Integrating Zend with CodeIgniter

Last day, I had to integrate Zend Framework with Codeigniter. This came out to be quite easier then i thought. So here are the steps for integrating zend
framework with codeigniter.

Step 1: Copy the Zend folder from inside the library folder of Zend Framework

Setp 2: Create a folder inside your system, such as ../system/zf.

Step 3: Create a helper file like: zf_helper.php and place it into ../system/application/helpers/
Here is the code for zf_helper.php file

    //For Linux OS
    ini_set('include_path', ini_get('include_path') . PATH_SEPARATOR . BASEPATH . '/zf/');
    require_once 'Zend/Loader.php';
    
    //For windows OS
    ini_set('include_path', ini_get('include_path') . PATH_SEPARATOR . str_replace('/', '\\', BASEPATH) . 'zf\\');
    require_once ('Zend/Loader.php');
?>

Step 4: Add this helper to your ../system/application/config/autoload.php file

    $autoload['helper'] = array('url', 'form', 'date', 'zf');   //zf is the helper that we have added for zend framework integration
?>

Step 5: Now you can use any modules of Zend Framework from CodeIgniter, like in a controller file

    class SomeTest extends Controller {
        //in some function
        //.....
        //....
        //....
        function someFunction() {
          //load Zend Classes
            Zend_Loader::loadClass('Zend_Gdata');
            Zend_Loader::loadClass('Zend_Gdata_Calendar');
            Zend_Loader::loadClass('Zend_Gdata_ClientLogin');
            Zend_Loader::loadClass('Zend_Http_Client');
            $username = "someuser@gmail.com";
            $password = "somepassword";
            $gCalen = Zend_Gdata_Calendar::AUTH_SERVICE_NAME;
            $client = Zend_Gdata_ClientLogin::getHttpClient($username, $password, $gCalen);
            $gCalen = new Zend_Gdata_Calendar($client);
            //and so on
        }
    }
?>

Get Google Calendar Events using cURL

Once i needed to get all the google calendar events to my site, i.e. getting all the events that we added to google calendar to our custom calendar. After some reading, i found some helpful tips for doing this and here is the code. This is just a snippet. For logging in to gmail account please check my other post. The authentication token obtained after successful login is used in the following code.
So, what this code does is, it gets google calendar events using cURL. The code is simple. Just the retrieving of xml feed of google calendar events is done here, after this we can parse the xml and display all the events to our custom page after some formatting. Checkout the code.

            $fAuth = "authentication-token-obtained-after-successful-login";
      $arr_headers = array();
      $arr_headers[] = "Host: www.google.com";
      $arr_headers[] = "MIME-Version: 1.0";
      $arr_headers[] = "Accept: text/xml";
      $arr_headers[] = "Authorization: GoogleLogin auth=".$fAuth;
      $arr_headers[] = "Content-type: application/atom+xml";
      $arr_headers[] = "Cache-Control: no-cache";
      $arr_headers[] = "Connection: Keep Alive \r\n";
     
      $url = "http://www.google.com/calendar/feeds/emialadd%40gmail.com/private/full";
      $ch = curl_init();
      
      
     curl_setopt($ch, CURLOPT_REFERER, "http://google.com");
     curl_setopt($ch, CURLOPT_URL, $url);
     curl_setopt($ch, CURLOPT_HEADER, 0);
     curl_setopt($ch, CURLOPT_HTTPHEADER, $arr_headers);
   
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
     curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4b) Gecko/20040612 Mozilla Firebird/0.9");
     curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
     curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
     curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

      $resFin = curl_exec($ch);
      echo $resFin;
      ?>

Accordion style show/hide divs using jQuery

This is just a start, but thought it might be of some help to others, so posted the code snippet. The code uses class for divs and anchor tags. This is a simple demo of accordion like tabs, but i've just done show and hide of divs using jQuery selectors.
When a link above a div is clicked, the div immediately below the anchor tag is displayed and all other divs are hidden.
Some animation can also be used in place of just show hide.If none of other divs are displayed as block then the current div is not closed. And by default first div is displayed when page is loaded.
Check out the following code snippet

$(document).ready(function() {
   //display by default the first div content
   $(".acc:first").css('display', 'block');
   //attach click event to anchor tags
   $(".atest").click(function() {
      //check for the display block or none of the immediate div next to anchor tag
      var displayStatus = $(this).next().css('display');
      if(displayStatus == "block") {
         var otherDivsStatus = $(".acc").not($(this).next()).css('display');
         if(otherDivsStatus == "block") {      
$(this).next().hide('slow');
}
}
else {
//hide all the divs except for the current div
$(".acc").not($(this).next()).hide('slow');
$(this).next().show('slow');
}
});
});
/*
Just a test html, this can be changed as needed

   First Block
   

    This is first div
   
   Second Block
   

    This is second div
   
   Third Block
   

    This is third div

Check All - Uncheck All multiple checkboxes using jquery

Sometimes later, i had to check and/or uncheck multiple checkboxes having same name being displayed dynamically). I have one checkbox for Check/Uncheck All, and depending on that, i had to check or uncheck other checkboxes. And if any one of the checkboxes, besides main checkbox, was checked or unchecked, then i would have to check or uncheck the main checkbox as well.
The text i have writte here might seem little confusing than the original source code, but the main point is i had to check/uncheck multiple checkboxes at once. So here is the jquery code that i wrote for doing the same.

$(document).ready(function() {
   //get count of checkboxes with the same name
   var countBoxes = $("input[name='chkTest[]']").size();
   //move through each checkbox
   $("input[name='chkTest[]']").each(function() {
      $(this).click(function() { 
         //get the state, checked or not, i.e. true or false
  var state = $(this).attr("checked");
  //get the length of checked checkboxes
  var chkedLength = $("input[name='chkTest[]']:checked").length;
  //make the checked or unchecked state
  var chkAllState = (chkedLength == countBoxes) ? true : false;
  //now apply the state to main checkbox
 $("input[name='chkAll']").attr("checked", chkAllState);
      });
   });
   //this code checks or unchecks all sub-checkboxes depending on checked state
   $("input[name='chkAll']").click(function() {
      var chkAllStatus = $(this).attr('checked');
      $("input[name='chkTest[]']").attr("checked", chkAllStatus);
   });
});

Same height sub-divs using jQuery

Previous day i had to make height of all the child divs same. Actually i had 3 divs, with different height according to dynamic content, inside a main div, but i needed to make of all those child divs same irrespective of the content they had. So, i figured it out using s simple jquery code.
This code actually checks for a div that has maximum height, and then applies that max height to all the divs that is contained inside the main div. Check out the following code snippet.

//include your jquery.js file here
$(document).ready(function() {
   //make a new array for storing the heights temporarily
   var heightArr = new Array();
   //loop through each of the child divs of parent div, 
   //i've used class of div, but it can be replaced with id as well
   $(".mainDiv").children().each(function() {
      var divHeight = $(this).height();
      //push the height to array
      heightArr.push(divHeight);
      });
   //this is a function to get maximum value from an array
   Array.max = function(array) {
      return Math.max.apply(Math, array);
   }
   var maxHeight = Array.max(heightArr);
   //now apply the maxHeight to all the divs css
   $(".mainDiv").children().each(function() {
      $(this).css('height', maxHeight);
   });
});
