database in: http://pzwart3.wdka.hro.nl/~acastro/cgi-bin/traces-database.xml

Part1 Form and email subscription into database

• online form: where users subscribe their email address

• cgi receives email address appends it within the today's date node in traces-database.xml

http://pzwart3.wdka.hro.nl/~acastro/cgi-bin/traces_form_handler.cgi:

#!/usr/bin/python2.6
import cgi, cgitb, lxml.etree, datetime, os

today = datetime.datetime.now().strftime("%Y-%m-%d") #not sure is this is the best format

# Create instance of FieldStorage 
form = cgi.FieldStorage() 
# Get email from form 
email = form.getvalue('email') 


print "Content-Type: text/html"  
print                         
print "<TITLE>Form</TITLE>"
print "<H4>Your form was successfully added.<br />Shortly you will receive a message at %s </H4>" % (email)

#APPEND EMAIL AND DATE TO XML FILE

	addrs = lxml.etree.SubElement(dates, "address")#append grandchild
	addrs.text = str(email)
	tree = lxml.etree.ElementTree(root)
	tree.write('/home/acastro/public_html/cgi-bin/traces-database.xml', pretty_print=True, xml_declaration=True,encoding='utf-8')
	tree.close()

part2 and 3 Days calculations and sending emails

Script which parses xml database. Checks the dates and email address under each date.

According the date decide what part of story will be told

Examples on sending email

• multipart email - allows imgs attachments

import smtplib, email.utils
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart

#Reference: http://docs.python.org/library/email-examples.html


# address list
addr = ['andrecastro@c-e-m.org', 'andrecastro83@gmail.com']#, 'silviolorusso@gmail.com']

msg = MIMEMultipart()
#msg = MIMEText('This is the b@dy of the message.') #Create the message (simple ASCII)
msg['To'] = email.utils.formataddr(('Recipient', 'readers@traces.net'))
msg['From'] = email.utils.formataddr(('Traces', 'traces@noreply.net'))
msg['Subject'] = 'Traces Multipart - test'

msg.attach( MIMEText('This is the b@dy of the email') )

#attach a picture
fp = open('animpnky_e0.gif', 'rb')
img = MIMEImage(fp.read())
fp.close()
msg.attach(img)


server = smtplib.SMTP('localhost')
server.set_debuglevel(False) # show communication with the server
try:
    server.sendmail('traces@noreply.net', addr, msg.as_string())
finally:
    server.quit()

• text email - plain text

import smtplib, email.utils
from email.mime.text import MIMEText

# address list
addr = ['andrecastro@c-e-m.org', 'andrecastro83@gmail.com']
#, 'silviolorusso@gmail.com']

msg = MIMEText('This is the b@dy of the message.') #Create the message (simple ASCII)
msg['To'] = email.utils.formataddr(('Recipient', 'readers@traces.net'))
msg['From'] = email.utils.formataddr(('Traces', 'traces@noreply.net'))
msg['Subject'] = 'Traces plain - test '


server = smtplib.SMTP('localhost')
server.set_debuglevel(False) # show communication with the server
try:
    server.sendmail('traces@noreply.net', addr, msg.as_string())
finally:
    server.quit()
