如何找出哪个变量是在另一个之后创建的？

  • 772

if(isset($catalog_filter_array['category'])) {
    $category_term = get_term_by('slug', $catalog_filter_array['category'], 'girls');
    $term = $category_term;

}
if(isset($catalog_filter_array['service'])) {
    $service_term = get_term_by('slug', $catalog_filter_array['service'], 'services');

    $term = $service_term;
}
if(isset($catalog_filter_array['city'])) {
    $city_term = get_term_by('slug', $catalog_filter_array['city'], 'city');

    $term = $city_term;
}

类似这段代码的东西。如果所有 3 个条件都为真，则应该只有 1 个变量术语，那么只有最后一个 $term 将在那里，但不是它最后创建的事实。有没有办法检查最后创建的更改？

    if(isset($catalog_filter_array['category'])) {
    $category_term = get_term_by('slug', $catalog_filter_array['category'], 'girls');
    $term = $category_term;

} else if(isset($catalog_filter_array['service'])) {
    $service_term = get_term_by('slug', $catalog_filter_array['service'], 'services');

    $term = $service_term;
} else if(isset($catalog_filter_array['city'])) {
    $city_term = get_term_by('slug', $catalog_filter_array['city'], 'city');

    $term = $city_term;
}

  2. 好吧，比如，添加某个开关，并检查它是否已被激活：

    $triger = false;

if (isset($catalog_filter_array['category'])) {
    $category_term = get_term_by('slug', $catalog_filter_array['category'], 'girls');
    $term = $category_term;
    $triger = true;
}

if (! $triger && isset($catalog_filter_array['service'])) {
    $service_term = get_term_by('slug', $catalog_filter_array['service'], 'services');
    $term = $service_term;
    $triger = true;
}

if (! $triger && isset($catalog_filter_array['city'])) {
    $city_term = get_term_by('slug', $catalog_filter_array['city'], 'city');
    $term = $city_term;
}
