Upload from Link Instead?

[Warptweet]

Here is the BASE for my uploader code, which will be later heavily edited. It works perfectly, absolutely no problem. Although, how would I upload a file through it's direct source link on the internet OR from files on your computer?

 

Here is my code. For this code, you can only upload from the location on your COMPUTER, but I need it to do that, AND be able to upload from a link on the internet. Thanks for any help!

 

<?php

function generate_rand($l){
$c= "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
srand((double)microtime()*1000000);
for($i=0; $i<$l; $i++)
{
$rand.= $c[rand()%strlen($c)];
}
return $rand;
}

$uploaddir = "./";
$maxfilesize = 1048576; //1 megabyte
$filename = $_FILES['file']['name'];
$filesize = $_FILES['file']['size'];
$filetmpname = $_FILES['file']['tmp_name'];
$valid = array (".jpg",".gif",".png");
if ($filename) {
$error = "";
if ($filesize == 0) {
$error .= "The submitted file was invalid.<br />";
}
$type = strtolower(strstr($filename, '.'));
if (!in_array($type, $valid)) {
$error .= "The submitted file was of invalid type.<br />";
}
if ($filesize>$maxfilesize) {
$error .= "The submitted file was larger than a Megabyte.<br />";
}
$randnum = generate_rand(10);
$randnum .= $type;
$file_exists = true;
while ($file_exists) {
if (file_exists("$uploaddir$randnum")) {
$randnum = generate_rand(10);
$randnum .= $type;
}else{
$file_exists = false;
}
}
if ($error == "") {
if (move_uploaded_file($filetmpname, "$uploaddir$randnum")) {
chmod("$uploaddir$randnum", 0644);
echo "Your file was successfully uploaded!<br />";
echo "<a href='".$uploaddir$randnum."'>Click here to go to your upload!</a>";
}
else
{
echo "Your file could not be uploaded.";
} 
}else{
echo $error;
}
}else{
echo "No file was uploaded";
}
?>

You can use copy to copy files from a url to your server providing url wrappers are enabled in your configuration.

Where is the code that calls the

function generate_rand($l)

?

[Warptweet]

It's here

 

$randnum = generate_rand(10);

 

Right below the "You entered a file above 1 Megabyte" error message in the code.

There is a syntax in your code.

echo "Testing output would not show up";
