php - Submit Multiple Forms With One Button

Question

I am using $_SESSION to dynamically create forms for my web store. These forms hold the custom info for the product that the customer wants. This is the layout:

Page1

Customer fills out form that looks something like this:

<form action="page2" method="post">
<input type="text" name="size">
<input type="text" name="color">
<input type="submit" name="submit" value="Review Order">
</form>

Page2

Customer reviews order details and has the option of adding more products. Customer goes back to page1 to order another one. All of the customer's orders will show on page2 in their respective form.

Looks like this:

Size: 1
Color: blue
Click Here To Checkout

Size: 2
Color:green
Click Here To Checkout

Size:3
color:red
Click Here To Checkout

What I want is one button that will add ALL orders to the PayPal cart. Sure they can add every order individually by clicking on Click Here To Checkout, but then they will have to go through a big loop to add multiple products.

I want the customer to be able to add as many products as possible and then click one button that adds all of the orders to the shopping cart.

This is what I tried but it obviously didn't work:

<script>
$(document).ready(function(){
$('#clickAll').on('click', function() {
    $('input[type="submit"]').trigger('click');
    });
    });
    </script>

    <form action="" method="post">
    <input type="text" name="name">
    <input type="submit" name="submit" value="submit">
    </form>

    <form action="" method="post">
    <input type="text" name="name">
    <input type="submit" name="submit" value="submit">
    </form>

    <form action="" method="post">
    <input type="text" name="name">
    <input type="submit" name="submit" value="submit">
    </form>

    <button id="clickAll">Submit All</button>

Here is the php script that generates the dynamic forms using $_SESSION:

<?php

if(isset($_POST['submit'])) :

$test = array(
    'size' => $_POST['size'],
    'color' => $_POST['color'],
    'submit' => $_POST['submit']
);

$_SESSION['testing'][] = $test;

endif;


if(isset($_SESSION['testing'])) : 

foreach($_SESSION['testing'] as $sav) {

?>

<form action="paypal.com/..." method="post">
<input type="text" name="size" value="<?php echo $sav['size']; ?>">
<input type="text" name="color" value="<?php echo $sav['color']; ?>">
<input type="submit" name="submit" value="Click Here to Checkout">
</form>

<?php } endif; ?>

So the question is, how can I submit all of the forms with ONE button?

Answer 1

Have you tried to do it with $.ajax? You can add an foreach, or call another form on the Onsucces function. Another approach is changing all to one form with an array that points to the right "abstract" form:

<form action="" method="post">
    <input type="text" name="name[]">
    <input type="text" name="example[]">

    <input type="text" name="name[]">
    <input type="text" name="example[]">

    <input type="text" name="name[]">
    <input type="text" name="example[]">

    <button id="clickAll">Submit All</button>
</form>

And in php:

foreach ($_POST['name'] as $key => $value) {
    $_POST['name'][$key]; // make something with it
    $_POST['example'][$key];  // it will get the same index $key
}
