How to add a custom block in Magento 2 System Configuration Group?

Question

I am trying to add a text block in Magento 2 system configuration group.
I want to write some hints for the users in a separate group. As it can be done in Magento 1.

Here is my screenshot what I actually want.

Magento 1.x System Configuration Group's Block

Still, I am waiting for any response. Is there anyone who has done this before in Magento 2?
Please let me know about this.

Thanks in Advance.

Answer 1

You can use the <frontend_model> feature of system configuration. here is the example

 <field id="YOUR_NAME" showInDefault="1" showInWebsite="1" showInStore="1" sortOrder="100">
 <frontend_model>VENDOR\MODULE_NAME\Block\Adminhtml\System\Config\Advanced</frontend_model>
 <attribute type="shared">1</attribute>
 </field>

and your block file should contain this code

<?php
namespace VENDOR\MODULE_NAME\Block\Adminhtml\System\Config;
class Advanced extends \Magento\Config\Block\System\Config\Form\Field
{
 /**
 * Template path
 *
 * @var string
 */
 protected $_template = 'system/config/advance/YOUR_FILE.phtml';
 /**
 * Render fieldset html
 *
 * @param \Magento\Framework\Data\Form\Element\AbstractElement $element
 * @return string
 */
 public function render(\Magento\Framework\Data\Form\Element\AbstractElement $element)
 {
 $columns = $this->getRequest()->getParam('website') || $this->getRequest()->getParam('store') ? 5 : 4;
 return $this->_decorateRowHtml($element, "<td colspan='{$columns}'>" . $this->toHtml() . '</td>');
 }
}

And in your view\adminhtml\templates\system\config\advance\YOUR_FILE.phtml file you can write anything which you want

<div>
<?php echo __('Hello WOrld'); ?>
</div>

• Gaurav Agrawal: Can you tell me where to keep this phtml file.
• Keyur Shah: view\adminhtml\templates\system\config\advance\YOUR_FILE.phtml
• Keyur Shah: Any reason @GauravAgrawal :)
• Gaurav Agrawal: Hey Keyur, I am not able to check your answer after implementation. because of some access issue. So whenever I will check and complete it. Will update here.
• Gaurav Agrawal: Hey Keyur, I have tried your solution today. And it not worked for me. It shows a black page after adding code provided by you.
