Question

有没有办法可以得到一个复选框数组的计数，比如有4个数组（yeswb[], yesab[], yesal[], yesvb[]）。需要获取数组yeswb[], yesab[], yesal[]和yesvb[]的计数，比较它们中的最大计数并在文本字段中显示特定值。

<form action="checkbox.php" method="POST">
                        <table class="table table-striped table-bordered table-hover" id="dataTables-example">
                                    <thead>

                                        <th>Indicator/Symptom</th>

例如，yeswb[]的计数为4，yesab[]的计数为3，yesvb[]的计数为1，我将如何生成{{1}的语句在文本字段中？（因为计数为4 yeswb[] wins是最大的）提前谢谢你。

Answer 1

在checkbox.php

中

$mFinalArray = [];
foreach($_POST as $index => $post){
    $mFinalArray[$index] = count($post);
}

    $biggestCategory = array_search(max($mFinalArray), $mFinalArray);

    print_r($mFinalArray);

    print_r($biggestCategory);

所选表格的示例：

输出：

Array
(
    [yeswb] = 3
    [yesab] = 2
    [yesvb] = 2
)

yeswb

信息：

$index：数组的键（yeswb，yesab，yesvb）

$post：循环中的当前数组

$_POST：所有$_POST变量的数组

*此外，在您的表格更改

<td><input type="checkbox" name="yeswb[]" value="Headache"></td>
<td><input type="checkbox" name="nowb[]" value="No Headache"></td>

要

<td><input type="checkbox" name="yeswb[]" value="Yes"></td>
<td><input type="checkbox" name="nowb[]" value="No"></td>

在php中计算Checkbox数组，在文本框中显示特定值
