php - 如何在类别内的广告列表中显示自定义字段

Question

我从管理面板添加了自定义字段，它显示在广告的详细信息页面上，但我也想显示在列表页面上，你能告诉我我需要编码的文件、PHP 文件、CSS 或类文件吗. 而且我不知道 PHP 编码，但知道 .Net。提前致谢！

If I'm not mistaking, the Listing pages is the search page (where the list of items is displayed).

In order to do that you'll have to look for search or after_search hooks in oc-includes/osclass/controller/Search.php.

You'll need to have a DAO object too, this tutorial should get you started.

osc_add_hook('after_search', function() {
    if (osc_is_search_page()) {
        osc_reset_items();
        while(osc_has_items()) {
            $detail = // Get your discount info for osc_item_id()
            if(isset($detail['fk_i_item_id'])) {
                $result[osc_item_id()] = $detail;
            }
        }
        View::newInstance()->_exportVariableToView("your_plugin_name", $result);
        osc_reset_items();
    }
});

Then, in your theme search.php file, you can retrieve your discount info with something like this:

$discounts = __get("your_plugin_name");
while(osc_has_items()) {
    $discount = $discounts[osc_item_id()];
}
