If you are using an AMP-compatible theme and using the AMP plugin for AMP implementation, then sometimes you may need to check if the current page is an AMP page request or a normal page request.

AMP plugin has a built-in function that you can use to do just that. Its amp_is_request(). This function allows you to check whether the current page is an AMP request or a normal request. I have listed a few examples below with the implementation of amp_is_rquest() to achieve a few features.

Load a different sidebar for AMP pages

You may want to load a different sidebar specifically for AMP pages so that it will have complete AMP-compatible code. Here is an example how you can achieve that :

Create a custom function to check if the current AMP request that avoids errors when the AMP plugin is disabled. Add the following code in the functions.php file to do that.

// Add this function in functions.php file
// custom function to check if amp_is_request exists so that the site doesn't throw error when AMP plugin is disabled.
function wptips_is_amp() {
  if ( function_exists( 'amp_is_request' ) ):
    return amp_is_request();
  else :
    return false;

Create a custom AMP sidebar and call the sidebar if it’s an AMP request using the newly defined custom function.

// Register custom AMP Sidebar ( add this code in functions.php file )
			'name'          => __( 'AMP Sidebar', 'wptips' ),
			'id'            => 'amp-sidebar',
			'description'   => __( 'Add widgets here to appear in AMP site sidebar.', 'wptips' ),
			'before_widget' => '<section id="%1$s" class="widget %2$s">',
			'after_widget'  => '</section>',
			'before_title'  => '<div class="widget-title">',
			'after_title'   => '</div>',

// Add this code in your sidebar.php or any other sidebar file where you want to implement custom sidebar for AMP version of the site.
if ( wpb_is_amp() ): dynamic_sidebar( 'amp-sidebar' );	else:	dynamic_sidebar( 'main-sidebar' ); endif;

Note: The function is_amp_endpoint() is deprecated, and you should switch to amp_is_rquest() if you are using the latest version of the AMP plugin.
