Hi, I am new to php and I am totally lost on what steps I need to take in order to create a website that will allow a user to login with an email address and password or subscribe or unsubscribe. if they choose to subscribe then they should be directed to a contact form to enter additional information and if they unsubscribe they should receive an email stating that they successfully unsubscribed. They should also be given the option of logging out and destroying the session...can someone please help me or lead me in the right direction. Thank you so much for you help. This is what I have so far:

<html> 

<head>
<title>A Girl's World</title>

<form name="input" action="p5direct.php" method="post">
<body background="kenya.jpg">
<p align="center"><font size="5">The World According to a Diva</font></p>

if(isset($_POST['submit']))

$table_name = 'subscribers';

$pattern = "/^[a-zA-Z0-9._-]+@[a-zA-Z0-9-]+\.[a-zA-Z.]{2,5}$/";

$connect = mysql_connect($server, $user, $datapassword) or die ("Could Not Connect!");
mysql_select_db($database, $connect) or die ("Could Not Connect!");

        $SQLcmd = mysql_query("Select email FROM subscribers WHERE email='$email'");
        $count = mysql_num_rows($SQLcmd);

        if ($count!=0)

        {
           die("That email has  already been used ");
         }  

    if ($subchoice == subscribe)
    {
       if (preg_match($pattern, $email))
       { 
       echo "<font color='red'>The Email Field contains invalid characters.</font><br>"; 
       } 

          elseif (strlen($password)<6)
        {

        }
          elseif (!preg_match("$ddmmyyy", $date)) 
          {
         echo " <font color='red'>Invalid format for DOB</font>";
          }
          else{
         $queryreg = mysql_query("

        ");

        die("You have been registered!");
       }

Hey shawtyred74,

Your second code isn't properly wrapped in code tags. The problem is the opening brace to the ending code wrapper.

Instead of [/CODE], you have /CODE]

my if else statements dont seem to work correctly in the last code I posted

0

thanx so much...I didnt relaize that so I corrected that but I am getting a parse error at line 85 and I have no code past line 83 so i am totally confused.. :(

When you get an error on the last line of the program (or even beyond as in this case),
it means that PHP has gone through the module expecting to find a closing brace/bracket (or sometimes a closing quote) and it didn't find it.

In this case, it looks as if the IF statement on line 10 needs a closing brace (maybe on line 13). If you consistently indent your code, it makes it easier to find it.

Thank you, I think I closed all my curly braces but I a still getting an error. Do you happen to see any errors I am missing...

I am trying to have a session in my code so I can use session destroy when the user logs out

0

is this code for welcome.php? I cannot find userid anywhere in the code!
It is strange that PHP complains about something non existant!

oh I am sorry I copied the other code I was trying....here is my code:

<?php 
session_start(); 
ob_start();
$_SESSION["userid"]=session_id();
?>



<?php

if(isset($_POST['login'])) 
{
$login = $_POST['login'];

$emailad = $_POST['email'];
$passwd = $_POST['password'];
$server = 'localhost';
$user = 'root';
$datapassword = '';
$database = 'km';
$table_name = 'subscribers';

$pattern = "/^[a-zA-Z0-9._-]+@[a-zA-Z0-9-]+\.[a-zA-Z.]{2,5}$/";
$pattern2 = '/[A-Z[:space:].|@|-|,|$|!|?|%|!]/';

if(session_id()==$_SESSION["userid"]){
if ($emailad && $passwd)	{
  $connect = mysql_connect($server, $user, $datapassword) or die ("Could Not Connect!");
  mysql_select_db($database, $connect) or die ("Could Not Connect!");
  
  $SQLcmd = "SELECT * FROM $table_name WHERE email='$emailad' AND password='$passwd'"; 
  $query = mysql_query($SQLcmd);
  $numrows = mysql_num_rows($query);
  if($numrows != 0)	{
   while ($row = mysql_fetch_array($query))
   {  $dbemail = $row['email'];
      $dbpassword = $row['password'];  }
   if ($emailad == $dbemail && $passwd == $dbpassword)	{   
     //$_SESSION['username'] = $username; 
     $_SESSION['unerror']="";
     //header( "Location: program1.php" );  
	 }
   else {  
     echo "<font color='red'>Invalid Password, Please Try Again!!!</font>";
	 	} }
 else  {
     echo "<font color='red'>That user does not exist!!!</font>";
     	} }

What is function of this line? AFAIK it is useless!

if(session_id()==$_SESSION["userid"])

EDIT:
I would make an Authentication class and in it put method that check if user is login then do something like

if($AuthObj->isLoggedIn()){
   //user is logged in do stuffs
}else{
    //redirect user to login page or out errors
}

I added that line because I was trying to create a session so when the user logs out it will destroy the session...was I headed in the wrong direction

Just use:

if(isset($_SESSION['userid'])){
