Zend Flash message

2012-01-19T16:53:00.004+05:30

For displaying flash message after certain event like, when user submit the page and need to show the success message in next request or in current request. For that Zend framework has a action helper FlashMessenger.

Here is a sample code that can used to flash the message.

Step 1: Add message to helper class in controller

$flash = $this->_helper->getHelper('FlashMessenger');
$flash->addMessage(array('success' => 'Posted message saved successfully' ));

Ste 2: Create View Helper to display message in layout

class Custom_View_Helper_FlashMessenger extends Zend_View_Helper_Abstract
{
 public function flashMessenger ($width = null)
  {
  $flash = Zend_Controller_Action_HelperBroker::getStaticHelper('FlashMessenger');

  #for message
  $message = array();
  
  if($flash->getCurrentMessages())
  {
   foreach($flash->getCurrentMessages() as $key => $msg)
   {
    $message[key($msg)][] = $msg[key($msg)];
   }

   $flash->clearCurrentMessages();
  }
  else if($flash->getMessages())
  {
   foreach($flash->getMessages() as $key => $msg)
   {
    $message[key($msg)][] = $msg[key($msg)];
   }
  }

  $str_msg = null;
  $style = '';

  if($width) $style = "style='width:".$width."px'";

  if(count($message) > 0)
  {
   foreach($message as $key => $arr_msg)
   {
              $key = ($key == 'error')?'errormsg':$key;

    $str_msg .= '';
    $str_msg .= '';

    foreach($arr_msg as $msg)
    {
      $str_msg .= rtrim($msg,'.'). "
";
    }
    $str_msg .= '
';
    $str_msg .= '
';
   }
    }

    return $str_msg;
 }

  public function hasMessage()
  {
      $flash = Zend_Controller_Action_HelperBroker::getStaticHelper('FlashMessenger');
    
      if($flash->hasMessages() || $flash->hasCurrentMessages())
          return true;
      else
          return false;
  }
}

Step 3: Display the message in layout


  echo $this->flashMessenger();

Now you can add your falsh message in you any controller and it will display in you layout.

Hope this helps someone.

Addthis and ajax response page

2011-08-22T16:59:00.003+05:30

There are lots of post regarding Addthis api usage for AJAX page. But none of the post worked perfectly for me. However i got some idea from all that posts to implement it. Here is my code, made little changes from different post.



var addthisScript = "http://s7.addthis.com/js/250/addthis_widget.js#domready=1";/>



function initAddthis(){

  if (window.addthis){

     window.addthis.ost = 0;

     window.addthis.init();

  }

}

When you load page using ajax for example (here i have used jQuery)

$.load('http://example.com/lists',function(){

$.getScript( addthisScript , function(){

initAddthis

});

Please let me know, does it work for you.

Zend Custom breadcrumb using XML file

2011-07-07T13:28:00.022+05:30

As we know a breadcrumb can be generated using Zend_Navigation easily. But this will apply only to navigation menu items, not for other extra actions (outside from menu). Here i have overwrite Zend Navigation breadcrumb view helper, so that a separate XML file can be used for breadcrumb.

To implement this there are 6 simple steps. I have used Custom_ as namespace either change it to any namespace that you have used in your application or add this namespace in you application.

Step 1 : Create Custom_BreadCrumb class by extending Zend_Navigation_Container


class Custom_BreadCrumb extends Zend_Navigation_Container
{
/**
* Creates a new bread container from zend navigation help
*
* @param array|Zend_Config $pages [optional] pages to add
* @throws Zend_Navigation_Exception if $pages is invalid
*/
public function __construct($pages = null)
{
if (is_array($pages) || $pages instanceof Zend_Config) {
$this->addPages($pages);
} elseif (null !== $pages) {
require_once 'Zend/Navigation/Exception.php';
throw new Zend_Navigation_Exception(
'Invalid argument: $pages must be an array, an ' .
'instance of Zend_Config, or null');
}
}
}

Step 2: Create an empty view helper class


class Custom_View_Helper_Breadcrumbs extends Zend_View_Helper_Navigation_Breadcrumbs{}

you can override some feature of breadcrumbs view helper inside this class.

Step 3: Create XML File name breadcrumb.xml inside application/config/breadcrumbs.xml

Step 4: Load breadcrumb in bootstrap


protected function _initViewHelpers() {
$this->bootstrap('layout');
$layout = $this->getResource('layout');
$view = $layout->getView();
#breadcrumb
$breadCrubmConfig = new Zend_Config_Xml(APPLICATION_PATH . '/configs/breadcrumbs.xml');
$breadCrumb = new Custom_BreadCrumb($breadCrubmConfig);
$view->breadcrumbs($breadCrumb);
}

Step 5: Now set the breadcrumb active state in super action controller class

Note: Super action controller class means, all the controller class in an application should extend this class.


$module = $this->_request->getModuleName();
$controller = $this->_request->getControllerName();
$action = $this->_request->getActionName();
$mca = $module.'/'.$controller.'/'.$action;
$activeBreadCrumbs = $this->view->breadcrumbs()->findBymca($mca);
$activeBreadCrumbs->active = true;

Step 6: Usage

Just paste this line in your layout

echo $this->breadcrumbs()->setSeparator(' » ');

Let me know does it works for you.

Facebook login or permission page redirect loop

2011-06-10T09:45:00.004+05:30

After 2 days of my head aching, i am able to find the problem of facebook login or permission infinite loop.

Actually the problem occurs when the facebook graph api ("makeRequest" function in base_facebook.php) make a curl request to https url then curl try to verify the ssl certificate and it returns false (specially in my case). So for quick fix, i have add

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);

just after curl_init. Hope it helps you. As it works for me.

Let me know if it works for you.

Mongodb and Zend Framework using Mongo php library

2011-04-04T15:28:00.001+05:30

Here you can use Mongodb(NoSql) database with Zend Framework using Mongo php library. I have created three classes Custom_Mongo_Instance, Custom_Mongo_Db and Custom_Mongo_Collection extending Mongo, MongoDB and MongoCollection respectively. So that you can overrides its methods easily.

First download mongo library for php from here

Step 1 : Custom_Mongo_Instanc


class Custom_Mongo_Instance extends Mongo
{
  public function  __construct( $server = "mongodb://localhost:27017",  $options = array("connect" => TRUE) ) {
      parent::__construct($server,  $options);
  }
}

Step 2 : Custom_Mongo_Db


class Custom_Mongo_Db extends MongoDB
{
  public function  __construct( Mongo $conn, $name ) {
      parent::__construct( $conn, $name );
  }
}

Step 3 : Custom_Mongo_Collection


class Custom_Mongo_Collection extends MongoCollection
{
 public function __construct ( $name, $db = null ){
  if($db == null) $db = Zend_Registry::get('mongoDB');
 parent::__construct ( $db , $name );
}

 public function insert( array $a, $options = array())
{
 $a['created'] = date('Y-m-d H:i');
 parent::insert( $a, $options);
}
}

Step 4 : Usage


$cnn = "mongodb://username:password@localhost:27017";
try{
  $mongo = new Custom_Mongo_Instance($cnn);
  $mongoDB = new Custom_Mongo_Db($mongo, "dbname");
}catch(Exception $e){echo $e->getMessage();exit;}

$collection = new Custom_Mongo_Collection("my_collection", $mongoDB);
$data['first_name'] = "Ritesh";
$data['last_name'] = "jha"
$collection->insert($data);

Thats all. Now you can check the data either using mongo console or some third party GUI admin tools.

RabbitMQ adapter for Zend Framework and Zend Queue using AMQP php library

2011-03-28T13:20:00.001+05:30

You can use this class as Zend_Queue adapter for RabbitMQ queue system using AMQP php library.

Download AMQP extension from here

To compile and install follow this link

There are three steps

Note: Here i have used Custom_ namespace for Zend. You can change the namespace as per your choice.

Step 1 (Create Adapter class)

);
}

public function isExists($name){}
public function getQueues(){}
public function count(Zend_Queue $queue = null){}
public function deleteMessage(Zend_Queue_Message $message){}

Step 2(Create Exchange Class)

{

}

Step 3(Overwrite Zend_Queue Class)

Usage:

Sending Message

try{

$queue = new Custom_Queue($adapter, $queueoptions);
$message = 'Testing queue';
if($queue->send($message))
 echo "Message published \n";
else
 echo "Not";

}  catch (Exception $e){echo $e->getMessage(); }

Receive Message


try{
$adapter = new Custom_Queue_Adapter_Rabbitmq($adapteroptions);
$queue = new Custom_Queue($adapter, $queueoptions);
$messages = $queue->receive($options);
}  catch (Exception $e){echo $e->getMessage(); }

jQuery autocomplete with caching and custom value selection

2010-11-02T12:58:00.000+05:30

Download jQuery library from jQuery site and its ui plugin for autocomplete from this link http://jqueryui.com/home

Define below function in any your js file. (ex: common.js) and then include it in your page.

/**
* Set autocomplete property
*/
function setAutoComplete(element_id, ajax_url, listener, cache_name, term_length)
{
if (element_id === undefined || ajax_url === undefined) return false;
if (listener === undefined) listener = 'itemselected';
if (term_length === undefined) term_length = 1;
if (cache_name === undefined) cache_name = 'itosa_ac_cache';

var cache = [];
cache[cache_name] = [];

$("#"+element_id).autocomplete({
source: function( request, response ) {
var term = request.term;
if ( term in cache[cache_name] ) {
response( cache[cache_name][ term ] );
return;
}
$(this).addClass('ui-autocomplete-loading');
lastXhr = $.getJSON( ajax_url, request, function( data, status, xhr ) {
cache[cache_name][ term ] = data;
if ( data != null && xhr === lastXhr ) {
response( data );
}
});
},
minLength: term_length,
select: function(event, ui){$('body').trigger(listener,[event,ui]);}
})

return false;
}

When you select item from list it will trigger listener event, you have passed through function parameter "listener".

To access the code

setAutoComplete('search_person','http://example.com/person.php','personselect');
$('body').bind('itemselected',function (event,input_event,ui){
$('#seach_key').val(ui.item.id);
return false;
});

current.attr("box_h", current.height());
if(current.height() <= sliderHeight) $('#readmore_cnt').hide(); }); $(".slider").css("height", sliderHeight+ "px"); $(".slider_menu").click(function() { openSlider() }) }); function openSlider() { var open_height = $(".slider").attr("box_h") + "px"; $(".slider").animate({"height": open_height}, {duration: "slow" }); $(".slider_menu").html('');
$(".slider_menu").removeClass('view-more');
$(".slider_menu").addClass('view-less');
$(".slider_menu").unbind("click");
$(".slider_menu").click(function() { closeSlider() });
}

function closeSlider()
{
$(".slider").animate({"height": sliderHeight+ "px"}, {duration: "slow" });
$(".slider_menu").html('');
$(".slider_menu").removeClass('view-less');
$(".slider_menu").addClass('view-more');

How to get past date from today

2010-07-28T16:43:00.000+05:30

Here is the code,

$today = strtotime(date('y-m-d'));

for($i=0; $i < 7;$i++)

{

$days[] = date('y-m-d:l',($today-($i*24*60*60)));

}

print_r($days);die;

Output:

Array (

    [0] => 10-07-28:Wednesday

    [1] => 10-07-27:Tuesday

    [2] => 10-07-26:Monday

    [3] => 10-07-25:Sunday

    [4] => 10-07-24:Saturday

   [5] => 10-07-23:Friday

   [6] => 10-07-22:Thursday

Note: The result might be different as your testing date will be different.

PHP Reading PO file (the file generated from php source)

2010-02-08T15:27:00.003+05:30

Hi Guy's,

Here is the code for parsing PO file for editing in PHP. I have little modified the Drupal's code.


/**

Convert PHP source file to PO file

2010-01-26T14:43:00.001+05:30

I have written a simple code for generating PHP source code to PO file. I hope it may help you.

Here $file is your php file path (ex c:/my_file/test.php) with message content as __('your message in php code');


$msg_lines = "";
$po_obj = new POContent();
$po_obj->generatePoContent($file,$msg_lines);

#write po file content
$po_strings = "";
foreach($msg_lines as $msgid => $line_contents)
{
   $po_strings .= "#  Translator comments\r\n";
   $po_strings .= "#. Programmer comments\r\n";
   foreach($line_contents['line'] as $key => $line)
       $po_strings .= "#: ".$line."\r\n";
   $po_strings .= "msgid \"".$msgid."\"\r\n";
   $po_strings .= "msgstr ''\r\n";
   $po_strings .= "\r\n";
}
 
   $po_file_path = 'c:/my_file/test.po';
   $fh = fopen($po_file_path,'wb');
   if (!$fh) {
       echo __('PO File generation failed');
   }
   else{
       fwrite($fh,$po_strings);
       fclose($fh);
       echo __('PO File generated successfully');
   }

class POContent{
/**
    * Generate PO File by reading entire particular component's source file
    * @param $file String (PHP Source file path to parse)
    * @param $msg_lines String (Refrence variable to store all the msgid)
    * @return
    */
   function generatePoContent($file,&$msg_lines){
       //open source file
       $datas     = file($file);
       $msg_file = basename($file);
       $pattern  ="/__\([\"\']([^()]+)[\"\']\)/";
  
       foreach($datas as $indx => $data){
           $msgs = "";
           preg_match($pattern, $data, $msgs);
           if(count($msgs) > 0){
              if(!array_key_exists($msgs[1],$msg_lines)){
                  $msg_lines[$msgs[1]]['file'][$msg_file] = $msg_file.":Line No.".($indx+1);
                  $msg_lines[$msgs[1]]['line'][] = $msg_file.":Line No.".($indx+1);
              }
              else{
                  $temp_line = $msg_lines[$msgs[1]]['file'][$msg_file];
                  if(!array_key_exists($msg_file,$msg_lines[$msgs[1]]['file'])){
                   $msg_lines[$msgs[1]]['file'][$msg_file] = $msg_file.":Line No.".($indx+1);
                   $msg_lines[$msgs[1]]['line'][] = $msg_file.":Line No.".($indx+1);
                  }
                  else{
                   $msg_lines[$msgs[1]]['file'][$msg_file] = $temp_line.",".($indx+1);
                   $msg_lines[$msgs[1]]['line'][count($msg_lines[$msgs[1]]['line'])-1]=$temp_line.",".($indx+1);
                  }
              }
           }
       }
   }
}

Now You can check the c:/my_file/test.po
