How to get sold quantity of product in magento

If you want to have it so that it only shows quantity sold on the product page on items that are currently on sale.. use the following., There will also be an alert for customers when there is only 1 remaining in stock.Then use the following code.

<?php 
$_finalPrice = $this->helper('tax')->getPrice($_product, $_product->getFinalPrice());$_regularPrice = $this->helper('tax')->getPrice($_product, $_product->getPrice());
if ($_regularPrice != $_finalPrice):$sku = nl2br($_product->getSku());$to = $_product->getResource()->formatDate(time());$from = $_product->getResource()->formatDate(time() - 60 * 60 * 24 * 1);$_productCollection = Mage::getResourceModel('reports/product_collection')
->addOrderedQty($from, $to, true)
->addAttributeToFilter('sku', $sku)
->setOrder('ordered_qty', 'desc')
->getFirstItem();$product = $_productCollection;

echo 'Already Bought Today '.(int)$product->ordered_qty; 
endif;?>
<?php if ((int) Mage::getModel('cataloginventory/stock_item')->loadByProduct($_product)->getQty()==1): ?><p style="color:#990000; padding:5px 0; text-align:right;"><strong>ONLY 1 LEFT IN STOCK!</strong></p><?php endif; ?>

Or if you want to show stock sold on the product page for the entire duration the product has been active, use the following

<?php 

$sku = nl2br($_product->getSku());$_productCollection = Mage::getResourceModel('reports/product_collection')
->addOrderedQty()
->addAttributeToFilter('sku', $sku)
->setOrder('ordered_qty', 'desc')
->getFirstItem();$product = $_productCollection;

echo 'Already Bought '.(int)$product->ordered_qty; ?>

and finally if you want to just just on the page how many have been sold of the product for today, use the following

<?php 
$sku = nl2br($_product->getSku());$to = $_product->getResource()->formatDate(time());$from = $_product->getResource()->formatDate(time() - 60 * 60 * 24 * 1);$_productCollection = Mage::getResourceModel('reports/product_collection')
->addOrderedQty($from, $to, true)
->addAttributeToFilter('sku', $sku)
->setOrder('ordered_qty', 'desc')
->getFirstItem();$product = $_productCollection;

echo 'Quantity Ordered Today '.(int)$product->ordered_qty; 
endif;?>

Just copy and paste into your view.phtml file, into a suitable place :)

How to resize Image in magento

Here is the custom image resize function. This function will resize image proportionally.




/**
* Resize Image proportionally and return the resized image url
*
* @param string $imageName name of the image file
* @param integer|null $width resize width
* @param integer|null $height resize height
* @param string|null $imagePath directory path of the image present inside media directory
* @return string full url path of the image
*/
public function resizeImage($imageName, $width=NULL, $height=NULL, $imagePath=NULL)
{
$imagePath = str_replace("/", DS, $imagePath);
$imagePathFull = Mage::getBaseDir('media') . DS . $imagePath . DS . $imageName;

if($width == NULL && $height == NULL) {
$width = 100;
$height = 100;
}
$resizePath = $width . 'x' . $height;
$resizePathFull = Mage::getBaseDir('media') . DS . $imagePath . DS . $resizePath . DS . $imageName;

if (file_exists($imagePathFull) && !file_exists($resizePathFull)) {
$imageObj = new Varien_Image($imagePathFull);
$imageObj->constrainOnly(TRUE);
$imageObj->keepAspectRatio(TRUE);
$imageObj->resize($width,$height);
$imageObj->save($resizePathFull);
}

$imagePath=str_replace(DS, "/", $imagePath);
return Mage::getBaseUrl("media") . $imagePath . "/" . $resizePath . "/" . $imageName;
}

You can write the following code in template (.phtml) file to display the resized image:

<img src="<?php echo Mage::helper('moduleName')->resizeImage('abc.jpg', 400, 300, 'xyz/image'); ?>" alt="resized image" />

Template Hints for the Magento Admin

Simply paste the following into

app/code/core/Mage/Adminhtml/Block/Template.php

public function fetchView($fileName)

{

Varien_Profiler::start($fileName);

extract ($this->_viewVars);

$do = $this->getDirectOutput();

if (!$do) {

ob_start();

}

echo '<div style="position:relative;

border:1px dotted red; margin:6px 2px; 




padding:18px 2px 2px 2px; zoom:1;">




<div style="position:absolute; left:0; top:0; padding:2px 5px; 

background:red; color:white; font:normal 11px Arial; text-align:left !important; 

z-index:998;" onmouseover="this.style.zIndex=\'999\'" onmouseout="this.style.zIndex=\'998\'"

title="'.$fileName.'">'.$fileName.'</div>';

$thisClass = get_class($this);

echo '<div style="position:absolute; 

right:0; top:0; padding:2px 5px; background:red; color:blue; font:normal 11px Arial; 

text-align:left !important; z-index:998;" onmouseover="this.style.zIndex=\'999\'"

onmouseout="this.style.zIndex=\'998\'" title="'.$thisClass.'">'.$thisClass.'</div>';

try {

include $this->_viewDir . DS . $fileName;

} catch (Exception $e) {

ob_get_clean();

throw $e;

}

echo '</div>';

if (!$do) {

$html = ob_get_clean();

} else {

$html = '';

}

Varien_Profiler::stop($fileName);

return $html;

}

before the last closing brace }.

Just be sure to remove the code again then you are finished. If there is enough demand for it I might package the change up into a new MageBase extension.
