For those who are renting to a community of members and so, wish to be able to pick-up email automatically, here is my contribution:
/wp-content/plugins/booking-system/includes/forms/class-frontend-forms.php
add:
if ($field->translation =='Email'){
global $current_user;
get_currentuserinfo();
$field->value=$current_user->user_email;
}
/wp-content/plugins/booking-system/assets/js/jquery.dop.frontend.BSPCalendar.js around line 5237
For text fields, modify as below:
HTML.push(' <input type="text" name="DOPBSPCalendar-form-field'+ID+'_'+formField['id']+'" id="DOPBSPCalendar-form-field'+ID+'_'+formField['id']+'" value="' + formField['value'] +'" />');
