Check where a redirect came

Hi all

I set up a site that uses PayPal as payment gateway.  When the user renews their subscription, I wish their account automatically update with the new end date of subscription.  I can get this code very well, but I have a problem.

The problem is, and that's understandable, PayPal said for security reasons, I can't it for my site, their will talk to each other.  Thus, when PayPal redirects the user to my site, is there a way to check that the page was actually redirected to PayPal and just typed in the address bar?  I don't want to have to do all the updates manually, but I also don't want them to just type the url of the page of "thank you" in the address bar and update their account without having to pay.  Is there a way to do this?  Thank you.

You need PayPal IPN to do what you want. More information available from the URL I provided. Note there is no charge to US for PayPal IPN.

How it works

Merchants create an IPN listener on their Web site page and then specify the URL of the page of the listener in their PayPal account profile. PayPal then sends notifications of all events related to the transaction at this URL. When customers pay for goods or services, PayPal sends a FORM POST secure containing payment information (IPN messages) to the URL. The IPN listener detects and processes messages IPN using process merchant backend. The receiver IPN page contains a custom script or program that expects the messages, validates with PayPal and then switches to various back-end for processing applications.

  • State of session/Dom to the point where to redirect to the page of this application

    Hello

    I joined 3 OpenLayers in page 5 of the APEX. When I select an object on the map I want to show a modal page with related data. For this, I do the following:

    1. I put the value of an element in the DOM JavaScript: $s ('P1_SELECTED_ID', $v ('P1_ID'));
    2. I update the value of the session of the item likechubby Kiran described here: assigning the value dot PAGE APEX
    3. I click on a button to redirect to modal page where I put the value: P2_EMPNO with the value of & P1_ID.
    4. The modal page opens, but no value will be defined. (the same when I set the page as usual mode)

    I tested it also on apex.oracle.com - but with the same result:

    Workspace: lets

    User: guest

    Pass: Lets1234

    Application: SessionUpdate

    Link: https://apex.oracle.com/pls/apex/f?p=11045

    I also read this post: APEX point: elements of the Page to send

    I checked the State of the DOM element - with Firebug and session state with the tools of the developer toolbar everything works fine...

    Can someone help with this problem?

  • I put my setting to alert me when page wants to redirect and I also checked for a "redirection virus" (doen't find one) and I STILL get redirects

    I bought a laptop computer used in a computer repair store pretty good reputation (a very high ratings online) and this computer is a Windows operating system 7/8.

    I immediately noticed that I had a problem of redirection. It took me some time to try to solve this problem (other than my anti-malware software) and recently I discovered how to go into my settings and set up the "warn before redirection. It works in some cases, but I'm always redirected in MANY occasions, but not always on the same pages/sites.

    I checked all my modules and do not know which could be bad. I have Adobe modules but I always downloadthose and update those directly from the Adobe House.

    Does anyone have any OTHER suggestions to stop those annoying redirects?

    jscher2000,

    Windows Defender went to work one day this last week and found a Trojan that my anti virus and malware did not pick up. I had not had the time to do what you suggested, yet (as I am a truck driver and do not have a lot of time online) and I was pleasantly surprised when the windows Defender picked it up. I have more problems with the redirection.

    Thanks a lot for your help

    At that time, the pre doesn't have a function of zoom of the camera or VCR. If this could be added as a software update, you can request this option to www.palm.com/feedback where our developers monitor applications for clients for changes and updates.
