我有一个获取患者数据并将其发送到数据库的表单;然而，一个错误是发生当提交按钮被点击;
Notice: Undefined index: $patient_lastname line 14
谁能告诉我为什么会出现这个错误?

您错误地在post值之前添加了$。
改变这
$patient_lastname = ($_POST['$patient_lastname']);
$gender = ($_POST['$gender']);
$dateOfBirth = ($_POST['$dateOfBirth']);
$monthOfBirth = ($_POST['$monthOfBirth']);
$yearOfBirth = ($_POST['$yearOfBirth']);
$patient_lastname = ($_POST['patient_lastname']);
$gender = ($_POST['gender']);
$dateOfBirth = ($_POST['dateOfBirth']);
$monthOfBirth = ($_POST['monthOfBirth']);
$yearOfBirth = ($_POST['yearOfBirth']);
查看你的post输入值name属性
<input type="text" name="patient_lastname" size="30" required="true" />
你的错误是自我定义…它表示在数组中没有这样的键你可以从中获取值
删除$_POST中value前面的$
代替 $patient_lastname = ($_POST['$patient_lastname']);
$patient_lastname = ($_POST['patient_lastname']);
在你的代码中还有一些像这样的
请避免使用mysql_*切换到PDO或mysqli_*
