quick-paypal-payments/quick-paypal-payments/legacy/quick-paypal-payments.phpQuick Paypal Payments [test] Shortcode
The Quick-PayPal-Payments shortcode is a function that triggers a specific action. It uses the ‘add_shortcode’ function to register a new shortcode ‘test’. This shortcode calls the ‘build_shortcode’ function. It creates a new instance of the User_Template_Loader class and sets template data. The ‘ob_start’ function is used to turn on output buffering. The ‘get_template_part’ method is then used to load a specific template part ‘test’. The ‘ob_get_clean’ function is used to get the current buffer contents and delete the output buffer, storing the HTML content. Finally, the HTML content is returned when the shortcode is used.
Shortcode: [test]
Examples and Usage
Basic example – A simple usage of the shortcode to display a predefined message.
[test]Advanced examples
Using the shortcode to display a custom message by passing it as a parameter.
[test message="This is a custom message"]Using the shortcode to display a message and also pass an additional parameter ‘color’ to change the color of the message.
