sessions

[spearchilduser]

hey i think i may have stored session variables incorrectly

 $_SESSION['tel'] = $_GET['Lat'];
		$_SESSION['Lon'] = $_GET['Lon'];
		$_SESSION['Lat'] = $_GET['Lat'];

is what i used to set the session variables with the data i then enter these into a table and they enter the correct information but two pages down the line i try to access them however i just get undefined variable when i set the variable is equal to the session.

$MyLon = $_SESSION['Lon'];
$MyLat = $_SESSION['Lat'];

 

the following is the errorr

Notice: Undefined index: Lat in

make sure each page has

session_start();

at the top

[spearchilduser]

Yer they all have

	<?php 
session_start();

at the top of every page

what is the code your using to retrieve the varibles?

[batwimp]

Post the line where the error is pointing.

[spearchilduser]

$MyLon = $_SESSION['Lon'];
$MyLat = $_SESSION['Lat'];

 

echo $MyLon;
echo $MyLat;

 

as this is not showing me the results i expect im not tryign to use the data just yet

Have you verified your GETS are passing in values before you assign them to the session variables?

 

var_dump($_GET);

[spearchilduser]

Yes im using the original gets to enter the information into the session variables then on the same page usign the session variables to enter the data into a table to check they were working

[spearchilduser]

aww sorry i dnt know what var_dump($_GET); is or how it woudl be used

[batwimp]

It will print to the screen what is currently in your $_GET array. It will let you know if they are being populated correctly from your form. Put it right before you assign to your session array:

var_dump($_GET);
$_SESSION['tel'] = $_GET['Lat'];
		$_SESSION['Lon'] = $_GET['Lon'];
		$_SESSION['Lat'] = $_GET['Lat'];

This will print some text out to the screen to let you know what is in your GET array. Copy that output and paste it here.

thats gunna be a little difficult becuase the information is gathered on the login page which then goes to another page whcih checks the login details and where it stores the details into sessions then redirects you to another page so at no point can i check but now ive added that line in it does like the page syas theres a problem

[batwimp]

Ok, so for debugging purposes, stop the script right after the dump so you can see if there's anything in there:

 

var_dump($_GET);

exit;

$_SESSION['tel'] = $_GET['Lat'];
		$_SESSION['Lon'] = $_GET['Lon'];
		$_SESSION['Lat'] = $_GET['Lat'];
