限制一些添加到购物车的数量 [英] restrict some quantity for adding to cart

问题描述

我们需要预购/延期订购"功能[用户可以购买缺货的产品]

we needed "pre-order/Back order" feature [ user can buy out-of-stock Products ]

所以我们写了定制模块.它是如何工作的，如果我们设置值

so we wrote custom module. how it works is , if we set value

"是"作为预订属性，它将允许预订，

"yes" to pre order attribute, it will allow for pre-order,

对于"否"，它不会在视图页面中显示预定"按钮.

for "NO", it will not show "Pre order" button in view page.

但问题是用户可以输入任意数量的数量&添加到购物车项目.

but problem is user can enter any number of quantity & add to cart items.

我们需要的是我们在后端输入的数量，只有它可以允许大量的数量添加到购物车中.

what we need is what quantity we enter in backend, only it should allow that much quantity to add-to-cart.

<?php $_collectionSize = $_productCollection->count() ?>
    <?php $_columnCount = $this->getColumnCount(); ?>
    <?php $i=0; foreach ($_productCollection as $_product): ?>
        <?php if ($i++%$_columnCount==0): ?>
        <ul class="products-grid">
        <?php endif ?>
            <li class="item<?php if(($i-1)%$_columnCount==0): ?> first<?php elseif($i%$_columnCount==0): ?> last<?php endif; ?>">

                <h2 class="product-name"><a href="<?php echo $_product->getProductUrl() ?>" title="<?php echo $this->stripTags($_product->getName(), null, true) ?>"><?php echo $_helper->productAttribute($_product, $_product->getName(), 'name') ?></a></h2>

                <?php echo $this->getPriceHtml($_product, true) ?>
                <div class="actions">
                    <?php if($_product->isSaleable()): ?>
                        <?php if($_product->getPreOrder()): ?>
                        <button type="button" title="<?php echo $this->__('Pre-Order') ?>" class="button btn-cart" onclick="setLocation('<?php echo $this->getAddToCartUrl($_product) ?>')"><span><span><?php echo $this->__('Pre-Order') ?></span></span></button>

                        <?php endif; ?>
                    <?php else: ?>
                        <p class="availability out-of-stock"><span><?php echo $this->__('') ?></span></p>
                    <?php endif; ?>

                </div>
            </li>
        <?php if ($i%$_columnCount==0 || $i==$_collectionSize): ?>
        </ul>
        <?php endif ?>
        <?php endforeach ?>
        <script type="text/javascript">decorateGeneric($$('ul.products-grid'), ['odd','even','first','last'])</script>
    <?php endif; ?>
