所以我很困惑,我使用的是模板,并且有一个显示类别的侧菜单,当您在类别上按一个下拉菜单时,该菜单具有与初始类别中ID相关的相应类别。当我按类别时,它并没有给我想要的结果。单击href时,它会为我提供初始类别的结果,而不是与单击的href id对应的类别的结果。不知道我在做什么错? current results with code below
<div class="catagories-menu">
<ul id="menu-content2" class="menu-content collapse show">
<?
$database = new DB();
$query = "select * from category where cat_SubCat IS NULL";//
$rows = $database->get_results($query);
foreach ($rows as $row)//foreach database result
{
echo"<li data-toggle='collapse' data-target='#$row[cat_Name]' class='collapsed' >
<a href='#' id='$row[cat_ID]'>" . $row[cat_Name] . "</a>
<ul class='sub-menu collapse' id='$row[cat_Name]'>
<li><a href='#'>All</a></li>";
$database = new DB();//creating an object from the class
$query2 = "select * from category where cat_SubCat=" .$row[cat_ID]."";//
$subs = $database->get_results($query2);
foreach ($subs as $sub)//foreach database result
{
echo"<li><a href='prodDetail.php?cat_ID=".$sub[cat_ID]."&cat_SubCat=".$sub[cat_SubCat]."' class='list-group-item'>" . $sub[cat_Name] . "</a></li>";
}
echo"</ul>
</li>";
}
?>
</ul>
</div>
我正在寻找要首先打印的空类别,并在下面打印与空相关的类别
desired reults
从Khan的条目中更新了代码,并将$ subs = $ database-> get_results($ query);
替换为
$ subs = $ database-> get_results($ query2);
它部分起作用。代码不允许对前两个类别进行下拉,但其他类别的显示却很混乱
答案 0 :(得分:0)
您在子菜单中使用的是查询,而不是query2
foreach ($rows as $row)//foreach database result
{
echo"<li data-toggle='collapse' data-target='#$row[cat_Name]' class='collapsed' >
<a href='#' id='$row[cat_ID]'>" . $row[cat_Name] . "</a>
<ul class='sub-menu collapse' id='$row[cat_Name]'>
<li><a href='#'>All</a></li>";
$database2 = new DB();//creating an object from the class
$query2 = "select * from category where cat_SubCat=" .$row[cat_ID]."";//
$subs = $database2->get_results($query2);
foreach ($subs as $sub)//foreach database result
{
echo"<li><a href='prodDetail.php?cat_ID=".$sub[cat_ID]."&cat_SubCat=".$sub[cat_SubCat]."' class='list-group-item'>" . $sub[cat_Name] . "</a></li>";
}
echo"</ul>
</li>";
}
