HTML代码

0<input type="checkbox" name="count[]" id="count[]" value="0"/>
<input type="hidden" name="language[]" id="language" value="C++"/>C++ 
<input type="hidden" name="price[]" id="price" value="700"> <br/>

1<input type="checkbox" name="count[]" id="count[]" value="1"/>
<input type="hidden" name="language[]" id="language" value="Assembler"/>Assembler 
<input type="hidden" name="price[]" id="price" value="600"><br/>

这是PHP

<?php

if(isset($_POST['sbt'])){ <br/>
  $count = $_POST['count']; <br/>
  $sub_menu = $_POST['sub_menu']; <br/>
  $sub_price = $_POST['sub_price']; <br/>

foreach($count as $j)

   echo $sub_menu[$j] . '['.$sub_price[$j]. ']' ;<br/>
}<br/>
?>

如何计算总和 - 已选中复选框的总价格？

例如：结果应显示为：

所选编程语言的总价格： C ++，Java = 1200 $

Answer 1

由于价格是以数组形式提交的，因此您可以计算总计如下：

$totals = 0;
foreach ($_POST['price'] as $value) {
    $totals += (int)$value;
}
echo 'Total Price of Selected Programming Languages :', implode(',', $_POST['language']), ' = ', $totals, '$';

如果您想按语言对总计进行分组：

$prices = [];
foreach ($_POST['price'] as $key => $value) {
    if (empty($prices[$_POST['language']])) {
        $prices[$_POST['language']] = (int)$value;
    }
    else {
        $prices[$_POST['language']] += (int)$value;
    }
}

然后你可以遍历这个新数组并按语言输出总数：

echo 'Total Price of Selected Programming Languages ';
foreach($prices as $language => $total) {
    echo "{$language}: {$total}, ";
}

具有不同值的PHP多个复选框数组 - 获取选中复选框的总价格
