【问题描述】：

我正在为要求 3 个输入的表单创建 AJAX 功能 - 床、浴室、频率。我希望输出是价格。所以用户在输入的时候，只会输出我创建的Array对应的价格。

PHP 代码片段（数组）：

 $pricing = array (
    array ('frequency' => "one", 'beds' => 1 , 'baths' => 1 , 'price' => 90),
    array ('frequency' => "one", 'beds' => 1 , 'baths' => 1.5 , 'price' => 113),
    array ('frequency' => "one", 'beds' => 1 , 'baths' => 2 , 'price' => 113),
    array ('frequency' => "one", 'beds' => 2 , 'baths' => 2.5 , 'price' => 135),
    array ('frequency' => "weekly", 'beds' => 3 , 'baths' => 3 , 'price' => 135),
    array ('frequency' => "weekly", 'beds' => 3 , 'baths' => 3.5 , 'price' => 158),
    array ('frequency' => "biweekly", 'beds' => 4 , 'baths' => 4 , 'price' => 158),
    array ('frequency' => "biweekly", 'beds' => 4 , 'baths' => 4.5 , 'price' => 180),
    array ('frequency' => "monthly", 'beds' => 5 , 'baths' => 5 , 'price' => 180),
    array ('frequency' => "monthly", 'beds' => 5 , 'baths' => 5.5 , 'price' => 203),
    array ('frequency' => "monthly", 'beds' => 6 , 'baths' => 6 , 'price' => 203)
);

我设法传递了输入的值，但我的函数不起作用。显然我可以回显（回显 $selected_frequency_id;）从我的表单中选择的值，但我不能回显价格。我的功能不正确吗？我找不到 foreach 循环有什么问题。请看下面的代码：

PHP 代码继续：

function ajax_update_price() {

$selected_bed_id = $_POST['bedID'];
$selected_bath_id = $_POST['bathID'];
$selected_frequency_id = $_POST['frequencyID'];

//echo $selected_frequency_id;

    foreach( $pricing as $element ) {
        if( $element['frequency'] == $selected_frequency_id && $element['beds'] == $selected_bed_id && $element['baths'] == $selected_bath_id) {
             echo $element['price'];
             break;
    }
 } 

    wp_die(); 
}

【问题讨论】：

这和 JavaScript 有什么关系？

【解决方案1】：

function ajax_update_price() {
  global $_POST;


$selected_bed_id = $_POST['bedID'];
$selected_bath_id = $_POST['bathID'];
$selected_frequency_id = $_POST['frequencyID'];


foreach( $pricing as $element ) {
    if( ($element['frequency'] == $selected_frequency_id) && ($element['beds'] == $selected_bed_id) && ($element['baths'] == $selected_bath_id)) {
         echo $element['price'];
         break;
   }
  } 

wp_die(); 
}

但我有更漂亮的解决方案：

 $pricing["one"]["1"]["1"] = 90;
 $pricing["one"]["1"]["1.5"] = 113;
 $pricing["one"]["1"]["2"] = 113;
 $pricing["one"]["2"]["2.5"] = 135;
 $pricing["one"]["2"]["2.5"] = 135;
 $pricing["weekly"]["3"]["3"] = 135;
 $pricing["weekly"]["3"]["3.5"] = 158;
// and so on, i think you understand how to continue

新功能将是：

function ajax_update_price() {
  global $_POST;


$selected_bed_id = $_POST['bedID'];
$selected_bath_id = $_POST['bathID'];
$selected_frequency_id = $_POST['frequencyID'];

if ($pricing[$selected_frequency_id][$selected_bed_id][$selected_bath_id])
    print $pricing[$selected_frequency_id][$selected_bed_id][$selected_bath_id]

  wp_die(); 
}

谢谢！会试试这个！
对不起，新手。我完全复制了您的第一个建议，但它仍然不起作用。我还复制了您的第二个建议并删除了我的原始数组，但仍然无法正常工作。
