title: Get latest or new products on home page in magento with layout update
body: <p>I create new theme in Magento and want to show latest or new products on home page with pagination and number of show product. I copied catalog/product/list.phtml from it's cored file to my template so that i can customize it.</p>
  
  <p>Below is code in layout update in homepage:</p>
  
  <pre><code>&lt;reference name="content"&gt;
     &lt;block type="catalog/product_list" name="product_list" template="catalog/product/list.phtml"&gt;
        &lt;action method="setCategoryId"&gt;&lt;category_id&gt;3&lt;/category_id&gt;&lt;/action&gt;
        &lt;block type="catalog/product_list_toolbar" name="product_list_toolbar" template="catalog/product/list/toolbar.phtml"&gt;
        &lt;block type="page/html_pager" name="product_list_toolbar_pager"/&gt;&lt;/block&gt;
        &lt;action method="setToolbarBlockName"&gt;&lt;name&gt;product_list_toolbar&lt;/name&gt;&lt;/action&gt;
     &lt;/block&gt;
  &lt;/reference&gt;
  </code></pre>
  
  <p>It work well with is code, but only with category I set in layout update.</p>
  
  <pre><code>&lt;action method="setCategoryId"&gt;&lt;category_id&gt;3&lt;/category_id&gt;&lt;/action&gt;
  </code></pre>
  
  <p>What I want is get all latest or new product from all category.</p>
  
  <p>Question: how can I get latest or new products with layout update with all category or multiple category?</p>
