If you need to reset the password of a Jenkins Continious Integration server. Stop Jenkins: usually /etc/init.d/jenkins stop edit the config.xml usually: /var/lib/jenkins/config.xml Replace true New false Possibly remove the Authorization configuration Restart the Server: usually /etc/init.d/jenkins start Now your Jenkins is absolutely insecure, you can just go to the web interface and edit users password. Do not forget to change back the security configuration, this could be done by a config.xml backup or through the web interface.

I just had to build in a Captcha to a simple form on a small side, i thought of using the Zend_Captcha_ReCaptcha but also saw some disadvantages. - Re Captcha is the most common used captcha, if anybody will build a universal spam bot, ReCaptcha might be first target to implement. - Re Captcha depends on a service so if you implement it your site will also depend on this service Implementing a Zend_Captcha_Image is pretty simple, it is not looking as nice as Re Captcha but also works. here is the code. The Zend_Captcha_Image has no standard view renderer, that is why we use the render function If there is time, i might implement a ultimate captcha solution, using Randomly choosen Zend_Captcha implementation this means a spambot would also have to implement different solutions.

As i did not post anything for one year cause of to less time for really good posts and always wanted to write better quality articles, i know decided to write some KISS articles. In these articles i will post some usefull small things wich might not always be high level enterprise but giving some good ideas.

It is possible to disable all form fields using Zend Framework Zend_Form class. maybe if the form is already send and you wanna display the data again inside form for optical reasons. This is not a serios possibility to avoid a form beeing send twice a CSRF token would be much more useful.

There were highly idiologic discussions about if you should test your privates or not with unit testing or not, in my opinion especially during Development with private methods performing for example calculations it could be useful to Unit Test these. At least during development you make sure that these functions already work, and finally it´s better to change accessibility than just to set accessibility lower to make testing possible. Before PHP 5.3.2 it was not possible to change the accessibility but with the new ReflectionMethod it is. But this feature needs to be used with care, it´s made for unit testing and maybe very special other cases wich are not in my mind yet. Using some magic reflection stuff always makes code very hard to read, maybe you think it´s fance but others might get confused a lot.

PHP Unit Developer Sebastian Bergmann wrote an article about Testing Your Privates
Sebastians Bergmanns Example:

To manipulate the result Zend_Controller_Request_Http::isXmlHttpRequest() maybe for testing XML Controllers in PHP Unit you just need to set the HTTP_X_REQUESTED_WITH value to XMLHttpRequest Zend_Controller_Request_Http::isXmlHttpRequest() does nothing more than checking for this. Zend_Controller_Request_Http::isXmlHttpRequest() from Zend Framework Code

This is a short tutorial how to remove duplicated entries from MySQL DB Table First idea was just to do a simple DELETE statement on a SubSelect Unfortunatelly this gives back an error message. #1093 - You can't specify target table 'ex_user' for update in FROM clause MySQL Documentation says about that

Error 1093 (ER_UPDATE_TABLE_USED) SQLSTATE = HY000 Message = "You can't specify target table 'x' for update in FROM clause" This error occurs in cases such as the following: UPDATE t1 SET column2 = (SELECT MAX(column1) FROM t1); You can use a subquery for assignment within an UPDATE statement because subqueries are legal in UPDATE and DELETE statements as well as in SELECT statements. However, you cannot use the same table (in this case, table t1) for both the subquery's FROM clause and the update target.

I was searching for a solution without using temporary table but didn´t find one yet. Well thats it.

I always liked some kind of auto generated model to access a database. I liked it the way Symfony does or the Zend Framework Tool. But anytime using a generator is also a bit of mess. The actual Zend Framework quickstart example has a 3 files way of implementing a Model, a Model Class, Model Mapper Class and Model DB Table ClassFew, so for one DB Table you always have to create 3 classes which look almost similar, most times you just copy and paste those, and change a few things. So i decided to create an very flexible model class, where you just need to define the properties and nothing more getter and sette methods will be called by magic functions. Even it has export function to an array. You don´t have to create anything but you can create your own functions for getter and setter methods which would override the default ones. In later state it could be possible to add a filter configurable in the model, but for first step i would like to keep it as slim as possible. The Danymic DBTable and DynamicMapper class are not tested yet, will post theme here later.

This example shows how to create an Zend Framework based SOAP Server and connect to it by a Java Client. The process itself is really easy but some things ara a bit tricky for example at the status were i created it there were some problems if using WS style for the SOAP Server so i decided to use RPC style. The Server basically allows a user to logon by credentials and gives back a userstatus, the Java Client is connecting through this service and requesting the userstatus. The Soap Server Class Zend Controller for the Soap Server Java Client Code With Netbeans a webservice client is really easy to create, right click on the project create new "Web Service Client" More Information: http://netbeans.org/kb/docs/websvc/jax-ws.html JAX RPC Style works better with Zend Framework and PHP. The Stub and Port classes will be Auto generated by Netbeans, so you don´t need to worry about that.

Using the OSAPI Open Social API, i noticed there is no session storage available by default, so this is a very quick way to implement a PHP-Session Bages Storage

I was working with which is a usefull function if you create forms using AJAX request. Simple usage is easy Executes the URL Item Add and replaces content of the Element with item_list with it´s result. Well what i would like to now is a Form which is permanent viewable and will reset itself if sended. What i guessed Well who that doesn´t work, form_remote_tag doesnt know an property called id, you have to hang it behind as html code This way it works, too bad the documentation on it is that poor. But 10 Reasons why Symfony **cks helped me out finding the right solution. However i still think updating a whole element with the list is the wrong way, i would like to use JSON and DOM Manipulation for that, to add exact one entry to the list, i gonna work that out now.

Searching the web i found a lot of solutions and ToolTip Plugins wie z.b. Simpletip oder really simple tooltop, but after i had a short look at some i decided that they are all more or less usefull. The most usuable entry i found was a short entry at Stackoverflow telling me anything i need to know. My basic requirement was, Javascript code has to be Seperated from the design and the Webpage content. So my php template looks like this So this was set cause whoever willing to change the content or layer of the tool-tip or preview div, however you like to call it, should be able to change it without touching the JS functionallity. So what i need to added now was CSS definition to hide tool-tip layer. So anybody could change layout later. Now everything is needed is not an extra plugin or collection of plugins it´s just a few lines of JS code using jquery I always wonder wy people code so many plugins for just so simple things, keep anything more complicated. Okay maybe it´s easier reusable but through most of them will not be maintained in one year or maybe are already lying arround for month, it is easier to just do it yourself. Even this solutions has some Advantages cause the Tooltip Div is already existing inside the site, Javascript doesnt need to pass through all links like for example here. And also a crawler would be able to read the content of the Tooltip Divs easiely. But however in some cases it makes sense to read the content of the Tooltip-Layers later for example if they requery more data, big pictures, calculations etc, it might be an option to read them later by Ajax Request.

It took me a little while to figure out to solve a standard problem like sending an template or view script as email, the main problem is the original documentation doesn´t show anything about it, just sending email with text from a string, and if you search on the web, you find mostly the same thing or solutions which were not satisfying me. The mail Template "mail.phtml" could contain text or HTML. Finally i choosed out this method as the best for sending email in Zend Framework Projects, maybe there would be one more better way, if i could put the subject inside the template file, i gonna save that for later.

User generated content in multilingual enviorments brings up new internationalizations problems, in a social network or other enviorment with a lot of User Generated content, I18N could not be sticked strictly to the user, and even a content or discussion could be spreaden through different languages. On usual websites a language is assigned to the frontend user, also on Youtube where it causes some problems. I always recieve Mails like

Komentarze do filmu „>videoname<” Comentario sobre ">videoname<" publicado Reactie van >userwhopostedcomment< op ,>videoname<' Nouveau commentaire sur ">videoname<" Kommentar zu ">videoname<" gepostet" gepostet

Which all mean your video ... has been commented by ..., but it´s alsways in the default language to the commentor, no matter what my language is and no matter which language the comment is Written in. Comments itself are mostly written in english or the language the video is in. A solution could be to send it just in the recipient´s default language instead the actual frontend language, it would just make it easier for the recipient.

Jeroen - Moie Video, echt Leuk Tommy - Why are all the Comments in Dutch Franz - Die Holländer finden ihre Sprache so Toll Antje - Ihre Sprache ist auch Supertoll Joost - Duits is alleen voor Moffen Tommy - In English Please Joost - German is for Kauts Only Franz - Geh doch Käse essen du Kaaskopp

As you see users could communicate through different Languages, and maybe they even like it and switch Languages during a conversation, if you wanna run your site with an international flavour this is acceptable. Language Detection Language Detection could be usefull, to translate auto detection for example, but you could also hide content with Language Detection For Example: I got a Guestbook entry on my Dutch Netlog, somebody commentet the guestbook in German with something like "Hi ich habe ein bischen Deutsch gelernt, Wie geht es dir? viele grüsse". This entry were hidden cause it weren´t written in my actual frontend Language (Dutch), but actually i had choosen German as native language in my profile. So if you use something like Language Detection to hide content from foreign Languages, you must consider a user could be able to understand more than one language. Hiding content from the user is mostly a bad decission, cause even if the user is not able to read information might be usefull. The better way is always to sign the entry as an entry with different language and offer automated translation possibility. Where it could make sense to hide content is if a user is doing a general search on contents, at least in order of the search results.
