Required Fields

[Post_Foxit]

On an interactive form, is there a way to require that certain fields be filled in? We have inspection forms that must be filled out properly and the desire is to not allow saving or printing the form unless certain fields have been filled in/checked/whatever.

Post_Foxit Your requirement can be accomplished by Javascript. Can you please give me your email address and I can send demo file with JS to you for reference? Also, you can send email to us via [email protected]
Thanks.

Yes you can use [email protected], and thank you.

A user may have many good reasons for wanting to save or print a form before having finished filling it out (announced power cut, appointment, interruption, emergency, etc.).
Luckily for him you can't prevent him from saving or printing.

It is much more user-friendly to just display an alert when the user is saving or printing.

Actually, it is easy to do it. Please follow the directions below:
1. Open the document in Foxit PDF Editor.
2. Click on the Form Fields panel on the left nav.
3. Right click on the form to be required.
4. Under General Tab, check the > Required < checkbox.

Here is what I do:

• Create a Document JavaScript Function called Required with the following code.

function Required() {
  var c = 0;
  for (var i = 0; i < this.numFields; i++) {
    var fieldName = this.getNthFieldName(i);
    var f = this.getField(fieldName);
    if (f.type != "button") {
      if (f.required == true && (f.value == "" || f.text == "")) {
        c++;
      }
    }
  }
  if (c > 0) {
    app.alert("At least one required field is empty...",1);
    c = 0;
  }
  return;
}

• Then simply called the function with

  Required();

  in a field Action from the field properties: Actions > Select a Trigger > Select Action "Run a JavaScript"

I will note a few things: 1) this only checks if the Required fields are not blank and if one is then a simple warning alert is issued; there is nothing stopping the user from continuing to sign the PDF, for example... and 2) this works for Foxit PDF Editor for Mac and Foxit PDF Editor Pro for Windows (Parallels VM) but I cannot get these to work on Adobe Reader on either OS.

EDIT: do not use JS6 code, such as "let" or "const"; use "var." I have made this replacement in my code above.

Thanks for the details. The mentioned two discoveries have been submitted to Foxit internal bug tracking system for our JS engineer's further investigation and we'll keep you posted with the update. You may also use the Report ID#QCPHANTOM-29435 to track the processing status any time. Thank you.

Thanks, Cherry. I made an edit to my code. The JS6 code, like "let," does not compute for Adobe JS so you have to use the traditional "var." This topic was resolved in my post here: https://forums.foxitsoftware.com/for...editor-for-mac.
