Question

我在function.php上有一些代码，这些代码是我在前端通过ajax调用的，我正在使用admin-ajax进行加载，由于我有很多插件，而且ajax处理程序需要加载所有wp核心，因此加载该代码大约需要2-2.5秒和插件数据，我想知道如何编写一个自定义ajax处理程序，该处理程序仅加载运行以下代码段所需的内容，我的代码摘要是，它通过获取元数据获取woocommerce自定义字段，并读取HTTP标头以进行地理位置定位并实现一些我定义的变量，以创建带有链接的按钮。

function simple_amz_link_ajax() {   
    ?>
    <script>
        jQuery(document).ready(function(){

            jQuery.ajax({
                url: "<?php echo admin_url('admin-ajax.php?action=get_amz_btn'); ?>",
                type: 'POST',
                data: {
                        action: 'get_simple_amz_button',
                        postId: <?php echo get_post()->ID; ?>
                },
                dataType: 'html',
                success: function(response) {
                jQuery("#buy_amz_btn_wrap").html(response);

                }

            }); 
        });
    </script> 
    <!-- end Ajax call to get_simple_amz_button -->

    <div id="buy_amz_btn_wrap">

    <div class="spinner">

看起来您仍然需要在Ajax操作上使用core和WooCommerce函数。因此，基本上，您要做的是使用一个单独的动作，该动作不考虑钩在your_command | awk '{sub(/.*\\/,"")} 1'上的其他动作。不知道这样是否可以节省您的时间，但是您可以尝试：

wp_ajax_*

免责声明：此代码未经测试！

您在这里要做的是设置一个端点，该端点像另一个页面一样运行针对Ajax的所需操作，但是您将使用自定义查询参数<?php function simple_amz_link_ajax() { ?> <script> jQuery( document ).on( 'ready', function () { jQuery.ajax( { url: "<?php echo esc_url( home_url( '?amz=get_amz_btn' ) ); ?>", type: 'POST', data: { postId: <?php echo absint( get_the_ID() ); ?>, nonce: <?php echo wp_create_nonce( 'get_amz_btn' ); ?>, }, dataType: 'html', success: function( response ) { jQuery( '#buy_amz_btn_wrap' ).html( response ); } } ); } ); </script>  <div id="buy_amz_btn_wrap"> <div class="spinner"> <div class="bounce1"></div> <div class="bounce2"></div> <div class="bounce3"></div> </div> </div> <?php } add_action( 'wp_footer', 'simple_amz_link_ajax' ); function simple_amz_button() { if ( check_ajax_referer( 'get_amz_btn', 'nonce', false ) && isset( $_GET['amz'] ) && 'get_amz_btn' === $_GET['amz'] ) { // Variables Declaration. $postId = filter_input( INPUT_POST, 'postId', FILTER_SANITIZE_NUMBER_INT ); $de_asin = get_post_meta( $postId, 'wccaf_de_asin', true ); $country_code = $_SERVER ['HTTP_CF_IPCOUNTRY']; $not_avilable_country = '<div id="amz_not_avilable" class="amz_not_avilable">This product is not avilable in your country yet</div>'; // Get Amazon Button Title. if ( 'de' === ICL_LANGUAGE_CODE ) { $amz_btn_title = 'Kaufen auf Amazon'; $not_avilable_country = '<div id="amz_not_avilable" class="amz_not_avilable">Dieses Produkt ist in Ihrem Land noch nicht verfügbar</div>'; } elseif ( 'en' === ICL_LANGUAGE_CODE ) { $amz_btn_title = 'Buy on Amazon'; $not_avilable_country = '<div id="amz_not_avilable" class="amz_not_avilable">This product is not avilable in your country yet</div>'; } // Geolocation Condition. if ( 'DE' === $country_code || 'AT' === $country_code || 'CH' === $country_code || 'LI' === $country_code || 'EG' === ) { $associate_id = 'bonstato-21'; $access_key = 'HDUHWUIDIUWJDWDWDWD'; $secret_key = 'HDUIWQDUQWUDJUIQJWDJWQD'; $amazon_domain = 'amazon.de'; $asin = $de_asin; } // Get price from amazon $amazon = new AmazonAPI( $associate_id , $access_key, $secret_key , $amazon_domain ); $item = $amazon->item_lookup( $asin )->get_item_data(); if ( 0 != $item->price && null != $item->price ) { ?> <div class="amz_price_wrap_wrap" >Price: <?php echo $item->price; ?></div> <?php } global $post; $product = wc_get_product( $postId ); $type = $product->get_type(); if ( 'simple' === $type && 0 != $item->price && null != $item->price ) { if ( wp_is_mobile() ) { // Amazon Link For Mobile ?> <div class="buy_amz_btn_wrap" > <button type="button" id="buy_amz_btn" class="buy_amz_btn" onclick="window.location='https://<?php echo $amazon_domain ?>/dp/<?php echo $asin ?>/?tag=<?php echo $associate_id ?>';"><i class="fa fa-amazon fa-amz"></i><?php echo $amz_btn_title ?></button> </div> <?php } else { // Amazon Link For PC ?> <div class="buy_amz_btn_wrap" > <button type="button" id="buy_amz_btn" class="buy_amz_btn" onclick="window.location='https://<?php echo $amazon_domain ?>/gp/aws/cart/add.html?AssociateTag=<?php echo $associate_id ?>&ASIN.1=<?php echo $asin ?>&Quantity.1=1';"><i class="fa fa-amazon fa-amz"></i><?php echo $amz_btn_title ?></button> </div> <?php } } elseif( 'simple' === $type && 0 == $item->price ) { echo $not_avilable_country; } if ( is_null( $item->price ) ) { echo $not_avilable_country; } die(); } } add_action( 'template_redirect', 'simple_amz_button' );，而不是使用漂亮的永久链接。（实际上是一个单独的amz）。这就是为什么我们使用wp-ajax.php钩子检查自定义查询参数是否已定义并具有值，如果是，则停止呈现除Ajax动作以外的任何内容。
