Hello guys! I am trying to insert data to the database and after sending the data using form the URL which I am using POST method will be something like this " somelinks/add-result.php?"
What's going on with it, any idea?

What I have tried:

this is the page for inserting data to the database, and I am using form action as insert.php and method is POST.
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "result1";
$con= mysqli_connect('localhost','root','','$dbname');

echo'Not connected to server';
echo 'data base not selected';
$name =$_GET['Name'];
$id =$_GET['id'];
$Class =$_GET['Class'];
$Law =$_GET['Law'];
$Hoqoq =$_GET['Hoqoq'];
$PanelCode =$_GET['Law panel'];

$sql="INSERT INTO result (Name,id,Class,Hoqoq,Law,Law panel)VALUES('$name','$id','$Class','$Hoqoq','$Law','$PanelCode')";
echo'Not Inserted';
header("refresh:2; url=admin-panel.php");

Your code is vulnerable to SQL Injection[^]. NEVER use string concatenation / interpolation to build a SQL query. ALWAYS use a parameterized query.

its hard to digest those things written in manual but I will have a research on it, Thanks Richard! <3

do you think this one is fine ?

connect_error) {
die("Connection failed: " . $conn->connect_error);

// prepare and bind
$stmt = $conn->prepare("INSERT INTO MyGuests (firstname, lastname, email) VALUES (?, ?, ?)");
$stmt->bind_param("sss", $firstname, $lastname, $email);

// set parameters and execute
$firstname = "John";
$lastname = "Doe";
$email = "";

$firstname = "Mary";
$lastname = "Moe";
$email = "";

$firstname = "Julie";
$lastname = "Dooley";
$email = "";

echo "New records created successfully";

That looks much better. :)

then how do I take the data from HTML form and send it to data base ?
Richard Deeming 6-Oct-20 3:19am
Using the $_GET or $_POST collections. Just store them in the variables you've bound to the parameters.
$stmt->bind_param("sss", $firstname, $lastname, $email);
$firstname = $_GET['FirstName'];

Rechard I am getting form values in URL and they are not being sent to the database. Name=rashed&id=10&class=10&submit=
Richard Deeming 7-Oct-20 6:34am
Your query-string values don't match the values you're trying to extract.

$firstname = $_GET['FirstName'];

There is no FirstName parameter in your query-string.

thanks Richard! ^_^ its working now, now I am having trouble with updating the table -_-.

Your issue is not clear. You are usign query string and not able to get data?
Afg Hunter 5-Oct-20 12:12pm
yea, the data is not storing in website's Database.
Sandeep Mewara 5-Oct-20 14:38pm
Above code you share looks all static. Is there a problem with it?

Further, I was asking how are you passign data - using a query param or using header or body?
Afg Hunter 6-Oct-20 3:12am
I was using POST method to send the data as u can see that in codes,but I was getting a question mark after the URL and the data was not getting stored in database.

The data sent in a POST request is in the $_POST array. See PHP: $_POST - Manual[^]
Adding to Sandeep's answer, above, there's a third option:

$_REQUEST works for both $_PUT and $_GET data. There's a possible catch: if you post both types of data to the same page AND they both use the same id then you will have a clash in not being able to get them both. HOWEVER - I've never done both, together, and certainly wouldn't reuse the name for the index, anyway. It's never been a problem in about ten years.

You say that you POST the data but in your code above you are retrieving a using GET.
$name =$_GET['Name'];
$id =$_GET['id'];
$Class =$_GET['Class'];
$Law =$_GET['Law'];
$Hoqoq =$_GET['Hoqoq'];
$PanelCode =$_GET['Law panel'];

Read about them: POST (works with headers) vs GET (it works with query strings - data after ? in url): PHP - GET & POST Methods - Tutorialspoint[^]

Assuming you made a right POST call, following is the way to retrieve data:
    $id =$_POST['id'];
    $Class =$_POST['Class'];
    $Law =$_POST['Law'];
    $Hoqoq =$_POST['Hoqoq'];
    $PanelCode =$_POST['Law panel'];
    $sql =...

As R.Deeming shared, make sure to have parameterized query to avoid SQL Injection.
