Question

我在订单页面上添加了一个操作按钮，问题是没有向该函数传递任何数据。

add_filter( 'woocommerce_admin_order_actions', 'add_customer_second_payment_reminder_button', 100, 2 );
function add_customer_second_payment_reminder_button( $actions, $order ) {
    if ( $order->has_status(array( 'partially-paid' ) )) {
        $actions['email_reminder'] = array(
            'url'       => wp_nonce_url( admin_url('admin-ajax.php?action=customer_second_payment_reminder_button&order_id=' . $order->get_id() )),
            'name'      => __( 'Email Second Payment Reminder' , 'woocommerce-deposits' ),
            'action'    => 'email_reminder',
        );
    }
    return $actions;
}
add_action( 'wp_ajax_customer_second_payment_reminder_button', 'customer_second_payment_reminder_button' );
function customer_second_payment_reminder_button( $order_id ) {
  do_action( 'woocommerce_deposits_second_payment_reminder_email' , $order_id );
}

add_action( 'admin_head', 'add_customer_second_payment_reminder_button_css' );
function add_customer_second_payment_reminder_button_css() {
    echo '<style>.wc-action-button-'.'email_reminder'.'::after { font-family: woocommerce !important; content: "\e030" !important; }</style>';
}

所以当我使用按钮时总是显示0。 customer_second_payment_reminder_button函数未从URL接收？order_id参数。我把一个var_dump（$ order_id）;在函数中并显示string（0）“” 0

如何将订单ID传递给函数？

您的代码中存在一些错误和遗漏的东西：

没有带有processing file: Right.Rmd |......... | 14% ordinary text without R code |................... | 29% label: setup (with options) List of 1 $ include: logi FALSE |............................ | 43% ordinary text without R code |..................................... | 57% label: cars |.............................................. | 71% ordinary text without R code |........................................................ | 86% label: pressure (with options) List of 1 $ echo: logi FALSE |.................................................................| 100% ordinary text without R code /Applications/RStudio.app/Contents/MacOS/pandoc/pandoc +RTS -K512m -RTS Right.utf8.md --to latex --from markdown+autolink_bare_uris+ascii_identifiers+tex_math_single_backslash --output Right.tex --template /Library/Frameworks/R.framework/Versions/3.5/Resources/library/rmarkdown/rmd/latex/default-1.17.0.2.tex --highlight-style tango --latex-engine pdflatex --variable graphics=yes --variable 'geometry:margin=1in' --variable 'compact-title:yes' output file: Right.knit.md tlmgr search --file --global '/framed.sty' tlmgr: Remote repository is newer than local (2018 < 2019) Cross release updates are only supported with update-tlmgr-latest(.sh/.exe) --update Please see https://tug.org/texlive/upgrade.html for details. !

订单ID是通过URL发送的，因此您可以通过wp_ajax_nopriv_{action}变量来捕获
您必须保护Ajax功能并在最后嵌入重定向。如果没有，您将获得白页。也永远不要忘记最后的$_GET ...

所以您的功能代码将是：

exit;

代码进入您的活动子主题（或活动主题）的functions.php文件中。经过测试并可以正常工作。
