Thank's you for your fantastic support, I have two questions and the site is finished
1. I added a new fields in the search form, but does not work. In the file
{yours site} / components / com_realestatemanager / admin.realestatemanager.php
I found the function showSearchHouses and searchHouses. Which of the two functions I should changed for make a select in the db and retrieved the houses in the criteria?
2. I should add the house's videos. It's necessary add the new logic for video or If I change if I change the supported extensions and also add avi, say in the pictures should be fine?
Thanks for your patience but it is many years since I program with php
