Limit characters in a PDF form?

Wow, that was hard to find.  You know how some things are just hard to Google because the search terms are so common, and others are hard to find because everything on the entire Internet  starts with the presumption of some knowledge you don't have?  Well, this fell into both categories; even though I had a copy of Acrobat Pro and its help open as well!  You can also tell that Forms in Acrobat is something I've never done before.

Here's the deal (and you probably won't like it): custom validation is not available with LiveCycle forms, only with AcroForms.

Did you know there were two completely different incompatible types of form in there?  I didn't.

You don't "create" an AcroForm.  You create a vanilla PDF document, and you add form fields to it.  The easiest way is to enable the Forms toolbar (View | Toolbars | Forms); then you click on an icon to select, say, the text input tool, and then double click with that tool in the document where you want that field.  Right-click the field and select properties; when they appear, select the Validate tab, and you will see a box (enabled by a radio button) where you can put the custom validation script (cut and paste from the page I first linked you to).

Good luck!

If all else fails, you could put "Use letters (a b c) and numbers (1 2 3) only", which might be more clear than "alphanumeric".

Thank you so much for looking into that! Glad to know it wasn't just me having trouble finding answers - you're right about them assuming you have some prior knowledge of what to do. I guess I just need to look into putting a newer version of Acrobat on my computer. In the meantime, I may just have to suck it up and change the ones that are done wrong.


I don't have a lot of room to put the instructions for that field, and to be honest, people don't seem to be reading ANY of the instructions on the form. I thought "A-Z 0-9 only" would clear it up because maybe "alphanumeric" was just something they weren't familiar with, but apparently that didn't help either. grrr

celticgeek:
There is a general rule for that:  "If all else fails, read the instructions."  Applies to almost everybody.

@ celticgeek tl;dr: RTFM
