Help with passing variables

Recommended Posts

Howdy everyone.

I am having trouble passing a $_GET variable. It is "getting" it correctly but it wont pass it to next site.

Here is my code that I am trying to get to work. Now when I pass this I get a error that says.

[quote]You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1[/quote]

[code]$id = $_GET['id_eve'];
$MM_redirectLoginSuccess = "calenderedit.php?id_eve=$id";[/code]

Here is the scenario...

I have a dynamic calendar view page, it loads id_eve and grabs the correct information from the database. I have a "Login to Edit" form at the bottom of the page. Which is what the redirectLoginSuccess variable is for. Now when I hit the sumbit form information button it send me to the site but it just has "calenderedit.php?id_eve=" in the address bar but no variable....

Can you help? BTW I have all my code like this above the html tags.

No that didnt work. *sigh*

Here is my whole code.

[code]<?php require_once('Connections/calendar.php'); ?>
$colname_Recordset1 = "-1";
if (isset($_GET['id_eve'])) {
  $colname_Recordset1 = (get_magic_quotes_gpc()) ? $_GET['id_eve'] : addslashes($_GET['id_eve']);
mysql_select_db($database_calendar, $calendar);
$query_Recordset1 = sprintf("SELECT * FROM rsCalendar WHERE id_eve = %s", $colname_Recordset1);
$Recordset1 = mysql_query($query_Recordset1, $calendar) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);
// *** Validate request to login to this site.
if (!isset($_SESSION)) {
$id = $_GET['id_eve'];
$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($_GET['accesscheck'])) {
  $_SESSION['PrevUrl'] = $_GET['accesscheck'];

if (isset($_POST['email'])) {
  $MM_fldUserAuthorization = "";
  $MM_redirectLoginSuccess = "calenderedit.php?id_eve=".$id;
  $MM_redirectLoginFailed = "calender.php";
  $MM_redirecttoReferrer = false;
  mysql_select_db($database_calendar, $calendar);
  $LoginRS__query=sprintf("SELECT user_email, user_pass FROM rsCalendar_users WHERE user_email='%s' AND user_pass='%s'",
    get_magic_quotes_gpc() ? $loginUsername : addslashes($loginUsername), get_magic_quotes_gpc() ? $password : addslashes($password));
  $LoginRS = mysql_query($LoginRS__query, $calendar) or die(mysql_error());
  $loginFoundUser = mysql_num_rows($LoginRS);
  if ($loginFoundUser) {
    $loginStrGroup = "";
    //declare two session variables and assign them
    $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;      

    if (isset($_SESSION['PrevUrl']) && false) {
      $MM_redirectLoginSuccess = $_SESSION['PrevUrl'];
    header("Location: " . $MM_redirectLoginSuccess );
  else {
    header("Location: ". $MM_redirectLoginFailed );

I tried doing $id = echo $_GET['id_eve']; and that was a syntax error... I thought I would give it a try anyways.

Ok, Well since that is giving me trouble. I had another idea.

I know in PHP you can have modules that are shown depending on certain situations. Can I make a module that after the person logs in, it "unlocks" a module so the person can access that module?

If that is possible can anyone give me resources on how to do it?
