第42行是错误。我不确定为什么它一直说它不是一个数组是一个部分，但未能找到数组在第42行。我试图将行更改为($_POST['CINS']作为$cNum => $v)和($CINS作为$cNum => $v)。如有任何见解或帮助，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
?>
您的复选框名称应该像下面这样将其视为数组
<input type="checkbox" name="CINS[]" value = "1" />
<input>名称是一个数组，我发现了一个不应该在那里的备用</p>。
你的编码风格会引起很多头痛。我已经整理了一下，我想这种风格会更容易驾驭。
