问题：如何在我的电子邮件中显示选定的复选框？

我创建了一个调查 ( http://www.hello-rio.com/surveyonshoes/ )，并且我试图让我选择的复选框在提交表单时显示在我的电子邮件中。在这方面我是一个完全的菜鸟，任何帮助将不胜感激

这是我的 html 示例复选框代码（在 index.html 中）：

<label for="colors">What colors do you own? (check all that apply)</label>
<div class="twocol"><input type="checkbox" name="color_flats[]" value="black">black </div>
<div class="twocol"><input type="checkbox" name="color_flats[]" value="brown">brown </div>
<div class="twocol"><input type="checkbox" name="color_flats[]" value="beige">beige </div>
<div class="twocol"><input type="checkbox" name="color_flats[]" value="white">white </div>
<div class="twocol"><input type="checkbox" name="color_flats[]" value="gold">gold </div>
<div class="twocol"><input type="checkbox" name="color_flats[]" value="silver">silver </div>
<div class="twocol"><input type="checkbox" name="color_flats[]" value="red">red </div>
<div class="twocol"><input type="checkbox" name="color_flats[]" value="blue">blue </div>
<div class="twocol"><input type="checkbox" name="color_flats[]" value="yellow">yellow </div>
<div class="twocol"><input type="checkbox" name="color_flats[]" value="green">green </div>
<div class="twocol"><input type="checkbox" name="color_flats[]" value="orange">orange </div>
<div class="twocol"><input type="checkbox" name="color_flats[]" value="purple">purple </div><br>
<label for="others">Others</label>
<input type="text" name="color_flats[]" class="others" />

继承人完整的php代码（contact.php）：

$myEmail  = "johndoe@domain.com";

function show_error($myError)

        <?php echo $myError; ?>

    </body>
    </html>
<?php
exit();
}
?>

我已经尝试过各种代码，例如 implode、if 语句、foreach 等。似乎无法正确...

$color_flats = check_input(implode("," , $_POST['color_flats']));

$message = "...

由于$color_flats是一个数组，因此您需要在每个数组上循环

foreach($color_flats as $whatever){
    echo $whatever;
}

或者您可以将其内爆以制作一个唯一的字符串：

echo implode(',', $color_flats);

<?php

#   Default Vars
$_color_flats = '';
if(isset($color_flats) === TRUE){
    #   Is Array ?
    if(is_array($color_flats) === TRUE){
        #   Count
        $c = count($color_flats);

        #   Loop
        for($i=0; $i < $c; $i++){
            $_color_flats.= (isset($color_flats[$i]) === TRUE ? $color_flats[$i] : '').($i == ($c-1) ? '' : ($i == $c-2 ? ' and ' : ', '));
        }
    }
}

echo $_color_flats;

?>
