大概简单的PHP if/else语句不起作用

Question

我似乎遇到了另一块似乎是超级基本的PHP的问题，但它不适用于我。

我的客户（房地产网站）需要能够有没有价格的属性是“价格应要求”或“拍卖”。目前，将价格字段留空仅允许一个。

我试图改变如下代码：

$listing_price_labels = array(
‘sold’ => __(‘Sold’, ‘wpsight’), 
‘rented’ => __(‘Rented’, ‘wpsight’), 
‘request’ => __(‘Price on request’, ‘wpsight’), 
‘auction’ => __(‘Auction’, ‘wpsight’), ***– Added this line*** 
); 

哪里这段代码被发现...

if(is_admin()) 
     $listing_price .= ‘<br />’ . wpsight_get_price_value(); 

    } elseif(empty($listing_price)) { 

     // When no price available Price on request 
     $listing_price = ‘<span class=”listing-price-on-request”>’ . $listing_price_labels['request'] . ‘</span><!– .listing-price-on-request –>’; 

    } elseif($listing_price = ‘auction’) { 

     // When price field contains ‘auction’ (case sensitive) 
     $listing_price = ‘<span class=”listing-price-on-request”>’ . $listing_price_labels['auction'] . ‘</span><!– .listing-price-on-request –>’; 

    } 



    function wpsight_get_price($post_id = '') { 

     // Get post ID from $post_id 

     if(empty($post_id)) 
      $post_id = get_the_ID();  

     // If still empty, return false 

     if(empty($post_id)) 
      return false; 

     // Set listing price labels 

     $listing_price_labels = array(
      'sold' => __('Sold', 'wpsight' ), 
      'rented' => __('Rented', 'wpsight' ), 
      'request' => __('Price on request', 'wpsight'), 
      'auction' => __('Auction', 'wpsight'), 
      ); 

     $listing_price_labels = apply_filters('wpsight_get_price_labels', $listing_price_labels); 

     // Get listing price 
     $listing_price = wpsight_get_price_value(); 

     // Get custom fields 

     $custom_fields   = get_post_custom($post_id); 
     $listing_status   = isset($custom_fields['_price_status'][0]) ? $custom_fields['_price_status'][0] : false; 
     $listing_availability = isset($custom_fields['_price_sold_rented'][0]) ? $custom_fields['_price_sold_rented'][0] : false; 

     // Create price output 

     if(! empty($listing_availability)) { 

      // When listing is not available 

      $sold_rented = ($listing_status == 'sale') ? $listing_price_labels['sold'] : $listing_price_labels['rented']; 

      // Display sold/rented bold red in admin 
      $style = is_admin() ? ' style="color:red;font-weight:bold"' : false; 

      $listing_price = '<span class="listing-price-sold-rented"' . $style . '>' . $sold_rented . '</span><!-- .listing-price-sold-rented -->'; 

      if(is_admin()) 
       $listing_price .= '<br />' . wpsight_get_price_value(); 

     } elseif(empty($listing_price)) { 

      // When no price available Price on request 
      $listing_price = '<span class="listing-price-on-request">' . $listing_price_labels['request'] . '</span><!-- .listing-price-on-request -->'; 

     } elseif($listing_price == "auction") { 

      // When price field contains 'auction' (case sensitive) 
      $listing_price = '<span class="listing-price-on-request">' . $listing_price_labels['auction'] . '</span><!-- .listing-price-on-request -->'; 

     } 

     return apply_filters('wpsight_listing_price', $listing_price); 

    } 

我敢肯定，我的语法必须仅仅是错误的，因为在地方，它的代码使任何写入价格栏显示“拍卖”的任何财产。

任何人都可以看到我做错了什么吗？

尝试：

if(is_admin()){ 
    $listing_price .= ‘<br />’ . wpsight_get_price_value(); 

    } elseif(empty($listing_price)) { 

    // When no price available Price on request 
    $listing_price = ‘<span class=”listing-price-on-request”>’ . $listing_price_labels['request'] . ‘</span><!– .listing-price-on-request –>’; 
} 

BTW它不推荐使用if(is_admin())因为它的只适用于1线。
