php - 如果列表中存在特定变量或单词，如何使用 PHP 隐藏 smth

Question

                    <? if (isset($menu_filter_sizes)) { ?>
                     <? for ($i = 0; $i < count($menu_filter_sizes); $i++) { ?>
                            <? if (!empty($menu_filter_sizes[$i]['name'])) { ?>                                    
                            <li>
                                <? if ($page->sp_size == $menu_filter_sizes[$i]['id']) { ?>
                                <? } else { ?><a href=""><? }; ?>
                                    <? echo $menu_filter_sizes[$i]['name']; ?>
                                <? if ($page->sp_size == $menu_filter_sizes[$i]['id']) { ?>
                                <? } else { ?></a><? }; ?>
                                (<? echo $menu_filter_sizes[$i]['quantity']; ?>)
                            </li>
                            <? }; ?>
                        <? }; ?>
                <? }; ?>

此代码生成一个具有不同值(例如大小)的列表。我的数据库中有一个名为“Nosize”的值。这对于没有尺寸的产品来说是有值(value)的。现在我有 PHP 代码，它输出列表中的所有值。

如何使用 php 通过名称 “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 (count($category) > 0) {$sqlquery .= " AND (";};
    for ($i = 0; $i < count($category); $i++) {
        if ($i == 0) {$sqlquery .= "$this->base.categoryid = '".sql($category[$i])."'";}
        else {$sqlquery .= " OR $this->base.categoryid = '".sql($category[$i])."'";};
    };
    if (count($category) > 0) {$sqlquery .= ")";};

    if (!empty($fbrand)) {$sqlquery .= " AND $this->base.brand = '".sql($fbrand)."'";};

    if (!empty($fpricefrom)) {$sqlquery .= " AND ($this->base.price >= '".sql($fpricefrom)."')";};
    if (!empty($fpriceto)) {

    };
    $sqlquery .= " GROUP BY $this->basesq.size";
    $result = mysql_query($sqlquery) or die(mysql_error()." in file: ".__FILE__.", line: ".__LINE__);
    return GetMySQLResultArray($result);
}

Answer 1

<? 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
                                
       } 
     } 
   } ?>

此外，您还在不需要的每一行打开和关闭 php 标签。

您需要将代码放在 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>
    
    <?                                        
      } 
    } 
   } 
 ?>
