如何在 PayPal JavaScript 中传递 PHP 变量作为支付金额

Question

所以我有这个应用程序，我正在尝试实施 [PayPal Express][1]

[1]: https://developer.paypal.com/demo/checkout/#/pattern/client 但我的问题是我无法选择从 php 到 javascript 'value'

的价格变量

我试过了value: '<?php echo $order_amount;?>' 无济于事。

这是贝宝 JS：

<script>
    // Render the PayPal button into #paypal-button-container
    paypal.Buttons({

        // Set up the transaction
        createOrder: function(data, actions) {
            return actions.order.create({
                purchase_units: [{
                    amount: {
                        value: '88.44'
                    }
                }]
            });
        },

        // Finalize the transaction
        onApprove: function(data, actions) {
            return actions.order.capture().then(function(orderData) {
                // Successful capture! For demo purposes:
                console.log('Capture result', orderData, JSON.stringify(orderData, null, 2));
                var transaction = orderData.purchase_units[0].payments.captures[0];
                alert('Transaction '+ transaction.status + ': ' + transaction.id + '\n\nSee console for all available details');

                // Replace the above to show a success message within this page, e.g.
                // const element = document.getElementById('paypal-button-container');
                // element.innerHTML = '';
                // element.innerHTML = '<h3>Thank you for your payment!</h3>';
                // Or go to another URL:  actions.redirect('thank_you.html');
            });
        }


    }).render('#paypal-button-container');
</script>

如何在 js 中将此 $order_amount 称为 value 以便我可以处理付款？

Answer 1

感谢@David 的指导，我能够解决我的问题。

我未能在 PayPal 的 js 上定义值 id。

我在顶部创建了一个隐藏的输入字段，其 ID 如下所示：

<input type="hidden" id="t_amount" value="<?php echo $orders['order_amount']; ?>">

这是我添加的：

 var amountt= document.getElementById("t_amount").value; 
        console.log(amountt);

然后我将 amountt 作为值，它就像魅力一样工作。

这是我的全部代码：

<script>
        var amountt= document.getElementById("t_amount").value; 
        console.log(amountt);
    // Render the PayPal button into #paypal-button-container
    paypal.Buttons({

        // Set up the transaction
        createOrder: function(data, actions) {
            return actions.order.create({
                purchase_units: [{
                    
                    amount: {
                        value: amountt
                    }
                }]
            });
        },

        // Finalize the transaction
        onApprove: function(data, actions) {
            return actions.order.capture().then(function(orderData) {
                // Successful capture! For demo purposes:
                console.log('Capture result', orderData, JSON.stringify(orderData, null, 2));
                var transaction = orderData.purchase_units[0].payments.captures[0];
                alert('Transaction '+ transaction.status + ': ' + transaction.id + '\n\nSee console for all available details');

                // Replace the above to show a success message within this page, e.g.
                // const element = document.getElementById('paypal-button-container');
                // element.innerHTML = '';
                // element.innerHTML = '<h3>Thank you for your payment!</h3>';
                // Or go to another URL:  actions.redirect('thank_you.html');
            });
        }


    }).render('#paypal-button-container');
</script>
