php提交表单验证不通过返回填写内容的相关问题

<?php
/**
* registe page
*/

if (isset($_POST["submit"])) {
processForm();
} else {
displayForm(array());
}

function setField($nameField) {
if (isset($_POST[$nameField])) {
echo $_POST[$nameField];
}
}

function processForm() {
$requiredFields = array('username', 'userpwd', 'userpwd2');
$missingFields = array();
foreach ($requiredFields as $requiedField) {
if (!isset($_POST[$requiedField]) or !$_POST[$requiedField]) {
$missingFields[] = $requiedField;
}
}

if ($missingFields) {
displayForm($missingFields);
} else {
displayThanks();
}
}

function displayForm($missingFields) {
echo "<h1>Register Page</h1><hr>";
if ($missingFields) {
echo "<h3>Sorry, there is some field for you to sign, please check it again</h3>";
} else {
echo "<h3>Welcome to register our party, you would be our member, just afer sign this message dowm...</h3>";
}

?>

<form action="" method="post">

<table>
<tr>
<td>用户名*:</td>
<td><input type="text" name="username" id="username" value="<?php setField("username")?>"></td>
</tr>
<tr>
<td>密 码 *：</td>
<td><input type="password" name="userpwd" id="userpwd" value=""></td>
</tr>
<tr>
<td>确 认 *：</td>
<td><input type="password" name="userpwd2" id="userpwd2" value=""></td>
</tr>
<tr>
<td><input type="submit" name="submit" id="submit" value="提交"></td>
</tr>
</table>

<?php
}
function displayThanks() {
echo "<h3>Thanks for resgisting our party...</h3>";
}
?>

现在问题是：我全部输入值了，却无法显示displayThanks()函数，我找不到原因了，希望phper帮我看下哪里错了，小弟也没分了，只要请求好心人帮助了，谢谢

Answer 1

我把代码复制了，结果可以显示

Answer 2

/*将以下代码*/
foreach ($requiredFields as $requiedField) {
if (!isset($_POST[$requiedField]) or !$_POST[$requiedField]) {
$missingFields[] = $requiedField;
}
}

if ($missingFields) {
displayForm($missingFields);
} else {
displayThanks();
}

/*---------------------------------------------------------------*/
改写成：
foreach ($requiredFields as $key => $value) {
if (empty($value)) {
$missingFields[] = $key;
}

}
if (count($missingFields)>0) {
displayForm($missingFields);
} else {
displayThanks();
}
