ok i have searched this site as well as 4 others looking for help on this. I am trying to download an entire folder based on a username that is input into a text box. i want to zip the file first as it will be holding images. then save the zipped file to my local machine. the current script i have is put together from 2 other scripts that i found online, sorry i dont remember now where exactly i got them from as i have changed them numerous times and i have about 6 variations now.

the script i have does exactly what i want with 2 exceptions.

1. it saves the zipped file to the server not to my local machine

2. it only added the files that i hard code into the zip.php script. not the folder that i put into the text box.

 

this is the script im using. i added the headers to force the dialog box to pop up so i can save it where i want to, but if anyone knows a better way i would be most grateful.

<?php
$files_to_zip = array(
    'upload_test/user/2009-07-01-214005Logo.jpg',
    'upload_test/user/2009-07-01-215314orange_bg.gif',

);
//if true, good; if false, zip creation failed
$result = create_zip($files_to_zip,'test.zip');

/* creates a compressed zip file */
function create_zip($files = array(),$destination = '',$overwrite = false) {
    //if the zip file already exists and overwrite is false, return false
    if(file_exists($destination) && !$overwrite) { return false; }
    //vars
    $valid_files = array();
    //if files were passed in...
    if(is_array($files)) {
        //cycle through each file
        foreach($files as $file) {
            //make sure the file exists
            if(file_exists($file)) {
                $valid_files[] = $file;
            }
        }
    }
    //if we have good files...
    if(count($valid_files)) {
        //create the archive
        $zip = new ZipArchive();
        if($zip->open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) {
            return false;
        }
        //add the files
        foreach($valid_files as $file) {
            $zip->addFile($file,$file);
        }
        //debug
        //echo 'The zip archive contains ',$zip->numFiles,' files with a status of ',$zip->status;
        //close the zip -- done!
        $zip->close();
         
        //check to make sure the file exists
        return file_exists($destination);
    }
    else
    {
        return false;
    }
}
  $buffer = file_get_contents($file);
