Can Acrobat auto populate a Name field upon digital signature of a form?

I know you can auto populate a Date Field upon Digital Signature from a form but I'd also like to auto populate a Name Field. I am making a form which requires a Digital Signature for approval, along with the client's Name and Date of Approval. I have added the required Java script to generate the Date but I was wondering is there a way to generate the Name based on the name information from the digital signature?

Extracting from ls_rbls - this is what worked perfectly for me.
When signed, the document fills out a date stamp next to it automatically.

Insert Text Box next to Signature > Right-click the Text Box > Properties > mark Read Only and close.

Script: Right-click the Signature > Properties > Signed > Edit > Paste the following:

var f = event.target;

var sigInfo = f.signatureInfo();

this.getField("Text34").value = util.printd("yyyymmdd", new Date((util.scand("ddd mmm dd yyyy HH:MM:ss ZZ", sigInfo.date ))));

if (f.signatureValidate()==4);

... but ... Hahah.

If I remove the signature, how do I delete the data without changing the box to NOT be Read-Only.

Great!

And thank you for sharing this.

To clear the contents of the date field when the signature field is cleared, you may use a custom validation script or custom calculation script executed directly from the date field.

Something like this:

if(this.getField("mySignatureField").value == "") event.value = "";

OR,

You may also add a Mouse Exit event to the signature field:

if(event.target.value =="") this.getField("Text34").value = "";

}

With the latter script, when the signature field is cleared and the mouse pointer is moved outside of that field it will set the date field to a blank value.

You can use this code to do it (as the Signed script of your signature field):

var f = event.target;
if (f.signatureValidate()==4) {
	var Info = f.signatureInfo();
	this.getField("SigName").value = "Signed by: " + Info.name;
	this.getField("SigDate").value = "Signed on: " + Info.date;
} else {
	this.getField("SigName").value = "";
	this.getField("SigDate").value = "";
}

Thank you so much!!

I've spent literally 8 to 12 months trying to figure this out.

Hi,

I've been trying to work on similar with a PDF form of my own.

I've recently came accross this possible solution but I haven't tested it on my end:

This is an old thread for the date , there is a very short script that works for me for the date part:

https://community.adobe.com/t5/acrobat/can-acrobat-auto-populate-a-date-field-upon-digital-signature-of-a-form/td-p/4524073

Si when you say digital signature I assume you're referring to electronic signature in the context of digital certificates by which certificate validation and encryption are involved.

You may also need to dig deeper on how to use signatureInfo part in your script to get first, middle, last names appropriately from such digital certificate signatures.

Just to clarify, I already have this script in the: Digital Signature Properties > Signed > This script executes when field is signed >

// JavaScript code to add the date at signing time var currentTime = new Date() var month = currentTime.getMonth() + 1 var day = currentTime.getDate() var year = currentTime.getFullYear() var signingTime = day +"/"+month+"/"+year //Modify into your preferred format var f = this.getField("Date1_af_date"); //Modify the field name as necessary f.value = signingTime;

Which propagates the correct date in the Date Approved filed of my form when the Signature is actioned. There's also a Approved By field where the user enters their Name. I was hoping the name supplied in the digital signature could be used here but I have no idea what script to use. And, even if there was a script would it clash with what's already there for the date action?

in the first link that I posted earlier above you can use that one to grab the name.

Here is how I would do it:

To avoid the two scripts clashing you don't need to use the same ApprovedBy field; use two fields instead but make it seemless to the user by marking them as readonly.

In your signature filed you can add two separate javascript actions that will execute when the signature is applied (one for the date, but you have to indicate to which field it will write to using getField method).
Do the same for the script that will grab the name and write to the second field where you want that name to be output using this script as reference: https://experienceleaguecommunities.adobe.com/t5/Adobe-LiveCycle-Questions/Create-digital-initials-after-signing-a-form-using-a-signature/qaq-p/158630

So again, a quick easy solution is to create two read-only text form fields (one that will grab the date from the signature field and the other one to grab the name ).

All you have to do is add a custom calculation script in both of those text form fields like:

for the date try this:

var grabdate = this.getField("yoursignaturefieldname").valueAsString;

if (grabdate=="") event.value ="";

or use this other method if you choose to use a datefield where the date will be pulled from the signature field with this other method: https://stackoverflow.com/questions/35232909/how-do-i-trigger-javascript-events-when-a-signature-is-cleared-in-acrobat-11

And for the field that will pull the name portion of the signature field use the same script above that I just typed as a reference in the custom calculation script section of that text field:

(getField("mySig").value !== '') // signature is present    getField("myDate").value = global.getCurDate(); // custom function for a mm/dd/yyyy date
else    getField("myDate").value = '';

but change the global ogject from global.getCurDate to the appropriate

global.get object of the API reference
