you need first set session , session value.after value put if else condition.

step 1 first set session follow:(put code in function.php)

add_action('init', 'mystartsession', 1); function mystartsession() {     if(!session_id()) {         session_start();     } } 

step 2 session value (if user set second value if part execute )

note session set

if(isset($_request['menu_select'])){ $get_val = $_request['menu_select']; if($get_val =='meniu_1'){$_session['menu']='meniu_1';} elseif($get_val =='meniu_2'){$_session['menu']='meniu_2';} elseif($get_val =='meniu_3'){$_session['menu']='meniu_3';} else{$_session['menu']='default';} } if($_session['menu']=="meniu_1"){ //you compare value in condition //menu 1 code }elseif($_session['menu']=="meniu_2"){ //menu 2 code }elseif($_session['menu']=="meniu_3") { //menu 3 code }else{  //menu default code }
