如何在 Symfony2 中显示月-年下拉列表 [英] How to display a month-year dropdown in Symfony2

问题描述

在我的应用程序中，用户 hsa 仅通过在两个下拉列表中选择月份和年份来给出日期.我怎样才能做到这一点?

In my application, the user hsa to give a date by only selecting a month and a year in two dropdown lists. How can I achieve that?

这是我迄今为止尝试过的:

Here is what I've tried so far :

在我的表单中:

$builder->add('date1', 'date', array(
 'widget'      => 'choice',
 'empty_value' => '',
 'format'      => 'MMMM-yyyy',
 'input'       => 'datetime',
 'years'       => range(date('Y'), date('Y') - 30, -1)
)

它实际上可以正常工作并完全按照我的意愿显示它，但是在验证表单时，我收到一个错误:

which actually works and displays it exactly as I want but when validating the form, I get an error :

This value is not valid

推荐答案

信用卡有效期示例:

$builder->add('expirationDate', 'date', array(
 'label' => 'Expiration date',
 'widget' => 'choice',
 'empty_value' => array('year' => 'Year', 'month' => 'Month', 'day' => 'Day'),
 'format' => 'dd-MM-yyyy',
 'input' => 'string',
 'data' => date('Y-m-d'),
 'years' => range(date('Y'), date('Y') + 10),
));

那么你必须手动渲染这个字段.

Then you must render this field manually.

表单的树枝模板:

{{ form_row(form.expirationDate, {'date_pattern': '<span style="display: none;">{{ day }}</span> {{ month }} <span class="delim">&#47;</span> {{ year }}'}) }}

覆盖 date_pattern 将隐藏日期选择.您将获得月/年格式.

Overriding date_pattern will hide day select. You will get month / year format.
