从一组复选框中提取值

Question

我一直在努力解决这个问题。我有一个脚本，它从我的网站获取表单帖子，并将数据以格式精美的电子邮件发送到我的电子邮件地址。我遇到的问题是表单必须在用户填写时计算运行总计，其中一部分来自选择框的值作为一个变量，复选框的值作为另一个变量，加在一起形成总计。为了使这项工作，我必须在我的表单中有一个隐藏的复选框，其值为“0”，标记为已选中。因此，我发送到 phpmailer 的数组的索引计数始终至少为 1。当没有选中其他选项并且仅选中隐藏的复选框时，它会在电子邮件中完美返回“未选择选项”。当我选中另一个选项或多个选项时，它会将它们正确发送到带有
标签的表单，以便它们按行顺序显示。问题是，无论我做什么，最后一个 $optiontype 都会重复并在我的电子邮件表单中显示两次。

我认为问题在于我的代码中的最后一个条件语句。

if (isset($_POST['optiontype'])) { $arraycount = count($_POST['optiontype']);

    for ($index = 0; $index < count($_POST['optiontype']); $index++) {
        $value = $_POST['optiontype'][$index];
        
        if ($value == '0' && $arraycount == 1) {
            $value_text = 'No Options Selected';
        }  
        if ($value == '70') {
            $value_text = '$70 Green Plus';
        }
        if ($value == '75') {
            $value_text = '$75 Subterranean Termite Treatment';
        }
        if ($value == '50') {
            $value_text = '$50 Freezer-Standalone';
        }
        if ($value == '25') {
            $value_text = '$25 Wet Bar Refrigerator/2nd Refrigerator';
        }
        if ($value == '150') {
            $value_text = '$150 Pool/Spa Combo';
        }
        if ($value == '150+0') {
            $value_text = '$150 Additional Pool or Spa';
        }
        if ($value == '300') {
            $value_text = '$300 Salt Water Pool (Includes Pool/Spa Combo)';
        }
        if ($value == '100') {
            $value_text = '$100 Well Pump';
        }
        if ($value == '75+0') {
            $value_text = '$75 Septic System/Sewage Ejector Pump & Septic Tank Pumping';}
        if ($value == '90') {
            $value_text = '$90 External Water Line Repair';
        }
        if ($value == '195') {
            $value_text = '$195 External Water Line + Sewer & Septic Line Repair';
        }  
        
        if ($index < $arraycount) {
            $optiontype .= $value_text . "<br>";
        } else {
            $optiontype .= $value_text;
        }
        
    }

Answer 1

与上面的 cmets 一起工作，我在一个小示例中工作，该示例将有一个名为 $options 的变量，它是来自 $_POST['optiontype'] 中的数组选项的字符串

<?php
$products = [
    '70' => '$70 Green Plus',
    '75' => '$75 Subterranean Termite Treatment',
    '50' => '$50 Freezer-Standalone',
    '25' => '$25 Wet Bar Refrigerator/2nd Refrigerator',
    '150' => '$150 Pool/Spa Combo',
    '150+0' => '$150 Additional Pool or Spa',
    '300' => '$300 Salt Water Pool (Includes Pool/Spa Combo)',
    '100' => '$100 Well Pump',
    '75+0' => '$75 Septic System/Sewage Ejector Pump & Septic Tank Pumping',
    '90' => '$90 External Water Line Repair',
    '195' => '$195 External Water Line + Sewer & Septic Line Repair'
];

$values = [];

// this should come from your real $_POST but I just made it up
// showing an element named notFound as it will be ignored
$_POST = ['optiontype' => ['70', '300', '75+0', 'notFound']];

if (isset($_POST['optiontype'])) {
    foreach ($_POST['optiontype'] as $option) {
        if(!empty($products[$option])) {
            $values[] = $products[$option];
        }
    }
}

$options = implode("<br>", $values);

var_dump($options);

输出：

string(127) "$70 Green Plus<br>$300 Salt Water Pool (Includes Pool/Spa Combo)<br>$75 Septic System/Sewage Ejector Pump & Septic Tank Pumping"
