Recently I was working on project that has many objects for displaying on a map.
So there was need ta build an interface, for simple coordinate picking for database objects.
After some googling, I have found nice jQuery plugin for this purpose.
So I have made widget for Yii with this jQuery plugin.
Example of usage:
echo $form->textField($model, 'lat');
echo $form->textField($model,'long');
$this->widget('ext.coordinatepicker.CoordinatePicker', array(
'model' => $model,
'latitudeAttribute' => 'lat',
'longitudeAttribute' => 'long',
));
