How could I cache images that I'm pulling from a magento database through ajax?
- by wes
Here's script being called through ajax:
<?php
require_once '../app/Mage.php';
umask(0);
/* not Mage::run(); */
Mage::app('default');
$cat_id = ($_POST['cat_id']) ? $_POST['cat_id'] : NULL;
try {
$category = new Mage_Catalog_Model_Category();
$category->load($cat_id);
$collection = $category->getProductCollection();
$output = '<ul>';
foreach ($collection as $product) {
$cProduct = Mage::getModel('catalog/product');
$cProduct->load($product->getId());
$output .= '<li><img id="'.$product->getId().'" src="' . (string)Mage::helper('catalog/image')->init($cProduct, 'small_image')->resize(75) . '" class="thumb" /></li>';
}
$output .= '</ul>';
echo $output;
} catch (Exception $e) {
echo 'Caught exception: ', $e->getMessage(), "\n";
}
I'm just passing in the Category ID, which I've tacked onto the navigation links, then doing some work to eventually just pass back all product images in that category.
I'm using this on a drag and drop build-a-bracelet type of application, and the amount of images returned is sometimes in the 500s. So it get's pretty held up during transmission, sometimes 10 seconds or so.
I know I'd do good by caching them some way, just not sure how to go about it. Any help is much appreciated.
Thanks.
