Allow Anyone To Upload Files To a Folder in Your Dropbox Account

I’m getting a “Cannot create temporary directory!” error when uploading a document.

My webhost supports php. I have several working php pages. I created the folder in Dropbox first, then I updated lines 48 and 71 in index.php.

Will give it a try. And by the way this theme looks much similar to labnol. Have you bought this from Amit?

Hey can anyone help me with the error, i run the script and get this:

Error: Cannot execute request: Failed to connect to http://www.dropbox.com IP number 1: Permission denied

A great place to share stuff to your friend =)

Any way to password protect or require a code so that not ANYONE can upload?

Any way to allow the selection of multiple files?

I’m *already* able to get files from (and share with) invited friends — how is this different?

I get the error:
Parse error: syntax error, unexpected ‘{‘ in /blah/blah/dropbox/index.php on line 15

The reason is my host (1and1) defaults to PHP4. To enable PHP5, I had to create a “.htaccess” file in the same directory as the Stuff My Dropbox php files with a single line of:

AddType x-mapp-php5 .php

Now it works like a champ

OK, for all of you seeing the “Parse error: syntax error, unexpected ‘{‘” error, your server is running PHP4, and the exception syntax used in the script requires PHP5.

Hi Amit,

I have made some (security-)changes to your script. If you want reply to my email.

Regards,

Thorsten

I created the folder on Dropbox but this is the error I receive. The shared folder name is ‘share’. Could that be a problem?

Error: Remote directory must be a string, is NULL instead.

Is anyone else having issues uploading files over a couple of MB? It works perfectly with small files, but any MP3′s or zip files its uploads and then errors or just uploads and never appears in dropbox.

@Gary: PHP has a limit on maximal upload size I believe. It needs to be corrected in the php.ini of your provider (normally you don’t have access to it :-P) or set in code with:

ini_set(‘upload_max_filesize’, ’20M’);
ini_set(‘post_max_size’, ’20M’);

@TC: your line 75 in index.php should look like this:

I have the same problem as yoh and Cary; can’t create temporary directory. Anyone got a clue?

@Oskar: are you on a hosted webserver? Normally you should be allowed to write into the /tmp-directory.

@Oskar: Thanks I forgot to modify the post_max_size. I’m all good now. Much appreciated.

i’m on godaddy economy hosting. it says hosts php4 and php5, but my page still loads up blank?

I have modified the script to make it a bit more secure and added a dropdown to choose between different directories. You can get my du_v3.rar here:

http://dropbox.kingofcomedy.de/

This is an awesome script!

I took the password protection from this blog and the cool graphics from http://www.addictivetips.com/internet-tips/allow-anyone-to-upload-files-to-your-dropbox-folder/ and combined them into my own: http://dl.dropbox.com/u/8328259/dropbox.zip

I also put all the configuration stuff AT THE TOP and I included the cert from the site for those people that are getting cert errors.

Finally, if you are on a hosting provider, you are limited by upload_max_filesize and post_max_filesize which are set in php.ini.

Thanks all!

Any ideas what’s causing the “Cannot create temporary directory!” error? The error is written into the php code so it must be in anticipation of a possible scenario. What’s lacking on the server side?

I have optimized the design of my script with the background-image from addictivetips.com too. My version #4 (incl. reduced code) is available here: http://dropbox.kingofcomedy.de/ :)

see this https://www.cliqcliq.com/support/quickpic/#web-app-integration

i want upload all files, not only images, i want upload all files *.*

I keep getting this error.

Warning: mkdir() [function.mkdir]: No such file or directory in D:\Hosting\2694903\html\upload\index.php on line 37
Error: Cannot create temporary directory!

I did everything correctly. I have my site hosted on Godaddy.com, standard economy hosting. If anybody can help, let me know.

Here’s my site: http://uploads.blueicegraphix.com

Is there any way to stop people from uploading large files or some type of files?

This is great! My clients are always trying to burn files to CD and send them via snail mail – and are not open to the idea of learning anything “too technical-ish” .. this is a perfect solution!

All,

I took my code and put it on googlecode as a project. You can see it here:

http://code.google.com/p/stuffmydropbox/

Furthermore, I have a wiki page that answers some of the problems people are having here (although the version on the google code project is different than the one above, so I can’t answer all problems on the web page):

http://code.google.com/p/stuffmydropbox/wiki/Troubleshooting

For example, it shows how to fix the SSL problem and the mkdir problem.

Specifically: SSL issue:
This occurs using the version of the “stuffmydropbox” that does web scraping. You’ll have to download the cert from https://www.dropbox.com and then upload the cert to your web host and then add this line right before the code uploads the file:

$uploader->setCaCertificateFile(‘/path/to/uploaded/cert’);

be sure to change the path to the uploaded cert

The mkdir problem means that the web server can’t make the directory. You’ll want to hard code in the directory it should make (it is trying to create on in ‘/tmp’ but you don’t have permission to /tmp on every web host. Find the /tmp line and change it to a path that exists on your web server or a path that you know you have permission to.

—-

It is hard to know what version everyone is using… however, I should be able to answer people’s questions if they use the version from google coede.

Colorado Teche, I can’t seem to be able to view your website, it says that your pages are forbidden.

I need answers to my questions :D

I tried following the suggestion of making a static webpage using dropbox, but it seems that the link to page with a .php extension simply downloads it, whereas if I use .html, it works, but then again the dropbox uploader is in .php, I tried the .htaccess way, but I can’t seem to make it work,
So I just looked for a free php hosting site, and I have problems with the mkdir() I followed what you said on hardcoding it and changing /tmp to something I can access, but I’m not sure if I’m doing it the right way, can you have a step by step instruction? What I did was I made a new directory, then changed the code of instead having /tmp, I changed it to the name of the directory I made. I don’t think I’m doing it right :))

Help! :D

Hi, I couldn’t upload. I receive the following message:

Error: Cannot create temporary directory!

I’m using the new script with password, I modified the password, I modified the Dropbox username and password and I modified the name of the folder in the Dropbox.
Any idea? Thanks

Could you technically use this instead of dropbox a private FTP server?

Hi Steve,

to show the upload-progress is not possible, afaik, because PHP doesn’t know the real filesize while a file is being uploaded. And the PHP-Script doesn’t know if a file already exists, sorry. It would definitely be easier if the Dropbox-API could be accessed by everyone without registration.

Large files do not upload and I get no error. A 25MB file just seems to time out. I have increased the timeout on my server. The script is worthless if you can’t upload large files.

You can also automatically upload the scheduled WordPress Database backup files to your Dropbox: http://www.techtipsgeek.com/schedule-wordpress-database-backup-to-dropbox-account/10643/

Amit,

Yes. I’m getting it even on files as small as 2.7mb. Perhaps it’s a server timeout setting on my side of things?

Thanks for your help. Much appreciated.

Amit,

I did some poking around with Fiddler and discovered that the problem seems to be with my hosting provider. My web server fails to complete and the Dropbox servers continue to try to initiate connections which time out at about 30 seconds and then give a 504 result. That points to a problem with it not getting the response it needs from my web server that’s upstream. Tech support is looking into the problem now.

Just fyi, the largest file I could get to upload was only 1.7mb. A file 2.4mb failed.

Bottom line is that I don’t think this is something you can fix, but I appreciate the confirmation that 10mb+ video files will work with your solution.

Regards,

Doyle

There is now a free service based on this lovely script:

DROPitTOme – Securely receive files from anyone to your Dropbox.

Happy Dropboxing!

Does anyone get these errors?

Warning: preg_match_all() [function.preg-match-all]: Internal pcre_fullinfo() error -3 in /usr/local/www/upload/DropboxUploader.php on line 129

Warning: preg_match() [function.preg-match]: Internal pcre_fullinfo() error -3 in /usr/local/www/upload/DropboxUploader.php on line 139

This is a new install and I’ve been troubleshooting this for quite awhile and I haven’t come up with a solution. Googling only brings results of an issue a year ago when dropbox changed domains for where to upload to.

Hi

I made a website to help my university freind to collect information about our subjects.

I used your tool to change dropbox so everybody can upload but as Im not really good and pritty new to website design I used this free web page creator at webs.com.
I really need this dopbox to include on our page so peopel can easily uplod files but dont know how to do it.
If you could help me the whole Aberdeen university economic course would be greatfull to u :)

BEST REGARDS

i am using win 7 and xampp. please help me

1000 thanks you are great :)

Would there be any way to add a progress bar? I love this script and have been putting it to use a lot! The one complaint I have gotten is the people don’t know if it is doing anything until the file either uploads or fails.

Any help?

I am trying to create an upload page for my website that allows my students to input their first and last names, email address, and upload their projects to my dropbox, how would I go about doing this?

I’m using Thorsten’s V6 with one added slot each for a total of 5 files (or 5 links) per upload. It works great. I’d love to find a version that adds a text field to the form and uses the contents of that field to rename files (“text1.xxx, text2.xxx, text3.xxx”) after upload, but retains original filename extensions.

@Thorsten: That would be fantastic!

I only need one (required) text field for the whole form, the contents of which then becomes (or is pre-pended, but not appended) to the filename for each uploaded file in that batch (if replacing the original filename, it would need to also add sequential numbering to differentiate between files in that upload and keep filenames unique (text_1.xxx through text_5.xxx). If pre-pending, numbering would be unnecessary.) I’d like to preserve the original filename extensions, though.

I’m using this for uploads of images of prizes to be considered for inclusion in a charity auction. Users are volunteers gathering and submitting prizes. (The auction itself will run on an existing auction platform; this is just the prize-gathering phase). Prize info (except images) is submitted through a Google docs spreadsheet form, and images separately through this form. To help me match up images with their respective prize listing in the Google spreadsheet, users are are supposed to name image files with a descriptive word or phrase we’re calling the Prize Name, and include that in filenames for all files associated with that prize, but experience so far shows relying on users to do that is problematic.

Making this step more user-friendly will force filenames to be consistent and sortable and eliminate the possibility of unidentifiable images. My installation is at mmf-auction.org/images if you want to see it.

The more I think about it, replacing and numbering (rather than pre-pending) seems better; otherwise names could get pretty long and funky.

@Hilleary: ok, I have added an extra-field called “file-prefix” in my test-version. But what now? Can you give me an example of how the files should get renamed?

Ok, understood. :)

But maybe it would also be better to append a randomly generated text (6-10 characters, or more) after the number to make sure no files are overwritten if someone else used “Ham Sandwich” in the new field?

Especially in the case of the same user’s subsequent submission(s) using the same Prize Name. For example, a submission of files followed by another of links. Come to think of it, there is probably a high probability of this.

@Hilleary: download a test-version from http://dropbox.kingofcomedy.de/. :)

@Thorsten: It looks good. Can I make the file-prefix field be mandatory? It doesn’t seem to be.

@Hilleary: afaik it is not possible to check the dropbox-folder before uploading. Check my new test-version which I have uploaded some seconds ago.

http://dropbox.kingofcomedy.de

First I thought about using the timestamp too, but: it might be a problem if two students are using the same file-prefix at the same time. Not very likely but possible. I have used a md5-hash instead.

So am I the only one that noted that the script only check the password integrity AFTER the whole file has been uploaded? If someone mistype the pwd and submit a large file, he/she will only know after the upload is completed. He/she will have to upload again. Any way to check the password before the submission of the form?

I’ll make a final version later this week, but I don’t have the time (at least at the moment) for a proper documentation, sorry.

I found this now and it is amazing. On my site I use your 1.1.5 version of script. I translate it for me and use it for send file to specific folder named PrintQueue. All files (doc, xls, pdf, jpg etc..) are automaticaly printed by default printer on my home computer. I use eprint.vbs and it works perfect. I just upload file from my blackberry or some computer and in my home i have printed file.
Your nev versions with renamed options and multiple file upload or link option is for me not necessary.
Many thanks for your grat work.

This doesn’t work (with or without password). The file is never uploaded to Dropbox.

I’ll try to find a solution in my next (kingofcomedy)-version in the next days. Instead of writing to /tmp/ it should work if the script is writing directly to the script-folder.

Hello. I just tried the version 0.8.

Set the script folder to 777 (the folder in which the script resides).

The file seems to upload (or at least it waits while it appears to upload), then the error message is displayed:

Cannot rename uploaded file.

I poke and prod and tweak with no luck.
PHP version is 5.1.6

@HJE: are you using my version 0.8? Is the folder set to 777 (the webserver-user need the rights to create folder/files)?

@Frank: weird. I’ll see what I can do.

Keep getting this error message :

*****************
Warning: mkdir() [function.mkdir]: Permission denied in D:\Hosting\5161110\html\gen_upload1\index.php on line 120

Error: Cannot create temporary directory!
*****************

I am using the following:

- GoDaddy Hosting account with PHP 5 enabled

- Version 0.8 of the script

- User has 777 rights.

Hi,

I’ve been looking for a script like this and was very glad to come across this one. However, I am getting this error:

Parse error: syntax error, unexpected T_IF in /home/content/b/o/t/botportart/html/botticelliportraits/upload/du/index.php on line 27

Any ideas?

@Christie: it is no problem to include a mail-function, if your webhoster supports this function. I’ll include this feature in the next test-version.

I have just uploaded a new test-version with email-functionality. Please download and test it:

http://dropbox.kingofcomedy.de/

Thanks.

Great project Thorsten. Got a quick question. I have the script running on one of my pags, and if I have 3 file upload fields on the page, only the first 2 of the 3 upload… if I have 4, then the first 3 upload etc… always seems to not upload that last one in the list.

Any clues?

@Thorsten: I’m really loving your script, suits my needs perfectly! Just one issue though, I can’t seem to get email notifications working correctly and keep getting this error:

SMTP Error: Could not connect to SMTP host. Mailer Error: SMTP Error: Could not connect to SMTP host.

I have only edited the index.php to provide mail server/login info, should I be modifying the phpmailer and smtp .php files too? Could you please let me know which files I should be editing?

Thanks again!

@Lunas: ask your hoster to install the cURL-Extension for PHP.
