I've got a problem with new products block for homepage, it's a free module provided by prestasop legend: VEKIA.

i see there this error:

 

 

[color=rgb(104,115,127);font-family:Arial, Helvetica, sans-serif;font-size:13px;]Fatal error: Call to undefined method homenewproducts::getCacheId()[/color]

how to fix it?

hello

 

it doesnt want to work because of caching in prestashop 1.5.3.1 - caching just doesnt work for modules in that version of prestashop.

My module uses caching - this is why prestashop spawns error.

 

solution is easy. open module php file (main module file) and replace whole code with this:

<?phpif (!defined('_PS_VERSION_'))	exit;class homenewproducts extends Module{	private $_html = '';	private $_postErrors = array();	function __construct()	{		$this->name = 'homenewproducts';		$this->tab = 'front_office_features';		$this->version = '1.1';		$this->author = 'MyPresta.eu';		parent::__construct();		$this->displayName = $this->l('New products on the homepage');		$this->description = $this->l('Displays new products in the middle of your homepage.');	}	function install(){		//$this->_clearCache('homenewproducts.tpl');		Configuration::updateValue('HNP_NBR', 8);		if (!parent::install()			|| !$this->registerHook('displayHome')			|| !$this->registerHook('header')			|| !$this->registerHook('addproduct')			|| !$this->registerHook('updateproduct')			|| !$this->registerHook('deleteproduct')		)			return false;		return true;	}		public function uninstall(){		//$this->_clearCache('homenewproducts.tpl');		return parent::uninstall();	}	public function getContent(){		$output = '<h2>'.$this->displayName.'</h2>';		if (Tools::isSubmit('submitHomeFeatured'))		{			$nbr = (int)Tools::getValue('nbr');			if (!$nbr OR $nbr <= 0 OR !Validate::isInt($nbr))				$errors[] = $this->l('An invalid number of products has been specified.');			else				Configuration::updateValue('HNP_NBR', (int)($nbr));			if (isset($errors) AND sizeof($errors))				$output .= $this->displayError(implode('<br />', $errors));			else				$output .= $this->displayConfirmation($this->l('Your settings have been updated.'));		}		return $output.$this->displayForm();	}	public function displayForm(){		$output = '<iframe src="http://mypresta.eu/content/uploads/2012/09/htmlbox_advertise.html" width="100%" height="130" border="0" style="border:none;"></iframe>		<form action="'.Tools::safeOutput($_SERVER['REQUEST_URI']).'" method="post">			<fieldset><legend><img src="'.$this->_path.'logo.gif" alt="" title="" />'.$this->l('Settings').'</legend>				<label>'.$this->l('Define the number of products to be displayed.').'</label>				<div class="margin-form">					<input type="text" size="5" name="nbr" value="'.Tools::safeOutput(Tools::getValue('nbr', (int)(Configuration::get('HNP_NBR')))).'" />					<p class="clear">'.$this->l('Define the number of products that you would like to display on homepage (default: 8).').'</p>				</div>				<center><input type="submit" name="submitHomeFeatured" value="'.$this->l('Save').'" class="button" /></center>			</fieldset>		</form>'.$this->l('like us on Facebook').'</br><iframe src="//www.facebook.com/plugins/like.php?href=http%3A%2F%2Ffacebook.com%2Fmypresta&amp;send=false&amp;layout=button_count&amp;width=120&amp;show_faces=true&amp;font=verdana&amp;colorscheme=light&amp;action=like&amp;height=21&amp;appId=276212249177933" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:120px; height:21px; margin-top:10px;" allowtransparency="true"></iframe>        '.'<div style="float:right; text-align:right; display:inline-block; margin-top:10px; font-size:10px;">        '.$this->l('Proudly developed by').' <a href="http://mypresta.eu" style="font-weight:bold; color:#B73737">MyPresta<font style="color:black;">.eu</font>.</a>        ';		return $output;	}	public function hookDisplayHeader($params){		$this->hookHeader($params);	}	public function hookHeader($params){		$this->context->controller->addCSS(($this->_path).'homenewproducts.css', 'all');	}	public function hookDisplayHome($params){		//if (!$this->isCached('homenewproducts.tpl', $this->getCacheId('homenewproducts'))){			$nb = (int)Configuration::get('HNP_NBR');              $productClass = new Product();             $products = $productClass -> getNewProducts((int)Context::getContext()->language->id,0,($nb ? $nb : 8));			$this->smarty->assign(array(				'products' => $products,				'add_prod_display' => Configuration::get('PS_ATTRIBUTE_CATEGORY_DISPLAY'),				'homeSize' => Image::getSize(ImageType::getFormatedName('home')),			));		//}		return $this->display(__FILE__, 'homenewproducts.tpl');	}	public function hookAddProduct($params){		//$this->_clearCache('homenewproducts.tpl');	}	public function hookUpdateProduct($params){		//$this->_clearCache('homenewproducts.tpl');	}	public function hookDeleteProduct($params){		//$this->_clearCache('homenewproducts.tpl');	}}
