php - $POST_ 从多个复选框返回数组

Question

您好，我看过其他答案，他们说要添加 name=checkbox[] 以使数组返回，但它似乎不起作用。

HTML 是:

<select class="select" multiple="multiple" name="suburb[]" id="suburb">
<option selected="selected" name="suburb[]" value="Southbank">Southbank</option>
<option selected="selected" name="suburb[]" value="Melbourne">Melbourne</option>
<option selected="selected" name="suburb[]" value="Docklands">Docklands</option>
<option selected="selected" name="suburb[]" value="South Melbourne">South Melbourne</option>
<option selected="selected" name="suburb[]" value="West Melbourne">West Melbourne</option>
<option selected="selected" name="suburb[]" value="Point Cook">Point Cook</option>
<option selected="selected" name="suburb[]" value="Sanctuary Lakes">Sanctuary Lakes</option>
<option selected="selected" name="suburb[]" value="Truganina">Truganina</option>
<option selected="selected" name="suburb[]" value="Williams Landing">Williams Landing</option>

PHP 代码是:

    $message .= "<tr><td><strong>Interested Suburbs:</strong> </td><td>" . strip_tags($POST_['suburb']) . "</td></tr>";

Answer 1

$_POST['suburb']

数组不是字符串吗？你把它拼错了 $_POST，所以你需要循环遍历它才能像这样发布:

$message .= "<tr><td><strong>Interested Suburbs:</strong> </td><td>";

foreach ($_POST['suburb'] as $suburb)
{
    $message .= strip_tags($suburb) . "<br />\n";
}

$message .= "</td></tr>";
