Add new tab under system configuration in magento

In the last post I have showed , how to add new Tab in Magento admin panel. Now in this post I will add new Tab under System->Configuration.To add so, You need to create a new module. Click here to create an admin Module then make some changes which is written here.

Create a system.xml file inside etc folder of your module, Then write the following code to add a tab

 
<?xml version="1.0"?>
<config>
    <tabs>
        <systab translate="label" module="systab">
            <label>System Configuration Tab</label>
            <sort_order>200</sort_order>
        </systab>
    </tabs>
    <sections>
        <systab translate="label" module="systab">
            <class>separator-top</class>
            <label>My system Configuration Tab</label>
            <tab>systab</tab>
            <sort_order>100</sort_order>
            <show_in_default>1</show_in_default>
            <show_in_website>1</show_in_website>
            <show_in_store>1</show_in_store>
            <groups>
                <systab_option translate="label">
                    <label>sysem Tab Options</label>
                    <frontend_type>text</frontend_type>
                    <sort_order>10</sort_order>
                    <show_in_default>1</show_in_default>
                    <show_in_website>1</show_in_website>
                    <show_in_store>1</show_in_store>
                    <fields>
   <registration_mode translate="label">              <label>On New User Signup</label>
                            <frontend_type>select</frontend_type>
                            <source_model>adminhtml/system_config_source_yesno</source_model>
                            <sort_order>1</sort_order>
                            <show_in_default>1</show_in_default>
                            <show_in_website>1</show_in_website>
                            <show_in_store>1</show_in_store>
                        </registration_mode>
   <forget_mode translate="label">
                            <label>Send Email on Forget Password</label>
                            <frontend_type>select</frontend_type>
                            <source_model>adminhtml/system_config_source_yesno</source_model>
                            <sort_order>1</sort_order>
                            <show_in_default>1</show_in_default>
                            <show_in_website>1</show_in_website>
                            <show_in_store>1</show_in_store>
                        </forget_mode>
   <purchase_mode translate="label">
                            <label>Send Email On Product Purchase</label>
                            <frontend_type>select</frontend_type>
                            <source_model>adminhtml/system_config_source_yesno</source_model>
                            <sort_order>1</sort_order>
                            <show_in_default>1</show_in_default>
                            <show_in_website>1</show_in_website>
                            <show_in_store>1</show_in_store>
                        </purchase_mode>
                    </fields>
  </systab_option>
            </groups>
        </systab>
    </sections>
</config>

Now important things which needs to do. Go to your System->Cache Management then clear your all cache. Now go to System->Permissions->Roles. Click on Administrators, from Role Resources Tab select Resource Access All from the drop down and save. Now go to System ->Configuration .You can see a new tab has added in the left side.
