Question on hiding buttons in Version 10.91

"Clock In" and "Clock Out" are custom buttons. Go to designer ann press the first button. In button properties you'll see the item id, next to rename there is a question mark "?". Click it and you see a help text. there is somthing like this
For elements in the data grid on the List and Print pages use $recordId parameter in the After record processed event:
$pageObject->hideItem("custom_button", $recordId);, where custom_button is the name of button. In your case instead of custom_button you'll have the name of the button. If you want you can rename it.
In the After record processed event add something like this
IF ($data['Clock_in']) $pageObject->hideItem("custom_button", $recordId);
The button for "Clock in" is named custom_button and the field is named Clock_in.
After clicking the button Assuming that you write the time to Clock_in field then in Client after event of button add this code

pageObj.toggleItem("custom_button", false, row.recordId() ); to hide the button

Do tha same for "Clock out" button.
