This will only work if returnurl is also set. This variable is often required by membership type software 0 – all shopping cart transactions use the GET method 1 – the payer’s browser is redirected to the return URL by the GET method, and no transaction variables are sent 2 – the payer’s browser is redirected to the return URL by the POST method, and all transaction variables are also posted The default is 0. notifyurl = The URL to send payment advice too. Often required for IPN or other notifications If this parameter is not used, no notifyurl value is added to the button returnurl = The URL to which the payer’s browser is redirected after completing the payment; for example, a URL on your site that displays a “Thank you for your payment” page. Default – The browser is redirected to a PayPal web page. cancelurl = The URL to which the payer’s browser is redirected if the purchaser cancels the payment transaction before completing the process scriptcode = the link to any script code that you may need to include. e.g For Jrox JAM, some script code is added to the paypal buttons.

Allowable values: paypal – use the PayPal page style primary – use the page style that you marked as primary in your account profile page_style_name – use the custom payment page style from your account profile that has the specified name The default is primary if you added a custom payment page style to your account profile.

Subscription payments recur unless subscribers cancel their subscriptions before the end of the current billing cycle or you limit the number of times that payments recur with the value that you specify for srt. Allowable values: 0 – subscription payments do not recur 1 – subscription payments recur The default is 0. srt = Recurring times. Number of times that subscription payments recur. Specify an integer above 1. Valid only if you specify src="1". Allowable values:an integer above 1. sra = Reattempt on failure.

tag. The formatting options available are: divwidth = the width of the div. This should be at least the width of the image. Default - 100% textalign = the alignment of the image / text within the div Allowable values: left - text is left justified right - text is right justified center - text is centered No default, taken from page format float = position of the div on the page left - the div 'floats' on the left right - the div 'floats' on the right Default - if this value is missing, the div is centered on the page marginleft = the amount of space between the div and the text to the left of the div (particularly good to use when using float=right) Default - if this value is missing, the page format is used marginright = the amount of space between the div and the text to the right of the div (particularly good to use when using float=left) Default - if this value is missing, the page format is used margintop = the amount of space to the line above the div Default = 10px; marginbottom = the amount of space to the line below the div Default = 10px; Button Formatting: Image Classes: The shortcode will add a 'placeholder' Paypal image that is 1px wide by 1px tall into the button. The code adds a class of "ppalholder" to this image. This will allow site owners to add the class to their theme styles and remove any borders that cause the image to be 'visible'. Class added to Buy Now, Add To Cart, Hosted or Subscribe button The code will add the class "ppalbtn" to the actual image embedded on the page to allow for more formatting choices.
