    Opencart首頁最新產(chǎn)品(LatestProducts)隨機(jī)顯示方法

    Opencart首頁LatestProducts產(chǎn)品是不可控的，如果一直不上傳新產(chǎn)品，LatestProducts顯示固定不變，不像zen-cart每次刷新都有變化。我?guī)退鼊右幌滦∈中g(shù)。

    文件位置：catalogmodelcatalogproduct.php.

    方法一

    把getLatestProducts修改成以下代碼：

    publicfunctiongetLatestProducts($limit){

    $query=$this->db->query("SELECT*,pd.nameASname,p.image,m.nameASmanufacturer,ss.nameASstock,(SELECTAVG(r.rating)FROM".DB_PREFIX."reviewrWHEREp.product_id=r.product_idGROUPBYr.product_id)ASratingFROM".DB_PREFIX."productpLEFTJOIN".DB_PREFIX."product_descriptionpdON(p.product_id=pd.product_id)LEFTJOIN".DB_PREFIX."product_to_storep2sON(p.product_id=p2s.product_id)LEFTJOIN".DB_PREFIX."manufacturermON(p.manufacturer_id=m.manufacturer_id)LEFTJOIN".DB_PREFIX."stock_statusssON(p.stock_status_id=ss.stock_status_id)WHEREp.status='1'ANDp.date_available<=NOW()ANDpd.language_id='".(int)$this->config->get('config_language_id')."'ANDp2s.store_id='".(int)$this->config->get('config_store_id')."'ANDss.language_id='".(int)$this->config->get('config_language_id')."'ORDERBYrand()DESCLIMIT".(int)$limit);

    $product_data=$query->rows;

    return$product_data;

    }

    方法二

    把getLatestProducts修改成以下代碼：

    publicfunctiongetLatestProducts($limit){

    $product_data=$this->cache->get('product.latest.'.$this->config->get('config_language_id').'.'.(int)$this->config->get('config_store_id').'.'.$limit);

    if(!$product_data){

    $query=$this->db->query("SELECT*,pd.nameASname,p.image,m.nameASmanufacturer,ss.nameASstock,(SELECTAVG(r.rating)FROM".DB_PREFIX."reviewrWHEREp.product_id=r.product_idGROUPBYr.product_id)ASratingFROM".DB_PREFIX."productpLEFTJOIN".DB_PREFIX."product_descriptionpdON(p.product_id=pd.product_id)LEFTJOIN".DB_PREFIX."product_to_storep2sON(p.product_id=p2s.product_id)LEFTJOIN".DB_PREFIX."manufacturermON(p.manufacturer_id=m.manufacturer_id)LEFTJOIN".DB_PREFIX."stock_statusssON(p.stock_status_id=ss.stock_status_id)WHEREp.status='1'ANDp.date_available<=NOW()ANDpd.language_id='".(int)$this->config->get('config_language_id')."'ANDp2s.store_id='".(int)$this->config->get('config_store_id')."'ANDss.language_id='".(int)$this->config->get('config_language_id')."'ORDERBYrand()DESCLIMIT".(int)$limit);

    $product_data=$query->rows;

    $this->cache->set('product.latest.'.$this->config->get('config_language_id').'.'.(int)$this->config->get('config_store_id').'.'.$limit,$product_data);

    }

    return$product_data;

    }

    去前臺刷新一下，看一下效果
