WP not sending correct headers to download a file - php

I have a WP plugin that sends a link to an email to download a file in hidden location. User selects a file, then a token containing the file ID etc. is written to a database, and a link is sent. Upon clicking the link (ex. mysite.com/thank-you/?id=asd687asd68as7d6a8sdd7sd768as7d6, the "thank you" page makes a request to a php function to donload the file.
There's also a dummy "download engine" page with a shortcode [download_page] that initiates the download.
Weird thing is that while this setup works just fine at test environment, and has worked for over a year at production site, it suddenly stopped working:
call for DownloadFile() returns 0KB and correct headers at test site, and initiates the download, but
returns full HTML file and, of course, no download.
I cannot spot any changes in configuration (both sites run WP 4.2.7). Only difference seems to be the WooCommerce plugin, and Google Analytics snippet included in production site.And that test site runs PHP 5.3 while productiopn site runs 5.6.
I'd be very grateful if somebody had an insight of what's happening.. Why are headers ignored? (There's no "Headers already sent" error.) Why is full HTML of the dummy "download engine" page displayed?
BTW it's an out-of-the-box theme, but I cannot spot no faults in it. But still, maybe.. Where I'm to look for a culprit lines? What could force a page to show full HTML instead of headers sent by php?
Relevant code is such:

Secure Direct File Downloader PHP Needs Fixes

Unfortunately, This code isn't working because i wanna download files through php and need to hide the direct path of files uploaded in my server.
If i define complete path in variable.. example.com/files/filedownload.iso then it's working but it's pointless, because i wanna hide a path while downloading.
<form target="_blank" id="download_file" action="download.php" method="post">
<input name="ip" type="hidden" value="192.123.23.1">
<input name="filename" type="hidden" value="filedownload.iso"'; ?>
<div align="center">
<input alt="Submit" src="download.gif" type="image" />
</div>
</form>
The above code is POST method..
<?php
if(isset($_POST['ip']) && $_POST['ip']!="" && isset($_POST['filename']) && $_POST['filename']!=""){
$filename = $_POST['filename'];
}
$domain="http://example.com/".$filename;
//$redirect_url="http://example.com".$filename;
$redirect_url=$path;
$redirect_url= encrypt_download_link($domain,$path);
?>
<script type="text/javascript">
var max_time= 5; //Seconds
function Redirect()
{
window.location="<?php echo $redirect_url; ?>";
}
function refresh_remaining_time()
{
max_time = max_time-1;
if (max_time>=0) {
document.getElementById("waiting_time_span").innerHTML = max_time+" Seconds";
}
}
window.onload = function() {
setInterval(function () {
if (max_time>=0) {
refresh_remaining_time();
}
}, 1000); // Execute somethingElse() every 2 seconds.
setTimeout(function () {
Redirect();
}, 5000);
};
</script>
<?php
}
function encrypt_download_link($domain,$path){
$secret = '4rTyHHgtopSUm';
$expire = strtotime("+7 days");
$md5 = base64_encode(md5($secret.$path.$expire,true));
$md5 = strtr($md5, '+/', '-_');
$md5 = str_replace('=', '', $md5);
$url = $domain.$path."?st=".$md5."&e=".$expire;
return $url;
}
?>
I'm not sure if this would work for you, and it won't work for large files, but if you redirect users to a page with this code it will stream the file in binary down to their system. Don't be a hater if your files are larger and this won't work :)
P.S. I'd love to take credit for this, and I searched for the source (couldn't find it), but this hit my library at someone else's suggestion a few years back.
$nameFile = 'insert just name of file here'
$pathFile = 'insert file and path here';
$sizeFile = filesize($pathFile);
$pointerFile = fopen($pathFile, "rb"); // Open file for reading in binary mode
$contentFile = fread($pointerFile, $sizeFile);
fclose($pointerFile);
header("Content-length: ".$sizeFile);
header("Content-type: application/octet-stream");
header("Content-disposition: attachment; filename=".$nameFile.";" );
echo $contentFile;

How to use the content-disposition header to set a downloaded UTF-8 filename?

I am storing my files on Amazon Cloud Drive. And there are option for setting response-content-disposition to direct links from Amazon.
From the API:
response-content-disposition: (Optional) If specified, the content-disposition of the response will be set to this value
I need to set it download mp3 files. I don't need to play it on browser.
And I want to set downloaded file name: Эльбрус Джанмирзоев - Кавказская любовь.mp3
I tried many ways... Urlencode... Urlencode + http build query etc...
But now the result is: Эльбрус+Джанмирзоев+-+Кавказская+любовь.mp3 when downloading files.
And here is my php code:
<?php
function file_generate_download_link($filename = false, $force = true)
{
$json['tempLink'] = 'https://content-na.drive.amazonaws.com/cdproxy/templink/iTwUqoQ3cJXOpj6T8SCDmKwtF37TAENiSLQzy7pTSbkFfJttb';
$url = $json['tempLink'];
if($force)
{
$data['download'] = 'true';
}
if($filename)
{
$data['response-content-disposition'] = ' attachment; filename*=UTF-8\'\''.urlencode($filename).'';
}
if(isset($data)) {
$data = http_build_query($data);
$url .= '?' . $data;
}
return $url;
}
echo file_generate_download_link($filename = 'Эльбрус Джанмирзоев - Кавказская любовь.mp3');
?>
This code returns me this link:
https://content-na.drive.amazonaws.com/cdproxy/templink/iTwUqoQ3cJXOpj6T8SCDmKwtF37TAENiSLQzy7pTSbkFfJttb?download=true&response-content-disposition=+attachment%3B+filename%2A%3DUTF-8%27%27%25D0%25AD%25D0%25BB%25D1%258C%25D0%25B1%25D1%2580%25D1%2583%25D1%2581%2B%25D0%2594%25D0%25B6%25D0%25B0%25D0%25BD%25D0%25BC%25D0%25B8%25D1%2580%25D0%25B7%25D0%25BE%25D0%25B5%25D0%25B2%2B-%2B%25D0%259A%25D0%25B0%25D0%25B2%25D0%25BA%25D0%25B0%25D0%25B7%25D1%2581%25D0%25BA%25D0%25B0%25D1%258F%2B%25D0%25BB%25D1%258E%25D0%25B1%25D0%25BE%25D0%25B2%25D1%258C.mp3
If I enter this link Chrome saves this file with this name:
Эльбрус+Джанмирзоев+-+Кавказская+любовь.mp3
But I need excatly save file with this name:
Эльбрус Джанмирзоев - Кавказская любовь.mp3
Where is my mistake?
Gotcha! I need to use rawurlencode function!
So the right code is:
<?php
function file_generate_download_link($filename = false, $force = true)
{
$json['tempLink'] = 'https://content-na.drive.amazonaws.com/cdproxy/templink/iTwUqoQ3cJXOpj6T8SCDmKwtF37TAENiSLQzy7pTSbkFfJttb';
$url = $json['tempLink'];
if($force)
{
$data['download'] = 'true';
}
if($filename)
{
$data['response-content-disposition'] = ' attachment; filename*=UTF-8\'\''.rawurlencode($filename).'';
}
if(isset($data)) {
$data = http_build_query($data);
$url .= '?' . $data;
}
return $url;
}
echo file_generate_download_link($filename = 'Эльбрус Джанмирзоев - Кавказская любовь.mp3');
?>

$_FILES empty at checkout

I have added a bunch of new fields to my checkout form in woocommerce. it reads in the finished php file as such;
<form name="checkout" method="post" class="checkout woocommerce-checkout processing" action="http://localhost:100/wordpress/checkout/" enctype="multipart/form-data" style="position: relative; zoom: 1;">
<div id="pagePreview">
<input type="file" name="CheckoutImageUpload">
<div class="BBtextInputFrontend">
<input class="BBTextBoxFront" placeholder="placeholder">
<input class="BBInitialValue BBData" type="text" name="BBInitialValue[]">
</div>
<div class="BBtextInputFrontend">
<input class="BBTextBoxFront" placeholder="placeholder">
<input class="BBInitialValue BBData" type="text" name="BBInitialValue[]">
</div>
</div>
<!-- the rest is the default woocommerce billing inputs -->
<div class="col2-set" id="customer_details">
<div class="col-1">
<div class="woocommerce-billing-fields">
<h3>Billing Details</h3>
the problem is that the input
<input type="file" name="CheckoutImageUpload">
never returns a value in the $_FILES array. in fact, the $_FILES array always returns an empty array. I can get the other values through $_POST with no issue. but not files. putting the plugin on a fresh install on another separate computer yields the exact same results.
I'm currently using this code to find the values:
function add_image($order_id) {
//if they DID upload a file...
if ($_FILES['CheckoutImageUpload']['name']) {
?>Y<?php
die();
}
else {
?>N<?php
die();
}
}
add_action( 'woocommerce_checkout_update_order_meta', 'add_image', 100, 1);
can anyone help? I feel like I'm losing my mind

Your file's name attribute is name="checkoutupload" but you're using $_FILES['CheckoutImageUpload'] throughout your code.
So, to keep you from changing all of the $_FILES['CheckoutImageUpload'] to the named attribute, simply change the file name attribute to name="CheckoutImageUpload".
Also make sure that the folder you are uploading to has the correct path and that it has the proper permissions to write to it.
do check var_dump($_FILES); for debugging
check $_FILES['yourFieldName']['error'] for file upload errors. php stores any errors encountered during upload, allocation, etc in ['errors']
$_FILES is an array so fwrite ($testLog , "added files: " . $_FILES); wont work var_dump should work best most of the time. (for silent debugging use a recursive foreach loop)
should you encounter errors in $_FILES['yourFieldName']['error'], most of the time the filesize is to big (php.ini) or the folder is not writeable
try the following:
function add_image($order_id) {
//var_dump($_FILES);
$errors = array();
if (
!isset($_FILES['CheckoutImageUpload']['error']) ||
is_array($_FILES['CheckoutImageUpload']['error'])
) {
$errors[] = 'Invalid file.';
}
switch ($_FILES['CheckoutImageUpload']['error']) {
case UPLOAD_ERR_OK:
break;
case UPLOAD_ERR_NO_FILE:
$errors[] = 'you sent no file';
case UPLOAD_ERR_INI_SIZE:
case UPLOAD_ERR_FORM_SIZE:
$errors[] = 'file too big'
default:
$errors[] = 'unknown error';
}
// check filesize manually
if ($_FILES['CheckoutImageUpload']['size'] > 50000) { // whatever your php.ini says
$errors[] = 'file too big';
}
return json_encode($errors);
}
Also try small text files for dev purposes. If big files fail increase these php.ini values:
max_input_time
max_execution_time
upload_max_filesize
post_max_size
session.gc_maxlifetime
I'd simplify and just test a simple file upload first
Here is a sample. Save it as test_upload.php and access it directly through your web server to test file uploads.
<?php
// test_upload.php
// Tests php file upload capabilities
if($_SERVER['REQUEST_METHOD'] == 'POST') {
echo "<pre>";
print_r($_FILES);
exit();
}
?>
<form enctype="multipart/form-data" method='post' action=''>
<input type='file' name='file' />
<input type='submit' value='submit form' />
</form>
If this doesn't work, you need to check your php.ini and also make sure that the configured temporary directory is writable by the web server.
You can find your system's temporary directory by running the following:
php -B 'echo sys_get_temp_dir(); echo "\n"; exit();'
As this is a ajax method, you need to add a ajax method to upload the files as the settings are slightly different. I think the performance of this will be poor but see what you think!
You need to check a few things in the script
1. I think i have used the correct identifer for the form (classname="checkout") examine your outputted html to ensure this is correct
2. This will only work with 1 file upload on the page, modify jQuery(document) if you need to narrow this down
3. Ajaxurl -- read the notes in the code, i'd recommend you check this first before trying the script
jQuery(form.checkout).on('submit', function(){
var fd = new FormData();
//searches the whole document, i am assuming you only need 1 file uploaded
var file = jQuery(document).find('input[type="file"]');
var individual_file = file[0].files[0];
fd.append("imagefile", individual_file);
fd.append('action', 'upload_image');
jQuery.ajax({
type: 'POST',
url: ajaxurl, // nb-----------------have you got a variable for ajaxurl? if not insert var ajaxurl = '<?php echo admin_url('admin-ajax.php'); ?>'; somewhere in your template...or google the wp way!
data: fd,
contentType: false,
processData: false,
success: function(response){
//just spit out the response to the console to catch php errors etc..
console.log(response);
}
});
});
In your functions.php...
function upload_image(){
echo 'action had been called';
var_dump($_FILES);
// work with files!
}
add_action('wp_ajax_upload_image', 'upload_image');
add_action('wp_ajax_nopriv_upload_image', 'upload_image');
Did you dump the $_FILES completly?
Maybe you have an other field with the same form name.
If you would have posted the complet form it would be easier (as already mentioned).
Another reason might be, that your php stack doesn't have write permission to the upload folder and then returns nothing.
Check your server logs.
It might tell you what happened.
Something else I just thought off.
Use Crome and check what requests have been fired.
But make shure that you hightlited the checkbox in the network section to persist the session.
Your Browser might reload the page without you recognizing it.

Export CSV File in Wordpress

there is a button on my settings that once clicked it will prompt to download a csv file. Here is the code.
<?php
/** Step 2 (from text above). */
add_action( 'admin_menu', 'my_plugin_menu' );
/** Step 1. */
function my_plugin_menu() {
add_options_page( 'Members Log Data',
'Members Log',
'manage_options',
'sj-member-option',
'members_option' );
}
/** Step 3. */
function members_option() {
if ( !current_user_can( 'manage_options' ) )
{
wp_die( __( 'You do not have sufficient permissions to access this page.' ) );
}
$name = "member-log-".date('Y-m-d');
$list[] = array('username','no of favorites');
header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=' . $name);
$op = fopen('php://output','w');
foreach($list as $row)
{
fputcsv($op,$row);
}
fclose($op);
/*
echo '<div class="wrap">';
echo '<p>Here is where the form would go if I actually had options.</p>';
echo '</div>';
*/
}
I am getting can not modify session header.
I would like to ask how to do this in WP as I am familiar outside of it.
You're trying to send a header command too late, hence the error. Use the hook load-(your_page) for this kind of output.
function my_plugin_menu() {
$page = add_options_page( 'Members Log Data',
'Members Log',
'manage_options',
'sj-member-option',
'members_option' );
add_action( "load-$page", 'do_export' );
}
In the members_option function callback add a <form> with a submit button and in the new do_export function you'll put the export actions. Something like bellow, note that I'm not checking for the nonce, but for security best practices you should do it instead of checking for $_POST['submit'].
function members_option() {
if ( !current_user_can( 'manage_options' ) )
{
wp_die( __( 'You do not have sufficient permissions to access this page.' ) );
}
?>
<form method='post' >
<p class="submit">
<?php wp_nonce_field('my-import'); ?>
<input type='submit' name='submit' value='Restore'/>
</p>
</form>
<?php
}
function do_export() {
if( isset( $_POST['submit'] ) && 'Restore' == $_POST['submit'] )
{
$name = "member-log-".date('Y-m-d');
$list[] = array('username','no of favorites');
header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=' . $name);
$op = fopen('php://output','w');
foreach($list as $row)
{
fputcsv($op,$row);
}
fclose($op);
}
}
In my tests, the export result was an HTML file with the full contents of the page plus the 'username','no of favorites' that you defined, but this is a matter for another question/research.

Mediawiki Extension add Javascript in Header

Hi my problem is that i cant load some javascript file # my special page extension.
I tried it with addscript and some other methods but the only thing what happened was that the javascript was canceled cause no-js of the mediawiki software.
In the folder of my extension is a new.js file which i want to have access only on my special page.
Here is some code (most of it of the example of the special pages).
MyExentions.php
<?php
if (!defined('MEDIAWIKI')) {
echo <<<EOT
To install my extension, put the following line in LocalSettings.php:
require_once( "$IP/extensions/MyExtension/MyExtension.php" );
EOT;
exit( 1 );
}
$wgExtensionCredits['specialpage'][] = array(
'path' => __FILE__,
'name' => '-',
'author' => 'Thomas Döring',
'descriptionmsg' => '-',
'version' => '0.0.1',
);
$dir = dirname(__FILE__) . '/';
$wgAutoloadClasses['SpecialMyExtension'] = $dir . 'SpecialMyExtension.php';
$wgExtensionMessagesFiles['MyExtension'] = $dir . 'MyExtension.i18n.php';
$wgExtensionMessagesFiles['MyExtensionAlias'] = $dir . 'MyExtension.alias.php';
$wgSpecialPages['MyExtension'] = 'SpecialMyExtension';
SpecialMyExtension.php
<?php
class SpecialMyExtension extends SpecialPage {
function __construct() {
parent::__construct( 'MyExtension' );
}
function execute( $par ) {
$request = $this->getRequest();
$output = $this->getOutput();
$this->setHeaders();
# Get request data from, e.g.
$param = $request->getText('param');
# Do stuff
# ...
if(file_exists("extensions/TimeLine/TimeLine/data.xml"))
{
$data = simplexml_load_file("extensions/TimeLine/TimeLine/data.xml");
foreach($data->event as $event)
{
$html.="<tr><td>".$event['title']."</td><td>".$event['start']."</td></tr>";
}
$html.="</table>";
$html.="klick";
$output->addHTML($html);
}
else
{
$wikitext = 'Datei nicht gefunden!';
$output->addWikiText( $wikitext );
}
}
}
?>
I hope you can help me.
addScript works in version 1.16 and before. In 1.17 and later you should use addHeadItem:
$wgHooks['ParserBeforeTidy'][] = 'wgAddJquery';
function wgAddJquery(&$parser, &$text) {
global $addJqueryScripts;
if ($addJqueryScripts === true) return true;
$parser->mOutput->addHeadItem(
'<script language="JavaScript" src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js" type="text/javascript"></script>'
);
$addJqueryScripts = true;
return true;
}
I added it in the skin file, in the function function setupSkinUserCss
$out->addHeadItem('maketree.js',"
<script type='text/javascript' src='/js/mktree.js'></script>");
