嗨，我是新的php和mysql，我已经绞尽脑汁找出我做错了什么。
有人能检查一下我的密码吗？
我理解这个错误，但似乎找不到解决办法。
注意：第19行的未定义索引：cid in/applications/xampp/xamppfiles/htdocs/ibelievine/editcomments.php
environment.inc.php公司：
<?php
include'dbh.inc.php';
function setComments($conn) {
if(isset($_POST['commentSubmit'])) {
$uid = $_POST['uid'];
$date = $_POST['date'];
$message = $_POST['message'];
$sql = "INSERT INTO environments (uid, date, message) VALUES
('$uid','$date', '$message' )";
$result = mysqli_query($conn, $sql);
}
}
function getComments($conn) {
$sql = "SELECT * FROM environments";
$result = mysqli_query($conn, $sql);
while($row = $result->fetch_assoc() ) {
echo "<div><p>";
echo $row['uid']."<br>";
echo $row['date']."<br>";
echo nl2br($row['message']);
echo "</p>
<form method = 'POST' action='editcomments.php'>
<input type = 'hidden' name = 'cid' value = '
".$row['cid']."'>
<input type = 'hidden' name = 'uid' value =
'".$row['uid']."'>
<input type = 'hidden' name = 'date' value =
'".$row['date']."'>
<input type = 'hidden' name = 'message' value =
'".$row['message']."'>
<button>Edit</button>
</form>
<div>";
}
}editcomments.php:
<?php
date_default_timezone_set("America/New_York");
include'dbh.inc.php';
include'environment.inc.php';
?>

<?php

$uid = $_POST['uid'];
$date = $_POST['date'];
$message = $_POST['message'];
echo "<form method = 'POST' action = '".editComments($conn)."'>
