Am developing a code that creates a ZIP file out of selected files from a folder. The folder is created with sessiontime as name, but the files are not added to the ZIP file. The permissions of files are 777. The files are getting selected, indicated by the output below. I have also checked the code by replacing with line $zip->addFile($file_folder); which downloads a blank zip archive, hence there is no issue with it.
<?php
ob_start();
$error = ""; //error holder
if(isset($_POST['createpdf']))
{
$post = $_POST;
$file_folder = "test/".$_SESSION["dir_name"]."/"; // folder to load files
echo $file_folder;
if(extension_loaded('zip'))
{ // Checking ZIP extension is available
echo "checking";
if(isset($post['files']) and count($post['files']) > 0)
{ echo "/checking2";// Checking files are selected
$zip = new ZipArchive(); // Load zip library
$zip_name = time().".zip"; // Zip name
if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE)
{
// Opening zip file to load files
echo "* Sorry ZIP creation failed at this time<br/>";
}
foreach($post['files'] as $file)
{ echo "added";
$zip->addFile($file_folder.$file); // Adding files
into zip
}
$zip->close();
if(file_exists($zip_name))
{
// push to download the zip
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$zip_name.'"');
readfile($zip_name);
// remove zip file is exists in temp path
unlink($zip_name);
The output I get is the line : test//checking/checking2addedaddedadded
You forgot session_start() after opening the <?php tag, so your $_SESSION['dir_name'] variable is empty

I have a web service that is requesting for data. The data received is being stored in the variable $response.
After that, i am creating files to store the data.
Then i am trying to add these files to a zip and afterwards download that zip. I have consulted various questions and answers similar to mine but i still cannot solve my problem. Note that i have the zip library installed.
Below is my php script:
// Load zip library
$zip = new ZipArchive();
//Zip name
$zip_name = "data.zip";
if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE){
// Opening zip file to load files
$error = "ZIP creation failed at this time";
}
else{
echo "zip creation successful";
}
function myFunc(){
//Some codes
global $zip;
$myfile = fopen($filepath, "w");
fwrite($myfile, $response);
fclose($myfile);
echo "test1";
try {
//add file to zip
$zip->addFile($myfile);
}
catch (Exception $e) {
echo $e->getMessage();
}
echo "test2";
}
$zip->close();
//Some codes
if(file_exists($zip_name)){
// push to download the zip
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$zip_name.'"');
readfile($zip_name);
// remove zip file is exists in temp path
unlink($zip_name);
}
After running the above script, test1 is being displayed and not test2. I think that the problem lies in this line $zip->addFile($myfile);.
From previous posts, i could notice that the function addFile takes 2 parameters. How can i edit my code for this?
Thanks for your help.
I'm creating a zip with php with big files like videos. The ZIP should be around 500mb and the php crash with 504 Gateway TimeOut when i try to makeit. I want to add a progress bar or something to avoid the server saturation, i think the key is in the foreach when add files.
foreach($post['files'] as $file) {
$zip->addFile($file,basename($file));
}
i already setup max_execution_time
ini_set('max_execution_time', 0);
Any idea how is the best way?
Complete code:
<?php
set_time_limit(0);
ini_set('max_execution_time', 0);
if(isset($_POST['files']))
{ $error = ""; //error holder
{
$post = $_POST;
$file_folder = "files/"; // folder to load files
if(extension_loaded('zip'))
{
// Checking ZIP extension is available
if(isset($post['files']) and count($post['files']) > 0)
{
// Checking files are selected
$casting_titulo = $post['casting_titulo'];
$zip = new ZipArchive(); // Load zip library
$zip_name = $titulo."cast.zip"; // Zip name
if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE)
{
// Opening zip file to load files
$error .= "* Sorry ZIP creation failed at this time";
}
foreach($post['files'] as $file) {
$zip->addFile($file,basename($file));
}
$zip->close();
if(file_exists($zip_name))
{
// push to download the zip
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$zip_name.'"');
readfile($zip_name);
// remove zip file is exists in temp path
unlink($zip_name);
}}
else $error .= "* Please select file to zip "; }
else $error .= "* You dont have ZIP extension"; }
}
?>
So I am doing a localhost website for fonts, and I managed to let the user select multiple files into a cart, it can be download if they are from the same folder for example either C:/fonts/a or C:/fonts/b but if there are files from both a and b, it can't be downloaded
So is it possible to do that? like download selected files from both a and b
Below is my code for download.php
<?php
include 'dbfunctions.php';
if (!$link) {
die(mysqli_error($link));
}
$sql="SELECT id, Font_Name, Font_Family
FROM font";
$result = mysqli_query($link, $sql) or die(mysqli_error($link));
while($row = mysqli_fetch_array($result)){
$Font_Family = $row['Font_Family'];
$a = file_get_contents('./a.txt');
$file_dir = file_get_contents('./font_path.ini');
$path = $file_dir.$Font_Family.$a;
$error = ""; //error holder
if(isset($_POST['createpdf']))
{
$Font_Family = $_POST['Font_Family'];
}
$file_folder = $path;// folder to load files
if(extension_loaded('zip'))
{
// Checking ZIP extension is available
if(isset($_POST['files']) and count($_POST['files']) > 0)
{
// Checking files are selected
$zip = new ZipArchive(); // Load zip library
$zip_name = time().".zip"; // Zip name
if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE)
{
// Opening zip file to load files
$error .= "* Sorry ZIP creation failed at this time";
}
foreach($_POST['files'] as $file)
{
$zip->addFile($file_folder.$file,pathinfo($file,PATHINFO_BASENAME));
readfile($path);
}
$zip->close();
if(file_exists($zip_name))
{
// push to download the zip
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$zip_name.'"');
readfile($zip_name);
// remove zip file is exists in temp path
unlink($zip_name);
}
}
else
$error .= "* Please select file to zip ";
}
else
$error .= "* You dont have ZIP extension";
}
?>
fontpath.ini is c:\fonts\
a is just \ since php gives me problem when I just write \
Font_Family is the different folder name inside c:\fonts\
so the path is like C:\fonts(whichever folder name here)\
You could take each font, regardless of the directory, and copy it to a temp dir, say, like, C:/fonts/temp/cartID/. You could then zip that directory of fonts (some from /fonts/a and some from /fonts/b) and provide the download. You then would need to garbage collect, that is, delete the temp cartID dir.
Just my 2ยข

I have tried outputting $zip object and got following response:
ZipArchive Object ( [status] => 0 [statusSys] => 0 [numFiles] => 12 [filename] => /var/www/bigb/ajax/images_24-12-2012.zip [comment] => )
Status Zero explains there were no errors while creating zip (reference: http://www.php.net/manual/en/zip.constants.php)
I have referred posts:
1) Download all images from a single directory of a website
2) How to create a zip file using php and delete it after user downloads it?
3) http://www.9lessons.info/2012/06/creating-zip-file-with-php.html
Third one helped me the most and in the other 2 i was getting status as 23.
Issue: I am able to create a zip & no issue downloading it but when i open the zip i don't see any files inside but zip has memory in mbs.
Please Help me out...
Update: Error 23 occurs because of print_r / echo and or trying to overwrite same file.
Update2: Issue solved. It was due to path in RecursiveDirectoryIterator (i.e ../uploads/) once i moved the code to main folder and changed the path to (uploads/) everything started working as it should be. Kudos!!!

I think the file path you are providing to $zip->addFile() is incorrect. You don't need to append anything to $file. Following will work:
foreach ($iterator as $file) {
$zip -> addFile($file);
}
In your case the $file will contain exact relative path of file like ../uploads/file.ext.
