Google Oauth2 library for CodeIgniter framework

Hello everyone,

I am back with google oauth2 integration library this time. Before you use the google oauth2 library you must have a google application registered so that you have access to api client id and client key which you will need to use it.

Also the redirect url must match your application location. Otherwise google does not provide access to the api. So, best way to test the code is to test it on a live site.

I am not going to go through the code here as I have commented the code well enough for you to understand :)

For any extra query feel free to comment.

DOWNLOAD THE LIBRARY

Codeigniter: Helper for template library dynamic view partial loading

Hello everyone,

I have recently been in quick-fire blogging mode. After playing with the superb template library developed by Phil Sturgeon.

The following template helper is the outcome of tweaking that makes life easier while setting up view partials and calling them inside the layout dynamically. The helper also has an add-on use which gives user the option to use region specific partial loading.

Controller:

welcome.php

$partial_list[]['region'] = 'left';
$partial_list[]['name'] = 'category';
$partial_list[]['view'] = 'partial_category';
$partial_list[]['region'] = 'right';
$partial_list[]['name'] = 'login_box';
$partial_list[]['view'] = 'partial_login';

/* following functionautomatically sets the partials
* based on the above array and also passes $partial_list
* variable to the view.
*/

/*
* make sure the pareser helper is loaded before
* calling this function
*/

setup_partials($partial_list);

$this->template->set_layout('home_layout');
$this->template->build('home_view');


Layout:

home_view.php

<html>
<head>
	<title><?php echo $template['title'];?></title>
</head>
<body>
	<div class="left">
		/* Will show only partials with region set as left */
		<?php show_partials('list', 'left', $partial_list, $template); ?>
	</div>
	<div class="mid"><?php echo $template['body'];?></div>
	<div class="right">
		/* Will show only partials with region set as right */
		<?php show_partials('list', 'right', $partial_list, $template);?>
	</div>
</body>
</html>

Detail about the usage can be found in the actual helper file, also feel free to comment here and I will try my best to help out.

Google translate helper for codeigniter

Hello everyone,

I am back with a tiny contribution. Today I have created a nifty helper for codeigniter which uses the google translate api (v2).

In order to use the function you will require a google translation api key which you can get for free the google api console (https://code.google.com/apis/console).

After you have your key it has to be passed to the function along-with the text to be translated, the language from which it is being translated from and to the language it is translated to. The function returns the translated text which can be used to do further processing or can be also be echoed.

CODE:

  1. <?php
  2.  
  3. /* Develeoped by: faisal ahmed <thephpx(at)gmail.com–> */
  4.  
  5.         function google_translate($api_key, $text, $from_lang, $to_lang){
  6.                 $link = ‘https://www.googleapis.com/language/translate/v2?key=’.$api_key.‘&amp;source=’.$from_lang.‘&amp;target=’.$to_lang.‘&amp;q=’.$text;
  7.                 $response = file_get_contents($link);
  8.                 $array = json_decode($response);
  9.                 return $array->data->translations[0]->translatedText;
  10.         }
  11.  
  12. ?>

Hope to be back with another snippet soon, till then keep in touch :)

thanks,

codeigniter: facebook social plugin – like button helper

Hello everybody,

I have just created a short helper to create facebook like button dynamically for any content, by just giving-in the URL of the page. Hope this one also helps you like my other helpers :)

Helper function:

  1.  
  2. if(!function_exists(‘facebook_like’)){
  3.  function facebook_like($url){
  4.  $formlink=‘<iframe src="http://www.facebook.com/plugins/like.php?href=’;
  5.   $formlink .= urlencode($url);
  6.   $formlink .= ‘;layout=button_count&amp;show_faces=true&amp;width=450&amp;action=like&amp;colorscheme=light&amp;height=21" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:450px; height:21px;" allowTransparency="true"></iframe>’;
  7.                
  8.   return $formlink;
  9.   }
  10.  }
  11.  

Usage:

  1.  
  2. <?php
  3. $url = current_url();
  4. echo facebook_like($url);
  5. ?>
  6.  

Note:
As you can see the function requires you to use the codeigniter’s native URI helper.

Codeigniter: Helper – Create breadcrumb from url

Breadcrumb is a navigational tool that developer often integrate in their application to give easy access to different segment of the application. This is used in applications which has multiple sequence of activities.

The following code will go into your helper file and you have to call create_breadcrumb(); function to get the formatted html text;

  1. if(!function_exists(‘create_breadcrumb’)){
  2. function create_breadcrumb(){
  3.   $ci = &amp;get_instance();
  4.   $i=1;
  5.   $uri = $ci->uri->segment($i);
  6.   $link = ‘<ul>’;
  7.  
  8.   while($uri != ”){
  9.     $prep_link = ”;
  10.   for($j=1; $j<=$i;$j++){
  11.     $prep_link .= $ci->uri->segment($j).’/';
  12.   }
  13.  
  14.   if($ci->uri->segment($i+1) == ”){
  15.     $link.=’<li>» <a href="’.site_url($prep_link).’"><b>’.$ci->uri->segment($i).’</b></a></li> ’;
  16.   }else{
  17.     $link.=’<li>» <a href="’.site_url($prep_link).’">’.$ci->uri->segment($i).’</a></li> ’;
  18.   }
  19.  
  20.   $i++;
  21.   $uri = $ci->uri->segment($i);
  22.   }
  23.     $link .= ‘</ul>’;
  24.     return $link;
  25.   }
  26. }
  27.  

If the current url is http://www.domain.com/user/add then the create_breadcrumb() function will return -

  1. » user » ad

Here user is linked to http://www.domain.com/user/ and add is linked to http://www.domain.com/user/add

This is generated by calling in the view file. Try it out and let me know how it went :)

thanks,

thephpx

Codeigniter: Helper – absolute path helper

Recently I decided to give some more time to my blog and write some short but interesting posts. I will be writing some posts about custom helper functions that I have written which helps me in application development.

First on the list is a absolute path helper which creates an absolute path, relative to the base of the application. I call this function base_path(‘relative/url’);

  1. if(!function_exists(‘base_path’)){
  2.     function base_path($relative_path_location){
  3.         return base_url().$relative_path_location;
  4.     }
  5. }

The above is the code which will go into your helper file. The function formulates an absolute url from the given relative path based on base path of the application directory. It uses the existing base_url() helper function in codeigniter. So, you have make sure the URL helper is already loaded.

Example:

Suppose you want to tag an image which is located at “application-root/images/picture.jpg” to give its absolute URL in the img tag you can type as follows in your template/view file.

  1. <img src="<?php echo base_path(‘images/picture.jpg’);?>" alt="picture"/>

If you application is hosted at domain.com then it will give http://www.domain.com/images/picture.jpg as the returned path where http://www.domain.com/ is the base_url();

thanks,

PHP Simple HTML DOM Parser, Codeigniter Integration

Hi all,

I came across “Simple HTML DOM Parser” recently that allows jQuery like DOM selection. This function is quite handy to do some kungfoo DOM manipulation on the fly!

I needed to use it on codeIgniter so modified the files and integrated it into a single codeIgniter library. The original files can be accessed from here its sourceforge project page. For the codeigniter version of the library click here.

  1. $this->load->library(‘domparser’);
  2. $html = $this->domparser->file_get_html(‘http://www.google.com/’);
  3. $rank = $html->find(‘b.gb1′);
  4.  
  5. print_r($rank); // will show all content of tag with class gb1

For further utility functions of the DOM parser visit this link.

Feel free to comment or contact me directly for any query.

take care,

thephpx
