How to download a text file on link click in codeigniter - php

Question

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?

Answer 2

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"

Answer 3

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>

Answer 4

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));
}
