I am trying to implement and update query that updates a record in the database. I'm new to php here is my code :
<input type="text" name="name" value="<?= $name ?> "><br><br>
E-mail: <input type="text" name="email" value="<?= $email ?>" ><br><br>
Password: <input type="password" name="password" value="<?= $pass ?>" >
Here is the fetch command:

$id = $_GET['id'];
$qry = "SELECT * from studentinformation WHERE ID = $id";
$result = mysqli_query($con,$qry) or die(mysqli_error($con));
while($row = mysqli_fetch_assoc($result)){
$name= $row['FullName'];
$email = $row['email'];
$pass = $row['Password'];
$major = $row['major'];
}
?>

<?php
include("connection.php");
//include("UpdateStudent.php");
$id = $_GET['id'];
$name = $_GET['name'];
$email= $GET['email'];
$pass = $_GET['password'];
//$major = $_POST['major'];
$qry = "UPDATE studentinformation SET FullName = '$name', email='$email', Password= '$pass'
WHERE ID = $id";
$result = mysqli_query($con,$qry) or die(mysqli_error($con));
if($result === false){
echo "Record didn't update";

echo "Record Updated";
}
?>
Here is the form:
<form action="UpdateStudentAction.php?id=<?= $id ?>" method="get" enctype="multipart/form-data">
Please help guys I'm new to php

Answer 1

Move id from action attribute into a hidden input:
<form action="UpdateStudentAction.php" method="get" enctype="multipart/form-data">
<input type="hidden" name="id" value="<?=$id?>">
...
will do the magic.
And avoid empty spaces into value attributes;

Answer 2

Make your form POST data instead of using GET method (that passes form data through url). Especially that you already using id query param in the url. You can include the id inside the form as a hidden field:
<form action="UpdateStudentAction.php?id=<?= $id ?>" method="POST" enctype="multipart/form-data">
<input type="hidden" name="id" value="<?= $id ?> ">
<input type="text" name="name" value="<?= $name ?> "><br><br>
E-mail: <input type="text" name="email" value="<?= $email ?>" ><br><br>
Password: <input type="password" name="password" value="<?= $pass ?>" >
</form>
Then in your UpdateStudentAction.php file you can receive data using post:
<?php
include("connection.php");
//include("UpdateStudent.php");
$id = $_POST['id'];
$name = $_POST['name'];
$email= $_POST['email'];
$pass = $_POST['password'];
//$major = $_POST['major'];
$qry = "UPDATE studentinformation SET FullName = '$name', email='$email', Password= '$pass'
WHERE ID = $id";
$result = mysqli_query($con,$qry) or die(mysqli_error($con));
if($result === false){
echo "Record didn't update";
}
else{
echo "Record Updated";
}
?>

Answer 3

The GET method is restricted to send upto 1024 characters only.
The POST method does not have any restriction on data size to be sent. (You can use POST method instead of GET method)
