    </form>
    &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
    <label> Note: All <font color="#FF0000">*</font> Fields are required please fill them all</label>
</body>

有什么建议吗？

Answer 1

这个拼写错误$_REQUEST['lasttName']应为$_REQUEST['lastName']

另外，这个<input type="password" id="confirmPassword" required = "required"/>没有其他参考，所以我不确定你为什么要使用/包含它。

我也没有在validation()中看到onSubmit="return validation()"函数的任何引用，所以如果你没有它的功能（我在你发布的代码中没有看到），那么你需要删除它。

我注意到的另一件事是有一些包含空格的命名表单元素;那是无效的。

I.e。：如果您决定稍后在PHP中使用它们，则name="Create Employee"使用下划线name="Create_Employee"和name="Clear All" name="Clear_All"。

无法使用php _POST方法从我的表单中获取数据
