Opencart最低订购价格不包括一个类别 [英] Opencart minimum order price exclude one category

问题描述

我正在使用opencart，并且已成功为所有交易添加了最低订单价格. 这是我使用的代码:

I am using opencart and successfully added minimum order price for all transactions. This is the code I used:

<?php if ($this->cart->getSubtotal() >= 10) { ?>
<div id="payment"><?php echo $payment; ?></div>
<?php } else { ?>
<div class="warning">Minimum 10 Euro to checkout</div>
<?php }  ?> 

现在，我要排除一个类别，以便可以购买该类别中的9美元产品.

Now I want to exclude one category out of it so that $9 product from that category can be bought.

更新1: 非常感谢shadyyx的帮助

Update 1: Thank you so much for the help shadyyx

我尝试了shadyyx方法，但出现此错误: 此行中的unexpected T_BOOLEAN_OR

I tried shadyyx method but I am getting this error: unexpected T_BOOLEAN_OR in this line

<?php if ($this->cart->getSubtotal() >= 10 || $this->cart->productsAreInCategory(1)) { ?>

更新2:我尝试了此操作，但弹出了一个对话框，提示只是错误和确定按钮 <?php if (($this->cart->getSubtotal() >= 10) || $this->cart->productsAreInCategory(1)) { ?>

Update 2: I tried this but it gave a pop up saying just error and ok button <?php if (($this->cart->getSubtotal() >= 10) || $this->cart->productsAreInCategory(1)) { ?>

我尝试了这个 <?php if (($this->cart->getSubtotal() >= 10) || ($this->cart->productsAreInCategory(1))) { ?> 它没有给出任何错误，并且执行相同的工作(所有订单的最低金额，与类别ID无关)

I tried this <?php if (($this->cart->getSubtotal() >= 10) || ($this->cart->productsAreInCategory(1))) { ?> it did not give any error and does same work (min amount for all orders regardless of category id)

推荐答案

我会这样:

扩展system/library/cart.php并添加方法:

public function productsAreInCategory($category_id) {
    $product_ids = array();
    foreach($this->getProducts() as $product) {
        $product_ids[] = $product['product_id'];
    }

    $categories = $this->db->query('SELECT category_id FROM ' . DB_PREFIX . 'product_to_category WHERE product_id IN (' . implode(',', $product_ids) . ')')->rows;

    $category_ids = array();
    foreach($categories as $category) {
        $category_ids[] = $category['category_id'];
    }

    if(in_array($category_id, $category_ids) {
        return true;
    }

    return false;
}

此方法应接受$category_id参数进行测试，并应加载购物车中所有产品的类别.第一次匹配后，返回true，如果没有匹配，则返回false.您现在可以通过以下方式使用此方法:

This method should accept a $category_id parameter to test against and should load categories for all products in cart. After first match a true is returned, if no match, a false is returned. You can now use this method this way:

<?php if (($this->cart->getSubtotal() >= 10) || $this->cart->productsAreInCategory(1)) { ?>
<div id="payment"><?php echo $payment; ?></div>
<?php } else { ?>
<div class="warning">Minimum 10 Euro to checkout</div>
<?php }  ?>

只需用正确的ID替换$this->cart->productsAreInCategory(1)中的类别ID.

Just replace the category ID in $this->cart->productsAreInCategory(1) with the correct one.
