[SOLVED] Modify blocknewproducts to show products from one category

[lewisdonovan]

Hi, I'm trying to show a block on the homepage that lists all products from a single category, along with image and description (truncated to 60 chars).

I have tried to adapt the blocknewproducts module but don't know where to start.

Any help would be greatly appreciated.

Change line 65 of modules/blocknewproducts/blocknewproducts.php from:

$newProducts = Product::getNewProducts(intval($params['cookie']->id_lang), 0, intval(Configuration::get('NEW_PRODUCTS_NBR')));

to:

//$newProducts = Product::getNewProducts(intval($params['cookie']->id_lang), 0, intval(Configuration::get('NEW_PRODUCTS_NBR')));
$category = new Category(2, intval($params['cookie']->id_lang));
$newProducts = $category->getProducts(intval($params['cookie']->id_lang), 1, 10);

Change 2 to the ID of the category you want to get the products from and 10 to how many products you want to get. Note that the more products you get, the slower your website will become.

Hmmm, it's still not working. Below is the code from my .php and .tpl files for this module, including the fix you mentioned.

blocknewproducts.php:

<?php
class BlockNewProducts extends Module
{
   private $_html = '';
   private $_postErrors = array();
   function __construct()
   {
       $this->name = 'blocknewproducts';
       $this->tab = 'Blocks';
       $this->version = 0.9;
       parent::__construct();
       /* The parent construct is required for translations */
       $this->page = basename(__FILE__, '.php');
       $this->displayName = $this->l('New products block');
       $this->description = $this->l('Displays a block featuring newly added products');
   }
   function install()
   {
       if (parent::install() == false 
               OR $this->registerHook('home') == false
               OR Configuration::updateValue('NEW_PRODUCTS_NBR', 5) == false)
           return false;
       return true;
   }
   public function getContent()
   {
       $output = ''.$this->displayName.'';
       if (Tools::isSubmit('submitBlockNewProducts'))
       {
           if (!$productNbr = Tools::getValue('productNbr') OR empty($productNbr))
               $output .= ''.$this->l('You should fill the "products displayed" field').'';
           elseif (intval($productNbr) == 0)
               $output .= ''.$this->l('Invalid number.').'';
           else
           {
               Configuration::updateValue('NEW_PRODUCTS_NBR', intval($productNbr));
               $output .= 'l('Confirmation').'" />'.$this->l('Settings updated').'';
           }
       }
       return $output.$this->displayForm();
   }
   public function displayForm()
   {
    $output = '
       <form action="'.$_SERVER['REQUEST_URI'].'" method="post">
_path.'logo.gif" alt="" title="" />'.$this->l('Settings').'
'.$this->l('Products displayed').'

                   <input type="text" name="productNbr" value="'.Configuration::get('NEW_PRODUCTS_NBR').'" />

'.$this->l('Set the number of products to be displayed in this block').'

<input type="submit" name="submitBlockNewProducts" value="'.$this->l('Save').'" class="button" />            

       </form>';
       return $output;
   }
   function hookhome($params)
   {
       global $smarty;
       $currency = new Currency(intval($params['cookie']->id_currency));
       //$newProducts = Product::getNewProducts(intval($params['cookie']->id_lang), 0, intval(Configuration::get('NEW_PRODUCTS_NBR')));
$category = new Category(73, intval($params['cookie']->id_lang));
$newProducts = $category->getProducts(intval($params['cookie']->id_lang), 1, 10);
       $new_products = array();
       if ($newProducts)
           foreach ($newProducts AS $newProduct)
               $new_products[] = $newProduct;
       $smarty->assign('new_products', $new_products);
       return $this->display(__FILE__, 'blocknewproducts.tpl');
   }
   function hookLeftColumn($params)
   {
       return $this->hookhome($params);
   }
}
?>

blocknewproducts.tpl:

<!-- MODULE Block new products -->


{l s='New products' mod='blocknewproducts'}
{l s='See all' mod='blocknewproducts'}

   {if $new_products}
           {foreach from=$new_products item=product name=myLoop}
       {/foreach}






{$new_products.0.name|escape:htmlall:'UTF-8'|truncate:30}

           {if $product.description_short}

           {/if}

           {if $product.description_short}

        {else}

{l s='No new product at this time' mod='blocknewproducts'}
   {/if}

I forgot the

 tag in the second block above.  I've updated my post.  Please try again.

[lewisdonovan]

Okay, it's now listing products from the category I want but it's only listing 4 products, not 10.
Is this something to do with the foreach statement in blocknewproducts.tpl coming BEFORE the UL and LI tags?

Thanks

[rocky]

Yes, it seems your code is hardcoded to display only 4 products. Try the following code instead:

<!-- MODULE Block new products -->


{l s='New products' mod='blocknewproducts'}
{l s='See all' mod='blocknewproducts'}

   {if $new_products}

           {foreach from=$new_products item=new_product name=myLoop}

            <a href="{$new_product.link}">
             <img src="{$img_prod_dir}{$new_product.id_image}-small.jpg" height="40" width="40" alt="{$new_product.legend|escape:htmlall:'UTF-8'}">


             <a href="{$new_product.link}" title="{$new_product.name|escape:htmlall:'UTF-8'}">{$new_product.name|escape:htmlall:'UTF-8'|truncate:30}

           {if $new_product.description_short}

             <a href="{$new_product.link}">{$new_product.description_short|strip_tags:htmlall:'UTF-8'|truncate:60}
             <a class="linkview" href="{$new_product.link}" title="{$new_product.name|escape:htmlall:'UTF-8'}">              

           {/if}

       {/foreach}

        {else}

{l s='No new product at this time' mod='blocknewproducts'}
   {/if}

<!-- /MODULE Block new products -->

//$newProducts = Product::getNewProducts(intval($params['cookie']->id_lang), 0, intval(Configuration::get('NEW_PRODUCTS_NBR')));
$category = new Category(29, intval($params['cookie']->id_lang));
$newProducts = $category->getProducts(intval($params['cookie']->id_lang), 1, 4);

I forgot to reply to this thread after your last post, rocky.
Cheers for all of that, it's running fine now. You're a star.

Can this be modified to show only the products that have positive stock? and the number of products still be acording to the number of prod set up in BO.
