Yii Framework – introduction and more

Shaked — Sun, 06 May 2012 23:39:44 +0000

Description

yiiframework.com:

Yii is a high-performance PHP framework best for developing Web 2.0 applications.

Yii comes with rich features: MVC, DAO/ActiveRecord, I18N/L10N, caching, authentication and role-based access control, scaffolding, testing, etc. It can reduce your development time significantly.

Requirements

Yii supplies an easy way to know what kind of modules and such are required to use its power.

Requirements are available at http://your-domain/path/to/yii/requirements/ and should look like the following:

Installation and a tour

Yii does not require installation, yii documentation provides a well explained 'take a tour' page which let you generate your first 'hello world' page.

How to

So the question is how to do what? There are two topics which I want to write about today:

Layouts
Assets Manager

Layouts

Layouts are usually an important feature which should be a part of (almost) any MVC framework.

Yii framework provides us a easy way to use layouts:

Create new .php file in protected/views/layouts/your_new_layout.php
Add your relevant data, while $content reflects the rendered data:
....
Change your layout by requirements for each controller action or for the entire controller by using:
$this->layout = 'your_new_layout';
Should be look like this:
function actionIndex(){
$this->layout = 'your_new_layout';
}

That's it! easy, ha ?

Assets Manager

Yii framework provides a very nice way to handle assets. The thing which I like the most is where do I put my assets declarations.

I saw many ways to declare about assets:

Part of the controller
Part of the HTML (inline)
Both
Weird ways which I should not even mention

In my perspective, assets declaration should be part of the HTML by using PHP (or any other template system\language), for example:

getClientScript();
$clientScript->registerScriptFile('//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js');
$clientScript->('API.js',CClientScript::POS_END); 

//load css
$clientScript->registerCssFile('//ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/themes/start/jquery-ui.css');
$clientScript->registerCssFile($baseUrl.'/css/events.css');

?>

More HTML here

As you can see, I declared both JS and CSS in my HTML file , so why ?

As I see it the developers which should maintain the way we use our assets are the front-end developers.

Implementing the above code won't be enough when working on a live environment, therefor we have to solve it by using JS and CSS minifiers.
This guide might not bring the best way to do that since I just want to prove my point, so please share your ways to do that.

To minify my assets I'v used DynamicRes extension with the following steps:

Download the extension and install it into protected/extension/

Add the following to protected/config/main.php:

// application components
'components'=>array(
..
..
//@see http://www.yiiframework.com/extension/dynamicres/
		  'dynamicRes'=>array(
            'class' => 'ext.DynamicRes.DynamicRes',
            'urlConfig' => array( // Its fix Css, and convert Url to RealName
                'baseUrl'  => '/', // Url of your Site (ending with /), modify it if you use subdomain
                'basePath' => dirname(__FILE__).'/../../', // path of your site (ending with /) (No Change This)
            )
          ),
..
..

Replace Yii::app()->getClientScript() with Yii::app()->dynamicRes
You may add your env param to make your structure more dynamic

My final implementation looks like this:

/**
* ENV Settings

* TODO: should be move to Yii::app() to return ClientScript by ENV settings
 */
if (Yii::app()->params['env'] == 'dev'){
	$baseUrl = Yii::app()->request->baseUrl;
	$cs = Yii::app()->getClientScript();
} else {
	$baseUrl = '';
	$cs = Yii::app()->dynamicRes;
}
//load it from google cache so no need to pack and minify
Yii::app()->getClientScript()->registerScriptFile('//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js');

	$cs->registerScriptFile($baseUrl . '/js/external/underscore.js'			,CClientScript::POS_END); 

	$cs->registerScriptFile($baseUrl . '/js/external/Backbone.js'			,CClientScript::POS_END); 

	$cs->registerCssFile($baseUrl.'/css/style.css');

Summary

Yii framework is an interesting toolbox which I ll continue to explore.

In my upcoming posts I ll write about memcache, modules and more.

Feel free to write\suggest\ask anything that comes in mind.

JIRA cannot start its required plugins

Shaked — Tue, 13 Mar 2012 00:17:14 +0000

Desription

Seems that JIRA might suddenly crashes once a while.

When JIRA crashes, it won't remove the "JIRA lock" and then you won't be able to use it.

One of (many) reason that this problem might happen is due the lack of time that JIRA has to run its required plugins.

Log file might show:

Creating Chrome user profiles

Shaked — Sat, 11 Feb 2012 18:35:14 +0000

Description

Google Chrome finally supports "Chrome profiles"

Why do I need it?

Finally useful tool for people who share their computer with other OR wants to have multiple profiles over the same computer for testings.

How

Its very easy to create new profile and manage the existing one:

Download Chrome
Go to "Chrome control" menu
Open "Preferences"
Go to "Personal Stuff"
Click on the "add new user"
Now you can manage your accounts through the icon on the top left (right for RTL languages) by clicking and choosing the relevant user.
Good luck!

Notes

Creating new profile doesn't mean that your password are safe, as I noticed that my users and password are still available on other profiles as well!

Enjoy

Zend Framework, Gmail, SMTP and SSL

Shaked — Sat, 21 Jan 2012 20:13:09 +0000

Topic says everything, isn't it?

Description

I had a problem sending emails while using Zend Framework with Gmail account. So I had to handle different types of errors:

"Unable to connect via TLS" - being created by Zend Framework Exception.
"Unable to find the socket transport "https" - did you forget to enable it when you configured PHP?" - PHP built in error message

Suggestions

Before starting to code, you have to configure your PHP to work with php-openssl.

Linux:

Install openssl

Install php5_openssl. I`m not sure about all of the distributions I did it only on OpenSuse:

zypper install php5_openssl

I`m guessing that on CentOS it would be something like

yum install php5_openssl

And Ubuntu

apt-get install php5_openssl

Windows:

Add extension=php_openssl.dll to your php.ini

After finishing it, please restart your apache.

Now check if the SSL module is installed:

php -m | grep ssl

will output:

openssl

Or try to check your phpinfo.

Now you can use my code as an example:

application.ini

email.host 			= 'smtp.gmail.com'
email.from		 	= 'info@yourdomain.com'
email.name 			= 'Display Name'
email.params.auth		= 'login'
email.params.username 		= 'info@yourdomain.com'
email.params.password 		= 'Password'
email.params.ssl 		= 'ssl'
email.params.port 		= 465

helper.perfix[] = 'My_Helper';

Bootstrap.php

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
    protected  function _initConfig(){
    	 $config = new Zend_Config_Ini(
            APPLICATION_PATH . '/configs/application.ini',
            APPLICATION_ENV
        );
        Zend_Registry::set('appConfig',$config);
    }
    protected function _initHelpers(){
    	 $perfix = Zend_Registry::get('appConfig')->helper->perfix->toArray();
    	 Zend_Controller_Action_HelperBroker::addPrefix($perfix[0]);
    }
}

IndexController.php

class IndexController {
 	public function indexAction(){
		$helper = $this->_helper->mail(array(
				 			'email'		=> 'myemail@gmail.com',
				 			'subject' 	=> 'test subject',
				 			'message'	=> 'just a test message'
				 		));
		var_dump($helper);die;
	}
}

				));
			}
		}
	}

		return $this->_mail->send($transport);
	}
}

Summary

Using Zend Framework is pretty straight-forward when you have all of your server settings enabled.

You are more then welcome to update me if you would found any other solution or a problem.

WordPress – avoiding wpautop method

Shaked — Sun, 08 Jan 2012 09:11:16 +0000

Long time ha?

So I`m working on a WordPress plugin for a while, and I found some common issues with plugins that need to be integrated with WordPress's posts.

One of the main issues is the wpautop method.

Description

From WordPress's website:

Changes double line-breaks in the text into HTML paragraphs (
...
).

WordPress uses it to filter the content and the excerpt.

Now lets dig a bit more inside ha?

function wpautop($pee, $br = 1) {
        if ( trim($pee) === '' )
                return '';
        $pee = $pee . "\n"; // just to make things a little easier, pad the end
        $pee = preg_replace('|
\s*
|', "\n\n", $pee);
        // Space things out a little
        $allblocks = '(?:table|thead|tfoot|caption|col|colgroup|tbody|tr|td|th|div|dl|dd|dt|ul|ol|li|pre|select|option|form|map|area|blockquote|address|math|style|input|p|h[1-6]|hr|fieldset|legend|section|article|aside|hgroup|header|footer|nav|figure|figcaption|details|menu|summary)';
        $pee = preg_replace('!(<' . $allblocks . '[^>]*>)!', "\n$1", $pee);
        $pee = preg_replace('!()!', "$1\n\n", $pee);
        $pee = str_replace(array("\r\n", "\r"), "\n", $pee); // cross-platform newlines
        if ( strpos($pee, ']*)>\s*|', "", $pee); // no pee inside object/embed
                $pee = preg_replace('|\s*\s*|', '', $pee);
        }
        $pee = preg_replace("/\n\n+/", "\n\n", $pee); // take care of duplicates
        // make paragraphs, including one at the end
        $pees = preg_split('/\n\s*\n/', $pee, -1, PREG_SPLIT_NO_EMPTY);
        $pee = '';
        foreach ( $pees as $tinkle )
                $pee .= '' . trim($tinkle, "\n") . "\n";
        $pee = preg_replace('|\s*|', '', $pee); // under certain strange conditions it could create a P of entirely whitespace
        $pee = preg_replace('!([^<]+)!', "
$1
", $pee);
        $pee = preg_replace('!\s*(]*>)\s*!', "$1", $pee); // don't pee all over a tag
        $pee = preg_replace("|(|", "$1", $pee); // problem with nested lists
        $pee = preg_replace('|
]*)>|i', "
", $pee);
        $pee = str_replace('
', '', $pee);
        $pee = preg_replace('!\s*(]*>)!', "$1", $pee);
        $pee = preg_replace('!(]*>)\s*!', "$1", $pee);
        if ($br) {
                $pee = preg_replace_callback('/<(script|style).*?<\/\\1>/s', '_autop_newline_preservation_helper', $pee);
                $pee = preg_replace('|(?)\s*\n|', "
\n", $pee); // optionally make line breaks
                $pee = str_replace('', "\n", $pee);
        }
        $pee = preg_replace('!(]*>)\s*
!', "$1", $pee);
        $pee = preg_replace('!
(\s*]*>)!', '$1', $pee);
        if (strpos($pee, ']*>)(.*?)

!is', 'clean_pre', $pee ); $pee = preg_replace( "|\n

$|", '

', $pee ); return $pee; }

You may find more at http://core.trac.wordpress.org/browser/tags/3.3.1/wp-includes/formatting.php

As you can see, this function changes a lot of things in WordPress's posts, such as:

Adding \n after (almost) each HTML tag
Fixing new lines to cross platform newlines (\r\n to \n)
Changing the tag
Adding
tags.
Cleaning empty
```
 tags
```

So I marked the most important issue about this function "Adding

tags".

Why is it so important for me?

As I wrote before it seems that one of the biggest problems for developers that develop WordPress plugins is the wpautop plugin. When they are trying to modify the user's posts, they always need to struggle with the

tags and sometimes they don't know how to handle them right.

Suggestions...

What to do

If I remember correctly , wpautop priority is set to 11 by default.

I have split my solution into 4 steps:

Mark your posts with your own "signature"
Create your own HTML template and don't use
tags
Changing the_posts
Removing the
tags from my plugin's HTML

How?

Marking your posts:

Include special statement inside post_content, for example when adding new post you may add a text "my-plugin-text-needs-to-be-manipulated", so the user's post will look like:

This is a new post

my-plugin-text-needs-to-be-manipulated

Thank you all!

Changing the posts:

	public function manipulate($posts){
		$newPosts = array();
		foreach ($posts AS $post) {
			if (false === strpos($post->post_content,self::TEXT_TO_CHANGE)
				 || !self::IsPreviewMode($post->ID)){
				$newPosts[] = $post
				continue ;
			}

			//remove new lines
			//TODO: extract your data to your HTML (real plugin uses a View object and render's the data)
			$html = str_replace("\n","",file_get_content("some.html"));
			//assign back to post content
			$post->post_content = str_replace(self::TEXT_TO_CHANGE,$html,$post->post_content);
			$newPosts[] = $post;
		}
		return $newPosts;
	}

	/**

	private static function IsPreviewMode($postID){
 		return isset($_GET['preview']) && isset($_GET['p']) && $_GET['p'] != $postID;
	}
}

$posts = new Posts;

	$dom = new Extended_DOMDocument($content);
	$content = $dom->removeWpAutoP();
	return $content;
}

What not to do

It's pretty easy -don't remove the filter.

Why?

Because removing the filter most of the time creates bugs and problems with other posts and plugins. For example, when disabling the function you would notice that sometimes the post won't have any newlines at all.

Summarize

Using WordPress's wpautop making our life very hard. As I see it, WordPress should give their developers more freedom while writing their plugins.
This might not be the most useful way to write this fix, but then you may ask if its useful to use WordPress

Some of the functions were found on Google or in different websites, I didn't write them all although I did write the "logic". I have tried to keep my sources written in the code's comments (such as stackoverflow), so if you would find something that belongs to you, please contact me to add your name or remove the script.

Hope this guide will help other as it helped me.

PHP Managing zip files with ZipArchive

Shaked — Sun, 18 Dec 2011 01:17:44 +0000

Requirements

PHP 5.2 or greater (would be a bit sad to know that someone is still using PHP 4)
Upgrade PEAR to latest version
Upgrade PECL to latest version
Installing PHP ZipArchive library by using PECL's zip package

Installation

I will use pecl to install ZipArchive PHP library.

Open terminal and execute pecl install zip
Updating your php.ini:

Linux: find your php.ini file and add "extension=zip.so"
Windows: same as one, just add "extension=zip.dll"

Restart httpd\apache

service httpd restart
apache2ctl restart
or any other way that you like

Usage Example

There are many different ways to use and build Zip helpers. I will just demonstrate an example for using ZipArchive.

Pastebin: http://pastebin.com/J2M0jjQG

Did you define your PHP extension directory correct ?
Windows and *NIX system works different by using the opposite slash "/"(*NIX) or "\"(Windows) - my solution is to use sprintf()

Downloading the script sometimes requires to send some different header, the following example was taken from the stackoverflow link above:

header("Cache-Control: public");
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
//header("Content-Description: File Transfer");
//header("Content-type: application/zip");
header("Content-Disposition: attachment; filename=\"YOUR_FILE_NAME_HERE.zip\"");
//header("Content-Transfer-Encoding: binary");
header("Content-length: " . filesize($filename));

How to find your php.ini file

Shaked — Sun, 18 Dec 2011 00:15:03 +0000

Finding your php.ini is pretty straight forward task:

open terminal or cmd
execute php --ini if php is undefined you should add it to your PATH or just execute "/your/path/to/php --ini"
php.ini has several modes (path is different sometimes...):

using one file:
Configuration File (php.ini) Path: /etc/php5/cli
Loaded Configuration File: /etc/php5/cli/php.ini
using several different files (will help to maintain common settings between cli php.ini and httpd php.ini
Scan for additional .ini files in: /etc/php5/conf.d
Additional .ini files parsed: /etc/php5/conf.d/ctype.ini,
/etc/php5/conf.d/curl.ini,
/etc/php5/conf.d/dom.ini,
/etc/php5/conf.d/gd.ini,
/etc/php5/conf.d/hash.ini,
............more .ini files here............

files content could be "extension=gd.so" (unix) or "extension=gd.dll" (windows)

there are two more options to get your ini files:

execute in cli mode: "php --i | grep .ini"
write your own script and check via browser:

That's it, now you can just edit your php.ini with anything you think you will need for future PHP programming.
More about php.ini may be found at http://php.net/manual/en/ini.php

MySQL Split String Function Fix (split_str)

Shaked — Wed, 23 Nov 2011 23:20:57 +0000

While working on one my projects, I was needed to use split_str function in MySQL. I Googled for it and found two answers (which are exactly the same - one is leading to the other):

Federico Cargnelutti - MySQL Split String Function

Stackoverflow - MYSQL - Array data type, split string

Everything worked great while using different delimiters, such as: "," , "||", "@@@", "###" or any other delimiter. I was using delimiters which their length > 1, exmaple:

select split_str(‘ABC,,BA,,abc’,',,’,3);
//result: “abc”

Seems good, ha? But then I`v noticed that there is a problem. When my full string contains two bytes characters (e.g: ¼), everything is breaking a part. Lets see the following exmaple:

select split_str(‘ABC¼,,BA,,abc’,',,’,3);
//result: “,abc” (delimiter was still there)

So how do we fix it? Seems that we need to change split_str function, all we have to do is to use CHAR_LENGTH() and not LENGTH(). There is a difference between those functions which you can read at MySQL.com website or just read the following quote:

CHAR_LENGTH(str)

Returns the length of the string str, measured in characters. A multi-byte character counts as a single character. This means that for a string containing five two-byte characters, LENGTH() returns 10, whereas CHAR_LENGTH()returns 5.

Enough talking. This is the function after my little fix:



CREATE FUNCTION SPLIT_STR(
  x VARCHAR(255),
  delim VARCHAR(12),
  pos INT
)
RETURNS VARCHAR(255)
RETURN REPLACE(SUBSTRING(SUBSTRING_INDEX(x, delim, pos),
       CHAR_LENGTH(SUBSTRING_INDEX(x, delim, pos -1)) + 1),
       delim, '');

Then using the same example I`v used above:



select split_str(‘ABC¼,,BA,,abc’,',,’,3);
//result: “abc”

I want to say thank to Federico Cargnelutti that helped us by writing the above function.

Setup\Configure Zend Debugger

Shaked — Sun, 20 Nov 2011 21:44:58 +0000

Using a debugger is very important while writing code, so lets see how to do it with PHP and Zend Debugger:

Install Eclipse or Zend Studio
If you have installed Eclipse, you should install two more things:

PDT (PHP Development Tools)
Zend Debugger

After extracting everything, search for ZendDebugger.so path

Edit your php.ini or create another ini --> zend.ini which will have to be loaded by your PHP and add:

; Loading Zend Debugger Extension
zend_extension=/your/path/to/ZendDebugger.so
;
; use 127.0.0.1 for local host, or you another local network IP
zend_debugger.allow_hosts=127.0.0.1
;
;
Expose Zend Debugger
;
;
never - do not expose (default)
;
always - expose to whoever want to know
;
allowed_hosts - expose only if request comes from an IP listed above
;
zend_debugger.expost_remotely=always

Save & Restart Apache
Verify your phpinfo()

Download FireFox or Chrome Extension (Chrome extension is not official extension by Zend)
Configure Eclipse \ Zend Studio settings:

Configure your extension settings:

Start debugging!:)

Helpful links:

cmanon.com

stackoverflow - PHP 5.3.5 and Zend Debugger

Note for Zend Studio 8.x users:

I suggest that you will update your Zend Studio application by using the following instructions:

Enjoy!

PHP: Insert\Update MySQL BIT(1) field

Shaked — Fri, 18 Nov 2011 21:03:00 +0000

Today I`v noticed to interested things:

A nice sentence or a motto that I really liked:
"When you do a search, and it comes back with no results, it’s a sign that you need to write something." (Taken from Here
Didn't find any straight answer on Google for my question: "How to insert\update a bit field with PHP":

So with MySQL you would use:

INSERT INTO t SET b = b'1'; // Or b'0'

And with PHP you would use boolean type:


//$db instanceof ActiveRecord, that's only for the following example
//you can use other ways to insert\update your MySQL DB. 

$db->insert(array('b'=>true,'c'=>false)); //true = b'1' , false = b'0'

$db->update(array('b'=>true,'c'=>false)); //true = b'1' , false = b'0'

Hope I helped,
Shak.
