Is this what you need?

Actually, FTP is not used for this...

Files are uploaded via standard POST method, and PHP has built-in support for handling file uploads: http://www.php.net/manual/en/features.file-upload.php

Ok, i get the thing to work, but there is only one problem:

The file exist on the server and i can access the file via ftp, but i cannot view the image in the browser.
When i download the image via ftp and view it, everything is correct.

Did i miss something?

Here is my code:

echo "<form enctype=\"multipart/form-data\" name=\"form\" action=\"admin.php?sect=4\" method=\"post\">\n";

echo "<input type=\"hidden\" name=\"MAX_FILE_SIZE\" value=\"1000000\" />\n";

echo "t.jpg: <input size=\"50\" name=\"userfile[]\" type=\"file\" /><br />\n";

echo "s.jpg: <input size=\"50\" name=\"userfile[]\" type=\"file\" /><br />\n";

echo "</form>";

and later in the script:

$RootPath = getcwd();

if (!move_uploaded_file($HTTP_POST_FILES['userfile']['tmp_name'][0],$RootPath."/snapshot/".$HTTP_POST_FILES['userfile']['name'][0])) {echo "there is something wrong";}

if (!move_uploaded_file($HTTP_POST_FILES['userfile']['tmp_name'][1],$RootPath."/snapshot/".$HTTP_POST_FILES['userfile']['name'][1])) {echo "there is something wrong";}

Try this. This is something we're using for a content management system that allows us to upload the photos, PDFs, and stuff for related articles. Change $the_path accordingly, and change the two instances of "mydomain.com" to whatever applies.

This will allow you to limit by file type, file size, file dimensions (images), etc, as well as the ability to direct files to directories based on type. It will show a resulting link with file size info.

<?php

$my_max_file_size = "102400"; # in bytes
$image_max_width = "468"; # in pixels

I looked at your code, and tried to modify my, but it still didn't work.

BTW: i get a 403 error.

I think i have to change the setting of the file, that every user can access it.

Run phpinfo and see what the open_basedir setting is. I verified the script works fine if you change these lines
$the_path = "/full/server/path/to/upload/dir";
$url_path = "http://www.mydomain.com/up/";
print("<b>Link:</b> <a href=\"http://www.mydomain.com/$type/$the_file_name\">$the_file_name</a> ($upload_file_size kb)\n");

Change them to the correct settings. It works fine on PHP 4.0 and above, as long as the open_basedir setting isn't too restrictive.

Thanks for the script, i fixed it.

And I'm always looking for ways to optimize/enhance this. So if anyone has suggestions....

Well, don't use global variables. Here is a good article about that: http://zend.com/zend/art/art-oertli.php

Ohh, i filtered out the lines i need:
copy($the_file, $the_path . "/" . $the_file_name));
rename ("$the_path/$the_file_name", "$DOCUMENT_ROOT/$type/$the_file_name");

Why doesn't work the code i mentioned above?

not really relevant in this context.
The global scope issues mentioned in that article mainly refers to security issues related toisession variables and secure areas of sites. globals are still useful in this method.

pugz the main thing I would do here is try to wrap this up into a class for portability.

The other thing is just an ease of coding tip. When printing out a bunch of HTML (in particular with few echoed variables) it's easier to temporarily dump out of PHP parsing mode (even in the middle of a function)

function form($error=false) {



global $PHP_SELF,$my_max_file_size;



if ($error) print $error . "<br /><br />";



?>

<form enctype="multipart/form-data" action="<?=  $PHP_SELF ?>" method="post">

<input type="hidden" name="MAX_FILE_SIZE" value="<?=  $my_max_file_size  ?>" />

<input type="hidden" name="task" value="upload" />

Upload a file

<br />NOTE: Max file size is <?= ($my_max_file_size / 1024) ?>KB

<br /><input name="the_file" type="file" size="50" /><br />

<input type="submit" value="Upload" />

</form>

<?

} # END form

This will work fine.
I'll muck with it a bit see if I can make it a class.

Pugz: i tried to use your script, and i get the following message:
"Parse error: parse error in /home/jamesowe/public_html/sigs/index.php on line 130"

Line 130 is:
if ($type == "gif"

Remove space between &#124; &#124; (it should be written like this &#124;&#124; )...

A little more on how this script works....

I'm using it for a CMS setup. The site has a different folder for each type of file. So, .jpg and .gif files are considered "photos", and go into /photos. .doc files go to /doc, and .pdf files go to /pdf. That's why I'm checking the file types and piping the type to the COPY part.

It works pretty well. I'll probably start cleaning it up and see if I can't get the same results in less lines. I'm sure Mr. Max could do this same thing in two lines of code....

copy...(shudders)

"No one's going to give you a map; you've got to walk your own path." - Hot Ice Hilda, Outlaw Star.

Instead of making comments like that, why don't you actually CONTRIBUTE something.

That's what these forums are for.

Okay, fine:

copy() is the devil. Use the FTP functions instead.

Why? Most servers have copy() disabled; simply because it's part of the UNIX control set; which includes exec() and a bunch of other functions.

And most of those are disabled to prevent people from mucking around with the servers.

The FTP functions are a lot nicer and easier to use; because you can reuse the code any time you want to upload something.

Well, the copy() command has worked quite well in our CMS system, hence the posting of the code.

Perhaps you'd like to post a script that does everything that the above script does, only using FTP?

Very well:

Put this up at the top somewhere:

$conn_id = ftp_connect(/*Your FTP server*/);
$login_result = ftp_login($conn_id,/*Your FTP username*/,/*Your FTP password*/);

And put this were you want the transfer to occur:

if((!$conn_id) &#0124; &#0124; (!$login_result))
{
echo "FTP connection has failed!";
}else{
/*You can put this line in place of copy()*/
$upload = ftp_put($conn_id,/*New File Name*/,/*Pointer To Old File*/,FTP_BINARY);
}

And this at the bottom:

ftp_quit($conn_id);

Hmm, I've just tried this script out at my Dreamhost accont, and I keep getting the "something barfed" message, I seem to remember a notice saying that certain rsiky functions might have been disabled at dreasmhost, could copy() be amongst them? I'll go look now, and if this is the case, try the FTP script offered here, let you know how it works out!

Your pal, -doc-

Hmm, seems like maybe a different problem, phpinfo() tells me this...

Disabled functions: dl,exec,system,passthru,chgrp,chown,touch,symlink,link

I've got all of my paths right, and the directory is 777 (something that makes me just a wee bit uncomfortable, heh), damn thing should be working now! Hrmph.

Hmm, what user is PHP supposed to be running as? I seem to remember that Dreamhost said it would run as me instead of "nobody", but reading phpinfo() it seems to be HTTP_ENV_VARS["USER"] = root - not sure if *that* is too safe, heh.

Your pal, -doc-

OK, just for any other Dreamhost users here, Dreamhost is now running an additional PHP processor called "PHP-CGI", which allows you to run PHP with the user as *you* instead of as nobody. You need to alter the extension of your PHP files to ".pcgi", but they then work just as you'd expect them too. (The only difference is the uploaded files now belong to me, and I can do what I want to them using FTP or telnet, cool.)

Your pal, -doc-

Interesting....the biggest problems I've run into while working on this is the open_basedir problem. That's quickly resolved with an edit of the .conf file....

Obviously, I could make this much more feature packed, with CHOWNing files to your user name, etc....

Interesting...(heads back to the laboratory to hack some more)

The first upload script I wrote, I used copy().

And every time I tried to upload something, I got a "File Not Found" error. I checked the CHMOD repeatedly, used echos to see what was being produced, etc. And there was absolutely nothing wrong.

Replacing that with the FTP functions caused it to work 100%.

LS,

Sorry to jump in right here in the middle (just registered) but i had to say this...

I usually have a idea of what i want and roam the php.net/manuals for the exact functions. Like http://www.php.net/move_uploaded_file function (i found it overwrites files, so you could do a if(file_exists) before that... also i found that you (might) have to check filenames. Mac (and Windows?) allow certain characters in filenames which *nixes might not like (*,/,

tr909 -

this is actually a bastardized code. I've been cleaning it up and doing some other stuff with it. I *think* we are going to use it as part of the CMS for the new GurusNetwork site. In the posted example, I use the extensions to determine where I need to store the file, as well as making sure I'm only uploading what I should be uploading (it's part of a CMS system, and it has some "idiot checks" built in).

I'll get a cleaner version up soon.

sorry for being a bit late, but i also tried the same thing doc did.
i have problems with running that on dreamhost, and to be honest...i am a n00b in PHP and i don't exactly understand what to do.
first of all....can anyone help me with the path and the url? whats the difference there? i entered http://www.thespacebetweenus.com/test in the URLpath and well....what do i have to enter in the first one where it says "the full server url" ? ain't that the same? sorry for that stupid question

your fullpath (on DH) would be something like:

/home/username/thespacebetweenus.com/test/

replace username with yours of course

Jason

i love you

give us kisses

Jason
