Zend_Mime_Part

Introduction

This class represents a single part of a MIME message. It contains the actual content of the message part plus information about its encoding, content type and original filename. It provides a method for generating a string from the stored data. Zend_Mime_Part objects can be added to Zend_Mime_Message to assemble a complete multipart message.

Instantiation

Zend_Mime_Part is instantiated with a string that represents the content of the new part. The type is assumed to be OCTET-STREAM, encoding is 8Bit. After instantiating a Zend_Mime_Part, meta information can be set by accessing its attributes directly:

  1. public $type = Zend_Mime::TYPE_OCTETSTREAM;
  2. public $encoding = Zend_Mime::ENCODING_8BIT;
  3. public $id;
  4. public $disposition;
  5. public $filename;
  6. public $description;
  7. public $charset;
  8. public $boundary;
  9. public $location;
  10. public $language;

Methods for rendering the message part to a string

getContent() returns the encoded content of the MimePart as a string using the encoding specified in the attribute $encoding. Valid values are Zend_Mime::ENCODING_* Characterset conversions are not performed.

getHeaders() returns the Mime-Headers for the MimePart as generated from the information in the publicly accessible attributes. The attributes of the object need to be set correctly before this method is called.

  • $charset has to be set to the actual charset of the content if it is a text type (Text or HTML).

  • $id may be set to identify a content-id for inline images in a HTML mail.

  • $filename contains the name the file will get when downloading it.

  • $disposition defines if the file should be treated as an attachment or if it is used inside the (HTML-) mail (inline).

  • $description is only used for informational purposes.

  • $boundary defines string as boundary.

  • $location can be used as resource URI that has relation to the content.

  • $language defines languages in the content.
