Sort array

[pjf5066]

Happy Tuesday !

I am trying to sort an array based on a field.  The field is a checkbox called user_terminated.  I would like to sort this array on the date that the checkbox 'user_terminated' was checked.  This will provide me a list of all terminated users from my system in order of the latest term on top.  Thanks for any help!

ProcessWire doesn't store metadata of changes, it only stores the new values and that's it. If you want to get this functionality, you would need to build a small module which hooks into page::save and saves the date to a hidden date field, if the checkbox got checked. This way you can store and sort by date and status.

PW doesn't store the date/time a field is changed. I think the easiest approach might be to add a hidden field called date_terminated. Then add a hook on page save that sets the date if the checkbox field has been checked.

Place this is your admin.php file.

wire()->addHookAfter('Pages::saveReady', function(HookEvent $event) {
    $page = $event->arguments("page");

    if($page->user_terminated == 1 && $page->date_terminated == '') {
        $page->date_terminated = time();
    }
});

That is a little rough but will hopefully get you started. You should add an if statement to limit this to just the relevant template so it is not run on all pages. I am sure other improvements could also be made.

Thank you

Maybe a check to see if the checkbox has changed?

$changed = $page->isChanged("mycheckbox");

Or there's a ___saved() hook 

___saved(Page $page, array $changes = array(), $values = array())

Untested example

wire()->addHookAfter('Pages::saved', function(HookEvent $event) {
    $page = $event->arguments("page");
    
    if($page->template != "mytemplate") return;

    $changes = $event->arguments("changes"); // array of changed fields
    if(in_array("myfield", $changes){
       // do stuff
    }
    
});

Hello,

today I need this and try adrian and Soma solutions but with partial success (PW 3.0.42).

Finally solved with this:
 

wire()->addHookBefore('Pages::saveReady', function(HookEvent $event) {    
    $page = $event->arguments('page');    
    if($page->template != "your_specific_template_name") return;
    if($page->isChanged('your_target_field_name')){       
      // your code       
       $this->message('Your message about changes...');  
    }    
});

Main difference is "changes" argument, or  $page->isChanged('some_field_name')

Regards.
