mysql - 如何在 Opencart 中内爆数据？

Question

我想用逗号分解平台数据，例如:Windows、Mac、Linux。

我尝试了不同的选择，但仍未找到解决方案。所以我有一个问题，如何爆破我用这段代码获得的数据？

<?php

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

$query = $this->db->query("SELECT p2p.platform_id, p.parent_id FROM "
. DB_PREFIX . "platform p LEFT JOIN " . DB_PREFIX . "product_to_platform p2p
ON p.platform_id=p2p.platform_id WHERE product_id='" . $product_id . "' AND parent_id=0");

$prodplatforms = $query->rows;

foreach($prodplatforms as $prodplatform){

    $platform_id = $prodplatform['platform_id'];
    $platform_info = $this->model_catalog_platform->getPlatform($platform_id);
    $caturl = (HTTP_SERVER . 'index.php?route=product/platform&path=' . $platform_id);
    $str = $platform_info['name'];

        echo '<a href="' . $caturl . '">' . $str . '</a>';
}
?>

您只需要一点点编辑 - 而不是 $str = $platform_info['name']; 这样做:

// ...
$prodplatforms = $query->rows;

$platforms = array();

foreach($prodplatforms as $prodplatform){
    $platform_id = $prodplatform['platform_id'];
    $platform_info = $this->model_catalog_platform->getPlatform($platform_id);
    $caturl = (HTTP_SERVER . 'index.php?route=product/platform&path=' . $platform_id);
    $platforms[] = $platform_info['name'];
}

echo '<a href="' . $caturl . '">' . implode(', ', $platforms) . '</a>';

但现在看代码我猜你只是想让每个平台名称链接到它的平台 URL...

查看您的代码，我猜您是在模板文件中完成所有这些工作。也许您只是将来自您的 Controller 、模型和模板的代码放在一起——这没问题，但如果您真的在一个模板中完成这一切，请将代码拆分到各个层:

Controller :

$this->load->model('catalog/platform');
$prodplatforms = $this->model_catalog_platform->getPlatforms($product_id);

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

foreach($prodplatforms as $prodplatform){
    $platform_id = $prodplatform['platform_id'];
    $platform_info = $this->model_catalog_platform->getPlatform($platform_id);
    $caturl = (HTTP_SERVER . 'index.php?route=product/platform&path=' . $platform_id);
    $this->data['platforms'][] = '<a href="' . $caturl . '">' . $platform_info['name'] . '</a>';
}

模型(catalog/model/catalog/platform.php):

public function getPlatforms($product_id) {
    $query = $this->db->query("SELECT p2p.platform_id, p.parent_id FROM " . DB_PREFIX . "platform p LEFT JOIN " . DB_PREFIX . "product_to_platform p2p ON p.platform_id=p2p.platform_id WHERE product_id='" . $product_id . "' AND parent_id=0");

    return $query->rows;
}

查看模板:

<div><?php echo implode(', ', $platforms); ?></div>
