Enqueuing scripts for custom content area

I'm using some custom meta boxes with TinyMCE fields to let the client edit separate tabs on a page. When they embed a Gravity Form in one of these fields, the necessary scripts don't get enqueued.

It looks like this is because GFFormDisplay::enqueue_scripts looks through the current WP query content for forms. I'm wondering, might it be possible for Gravity Forms to scan for forms using the the_content filter? I output all my custom TinyMCE fields with this filter, so presumably the forms would be detected, and the scripts would go in the footer.

Meantime, could you help me with a hack? I've tried this in my theme's functions.php:
```
add_filter( 'the_content', 'slt_enqueue_gforms_scripts' );
function slt_enqueue_gforms_scripts( $content ) {
	$forms = GFFormDisplay::get_embedded_forms( $content, $ajax );
	foreach( $forms as $form)
		GFFormDisplay::enqueue_form_scripts( $form, $ajax );
	return $content;
}
```
However, it seems that enqueue_scripts can't call get_embedded_forms, because the latter is a private method. Any way to do this?

Hi Steve,

The problem is "the_content" fires way too late for enqueueing scripts/styles. Enqueueing styles needs to happen before the header is rendered.

What you can do is print the scripts using the GFFormDisplay::print_form_scripts($form, $ajax); function. For more details, take a look form_display.php circa line 700.

Why can't you have a filter on the_content which would then enqueue with the $in_footer parameter set to true? Then, if some content with a Gform shortcode is placed somewhere after the header has rendered, the scripts would go in the footer.

Regarding GFFormDisplay::print_form_scripts (line 1175?), do you mean to print the scripts inside the <body> when the_content filter is run? Or to set a flag in the_content, and then print scripts in the footer if the flag is set?

Hi Steve,

After a certain point, I do not believe it is possible to enqueue a script, even with the $in_footer flag set to true. Feel free to correct me on this if you have a method that works.

In regards to the print_form_scripts() function, you can do this a couple ways.

1) Print the scripts inline with the Gravity Form wherever the shortcode is found.
2) Similarly to your own idea, set a flag if the scripts need to be loaded, then add a hook in the footer to user the print_form_scripts() function that checks the flag and if true, prints the scripts in the footer.
