Magento – Get Basket Total And Quantity

$items = Mage::getSingleton('checkout/session')->getQuote()->getAllItems();

 foreach($items as $item) {

    echo 'ID: '.$item->getProductId().'';

    echo 'Name: '.$item->getName().'';

    echo 'Sku: '.$item->getSku().'';

    echo 'Quantity: '.$item->getQty().'';

    echo 'Price: '.$item->getPrice().'';

    echo "";

}

$totalItems = Mage::getModel('checkout/cart')->getQuote()->getItemsCount();

$totalQuantity = Mage::getModel('checkout/cart')->getQuote()->getItemsQty();

$subTotal = Mage::getModel('checkout/cart')->getQuote()->getSubtotal();

$grandTotal = Mage::getModel('checkout/cart')->getQuote()->getGrandTotal();

Magento Override Core Controller

• 
  
 
• 

Example: Override ProductController.php

First create the following paths and files:

app/code/etc/modules/StickyLizard_CoreOverrides.xml

app/code/local/StickyLizard/CoreOverrides/etc/config.xml

app/code/local/StickyLizard/CoreOverrides/controllers/Catalog/ProductController.php

In app/code/etc/modules/StickyLizard_CoreOverrides.xml:

<config>

    <modules>

        <stickylizard_coreoverrides>

            <active>true</active>

            <codepool>local</codepool>

        </stickylizard_coreoverrides>

    </modules>

</config>

In app/code/local/StickyLizard/CoreOverrides/etc/config.xml:

<config>

    <modules>

        <stickylizard_coreoverrides>

            <version>0.1.0</version>

        </stickylizard_coreoverrides>

    </modules>

    <frontend>

        <routers>

            <catalog>

                <args>

                    <modules>

                        <stickylizard_coreoverrides before="Mage_Catalog">StickyLizard_CoreOverrides_Catalog</stickylizard_coreoverrides>

                    </modules>

                </args>

            </catalog>

        </routers>

    </frontend>

</config>

In app/code/local/StickyLizard/CoreOverrides/controllers/Catalog/ProductController.php

<!--?php

require_once Mage::getModuleDir('controllers', 'Mage_Catalog').DS.'ProductController.php';

class StickyLizard_CoreOverrides_Catalog_ProductController extends Mage_Catalog_ProductController

{

    public function viewAction()

    {

        echo "here I am";

        parent::viewAction();

Image resizer script

image_type = $image_info[2];
   if( $this->image_type == IMAGETYPE_JPEG ) {
      $this->image = imagecreatefromjpeg($filename);
   } elseif( $this->image_type == IMAGETYPE_GIF ) {
      $this->image = imagecreatefromgif($filename);
   } elseif( $this->image_type == IMAGETYPE_PNG ) {
      $this->image = imagecreatefrompng($filename);
   }
}
function save($filename, $image_type=IMAGETYPE_JPEG, $compression=75,
$permissions=null) {
   if( $image_type == IMAGETYPE_JPEG ) {
      imagejpeg($this->image,$filename,$compression);
   } elseif( $image_type == IMAGETYPE_GIF ) {
      imagegif($this->image,$filename);      
   } elseif( $image_type == IMAGETYPE_PNG ) {
      imagepng($this->image,$filename);
   }
   if( $permissions != null) {
      chmod($filename,$permissions);
   }
}
function output($image_type=IMAGETYPE_JPEG) {
   if( $image_type == IMAGETYPE_JPEG ) {
      imagejpeg($this->image);
   } elseif( $image_type == IMAGETYPE_GIF ) {
      imagegif($this->image);      
   } elseif( $image_type == IMAGETYPE_PNG ) {
      imagepng($this->image);
   }
}
function getWidth() {
   return imagesx($this->image);
}
function getHeight() {
   return imagesy($this->image);
}
function resizeToHeight($height) {
   $ratio = $height / $this->getHeight();
   $width = $this->getWidth() * $ratio;
   $this->resize($width,$height);
}
function resizeToWidth($width) {
   $ratio = $width / $this->getWidth();
   $height = $this->getheight() * $ratio;
   $this->resize($width,$height);
}
function scale($scale) {
   $width = $this->getWidth() * $scale/100;
   $height = $this->getheight() * $scale/100;
   $this->resize($width,$height);
}
function resize($width,$height) {
   $new_image = imagecreatetruecolor($width, $height);
   imagecopyresampled($new_image, $this->image, 0, 0, 0, 0, $width, $height,
$this->getWidth(), $this->getHeight());
   $this->image = $new_image;
}   
}
?>



The first example below will load a file named picture.jpg resize it to 250
pixels wide and 400 pixels high and resave it as picture2.jpg

load('picture.jpg');
 $image->resize(250,400);
 $image->save('picture2.jpg');
?>

If you want to resize to a specifed width but keep the dimensions ratio the
same then the script can work out the required height for you, just use the
resizeToWidth function.

load('picture.jpg');
 $image->resizeToWidth(250);
 $image->save('picture2.jpg');
?>

You may wish to scale an image to a specified percentage like the following
which will resize the image to 50% of its original width and height

load('picture.jpg');
 $image->scale(50);
 $image->save('picture2.jpg');
?>

You can of course do more than one thing at once. The following example
will create two new images with heights of 200 pixels and 500 pixels

load('picture.jpg');
 $image->resizeToHeight(500);
 $image->save('picture2.jpg');
 $image->resizeToHeight(200);
 $image->save('picture3.jpg');
?>

The output function lets you output the image straight to the browser
without having to save the file. Its useful for on the fly thumbnail
generation

load('picture.jpg');
 $image->resizeToWidth(150);
 $image->output();
?>

The following example will resize and save
an image which has been uploaded via a form

    
    
 
load($_FILES['uploaded_image']['tmp_name']);
    $image->resizeToWidth(150);
    $image->output();
 } else {
?>
