我有一个获取患者数据并将其发送到数据库的表单;但是，单击提交按钮时会发生错误; 

Notice: Undefined index: $patient_lastname line 14

任何人都可以告诉我为什么会出现这个错误吗？

您在发布值之前错误地添加了$。

更改此

$patient_lastname = ($_POST['$patient_lastname']);
$gender = ($_POST['$gender']);
$dateOfBirth = ($_POST['$dateOfBirth']);
$monthOfBirth = ($_POST['$monthOfBirth']);
$yearOfBirth = ($_POST['$yearOfBirth']);

到

$patient_lastname = ($_POST['patient_lastname']);
$gender = ($_POST['gender']);
$dateOfBirth = ($_POST['dateOfBirth']);
$monthOfBirth = ($_POST['monthOfBirth']);
$yearOfBirth = ($_POST['yearOfBirth']);

在此处查看您的帖子输入值名称属性

<input type="text" name="patient_lastname" size="30" required="true" />

同样适用于其他人。

你的错误是自我定义的..它说你在尝试获取值的数组中没有这样的键

在$ _POST

中的值前面删除'$'

替换

$patient_lastname = ($_POST['$patient_lastname']); 到

$patient_lastname = ($_POST['patient_lastname']);

在你的代码中还有其他一些像这样。

请避免使用mysql_ *切换到PDO或mysqli _ *
