Session not being started

Akenatehm · September 29, 2010

Hey Guys,

Im having a really frustrating problem with this set of PHP:

writeConversationFunctions.php

<?php
session_start();
the function writeMessage($message){
$_SESSION['messagetest'] = $message;
$chatLogFile = "log.txt";
$openChatLog = fopen($chatLogFile, 'w') or die("Failed to open Log File.");
if($message == "resetnow"){
	$message = "";
	fwrite($openChatLog, $message);	
	fclose($openChatLog);
	$_SESSION['lastMessageSize'] = 0;
}	
elseif($message == ""){
	}
else{
	$timestamp = date("h:i"); 
	if(isset($_SESSION['username'])){
		$username = $_SESSION['username'];
	}
	else{
		$username = "Anonymous";
	}
	if($message[0] == "/"){
		$commandString = stripslashes($commandString);
		$commandString = htmlentities($commandString, ENT_QUOTES, 'UTF-8');
		$commandString = substr($commandString, 1);
		$command = explode(" ",$commandString);
		switch ($command[0]){
			case "slap":
				$name = command[1];
				$commandResponse = '<p class="commandText">' ."You slap " . $name . "across the face.</p>";
				fwrite($openChatLog, $commandResponse);
				fclose($openChatLog);
			break;
		}
	}
	else{
		$message = stripslashes($message);
		$message = htmlentities($message, ENT_QUOTES, 'UTF-8');
		$message = preg_replace('@(https?://([-\w\.]+)+(:\d+)?(/([\w/_\.]*(\?\S+)?)?)?)@', '<a href="$1" target="_blank">$1</a>', $message);
		$messageString = '
		<p class="message">
			<span class="timestamp">' .$timestamp . '</span>
			<span class="username">' . $username . ': </span>' 
			. $message .
		'</p>';
		fwrite($openChatLog, $messageString);
		fclose($openChatLog);
	}
}
}


writeMessage($_POST['message']);
?>

Simply, the session at the top will not be created for some reason.

The post data is sent from:

index.php

<?php
session_start();
?>

Any help with this issue would be GREATLY appreciated!

Put

echo session_id();

to see if it is started.

Akenatehm · September 29, 2010

Okay, a session ID is being echoed. So the session must be starting succesfully?

That first file should be giving you a parse error. Do you have display_errors = On?
