I know that similar questions have been posted before, but I need to be sure if this exactly the same thing I need to achieve.
I need a custom field to be populated with information from another custom field (specifically image field), all this within the same form.
Example.
Field 1: Post Image.
Field 2: Custom Field.
When the user uploads the image in the first field, the second field will be populated with the direct image url. Can this be done?.
You can do this with the 1.5 development release by using the content template functionality of the Post Custom Field which allows you to create a content template and use field values to generate the value of the field that is stored in WordPress.
The development release of Gravity Forms v1.5 is available to all users. It's available on the Downloads page. The content template functionality is an option on the Post Custom Field if you are running the 1.5 development release.

I installed the 1.5 version, and configured the Post Custom Field to be filled in with the Post Image url.
I suppose that the post custom field should be a hidden field since it will be generated by gravity itself rather than the user, is this correct?. If so, how do i do that.
To hide this Post Custom Field do the following...
- Edit the field
- Select the Advanced tab
- Under Visibility select "Admin Only"
- Save your form
In the content template for the custom field you would use the "Insert form field" drop down that appears just above it and select the image field, it will then show a second drop down to select the size. See this screenshot:
You pick the size of the image you want to insert into the custom field. Don't pick one of the sizes with the alignment options, those are for when you are inserting it into the post body because it includes the HTML markup to do those standard WordPress alignments. So just pick the size type.
Once you do that it will then insert a form field variable that will look something like this:
Now we need to do a minor manual adjustment to the variable. If you leave it as is it's going to put markup in the custom field and wrap the image in an HTML img tag, it isn't going to output just the SRC url to the image itself. To output the SRC url to just the image itself as the value of the custom field we would modify the variable. See this screenshot:
So by changing our post image variable from something like this:
{Post Image:3:thumbnail}
To this:
{Post Image:3:thumbnail:url}
It will not output the full URL path to the image rather than the HTML markup that displays the image.
Please keep in mind the variable names are form specific to my examples above may not work on your form.
