我正在查询它正在提取的记录,但它显示的是一个奇怪的empty record
,这在数据库中甚至都不常见。
额外记录表示列表中有一个额外的空<li>
。
$ dba是数据库连接。
$dba=mysqli_connect('127.0.0.1','root','','store');
foreach
无效。
请帮忙解决。
<?php include ('inc/db.php');
$zmcats = "select i.ename as iname,c.ename as cname, c.id as cid
from items i
inner join categories c on c.id = i.cat_id
where i.view > 4
and c.id = i.cat_id
and c.status = 1
group by c.id
";
$zmcat = $dba->query($zmcats);
//$zzmcat = array();
while ($zzmcat[] = $zmcat->fetch_array(MYSQLI_ASSOC)){}
foreach ($zzmcat as $zcatzn) {
?>
<li class="category-list list-parent"><a href="#"><?php echo $zcatzn["cname"]; ?></a>
<ul class="list-child">
<?php
$q = "SELECT id, ename FROM items
WHERE view > 4 and status = 1 and cat_id='".$zcatzn['cid']."' ";
$qq = $dba->query($q);
while ($product = $qq->fetch_array(MYSQLI_ASSOC)) {
?>
<li class="category-list"><a href="#">
<?php echo $product['ename']; ?>
</a></li>
<?php } ?>
</ul>
</li>
<?php } ?>

while循环之后的foreach循环是不必要的,只需使用简单的while循环
x,y
