Hi All,

First of all, apologies on the lengthy code. It's a detailed form.

I have the below code with is my form. Currently, I have a session which identify's whether the user has logged in successfully. My issue is that I want to run another session which stores the entered form data temporarily. This form goes to a validation page which asks the user to go back and make any changes if they caused an error, otherwise, the form information gets stored in a mysql database.

If you can advise or provide a example, it would be greatly appreciated.

 

<?php
session_start();
$MM_authorizedUsers = "";
$MM_donotCheckaccess = "true";

// *** Restrict Access To Page: Grant or deny access to this page
function isAuthorized($strUsers, $strGroups, $UserName, $UserGroup) { 
  // For security, start by assuming the visitor is NOT authorized. 
  $isValid = False; 

  // When a visitor has logged into this site, the Session variable MM_Username set equal to their username. 
  // Therefore, we know that a user is NOT logged in if that Session variable is blank. 
  if (!empty($UserName)) { 
    // Besides being logged in, you may restrict access to only certain users based on an ID established when they login. 
    // Parse the strings into arrays. 
    $arrUsers = Explode(",", $strUsers); 
    $arrGroups = Explode(",", $strGroups); 
    if (in_array($UserName, $arrUsers)) { 
      $isValid = true; 
    } 
    // Or, you may restrict access to only certain users based on their username. 
    if (in_array($UserGroup, $arrGroups)) { 
      $isValid = true; 
    } 
    if (($strUsers == "") && true) { 
      $isValid = true; 
    } 
  } 
  return $isValid; 
}

$MM_restrictGoTo = "login.php";
if (!((isset($_SESSION['MM_Username'])) && (isAuthorized("",$MM_authorizedUsers, $_SESSION['MM_Username'], $_SESSION['MM_UserGroup'])))) {   
  $MM_qsChar = "?";
  $MM_referrer = $_SERVER['PHP_SELF'];
  if (strpos($MM_restrictGoTo, "?")) $MM_qsChar = "&";
  if (isset($QUERY_STRING) && strlen($QUERY_STRING) > 0) 
  $MM_referrer .= "?" . $QUERY_STRING;
  $MM_restrictGoTo = $MM_restrictGoTo. $MM_qsChar . "accesscheck=" . urlencode($MM_referrer);
  header("Location: ". $MM_restrictGoTo); 
  exit;
}
?>

Quick and dirty example:

 

 

form.php

<?php
   session_start();
  
   // echo out errors. Nothing will echo out if first time visit
   foreach($_SESSION['errors'] as $error) {
      echo "$error <br />";
   } // end foreach error
   unset($_SESSION['errors'];

// echo out form. Default values previous entered in stuff if applicable
echo <<<FORMENT
<form action = 'process.php' method = 'post'>
   First Name:<input type = 'text' name = 'fname' value = '{$_SESSION['fname']}'> <br />
   Last Name:<input type = 'text' name = 'lname' value = '{$_SESSION['lname']}'> <br />
   <input type = 'submit' value = 'submit'>
</form>
FORMENT;

?>

 

process.php

<?php
   session_start();
   
   // check to see if fname was filled out. If not...
   if(!$_POST['fname'] || (trim($_POST['fname']) == '')) {
      // make an error msg session array
      $_SESSION['errors'][] = "Need to fill out first name.";
   // if filled out...
   } else {
      // create a session var for fname
      // also might want to sanitize...
      $_SESSION['fname'] = $_POST['fname'];
   } // end if..else fname

   // check to see if lname was filled out. If not...
   if(!$_POST['lname'] || (trim($_POST['lname']) == '')) {
      // make an error msg session array
      $_SESSION['errors'][] = "Need to fill out last name.";
   // if filled out...
   } else {
      // create a session var for lname
      // also might want to sanitize...
      $_SESSION['lname'] = $_POST['lname'];
   } // end if..else lname

   // if there are errors...
   if($_SESSION['errors']) {
      // send user back to form
      header("Location: form.php");
   // if no errors generated...
   } else {
      // insert into db code here.  
   } // end if..else errors
?>
