[2019年3月20日04:24:48 America / New_York] PHP注意：未定义的变量：第246行的/home/wwwrsfcrm/public_html/airportextras/admin/advance-settings.php中的end_date

这是我的代码

<?php include('inc/header.php'); ?>
<?PHP
   session_start();
   if($_SESSION['username']=='' && $_SESSION['password']==''){
    header('Location: index');

}
?>

<?php include('inc/sidebar.php'); ?>
<?php 
$currentid = $_SESSION['aid'];
$con = mysqli_connect("localhost","root","password","database");

//Check connection
if (mysqli_connect_errno())
{
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
}


 $query = "SELECT * FROM disabled_dates WHERE agent_id = '$currentid'";
 $result = mysqli_query($con, $query);
 if(mysqli_num_rows($result) > 0)
 {
    while($row = mysqli_fetch_array($result))
    {
        $start_date = $row['start_date'];
        $end_date = $row['end_date'];                   
    }
  }
?>

Answer 1

解决方案1： 在While / if / else之前：

$start_date = $end_date = NULL;

在html中：

<?php echo (!empty($end_date))?$end_date:"0000/00/00"; ?>
//same with start_date

//or

<?php if(!empty($end_date)){
    echo $end_date;
}else{
    echo "0000/00/00";
}?>

解决方案2： 仅在html中：

<?php echo (isset($end_date))?$end_date:"0000/00/00"; ?>
//same with start_date

未定义的变量，即使我定义了它
