Auto-populate field value

You can pre-populate a field value, e.g. through a parameter in the URL, by using the pewc_default_field_value filter.

<?php
/**
* Filter the default field value using a value from a parameter in the URL
*/
function prefix_default_field_value( $value, $id, $item, $posted ) {
if( isset( $_GET['my_param'] ) ) {
$value = $_GET['my_param'];
}
return $value;
}
add_filter( 'pewc_default_field_value', 'prefix_default_field_value', 10, 4 );

You can see how to add a snippet here.
