Magento产品列表页加入购物车带数量：在list.phtml中，以list列表模式为例：

<?php if($_product->isSaleable()): ?>
<p>

<form action="<?php echo $this->getAddToCartUrl($_product) ?>" method="post" id="product_addtocart_form_<?php echo $_product->getId()?>"<?php if($_product->getOptions()): ?> enctype="multipart/form-data"<?php endif; ?>>
<?php if(!$_product->isGrouped()): ?>
<label for="qty"><?php echo $this->__('Qty') ?>:</label>
<input type="text" name="qty" id="qty" maxlength="12" value="<?php echo ($this->getMinimalQty($_product)?$this->getMinimalQty($_product):1) ?>" />
<?php endif; ?>
<button type="button" onclick="this.form.submit()"><span><span><span><?php echo $this->__('Add to Cart') ?></span></span></span></button>
</form>

</p>
<?php else: ?>
<p><span><?php echo $this->__('Out of stock') ?></span></p>
<?php endif; ?>
