Hi Armin, after that I have query a layer I can find in the "session file"
this string
JSON_Results|s:580:"[ [{"name": "Limiti_Provinciali", "description":
"Limiti_Provinciali", "header": ["@","PR"], "values": [ [{"shplink":
["Limiti_Provinciali","1","445635.40666512+4539798.8219411+512497.68423614+4592772.6295367"]},
"BN"]]} , {"name": "Limiti_Comunali", "description": "Limiti_Comunali",
"header": ["@","COMUNE"], "values": [ [{"shplink":
["Limiti_Comunali","47","475595.63608862+4548872.2345804+489090.57531073+4563727.3195491"]},
{"hyperlink": ["Limiti_Comunali","COMUNE","Benevento","Benevento"]}]]} ],
{"allextent": "", "zoomall": false, "autozoom": false, "infoWin": "window"} ]";
I need to retrieve the field value from this string in order to use it in a php
code like this (for example):
<?php
session_start();
$field_value = $_SESSION['only the field value in JSON_Results string'];
echo "The field value is " . $field_value;
?>
thanks
Marco
