I have modified the _prepareLayout() function in Mage_Catalog_Block_Category_View class to have a customized canonical url. After modifying the URL, the canonical code does not display in the html source code anymore.
Here are my codes:
protected function _prepareLayout() {
Mage_Core_Block_Template::_prepareLayout();
$this->getLayout()->createBlock('catalog/breadcrumbs');
if ($headBlock = $this->getLayout()->getBlock('head')) {
$category = $this->getCurrentCategory();
if ($title = $category->getMetaTitle()) {
$headBlock->setTitle($title);
}
if ($description = $category->getMetaDescription()) {
$headBlock->setDescription($description);
}
if ($keywords = $category->getMetaKeywords()) {
$headBlock->setKeywords($keywords);
}
if ($this->helper('catalog/category')->canUseCanonicalTag()) {
//$headBlock->addLinkRel('canonical', $category->getUrl());
if ($category->getCategoryUrlAlias()) {
$url = Mage::getBaseUrl() . $category->getCategoryUrlAlias();
} else {
$key = $this->helper('my_package/category')->getIsTitleCategoryKey($category);
$url = $category->getUrl();
$url = $this->_removeKeyFromUrl($url, $key);
}
$headBlock->addLinkRel('canonical', $url);
}
/*
want to show rss feed in the url
*/
if ($this->IsRssCatalogEnable() && $this->IsTopCategory()) {
$title = $this->helper('rss')->__('%s RSS Feed', $this->getCurrentCategory()->getName());
$headBlock->addItem('rss', $this->getRssLink(), 'title="' . $title . '"');
}
}
return $this;
}
I have verified that the $url variable always have the customized url value that I want. I'm wondering if there is any validation function that's preventing me to have a customized canonical URL?
Any help will be greatly appreciated. Thanks!

Can anybody help as I am trying to use the codeigniter's upload library from the helpers folder but I keep getting the same error that I am not selecting an image to upload? Has any body tried this before?
class FileUpload extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->helper(array('form', 'file_uploading'));
$this->load->library('form_validation', 'upload');
}
public function index() {
$data = array('title' => 'File Upload');
$this->load->view('fileupload', $data);
}
public function doUpload() {
$submit = $this->input->post('submit');
if ( ! isset($submit)) {
echo "Form not submitted correctly";
} else { // Call the helper
if (isset($_FILES['image']['name'])) {
$result = doUpload($_FILES['image']);
if ($result) {
var_dump($result);
} else {
var_dump($result);
}
}
}
}
}
The Helper Function
<?php
function doUpload($param) {
$CI = &get_instance();
$CI->load->library('upload');
$config['upload_path'] = 'uploads/';
$config['allowed_types'] = 'gif|png|jpg|jpeg|png';
$config['file_name'] = date('YmdHms' . '_' . rand(1, 999999));
$CI->upload->initialize($config);
if ($CI->upload->do_upload($param['name'])) {
$uploaded = $CI->upload->data();
return $uploaded;
} else {
$uploaded = array('error' => $CI->upload->display_errors());
return $uploaded;
}
}
There are some minor mistakes in your code, please fix it as below,
$result = doUpload($_FILES['image']);
here you should pass the form field name, as per your code image is the name of file input.
so your code should be like
$result = doUpload('image');
then, inside the function doUpload you should update the code
from
$CI->upload->do_upload($param['name'])
to
$CI->upload->do_upload($param)
because Name of the form field should be pass to the do_upload function to make successful file upload.
NOTE
Make sure you added the enctype="multipart/form-data" in the form
element
I'm trying to understand Joomla language and I have this situation:
In a models/calcoloonline.php I have this function
public function estraivariabili()
{
$db = JFactory::getDBO();
// Put the result into a variable first, then return it.
$value = $db->setQuery("SELECT * FROM #__calcolo_imposte")->loadObjectList();
if ($value != NULL)
{
return $value;
}
else
{
return JFactory::getApplication()->enqueueMessage(JText::_('COM_CALCOLO_IMPOSTE_IMPORTI_NON_DEFINITI'), 'type');
}
}
This works perfectly but I'd like that after check if the return is NULL I want to hide display default.php and show only the message on JText.
How can I do this?
For your purpose, you just return the $value from the model function and call the function at view.html.php's display() function.
At default.php file check the availability of the $value and show your contents.
For example, you store the data at view.php.html. It looks like
public function display($tpl = null)
{
$model = $this->getModel();
$this->value = $model->estraivariabili();
return parent::display($tpl);
}
And your default.php file would be
<?php if (!empty($this->value)) { ?>
<h1>The value is not empty.</h1>
<?php } else {
// value not found :(
JFactory::getApplication()->enqueueMessage(JText::_('NOT_FOUND_MESSAGE'), 'warning');
} ?>
I have build my own component in joomla and client wants now a friendly urls f.e
website.com/someplace/{product-id}-{product-name}. So i Build my own router like this.
function componentBuildRoute(&$query)
{
$segments = [];
if (isset($query['view'])) {
$segments[] = "szkolenie";
unset($query['view']);
}
if (isset($query['product_id'])) {
$productName = JFilterOutput::stringURLSafe(strtolower(getProductName($query['product_id'])));
$newName = $query['product_id'] . '-' . $productName;
$segments[] = $newName;
unset($query['product_id']);
}
return $segments;
}
and parse route function
function componentParseRoute($segments)
{
$app = JFactory::getApplication();
$menu = $app->getMenu();
$item =& $menu->getActive();
$count = count($segments);
switch ($item->query['view']) {
case 'catalogue' : {
$view = 'training';
$id = $segments[1];
}
break;
}
$data = [
'view' => $view,
'product_id' => $id
];
return $data;
}
While on the end of buildroute function segments are ok I have exactly what I want that on the beginning of parse route I have something like
website.com/szkolenie/1-krakow <-- I dont know wtf is this krakow( I know it is city i Poland) but still where is it get from ? The getProductName function implementation is
function getProductName($productId)
{
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select('#__component_training.id as id, #__component_product' . name)
->from($db->quoteName('#__component_training'))
->where('#__s4edu_product.product_id = ' . $productId)
->leftJoin('#__component_product ON
#__component_training.product_id=#__component_product.product_id');
$training = $db->loadObject();
return trim($training->name);
}
So taking all this into consideration I think that something is happening between the buildRoute and parseRoute, something what filters the $segment[1] variable, but how to disable that and why is it happening ?
P.S
Please do not send me to https://docs.joomla.org/Joomla_Routes_%26_SEF
I already know all the tutorials on joomla website which contains anything with sef.
P.S.S
It is built on joomla 3.7.0
You do not have a product named "krakow" ?
If not you can try to remove the $productName from the build function, just to check if this "krakow" is added automaticaly or it's from the getProductName() function.
Also i noticed that you have an error i guess in the function getProductName()
->where('#__s4edu_product.product_id = ' . $productId)
It's should be
->where('#__component_product.product_id = ' . $productId)
I am using php function_exists() function exist on my Welcome controller. But for some reason it keeps on throwing my show_error even though my slideshow function exists.
With in my foreach loop I get module function name from database which in the foreach loop is called $function = $module['code'];
Question is: How am I able to make sure function_exists checks
function exists correctly?
<?php
class Welcome extends CI_Controller {
public function index() {
$data['content_top'] = $this->content_top();
$this->load->view('home', $data);
}
public function content_top() {
$data['modules'] = array();
$modules = $this->get_module();
foreach ($modules as $module) {
$function = $module['code'];
if (function_exists($function)) {
$setting_info = array('test' => 'testing');
if ($setting_info) {
$data['modules'][] = $this->$function($setting_info);
}
} else {
show_error('This ' . $function . ' does not exist on ' . __CLASS__ . ' controller!');
}
}
return $this->load->view('content_top', $data, TRUE);
}
public function banner() {
}
public function slideshow($setting) {
$data['test'] = $setting['test'];
$this->load->view('module/slideshow', $data);
}
public function get_module() {
$query = $this->db->get('modules');
return $query->result_array();
}
}
function_exists() works on functions, but not class methods - these are different things. What you want is method_exists():
method_exists($this, $function);
I want to remove some URL parameter (like utm_source, but whatever), put it in session and redirect to same page with URL clean of this specific param
I've done in controller_front_init_before like this:
$frontController = $observer->getEvent()->getFront();
$params = $frontController->getRequest()->getParams();
$myParams = array("b");
foreach($myParams as $myParam) {
if (isset($params[$myParam])) {
$customerSession->setData(
$myParam, $params[$myParam]
);
unset($params[$myParam]);
}
}
$frontController->getRequest()->setParams($params); // <- I don't know what to do with that
Now what is the best method to redirect to the same page in request ?
For example redirect http://example.com?a=1&b=2&c=3 to http://example.com?a=1&c=3
Thanks!
$frontController = $observer->getEvent()->getFront();
$params = $frontController->getRequest()->getParams();
$shouldRedirect = false
foreach($params as $key => $value) {
if ($key !== 'b') {
$customerSession->setData($key, $value);
}
else{
unset($params[$key]);
$shouldRedirect = true;
}
}
if($shouldRedirect){
//$url = get url and redirect
//see http://magento.stackexchange.com/questions/5000/add-query-parameters-to-an-existing-url-string
Mage::app()->getResponse()->setRedirect($url);
}
