The Bakery Everything CakePHP

Step1: create a file "/app/controllers/components/ir_weather.php" then copy below codes into it:


<?php 
/* Weather.ir API component for Cakephp
 * @author Vahid Alimohammadi http://cybercoder.ir
 * @version 1.0
 * Free 2 Use
*/
uses('Xml') ;
class IrWeatherComponent extends Object
{
    var $WEATHER_API_URL='http://weather.ir/farsi/RSS/xml.asp';
 
    /*
     * Get today weathers Xml file from weather.ir
     * return array|bool $results
    */
    function get_weathers()
    {
        if($this->content = file_get_contents($this->WEATHER_API_URL))
        {
            $weather_xml=& new Xml($this->content) ;
            $results=$weather_xml->toArray() ;
            return $results ;
        }
        else
        {
            $this->errors[]='Unable to connect to Weather.ir XML file. (output of http://weather.ir/farsi/RSS/xml.asp)';
            return false;
        }
    }
    
    function show_details($StationNo)
    {
        $weathers=$this->get_weathers() ;
        foreach ($weathers['Root']['Row'] as $weather)
        {
            if ($weather['StationNo']==$StationNo)
            {
                if (!empty($weather['StationNo']))
                    $selected_weather['StationNo']=$weather['StationNo'] ;
                if (!empty($weather['fcity']))
                    $selected_weather['fcity']=$weather['fcity'] ;
                if (!empty($weather['DateTime1']))
                    $selected_weather['DateTime1']=$weather['DateTime1'] ;
                else
                    $selected_weather['DateTime1']='نامشخص' ;
                if (!empty($weather['Tmp']))
                    $selected_weather['Tmp']=$weather['Tmp'] ;
                else
                    $selected_weather['Tmp']='نامشخص' ;
                if (!empty($weather['WindSpeed']))
                    $selected_weather['WindSpeed']=$weather['WindSpeed'] ;
                else
                    $selected_weather['WindSpeed']='نامشخص' ;
                if (!empty($weather['widir']))
                    $selected_weather['windir']=$weather['windir'] ;
                else
                    $selected_weather['windir']='نامشخص' ;
                if (!empty($weather['Curr_weather']))
                    $selected_weather['Curr_weather']=$weather['Curr_weather'] ;
            }
        }
        return $selected_weather ;    
    }
}
?>

Step2: Create the file (if not exist) "/app/controllers/app_controller.php" and copy following codes in to it:


<?php
class AppController extends Controller {
    var $helpers = array('Html', 'Form', 'Ajax', 'Javascript');
    var $components= array('IrWeather') ;
    
    function beforeRender()
    {
        if (!empty($this->data['weather']['fcities']))
        {
            $this->layout='Ajax' ;
            $selected_weather=$this->IrWeather->show_details($this->data['weather']['fcities']) ;
            echo 'تاریخ: '.$selected_weather['DateTime1'].'<br>'.'دما: '.$selected_weather['Tmp'].'<br>'.'سرعت Ø¨Ø§Ø¯:'.$selected_weather['WindSpeed'].'<br>'.'جهت Ø¨Ø§Ø¯:'.$selected_weather['windir'].'<br>'.'هوای ÙØ¹Ù„ÛŒ:'.$selected_weather['Curr_weather'] ;
        }
        $this->set('weathers',$this->IrWeather->get_weathers()) ;
    }
?>
Step3 : create an element "/app/views/elements/ir_weather.ctp" and copy below codes into it:


    <select id="fcities" name="data[weather][fcities]">
    <?php
        foreach ($weathers['Root']['Row'] as $weather)
        {
            if (!empty($weather['StationNo']) && !empty($weather['fcity']))
                echo '<option value="'.$weather['StationNo'].'">'.$weather['fcity'].'</option>' ;
        }
    ?>
    </select>
    <?php
        echo $ajax->observeField('fcities',array('url'=>'','update'=>'weather_details')) ;
    ?>
    <div id="weather_details"></div>

Final Step:
add this line to "/app/views/layouts/default.ctp" file in a position you want:

<?php echo $this->element('ir_weather'); ?>

you can use images for weather status or optimize the fetch operation with some little modifications.
