Magento 2.4 – Customize PayPal Smart Button Style

checkoutmagento2modulepaypalPHP

I want to change the button style of the PayPal Express Checkout, but is not work, I have create a module to rewrite the PayPal but how I can add my changes there?

I create di.xml file on following location

app\code\Vendor\Extension\etc\frontend\di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="\Magento\Paypal\Model\SmartButtonConfig" type="Vendor\Extension\Model\SmartButtonConfig" />
</config>

create SmartButtonConfig.php on following location

app\code\Vendor\Extension\Model\SmartButtonConfig.php

namespace Vendor\Extension\Model;

class SmartButtonConfig extends \Magento\Paypal\Model\SmartButtonConfig
{
   //do the code
}

and I have this function:

Public function:

private function getButtonStyles(string $page): array
{
    $styles = $this->defaultStyles[$page];
    if ((boolean)$this->config->getValue("{$page}_page_button_customize")) {
        $styles['layout'] = $this->config->getValue("{$page}_page_button_layout");
        $styles['size'] = $this->config->getValue("{$page}_page_button_size");
        $styles['color'] = $this->config->getValue("{$page}_page_button_color");
        $styles['shape'] = $this->config->getValue("{$page}_page_button_shape");
        $styles['label'] = $this->config->getValue("{$page}_page_button_label");
        $styles = $this->updateStyles($styles, $page);
    }
    return $styles;
}

I want to add only this, this are my changes:

$styles['height'] = 55;
$styles['tagline'] = false;
$styles['fundingicons'] = false;

in the private function getButtonStyles

so what I want to do is to not overwrite the vendor file. so this function private function getButtonStyles exist already in the vendor/magento/module-paypal/Model/SmartButtonConfig.php,

I just want to add in this function

$styles['height'] = 55;
$styles['tagline'] = false;
$styles['fundingicons'] = false;

and to be in a seperate module, because I don't want to lose the modifications when I'll upgrade the store .

Thank you

No need to create preference, we can use type

create:

app/code/Vendor/Extension/etc/di.xml

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\Paypal\Model\SmartButtonConfig">
        <arguments>
            <argument name="defaultStyles" xsi:type="array">
                <item name="checkout" xsi:type="array">
                    <item name="height" xsi:type="number">55</item>
                    <item name="tagline" xsi:type="boolean">false</item>
                    <item name="fundingicons" xsi:type="boolean">false</item>
                </item>
                <item name="cart" xsi:type="array">
                    <item name="height" xsi:type="number">55</item>
                    <item name="tagline" xsi:type="boolean">false</item>
                    <item name="fundingicons" xsi:type="boolean">false</item>
                </item>
                <item name="mini_cart" xsi:type="array">
                    <item name="height" xsi:type="number">55</item>
                    <item name="tagline" xsi:type="boolean">false</item>
                    <item name="fundingicons" xsi:type="boolean">false</item>
                </item>
                <item name="product" xsi:type="array">
                    <item name="height" xsi:type="number">55</item>
                    <item name="tagline" xsi:type="boolean">false</item>
                    <item name="fundingicons" xsi:type="boolean">false</item>
                </item>
            </argument>
        </arguments>
    </type>
</config>

Note: you can remove any node if don't require (i.e.checkout,cart,mini_cart,product)

Magento2 Module – Fix ‘main.CRITICAL: Plugin Class Doesn’t Exist’

I couldn't reproduce your error, but I got an other one.

Then I did some minor adjustments to your code and it worked.
First drop the InstallSchema.php file. It does nothing so it is useless.

Then make sure that your plugin file is in Amaj/CorePlugin/Model/Currency/Plugin.php and it looks like this:

<?php

namespace Amaj\CorePlugin\Model\Currency;

class Plugin
{
    protected $logger;

    public function __construct(\Psr\Log\LoggerInterface $logger) {
        $this->logger = $logger;
    }

    /**
     * @param $subject
     * @param \Closure $proceed
     * @param $price
     * @param array $options
     * @return string
     */
    public function aroundFormatTxt(
        $subject,
        \Closure $proceed,
        $price,
        $options = []
    )
    {
        $this->logger->info('Amaj aroundFormatTxt');
        return '2';
    }

}

you don't need parent::__construct(); in the constructor because there is no parent class.
And I replaced $logger->info with $this->logger->info because there is no $logger variable.

Magento – How to override private function in Model (Magento-2)

Private functions cannot overridden in child class.

If you want to change the logic in _validate function you can use below method.

Override save function, inside that instead of calling $this->_validate($addressModel) function use your own custom function, like below

private function _validateCustom(CustomerAddressModel $customerAddressModel) {
//your custom validation logic
}

Change the di.xml into

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">   
    <preference for="Magento\Customer\Api\AddressRepositoryInterface" type="Maha\CreateLastname\Model\ResourceModel\AddressRepository" />
</config>

Because in the AccountManagement.php they injected AddressRepositoryInterface in __constructor.

You can achieve this by using plugin as well and that is recommended way.
