Dynamically populate field within template file

I want to populate a form field with current post custom field that contains email address. I want to do it via template when embedding a form. Form is always the same, just this field needs to be populated in order to send enquiry directly to that email.

I'm using this chunk of code:

$owneremail = '\'owneremail\'=>\''.$o_email.'\'';
echo gravity_form(1, false, false, array($owneremail), '', false);

echoing $owneremail gives 'owneremail'=>'example@example.com' which should be fine according to your docs.
Form has a field that has checkbox ticked to populate dynamically with value owneremail.

And it doesn't get filled out.
You can see the form here: http://holidaysincroatia.hr/summer/accommodation/apartmani-nije-mi-dobro/#cnt-form
WP 3.5.1
GF 1.6.11

Funny, actually pretty strange that it does work with do_shortcode :confused:

You made a small mistake with variable, it should be like this, then it works:
echo do_shortcode('[gravityform id=\'1\' title=\'false\' description=\'false\' field_values=\'owneremail='.$o_email.'\']');

Thanks for helping out.
