</form>
Php code in "placebet.php"
I'm not sure if the code below is correct but I need it to show the input data from the form and give me a option to confirm the data(button) and then it can finally add to the database
<?php
/* Attempt MySQL server connection. Assuming you are running MySQL
server with default setting (user 'root' with no password) */
$link = mysqli_connect("localhost", "root", "", "forms");
$dba = mysqli_connect("localhost","root","","login");
// Check connection
if($link === false){
die("ERROR: Could not connect. " . mysqli_connect_error());
}
$error = false; //set the error status value
$error_msg = "";
$back = mysqli_real_escape_string($link, $_REQUEST['kickoff'][0]);
$total = count($back); // get the length of the match
for($i=0;$i<$total;$i++){
// Escape user inputs for security
$kickoff = mysqli_real_escape_string($link, $_REQUEST['kickoff'][$i]);
$match = mysqli_real_escape_string($link, $_REQUEST['match'][$i]);
$selection = mysqli_real_escape_string($link, $_REQUEST['result'][$i]);
$odd = mysqli_real_escape_string($link, $_REQUEST['value'][$i]);
$account = mysqli_real_escape_string($link, $_REQUEST['account'][0]);
$stake = mysqli_real_escape_string($link, $_REQUEST['stake'][0]);
$payout = mysqli_real_escape_string($link, $_REQUEST['payout'][0]);
$todds = mysqli_real_escape_string($link, $_REQUEST['todds'][0]);
$accabal = mysqli_real_escape_string($link, $_REQUEST['balance'][0]);
//run sql query for every iteration
$charge = mysqli_query($dba, "UPDATE users SET balance = $accabal- $stake WHERE username='".$_SESSION['username']."'") ;
$_SESSION["balance"] = $accabal- $stake ;
$date = date ('Ymd');
$create = mysqli_query($link,"CREATE TABLE R$date LIKE receipts") ;
$insert = mysqli_query($link,"INSERT INTO `R$date`(`Match`, `Selection`, `Odd`,`Account`,`Stake Amount`,`Payout`,`Total Odds`) VALUES ('$match','$selection','$odd','$account','$stake','$payout','$todds')");
if(!$insert)
{
$error = true;
$error_msg = $error_msg.mysqli_error($link);
}
//check your error status variable and show your output msg accordingly.
if($error){
echo "Error :".$error_msg;
}else{
header("location: index.php");
exit;
}
}
mysqli_close($db);
?>

What you want to do isn't redirect to index.php, cause with this you start a new request and cant point on the request data of placebet.php anymore.
You want either to send your form via javascript ajax request and then react to the response of placebet.php (https://www.w3schools.com/js/js_ajax_intro.asp) or generating your own new output at placebet.php which then can be a confirm page or something similar.
e.g.
if($error){
echo "Error :".$error_msg;
}else{
echo "Data has been stored!";
}
You also could put your html at the end of the php file after closing the php part with ?> like mentioned here https://www.thoughtco.com/php-with-html-2693952#:~:text=As%20you%20can%20see%2C%20you,re%20inside%20the%20PHP%20tags).
