i have look at the tutorial from http://www.codewalkers.com/c/a/File-Manipulation-Code/ZIP-File-Maker/

 

i dont understand what they want me to do with this line

 

$filedata = "(read your file into $filedata)";

 

do they just want me to put in the location of the file i want to zip?

ok i have changed tutorial and now i am using the one http://www.web-development-blog.com/archives/tutorial-create-a-zip-file-from-folders-on-the-fly/ as it accomodates folders being zipped.

 

I am getting the error

 

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /homepages/12/d214897219/htdocs/rubberduckiee/admin/FTP/code/zip.php on line 11

 

this is the code i am using

 

<?php
include ('zip.php'); 

$createZip = new createDirZip;
$createZip->addDirectory(‘adam/’);
$createZip->get_files_from_folder(‘footer/’, ‘adam/’);

$fileName = ‘tmp/archive.zip’;
$fd = fopen ($fileName, ‘wb’);
$out = fwrite ($fd, $createZip->getZippedfile());
fclose ($fd);

$createZip->forceDownload($fileName);
@unlink($fileName);


?>

 

and line 11

 

fclose ($fd);

You're using quotes wrong

 

Wrong

$createZip->get_files_from_folder(‘footer/’, ‘adam/’);

 

Good

 

$createZip->get_files_from_folder('footer/', 'adam/');

 

(They're the ones next to Enter key on standard US layout keyboard)

i have realised the error is point to somehting with the extended class written by the guy who created the tutorial. Any ideas?

 

class createDirZip extends createZip {

  function get_files_from_folder($directory, $put_into) {
    if ($handle = opendir($directory)) {
      while (false !== ($file = readdir($handle))) {
        if (is_file($directory.$file)) {
          $fileContents = file_get_contents($directory.$file);
          $this->addFile($fileContents, $put_into.$file);
        } elseif ($file != '.' and $file != '..' and is_dir($directory.$file)) {
          $this->addDirectory($put_into.$file.'/');
          $this->get_files_from_folder($directory.$file.'/', $put_into.$file.'/');
        }
      }
    }
    closedir($handle);
  }
}

a couple things I see... first I would suggest taking out the spaces right after fopen and fwrite i.e. fopen ( -> fopen(. Also I would suggest try using an absolute path for your folders i.e. /var/www/html/adam other then that idk.

 

I have a couple ideas.. first one being that code looks so sloppy.  Second either edit that code yourself.. or idk get a new one?? idk too tired to completely think lol

        }
      }
    }
    closedir($handle);
  }
}

 

there are no syntax errors in that code. post the exact error again, and the contents of the file it says the error is in. what i'm getting at is, is there more to the zip.php file then what you posted above?

how i call on zip.php, file called test_zip.php

 

<?php

$createZip = new createDirZip;
$createZip->addDirectory('themes/');
$createZip->get_files_from_folder('footer/', 'themes/');


$fileName = ‘tmp/archive.zip’;
$fd = fopen ($fileName, ‘wb’);
$out = fwrite ($fd, $createZip->getZippedfile());
fclose ($fd);

$createZip->forceDownload($fileName);
@unlink($fileName);
?>
