从多个复选框返回数组的$POST_

Question

嗨，我已经看过其他答案了，他们说要添加name=，checkbox[]来让数组返回，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']

是一个数组而不是一个字符串，你也拼写错了它的$_POST，所以你需要遍历它来post，如下所示：

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

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

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

Answer 2

运行良好:您只需要使用$_POST和print_r来查看数组的内容。试试这个，你会发现它工作得很好。

顺便说一下，您的options上不需要name属性

<form method="post" action="<?=$PHP_SELF?>">
    <select name="suburb[]" class="select" multiple="multiple" id="suburb">
        <option selected="selected" value="Southbank">Southbank</option>
        <option selected="selected" value="Melbourne">Melbourne</option>
        <option selected="selected" value="Docklands">Docklands</option>
        <option selected="selected" value="South Melbourne">South Melbourne</option>
        <option selected="selected" value="West Melbourne">West Melbourne</option>
        <option selected="selected" value="Point Cook">Point Cook</option>
        <option selected="selected" value="Sanctuary Lakes">Sanctuary Lakes</option>
        <option selected="selected" value="Truganina">Truganina</option>
        <option selected="selected" value="Williams Landing">Williams Landing</option>
    </select>
    <button type="submit">test</button>
</form>
<?php
print_r($_POST['suburb']);
?>

您要查找的变量是$_POST，而不是$POST_；有关更多详细信息，请参阅the PHP reference on $_POST。

否则，从您所展示的内容来看，它可能是好的。如果仍然不起作用，也要为表单标记添加HTML。
