cache");
header("Expires: 0");
$this->outputCSV($results);
exit(); //->
public function outputCSV($data, $useKeysForHeaderRow = true)
{
if ($useKeysForHeaderRow) {
array_unshift($data, array_keys(reset($data)));
}
$outputBuffer = fopen("php://output", 'w');
foreach($data as $v) {
fputcsv($outputBuffer, $v);
}
fclose($outputBuffer);
}
?>
I'm using following headers to generate excel file from database MySQL using PHP
header("Content-type: application/octet-stream");
header("Content-Type: application/vnd-ms-excel");
header("Content-disposition: attachments;filename=xxx.xls");
in localhost the output is xxx.xls which is correct file but in the server side i am getting xxx.php file (i am using a cpanel account for ftp)
guys please help me with a solution
simply use
header('Content-type: application/vnd.ms-excel');
header('Content-Disposition: attachment; filename="file.xls"');
Simply you can use the following php code.
You have to give an array with key value pair
$data = array("Name"=> "foo", "age" => 25);
$filename = "My File Name" . date('Ymd') . ".xls";
header("Content-Disposition: attachment; filename=\"$filename\"");
header("Content-Type: application/vnd.ms-excel");
$flag = false;
foreach($data as $row) {
if(!$flag) {
// display field/column names as first row
echo implode("\t", array_keys($row)) . "\n";
$flag = true;
}
foreach ($row as $value){
echo $value;
echo "\t";
}
echo "\n";
}
exit;
I have text file contains Sample of CSV file format, I want my users can download that file on a link click.
This file resides in this folder stucture:
assets->csv->Sample-CSV-Format.txt
This is the code that I have tried to far:
<?php
$file_name = "Sample-CSV-Format.txt";
// extracting the extension:
$ext = substr($file_name, strpos($file_name,'.') + 1);
header('Content-disposition: attachment; filename=' . $file_name);
if (strtolower($ext) == "txt") {
// works for txt only
header('Content-type: text/plain');
} else {
// works for all
header('Content-type: application/' . $ext);extensions except txt
}
readfile($decrypted_file_path);
?>
<p class="text-center">Download the Sample file HERE It has a sample of one entry</p>
This code is downloading the file on page load instead of link click. Also, it is downloading the whole html structure of the page I want only the text what I have written in text file.
Please guide where is the issue?
You can do this simply in by HTML5 download atrribute . Just add this line in your downloading link .
HERE
You can do it like this, it won't redirect you and also works good for larger files.
In your controller "Controller.php"
function downloadFile(){
$yourFile = "Sample-CSV-Format.txt";
$file = #fopen($yourFile, "rb");
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=TheNameYouWant.txt');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($yourFile));
while (!feof($file)) {
print(#fread($file, 1024 * 8));
ob_flush();
flush();
}
}
In your view "view.php"
Download
make it like this
someother_file.php
<?php
$file_name = "Sample-CSV-Format.txt";
// extracting the extension:
$ext = substr($file_name, strpos($file_name,'.')+1);
header('Content-disposition: attachment; filename='.$file_name);
if(strtolower($ext) == "txt")
{
header('Content-type: text/plain'); // works for txt only
}
else
{
header('Content-type: application/'.$ext); // works for all extensions except txt
}
readfile($decrypted_file_path);
?>
some_html_page.html
<p class="text-center">Download the Sample file HERE It has a sample of one entry</p>
To my view its better to have the download code to the client side, than to have a controller-method written for this.
you can use this ref
public function getTxt()
{
$this->load->helper('download');
$dataFile = "NOTE87";
$dataContent = array();
$dt = "Date :23/07/2021";
$dataContent= array(
"\n",
"\t\t\tUTI AMC Limited\n",
"\t\tDepartment of Fund Accounts\n",
"\n",
"\tReissue of Non Sale Remittance - Axis Bank Cases\n",
"\n",
"\t\t\t\tDate :".$dt."\n",
"\n",
);
force_download($dataFile,implode($dataContent));
}
I need some eduction please.
At the end of each month, I want to download some data from my webserver to my local PC.
So, I've written a little script for that, which selects the data from the DB.
Next, I want to download it.
I've tried this:
$file=$month . '.txt';
$handle=fopen($file, "w");
header("Content-Type: application/text");
header("Content-Disposition: attachment, filename=" . $month . '.txt');
while ($row=mysql_fetch_array($res))
{
$writestring = $row['data_I_want'] . "\r\n";
fwrite($handle, $writestring);
}
fclose($handle);
If I run this, then the file is created, but my file doesn't contain the data that I want. Instead I get a dump from the HTML-file in my browser..
What am I doing wrong..
Thanks,
Xpoes
Below script will help you download the file created
//Below is where you create particular month's text file
$file=$month . '.txt';
$handle=fopen($file, "w");
while ($row=mysql_fetch_array($res)){
$writestring = $row['data_I_want'] . "\r\n";
fwrite($handle, $writestring);
}
fclose($handle);
//Now the file is ready with data from database
//Add below to download the text file created
$filename = $file; //name of the file
$filepath = $file; //location of the file. I have put $file since your file is create on the same folder where this script is
header("Cache-control: private");
header("Content-type: application/force-download");
header("Content-transfer-encoding: binary\n");
header("Content-disposition: attachment; filename=\"$filename\"");
header("Content-Length: ".filesize($filepath));
readfile($filepath);
exit;
Your current code does not output a file, it just sends headers.
in order for your script to work add the following code after your fclose statement.
$data = file_get_contents($file);
echo $data;
I have to create one text file and make it downloadable without saving to my directory on button click.
Below I have mentioned code of my file that generate file.
<?php
$data = "ffff dfjdhjf jhfjhf f f hlm hoejrherueirybgb,nvbd;ihrtmrn.";
$filename = "SU_Project_Startup.txt";
$fh = fopen($filename, "w+");
fwrite($fh, $data, strlen($data));
fclose($fh);
header('Content-type: application/octet-stream');
header('Content-Disposition: attachment; filename="' . $filename . '"');
ob_end_flush();
echo $data;
exit();
?>
Can you tell me which changes still I have to do in this code?
Thanks in advance
Try this headers:
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=$file");
header("Content-Type: application/json"); // here is your type
header("Content-Transfer-Encoding: binary");
This is an example of taking pictures of the url
you can try it, or put it into function
<?php
header('Content-type: application/octet-stream');
header('Content-Disposition: attachment; filename="File-name.jpg"');
$fileurl = 'http://upload.wikimedia.org/wikipedia/commons/thumb/c/cc/Ramses_II_at_Kadesh.jpg/120px-Ramses_II_at_Kadesh.jpg';
$data = file_get_contents($fileurl);
echo $data;
?>
