Hi Lowell,

1. Yes, each licence has unlimited subdomains, and sub-sites available for activation.

So if they are on the same domain - you can activate the same licence on both.

You can switch between Domains for the activation, for example, if you move the data from Staging to a Live/production version Site, and vice-versa, but a Standard licence can't be active on two domains at the same time.

If you need more domains to be activated at same time, you can upgrade to a Pro licence or higher.

-

But I also wish to advise that you are not obligated to have Staging Site activated on your licence.

For any Staging/Test/Development or localHost Site, you can manually install and update the Plugin by downloading the latest installation from your TMS Store Account.

We recommend to only keep activated licence for your Live/production version of the Site.

If you need to deactivate one domain/ and activate another :

1. If you have access to the 'old domain', just log in the WP-Admin there, go in our Plugin settings/Activation and hit 'deactivate licence' button.

After that, go to the 'new domain' and there in our Plugin Activation Settings simply paste your Purchase Code and activate the new site.

2. Or you can deactivate through the TMS Store account. Log in, find "My licences" , and on the licence in the "Manage domains", there you can deactivate currently active domain, and log in the new Domain Wp-Admin, our Activation settings and activate the plugin there.

You can also compare the features between all Plans from Lite(free), then Premium versions from the Starter all the way up to the Developer Level, in the Plugin back-end Dashboard, under "Lite vs Premium".

You can also see this on the pricing Page, but here in the Dashboard, we show more details about each specific feature, etc.

If you don't have any installation now on your WordPress, you can easily see this on our Demo Sandbox Website.

2. I would like to know if it possible to send an email notification to a specific user when 1. A new data is add in the table and 2 when change a status (example I will have a status column)

We don't have a built-in feature to send Emails from our Plugin (yet).

You can make a future development suggestion for a native option.

Please feel free to search on our suggestions page, 

 to see if someone may be already suggested this feature. If you can't see it, feel free to add your suggestion there,  and as more people vote, the feature will move higher on the priority list.

You can certainly follow our changeLog page if you'd like ( it is also available in the plugin dashboard), where we state any changes/new features/bug fixes during updates;

and our newsletter, so you're informed about new features, bug fixes, freebies, etc.

If you have coding skills to try a custom solution, the only 'as close as possible' example i have is this.

It was for a user who wanted to 'send an Email' with any edited Row;

As soon as it is edited - the Email would get send.

-

For sending emails, you can use this:

https://www.a2hosting.com/kb/installable-applications/optimization-and-configuration/wordpress2/sending-e-mail-in-wordpress#:~:text=To%20send%20an%20e%2Dmail,authentication%20settings%20you%20defined%20above

And to take values after Apply is hit, there's this hook:

wpdatatables_after_frontent_edit_row( $formdata, $rowId, $tableId ) This action is executed after editing action is applied.

$formdata is the array of keys and values for editing.

$rowId is the ID field of the row in MySQL table that was edited.

$tableId is the table identifier from the MySQL plugin table (wp_wpdatatables).

For example:

function sendEmailAfterEdit( $formdata, $rowId, $tableId ){ // create logic for sending emails } add_action('wpdatatables_after_frontent_edit_row', 'sendEmailAfterEdit',10,3);

will be triggered in both cases when you edit or adding a new row in the table from front-end. Please note that data is already saved in database.

-

Please note, our Support does not cover Custom solutions, we can just share some examples, i hope this helps as a 'starting point' if you have coding skills or your own developer to try a custom solution.

And i just wanted to point out that you can try wpDataTables before purchasing

 on our sandbox Demo sites ( you can find links for the main plugin Demo,  

as well as add-on Demos, in my signature),

and there is a 15-day money-back guarantee period, 

so if you purchase the plugin, you can safely fully test it out, and if it doesn't fit your needs you can request and receive a refund in that period. ( same goes for all plugins and add-ons)

Let me know if you have any additional questions.
