如何在magento中获得产品形象

Question

I am using Magento community version 1.5.1.0.

I need to get a product have image or not. If a product have no image we want to assign its category image instead of magento default image.

How can I find that product have image or not?

Answer 1

Use the following code

<?php
        ini_set('display_errors','on');
        require_once 'app/Mage.php';
        Mage::app('default');
        $products = Mage::getModel('catalog/product')->load(1); //Product ID
        echo "<pre>";
        //print_r($products);
        echo $products->getImage();
        echo "<br>";
        echo $products->getSmallImage();
        echo "<br>";
        echo $products->getThumbnail();
        echo "<br>";
        echo Mage::helper('catalog/image')->init($products, 'small_image')->resize(163,100); // resize function is used to resize image
        echo "<br>";
        echo Mage::helper('catalog/image')->init($products, 'image')->resize(400,400);
    ?>

Answer 2

$product->getImage();

Use the above code, it gives the image if product have or it return the key " no_selection "

if($product->getImage() == 'no_selection')
{
     // PRODUCT HAVE NO IMAGE
}
else
{
     // PRODUCT HAVE IMAGE
}

With this we can findout that images was upload or not for a product.

Answer 3

尝试这个

if ($_product->getImage() != 'no_selection' && $_product->getImage()){put your category image retrive code }

Answer 4

When you call $your_product = Mage::getModel('catalog/product') in result you can find the media array details. So if you check for count of that array, you know the number of images associated to a product; if count is zero, no images are associated.

So:

if(count($your_product['media_gallery']['images']) > 0)
// PRODUCT HAVE IMAGE
else
// PRODUCT HAVE NO IMAGE
