Paypal Button with a custom price

Question

I have been give the task of making a PayPal button which will receive a value based on user choices, but there are so many options in the website that making a button for each choice is unreasonable, I have searched for the answer but either the information was outdated, insecure, or I didn't have the knowledge to understand.

I have seen terms of checkout API,..etc., this and that, but I can't just figure it out.

So, can you guys enlighten me and show me the way.

I know html, php but still kind of a beginner, js sort of.

Answer 1

You can use

document.write('variable') 

In JavaScript

Or

echo 'variable'

In PHP

To change the text of a button to be a certain variable that could depend on the item. JavaScript is easier to setup but PHP could work well if you have a server side data base of items and their prices.

Answer 2

Without knowing more about your problem, I'll outline an implementation of a product and quantity system that you can flick through.

You say you have a collection of items, x, y, x and provide the option to choose the length of time (in months) the user can have the product.

Let's say, in Javascript, you have the following class for a Product object:

function Product() = {
    this.Name = "Gaming Computer";
    this.Price = 100; // Per month, in $.
}

So a user selects a Product , and the Product the choose is the Gaming Computer . You can test see the name of the product in code by performing:

console.log(Product.Name) // Gaming Computer

You now have the product, and the associated property , price . From the inline comment you can see this is in $, per month .

Let's assume the user picks Gaming computer, 6 months . You don't want to do the following:

var month = $('#monthComboBox').val();
if(product.Name == "Gaming Computer" and month == 1) {
   // do stuff
} else if(product.Name == "Gaming Computer" and month == 2) {
// This is getting laborious
} else ....

so you would do the following:

Product.Price * month = totalCost , which will give you the total to be charged to the user. You can then pass this value to the Paypal button and charge it as needed.
