Question

我想首先说我是Silver Stripe开发和PHP / MySQL的新手，所以请善待。

我有一个网站要求我有一个定价页面，在定价页面（duh）和主页上显示公司的定价计划。因此，我们的目标是能够使用Pricing.php从我的HomePage.ss页面类型访问数据。

我正在尝试将此作为未来的证据，因此我创建了一个扩展DataObject的ServicePlan.php并使用FieldList创建定价记录并将它们与{{1}相关联页面类型通过Pricing和$has_many关系。基于我有限的知识，这似乎是实现这一目标的最佳方式。

这是我为完成此任务而编写的代码。

ServicePlan.php

$has_one

Pricing.php

class ServicePlan extends DataObject {

private static $db = array (
    'PlanColor' => 'Varchar',
    'PlanName' => 'Varchar',
    'PlanPrice' => 'Varchar',
    'PlanRenewal' => 'Varchar',
);

private static $has_one = array (
    'Pricing' => 'Pricing'
);
private static $summary_fields = array (
    'PlanName' => 'Name of Plan',
    'PlanPrice' => 'Price',
    'PlanRenewal' => 'Renewal Period',
);
public function getCMSFields() {
    $fields = FieldList::create(
        TextField::create('PlanName'),
        TextField::create('PlanRenewal'),
        TextField::create('PlanPrice'),
        TextField::create('PlanColor')
    );
    return $fields;
}

public function getServicePlans() {
    return $this->Pricing();
}

HomePage.php

class Pricing extends Page {
private static $has_many = array (
    'ServicePlans' => 'ServicePlan',
);

public function getCMSFields() {
    $fields = parent::getCMSFields();


    $fields->addFieldsToTab('Root.Plans', GridField::create(
        'ServicePlans',
        'Orenda Force Service Plan Information',
        $this->ServicePlans(),
        GridFieldConfig_RecordEditor::create()
    ));

    return $fields;
    }
}

class Pricing_Controller extends Page_Controller {

}

布局/ HomePage.ss

class HomePage extends Page {
}

class HomePage_Controller extends Page_Controller {
    public function ServiceTeasers($count = 2) {
        $holder = ServicesHolder::get()->First();
        return ($holder) ? ServicesPage::get()->limit($count) : false;
    }

    public function MembershipPlans() {
        $Pricing = Pricing::get();
        return $plan;
    }
}

我在访问内容时没有问题

布局/ Pricing.ss

...//

<% loop $MembershipPlans %>
    <div class="col-1-3 card pricing">
        <div class="pricing__header  primary $PlanColor">
            <p class="pricing__plan-name">$PlanName</p>
            <p class="pricing__price">$PlanPrice<sub>$PlanRenewal</sub></p>
        </div>
        <div class="card__contents">
            <h3 class="title-06">Plan details</h3>
            <ul>
                <li>unlimited training</li>
                <li>individual nutrition/meal plans</li>
            </ul>
        </div>
    </div>
    $Content
<% end_loop %>

...//

我非常感谢你们所能提供的任何帮助，我一直试图解决这个问题几天，而且我一次又一次地碰壁砖。我做错了什么？

This question是我得到的最接近的，似乎没有解决我的问题。我应该将<section class="body pricing"> <div class="content"> <h2 class="title-02 text-monochrome">Pricing</h2> <% loop $ServicePlans %> <div class="col-1-3 card pricing"> <div class="pricing__header $PlanColor"> <p class="pricing__plan-name">$PlanName</p> <p class="pricing__price">$PlanPrice<sub>$PlanRenewal</sub></p> </div> <div class="card__contents"> <h3 class="title-06">Plan details</h3> <ul> <li>unlimited training</li> <li>individual nutrition/meal plans</li> </ul> </div> </div> <% end_loop %> </div> </section>移到FieldList页吗？

Answer 1

对于您的主页，您似乎已经拥有了大部分内容。您只是错过了Price页面所具有的has_many的循环。由于MembershipPlans()中的HomePage_Controller函数会将所有价格页面作为DataList返回，因此您可以通过循环关系名称来访问相关对象，在本例中为<% loop $ServicePlans %>。

<强> HomePage.ss

<% loop $MembershipPlans %><!-- loop Price pages -->
<% loop $ServicePlans %><!-- this is your loop for the ServicePlans related to the particular Price page -->
<div class="col-1-3 card pricing">
    <div class="pricing__header  primary $PlanColor">
        <p class="pricing__plan-name">$PlanName</p>
        <p class="pricing__price">$PlanPrice<sub>$PlanRenewal</sub></p>
    </div>
    <div class="card__contents">
        <h3 class="title-06">Plan details</h3>
        <ul>
            <li>unlimited training</li>
            <li>individual nutrition/meal plans</li>
        </ul>
    </div>
</div>
<% end_loop %><!-- end ServicePlans relation loop -->
$Content<!-- Content for particular Price page -->
<% end_loop %><!-- end Price pages loop -->

Silverstripe从单独的页面类型访问has_many数据
