• Learing_Coder: You have to create config.xml also To show that @Ajay Patel
• Ajay Patel: can you please guide me how to do this?
• Ajay Patel: I think config.xml its for set default value set. not require to create tab and config field.

Answer 1

You have to Put these code in system.xml

file path:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
 <system>
 <tab id="dd_invoice" translate="label" sortOrder="10">
 <label>Ewall</label>
 </tab>
 </system>
</config>

then You have to create config.xml

file Path:app/code/Extension/Module/etc/config.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Store:etc/config.xsd">
 <default>
 <dd_invoice>
 <general>
 <enable>1</enable>
 <time_insec>5</time_insec>
 </general>
 </dd_invoice>
 </default>
</config>

• Ajay Patel: what is time_insec??
• Learing_Coder: Those are my fields In tab..You can give your tab fields @AjayPatel
• Ajay Patel: sorry dude this not work for me.
• Learing_Coder: Chnage Sort order Once @AjayPatel
• Ajay Patel: ohh... my site is down with this error : Warning: Invalid argument supplied for foreach() in

Answer 2

You should see:

The system.xml is a configuration file which is used to create configuration fields in Magento 2 System Configuration. You will need this if your module has some settings which the admin needs to set. You can go to Store -> Setting -> Configuration to check how it look like.

Answer 3

Create Sections In Order to Display. If there are no sections it wont be visible in Configuration

Try this code

<?xml version="1.0" encoding="UTF-8"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
 <system>
 <tab id="DDD" translate="label" sortOrder="20">
 <label>DDD</label>
 </tab>
 <section id="mymodule" translate="label" sortOrder="20" type="text" showInDefault="1" showInWebsite="1" showInStore="1">
 <class>separator-top</class>
 <label>My Module</label>
 <tab>DDD</tab>
 <resource>Namespace_Modulename::config_mymodule</resource>
 <group id="general" translate="label" sortOrder="1" type="text" showInDefault="1" showInWebsite="1" showInStore="1">
 <label>General Configuration</label>
 <field id="active" translate="label comment" sortOrder="20" type="select" showInDefault="1" showInWebsite="1" showInStore="1">
 <label>Enable My Module</label>
 <source_model>Magento\Config\Model\Config\Source\Yesno</source_model>
 </field>
 </group>
 </section> 
 </system>
</config>

Update

Add the acl file in

yourmodulepath/etc/acl.xml

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Acl/etc/acl.xsd">
 <acl>
 <resources>
 <resource id="Magento_Backend::admin">
 <resource id="Magento_Backend::stores">
 <resource id="Magento_Backend::stores_settings">
 <resource id="Magento_Config::config">
 <resource id="Namespace_Modulename::config_mymodule" title="My Module"/>
 </resource>
 </resource>
 </resource>
 </resource>
 </resources>
 </acl>
</config>

• Ajay Patel: No luck with this sorry
• Priyank: Have you tried clearing cache? What error are you getting ?
• Ajay Patel: Warning: Invalid argument supplied for foreach() in
• Priyank: I assume the error is coming from somewhere else. This code works for me.
• Ajay Patel: what is this config_mymodule?
