Fatal error: Cannot redeclare logged_in()

[system]

I have been painstackinly over this code over a million trillon times. I have not found second instance of that function. Someone made a suggestion that I may be including a file that has the function redefined twice but I am not doing that either. All I am doing is including my function pages into an initialization file and then including the initialization in all my other files that need access to the functions. Well here is the code:

// functions page

[php]<?php

function logged_in(){

return (isset($_SESSION['id'])) ? TRUE : FALSE;

}

function update_users($update_data){

array_walk($update_data, 'array_sanitize');	

foreach($update_data as $fields => $data){
	
	$update[] = '`' .$field. '` = \'' .$data. '\'';

	
}

mysql_query("UPDATE `Users` SET " . implode(', ', $update) . " WHERE `id` = " . $_SESSION['id'] . "") or die(mysql_error());	

}

function register_users($register_data){

array_walk($register_data, 'array_sanatize');

$register_data['password'] = md5($register_data['password']);


$fields = '`' . implode('`, `', array_keys($register_data)) . '`';

$data = '\'' . implode('\', \'', $register_data) . '\'';

mysql_query(“INSERT INTO Users ($fields) VALUES($data)”);

$to = $register_data[‘email’];

$subject = ‘Activate your account’;

$body = “Hello {$register_data[‘first_name’]} ,\n\nYou need to activate your account, so paste the link below in the address bar:\n\nhttp://domain.co.cc/login/activate.php?email= {$register_data[‘email’]} $email_code= {$register_data[‘email_code’]} \n\n-domain”;

$header = ‘From: [email protected]’;

mail($to, $subject, $body, $header);

}

function activate($email, $email_code){

$email = mysql_real_escape_string($email);

$email_code = mysql_real_escape_string($email_code);


if(mysql_result(mysql_query("SELECT COUNT(`id`) FROM `Users` WHERE `email` = '$email' AND `email_code` = '$email_code' AND `active` = 0"), 0) == 1){
	
	mysql_query("UPDATE `Users` SET `active` = 1 WHERE `email` = '$email'");
	
	return TRUE;
	
}else{

	return FALSE;
	
}

}

function user_count(){

$query = mysql_query("SELECT COUNT(`id`) WHERE `active` = 1");	


return mysql_result($query, 0);

}

function user_exists($un){

$un = sanitize($un);

$query2 = mysql_query("SELECT COUNT(`id`) FROM `Users` WHERE `username` = '$un'");

return (mysql_result($query2, 0) == 1) ? TRUE : FALSE;

}

function email_exists($em){

$em = sanitize($em);


$query3 = mysql_query("SELECT COUNT(`id`) FROM `Users` WHERE `email` = '$em'");

return (mysql_result($query3, 0) == 1) ? TRUE : FALSE;

}

function user_active($un){

$un = sanitize($un);

$query4 = mysql_query("SELECT COUNT(`id`) FROM `Users` WHERE `username` = '$un' AND `active` = 1");

return (mysql_result($query4, 0) == 1) ? TRUE : FALSE;

}

function id_from_username($un){

$un = sanitize($un);

$query5 = mysql_query("SELECT `id` FROM `Users` WHERE `username` = '$un'");

return mysql_result($query5, 0, 'id');

}

function login($un, $pw){

$id = id_from_username($un);

$un = sanitize($un);

$pw = md5($pw);


$query6 = mysql_query("SELECT COUNT(`id`) FROM `Users` WHERE `username` = '$un' AND `password` = '$pw'");

return (mysql_result($query6, 0) == 1) ? $id : FALSE;

}

?>

//initialization file

<?php session_start(); //error_reporting(0); require 'database/connect.php'; require 'functions/users.php'; require 'functions/general.php'; if(logged_in() === TRUE){ $query = mysql_query("SELECT * FROM `Users` WHERE `id` = '".$_SESSION['id']."'") or die(mysql_error()); while($row = mysql_fetch_array($query)){ $usn = $row['username']; $paw = $row['password']; $first_name = $row['first_name']; $eml = $row['email']; $em_code = $row['email_code']; } } ?>[/php]

Hi Daniel,

I don’t see the problem in this code. I would start by commenting out each of your required files and see if you still get the error. If it goes away, uncomment them one at a time until you get the error again and that should tell you where to look. When you check these files, make sure that you also watch for any included or required files that they may be using.

Does the error indicate that it is being thrown in this file or a different one? If it is this one, then the function is being declared prior to this file’s inclusion and you will need to look for includes or the actual function in the page that is using this file.

This isn’t necessarily the best solution, but if you don’t find it anywhere else, and the error is being generated by the file you attached, you could do something like the following instead:[php]if(!function_exists(‘logged_in’)) {
function logged_in(){
return (isset($_SESSION[‘id’])) ? TRUE : FALSE;
}
}[/php]

This will check for the function before attempting to declare it.
