Alright! I finished...I think. ;) I generalized the code and removed almost all of the hardcoding. I left things like generated HTML in since it is easy to change.
Ok, the code involves 6 files, two of which can be created from scratch since they begin blank. All of these files need to be in your blog directory.
*THIS HACK HAS ONLY BEEN TESTED WITH VERSION 0.8.2.2 IF YOU WANT ONE FOR 0.8.6 WAIT FOR THE OFFICIAL RELEASE!*
First file is 'sendmail.php'
This file parses the information sent by the submission and generates a conformation page based on success/failure of the email address.
Save the following code as sendmail.php
Code:
<?
require_once("b2config.php");
import_request_variables("P", "I_");
$to = $admin_email;
$from = $I_contents;
$from_header = "From: $from";
$subject = "Mailing List Addition";
if($form = !"")
{
// is the $from email address in valid format?
if(ereg("([[:alnum:]\.\-]+)(\@[[:alnum:]\.\-]+\.+)", $from))
{
if(file_exists("email_list.txt"))
{
$newfile = fopen("email_list.txt", "r");
flock($newfile, 2);
while(!feof($newfile))
{
$duplicate = fgetss($newfile, 255);
// is email address submitted already on file?
if(eregi("$from", $duplicate))
{
print("<HTML><Head><Title>Mailing List Error</Title></Head><BODY background=\"YOUR_BG.jpg\" text=\"white\">");
print("<P ALIGN=\"CENTER\"><FONT SIZE=\"4\">This email <strong>$from</strong>");
print(" is already in the database. <br>Please go back");
print("</FONT></BODY></HTML>");
flock($newfile, 3);
fclose($newfile);
exit;
}
}
flock($newfile, 3);
fclose($newfile);
$addemail = fopen("email_list.txt", "a");
flock($addemail, 2);
fputs($addemail, "$from\n");
flock($addemail, 3);
fclose($addemail);
//send mail - $subject & $contents come from surfer input
mail($to, $subject, $from, $from_header);
// redirect to correct Message--Edit HTML if you wish
print("<HTML><Head><Title>Subscribe Complete!</Title></Head><BODY background=\"YOUR_BG.jpg\" text=\"white\">");
print("<P ALIGN=\"CENTER\"><FONT SIZE=\"4\">");
print("Thank you for signing up for the mailing list.<br>Every time a new post is added, you will recieve an update via email.");
print("</FONT></BODY></HTML>");
}
}
else
{
print("<HTML><Head><Title>Mailing List Error</Title></Head><BODY background=\"YOUR_BG.jpg\" text=\"white\">");
print("<P ALIGN=\"CENTER\"><FONT SIZE=\"4\">This email address: <strong>$from</strong>");
print(" is not valid. <br>Please go back");
print("</FONT></BODY></HTML>");
}
}
else
{
print("<HTML><Head><Title>Mailing List Error</Title></Head><BODY background=\"YOUR_BG.jpg\" text=\"white\">");
print("<P ALIGN=\"CENTER\"><FONT SIZE=\"4\">Please enter an email address.</FONT></BODY></HTML>");
}
?>
Don't forget to edit the HTML to your liking.
Now, add the following HTML to your post page or where you want you're submission box.
Code:
<FORM ACTION="sendmail.php" METHOD="POST" ENCTYPE="application/x-www-form-urlencoded">
<INPUT TYPE="TEXT" NAME="contents" SIZE="18"><br />
<INPUT TYPE="SUBMIT" NAME="Sign-up" VALUE="Submit"><br />
</form>
The names must not be changed, but the layout, etc...
Next file is the unsubscribe.php--this handles the automatic unsubscribe from the mailing list.
Save the following as 'unsubscribe.php'
Code:
<?
require_once("b2config.php");
import_request_variables("G","I_");
$id = $I_id;
if($id != "")
{
$emails = file("email_list.txt");
for($index = 0; $index < count($emails); $index++)
{
if(ereg("$id", $emails[$index]))
{
$emails[$index] = "";
$thefile = fopen("email_list.txt", "w");
flock($thefile, 2);
for($newindex = 0; $newindex <count($emails); $newindex++)
{
if($emails[$newindex] != "")
{
fputs($thefile, "$emails[$newindex]");
}
}
flock($thefile, 3);
fclose($thefile);
//Edit html to liking
print("<HTML><Head><Title>Unsubscribe</Title><BODY background=\"YOUR_BG.jpg\" text=\"white\">");
print("<P align=\"Center\"><font=\"4\">This email <strong>$id</strong>");
print(" has successfully been removed from the");
print(" database.</font></BODY></HTML>");
mail("$admin_email", "Mailing List Unsubscribe", "$id", "From: $id");
}
}
}
?>
This code only works if an email address is sent to it via get.
Now, create a blank file named 'email_list.txt'
This file will store the emails for the mailing list.
Next is the admin interface. I put it all into a single file for space and security. It controls adding, removing, and mailing from the mailing list.
Save the following code as 'mailinglist.php' Don't forget to change the 'b2menutop.txt' file to add this.
Code:
<?php
import_request_variables("P", "P_");
import_request_variables("G", "G_");
$action=$P_action;
$error="";
$mm="";
$rm="";
$title = "Mailing List";
/* <Mailing List> */
$standalone=0;
require_once("b2config.php");
require_once($b2inc."/b2template.functions.php");
require_once($b2inc."/b2verifauth.php");
require_once($b2inc."/b2vars.php");
require_once($b2inc."/b2functions.php");
require_once($b2inc."/xmlrpc.inc");
require_once($b2inc."/xmlrpcs.inc");
get_currentuserinfo();
//Set user Level
if ($user_level <= 8) {
die("You have no right to send mail for this blog.<br>Ask for a promotion to your <a href=\"mailto:$admin_email\">blog admin</a> :)");
}
//Self Containing the Code -- if hidden for each FORM function is returned, that switch statement executes
switch($action)
{
case "sendmail":
//The Following is SENDMAIL code until end in comments--Sends mass mail

if($P_subject !="")
{

The code sets the from info based on the logged in user--set admin privledges to change who can get at it.
Next is the auto-update for sending updates about posts. This file, when run, sends an email that lists:
number of new posts since last run
a url the most recent posts, by day
which catagories have been updated
a url to the updated catagories
If you want this to run from server side, you need to schedule it. If its a UNIX box, check with you administrator to see if you can use crontab. online.
Save the following as 'auto.php'
Code:
<?php /* Don't remove this line, it calls the b2 function files ! */ $blog=1; include ("blog.header.php");
//What you would like displayed as the nick in the 'from' line
$nick="YOUR NICK";
//Subject of the email
$subject="I've updated my posts!";
//Check to make sure it hasn't been run yet.
$auto_check=fopen("auto.txt", "r");
flock($auto_check, 2);
$check=fgetss($auto_check, 9);
flock($auto_check, 3);
fclose($auto_check);
//Correct for blank file
if($check=="")
{$check="yesterday";}
//If it hasn't been run, run the script and update the check file
if(strtotime($check)<strtotime(date("Ymd")))
{
$stamp=date("Ymd");
$auto_update=fopen("auto.txt", "w");
flock($auto_update, 2);
fputs($auto_update, "$stamp");
flock($auto_update, 3);
fclose($auto_update);
$my_date=mktime(0,0,0,date("m"),date("d")-1,date("Y"));
$my_date = date("Ymd",$my_date);
$its_date="";
//If it can run, get info for email--DON'T TOUCH THIS SECTION UNLESS YOU KNOW WHAT YOU ARE DOING!!
$count=0;
$o_count=0;
//Begin to loop to check for new posts
$my_array_cat=array();
$my_array_num=array();
while($row = mysql_fetch_object($result)) { start_b2();
$its_date=mysql2date('Ymd', $postdata['Date']);
if($its_date>=$my_date)
{
$in_count=0;
$is_found=0;
foreach($my_array_cat as $cat)
{
$in_count+=1;
if($postdata['Category']==$cat)
{
$is_found=1;
$my_array_num[$in_count]=($my_array_num[$in_count]+1);
}
}
if($is_found==0)
{
$my_array_cat[$in_count+1]=$postdata['Category'];
$my_array_num[$in_count+1]=1;
$count+=1;
}
$o_count+=1;
}
}
//Ian's code--Send the email
if($count!=0)
{
if($count > 1){$suffix = "s";}
else {$suffix = "";}
$from="From: $nick $admin_email";
$file=fopen("email_list.txt", "r");
flock($file, 2);
while(!feof($file))

else
{
print("<HTML><HEAD><TITLE>ERROR</TITLE><BODY><CENTER>THIS SCRIPT HAS ALREADY BEEN RUN. YOU CANNOT RUN IT AGAIN TODAY.");
print("</CENTER></BODY></HTML>");
}
//End of Ian's code
?>
After this, all you need to do is create a blank file named 'auto.txt' This file is for checking when the script was last run to prevent it from being run more than once a day.
Changing the script to update on a post-by-post basis is slightly different.
Open 'b2edit.php' and locate the 'case: "update" '
Add the code from 'auto.php' after the user_level check and it will run everytime you hit 'blog this!'
I think that's all there is to it. If I left something out, or something doesn't work, let me know. I've tested it, and all I find is a typo from time to time.
Best of luck,

This is a great code, but do you have one of these for b2evo version 0.9.0.11?
