Hi joy007,
welcome!
You must use the action-Tag in the form-Element like this
Code:
<form id="your_unique_ID" name="your_unique_NAME" action="plugin.php?kPlugin={$oPlugin->kPlugin}&cPluginTab=THIS_IS_THE_NAME_FROM_REGISTER" method="post">
and in the form
Code:
<input type="hidden" name="kPlugin" value="{$oPlugin->kPlugin}">
in the info.xml it looks like:
Code:
<Customlink sort="98">
<Name>THIS_IS_THE_NAME_FROM_REGISTER</Name>
<Filename>your_php_file.php</Filename>
</Customlink>
Thank you @ ag-websolutions.from,
I like to tell you my query in details.
I've developed one plugin version "1.00" and uploaded to the
shop and it's working fine.

Later I've upgraded my module to "1.10".

When I click on update button getting one confirmation message "Wollen Sie das Plugin for real to update? ". I clicked on " ok " button then my module is updating and I am getting success message "Ihr Plugin has been successful Service." On the same "Plugin Administration" page and everything is working fine.
BUT my expectation is when I click on "ok" button it should update the plugin as it is and after update process, it should redirect to my plugin setting page instead of displaying success message "Ihr Plugin has been successful Service." on the same page.

So kindly help me to achieve my expected result in the update process if it's possible and if it's not then also plz tell me.
