Hi guys.
I have following script from net and I do not have any chance to reach who made it.
In script I would like to change original file name to users name. User name stored in my users table inside uLogin column.
Could it be possible?
Thank you.
PHP Script:
<html>
<head>
<?php
if ($_SERVER['REQUEST_METHOD'] == "POST")
{
/* SUBMITTED INFORMATION - use what you need
* temporary filename (pointer): $imgfile
* original filename : $imgfile_name
* size of uploaded file : $imgfile_size
* mime-type of uploaded file : $imgfile_type
*/
/*== upload directory where the file will be stored
relative to where script is run ==*/
$uploaddir = "./avatar/";
/*== get file extension (fn at bottom of script) ==*/
/*== checks to see if image file, if not do not allow upload ==*/
$pext = getFileExtension($imgfile_name);
$pext = strtolower($pext);
if (($pext != "jpg") && ($pext != "jpeg"))
{
print "<h1>ERROR</h1>Image Extension Unknown.<br>";
print "<p>Please upload only a JPEG image with the extension .jpg or .jpeg ONLY<br><br>";
print "The file you uploaded had the following extension: $pext</p>\n";
/*== delete uploaded file ==*/
unlink($imgfile);
exit();
}
//-- RE-SIZING UPLOADED IMAGE
/*== only resize if the image is larger than 250 x 200 ==*/
$imgsize = GetImageSize($imgfile);
/*== check size 0=width, 1=height ==*/
if (($imgsize[0] > 250) || ($imgsize[1] > 200))
{
/*== temp image file -- use "tempnam()" to generate the temp
file name. This is done so if multiple people access the
script at once they won't ruin each other's temp file ==*/
$tmpimg = tempnam("/tmp", "MKUP");
/*== RESIZE PROCESS
1. decompress jpeg image to pnm file (a raw image type)
2. scale pnm image
3. compress pnm file to jpeg image
==*/
/*== Step 1: djpeg decompresses jpeg to pnm ==*/
system("djpeg $imgfile >$tmpimg");
/*== Steps 2&3: scale image using pnmscale and then
pipe into cjpeg to output jpeg file ==*/
system("pnmscale -xy 250 200 $tmpimg | cjpeg -smoo 10 -qual 50 >$imgfile");
/*== remove temp image ==*/
unlink($tmpimg);
}
/*== setup final file location and name ==*/
/*== change spaces to underscores in filename ==*/
$final_filename = str_replace(" ", "_", $imgfile_name);
$newfile = $uploaddir . "/$final_filename";
/*== do extra security check to prevent malicious abuse==*/
if (is_uploaded_file($imgfile))
{
/*== move file to proper directory ==*/
if (!copy($imgfile,"$newfile"))
{
/*== if an error occurs the file could not
be written, read or possibly does not exist ==*/
print "Error Uploading File.";
exit();
}
}
/*== delete the temporary uploaded file ==*/
unlink($imgfile);
print("<img src=\"$final_filename\">");
/*== DO WHATEVER ELSE YOU WANT
SUCH AS INSERT DATA INTO A DATABASE ==*/
