paypal - How to know the URL referrer in PHP? -

-
I'm new to integrating PayPal with sites, so easily from the service I can use Can the available method be? What am I trying to do, when the user clicks on "Return to my website", I want my return URL to know that the referrer is PayPal so I can send it automatically to the homepage . how to do this? I tried $ _ SERVER ['HTTP_REFERER'] but it does not seem like anything. During the IPN conversation I set the cookie and session (though I am not sure whether I am correcting it or doing this right), but on returning to my website, it does not seem to recognize any session . If I use it by using $ _ SERVER ['HTTP_REFERER'] , then I'm afraid it's a security risk, is not it? If so, is there any other way I remember? help please. Should you really know the referrer?

-
Is there a way to format XAM generated when a flow document is saved? Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...
