Page Guard uses a single URL parameter or POST variable as a means of providing a token to guard access to any page on which this plugin’s shortcode is placed. Output of alternative content can be made to occur when the token is missing or fails to match what is expected – if the token received matches the expected one, the controlled content can be revealed to the visitor.
The shortcode to use is ‘pageguard’ – its attributes are:
tokenparam (required) -> a string value containing the name of the token URL param - e.g. 'mytoken' eq (optional) -> a string value containing the expected value of the tokenparam - e.g. 'x34ggj45b' ne (optional) -> as for "eq" but when used, shortcode will output content on non matching token absent (optional) -> when absent="1", shortcode will output content on detection of missing token title (optional) -> a string containing a page title to apply when the parent shortcode's criteria are met
show block on matching token - [pageguard param="token" eq="download"] Text to be output on matching token found [/pageguard] show block on non match + change title [pageguard tokenparam="token" ne="download" title="Downloads - invalid token"] Error text for output when token fails to match [/pageguard] show this on no token found + change title [pageguard tokenparam="token" absent="1" title="Downloads - missing token"] Error text for output when token is missing [/pageguard]
Add a parameter to the end of the return URL (using any name and value you want) when you set up your button in PayPal e.g.
Next, add pageguard short codes for the cases you intend to handle to your return page in WordPress –
[pageguard param="token" eq="x34ggj45b" title="Title for matched token"] Text to be output on matching token found [/pageguard] [pageguard tokenparam="token" ne="x34ggj45b" title="Title for failed match"] Error text for output when token fails to match [/pageguard] [pageguard tokenparam="token" absent="1" title="Title for missing token"] Error text for output when token is missing [/pageguard]
This will correctly display the main content for the page when Page Guard detects a matching token. It also provides for the possibility of providing different error content for the page in the event of the token being incorrect or missing.
