I have a formA that posts and saves to the MYSQL DB
<form name="A" id="FormA" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post"> <== first visable form ,Submitting the data into DB
........field inputs. .....
<input type="submit" class="btn btn-primary" value="Submit">
</form>
I have a hidden form called PayForm that store some var with hidden input method and get the $input_amount as amount from FromA
It is noted that I haven't made the submit button .
This form is going to post to the EPayment Gateway .
<form name="payForm" id="payForm" method="post" action=" https://test.paydollar.com/b2cDemo/eng/payment/payForm.jsp">
<input type="hidden" id="merchantId" value="sth">
<input type="hidden" id="amount" value="<?php echo $input_amount; ?>" >
<input type="hidden" id="orderRef" value="<?php date_default_timezone_set("Asia/Taipei"); $date = date('m/d/Y h:i:s a', time()); echo $date ; ?>">
<input type="hidden" id="currCode" value="sth" >
<input type="hidden" id="mpsMode" value="sth" >
<input type="hidden" id="successUrl" value="http://www.yourdomain.com/Success.html">
<input type="hidden" id="failUrl" value="http://www.yourdomain.com/Fail.html">
<input type="hidden" id="cancelUrl" value="http://www.yourdomain.com/Cancel.html">
...
</form>
Here is my idea workflow :
1)User press "Submit" button in FormA ==> info in FormA is going to store into DB .
2)JS is running . Force the PayForm to post automatically . Then, The user is directed to the Payment Gateway .
In short , the
Submitbutton inFormAtrigger both forms post actions .
Here is my JS
<script type='text/javascript'>
var payFormDone = false;
$('#FormA').on('submit', function(e){
if( !payFormDone ) {
e.preventDefault(); // THIS WILL TRIGGER THE NEXT CODE
$('#payForm').submit();
}
});
$("#payForm").submit(function(event) {
/* stop form from submitting normally */
//event.preventDefault();
/* get the action attribute from the <form action=""> element */
var $form = $(this),
url = $form.attr( 'action' );
/* Send the data using post with element id name and name2*/
var posting = $.post( url, {
merchantId: $('#merchantId').val(),
amount: $('#amount').val(),
orderRef: $('#orderRef').val(),
currCode: $('#currCode').val(),
mpsMode: $('#mpsMode').val(),
successUrl: $('#successUrl').val(),
failUrl: $('#failUrl').val(),
cancelUrl: $('#cancelUrl').val(),
payType: $('#payType').val(),
lang: $('#lang').val(),
payMethod: $('#payMethod').val(),
secureHash: $('#secureHash').val()
} );
/* Alerts the results */
posting.done(function( data ) {
alert('success');
payFormDone = true;
$('#FormA').submit();
});
});
</script>
Now ,the idea is not working . It can only trigger second form action . The first form action is not triggered .At least ,the data in
FormAhas not saved to the DB .
posting.done(function( data ) {
alert('success');
payFormDone = true;
$('#payFormCcard').submit();
});
Is not working .I think !
This is how I post FormA to the server
<?php
// Include config file
require_once 'database.php';
header("Content-Type:text/html; charset=big5");
print_r($_POST);
// Define variables and initialize with empty values
$CName = $Address = $Phone = $amount= $Purpose= $Ticket = "";
$CName_err = $Address_err = $Phone_err = $amount_err = $Purpose_err = $Ticket_err="";
// Processing form data when form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
// Validate name
$input_CName = trim($_POST["CName"]);
if (empty($input_CName)) {
$CName_err = "Please enter a name.";
} elseif (!filter_var(trim($_POST["CName"]), FILTER_VALIDATE_REGEXP, array("options" => array("regexp" => "/^[a-zA-Z'-.\s ]+$/")))) {
$CName_err = 'Please enter a valid name.';
} else {
$CName = $input_CName;
}
......
if (empty($CName_err) && empty($Address_err) && empty($amount_err) && empty($Phone_err)) {
// Prepare an insert statement
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "INSERT INTO donation (CName, Address, Phone, Amount ,Ticket, Purpose) VALUES (?, ?, ?, ? ,?, ?)";
$q = $pdo->prepare($sql);
$q->execute(array($CName, $Address, $Phone, $amount ,$Ticket ,$Purpose));
Database::disconnect();
}
}
?>
you should not comment event.preventDefault(); from the second form. Currently what happens is it submitting it as default action which is post to url.
The submit handler for FormA actually prevents the submission of the form. That's why data is not saved to db.
$('#FormA').on('submit', function(e){
if( !payFormDone ) {
e.preventDefault(); // => HERE you are preventing the form from submitting
$('#payForm').submit();
}
});
Here you are in the submit handler for the form, but the call to preventDefault stops the submit for FormA and instead triggers the submit of payForm. See https://developer.mozilla.org/en-US/docs/Web/API/Event/preventDefault
Also instead of having that you trigger via javascript I'd probably send the first one normally. Then as response of the POST in the first form You might print a message to the user with something like: "You are being redirected to the payment gateway.. " and an hidden form with all the fields that is triggered automatically after x seconds. IMHO this approach is easier and more reliable.
So in the first html page I'll remove all your javascript code and leave only:
<form name="A" id="FormA" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post">
........field inputs. .....
<input type="submit" class="btn btn-primary" value="Submit">
</form>
When the user clicks on the button he submits the data to the php page in POST. On the server the data is saved to DB and the server prints a message to the user and redirect to the payment gateway (via javascript this time). Something like:
<?php if ($_SERVER['REQUEST_METHOD'] === 'POST') {
.... save data to db
?>
<form name="payForm" id="payForm" method="post" action=" https://test.paydollar.com/b2cDemo/eng/payment/payForm.jsp">
<input type="hidden" id="merchantId" value="sth">
<input type="hidden" id="amount" value="<?php echo $input_amount; ?>" >
<input type="hidden" id="orderRef" value="<?php date_default_timezone_set("Asia/Taipei"); $date = date('m/d/Y h:i:s a', time()); echo $date ; ?>">
<input type="hidden" id="currCode" value="sth" >
<input type="hidden" id="mpsMode" value="sth" >
<input type="hidden" id="successUrl" value="http://www.yourdomain.com/Success.html">
<input type="hidden" id="failUrl" value="http://www.yourdomain.com/Fail.html">
<input type="hidden" id="cancelUrl" value="http://www.yourdomain.com/Cancel.html">
<p>You are being redirected to the payment gateway. If the redirect takes too long</p>
<input type="submit" value"click here">
</form>
<script>
// submits the form after 5 seconds
setTimeout(function(){ $('#payForm').submit(); }, 5000);
</script>
<?php } // this ends the POST block ?>
Inside posting.done() please remove/detach the onSubmit handler for FormA just before calling the $('#FormA').submit();
posting.done(function( data ) {
alert('success');
$('#FormA').off('submit');
$('#FormA').submit();
});
Okay, why not send the formA fields with AJAX inside its onSubmit handler and submit formB from the posting.done() handler ?
<script type='text/javascript'>
$('#formA').on('submit', function(e){
e.preventDefault();
/* Send the data using post with element id name and name2*/
var posting = $.post( "<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>", {
field1: $('#field1').val(),
.....
} );
/* Alerts the results */
posting.done(function( data ) {
alert('success');
$('#FormB').submit();
}
});
</script>
If I correctly understand the question:
<script type='text/javascript'>
$('#FormA').on('submit', function(e){
e.preventDefault();
$('input[type="submit"]', $(this)).attr('disabled','disabled');
$.post( $(this).attr('action'), $(this).serialize(), function() {
var $payForm = $("#payForm");
$.post( $payForm.attr('action'), $payForm.serialize(), function(data) {
alert('success');
// redirect to whereever you want
});
});
});
</script>
UPDATE:
case 2) redirecting to payment gateway:
<script type='text/javascript'>
$("#payForm").submit(function(e) {
alert('redirecting to payment gateway');
});
$('#FormA').on('submit', function(e){
e.preventDefault();
$('input[type="submit"]', $(this)).attr('disabled','disabled');
$.post( $(this).attr('action'), $(this).serialize(), function() {
$("#payForm").submit();
});
});
</script>
NOTE: replace all your script with just this one, and check in browser if requests are made in the data posted - F12 (Developer tools) - Network tab. Keep in mind that this code is written on a scratch so it may have some errors, but it shows the way.
