How to deny payment via PayPal IPN?

由 你说的曾经没有我的故事 提交于 2019-12-25 09:44:00
问题 I need to create dynamic 'Pay Now' buttons on my site, and PayPal says the way to do this is via an HTML FORM with preset variables for the price, currency, and item of the purchase. I use PayPal IPN to notify me when a payment has complete. However, what's to stop someone from modifying the query parameters of the Pay Now button to change the price? Some people have told me to redirect the button through a PHP file that sends you to a PayPal payment page with the parameters in place, but the

Closing HTML Tags Automatically

由 前提是你 提交于 2019-12-25 04:14:48
问题 I've allowed users to use <pre></pre> tags to display code in comments and articles, but I've come across a problem that I'm struggling to solve. When a user fails to close an HTML tag, for example: <pre> <html> <head> </head> </pre> the comment appears to be blank. What I'm looking for is some sort of function that will automatically close any HTML tags that the user missed. Thanks in advance. 回答1: Well it's going to get nasty if you dont use a framework but your courage is admired.

Age Check and jquery

由 爱⌒轻易说出口 提交于 2019-12-25 03:41:02
问题 Does anyone have any solid examples of how to implement a jQuery or javascript based age checker? I'm looking to send someone to a page where they need to enter in the Day, Month and Year at least once a day when they hit any page on the site. Once they validate as 18 then they would not be pestered again until the next day if they return. Any ideas? 回答1: A cookie-based solution does seem a logical fit since you can programmatically modify them from JavaScript and you can set their expiry.

Add integers safely, and prove the safety

由 安稳与你 提交于 2019-12-23 16:24:17
问题 Programming course assignment asks to write a (safe) function that adds two integers, and show that the function is safe. The following code represents my solution. I am not an expert on the C standard (or on formal verification methods). So I would like to ask: Are there better (or different) solutions? Thank you #include <limits.h> /* Try to add integers op1 and op2. Return 0 (success) or 1 (overflow prevented). In case of success, write the sum to res. */ int safe_int_add(int * res, int

SSL Certificate Verification programmatically

由 五迷三道 提交于 2019-12-23 04:47:07
问题 I know this will be a huge post, but I wanted to present a problem that I am facing by essentially giving all the details of it. Background I have an application which triggers firefox to fetch URL data and present the individual component load time of all components in a web page (like Firebug). However the application does not validate ssl certs automatically (i.e it gets stuck up if there is a bad certificate as there is no user to manually accept/reject a certificate and it is all done

Only allow 'business' email address register on website

由 此生再无相见时 提交于 2019-12-21 07:57:15
问题 We are looking to build a new website that is specifically for commercial/business use. We need to only allow 'business' email addresses register. So users with Gmail, Hotmail, Yahoo etc cannot apply with those email addresses. Is there a way to do this, other than creating a blacklist of domains such as gmail.com, hotmail.com etc? It will be an international site - so it will be impossible to blacklist all of the public email providers. Thanks Ian 回答1: As others have stated, it doesn't
