同学，你好，注意一下旧密码命名是old_pwd不是pwd，表单的代码如下：

class PwdForm(FlaskForm):
    old_pwd = PasswordField(
        label="旧密码",
        validators=[
            DataRequired("请输入旧密码！")
        ],
        description="旧密码",
        render_kw={
            "class": "form-control",
            "placeholder": "请输入旧密码！",
        }
    )
    new_pwd = PasswordField(
        label="新密码",
        validators=[
            DataRequired("请输入新密码！")
        ],
        description="新密码",
        render_kw={
            "class": "form-control",
            "placeholder": "请输入新密码！",
        }
    )
    submit = SubmitField(
        '编辑',
        render_kw={
            "class": "btn btn-primary",
        }
    )

    def validate_old_pwd(self, field):
        from flask import session
        pwd = field.data
        name = session["admin"]
        admin = Admin.query.filter_by(
            name=name
        ).first()
        if not admin.check_pwd(pwd):
            raise ValidationError("旧密码错误！")

html代码如下：

<form role="form" method="post">
    <div class="box-body">
        <div class="form-group">
            <label for="input_pwd">{{ form.old_pwd.label }}</label>
            {{ form.old_pwd }}
            {% for err in form.old_pwd.errors %}
            <div class="col-md-12">
                <font style="color:red">{{ err }}</font>
            </div>
            {% endfor %}
        </div>
        <div class="form-group">
            <label for="input_newpwd">{{ form.new_pwd.label }}</label>
            {{ form.new_pwd }}
            {% for err in form.new_pwd.errors %}
            <div class="col-md-12">
                <font style="color:red">{{ err }}</font>
            </div>
            {% endfor %}
        </div>
    </div>
    <div class="box-footer">
        {{ form.csrf_token }}
        {{ form.submit }}
    </div>
</form>

同学，你好，你检测old_pwd是否提交到服务器端，你截取一下修改密码的视图代码以及html代码给我！

  老师，两端代码我已经提交到回答里面了。这里粘贴不了。
