我正在一個項目,我需要通過電子郵件發送兩個警報。我已經實施了一個電子郵件提醒,它的工作正常,我收到狀態消息後成功完成電子郵件交付完成,但對於第二個我已經添加了一列作爲service_status。雖然電子郵件功能工作正常,但它沒有顯示完成,而是顯示空值或空值,但數據庫中的值是「已完成」...這裏是我的代碼片段,我需要顯示已完成的結果空值是從MySQL返回通過PHP
<?php
if(count($det)){
?>
<?php for($i=0;$i<count($det);$i++)

</tr>
<?php }
}
else{ echo '<div class="row"><p style="text-align:center;"><strong>No records found</strong></p></div>';
} ?>
</table>
的問題是這行代碼
<td class="bottomcolor"><?php echo isset($det[$i]['reminder2_status'])?($det[$i]['service_status']=='c')?'Completed':'Pending':'';?> </td>
這是返回空或空值
