php - Wrong product URLs magento -

i've been working on custom sells related products script, displaying 4 random products.

problem is:

normal product url is:

/shop/$productname

this generating url like: /$productname/

or url like: /catalog/product/view/id/$productid/4/s/$productname/category/$categoryid/

i want have urls same so: /shop/$productname

<div class="upsell"> <h2>you might interested in</h2>     <?php // list mode ?>     <?php $_iterator = 0; ?>     <?php // grid mode ?>     <table class="products-grid upsell" id="upsell-product-table">                     <tbody>                     <tr>     <?php $_collectionsize = $_productcollection->count() ?>     <?php $_columncount = $this->getcolumncount(); $_columncount=4; ?>     <?php $i=0; foreach ($_productcollection $_product): ?>         <?php if ($i++%$_columncount==0): ?>         <?php endif ?>             <td>             <?php // initiate product model $product = mage::getmodel('catalog/product');  // load specific product tier price want update $product ->load($_product->getid()); ?>                 <a href="<?php echo $product->getproducturl() ?>" title="<?php echo $this->striptags($this->getimagelabel($product, 'small_image'), null, true) ?>" class="product-image"><img src="<?php echo $this->helper('catalog/image')->init($product, 'small_image')->resize(170); ?>" width="125" height="125" alt="<?php echo $this->striptags($this->getimagelabel($_product, 'small_image'), null, true) ?>" /></a>                  <h3 class="product-name"><a href="<?php echo $product->getproducturl() ?>" title="<?php echo $this->striptags($product->getname(), null, true) ?>"><?php echo $_helper->productattribute($product, $product->getname(), 'name') ?></a></h3>                 <?php echo $this->getpricehtml($product, true) ?>              </td>         <?php endforeach; ?>         </tr>         </tbody>         </table> </div> 

try

$this->geturl('shop').$product->geturlpath() 

instead of

$product->getproducturl() 

for both image , product title.
