我不知道如何让 required_if 验证规则起作用。它似乎没有运行,但可能是因为我没有正确使用它。所有其他规则都运行,但这条规则似乎不起作用。有人可以告诉我我做错了什么吗?
这是 HTML(带有刀片)
<div class="col-lg-6 col-md-6 col-sm-6 col-xs-6">
{{ Form::checkbox('class_of_mail[]', 'Nonprofit Standard (Bulk)', null, ['data-id' => 'non-profit-standard-bulk']) }} Nonprofit Standard (Bulk)* <br />
{{ Form::checkbox('class_of_mail[]', 'Presorted Standard (Bulk)', null, ['data-id' => 'presorted-standard-bulk']) }} Presorted Standard (Bulk)* <br />
{{ Form::checkbox('class_of_mail[]', 'Presorted First Class (500 pieces or more)', null, ['data-id' => 'presorted-first-class']) }} Presorted First Class (500 pieces or more) <br />
{{ Form::checkbox('class_of_mail[]', 'First Class', null, ['data-id' => 'first-class']) }} First Class <br />
{{ Form::checkbox('class_of_mail[]', 'Campus', null, ['data-id' => 'campus']) }} Campus <br />
{{ Form::checkbox('class_of_mail[]', 'Other', null, ['data-id' => 'class_of_mail_other']) }} Other <br />
{{ Form::checkbox('class_of_mail[]', 'Customer Provided List', null, ['data-id' => 'class_of_mail_customer_provided_list']) }} I would like to provide my own campus list <br />
</div>
<div id="mailing_class_other_div" class="form-group row hide">
{{ Form::label('mailing_class_other', 'Other Class of Mail', ['class' => 'control-label col-lg-12 col-md-12 col-sm-12 col-xs-12']) }}
<div class="col-lg-5 col-md-5 col-sm-5 col-xs-5">
{{ Form::text('mailing_class_other', null, ['class' => 'form-control input-sm']) }}
</div>
</div>
这是我的控制器中的 $rules 数组。 这种形式没有模型。
$rules = [
'department' => 'required|min:2|max:64',
'purchase_requisition' => 'required|min:2|max:64',
'contact_name' => 'required|min:2|max:64',
'contact_phone' => 'required|min:2|max:32',
'alt_contact_name' => 'required_with:alt_contact_phone',
'alt_contact_phone' => 'required_with:alt_contact_name',
'mailing_subject' => 'required|min:2|max:64',
'mailing_piece_count' => 'required|min:1|max:11',
'class_of_mail' => 'required',
## Here is the required_if validation rule ##
'mailing_class_other' => 'required_if:class_of_mail,Other',
];
$validator = Validator::make($input, $rules, $messages);
if ($validator->fails())
{
$messages = $validator->messages();
return Redirect::to('print-to-mail')->withErrors($validator)->withInput();
}
