May 08, 2008  Best Answer: Octet-stream is just a generic name for a file that has no explicit file type (all files are really octet streams). You'd have to know what application is supposed to or can open it and set things up so that application is called. Jun 1, 2012 - Hi. On the method of the action, there is a parameter wdevent. It will contain the information. Elem = wdevent->get_context_element( ). I have simply implemented some checks on the file extension and if the content-type shows as application-octet stream I have then assigned it depending on what the file extension is. This is a nasty hack for the reasons I have stated in my previous post so if anyone has a simple solution that would work better I would love to know!

A multipurpose internet mail extension, or MIME type, is an internet standard that describes the contents of internet files based on their natures and formats. This cataloging helps the browser open the file with the appropriate extension or plugin. Although the term includes the word “mail,” it is used for web pages, too.

MIME types contain two parts: a type and a sub-type.

  1. The type describes the categorization of MIME types that are linked to each other.
  2. In contrast, a subtype is unique to a specific file type that is part of the type.

Here is the MIME type for HTML:

MIME types are defined in HTML by the

attribute on links, objects, and script and style tags.

Distinguishing Among MIME Types

Following is a list of most MIME types, with their file extensions and the applications that use them. Many computers use file extensions to help identify file types. So, if you have a file with an odd extension on your website, you can look up the MIME type in this list.

Some types are prefixed with X, and some are prefixed with VND. These prefixes, respectively, refer to sub-types not listed with the Internet Assigned Numbers Authority or values specific to a vendor.

In this section, we will introduce to you how to handle form-based file uploads with a PHP script. The techniques are the same for HTML and XHTML. At the time of writing, the latest version of PHP is 5.2.0. So, we assume you are using PHP 5.2.0 in this tutorial. For other versions of PHP, the procedures should be similar. If you are not familiar with PHP, you may want to read some introductory tutorials before going through this section.


Parsing Form Data and Getting Information about the Uploaded File with PHP

Application Octet Stream File Extension

To extract an uploaded file from an HTTP request, we need to parse the form data that is encoded in the 'multipart/form-data' format. In PHP, the form data in an HTTP request is automatically parsed. The PHP engine stores the information of the uploaded files in the $_FILES array.

Now let's say the name attribute value of the <input type='file'> element in a certain HTML/XHTML/XHTML MP document is myFile. To obtain the information about the uploaded file, use the following lines of PHP script:


/* Get the size of the uploaded file in bytes. */
$fileSize = $_FILES['myFile']['size'];
/* Get the name (including path information) of the temporary file created by PHP that contains the same contents as the uploaded file. */
$tmpFile = $_FILES['myFile']['tmp_name'];
/* Get the name of the uploaded file at the client-side. Some browsers include the whole path here (e.g. e:filesmyFile.txt), so you may need to extract the file name from the path. This information is provided by the client browser, which means you should be cautious since it may be a wrong value provided by a malicious user. */
$fileName = $_FILES['myFile']['name'];
/* Get the content type (MIME type) of the uploaded file. This information is provided by the client browser, which means you should be cautious since it may be a wrong value provided by a malicious user. */
$contentType = $_FILES['myFile']['type'];
