I am able to set and get config data in a field under General table with the test code. The Magento backend displays the field as the screenshot below shows. The issue is this field is blank, but supposed to display the value from the table. Please help me find what is missing in the field.
system.xml is as follows:
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
<system>
<section id="pmm" translate="label" type="text" sortOrder="330" showInDefault="1" showInWebsite="1" showInStore="1">
<label>PMM</label>
<tab>general</tab>
<resource>Magento_Config::pmm</resource>
<group id="currency_conversion" translate="label" type="text" sortOrder="1100" showInDefault="1" showInWebsite="1" showInStore="1">
<label>Currency Conversion</label>
<field id="usd_to_cad_conversion" translate="label" type="select" sortOrder="120" showInDefault="1" showInWebsite="1" showInStore="0" canRestore="1">
<label>USD to CAD Exchange Rate</label> <!-- Custom label -->
</field>
</group>
</section>
</system>
</config>
my module.xml is as follows:
<?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="Perfectmakeupmirrors_CustomShipping" >
<sequence>
<module name="Magento_Store"/>
<module name="Magento_Sales"/>
<module name="Magento_Quote"/>
<module name="Magento_SalesRule"/>
<module name="Magento_Backend"/>
</sequence>
</module>
</config>
Finally, the test code written to set and get the config data is below:
<?php
/*

* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
// Initial code to Bootstrap Magento 2
use MagentoFrameworkAppBootstrap;
use public_htmltestcodeWriteconfig;
include('app/bootstrap.php');
$bootstrap = Bootstrap::create(BP, $_SERVER); // Magento gets initialized at this point
$objectManager = $bootstrap->getObjectManager();
// Object to get the current store time in PST
$timezone = $objectManager->get('MagentoFrameworkStdlibDateTimeTimezoneInterface');
$state = $objectManager->get('MagentoFrameworkAppState');
$state->setAreaCode('frontend');
// Initial code to Bootstrap Magento 2 ends here
/************t*************************************************************************************/
$date = $timezone->date();
// If one needs to diplay date in the formate of Ymd use 'Ymd'
$current_store_time = $date->format('Ymd H:i:s');
echo "<body>";
echo "**********************************************Magento Store Time : " . $current_store_time . "**********************************<br><br>";
// Instantiate class Write_Read_Config.
// Call function to set config data.
// Call function to get config data and display.
$configWriter = $objectManager->get('MagentoFrameworkAppConfigStorageWriterInterface');
$storeManager = $objectManager->get('MagentoStoreModelStoreManagerInterface');
$scopeConfig = $objectManager->get('MagentoFrameworkAppConfigScopeConfigInterface');
//for all websites
$websites = $storeManager->getWebsites();
$scope = "websites";
$value = 1.26;
foreach($websites as $website) {
echo $website->getId() . "<br>";
// Set config data.
$configWriter->save("/pmm/currency_conversion/usd_to_cad_conversion", $value, $scope, $website->getId());
}
// Display Config data.
echo "Current USD to CAD exchange rate is " . $scopeConfig->getValue("/pmm/currency_conversion/usd_to_cad_conversion", "websites");
echo "</body>";
