Php Can'；我不理解为什么设置了数组，但处理后数组为空

第42行是错误。我不知道为什么它一直说它不是数组，而是一个部分，但在第42行找不到数组。我尝试将行更改为（$_POST['CINS']作为$cNum=>$v）和（$CINS作为$cNum=>$v）。如有任何见解或帮助，将不胜感激

<?php
$title = "fTest.php";
$action=$_SERVER['PHP_SELF'];
include("html-head.inc");
echo <<<HEREDOC
<header>
<h1>$title</h1>
</header>
HEREDOC;

if (!isset($_POST['submit']))
{ 
        echo "<form method=\"post\" action=\"$action\">";
$CINS = array('101' => "CINS101",
                '108' => "CINS108",
                '121' => "CINS121",
                '251' => "CINS251",
                '254' => "CINS254");
        echo "<p>Please pick your CINS classes:</p>";
        echo "<ul>\n";
foreach ($CINS as $key => $value)
{ 
        echo "<li>";
        echo "<input type=\"checkbox\" name=\"CINSc\" value=\"$value\"/>CINS$key"    ;
        echo "</li>\n";
}                 
        echo "</ul>\n"; 
        echo "<input type=\"reset\" name=\"reset\" value\"Reset\" />";
        echo "<input type=\"submit\" name=\"submit\" value\"Submit\" />";
        echo "</p>";
echo is_array($CINS) ? 'Array' : 'Not an array';
echo "\n";
        echo "</form>";
} // ends IF PORTION for ISSET
else      
{         
if (count($_POST['CINS'] > 0 ))
{         
        echo "<h2> Your picks are: </h2>\n";
        echo "<ul>\n";
echo is_array($CINS) ? 'Array' : 'Not an array';
foreach ($_POST['CINS'] as $cNum => $v)  //This is the error.
{
        echo "\t<li>$v</li>\n";
} // end of FOREACH cins
        echo "</ul>\n";
} // end of IF count CINS
} // end of ELSE portion for ISSET
?>

<代码> > p>您的复选框名称应如下所示，将其视为数组

<input type="checkbox" name="CINS[]" value = "1" />


名称是一个数组，我找到了一个不应该存在的备用名称

你的编码风格会引起很多麻烦。我把它清理了一点，我想这种款式会更容易处理

<?php
$title = "fTest.php";
$action=$_SERVER['PHP_SELF'];
include("html-head.inc");
?>

<header>
<h1><?=$title?></h1>
</header>

<?php if (!isset($_POST['submit'])): ?>
    <?php $CINS = array('101' => "CINS101",
                        '108' => "CINS108",
                        '121' => "CINS121",
                        '251' => "CINS251",
                        '254' => "CINS254"); ?>
    <form method="post" action="<?=$action?>">
        <p>Please pick your CINS classes:</p>
        <ul>
        <?php foreach ($CINS as $key => $value): ?>
            <li>
            <input type="checkbox" name="CINS[]" value="<?=$value?>" />CINS<?=$key?>
            </li>
        <?php endforeach; ?> 
        </ul>
        <input type="reset" name="reset" value"Reset" />
        <input type="submit" name="submit" value"Submit" />
        </p> <!-- THIS TAG IS EXTRA WHERE DID IT COME FROM -->
        <?= is_array($CINS) ? 'Array' : 'Not an array' ?>
    </form>
<?php else if (count($_POST['CINS'] > 0 )): ?>
    <h2>Your picks are: </h2>
    <ul>
    <?= is_array($CINS) ? 'Array' : 'Not an array' ?>
    <?php foreach ($_POST['CINS'] as $cNum => $v): ?>
        <li><?=$v?></li>
    <?php endforeach; ?>
    </ul>
<?php endif; ?>


你的选择是：



请将数组粘贴到此处打印（$\u POST['CINS'）；唯一出现的是无效参数错误命名约定与作为数组处理的
$\u POST
无关。@aguyfromhere:It's ok for
$\u POST
。关于
$\u POST['CINS']
？@nauphal，当您将HTML中的命名项传递给PHP处理程序时，superglobals$\u POST和$\u会被视为对象，因此它们内部已经有嵌套数组。名为CINS的HTML输入自动被称为$_REQUEST['CINS']。@aguyfromhere我感到困惑，您是否建议复选框的名称正确为
CINS
，而不是
CINS[]
？@aguyfromhere:不明白您想说什么。老实说，我不太确定该标记来自何处。我以为我把它拿出来了。但是谢谢你指出。你找到解决这个问题的方法了吗？
