Question

I have spent the day studying up on jquery because I think it will allow me to do this. I have a paypal form and I want the “onClick” button to send this field to my sql table

<input type="hidden" name="amount" id="amount" value="0.05">

Meanwhile my PayPal button is doing this:

<input class="btn btn-primary" onClick="send()" type="submit" value="Subscribe">

How can I pass this value to my process_plan.php? So far I have this but it’s hanging and not working.

function send() {
    var id = $('#amount').val();
    var result;
    $.ajax({
        type: "POST",
        url: "process_plan.php",
        data: {
            "amount" : amount
        },
        async: true,
        dataType: "html",
        success: function(response) { 
            result = response;
        },
        error: function(response) {
            alert("Oh no! An error occured!");
        }
    });
    return result;
}

I apologize if the code is really wonky – really my first day studying up on Jquery and Ajax.

Don’t know if that is the problem, but I think you have a little mistake in your code.

Please try :
...
data: {
amount : "amount"
},
...

In case that amount is a var too, delete the “
