What to solve

For some moments, my site needs a content or keyword for dynamic run or request. Like the site of http://zonmine.com, call google trend once a day to gather the hot keyword in shopping (for 30 days and 7 days ). Then it uses the Gtrend keyword to search products in Amazon. The content will appear updating daily and easily go up to 2000-5000 products in few days.

Features

Get the google trend keywod and save as a JSON

Requirements

  1. PHP 5.1+ with curl which I used a Curl library ( https://github.com/philsturgeon/codeigniter-curl ) .
  2. CodeIgniter

Example

default call

$response = $this->create_trend_keyword( );

//return json ["ipod","tv","camera","xbox","sony","speakers","nikon","xbox 360","headphones","ipod touch"]

Instruction

  1. Put the Gtrend.php under codeigniter "application/libraries" and make sure you have the Curl.php or $this->curl funtion

  2. Loading the libraries by either one of the following way:
    a. Autoload 'config/Autoload.php' add a param in $autoload['libraries'] = array('Curl', 'Gtrend');
    b. 

    function __construct() {
    
parent::__construct();
    
$this->load->library('Gtrend');
    
}

    c. 
    $this->load->library('Gtrend');

  3. setup the JSON file data path : $config['data_base_path'] = 'www/data/';

  4. Call the library as follow :

 $result = $this->create_trend_keyword( ); //default is cat "0-18-78" => Shopping > Consumer Electronics, type TOP  
 $result = $this->create_trend_keyword( $category, $type );
  1. The keyword JSON is now stored as {data_base_path}/{Ymd_type_cat_}.json
    e.g. 20130901_TOP_0-18-78_.json
    Content :
["ipod","tv","camera","xbox","sony","speakers","nikon","xbox 360","headphones","ipod touch"]
