While using a front end form, could get values from a query?

Something like this: http://example.com/form?foo_name=bar, so when you click on the link that will take you to the form, the field called foo_name will be fille by default with the value bar.

Hi @gabyferman,

Hmm… I believe that this should be possible using the acf/load_value filter. The code should be as shown below:

add_filter('acf/load_value/key=<field_key>', 'my_text_value', 10, 3);

function my_text_value($value, $post_id, $field) {

	$value = isset($_GET['foo_name'])?$_GET['foo_name']:'default_value';

	return $value;
}

Have a look at the documentation for more information on this filter: http://www.advancedcustomfields.com/resources/acfload_value/

Hi,

I tried this approach, and while it work with the form it messes up all the other entries, they all get default_value as the foo_name field value

duh, I though default_value was a type of variable for ACF :$ I just change it for $value and it worked.

function my_text_value_group_type( $value, $post_id, $field ) {
	$value = isset( $_GET['foo_name'] ) ? $_GET['foo_name'] : $value;
	return $value;
}
add_filter('acf/load_value/key=<field_key>', 'my_text_value_group_type', 10, 3);

Thank you
