Set or Get request variables in Magento
Get Request params like this:
Get every post variable in array like this:
1
2
3
4
5
| $postData = Mage::app()->getRequest()->getPost();// You can access individual variables like...if (isset($postData['product_id'])) { echo $postData['product_id'];} |
$this->getRequest()->getParams() to get all Parameters.$this->getRequest()->getParam(KEY) to get any specifically.
//
$_POST['deviceid']$deviceid = $this->getRequest()->getPost('deviceid');
Here, a URL like
http://www.example.com/artists/index/view/id/64 can be used to view the profile for any artist, the artist_id is simply substituted into your query string after the /id/ section. Now is the clever part, to access this value in your controller for viewAction(), you simply use the following function:$artistid = (int)$this->getRequest()->getParam('id');
$id = (int)$this->getRequest()->getParam('id');
$_GET, $_POST & $_REQUEST Variables in Magento
Accessing Get Variables – $_GET
// This...
$productId = $_GET['product_id'];
$productId = $_GET['product_id'];
// ...is the same as ...
$productId = Mage::app()->getRequest()->getParam(‘product_id’);
$productId = Mage::app()->getRequest()->getParam(‘product_id’);
// The second parameter to getParam allows you to set a default value
// The default value is returned if the GET value you’re looking for isn’t set
$productId = Mage::app()->getRequest()->getParam(‘product_id’, 44);
// The default value is returned if the GET value you’re looking for isn’t set
$productId = Mage::app()->getRequest()->getParam(‘product_id’, 44);
?>
Accessing Post Variables – $_POST

$postData = $_POST;
$postData = $_POST;

// You can access individual variables like…
if (isset($postData['product_id'])) {
