Having some probs with sessions

Snx

Hi I really hope someone can help, I am desparately trying to understand sessions variables and it seems very easy and logical except i have been stuck on this for a day now...

Problem is i am trying to stockpile unique data keys in the sessions array, very simply i might add... whats happening is instead of appending the new data to the end of the existing array, it seems it replaces the existing array completely and the old data is lost...

consider this example:

<?php
session_start();
header("Cache-control: private"); //IE 6 Fix

$word=$_POST['word'];
array_push($_SESSION, $word);
print_r ($_SESSION);
?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>I'm Gonna Lose It</title>
</head>

<body>
<br />
<br />
<br />
<FORM METHOD="POST" ACTION="thisone.php">
Word: <input type="text" name="word">
<input type="SUBMIT" value="Submit">
</FORM>
</body>
</html>

It doesnt make any sense to me that it is replacing the array instead of adding to it... i have tried a bunch of ways that seem totally going overboard such as copying the array adding to it etc... same result... am i missing something very obvious?

phpbuilder has been an invaluable resource although its the first time i have posted just want to say thanks & take care

ive had a simular problem. try replacing session_start() with...

if (!isset(session_id()) {
  session_start();
}

what is the name of the array you're trying to push to?
Right now you're pushing straight to the $_SESSION but not a specific array held in session.

hey thanks for taking the time to reply...

it seems i am trying to access $_SESSION as if its a numeric array when it needs to be an associative... hence the code is now adjusted and fiunctional for those that are interested:

<?php
session_start();
header("Cache-control: private"); //IE 6 Fix

$word=$_POST['word'];
$_SESSION[$word] = $word;

print_r ($_SESSION);
?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>I'm Gonna Lose It</title>
</head>

<body>
<br />
<br />
<br />
<FORM METHOD="POST" ACTION="thisone.php">
Word: <input type="text" name="word">
<input type="SUBMIT" value="Submit">
</FORM>
</body>
</html>

although it is no longer numeric... i needed to store directory/file name pointers across sessions, (i would do a str_replace ('/', '_', $string)) in the session array but sometimes needed to store a bunch simultaneously...

thanks,
i look forward to being part of the community here...

Okay, I misunderstood what you were trying to do.
I thought you had an array in the $_SESSION.

Congrats on figuring it out though, and welcome. 🙂
