Uploading a file from a URL

[moishy]

Hi all,
I have a Admin page (only for me, pass required) where I want be able to upload a file from the web, to my website.
I want to upload from a URL.
(I can't move_uploaded_f ile() because it's not in the $_FILES array.)


Can anybody please help me out on this?

Hi.

You may be able to use the file_get_conten ts function to do this.

It requires the allow_url_fopen directive to be enabled.

I don't get what I'm supposed to do with file_
get_contents(). ..

Here, say I have a variable containing a file address:
$file = "http://www.host.com/files/image123.jpg";

And I want to upload it to:
$target = "/files/";

How would I use file_get_conten ts() to do that?

Thanks guys, you are very helpful

You could, for example do:
[code=php]
<?php
$file = "URL to your file";
$target = "/path/to/your/save/dir/filename.ext";

if($contents = file_get_conten ts($file)) {
if(file_put_con tents($target, $contents)) {
echo "Your file has been uploaded!";
}
else {
echo "Failed to save the file to the target path";
}
}
else {
echo "Failed to get the file";
}
?>
[/code]

Thanks for your post!

It worked. But only when the Target path was set to the entire host directory!
i.e. /home/content/l/i/v/livingsidrah/html/ is considered the root folder (I use godaddy hosting)

Is there any workaround, that I won't need to type the entire directory?

You should be able to use a relative path. Something like:

path/to/relative/dir/file.ext

Didn't work for me:

PHP file is located here:
ROOT/directory/file.php

Upload target is:
ROOT/directory/files/uploaded_file.e xt

I set $target to /files/uploaded_file.e xt but didn't work.

I had the same problem with file_exists()

If you use a / in front of a path, a Linux system will assume that is an absolute path, starting from the root directory.

If you want to set a relative path, that is; a path relative to the current directory, do not put a / in front of it.

For example:
[code=php]
# Lets assume your code is being executed from:
# /var/www/html/index.php

# An absolute path
$absolute = "/var/www/html/uploads/newfile.ext";

# A relative path
$relative = "uploads/newfile.ext";
