Typo3 Mask – Javascript and CSS includes of extensions missing

Filed under: JavaScript,Typo3 — Tags: , , , , , , — Christopher Kramer @ 11:36

I was using Mask 2.1.1 with Typo3 7.6.11 for a site as described in the Mask manual with this typoscript:

page < temp.mask.page
page.10.file.stdWrap.cObject.default.value = fileadmin/templates/index.html
page {
        includeCSS.styles = fileadmin/templates/style.css
}

The problem with this was that the CSS and JS files includes from extensions where missing, even though the static templates of this where included. The reason is that this typoscript overwrites the page.include* stuff defined by the templates. To solve this, I copied the page.include* stuff defined by the extensions in a temporary variable and restored it after loading the mask object into page:

tempJSFooterlibs < page.includeJSFooterlibs
tempJSFooter < page.includeJSFooter
tempCSS < page.includeCSS

page < temp.mask.page
page.10.file.stdWrap.cObject.default.value = fileadmin/templates/index.html
page {
        includeJSFooterlibs < tempJSFooterlibs
        includeJSFooter < tempJSFooter
        includeCSS < tempCSS

        includeCSS.styles = fileadmin/templates/style.css
}

There are more includes you might need to consider if your extensions use these:

page.includeJS
page.includeJSlibs
page.jsInline
page.jsFooterInline

Hope this helps someone with the same problem! Please let me know if there is an easier solution.

Roundcube: Multiple identities (mail_domains) automatically created by default when user is created

The problem

Roundcube is a popular webmailer written in PHP. Today I configured it on a host where each user has multiple identities, one for each domain: E.g., user bob has the three identities:
bob@example1.org, bob@example2.org and bob@example3.org

The same for all other users.

When the user logs in for the first time in roundcube, all three identities should be automatically created. There is a config variable mail_domain, which can be used like this:

$config['mail_domain'] = 'example1.org';

This will make sure that when user bob logs in, the created identity will be bob@example1.org . You can give an array here, but only one domain per IMAP host. So using mail_domain, it seems that you currently cannot define multiple domains that will create different identities.

The solution

The solution that I found uses the plugin virtuser_query. This plugin lets you query mail identities from an SQL database. But within the SQL query, you can also statically configure all the domains like this:

$config['virtuser_query'] = array('email' => 
'SELECT "%u@example1.org" UNION 
SELECT "%u@example2.org" UNION 
SELECT "%u@example3.org"',
'user' => '', 'host' => '', 'alias' => '');

The plugin replaces %u with the username, e.g. bob. So this query will always return three rows, one for each domain. It is not really querying the database, it is just a workaround to configure multiple default domains in roundcube, as mail_domain currently does not allow us to do this.

For the plugin to work, you need to enable it like this:

$config['plugins'] = array(...,'virtuser_query'); 
// note: there is an underscore after virtuser

In my case the virtuser_query plugin was already included in Roundcube as I have installed the Debian package roundcube-plugins . If it is not already part of your roundcube installation, you can get in here.

I hope this helps somebody to solve this issue faster 🙂
Please leave a comment if it helped you, if you have problems with this, or if you found another way.

Typo3: Redirect backend to https and frontend to http

Filed under: PHP,Security,Server Administration,Typo3 — Tags: , , , , , , , , , — Christopher Kramer @ 20:02

If you are using SNI to secure the access to your site through SSL, you might decide that you do not want to use SSL for the frontend, as users of old clients such as Android 2 or Internet Explorer 8 on Windows XP won’t be able to access the site. But for the backend, old clients should not be a problem.

So this solves the redirection in two ways:

  1. Frontend gets redirected to HTTP if accessed through https (optional)
  2. Backend gets redirected to HTTPS if accessed through http

Put this in your .htaccess after “RewriteEngine On” (assuming Apache webserver):

# 1. optionally: redirect FE to http
RewriteCond %{HTTPS} on
RewriteCond %{REQUEST_URI} !^/?typo3
RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

# 2. redirect BE to https
RewriteCond %{HTTPS} off
RewriteCond %{REQUEST_URI} ^/?typo3
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

And hopefully, your backend access is now securely encrypted…

phpLiteAdmin is now hosted on bitbucket

Filed under: phpLiteAdmin — Christopher Kramer @ 19:43

As Google code is shutting down, the open source project phpLiteAdmin which was hosted on google code all the time needed a new home. The team decided to use bitbucket. There were several reasons why we did not go for the most obvious one – github. Mainly, github does not offer some features we need.

I moved all the issues from the issue tracker to bitbucket and also imported the wiki pages and converted them into markdown syntax so everything is nice again. Downloads are also hosted on bitbucket now.

The git source repository is available on bitbucket as well as github. So if you want to fork phpLiteAdmin and send us pull requests, you can do so on any of the two plattforms.

This is phpLiteAdmin’s new home: https://bitbucket.org/phpliteadmin/public

And don’t tell us, you don’t want to create a bitbucket account – you don’t need to! You can log into bitbucket with your existing google, facebook, twitter or even github account!

The discussion group is still a google group.

wp-cli: syntax error, unexpected ‘?’, error connecting to the database

Filed under: Server Administration,Windows,Wordpress — Christopher Kramer @ 10:55

Running wp-cli on a website that was set up by somebody else resulted in a strange error:

PHP Parse error:  syntax error, unexpected '?' in phar:///usr/local/wp-cli.phar/php/wp-cli.php(23) : eval()'d code on line 1
Error:
<h1>Fehler beim Aufbau der Datenbank-Verbindung</h1>
...

The database settings in wp-config.php were all correct and WordPress was also working, so this did not seem to be the problem. In the end, I found out the reason was a byte order mark at the beginning of wp-config.php that had been inserted probably by Windows Editor. To solve the issue, the easiest way is to open the file in a good editor, for Windows I recommend PSPad, copy everything into the clipboard (CTRL +A, CTRL + C), create a new empty file (CTRL + N), paste everything (CTRL + V), save it (CTRL + S) as wp-config.php and upload the file.

Typo3 6.2 and Crawler Failed opening required ‘PATH_t3libclass.t3lib_page.php’

Filed under: Typo3 — Tags: , , , , , , — Christopher Kramer @ 11:28

Typo3 6.2 with the current version of the crawler from TER (3.5) gives this error when executed by the planner from cron:

PHP Fatal error:  require_once(): Failed opening required 'PATH_t3libclass.t3lib_page.php' (include_path='[...]') in [...]typo3conf/ext/crawler/class.tx_crawler_lib.php on line 30

Or if you open the crawler module in the Info-Module, you get only a blank screen and these errors in the log:

PHP Fatal error:  require_once(): Failed opening required 'PATH_t3libclass.t3lib_pagetree.php' (include_path='[...]') in [...]typo3conf/ext/crawler/modfunc1/class.tx_crawler_modfunc1.php on line 30, referer: http://[...]/typo3/mod.php?M=web_info&moduleToken=[...]

PHP Fatal error:  require_once(): Failed opening required 'PATH_t3libclass.t3lib_pagetree.php' (include_path='[...]') in [...]/typo3conf/ext/crawler/modfunc1/class.tx_crawler_modfunc1.php on line 30, referer: http://[...]/typo3/backend.php

I found a bug report for this exists in the crawler bugtracker for over a year now. And the current crawler version 3.6.2 also fixes the problem, but for some reason is not in the TER yet. So to solve the problem:

Download crawler version 3.6.2 and replace “/typo3conf/ext/crawler/” with the contents of this archive.

Hope this helps somebody solving the issue faster.

Owncloud: Upgrading to owncloud 8 fails (Integrity constraint violation in oc_filecache)

Filed under: Linux,PHP,Server Administration — Tags: , — Christopher Kramer @ 21:33

First, the upgrade to owncloud 8 in the web GUI failed. Then, I performed the upgrade in the console like this:

sudo -u www-data php /var/www/owncloud/occ upgrade

This gave an error like this (I don’t remember exactly):

An exception occurred while executing 'INSERT INTO "oc_filecache" ... Integrity constraint violation: key s_storage_path_hash is not unique
...
Upgrade failed

This owncloud is using a MySQL DB.

So what in the end solved the problem: First put Owncloud in maintainance mode:

sudo -u www-data php /var/www/owncloud/occ maintenance:mode --on

Then make sure no occ processes of old upgrade attempts are running. If there are, kill them. Then clear the oc_filecache using this MySQL command:

TRUNCATE oc_filecache;

Don’t worry, it will populate itself again during the upgrade. Then restart the upgrade:

sudo -u www-data php /var/www/owncloud/occ upgrade

This might take a lot of time! Better run this on a screen (see screen tutorial if you don’t know how) so it does not stop when your SSH connection breaks.

Updating to PHP 5.4 causes missing Text

Filed under: PHP,Server Administration — Tags: , , , , , , — Christopher Kramer @ 14:29

After updating from PHP5.3 to PHP 5.4, on some sites text was missing. No error could be found in the error log so I had to dig into the code to find out what was going on.

The root cause is that with PHP5.4, the default character set expected by htmlentites(), htmlspecialcharacters() and html_entity_decode() changed from ISO-8859-1 to UTF-8. So if a script passes ISO-8859-1 characters like German “Umlaute” (öäüÖÄÜß) to one of these functions without specifying the charset with the corresponding parameter, these functions will return an empty string. And unfortunately, with PHP 5.4, they also removed the error message that PHP 5.3 recorded in the logfile in this case. This makes finding the problem a lot more difficult.

So what can you do about it? You could

  1. Use PHP 5.3 😉
    Here is a blog post on downgrading to PHP 5.3. on Debian Wheezy
  2. change the used charset to UTF-8
    This might require changing the character set in files, databases or config files, depending on what is used on the site.
    I explained in a blog post how to change the charset in Typo3 to UTF-8 back in 2012.
  3. Provide ISO-8859-1 as a parameter to all calls of htmlspecialcharacters() etc.

So for the third option, what you have to do is find places like this:

htmlspecialchars($string);

And replace them with something like:

htmlspecialchars($string, ENT_COMPAT | ENT_XHML, 'ISO-8859-1');

The problem is that it’s hard to do this automatically. What is easy to do, is replace all htmlspecialchars()-calls with calls to htmlspecialchars_PHP5-3() etc. and place these functions there:

function htmlspecialchars_PHP5-3($string, $ent=ENT_COMPAT, $charset='ISO-8859-1') {
    return htmlspecialchars($string, $ent, $charset);
}

function htmlentities_PHP-5-3($string, $ent=ENT_COMPAT, $charset='ISO-8859-1') {
    return htmlentities($string, $ent, $charset);
}

function html_entity_decode_PHP-5-3($string, $ent=ENT_COMPAT, $charset='ISO-8859-1') {
    return html_entity_decode($string, $ent, $charset);
}

So just do a search & replace over all files and make sure that all scripts have a file included that contains these functions.

Typo3 ts_lastupdate: Change Text

Filed under: Typo3 — Tags: , , , — Christopher Kramer @ 12:38

The Typo3 extension ts_lastupdate comes in handy when you want to automatically display the date when the page has been edited the last time. On a German Typo3 installation, what it displays looks like this:

Letzte Änderung: 09.10.2013

You can configure the date format as described in the documentation. But what I missed was a way to configure the text before the date. I wanted it to say “Letzte Aktualisierung” instead of “Letzte Änderung”. The solution I came up with might be a bit quick and dirty but it surely does the trick:

plugin.tx_tslastupdate_pi1.text.wrap =  <!--|-->Letzte Aktualisierung:

So what I do is wrap the text provided by the extension (or rather language file) in comments and place my text afterwards. If you have multiple languages, you might need to use language conditions.

[globalVar = GP:L = 2]
plugin.tx_tslastupdate_pi1.text.wrap =  <!--|-->Letzte Aktualisierung: 
[globalVar = GP:L = 3]
plugin.tx_tslastupdate_pi1.text.wrap =  <!--|-->Last update: 
[global]

If anybody finds a cleaner solution, please let me know.
