new thread:same code (User Login)

[toddg]

Hello:
things are getting much closer to actually working. <grin> This is the last thing I have to get done and I can call the project complete.

I am getting errors:
Fatal error: Call to undefined function: () in /validate.php on line 18

from this code:

<?php
session_start();

// Connects to sql server and logs in with username and password  

$dbconnect here 

// Selects all of the data from database 

$sql_text = "SELECT * FROM users WHERE usrName = '$formUsername' AND password = '$formPassword'";

// execute query 

$query = mysql_query($sql_text) or die (mysql_error());

// session checks and such 

$logged_in = "no";
session_register("logged_in");

if ($mysql_num_rows($query) != 1) {
$SESSION["logged_in"] = "no";
header("Location: ./sorry.html");
exit();
}
else {
$SESSION["logged_in"] = "yes";
header("Location: ./family/index.html");
exit();
}

?>

basically I need to accomplish three things on two different pages.
1) pass login credential from form and validate against a DB table..if valid redirect to index.html else redirect to sorry.html
2) protect each page...if someone is valid let them in else redirect to login.html
3) on another page check if valid, if yes show naviation.inc else ignore the include.

Anyone that can help me? I really appreciate it, I am looking forward to understanding this stuff better and also calling this project "done"!

Thanks in advance.

humm

// session checks and such 

$logged_in = "no"; 
session_register("logged_in"); 

chnage the above to

// session checks and such 

$logged_in = "no"; 
session_register("$logged_in"); 

try that

yeah that fixed your error, now you have a new error on line 22

fixe it.. you forgot your $ again

<?php 
session_start(); 

// Connects to sql server and logs in with username and password 

$dbconnect here 

// Selects all of the data from database 

$sql_text = "SELECT * FROM users WHERE usrName = '$formUsername' AND password = '$formPassword'"; 

// execute query 

$query = mysql_query($sql_text) or die (mysql_error()); 

// session checks and such 

$logged_in = "no"; 
session_register("$logged_in"); 

if ($mysql_num_rows($query) != 1) { 
$_SESSION["$logged_in"] = "no"; 
header("Location: ./sorry.html"); 
exit(); 
} 
else { 
$_SESSION["$logged_in"] = "yes"; 
header("Location: ./family/index.html"); 
exit(); 
} 
?> 

see if that helps

Fatal error: Call to undefined function: () in /validate2.php on line 22

using this code:

<?php
session_start();

// Connects to sql server and logs in with username and password

$dbconnect here

// Selects all of the data from database

$sql_text = "SELECT * FROM users WHERE usrName = '$formUsername' AND password = '$formPassword'";

// execute query

$query = mysql_query($sql_text) or die (mysql_error());

// session checks and such

$logged_in = "no";
session_register("$logged_in");

if ($mysql_num_rows($query) != 1) {
$SESSION["$logged_in"] = "no";
header("Location: ./sorry.html");
exit();
}
else {
$SESSION["$logged_in"] = "yes";
header("Location: ./family/index.html");
exit();
}

?>

do you think it is something weird with the session? anything else I should check?

Thanks

As far as I understand, you don't need to use session_register() if you are using the global $_SESSION variable, which is only available as a global variable in PHP 4.1.0 onwards...

I'm pretty sure you also don't need a '$' in the name of the variable you are registering when using the $_SESSION variable...

I could be wrong tho, I'm also very new to PHP 🙁
