Question

我有一个不同位置的多站点。我们必须创建一个自定义区域来放置标题和元信息。现在，标题仅输出在主题选项中设置的公司名称的短代码。我们必须为城市和州提供其他短信码。我更新了标题区域的代码，但它只适用于状态的最后一行代码。我需要所有三个代码才能工作。

**if($get_location['option_value'] == get_bloginfo('name'))
                {
                    # grab title tag from page ID
                    $get_title = mysql_fetch_array(mysql_query('SELECT meta_value FROM wp_'.$number.'_postmeta WHERE meta_key = \'title\' AND post_id = \''.$post->ID.'\''));

                    # grab company name
                    $get_company_result = mysql_fetch_array(mysql_query('SELECT option_value FROM '.$td[0].' WHERE option_name = \'option_tree\''));

                    $get_city_result = mysql_fetch_array(mysql_query('SELECT option_value FROM '.$td[0].' WHERE option_name = \'option_tree\''));

                    $get_state_result = mysql_fetch_array(mysql_query('SELECT option_value FROM '.$td[0].' WHERE option_name = \'option_tree\''));

                    # clearn up returned value
                    $company = unserialize($get_company_result['option_value']);

                    $city = unserialize($get_city_result['option_value']);

                    $state = unserialize($get_state_result['option_value']);

                    # replace shortcode with company name
                    $return_title = str_replace('[company_name]',$company['company_name'], $get_title['meta_value']);
                    # replace shortcode with company name
                    $return_title = str_replace('[city]',$city['city'], $get_title['meta_value']);
                    # replace shortcode with company name
                    $return_title = str_replace('[state]',$state['state'], $get_title['meta_value']);

                    # if values are not empty/null
                    if($get_title['meta_value'] != '' or $get_title['meta_value'] != NULL)
                    {
                        $title = $return_title;
                    }**

您要更新相同的变量$return_title 3次。请改用此代码：

$return_title = $get_title['meta_value']; //put into a variable
# replace shortcode with company name
$return_title = str_replace('[company_name]',$company['company_name'], $return_title); //override variable with str_replace
# replace shortcode with company name
$return_title = str_replace('[city]',$city['city'], $return_title); //override variable with str_replace
# replace shortcode with company name
$return_title = str_replace('[state]',$state['state'], $return_title); //override variable with str_replace
