Please, paste here a reduction code of your controller and view.[/quote]
It is a little more complicated, is Ajax through jQuery when a form is submitted.

But for the test I'm not using the $_POST data sent for the ajax request. Just to be sure that the error is not generated for the data sent

js:

Code:

$('.form_class').live('submit', function(eve){
    eve.preventDefault();
          
    //console.log( $(this).serialize() );
        $.post(base_url + 'download/zip_files' , $(this).serialize() , function(html){
                
        });
    });

php:

Code:

function zip_files()
{
//NOT USING THE $_POST DATA
$this->load->library('zip');

$path = 'images/myImage.jpg';
//$this->firephp->log( $path  );
$this->zip->read_file($path);

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

}

Have you tried to test it without ajax?

Code:

echo anchor('download/zip_files','download');

I tried http:localhost/mySite/download/zip_files
but get an error, something about MIME type:

ErrorException [ Warning ]: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/muestra3/application/controllers/download.php:26)

header('Content-Type: "'.$mime.'"');

You echo something before download the zip!

Is the zip_files function exactly this?

Code:

function zip_files()
{
//NOT USING THE $_POST DATA
$this->load->library('zip');

$path = 'images/myImage.jpg';
//$this->firephp->log( $path  );
$this->zip->read_file($path);

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

}

Do you send some header in your controller constructor?

You don't need ajax. You can remove the jquery script!
You can call download/zip_files directly.
Set the action form to 'download/zip_files'.
