Hi PHPR Community,
I'm not sure what's happening but using just the code found on the ajax.addPDF online manual doesn't seem to work. No error and I used JavaScript alert() to get any return value from a variable nothing seem to show unless if I remove the ajax.addPDF() block then I get the return value.
Thank you.

The code from the manual does work. It is hard to understand what you doing though as you cannot "return value from a variable", this is a function, not a variable. Also it is not supposed to return any values:

Hi Sergey,
Ok this is what I did.

  • I created a custom button on the View page named: formhf_edit_button
  • CLIENT BEFORE code:



//just for debugging purpose...

alert('trigger client before');

params["from_client_before"] = "from client before";
//declare ajax.addPDF

ajax.addPDF("pdf", {});

return false;


  • SERVER code:



//for debugging purpose...

$result["from_server"] = $params["from_client_before"] . "->" . "from server ->" . "to client after";
//initiate PHP function

file_put_contents("file.pdf", $params["pdf"]);


  • CLIENT AFTER code:



//for debugging purpose...

alert('trigger client after');

alert(result["from_server"]);



  • The alert() on CLIENT BEFORE will show. But not the alert() on CLIENT AFTER.
  • But if I comment the code on the CLIENT BEFORE:



//ajax.addPDF("pdf", {});

//return false;



Then, it will trigger the CLIENT AFTER alert().
On what I understand, its like the ajax.addPDF() on the CLIENT BEFORE doesn't get initiated.
If I comment it, the tri-part event will run normally and even save a file.pdf (which is invalid because ajax.addPDF() is commented).

I think you need to use/define a callback in the ClientBefore event to trigger an after event, it's mentioned in the documentation you referenced.
