此代码生成具有不同值（例如大小）的列表。我在我的数据库中有一个名为"Nosize"的值。这是没有尺寸的产品的价值。呈现我拥有的 PHP 代码输出列表中的所有值。

如何使用 php 以名称“Nosize”隐藏该值？？？并仅显示其他值。换句话说，显示除“Nosize”之外的所有值。

MYSQL：

function GetShopFilterSizes($shopid,$category,$fcolor,$fbrand,$fytpe,$fpricefrom,$fpriceto){
    $thisdate = date("Y-m-d H:i:s", time());
    $sqlquery = "SELECT DISTINCT($this->basesq.size) AS id, $this->basesize.alias, $this->basesizelang.name, COUNT(DISTINCT($this->base.id)) as quantity FROM $this->base LEFT JOIN $this->basesq ON $this->basesq.productid = $this->base.id LEFT JOIN $this->basesize ON $this->basesq.size = $this->basesize.id LEFT JOIN $this->basesizelang ON $this->basesize.id = $this->basesizelang.sizeid AND $this->basesizelang.lang =  '".sql($this->thislang)."'

<? if (isset($menu_filter_sizes)) { 
    for ($i = 0; $i < count($menu_filter_sizes); $i++) { 
    if($menu_filter_sizes[$i]['size']!='Nosize') {//check if size is not equal to Nosize
                                
       } 
     } 
   } ?>

您还可以在不需要的每一行打开和关闭 php 标签。

你需要把你的代码放在 div 之外

      <? if (isset($menu_filter_sizes)) { 
                for ($i = 0; $i < count($menu_filter_sizes); $i++) { 
                if($menu_filter_sizes[$i]['size']!='Nosize') {//check if size is not equal to Nosize
    
    ?>
       <div class="box manufacturers">
    
    
        </div>
    
    <?                                        
      } 
    } 
   } 
 ?>
