How to zip 2 images files and download the zip file?

[eluser]chefnelone[/eluser]
Hello,

I found this in the user guide to zip an existing file, works fine but just with one file.

Code:

$path = '/path/to/photo.jpg';

$this->zip->read_file($path);

$this->zip->download('my_backup.zip');

I need to zip 2 files and then download the zip file. Something like ( the code below is not working.. just to give an idea of what I need to do)

Code:

$path1 = '/path/to/photo.jpg';
$path2 = '/path/to/photo2.jpg';

$data = array($path1, $path2);

$this->zip->read_file( $data );

$this->zip->download('my_backup.zip');  // this zip file contains both photos

thanks

Hi chefnelone,

you can use $this->zip->read_dir() that permits you to compress a folder (and its contents) that already exists somewhere on your server.

Code:

$path = '/path/to/your/directory/'; //path where are stored your two files

$this->zip->read_dir($path);

// Download the file to your desktop. Name it "my_backup.zip"
$this->zip->download('my_backup.zip');

I see, but the folder containing the images has another images that I don't want to include in the zip.
I think I'll need to create a folder, move the images to this folder, then use $this->zip->read_dir($path); and delete the folder after.

I believe that de Zip class should include a function to do this task this simpler...

Code:

$path = 'path/to/file1';

$this->zip->read_file($path);

$path = 'path/to/file2';

$this->zip->read_file($path);

// Download the file to your desktop. Name it "my_backup.zip"
$this->zip->download('my_backup.zip');

Rare, suddendly the zip class stop working

image

Code:

function zip_files()
{
  $this->load->library('zip');

  $path = '/images/myImage.jpg';

  $this->zip->read_file($path);

  // Download the file to your desktop. Name it "my_backup.zip"
  $this->zip->download('my_backup.zip');

}

Something to do with my server (I'm on localhost running on MAMP)???

Don't echo nothing before zip file!

nothing just the output through Firebug you can see in the image... rare it was working fine, maybe my server???

I have Firephp to output whatever info from the function zip_files, if this helps...

The rare character you see is the zip file output in the debug firephp var.
Probably is a buffering output problem. Try do disable firephp or check if the directive output_buffering is On in your php.ini conf file and set it to Off.

output_buffering is set to Off
I disabled Firephp

I also restart my server (MAMP)

Do you call zip_files function from an anchor?
Please, paste here a reduction code of your controller and view.
