Custom price attribute - how to add global price format and attribute label in frontend?

[cojone]

Hello,

I've added a custom price attribute called "rrp" in magento 2.1, which i like to show on frontends category- and product-page.

But in frontend, price is shown with 4 decimals, for example 10.0000 instead 10.00, and without currency symbol and without attribute label.

code i've used to show the attribute value:

<?php /* @escapeNotVerified */ echo $_helper->productAttribute($_product, $_product->getRrp(), 'rrp') ?>

to show attribute label also, i've tried following code, but this doesn't work: 

<?php /* @escapeNotVerified */ echo $_helper->productAttribute($_product, $_product->getRrp(), 'rrp'); $_product->getResource()->getAttribute('rrp')->getStoreLabel() ?>

How i could add global currency format to the attribute?
And how i could add the attribute label?

Thanks a lot for your help and have a good day!

Hi,

on the product page the fastest way should be using pricing helper to format the price:

<?php $pricingHelper = $this->helper(\Magento\Framework\Pricing\Helper\Data::class); ?>
<?php echo $pricingHelper->currency($_product->getData('rrp'), true, false); ?>

For the attribute label, there's an echo statement missing in your code, so the attribute label is retrieved, but not displayed:

<?php echo $_product->getResource()->getAttribute('rrp')->getStoreLabel(); ?>

Cheers,

Hi @cojone

I was looking for some built-in helper that could be used for this purpose, but I didn't find any. Actually, there's Magento\Customer\Helper\Session\CurrentCustomer class, but it doesn't inherit from AbstractHelper, so it cannot be easily called in the template. Therefore it seems that you have to create own helper to achieve your goal.

I assume that you are able to create a basic Magento 2 module structure containing valid module.xml and registration.php files, otherwise let me know, I will provide you with the content of those files. Let's call our module MyVendor_MyModule and let's assume it resides in app/code/MyVendor/MyModule directory.

Next create a new helper class in app/code/MyVendor/MyModule/Helper/Customer.php file with the following content:

<?php

namespace MyVendor\MyModule\Helper;

class Customer extends \Magento\Framework\App\Helper\AbstractHelper
{
    /**
     * @var \Magento\Customer\Model\Session
     */
    protected $customerSession;

    public function __construct(\Magento\Customer\Model\Session $customerSession)
    {
        $this->customerSession = $customerSession;
    }

    public function isCurrentCustomerRetailer()
    {
        // instead of 3 you can put any customer group ID
        return $this->customerSession->getCustomerGroupId() == 3;
    }
}

In the template file use following condition to decide whether to display your custom price attribute or not:

<?php $pricingHelper = $this->helper(\Magento\Framework\Pricing\Helper\Data::class); ?>
<?php $customerHelper = $this->helper(\MyVendor\MyModule\Helper\Customer::class); ?>
<?php if ($customerHelper->isCurrentCustomerRetailer()): ?>
    <?php echo $_product->getResource()->getAttribute('rrp')->getStoreLabel(); ?>
    <?php echo $pricingHelper->currency($_product->getData('rrp'), true, false); ?>
<?php endif; ?>

You may also need to enable your module and run upgrade scripts from the console:

$ bin/magento module:enable MyVendor_MyModule
$ bin/magento setup:upgrade
$ bin/magento cache:clean

Hope this helps.

Cheers,

Hello,

Thank you so much for your help!

But sadely, i can't bring it to work till now... I think i've did something wrong, but i can't find my mistake(s)...

I've added customer.php and template code as you described.

Then i've added a registration.php with following code, saved in app/code/MyVendor/MyModule/

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
	\Magento\Framework\Component\ComponentRegistrar::MODULE,
	'MyVendor_MyModule',
	__DIR__
);

after, i've created module.xml with following code, saved in app/code/MyVendor/MyModule/etc/

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="MyVendor_MyModule" setup_version="2.1.3" />
</config>

then i've created composer.json with following code, saved in vendor/myvendor/mymodule/

{
  "name": "myvendor/mymodule",
  "description": "Module für UVP Kundengruppe Händler",
  "require": {
    "magento/magento-composer-installer": "*"
  },
  "type": "magento2-module",
  "version": "0.0.1",
  "autoload": {
    "files": [ "registration.php" ],
      "psr-4": {
        "MyVendor\\MyModule\\": ""
    }
  }
}

and then i've added second part of following code in root/composer.json to "repositories"

"repositories": [
        {
            "type": "composer",
            "url": "https://repo.magento.com/"
        },
		{
            "type": "vcs",
            "url": "/app/code/MyVendor/MyModule"
        }
    ],

i think i've did something wrong in this files, but i can't find where...
when i try to enable module and run upgrade scripts i got some failed message...
Do you have an idea what i've did wrong?

Thank you very much for your help and greetings

Hi @cojone

for the modules residing in app/code directory, you don't have to bother with composer configuration, modules from this directory are automatically registered and recognized by autoloader. Just make sure you follow the naming conventions, i.e. if you put your code under app/code in MyVendor/MyModule directory, your namespaces should start with MyVendor\MyModule, if you use MyVendor\MyModule\Helper\Customer helper, its class can be found in app/code/MyVendor/MyModule/Helper/Customer.php file (note, that everything is case-sensitive).

I believe it's enough for you to rollback all changes you did to the global composer.json, because your module.xml and registration.php files look ok for me.

I would also delete the custom composer.json from vendor/myvendor/mymodule directory, but I guess it doesn't really matter.
