Gravity Forms and dynamic content

Replies: 0

Hello,
I want to create popups with a Gravity form inside using this guide:
http://docs.wppopupmaker.com/article/53-create-read-more-popups-for-posts

Firstly, I tried to make something like this (call shortcode in shortcode), but that was bad idea (popup was clear).
echo do_shortcode("[popup id='product-". get_the_ID() ."']". [gravityform id="1" title="false" description="false"] . "[/popup]");

After that, I found a second way to call a form, but looks like this function use echo too, so my form going out of popup:
gravity_form(1, false, false, false, '', true);

So, tried to add it to buffer and replace the form function in popup called with a $output:

	ob_start();
	gravity_form(1, false, false, false, '', true);
	$output = ob_get_contents();
	ob_end_clean();

And I got errors in console:

(index):565 Uncaught SyntaxError: Invalid or unexpected token
(index):573 Uncaught SyntaxError: Unexpected token <
(index):679 Uncaught SyntaxError: Invalid or unexpected token
(index):687 Uncaught SyntaxError: Unexpected token <

When I looked at this lines – the code (javascript) from the form got tags <p> (something like this):

			<p>        <script type="text/javascript"></script></p>
<p>        (function($){</p>
<p>            window.gwdc = function( options ) {</p>
<p>                this.options = options;
                this.startDateInput = $( '#input_' + this.options.formId + '_' + this.options.startFieldId );
                this.endDateInput = $( '#input_' + this.options.formId + '_' + this.options.endFieldId );
                this.countInput = $( '#input_' + this.options.formId + '_' + this.options.countFieldId );</p>

Disabling autop (from content and excerpt doesn’t help, also when I’m echo buffer out of popup – there is no autop)

After that – I tried to create a function that will return my content (tried with buffer and without it) – all the same like without that function:

function lol() {
	ob_start();
	gravity_form(1, false, false, false, '', true);
	$output = ob_get_contents();
	ob_end_clean();
	return $output;
}

So, how can I call the form in popup maker for all posts?
