edit.php file code is as follows:
<?php
include("./config/conn.php");//The content is related to connecting to the database
$id = $ _GET['id'];
$pid = $_POST['pid'];
$name = $_POST['name'];
$dept = $_POST['dept'];
$phone = $_POST['phone'];
$tel = $_POST['tel'];
$time = date("Y-m-d H:i:s");
if( $conn){
$sql = "update txl set pid='$pid',name='$name',dept='$dept',phone='$phone',tel='$tel',cre_time ='$time' where id='$id'";
$que = mysqli_query($conn,$sql);
if($que){
echo "<script>alert(' The modification is successful and returns ');location.href='txl_list.php';</script>";
}else{
='txl_list.php';</script>";
}
}
?>
---------------- ------------------------------------------
The above code Medium:
$sql = "update txl set pid='$pid',name='$name',dept='$dept',phone='$phone',tel='$tel', cre_time='$time' where id='$id'";
The specific id value can be modified by directly specifying id='$id'". I don’t know why, but it feels like the id value is obtained. question

I found the problem. I used POST submission on the submission page <form action="edit.php" method="post">
The receiving page should also be in POST mode, put $id = $_GET['id']; Change to $id = $_POST['id']; That's it
You first output $_GET['id'] in the php file to see if you can get the value, or whether your parameter names are written correctly
