Question

我想从下面的php代码中排除“id”介于1000和2000之间的产品：

    <?php
class ControllerModuleLatest extends Controller {
    protected function index($setting) {
        $this->language->load('module/latest');

        $this->data['heading_title'] = $this->language->get('heading_title');

        $this->data['button_cart'] = $this->language->get('button_cart');

        $this->load->model('catalog/product');

        $this->load->model('tool/image');

        $this->data['products'] = array();

        $data = array(
            'sort'  => 'p.date_added',
            'order' => 'DESC',
            'start' => 0,
            'limit' => $setting['limit']
        );

        $results = $this->model_catalog_product->getProducts($data);

        foreach ($results as $result) {








            if ($result['image']) {
                $image = $this->model_tool_image->resize($result['image'], $setting['image_width'], $setting['image_height']);
            } else {
                $image = false;
            }

            if (($this->config->get('config_customer_price') && $this->customer->isLogged()) || !$this->config->get('config_customer_price')) {
                $price = $this->currency->format($this->tax->calculate($result['price'], $result['tax_class_id'], $this->config->get('config_tax')));
            } else {
                $price = false;
            }

            if ((float)$result['special']) {
                $special = $this->currency->format($this->tax->calculate($result['special'], $result['tax_class_id'], $this->config->get('config_tax')));
            } else {
                $special = false;
            }

            if ($this->config->get('config_review_status')) {
                $rating = $result['rating'];
            } else {
                $rating = false;
            }

            $this->data['products'][] = array(
                'product_id' => $result['product_id'],
                'thumb'      => $image,
                'name'       => $result['name'],
                'price'      => $price,
                'special'    => $special,
                'rating'     => $rating,
                'reviews'    => sprintf($this->language->get('text_reviews'), (int)$result['reviews']),
                'href'       => $this->url->link('product/product', 'product_id=' . $result['product_id']),
            );



        }

        if (file_exists(DIR_TEMPLATE . $this->config->get('config_template') . '/template/module/latest.tpl')) {
            $this->template = $this->config->get('config_template') . '/template/module/latest.tpl';
        } else {
            $this->template = 'default/template/module/latest.tpl';
        }

        $this->render();
    }
}
?>

可能必须有一个“if（1000＆lt; $ result ['product_id']＆lt; 2000”）... 有什么建议？

提前谢谢

要快速解决问题，您需要做的就是在

之后直接添加if条件

foreach ($results as $result) {

条件将检查ID，如果匹配则会调用continue;：

    if ($product['product_id'] >= 1000 && $product['product_id'] <= 2000) {
        continue;
    }

但更清晰的解决方案是让SQL知道你想通过在SQL中添加WHERE子句来省略1000 ... 2000范围内的ID（仅限示例）：

SELECT *
FROM product p
WHERE p.product_id NOT BETWEEN 1000 AND 2000
ORDER BY p.date_added DESC
LIMIT <LIMIT>
