Change field colour depending on empty or completed field

Hi - I have an editable PDF form, that I basically want to turn all the fields red if the boxes are empty, once they have been completed they turn back to white - note they are just free text boxes not based on any specific values.

Its just as a prompt to the user to complete the field.

Can you advise please? I have got close using code I have found online but can't seem to get it to work correctly.

So I have toggled off the 'Show Border hover color for field' so it changed all fields to white.

However, I have added in the validation script to a couple of fields and no colour shows at all.

You have to change their values or clear the form for it to kick in.

Sorry.

"do you know how to make it apply to check boxes too?"

The principle is the same but as checkboxes don't have "Validate" nor "Calculation" it is necessary to execute the script from another field.

Place this script as a Validation script in each concerned field:

if (event.value == event.target.defaultValue) {event.target.strokeColor = color.red};
else {event.target.strokeColor = color.white};

- Add another line where you set the fillColor property, too. Like this:

if (event.value == event.target.defaultValue) {
	event.target.strokeColor = color.red;
	event.target.fillColor = color.ltGray;
}
else {
	event.target.strokeColor = color.white;
	event.target.fillColor = color.white;
}

- You probably enabled the fields highlighting, which will override these colors. To disable it go to Edit - Preferences - Forms and tick off "Show border hover color for fields". You can also do it from the purple bar at the top of the document when you open it.

So I have toggled off the 'Show Border hover color for field' so it changed all fields to white.

Hi Jadef

Hope you are doing well and sorry to for the trouble.

Please open the PDF form in Acrobat Pro DC > Go to Tools > Prepare Form > Double click on the Form field to open the form field properties and Select 'Required' to make the field required.

It will force the user to fill in the selected form field. If the user attempts to submit the form while a required field is blank, an error message appears and the empty required form field is highlighted.

This does not achieve what they asked for. A required field will always be painted in red, regardless of whether it has a value.

Hi Try67

Yes this is correct, I want all the fields red if the boxes are empty, once they have been completed they turn back to white. Do yoy know if this is possible?
