遍历Flask中提交的表单字段? [英] Iterating over submitted form fields in Flask?

问题描述

在Flask 0.8中，我知道我可以使用form.fieldname.data访问单个表单字段，但是有一种简单的方法可以遍历所有表单字段吗?我正在构建电子邮件正文，我想遍历所有字段并为每个字段创建一个字段名/值条目，而不是通过命名每个字段并附加来手动创建它.

In Flask 0.8, I know I can access individual form fields using form.fieldname.data, but is there a simple way of iterating over all the form fields? I'm building an email message body, and I'd like to loop over all the fields and create a fieldname/value entry for each, as opposed to manually building it by naming each field and appending.

推荐答案

我怀疑您正在使用 WTForms .

您可以遍历表单数据:

for fieldname, value in form.data.items():
    pass

您可以遍历所有表单字段:

You can iterate over all form fields:

for field in form:
    # these are available to you:
    field.name
    field.description
    field.label.text
    field.data
