TENGO UN MENU TIPO ARBOL CON UNA TABLA RECURSIVA QUE ME JALA LOS DATOS AL ARBOL
LA GRAFICA BIEN PERO NECESITO QUE AL SELECCIONAR UNO DE LOS CAMPOS DEL MENU
EJEMPLO:
- AZUAY
- CANTON
- PARROQUIA (SELECCIONO CON EL MOUSE)
ME CAPTURE ESA SELECCION EN UN CUADRO DE TEXTO DE ESTE MODO : AZUAY/CANTON/PARROQUIA
Código PHP:
class tree{
var $elementArray = array();
var $nameOfCookie = "menu_expandido";
function tree()
