Post Title (concatenate files)

I created a quick form here:
http://gravity.chrishajer.com/title-test/

I added two fields, First half of the title and Second half of the title. These are NOT Post type fields, just normal single line text inputs.

Then I added a Post Title field, and marked it admin only. That will prevent it from showing up on the front end where people would be required to enter a value. Be sure that you DO NOT mark this as required, as the form validation will fail (the user can't see it because it's admin only, but you marked it required, which they cannot abide by.)

For that field, check "Create content template". That will enable you to concatenate two single lines of text into one line, the title. After you click that check box, you will be presented with a drop down that says "insert form field" by default, and in the drop down are the other fields on the form, plus some other information which is captured by Gravity Forms.

Here's what my Content template for the Title looks like:

{First half of the title:1} || {Second half of the title:2}

That takes my first field, adds the " || " in the middle, then adds the second field and uses that as the post title. You can see an example submission here:

You might want to limit the number of characters in your two single line text inputs as the two lines when added together might get very long.

If you need more help, please let me know. Feel free to submit the form if you want to see how it works.

Please post back when you have it resolved or if you need additional help.
