Recruitment System – One of my projects

I wanted to post this since a while.

The recruitment system is one of the applications I built for cha-international while working there beside developing the Middle East & North Africa travel awards system, mail marketing system, and converting all their servers from windows to Linux.

In brief the system has the following features :

  • Backend :
  1. Managing countries, Nationalities, Languages, World Areas, System Announcements.
  2. Managing Education Levels, Industries, Titles, Departments, System Reply Messages, Candidate Status, Candidates Classifications, and Quotes.
  3. Testimonials section where the company can post its clients testimonials to be displayed in the frontend.
  4. Managing 2 types of resumes : Uploaded Attachments, and Detailed filled forms Resumes.
  5. Easy form for the data entry team to add the resumes from the backend.
  6. Searching for candidates, using simple forms like name, email or advanced one which contains name, different nationalities, different languages, age, sex, industry, title, keyword in resume, etc.
  7. Consultants area where they can post / close job posting, search  for candidates, export word version of resumes, add to their favorite list, recommend them to another consultant.
  8. Consultants also can comment on the resumes, change their availability status to be seen by other consultants, and communicate with the candidate through the reply messages and keep track of those sent messages.
  9. The system has a approval workflow engine, the admins have to check the resume to approve it first.
  10. The system has a privileges section where the administrator can create a new role, assign access to certain areas in the backend to certain role, and assign the roles to system users.
  11. Feedback system where the backend users can communicate with the administrator for support tickets, etc.
  12. Auditrail system where every action in the system is logged.
  • Frontend:
  1. Simple upload form where users can just upload their resume and simple details.
  2. Advanced profile form where users can fill in all the details, and add many attachments to their profiles.
  3. Listing, Simple search, advanced search for jobs, and applying to them.
  4. Clients area where they can request certain services.
  5. Featured profiles, where a certain profiles selected by the admins showed in frontend.

The project was completely built from scratch using Zend Framework, and right now it has more than 70,000 applicant in its database, and the system is as fast as you see in the videos, these demos were taken with 50,000 record in the database.

Please don’t give me any feedback on the design ;) , I am just a developer.

Here is some videos describing the different features of the system, I will try to post a better quality ones later.

PHP is Now

Lots of people asks the question why php, i guess this article titles “PHP is Now” by Cal Evans is the Director of the PHP Center for Expertise at Ibuildings, will help those who asks, to know what is the powers of this great tool.

article URL: http://www.ibuildings.com/blog/archives/1554-PHP-is-NOW.html

Why using PHP ?

PHP is one of the most popular server side scripting languages running today. It is used for creating dynamic WebPages that interact with the user offering customized information. PHP offers many advantages; it is fast, stable, secure, easy to use and open source (free).

Rasmus Lerdorf wrote the first PHP (first called Personal Home Page) scripts as a series of Perl scripts that he used to track visitors to his webpage and to see who was viewing his resume. He eventually rewrote PHP as a scripting engine and added support for forms. PHP has been evolving since 1994 as an open source code. A community of followers and developers formed and began using and further developing PHP. Over the years the Personal Home Page acronym was dropped and it evolved into the PHP Hypertext Preprocessor.

PHP code is inserted directly into the HTML that makes up a website. When a visitor comes to the website, the code is executed. Because PHP is a server side technology, the user does not need any special browser or plug-ins to see the PHP in action.

The beauty of PHP lies in its simplicity. It is easy to understand and learn, especially for those with backgrounds in programming such as C, JavaScript and HTML. The language is similar to C and Perl so that anyone with a background in either C or Perl programming will feel comfortable using and understanding PHP. PHP also runs on just about every platform including most UNIX, Macs and Windows versions.

PHP doesn’t use a lot of the system resources so it runs fast and doesn’t tend to slow other processes down. It is typically used as an Apache module, written in C, so it loads and executes quickly. It works well with other software and can be quite fast. PHP is also stable and since it is open source, the PHP community works together to fix any bugs. The community offers technical support and continuously updates the code further expanding PHP’s capabilities.

PHP offers many levels of security to prevent malicious attacks.

Another key advantage of PHP is its connective abilities. PHP uses a modular system of extensions to interface with a variety of libraries such as graphics, XML, encryption, etc. In addition, programmers can extend PHP by writing their own extensions and compiling them into the executable or they can create their own executable and load it using PHP’s dynamic loading mechanism.

In addition to extensions, PHP has tons of server interfaces, database interfaces and other modules available. Of the server interfaces, PHP can load into Apache, Microsoft IIS, Roxen, THTTPD and AOLserver. It can also be run as a CGI module. Database interfaces are available for MySQL, Microsoft MS SQL, Informix, Oracle and plenty of others. If a database is not supported, ODBC is an option.

The main PHP source repository is loaded with modules and interfaces that users have written and contributed. There you can find modules for flash movies, PDF files, calendars and more.

A huge advantage that PHP offers is its community. Since PHP is an open source project, the PHP community is willing to share.

PHP is the best choice for developing WebPages & Intranet applications, it is compatible with any database, and web servers, and integrates well across many platforms and with various software
programs.

Below is a diagram from Oracle.com comparing between PHP & ASP.net

For the above reasons this is why i choose and recommend for you PHP as its primary language for Web Space & Intranet Applications.

Smart Debugging with Zend Framework

Sometimes your clients report to you Errors you have never experienced while testing your web application, or broken links, or some errors that occurs under some scenarios that you didn’t apply.

There is a smart trick i do in the ErrorController in my Zend Framework applications, i make the application send me the same error it displays to the user direct to my email, so i can know under what circumstances and conditions that error occurred.

The sweet thing is that when google bot or any search engine crawls my websites, they find some errors also, errors that i and the client didn’t reach, so i get the chance to fix it before any body see it.

I also sometimes disable viewing the error message and display “Some errors has occurred and the support has been notified, sorry for the inconvenience” and provide a link to go to Homepage for example.

Below is the code i have in my ErrorController :

    $errors = $this->_getParam('error_handler');
        switch ($errors->type) {
            case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_CONTROLLER:
            case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_ACTION:
                // 404 error -- controller or action not found                
                $this->getResponse()->setRawHeader('HTTP/1.1 404 Not Found');
                $this->view->title = 'HTTP/1.1 404 Not Found';
                break;
            default:
                // application error; display error page, but don't change                
                // status code
                $this->view->title = 'Application Error';
                break;
        }
        $body = 'HTTP/1.1 404 Not Found' . "<br>";
        $body .= $errors->exception . "<br>";
        $body .= "IP Address: " . $_SERVER['REMOTE_ADDR'] . "<br>";
        $body .= "User Agent: " . $_SERVER['HTTP_USER_AGENT'] . "<br>";
        $body .= "Lang: " . $_SERVER['HTTP_ACCEPT_LANGUAGE'] . "<br>";
        $body .= "Referer Link: " . $_SERVER['HTTP_REFERER'] . "<br>";
        $body .= "Requested URL" . $_SERVER['REQUEST_URI'] . "<br>";
 
 
 
		$mail = new Zend_Mail();
		$mail->setBodyHtml($body);
		$mail->setFrom('support@somesite.com', 'Website Support');
		$mail->addTo("ahmed.abdelaliem@mysite.com.com", "Ahmed Abdel-ALiem");
		$mail->setSubject('Sitename Error Occurred');
		$mail->send();
 
 
 
        $this->view->message = $errors->exception;

Build MySQL insert Query from Array that contains fields and values

The following function takes table name, and array where its keys are the table fields and it’s values are the values to insert in each field, it constructs the MySQL Query based on the input and executes it to insert the data.

function insertRow($table_name, $input_array){
	$link = mysql_connect(SERVER, USER, PASS);
	mysql_select_db(DATABASE, $link);
	$SQL = "INSERT INTO $table_name ";
	$fields = "(";
	$values = "(";
	foreach ($input_array as $k => $v) {
		$fields .= "`$k` ,";
		$values .= "'$v' ,";
	}
	$fields .="#";
	$values .="#";
	$fields = explode(",#", $fields);
	$fields = $fields[0];
	$values = explode(",#", $values);
	$values = $values[0];
	$fields .= ")";
	$values .= ")";
	$SQL .= $fields . " VALUES " . $values;
	mysql_query($SQL);
	mysql_close($link);
}

List array Recursively in PHP

Code :

function listArrayRecursive($array_name, $ident = 0){
	if (is_array($array_name)){
		foreach ($array_name as $k => $v){
			if (is_array($v)){
				for ($i=0; $i < $ident * 10; $i++){ echo "&nbsp;"; }
				echo $k . " : " . "<br>";
				listArrayRecursive($v, $ident + 1);
			}else{
				for ($i=0; $i < $ident * 10; $i++){ echo "&nbsp;"; }
				echo $k . " : " . $v . "<br>";
			}
		}
	}else{
		echo "Variable = " . $array_name;
	}
}

Usage :

$ages = array(
				"ahmed" => "25",
				"mohamed" => "35",
				"group" => array("omar" => "15", "abdalla" => "20", "sub group" => array("john" => "10", "peter" => "20")));
 
listArrayRecursive($ages);

Output will be printed array in indented way.

Render Nothing in Zend Framework

This is useful if u want to have the output without rendering a view or the layout, like in ajax or developing we services

to do that you need to call the following 2 methods in your Action :

$this->_helper->viewRenderer->setNoRender(); // Disable the viewscript
$this->_helper->layout->disableLayout();  // Disable the layout

Zend Framework Free Book : Surviving The Deep End

Hey folks,
today Padriac Brady has released a new Zend Framework Book,

About the author :
http://www.survivethedeepend.com/zendframeworkbook/en/1.0/introduction#zfbook.introduction.me

To read the book :

http://www.survivethedeepend.com/zendframeworkbook/en/1.0

About the book (quoted from the book):

Zend Framework: Surviving The Deep End is written in the form of a detailed tutorial following a step by step approach to building a real life application. Topics are grouped where it makes sense and there will be continual references to earlier chapters which serves to reinforce what you’re learning as you read. The book was designed to bring together elements of the Reference Guide, the growing body of community knowledge and my own personal experience so developers can see the bigger picture of developing a real application with the Zend Framework.No comments

To my mind that’s always been the framework’s main problem since the Reference Guide adds little beyond explaining each framework component in total isolation. It doesn’t offer a development approach, ways of thinking or a list of advanced topics which combine components. You should note though that this book is not a replacement for the Zend Framework Reference Guide. It’s assumed you can do some independent reading of the Reference Guide. The Guide is free, detailed, and reasonably easy to search. This book is a complement to it, not a replacement.No comments

The book also includes the full source code of the application within the text, and may repeat it several times to highlight new changes I am making. I understand that pages of source code can sometimes be frustrating but it does enforce clarity and I value clarity a great deal. For simplicity the full finalised source code of each chapter is available as a separate internet download.No comments

I will over time refer to several external libraries, other than the Zend Framework, which you are expected to install. These will include PEAR, Blueprint CSS Framework, jQuery, HTMLPurifier and PHPUnit. I know from experience this can be unpopular with some people but I assure you that their installation will be covered in detail and is quite straightforward even for beginners. You should bear in mind a real life application will require numerous external libraries!No comments

Finally, note that this book assumes a basic working knowledge of PHP 5, SQL, and Object Oriented Programming (OOP). These are necessary skills if you intend learning the Zend Framework but will not be covered by this book in detail. Since PHP is so simple to learn though, I don’t doubt you can find countless resources online to get you started down the road towards PHP Guru status.

Appcelerator :: Building RIA Apps and Use Cases with ease

Yesterday i was browsing Zend Framework Webinars, and i stopped by the title :

Get “Rich” Quick : Building Ajax-based RIAs with the Zend Framework and Appcelerator

i didn’t hear about the Appcelerator thing before, but the title was really interesting as i use Zend framework extensively and it is a great idea to add some interactivity and UI to my apps.

after watching the webinars, i really liked the idea of being able to build the full prototype and have it working with no server side code, and then in the development phase with some slight changes to the prototype, it becomes the working front end interacting with the server side code with no problems @ all.

i went to try.appcelerator.org and gave it a try on the fly, that got me more interested. so i downloaded the sdk installer for MAC and installed it, the installation was at ease, even creating the projects and testing.

Appcelerator supports what we call “technology driven agile development” and we call that process Interactive Use Cases.
