php sessions with checkboxes

[ashutoash]

Hi,

 

I am trying to use PHP session variables with checkboxes. My page has 3 checkboxes and those display and hide data according to check and uncheck. This page automatically refreshes every 5 mins. I want to save the checkboxes session and let them be the same on refresh or reload.

I am passing the values of the checkboxes that is (on or off) via ajax to another page so that I can get them back on the main page. No matter whatever I do, the boxes are always on. Help lease.

 

Main page code:

session_start();
      /* Includes */
      date_default_timezone_set("UTC");
      include("include/SPDB.php");
      //include("include/database.php");
      
      if(!isset($_SESSION["PL"]))
      {
         $_SESSION["PL"] = $_GET["pl"];
      }
      if(!isset($_SESSION["JIT"]))
      {
         $_SESSION["JIT"] = $_GET["jit"];
      }
      if(!isset($_SESSION["LAT"]))
      {
         $_SESSION["LAT"] = $_GET["lat"];
                 }

Div tag on this page:

<div id="metricoptions">
            <? 
         if($_SESSION["PL"] == "on")
            echo "<input id=\"ploss\" type=\"checkbox\" name=\"metricoptions\" checked=\"checked\" />Packet Loss";
         else
            echo "<input id=\"ploss\" type=\"checkbox\" name=\"metricoptions\" checked=\"checked\"/>Packet Loss";
         if($_SESSION["JIT"] == "on")
            echo "<input id=\"jitter\" type=\"checkbox\" name=\"metricoptions\" checked=\"checked\" />Jitter";
         else
            echo "<input id=\"jitter\" type=\"checkbox\" name=\"metricoptions\"/>Jitter";
         if($_SESSION["LAT"] == "on")
            echo "<input id=\"latency\" type=\"checkbox\" name=\"metricoptions\" checked=\"checked\"/>Latency";
         else
            echo "<input id=\"latency\" type=\"checkbox\" name=\"metricoptions\"/>Latency";
         ?>
        </div>

Ajax call on this page:

$.ajax({
          type: "GET",
          url: 'sessionVars.php?pl=' + $('#ploss').val() + '&jit=' +  $('#jitter').val() + '&lat=' +  $('#latency').val(),
       });

sessionVars page:
session_start();
   
   $_SESSION["PL"] = $_GET["pl"];
   $_SESSION["JIT"] =  $_GET["jit"];
   $_SESSION["LAT"] =  $_GET["lat"];

Also I use live click function for the checkboxes. Thanks.

firstly, you have not assigned unique values to your check boxes, so I'm curious as to how you are checking to see which ones are checked before refresh..?Also, have you checked to see what is getting passed to your sessionvars.php page

@Fugix:

 

When I alert the checkboxes, the value "on" is displayed and this is getting passed to the sessionVars page and the same thing is coming back to the main page.

[fugix]

if($_SESSION["PL"] == "on")
            echo "<input id=\"ploss\" type=\"checkbox\" name=\"metricoptions\" checked=\"checked\" />Packet Loss";
         else
            echo "<input id=\"ploss\" type=\"checkbox\" name=\"metricoptions\" checked=\"checked\"/>Packet Loss";

here you are saying that regardless if the person has checked it or not, it will echo a checked box.

do you mean

if($_SESSION["PL"] == "on")
            echo "<input id=\"ploss\" type=\"checkbox\" name=\"metricoptions\" checked=\"checked\" />Packet Loss";
         else
            echo "<input id=\"ploss\" type=\"checkbox\" name=\"metricoptions\" />Packet Loss";

Yeah by default Packet Loss will be checked always and others vary according to check uncheck. Do you suggest that I give each of the checkboxes a unique value like 1,2,3 or something and check if those values are posted via Ajax?

[fugix]

in a nutshell, yes give each checkbox a unique value

I have given them unique values....but is there some thing wrong with my ajax part? Say if I am on a page now and have ploss checked, jitter checked and latency unchecked....the ajax call no matter what is only sending one value even if it's set otherwise and on refresh all the three are returned checked. Are there any ajax function like on refresh or on reload?

$.ajax({
		 type: "GET",
		 url: 'sessionVars.php?pl=' + $('#ploss').val() + '&jit=' +  $('#jitter').val() + '&lat=' +  $('#latency').val(),
	 });

[fugix]

honestly i don't understand what you are saying in the first part of your explanation, my apologies, second.. did you use the if else statement that i posted for the remainder of your check boxes? if you did, there is no way that the default is to have them checked.

Never mind ...I figured it out. Thanks for you help.
