Answer 1

You can use addCategoryFilter to filter a category.

$searchstring='comp';

$category = Mage::getModel('catalog/category')->load(141);

$product_collection = Mage::getResourceModel('catalog/product_collection')
->addAttributeToSelect('*')
->addCategoryFilter($category)
->addAttributeToFilter('name', array('like' => '%'.$searchstring.'%'));

foreach ($product_collection as $product) {
  echo  $product->getName().'<br>';
}

I'm don't have knowlegde about magento, but does this code work in PHP? Maybe it's not a syntax fault, but have you already tried something like this:

$product_collection = Mage::getResourceModel('catalog/product_collection');
$product_collection->addAttributeToSelect('*');
$product_collection->addAttributeToFilter('category_id', array('in' => array('finset' => '141'))); 
$product_collection->addAttributeToFilter('name', array('like' => '%'.$searchstring.'%'));
$product_collection->load();

Answer 3

may be this code bellow can help you :

$product_collection = Mage::getModel('catalog/product')
        ->getCollection()
        ->joinField('category_id', 'catalog/category_product', 'category_id', 'product_id = entity_id', null, 'left')
        ->addAttributeToSelect('*')
        ->addAttributeToFilter('category_id', array(
              array('finset' => $id1),
              array('finset' => $id2))
          )
        ->addAttributeToFilter('name', array('like' => '%'.$searchstring.'%'));

Searching product by category

In "advanced search" feature, searching product by category is not the default setting.  But we can do this by modifying the foloowing files:

app/code/core/Mage/CatalogSearch/Block/Advanced/Form.php
app/code/core/Mage/CatalogSearch/Model/Advanced.php
app/design/yourdesign/yourdesign/template/catalogsearch/advanced/form.phtml


At the bottom of app/code/core/Mage/CatalogSearch/Block/Advanced/Form.php we can add following codes:

public function getStoreCategories()
    {
        $helper = Mage::helper('catalog/category');
        return $helper->getStoreCategories();
    }


In app/code/core/Mage/CatalogSearch/Model/Advanced.php, replace the getSearchCriterias() by following functions:



 public function getSearchCriterias()

     {
     $search = $this->_searchCriterias;
              /* display category filtering criteria */
         if(isset($_GET['category']) && is_numeric($_GET['category'])) {
         $category = Mage::getModel('catalog/category')->load($_GET['category']);
         $search[] = array('name'=>'Category','value'=>$category->getName());
      }
      return $search;
     }


Replace the getProductCollection() by following function:

 public function getProductCollection(){
    if (is_null($this->_productCollection)) {
        $this->_productCollection = Mage::getResourceModel('catalogsearch/advanced_collection')
        ->addAttributeToSelect(Mage::getSingleton('catalog/config')->getProductAttributes())
        ->addMinimalPrice()
        ->addStoreFilter();
        Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($this->_productCollection);
        Mage::getSingleton('catalog/product_visibility')->addVisibleInSearchFilterToCollection($this->_productCollection);
        /* include category filtering */
        if(isset($_GET['category']) && is_numeric($_GET['category'])) $this->_productCollection->addCategoryFilter(Mage::getModel('catalog/category')->load($_GET['category']),true);
        }
        return $this->_productCollection;
} 



In page app/design/yourdesign/yourdesign/template/catalogsearch/advanced/form.phtml, find the codes as following:


   <input name="<?php echo $_code ?>" id="<?php echo $_code ?>" value="<?php echo $this->htmlEscape($this->getAttributeValue($_attribute)) ?>" title="<?php echo $this->htmlEscape($this->getAttributeLabel($_attribute)) ?>"  class="input-text <?php echo $this->getAttributeValidationClass($_attribute) ?>" type="text" />
            <?php endswitch; ?>
        </li>
        <?php endforeach; ?>



at the bottom of this piece of codes, add following codes:



<li>
<label for="category_search_field">Search by Category:</label>
<select name="category" id="category_search_field">
<option value="">-- Any Category --</option>
<?php foreach ($this->getStoreCategories() as $_category): ?>
<?php if($_category->hasChildren()): ?>
<option class="parent-cat" value="<?php echo $_category->getId(); ?>"><?php echo $_category->getName();?></option>
<?php foreach ($_category->getChildren() as $subcategory):
if($subcategory->getIsActive()) : ?>
<option value="<?php echo $subcategory->getId(); ?>"<?php echo ($this->getRequest()->getQuery('category') == $subcategory->getId() ? ' selected="selected"': "") ?>><?php echo $subcategory->getName(); ?></option>
<?php endif; endforeach; ?>
<?php elseif($_category->getIsActive()): ?>
<option value="<?php echo $_category->getId(); ?>"><?php echo $_category->getName();?></option>
<?php endif; ?>
<?php endforeach ?>
</select>
</li>

Same as above you can add change for product name filter also...
