Upgrade Moodle 2.2.1 to 2.6.2+

I tried to upgrade Moodle 2.2.1 to 2.6.2+ and got this error message:

The solution was to run these sql’s at the Mysql database:

This issue seems to be related to:

Mysql SQL in bash one-liner

If you just need a quick way to get some data from a mysql database in your shell (bash), you could do something like this in one line:

If you don’t like to scroll:
-bash-3.2$ mysql -h your.server.edu -u db_username -pcat /path/to/your/homedir/secretpasswordfile -e "use databasename; SELECT tablename.columnname FROM tablename where id like '421111' and something like '1' and option like '23';" > /tmp/datayouwant.txt; while read i; do echo "$i"; done < /tmp/datayourwant.txt | sort | uniq

On my server I would then get a list of words/numbers or whatever you might have in the database, which one might want to use further in another script or command:

Open Journal Systems
Postgresql og Mysql
Redhat Enterprise Linux 6 (RHEL6)
Webmail (RoundCubemail)

Finding spam users

We had a lot of spam users in our multisite wordpress system. This was because we had self-registration enabled for a period. Not a smart thing to do…

anyway, I wrote a bash script in order to find which users id’s from the Mysql database that could potentially be spam users. With this list of ID’s I would run another SQL directly where I would set the “spam” to the number “1”. This would make sure the user could not log in, and after a month or so, the user could be deleted.

As you can see from one of the sql’s, the “%uib.no” is the trusted emails from our organization.


Alert Blog Admin php script

I had to send emails to all the Blog admins in our WordPress Multisite installation. This is how I did it:

# 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



# 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";

# 2 text files need to exist
if ( !file_exists($arguments["s"])) {
  echo "File $arguments[s] does not exist?\n";
if ( !file_exists($arguments["b"])) {
  echo "File $arguments[b] does not exist?\n";

if ($ERROR == "1"){

$link = mysql_connect($mysqlserver, $mysqluser, $mysqlpassword);
if (!$link) {
  die('Could not connect: ' . mysql_error());
mysql_select_db ($database,$link);

# collect blogs
$sql="SELECT blog_id from wp_blogs where deleted not like '1'";
if (!$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 $table WHERE option_name = 'admin_email'";
  while ($row2 = mysql_fetch_array($result2, MYSQL_NUM)) {
    $emailarray[$i] = $row2[0];

# sort the email array and find unique emails
$emailarray = array_unique($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);
