PHP Script

This PHP script is used both for uploading and downloading files. When the script is installed and you the type the full address of the upload webpage, you will get something like this:

php.ini: upload_max_filesize = 200M
php.ini: post_max_size = 100M
No file uploaded

With this utility you can upload or download your files to and from your android device and another computer with a web server. Note that the directory (folder) where the files is stored is called "upload". Only certain file types can be uploaded. ( gif ,jpeg ,jpg ,png ,pdf ,doc ,txt ,csv ,gpx ,xml ,db)

END OF FILES 

I am outputting the php.ini setup values upload_max_filesize and post_max_size for your convenience because these values give a lot of problems when trying to upload big files. (The upload fails and you have no idea why.) After this, some more information of what is allowed to be uploaded is shown. From this android application, we just upload CSV, DB, GPX and XML files, but I allowed some other files to be uploaded as well. After this there is a table of all the files that were uploaded before. Here you can click on any file to download it to your computer. The file upload time and size is also displayed. This information is repeated once again but in a different format. This different format is made for the android application to find the files that is available for download. The words just before and just after are used by the android application to find this file information. Anyone modifying this php script should take this into account. (This script can be used to implement your own cloud storage. It is free for use.)

The PHP script is as follows:

The procedure for installing this on a linux server will be as follows: (In the examples below we assume that the web servers root directory is /var/www/html. We will put our script in a directory called android and that the uploads folder will be called upload in the android directory.)

• Go to the document root of the web server
  # cd /var/www/html
  
• Create the android directory
  # mkdir android
• Create the upload directory
  # mkdir android/upload
• Fix the permissions of these directories
  # chown -R apache:apache android
  
• Download the index.php script directly to the /var/www/html/andoid/index.php. Make sure you save the file as index.php, not index.php_. If you cannot save the file directly there then save it somewhere else and copy the downloaded file into the android directory
  # cp whereever_the_index_file_above_was_downloaded_to /var/www/html/android/index.php
  If you copied the contents of the frame, then do the following:
  # cat - > android/index.php
  Then press Crtl-D (that is keep the control key down and press d) to save the file
  
• Password control should be implemented if this web server is visible on the internet. A .htaccess file or Directory directive should be used to set up password control. A .htaccess could look like this:
  

  You can download the .htaccess file directly to /var/www/html/android/.htaccess. Make sure you save the file as .htaccess and not just htaccess. If you cannot save the file directly there then save it somewhere else and then copy it there like above, or you can copy the above text with your mouse and then:
  # cat - > android/.htaccess
  Then press Crtl-D (that is keep the control key down and press d) to save the file

• The password file can be created with the following command:
  # htpasswd -bc /etc/httpd/password_file username password
  This is the username and password you enter into the setup screen.

The URL you should use in the setup screen will then be something like
http://some_sample_domain.com/android/index.php
