File Upload Replace

[Jaybirddesigns]

I have a script that uploads fine, but i want it to replace the curent file in that specific Dir. Not however make a temp name. So basiclly if i upload pic1.jpg it will replace pic1.jpg, not make it 000123pic1.jpg

Any Ideas?

Script

PHP Code:

<?php 
session_start(); 
if(!isset($_POST['upload'])) { 
echo ' 
<form name="upload" enctype="multipart/form-data" method="POST" action="'.$_SERVER['REQUEST_URI'].'"> 
<input type="file" name="file" size="13" value=""> 
<br /><input type="submit" name="upload" value="Upload"> 
</form> 
'; 
} else { 
$yourdomain = 'http://www.jaybirdfolio.com/'; 
$uploaddir = 'images/'; 
$filename = $_FILES['file']['name']; 
$filesize = $_FILES['file']['size']; 
if($filesize > '5000000') { 
echo "Way too big!!"; 
} else { 
move_uploaded_file("$uploaddir$filename"); 
echo "Successful.<br /><b>URL: </b><textarea rows='1' cols='13'>".$yourdomain.$uploaddir.$date_file.$filename."</textarea>"; 
} 
  } 
?>

I actually wrote this script for images, but you can edit it for any files.
(just change the extensions!)

I also got rid of all the syleing (I built it for a img script hosting site, view here)

But, here's the script:
Be sure to name the file: index.php

PHP Code:

<?
error_reporting(7);
// Max size PER picture in KB, not bytes for simplicity!
$max_file_size="5120";

// Max size for all picutres COMBINED in KB, not bytes for simplicity!
$max_combined_size="25600";

//How many file uploads do you want to allow at a time?
$file_uploads="5";

//The name of the uploader..
$websitename="Your name here";

// Use random file names? true=yes (recommended), false=use original file name. Random names will help prevent overwritting of existing files!
$random_name= true;

// Please keep the array structure.
$allow_types=array("jpg", "jpeg", "gif", "png");

// Path to files folder. If this fails use $fullpath below. With trailing slash
$folder="path/to/images/";

// Full url to where files are stored. With Trailing Slash
$full_url="http://yoururl.com/path/to/images/";

// Only use this variable if you wish to use full server paths. Otherwise leave this empty! With trailing slash
$fullpath="/http/yoururl.com/full/path/to/images/";

//Use this only if you want to password protect your uploads.
//Not recommended for free picture hosting sites)
$password="";

Wow very cool how long did it take you to write all that? Can't wait to try. It doesn't have to be index does it? just as long as it has the php extension right? it could be upload.php

[Jaybirddesigns]

Uploads Great thanks for the cool uploader. One thing though, I want the uploader to be able to replace the exsisting file in that specific directory. I replaced false under random file names but i get the error saying:

"The file: mccain.jpg exists on this server, please rename your file.
Your file(s) were not uploaded."

Is there a way around this?

Or do i need to right a script that removes the file. I beleive somthing like unset.

Thanks,

Jason

[pezboy45]

So, you want something like this:
http://img.dahoster.org/
(make an account)
It allows you to upload an image, and then upload it again, but replace it with a new one.
Hmm.
Well, I don't know how to do that.
But, I'm sure you could find what your looking for on:
http://hotscripts.com

[ishkey]

see if this one works

[Jaybirddesigns]

Great! Can't wait to try.

[Jaybirddesigns]

Were do I put the Dir to where i want my upload to be.

function setUploadLocation($dir){
$this->uploadLocation = $dir;
}

Do i put it here like this?

function setUploadLocation(http://www.domain.com/images){
$this->uploadLocation = $dir;
}

[ishkey]

try this one instead it is just for jpgs
it will create 3 directories for you - the code is easy to see
original
normal
thumbnail

you may have trouble with the .htaccess file - either mod it or leave it out
remember uploading threw http is slower. plus the program is doing alot. you can reload with the same name.
