How to "lock" the form after filling it with the reader version?

[marketingn83032830]

I have been making some PDF for my clients for them to edit information and after that, they send it to third part but, of course, need to "lock" the PDF after using a reader version. Is it possible?

[try67]

Sure. Try this:

for (var i=0; i<this.numFields; i++) {
	var fname = this.getNthFieldName(i);
	if (fname=="FieldNameXYZ") continue;
    var f = this.getField(fname);
    if (f==null) continue;
    f.readonly = true;
}

Thanks a million for your fast reply 🙂

I'll test it and let you know the result.

In the meantime I got a different script from a friend and it works perfectly.

Tried to share it, but I get this error message from Adobe... so I can't...

Thank you again and kindest regards.

Stay safe,

Nuno

Hi This is brilliant - How would you add a number of fields to leave open?

[Bernd Alheit]

Add the same line for other fields.

[Kl5C28]

ok can I only disable a handful of fields instead, please help me with the syntax I am still very new at JS

[try67]

You can do it like this:

var fieldsToSkip = ["FieldNameXYZ", "FieldNameABC", "FieldNameEFG"];
for (var i=0; i<this.numFields; i++) {
	var fname = this.getNthFieldName(i);
	if (fieldsToSkip.indexOf(fname)!=-1) continue;
    var f = this.getField(fname);
    if (f==null) continue;
    f.readonly = true;
}

Edit the first line of code to include all the names of the fields that you don't want to "lock".

Thank you for this code! Super helpful. I was wondering though, is there a way to toggle between locking the form and unlocking the form? 

[try67]

Sure. Just change this line:

f.readonly = true;

To:

f.readonly = false;

[Newbie Lana]

Ohh!! This worked. For any newbie wondering, I created a "lock data" button and an "unlock data" button and with the unlocked version I put the above code, minus the below code... (and with false, of course). Thanks, try67!

var fieldsToSkip = ["FieldNameXYZ", "FieldNameABC", "FieldNameEFG"];

Thanks try67 for this 

would clearfy this steps to get use will of your knowledge,

also need how about if we need to exclode more than one field from locking the form? can we get your support with this try67 

thanks

[try67]

You can specify as many field names as you wish in the fieldsToSkip array...

How do I remove the readonly to get back into my document?

[try67]

Change "true" to "false" (without the quotes) in the last line of code above.

Thank you.

Although this is marked as Not Answered, the instructions work like a charm!  Exactly what I needed.

I know this is post is older yet it helped me do exactly what i needed at first.  Is it possible to reverse the read only after the scritp is run?  I've been unable to figure that out.

Run a similat script that sets readonly to false. Bear in mind there is no such thing as a form that can't be changed, if you are hoping for some kind of security.

"Is it possible to reverse the read only after the scritp is run?"

Yes.

Replace this line:

f.readonly = true;

By:

f.readonly = false;
