<title>Welcome to Chorelistings - Log in Here</title>
<!--[if lt IE 9]><script src="//html5shim.googlecode.com/svn/trunk/html5.js"></script><![endif]-->
</head>
<body>
<form action="test.php" class="login">
<h1>Chore Listings </h1>
<input type = "email" id="email" name = "email" class = "login-input" placeholder = "Username (Email)">
<input type="password" name="password " id ="password" class="login-input" placeholder="Password">
<input type="submit" value="Login" class="login-submit">
<p class="create-account"><a href="register.html">Create Account</a></p>
<p class="login-help"><a href="index.html">Forgot password?</a></p>

You have no method on your form, so it's defaulting to GET, which doesn't send $_POST values. 您的表单上没有method ，因此默认为GET，它不会发送$_POST值。
Add method="post" to your <form> tag. 将method="post"添加到您的<form>标记中。

A few things here. 这里有几件事。 Your form does not specify a request method. 您的表单未指定请求方法。 Add a method attribute to your form tag like so: 将method属性添加到表单标签中，如下所示：
<form method="post" action="test.php" class="login">
Next, just a side-note, there's no need for spaces when specifying your attributes, eg: 接下来，只是一个注释，在指定属性时不需要空格，例如：
<input type = "email" id="email" name = "email" class = "login-input" placeholder = "Username (Email)" />
You'll be good to go with: 您将可以搭配使用：
<input type="email" id="email" name="email" class="login-input" placeholder="Username (Email)" />
A few (less common) things to think about -- make sure your .htaccess is not rewriting any post requests in an unwanted way. 需要考虑的一些（较不常见）的事情-确保您的.htaccess不会以不需要的方式重写任何发布请求。 If you happen to have any file uploads within your form(s), make sure you specify the enctype attribute on your form eg: 如果您碰巧在表单中上传了任何文件，请确保在表单上指定enctype属性，例如：
enctype="multipart/form-data"
Best of luck! 祝你好运！

Firstly, try adding method="post" to the <form> tag: 首先，尝试将method="post"添加到<form>标签：
<form action="test.php" class="login" method="post">
Secondly, inside your test.php file, try debugging what was actually sent: 其次，在您的test.php文件中，尝试调试实际发送的内容：
<?php
print_r($_POST);
// or
var_dump($_POST);
// or for more info
print_r($_REQUEST);
?>
Thirdly, try to remove whitespaces when defining your input fields in html: 第三，尝试在html中定义输入字段时删除空格：
<input type="email" id="email" name="email" class="login-input" placeholder="Username (Email)">
And finally, add <submit> before closing </form> to your form to actually post the data. 最后，在关闭</form> <submit>之前将<submit>添加到表单中以实际发布数据。 Currently, I see you have links ( <a href> ) but that won't submit the form. 目前，我看到您有链接（ <a href> ），但是不会提交该表单。
So your final html should look (simplified) like that: 因此，最终的html应该看起来像（简化）一样：
<form method="post" action="test.php">
<input type="text" name="email">
<submit>
</form>
