Lua

Send HTML Email with Image to iPhone

Demonstrates how to compose an HTML email with an embedded image that will display correctly on an iPhone. This example produces an email that looks like this on the iPhone:

Lua

local chilkat = require("chilkat")

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

-- The mailman object is used for sending and receiving email.
local mailman = chilkat.MailMan.new()

-- Use your SMTP server hostname.  This example uses office365, but it could be any SMTP server..
mailman.smtp_host = "outlook.office365.com"
mailman.smtp_port = 587
mailman.start_tls = true

-- Set the SMTP login/password
mailman.smtp_username = "OFFICE365-SMTP-LOGIN"
mailman.smtp_password = "OFFICE365-SMTP-PASSWORD"

-- Create a new email object
local email = chilkat.Email.new()
email.subject = "Testing for Chilkat SMTP API..."
email.body = "Testing for Chilkat SMTP API..."
email.from = "Chilkat Support <my-office365-user@mydomain.com>"
email:add_to("Chilkat Support", "support@chilkatsoft.com")

-- For whatever reason, the iPhone's email program requires
-- images in HTML to be referenced by Content-ID.  Therefore,
-- we must add the image like this:
local contentIdStarfish = email:add_related_file("qa_data/jpg/starfish.jpg")
if not email.last_method_success then
    print(email.last_error_text)
    return
end

-- The src attribute for the image tag is set to the contentIdStarfish:
local sbHtml = chilkat.StringBuilder.new()
sbHtml:append("<html><body><p>This is an HTML email with an embedded image.</p>")
sbHtml:append("<p><img src=\"cid:CONTENT_ID_STARFISH\" /></p></body></html>")
local numReplacements = sbHtml:replace("CONTENT_ID_STARFISH", contentIdStarfish)

email:set_html_body(sbHtml:get_as_string())

local success = mailman:send_email(email)
if not success then
    print(mailman.last_error_text)
else
    print("Mail Sent!")
end
