Add a String Attachment to an Email

See more Email Object Examples

Demonstrates the Chilkat Email object's AddStringAttachment method, which adds an attachment directly from an in-memory string — no file needs to exist on disk. The 1st argument is the filename that is written into the MIME (it is not a path to a file that is read), and the 2nd argument is the text that becomes the attachment's body. In this example we build a simple email, attach a small CSV file named people.csv straight from a string, and then print the resulting MIME so you can see the attachment embedded in the message.

-- This example demonstrates the Email object's AddStringAttachment method.
-- AddStringAttachment adds an attachment directly from an in-memory string.
-- The 1st argument is the filename to be placed in the MIME (not a file to be read).
-- The 2nd argument is the text content that becomes the attachment body.

local email = chilkat.Email.new()

email.subject = "Email with a string attachment"
email.body = "See the attached CSV file."
email.from = "mary@example.com"
email:add_to("Joe", "joe@example.com")

-- The text content of the attachment.
local csvData = "id,name\r\n1,Alice\r\n2,Bob\r\n"

-- Add the string as an attachment named "people.csv".
email:add_string_attachment("people.csv", csvData)

-- Show the full MIME of the email, which now includes the attachment.
print(email:get_mime())
