Hi,

hope this helps you :




$modelPrecedent = Produit::model()->findBySql("Select * from Produit where ProduitID < ".$model->ProduitID." Order By ProduitID desc");

$modelSuivant = Produit::model()->findBySql("Select * from Produit where ProduitID > ".$model->ProduitID." Order By ProduitID");

if($modelPrecedent!=null)

	echo '<a href="index.php?r=produit/view&id='.$modelPrecedent->ProduitID.'><img src="images/previous.jpg" /></a>';

if($modelSuivant!=null)

	echo '<a href="index.php?r=produit/view&id='.$modelSuivant->ProduitID.'><img src="images/next.jpg" /></a>';

And how to handle multiple search params ?

Should send them with query string when user will go to detail page?

I’m new to all this but in one of the demos apps, they show a private var that is used to pass info to other functions. Could that work?

Off the top of my head…

In Model:




class Model1 .....

{

   ...

   private _prevId = null;

   private _nextId = null;

   ...


   public function afterFind()

   {

    //find/calculate/set $this->_prevId;

    //find/calculate/set $this->_nextId;

   }


   public function getPrevId() {

      return $this->prevId;

   }

   public function getNextId() {

      return $this->nextId;

   }

}

Check the code generated in the ViewDetal link and modify for the Prev/Net links in the _view file using $model(or $data)->prevId/nextId in the array(‘id’=>#) section.

I would think that would also keep the search params intact will "surfing."

If this doesn’t work, it might point you in a direction that does. Just tring to do my part :)
