First off excellent work on this plugin. I rate it 5 stars for ease of use and functionality.
My question regards the 'thank you page'. Currently, the visitor is returned to the page where the shortcode is installed upon completion of the Paypal transaction, and works as designed with the field data from the dashboard.
What I want to do is instead of this, direct the visitor to a separate landing page elsewhere on the site. I suspect this can be achieved by modifying the code found on the "seamless-donations/dgx-donate-paypalstd.php" page of the plugin editor - specifically I'm referring to this code approximately halfway down the page:
$successUrl .= "thanks=1&sessionid=";
$successUrl .= "$sessionID";
Can you please provide insights as to how I can accomplish this?
Also, is there a way I can test this functionality without repeatedly making a donation?
