Magento2 terms and condition in popup with cms block not working

Question

I have Magento 2.2.3 and activated terms and conditions. And I added

{{block class="Magento\\Cms\\Block\\Block" area='frontend' block_id="agb"}} {{block class="Magento\\Cms\\Block\\Block" block_id="agb"}}

but in popup no text is shown, only above code is shown. Anyone an idea what is wrong? I use same snippet in other shop and it is working

Thanks! Martin enter image description here

• Hitesh Koshti: Have you added static block in phtml file or CMS page ?
• matin: yes - and it is active

Answer 1

The agreements are rendered via knockout js, therefore you cannot add a cms block to their content, you could go and extend the agreements module to process the data before sending it to the frontend via knockout, but i would just turn things around.

Don't include a cms block inside the agreements, but include the agreements in your cms page as follows:

use the Layout/design update xml field for the cms page with something like the following:

<referenceContainer name="content">
 <block class="Magento\CheckoutAgreements\Block\Agreements" name="agb.agreement" template="Vendor_Module::html/agreements/agb.phtml" after="-" />
</referenceContainer>

and the corresponding template to insert exactly the one agreement you want:

<?php
/**
 * @var $block \Magento\CheckoutAgreements\Block\Agreements
 */
/**
 * Define agreement for display
 *
 * Copy this template if you wish to insert an agreements static content somewhere
 *
 * @var $display_agreement string - Agreement id or name
 */
$display_agreement = 'AGB';
/**
 * Process
 */
$was_found = false;
foreach ($block->getAgreements() as $agreement) {
 // Found requested agreement
 if ($agreement->getId() == $display_agreement || $agreement->getName() == $display_agreement) {
 $was_found = true;
 print '<div class="agreement_content">';
 if ($agreement->getIsHtml()) {
 /* @escapeNotVerified */
 print $agreement->getContent();
 } else {
 print nl2br($block->escapeHtml($agreement->getContent()));
 }
 print '</div>';
 }
}
if (!$was_found) {
 throw new Exception('Agreement display failed, could not find: ' + $display_agreement);
}

You can find some more info on the agreements block here: Why does getAgreements() return nothing?

Answer 2

agreement content is load from class Magento\CheckoutAgreements\Model\AgreementsConfigProvider protected function getAgreementsConfig()

'content' => $agreement->getIsHtml()
 ? $agreement->getContent()
 : nl2br($this->escaper->escapeHtml($agreement->getContent()))

could override using preference

use below function to get cms block content

/** @var \Magento\Framework\View\LayoutInterface */
protected $_layout;
public function __construct(\Magento\Framework\View\LayoutInterface $layout)
{
 $this->_layout = $layout;
}
public function getContent()
{
 $cmsBlockId = 1; // id of cms block to use
 return $this->_layout->createBlock('Magento\Cms\Block\Block')->setBlockId($cmsBlockId)->toHtml();
}

• TheFrakes: Can you specify which files to edit and where to put them to avoid core overrides?
