【问题描述】：
我第一次尝试注册表格，一直在观看教程视频，我发誓我已遵循所有步骤，但是当我希望姓氏和名字字段成为必填字段时，但当我测试它并点击提交，表单仍然空白处理。
html/php 用于索引页面（我只附上了第一个，因为这是唯一需要 php 的部分）：
<?php
//arrays for error messages
$errors = [];
$missing = [];
if (isset($_POST['submit'])){
$expected = ['gender','title','surname','given','day','month','year','prevsurname','prevfirst','address','city','postcode','state','australian'];
$required = ['surname','given'];
require './includes/process_mail.php';
}
?>
<!DOCTYPE html>
<head>
<title>FORM ASSIGNMENT</title>
<link href="CSS/style.css" rel="stylesheet" type="text/css">
</head>
<body>
<h3 class="head">registration</h3>
<p class="explain">Complete the form below to register.</p>
<!----- ADDED REQUIRED FIELD TEXT USING SPAN CLASS, AS WILL NOT CHANGE THE VISUALS OF THE SITE ----->
<form method="POST" action="handle_form.php">
<fieldset><legend>Sign up below</legend>
<?php if ($errors || $missing) : ?>
<p class="error">Please complete missing field(s) before progressing</p>
<?php endif; ?>
<table width="600" border="2">
<tr>
<input type="radio" name="gender" value="male" checked> Male
<input type="radio" name="gender" value="female"> Female
</tr>
<tr>
<th align="right">Title</th>
<td><select name="title" id="title">
<option value="Default" selected>Select</option>
<option value="Mr">Mr.</option>
<option value="Miss">Miss.</option>
<option value="Ms">Ms.</option>
<option value="Mrs">Mrs.</option>
</select></td>
</tr>
<tr>
<th align="right">Name</th>
<td><label for="surname">Surname:
<?php if ($missing && in_array('surname', $missing)): ?>
<span class="error">Please enter Surname</span>
<?php endif; ?>
</label>
<input name="surname" type="text" id="surname" size="30" maxlength="25"><br>
<label for="given">Given:
<?php if ($missing && in_array('given', $missing)): ?>
<span class="error">Please enter First Name</span>
<?php endif; ?>
</label>
<input name="given" type="text" id="given" size="33" maxlength="25"></td>
</tr>
用于处理错误的 PHP：
<?php
foreach ($_POST as $key => $value){
$value = is_array($value) ? $value : trim($value);
if (empty($value) && in_array($key, $required)){
$missing[] = $key;
$$key = '';
}elseif (in_array($key, $expected)){
$$key = $value;
}
}
PHP 显示处理后的数据：
<!DOCTYPE html>
<head>
<title>FORM ASSIGNMENT</title>
<link href="CSS/style.css" rel="stylesheet" type="text/css">
</head>
<body>
<!----------- PHP CODE TO DISPLAY DATA FROM FORM --------------->
<pre>
<?php
if($_GET){
echo 'Content of the $_GET array;<br>';
print_r($_GET);
}elseif ($_POST){
echo 'Details below <br>';
print_r($_POST);
}
?>
</pre>
<h3>Details Uploaded Successfully!</h3>
<p class="thankyou">Thank you for filling out your details</p>
</body>
</html>
任何提示、提示或滥用都会有所帮助，谢谢。
【问题讨论】：
-
开启错误检查，但我看到了一些
-
在哪里？刚刚运行了一个代码检查，它没有出现编码错误（右括号、大括号等）
-
@ChrisBeechey 您可以在处理
$missing的错误并返回响应或处理表单数据后分享代码吗？
