I had to send emails to all the Blog admins in our WordPress Multisite installation. This is how I did it:
[code lang=”php”]
<?php
# Alert Blog Admin php script
# connect to blog db, select from, find all blog admin email adresses
# get subject, body from pre-created local files, send the email
# how to run the script
# php alertblogadmin.php -s subjecttext.txt -b bodytext.txt
$mysqlserver="localhost";
$mysqluser="dbuser";
$mysqlpassword="XXXXXXX";
$database="blog";
$ERROR=0;
# This script require arguments
$arguments = getopt("s:b:f:dr");
# Test if array $arguments as at least s,b and r
# maybe to make sure that $arguments array contains at least 3 items?
if ( count($arguments) < 3 ){
echo "Missing arguments…\n";
echo "Usage: php alertblogadmin.php -s subjecttext.txt -b bodytext.txt\n";
die;
}
# 2 text files need to exist
if ( !file_exists($arguments["s"])) {
echo "File $arguments[s] does not exist?\n";
$ERROR=1;
}
if ( !file_exists($arguments["b"])) {
echo "File $arguments[b] does not exist?\n";
$ERROR=1;
}
if ($ERROR == "1"){
die;
}
$link = mysql_connect($mysqlserver, $mysqluser, $mysqlpassword);
if (!$link) {
die(‘Could not connect: ‘ . mysql_error());
}
mysql_select_db ($database,$link);
# collect blogs
$sql="SELECT blog_id from wp_blogs where deleted not like ‘1’";
$result=mysql_query($sql,$link);
if (!$result) {
die(‘Invalid query: ‘ . mysql_error());
}
$i = "0";
$emailarray = array();
while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
$blog_id = $row[0];
$table = "wp_" . $blog_id . "_options";
# Find email adresses to admins in each blog in the system
$sql2="SELECT option_value FROM $table WHERE option_name = ‘admin_email’";
$result2=mysql_query($sql2,$link);
while ($row2 = mysql_fetch_array($result2, MYSQL_NUM)) {
$emailarray[$i] = $row2[0];
}
$i++;
}
# sort the email array and find unique emails
asort($emailarray);
$emailarray = array_unique($emailarray);
$emails = "";
foreach ($emailarray as $email) {
$emails .= $email.",";
}
$emails = substr($emails,0,-1);
# Could be smart to see who you will be sending your email to
echo $emails;
# open subject and body text files
$subject = file_get_contents($arguments["s"]);
$body = file_get_contents($arguments["b"]);
$from = $arguments["r"];
# Use this one to test before you actuelly send to $emails, which is a variabel that might contain hundreds of emails.
# You really would like to test first
$bcc = "user1@something.com,user2@something.net";
//$bcc = $emails; # uncomment this one, when you are ready to go
$headers = "From: noreply@something.com" . "\r\n" .
"Reply-To: noreply@something.com" . "\r\n" .
"Bcc: $bcc" . "\r\n" .
"X-Mailer: PHP/" . phpversion();
$header_ = ‘MIME-Version: 1.0’ . "\r\n" . ‘Content-type: text/plain; charset=UTF-8’ . "\r\n";
mail(”, ‘=?UTF-8?B?’.base64_encode($subject).’?=’, $body, $header_ . $headers);
mysql_close($link);
?>
[/code]
