I have created an editable PDF via Adobe Indesign. When I open the PDF in Adobe Acrobat Pro DC, is there a way to specify a font style? Or is there a way in InDesign to make sure when someone type in that text field it is a certain font?

Question

I need to make sure the text that is entered is a certain font to keep it continuous with the rest of the document. Thank you!

Answer 1

To go into form editing mode, select "Prepare Form" in the right hand pane. You'll then get a toolbar along the top that contains the various form-related tools. The first thing to do is add a temporary button. You'll use this to determine the name of the font for use with the script as well as place the script that will change the font properties of the text fields. So create a button anywhere, double-click it to bring up the field properties dialog, and on the Actions tab add a JavaScript action to the Mouse Up event that is:
// Mouse Up script for temporary button
app.alert(event.target.textFont);
On the Appearance tab, select the font that you want to use for the text fields. Once you've done that, close form editing mode and click the button. It will display a popup that will list the font name. This may be different than the name that appeared in the dropdown on the appearance tab, so write it down. For example, when I chose "Minion Pro" from the dropdown, the popup showed "MinionPro-Regular".
The next step is to replace that Mouse Up script with the following:
// Mouse Up script for temporary button
// Change the font and font size for all text field in this document
for (var i = 0; i < numFields; i++) {
    var f = getField(getNthFieldName(i));
    if (f.type === "text") {
        f.textFont = "MinionPro-Regular";
        f.textSize = 9;
Replace "MinionPro-Regular" with the font name that you wrote down before and set the font size to whatever you want. Use 0 to specify a font size of "Auto".
This script will change the font of all text fields to whatever you specify. When you've confirmed that the text fields are set up as you want, you can go ahead and delete or hide the button. If you think you'll be doing a lot of forms work, you can create custom tools in Acrobat to speed up this process, but this should get you started. InDesign won't let you specify a lot of field properties and actions, so you have to work this way, and using automation scripts is an accessible way to significantly speed up the process and avoid mistakes.
