Function call and $field_values

Hello,

I'm trying to use the function call -way to import a form into a Wordpress theme page. This works great with:

gravity_form(
		3,
		$display_title=false,
		$display_description=true,
		$display_inactive=false,
		$ajax=true,
		$field_values = array(
			'namn'=>$namn,
			'url'=>$url,
			'vanlig_url'=>$vanlig_url,
			'typ'=>$typ,
			'registrering'=>$registrering,
			'kategori'=>$kategori)
		);

As you also can se I'm trying to add field values through the $field_values command. And here it's where I bump into problem.

Nothing want show up in the hidden fields which I added when creating the form. The hidden fields are set to the following:

"Allow field to be populated dynamically" is checked
"Parameter Name:" is set to the six seen above in the code
Label name is also set to the six seen above in the code

The parameters $namn, $url, $vanlig_url, $typ, $registrering, $kategori are all checked and the output the information I want in my hidden fields.

The source code which is being output looks like this:

<li id='field_3_3' class='gfield     gform_hidden' >
<input name='input_3' id='input_3_3' type='hidden' class='gform_hidden' value='' />

<li id='field_3_4' class='gfield     gform_hidden' >
<input name='input_4' id='input_3_4' type='hidden' class='gform_hidden' value='' />

<li id='field_3_5' class='gfield     gform_hidden' >
<input name='input_5' id='input_3_5' type='hidden' class='gform_hidden' value='' />

<li id='field_3_6' class='gfield     gform_hidden' >
<input name='input_6' id='input_3_6' type='hidden' class='gform_hidden' value='' />

<li id='field_3_7' class='gfield     gform_hidden' >
<input name='input_7' id='input_3_7' type='hidden' class='gform_hidden' value='' />

<li id='field_3_8' class='gfield     gform_hidden' >
<input name='input_8' id='input_3_8' type='hidden' class='gform_hidden' value='' />

What am I doing wrong? And how to solve it?

That worked fine.

I have a following question due.

The above code is suppose to be in a form where the visitors can write a review (post body of post) if there is none written (post body). I have a connection to a custom post type (through the available fix Gravity Forms + Custom Post Types).

Example:
Title: Toyota Supra
Post body: Not-written-yet
Field values: Type=Car, Color=Red, Speed=Fast

As you can se above example should be able to be updated through a form. I do a check with a if-expression to se if the post body is empty (this works fine showing the form). In above example this is the case.

So I show a form (Gravity form) and the visitor could write a review into the post body. I take all the other values and send with through hidden fields.

But when I sign this form up it will not update the old one, instead showing up like a copy beside the other.

How can I do to update the existing post with just the post body that the visitor have written?

Hi there,
I do not understand the $field_values in the the above example. I could not find anything in the documentation yet either. Can the $field_values also be used when calling a form by shortcode? Would I use $field_values to pre-populate fields?

How would I set a form up, so that it does not create a post, but uses the wp_update_post function instead?
