Topic: Check for existing file on server
In order for the chevereto script to check for existing files on a server (as to not overwrite them) some changes have to be made.
First off, the image uploaded needs to be placed in a tmp folder, so it can be checked against the other images on the server.
Here is an explanation and some examples of the code
http://us2.php.net/manual/en/function.file-exists.php
I would like to see the script checking for existing files, and automatically rename them if a file exists..
Explanation and some samples
http://ua.php.net/manual/en/function.rename.php
sample code:
<?php
// Name of the uploaded file
$name = $_FILES['uploadedFile']['name'];
// Random 25 chars+nums . . .
$your_25_digit_code = substr(md5(rand(0,9999)), 17, 25);
// Get the file apart by ., so the 25 chars can be added before the extension
$temp_arr = explode(".", $name);
// Default it
$original_name = '';
// Make sure the file isn't something like
// image.something.whatever.hi.hello.what.s.up.png
// Minus 2 because it would come out to
// (file_name).(random_chars).(extension),
// with this it comes out to (file_name)(random_chars).(extension)
for ($x = 0; $x < count($temp_arr)-2; $x++) {
// Add to it
$original_name .= $temp_arr[$x] . '.';
}
// The new file name
$new_file = $original_name . $temp_arr[$x] . $your_25_digit_code . '.' . $temp_arr[$x+1];
$tempFile = $_FILES['uploadedFile']['tmp_name'];
$destination = "C:\\ImageHosting\\" . $new_file;
copy($tempFile, $destination);
copy($_FILES['uploadedFile']['tmp_name'],
$_FILES['uploadedFile']['name']);Last edited by wout000 (2009-06-10 05:01:48)
