真的可以得到任何人的帮助。这是我需要完成的；

我正在处理一个有 6 个复选框（每个都有自己的值）的表单。现在，在一次单击多个 chkbox 时，在提交表单时，我想检索分配给那么多 chkbox 的值。用户可以选择随机复选框。

我的代码：

将您的复选框命名为数组，例如

<input type="checkbox" name="cbname[]" value="value 1" /> Value 1 <br>
<input type="checkbox" name="cbname[]" value="value 2" /> Value 2 <br>
<input type="checkbox" name="cbname[]" value="value 3" /> Value 3 <br>
<input type="checkbox" name="cbname[]" value="value 4" /> Value 4 <br>

在 PHP 中检索值

 <?php 
    if (isset($_POST['cbname'])) 
    {
        $checkBoxArray = $_POST['cbname']; 

        //Comma seprated checkbox values as single string
        $checkBoxComma = implode(",", $checkBoxArray); 

       //Loop through values
        foreach ($checkBoxArray  as $value)
        {
          echo $value . "<br>";
        }

       //Print array
         print_r($checkBoxArray); 
    }

?>

为所有复选框分配相同的名称，testchkbox[]并且在表单提交时，您可以检索所有选定复选框的值。

使用$chckvalues = $_POST['testchkbox'];

对于更优化的代码，您可以为其创建可用值列表和标题（在数组中或来自 DB 的源中）。在这种情况下，您可以使用 foreach 检查和打印用户选择。

查看代码并在http://demos.webtricks.pro/so/selected-checkbox/尝试

<?php
    // List of avaibale values
    $technologies = array (
        1 => "Kingspan Solar",
        "Solar PVT",
        "Insulation",
        "Gas boiler",
        "Oil boiler",
        "Heat recovery ventilation"
    );

?>

<html>
    <head>
    </head>
    <body>
        <form action="" method="post">
            <?php foreach ($technologies as $techId => $tech) : ?>
                <input type="checkbox" name="technologies[]" value="<?php echo $techId;?>" /> <?php echo $tech;?><br/>
            <?php endforeach;?>
            <input type="submit" name="formSubmit" value="Get The Info"><br/>
            <?php
            // If 'technologies' is set int request - user click button
            if (isset($_REQUEST['technologies'])) {
                //$_REQUEST['technologies'] - array with selected checkboxes values
                $techs = $_REQUEST['technologies'];
                foreach ($techs as $techId) {
                    echo "{$techId}. {$technologies[$techId]}<br/>";
                }
            }
            ?>
        </form>

    </body>
