Multiple polygons on google map with hover show, hide

Here you can find the multiple ploygons on the google map and we can show and hide the ploygons as per the title mouse over, i didt find much time to shorten this jquery code. Meantime i am not ok with the line 


idx=jQuery(this).attr('id');
for(var i=0,l=countries.length;i
if(idx==i){countries[i].setMap(map);}
else{countries[i].setMap(null);}
}


I cant able to directly assign my idx value like this countries[idx].setMap(map);, if i put like then it is showing as countriex[idx] is not a function, if anyone know the solution please let me know




Put your google map script URL
Put your Jquery ajax URL
Set your div tags with ID values

How to show the Active/ Inactive dropdown status in YII C detail View

Its simple to set the active, inactive in the C detail View dropdown list, just assign the status value as like the below format


 array(             
            'label'=>'Status',
            'type'=>'raw',
            'value'=>($model->status == 1) ? "Active" : "Inactive",
        ),

CActiveDataProvider Yii - Is simple and neat

CActiveDataProvider Yii - Is simple and neat, where we can enter our condition, pagination etc

I actually started coding with custom select query in YII, but while referred to "CActiveDataProvider" with conditions and pagination there is no need for to call the  sql query second time with condition or pagination

Here i will explain what i had previously and how the YII default CActiveDataProvider is working


My custom code in my controller function:
===========================================

public function actionList()

{
$criteria = new CDbCriteria();

$criteria->addCondition('user_id='.Yii::app()->user->id.'');
$count = Blog::model()->count($criteria);
$pages = new CPagination($count);

 
$pages->pageSize = 5;
$pages->applyLimit($criteria);
$models = Blog::model()->findAll($criteria);
$this->render('list', array('models' => $models, 'pages' => $pages));
}


While following the above code, i need to call this $model inside a foreach and need to show the values. 



YII default CActiveDataProvider in my controller function:
===========================================

public function actionList()
{
$criteria=new CDbCriteria;
$criteria->order='id DESC';  
$dataProvider=new CActiveDataProvider('Blog',array('criteria'=>$criteria,'pagination' => array('pageSize'=>Yii::app()->params['PaginationPerPage']),));
$this->render('list',array('dataProvider'=>$dataProvider,));
}

This is what Yii gave in default, its simple. And while following this code we can simply use the default view format from YII like below 


$this->widget('zii.widgets.CListView', array('dataProvider'=>$dataProvider,'itemView'=>'_view',)); 
?>

How to set the country, state relationship in Yii

My Country table:
================
id
name


My state table:
===============
id
country_id
name



Here i need to refer the country from state using the country_id relationship

So first i need to generate a Relationship in my State Model like below


public function relations()
{

return array(
'country'=>array(self::BELONGS_TO, 'Country', 'country_id'),
);

}

Country here is the country model
country_id is the reference key in state table to refer the country table


Ok so in CGrid view use the below format

'country.name',


===========================================================================

And if we need filtering for countries in state admin?

Just use the compare setup like below

public function search()
{
// @todo Please modify the following code to remove attributes that should not be searched.

$criteria=new CDbCriteria;

$criteria->compare('id',$this->id);
$criteria->compare('name',$this->name);
$criteria->with = array('country');
$criteria->compare('country.id',$this->country_id, true);

return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}


And in your Cgridview area have it like below


array(
'name'=>'country_id',
'header'=>'Country',
'value'=>'$data->country->name',
'filter'=>CHtml::listData(Country::model()->findall(),'id','name' ),
),

How to set the active and inactive status for 1,0 values in YII CGridView

In Yii normal CGridView will have the below structure


'columns'=>array(
'id',
'title',
'sstatus',

So to set the 0 as Inactive and 1 as Active 

we need to edit the 'status' as

array(
'header'=>'status', //for to set the title for the table column, we can remove this if we need to show the default value
'name'=>'sstatus' // where sstatus is my database column name
'value'=>'($data->sstatus==1)? "Active" : "Inactive"'
),


Once set we can see 0 as inactive and 1 as active. 


But how about filtering? 
The filtering in Yii will work when we input 1 and not as active, so just replace this filter area with dropdown list in the same area where we updated our above code, just add filter array like below



array(
'header'=>'status', //for to set the title for the table column, we can remove this if we need to show the default value
'name'=>'sstatus' // where sstatus is my database column name
'value'=>'($data->sstatus==1)? "Active" : "Inactive"',

'filter'=>CHtml::dropDownList('Slider[sstatus]', 'sstatus',  
                array(
                    ''=>'All',
                    '1'=>'Active',
                    '0'=>'Inactive',
                )
            ),
        ),

),



in the above Slider is my model name and sstatus is my database table column... thats it.......


But i faced some problems like auto select and select all is not working, so we can set the filter directly like the below code


  array(
           'name' => 'sstatus',
           'filter' => array(0 => 'In Active', 1 => 'Active'),
'value' => '($data->sstatus == 1) ? "Active" : "Inactive"',
       ),

PHP Translator, replacement for google translator api?.

I struggled to get the language translator for my php project and found Google API is not WORKING FOR ME, I dont know it works for others. While surfed i got google closed its Free Translator API, and microsoft is providing its API with limited character free subscription.

The code providing by them comes in SOAP, HTTP and Javascript and yes it supported my PHP. Even they are providing exact PHP class files that helped me a lot. You can register your Keys with them, use this link for to Sign up for the Microsoft Translator API "https://datamarket.azure.com/dataset/1899a118-d202-492c-aa16-ba21c33c06cb". They have listed all the subscription plans ranges from free to $6000/ month.

I think this link will also helpful http://www.microsofttranslator.com/dev/. After creating your Keys register with Datamarket and your translator will work good. I have used HTTP >> Translate Method "http://msdn.microsoft.com/en-us/library/ff512421.aspx" and there you can see the PHP class files, and it is very handy......


Happy coding
