[SOLVED] can't seem to pass 1 variable via sessions

koolaid · May 26, 2008

Yes i am extremely new at this. Sorry i can not seem to wrap my head around sessions. It is supposed to be very straight forward i need to pass 1 variable from page to page via sessions. What am i doing wrong?

start my session

<?php
session_start();
   $_SESSION['username'] = $_POST['thename'];
  session_write_close();
?>

the next page

<?php

   session_start();
   
  echo $_SESSION['username'];
   

?>
<br>username = <?php print $_SESSION['username'];?>..

Please and thank you!!!!!

is there a form that submits $_POST['thename']?

koolaid · May 26, 2008

yup, and it works fine on a mac in firefox, but not anywher else

BlueSkyIS · May 26, 2008

hm. i'd like to see more of the code. firefox will let you get away with stuff that might not work on other browsers. is your HTML FORM tag closed? is there anything before your PHP session_start()?

koolaid · May 26, 2008

My form is in flash. I know flash is sending the var to the php file. I am collecting user data and writting it to my server via php. This is the entire php script that flash calls

<?php
session_start();
   $_SESSION['username'] = $_POST['thename'];
  session_write_close();

///my flash variables
///$_POST["repsName"] . $_POST["clientsName"]. $_POST["clientsPhone"]. $_POST["clientsUrl"]. $_POST["shortDescroption"]. $_POST["longDescription"];
$folder = "./files/".$_POST["thename"]."/";
if(!is_dir($folder)) mkdir($folder, 0755);

$mode = file_exists($folder.'user_input.txt')?'a':'w'; // append if file exists otherwise create it
$fp = fopen($folder.'user_input.txt',$mode);  // open file
foreach($_POST as $K=>$V)
{
  if($K != '_searchKey')
  {
  fwrite($fp, "$K=$V\r\n");  // dump the contents of the $_POST array to the file

  }

}
fclose($fp);


?>

Then flash executes this function when the data is sent (if you are not familiar with Action Script I can assure you that this part is functioning)

[AS]

myLv.onData = function():Void

{

status_txt.text = "save successful...";

getURL("http://www.molaeemedia.com/matt/testsDelete/session/varpassing.php","_self");

};

[/AS]

Then when redirected via the flash it pulls up this page

<?php

   session_start();
   
  echo $_SESSION['username'];
   

?>
<br>username = <?php print $_SESSION['username'];?>..

I really have been trying to do this on my own for three days now. I am at wits end if there ever was wits : )

Really, i only need to pass the one variable. It should be easy.

koolaid · May 26, 2008

I forgot to add that it writes all the information i want it to write to my server. just not passing the var via session data. Do i need to assign a session id or something? Everything i read tells me that what i am doing should work.

BlueSkyIS · May 26, 2008

oh, so you're essentially using flash as a browser to submit form data? that makes me wonder whether Flash can/will handle the session cookie properly. maybe not, which could be the problem. as you mentioned, you might need to retrieve the session_id and add it to the GetURL.

koolaid · May 26, 2008

2 things:

1. if it was flash not retrieving the data it should still display in the <br>username = <?php print $_SESSION['username'];?>.. before the flash piece right?

2. how would i assign a session id and retrieve it?

koolaid · May 26, 2008

OMG i got it!!!! I Knew it wasn't my flash because it was writting all the info i wanted to my server so that meant flash was sending the info. I was not assigning a value with my php to "username" prior to my form submitting data. So i was declring a variable then leaving it blank. So i just made it bob (working code below). For some reason that made all the difference. 2 days of pulling out my hair and naming my var bob was all I had to do. Well atleast no i can pass variables in between flash pieces via session data. Thanks a lot Bluesky for trying to help this dummy.

//page 1:

<?php

   session_start();
    $_SESSION['username'] = 'bob';
  echo $_SESSION['username'];
  session_write_close();
   
?>
