我尝试进行创建自动密码的注册并通过电子邮件发送，但每当执行代码时，我都会在所有字段中收到此错误（注意：未定义的索引:)。请帮忙

如果未设置$_POST['name']，则会发出通知，因此您可以使用：
if (isset($_POST['name']))
{
if ($_POST['name'] == '')
{
$_SESSION['error']['name'] = "First Name is required.";
}
}

您错过了输入name并使用错误的type使用type ="text"
缺少input name将无法获取您的数据，而且没有type="pharmacy"等等......
<div class="form-group">
<input type="text" name="pharmacy" class="form-control" id="pharmacy" placeholder="Pharmacy Name">
</div>
<div class="form-group">
<input type="text" name="rx30licence" class="form-control" id="rx30licence" placeholder="RX30 Licence">
</div>
<div class="form-group">
<input type="text" name="city" class="form-control" id="city" placeholder="City">
</div>
<div class="form-group">
<input type="text" name="phone" class="form-control" id="phone" placeholder="Phone#">
</div>
<div class="form-group">
<input type="text" name="fax" class="form-control" id="fax" placeholder="Fax#">
</div>
<span class="input-group-btn">
<input name="submit" type="submit" value="Submit"/>
</span>
</div>
这些错误的第一个解决方法是使用@Mark M所说的print_r($_POST)
也可以在条件中使用echo来检查特定条件是否正在执行
