请求校验WooCommerce结算页面自定义消息代码的语法正确性

Hey there! Let's take a look at your WooCommerce checkout notice code. I spotted a couple of syntax and logic tweaks needed to make it fully compliant and work as intended:

Issues in the Original Code #

• You used sprintf() but didn't include any placeholders (like %s) in the first string, yet passed an extra parameter. This creates unnecessary redundancy and could trigger PHP warnings.
• The " HTML entities are unnecessary in PHP code—you should use regular single/double quotes instead for clarity.
• Your intended bold "Information:" prefix wasn't actually being inserted into the notice text correctly with the current structure.

Corrected Code (Best Practice Version) #

add_action( 'woocommerce_before_checkout_form', 'print_webcache_notice', 10 );

function print_webcache_notice() {
    wc_print_notice( 
        sprintf( 
            '<strong>%s</strong> %s',
            __( "Information:", "woocommerce" ),
            __( "Having trouble checking out? Please clear your web browser cache!", "woocommerce" )
        ), 
        'success' 
    );
}

What Changed? #

• Restructured sprintf() with %s placeholders to properly inject the bolded "Information:" prefix and main notice text. This keeps each translatable string separate, which follows WooCommerce's internationalization best practices.
• Replaced " with regular double quotes for cleaner, valid PHP syntax.
• Ensured both text segments are wrapped in __() so they can be localized if needed.

Simplified Alternative (No sprintf()) #

If you prefer a more straightforward string concatenation approach, this also works perfectly:

add_action( 'woocommerce_before_checkout_form', 'print_webcache_notice', 10 );

function print_webcache_notice() {
    wc_print_notice( 
        '<strong>' . __( "Information:", "woocommerce" ) . '</strong> ' . __( "Having trouble checking out? Please clear your web browser cache!", "woocommerce" ),
        'success' 
    );
}

Both versions are fully syntax-compliant, will display your notice correctly on the checkout page, and align with WooCommerce coding standards.
