set Error message content from the static blocks magento2

Question

I am setting error message using below code.

$this->_messageManager->addError(__('you must login to continue.'));

Is it possible to load the message from the static block content.

for example i created static block with some html content. that content i need to show in error message. Is that can be done?

Answer 1

you need to try this code.

For phtml file you need to used this code.

<?php 
$customerror = $block->getLayout()->createBlock('Magento\Cms\Block\Block')->setBlockId('block_identifier')->toHtml();
$this->_messageManager->addError(__($customerror));
?>

For block file you need to do code like this.

class Yourclass
{
    protected $cmsblock;

    public function __construct(\Magento\Cms\Block\Block $cmsblock)
    {
       $this->cmsblock = $cmsblock;
    }

    public function Yourfunction()
    {
      $customerror = $this->cmsblock->setBlockId('block_identifier')->toHtml();
      $this->_messageManager->addError(__($customerror));
    }
}

Replace 'block_identifier' with your block identifier.
