Hello Axel

This will be forwarded to our development team, but at the moment there's nothing we can do about it.

The current time is generated by the placeholder when you open the modal, and if you keep the modal open for a longer period of time it will stay like that. wpDataTables can't yet generate the time in real-time.

Like I said, this will be forwarded to our developers, and hopefully they'll be able to do something about it in one of our future updates.

I understand, Axel.

That's how the plugin works at the moment, unfortunately. Our developer checked this, and said that he's going to create a task to resolve this issue. We'll either refresh it when the modal opens up, or something like that.

The issue is acknowledged and it will be resolved in the future.

Thank you, Axel, for sharing that with everyone.

Our developers are aware of this issue, and they will work on it in the future.

Hello again Axel

Not yet. Our developers added this as a task for the future, but I can't say when it will be fixed. At the moment, your workaround is the best option there is.

Please feel free to add it as a feature suggestion on  this page, also.

Hello  Axel,

Sorry for the delay in our responses, has been national holidays in our country for the last two days.

Aleksandar is on vacation and I will help you out.

Yes, that is a bug and it is forward to our developers. That value for current_datetime is created to replace current DateTime when you insert new data (open edit modal) it is not live DateTime counter that will replace value like in your case, it is just the current date-time value in the moment when you open edit modal(that placeholder is replaced with that value)

What you can do as a workaround

function timestamp_for_wpdatatables ( $formdata, $tableId ) {   
    $columnsData = WDTConfigController::loadColumnsFromDB($tableId);
      foreach ($columnsData as $column) {
          if ($column->orig_header == "timestamp") {
                  $formdata["timestamp"] = date("Y-m-d H:i:s");
          } elseif ($column->orig_header == "created" && get_query_var('new_created_for_wpdatatables') == true) {
                 $formdata["created"] = date("Y-m-d H:i:s");
          }
     }
         return $formdata;
 } 
add_filter('wpdatatables_filter_formdata_before_save', 'timestamp_for_wpdatatables',10,2);
function created_for_wpdatatables ( $formdata, $tableId ) {
    if ($formdata['wdt_ID'] == '') {
         set_query_var('new_created_for_wpdatatables', true);
     }
     return $formdata;
 } 
add_filter('wpdatatables_filter_frontend_formdata', 'created_for_wpdatatables',10,2);

This can auto-increment DateTime into columns with headers "timestamp" or "created"

Best regards

Hello  Axel,

Sorry for the late response. 

We are located in Serbia and our working time is from 10:00 to 17:00 CET. business days.

Yes, your origin header have to be the same as those values or you can change those values in the hook how is called in your database.

For example, if you have a column in the database that is called timeValue and updateDate nad like datae is shown as origin headers in the column settings then you will use

function timestamp_for_wpdatatables ( $formdata, $tableId ) {   
    $columnsData = WDTConfigController::loadColumnsFromDB($tableId);
      foreach ($columnsData as $column) {
          if ($column->orig_header == "timeValue") {
                  $formdata["timeValue"] = date("Y-m-d H:i:s");
          } elseif ($column->orig_header == "updateDate" && get_query_var('new_created_for_wpdatatables') == true) {
                 $formdata["updateDate"] = date("Y-m-d H:i:s");
          }
     }
         return $formdata;
 } 
add_filter('wpdatatables_filter_formdata_before_save', 'timestamp_for_wpdatatables',10,2);
function created_for_wpdatatables ( $formdata, $tableId ) {
    if ($formdata['wdt_ID'] == '') {
         set_query_var('new_created_for_wpdatatables', true);
     }
     return $formdata;
 } 
add_filter('wpdatatables_filter_frontend_formdata', 'created_for_wpdatatables',10,2);

Please note that updateDate will be formatted as DateTime value only for new entries. if the user edits those fields and remove value from this column(leave empty) it will be empty. If you need like for timeValue you will need to remove  get_query_var from the condition.

These hooks are triggered only when you are editing or adding new entries.
