我为此代码获得了未定义索引:
<table align="center" border="2">
<tr>
<td align="center"> <font color=""> Quantity Sold:</td>
<td align="center"> <font color=""> Month:</td>
</tr>
<?php
include 'connect.php';
$bogart=mysqli_query($con," SELECT `month`, sum(q_sold) as sold_sum
FROM `samsung_store` group by `month` order by sold_sum desc
LIMIT 1 ") or die (mysql_error());
$count=mysqli_num_rows($bogart);
while($baragan=mysqli_fetch_array($bogart)){
if($count % 2 == 0){
$color="#EDEDED";
$count--;
}
else{
$color="white";
$count--;
}
?>
<tr bgcolor="<?php echo $color?>">
<td> <?php echo $baragan['q_sold']?></td>
<td> <?php echo $baragan['month'] ?></td>
</tr>
<?php
}
?>
</form>
</table>
我只需要删除错误。我不知道我怎么试着在开头的时候加上“@”符号:但是没有用?
$博加特= msqli_query
对不起,我是初学者,请光一点。谢谢。
答案 0 :(得分:5)
<td> <?php echo $baragan['q_sold']?></td>
当您在查询中选择名为q_sold
的别名时,为什么要访问索引sold_sum
?
将其更改为:
<td> <?php echo $baragan['sold_sum']?></td>
提示:使用print_r($baragan);
