getConfigData

[ttnnkkrr]

i want to call 

getConfigData('some key from my payment config')

I want to do this in a controller file

I cannot for the life of me figure out what classes to instantiate to get to it 

[AJAX ZOOM · Accepted solution]

1) create the helper Helper/Data.php for example 

<?php
namespace [Vendor]\[ModuleName]\Helper;

class Data extends \Magento\Framework\App\Helper\AbstractHelper
{
    public function getConfig($config_path)
    {
        return $this->scopeConfig->getValue(
            $config_path,
            \Magento\Store\Model\ScopeInterface::SCOPE_STORE
        );
    }
}

2) then in the controller you can use

$config = $this->_objectManager->get('[Vendor]\[ModuleName]\Helper\Data')->getConfig('[ConfigPath]');

It may be there is easiest way but it works fine for me

Hi,

Below are the steps to call getConfigData value.

1. Create Helper/Data.php file

namespace [Vendor]\[ModuleName]\Helper;

class Data extends \Magento\Framework\App\Helper\AbstractHelper
{
    public function getConfig($config_path)
    {
        return $this->scopeConfig->getValue(
            $config_path,
            \Magento\Store\Model\ScopeInterface::SCOPE_STORE
        );
    }
}

2. Using the following function you can call the store config value on front end.

 echo $this->getConfig('section_id/group_id/field_id');

You sir are a refreshing change. You provided a Concise even if not exhaustive answer. I was asking  what should have been a simple question and as usual to what i have seen on this board i got 

1. one answer that probably should in theory have worked
2. one perhaps exhaustive answer to something i wasn't really asking.

The surprise here!!!

1. Your answer which was exactly what i was hoping for. a couple targeted lines of code that was complete and addressed my specific question

I am unsure why every simple thing a dev could want to do seems to get answers that require 5 gaggillion different files and millions of lines of code. I hope you continue to demonstrate how to answer forum posts. You see, since you gave me a concise answer. I am able to build upon it in a constructive way. You also succeeded in the "teach a man to fish" philosophy
