Hi guys!
I've written a js class for Google Gears multiple file uploading, and a corresponding file upload script.
Thing is, gears doesn't send the file via a 'regular' file upload field, but rather as a stream of bytes, ready to be processed.
Below you see my code, but I want to convert it to a CI lib or helper or so, in a way that I can use CI's image manipulation lib to save the images in different sizes and so on.
Anybody knows enough of CI library's to help me out?
Thanks in advance!
Code:
<?php
// function to catch the error and send it along with a 500 header
function report_error($title, $msg) {
header("HTTP/1.1 500 $title");
echo $msg;
exit;
}
// generate a unique md5'ed name for the file
function uid() {
mt_srand((double)microtime()*1000000);
$token = mt_rand(1, mt_getrandmax());
$uid = uniqid(md5($token), true);
if($uid != false && $uid != '' && $uid != NULL) {
$uid30 = md5($uid);
} else {
$uid30 = 'error';
}
return $uid30;
}
// define directory
define('UPLOAD_DIRECTORY', 'upload/');
// check if writeable
if (!is_writeable(UPLOAD_DIRECTORY)) {
report_error("System error", "Dir not writeable");
}
$filename = '';
// fetch the headers
$headers = array_change_key_case(getallheaders(), CASE_LOWER);
if (!isset($headers['content-disposition']) || !preg_match('~filename="([a-z0-9_\. \-]+)"$~i', $headers['content-disposition'], $matches)) {
// if it misses the content-disposition header or if it isn't filled with the file's info, go error.
report_error('System error', 'No file info: ' . $headers['content-disposition']);
}
// check the file name
$filename = basename($matches[1]);
$nameArr = explode('.', $filename);
$total = count($nameArr);
$ext = $nameArr[$total - 1];
$finalname = uid() . '.' . $ext;
// write the file (it's still empty)
$fp_dst = @fopen(UPLOAD_DIRECTORY . $finalname, 'w');
// write error
if(!$fp_dst) {
report_error("System error", "Couldn't write file");
}
// the file stream
$fp_src = fopen('php://input', 'r');
$length = 0;
// do things below for as long as the stream isn't to its end
while(!feof($fp_src)) {
// read the bytes in php://input
$data = fread($fp_src, 1024);
// catch the length and add it to the bytes read before
$length += strlen($data);
// write the bytes into the file we created earlier
fwrite($fp_dst, $data);
}
// close the file and the byte stream
fclose($fp_dst);
fclose($fp_src);
echo "<a >Success!</a>";
?>
