Hello, please how can a GF price field be dynamically populated with a WP custom field?

The WP custom field IS in the post where the form is embedded.

Here you have a link to a post with a GF. The WP custom field is "Precio":

Alejandro, you can use the gform_pre_render filter to populate fields in your form. Here is the documentation for the filter: http://www.gravityhelp.com/documentation/page/Gform_pre_render

[php]
<?php
// change the 7 here to your actual form ID
add_filter('gform_pre_render_7', 'populate_price');
function populate_price($form) {
	// documentation: http://bit.ly/15C2BQu
	// get the price from the custom field for this post
	$price = get_post_meta(get_the_ID(), 'Precio', true);

	// set the value of your product price to the value which was retrieved
	if ($field['id'] == 1) {
		$field['price'] = $price;
	}

	// always return the modified form
	return $form;
}

That code will go in your theme's functions.php file and will need to be customized for the form ID (I used 7) and the field ID (I used 1). I used "Precio" for the meta key. That will need to match exactly as well.
