Question

我正在尝试创建一个计算依赖于国家/地区的定价的页面。我有两个定价层，并希望在选择国家/地区时更新两个单独输入字段中的定价。我可以通过重复两次JQuery和business_plan_calculation函数来做到这一点，但是想知道是否有办法用一个函数做到这一点？

以下是我用两个函数

执行的代码

function country_selector() {

    global $wpdb;

    $results = $wpdb->get_results("SELECT country FROM master_country ORDER BY country ASC");

    foreach ($results as $rows) :
        $option .= '<option value="'.$rows->country.'">';
        $option .= $rows->country;
        $option .= '</option>';
    endforeach;

     ?>

<script type="text/javascript">
    jQuery( document ).ready( function() {

        jQuery( '#country_selector' ).change( function() {
            var countryPOP = jQuery( '#country_selector' ).val();

        jQuery.ajax( {
            url: "<?php bloginfo( 'wpurl' ); ?>/wp-admin/admin-ajax.php",
            type: 'POST',
            data: 'action=business_plan_calculation&countryID=' + countryPOP,

            success: function( results ) {
                jQuery( '#business_plus_price' ).empty();
                jQuery( '#business_plus_price' ).val( results );
                    }
                });

            jQuery.ajax( {
            url: "<?php bloginfo( 'wpurl' ); ?>/wp-admin/admin-ajax.php",
            type: 'POST',
            data: 'action=enterprise_calculation&countryID=' + countryPOP,

            success: function( results ) {
                jQuery( '#enterprise_price' ).empty();
                jQuery( '#enterprise_price' ).val( results );
                    }
                });
            }); 
        });
        </script> <?php

    return '<select id="country_selector"><option value="0" disabled selected>Select Your Country</option>'.$option.'</select>';

}

add_shortcode('country-selector', 'country_selector');


function business_plan_calculation() {

    if(isset($_POST['countryID'])) :

        $parentCat=$_POST['countryID'];

        global $wpdb;
        $results = $wpdb->get_row( "SELECT currency_alpha, ppp_conversion FROM master_country WHERE country='$parentCat'" );

        $endpoint = 'convert';
        $access_key = '3a8c6c408b87705bde661d3d17b938ed';

        $user_currency = $results->currency_alpha;

        $ppp = $results->ppp_conversion;

        $business_plus = ( 65 * $GBPUSDresults * $ppp * $USERGBPresults );
        echo '£'.number_format((float)$business_plus, 2, '.', '').' per year';

        die();

    endif;
}

Answer 1

这实际上很容易实现。

更改您的AJAX PHP函数以返回BOTH值，并返回JSON编码数组。

然后，在你的javascript AJAX成功回调中，获取两个数据，并将它们放入两个单独的输入中。

以下更改被评论以解释发生了什么：

File -> Invalidate Caches/Restart -> Invalid and Restart

注意：在完成问题中的代码之后，会出现很多拼写错误和其他问题。问题不在于修复/改善这些问题，所以我一直坚持向模式展示如何做你想做的事情。如果它不适合您，则需要解决代码中存在的问题。

从php函数填充多个输入框
