Hello,

Right, so what I'm trying todo is have http://mysite.com/index.php as my main site splash page. Now on that splash page I have a login form. (Code is below.) What I need down is to hook it into a forum so it validates the login or not.

But if the login is incorrect it will go back to http://mysite.com/in...act=loginfailed

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
	<head>
		<title><?php echo $_SERVER["HTTP_HOST"] ; ?> :: Log In</title>
		<style type='text/css' media='all'>
			@import url('http://<?php echo $_SERVER["HTTP_HOST"] ;?>/main.css');
		</style>	
	</head>
	<body><p>&nbsp;</p>
		<form id='install-form' action='index.php' method='post'>
		<input type='hidden' name='_sd' value='b%3A0%3B'>
		<div id='ipswrapper'>
		    <div class='main_shell'>
		 	    <div id='navigation'>
					<ul id='section_buttons'>
						<li class='active'><span>Log In</span></li>

					</ul>				</div>
		 	    <div class='content_shell'>
		 	        <div class='package'>
		 	            <div>	            
    		 	        <div class='content_wrap'>
                <div style='clear:both'></div>      
				<h2> This Login system is still in the works.</h2>
				<input type='hidden' name='do' value='login' />
	<br />
	  <fieldset>
      <legend>Log In</legend>
		<div id='login_controls'>
			<label for='username'>Sign In Name</label>
			<input type='text' size='20' id='username' name='username' value='UserName'>

			<label for='password'>Password</label>
			<input type='password' size='20' id='password' name='password' value='PassWord'>      </div>
  </fieldset>
            		 	        <br />       		      <div style='float: right'>		 
			  <input type='submit' class='nav_button' value='Next >' />			
			  &nbsp;		
 </div> 		 	      								
    		 	            </div></div></div></div></div></div></form></body></html>

So in other words,

Fill in login form > Click next > Checks against a forums database if user/pass is valid > If not valid, goes back to index.php and shows an error. > But if valid, goes to a whole different file.

Have you seen this article here? Should do what you want. I've adapted the code a bit for you. If you need further help integrating with your script let me know.

<?php

/**
* initiate ipb functions
*/
$ipblink = new ipbAuthentication;

/**
  * logging a user in
  */
if(isset($_REQUEST['username']) && isset($_REQUEST['password']))
{
	$returnCode = $ipblink->doLogin();
	
    if( $returnCode == 'SUCCESS' )
    {
    	// login success, redirect.
    }
    else
    {
    	// login faile, display error
    	print $returnCode;
    }
}
else
{
    // no login details provided
}


class ipbAuthentication
{
    /**
     * initialisation function to setup IPSregistry
     */
    protected function init()
    {
        /**
         * Edit this path, to where you have your forum installed.
         */
        $forum_path = 'ipb303';

        /**
        * We will change directories so that proper directory is picked up
        */
        chdir( $forum_path );

        /**
        * Get some basic IPB files
        */
        define( 'IPB_THIS_SCRIPT', 'public' );
        require_once( $forum_path . '\initdata.php' );

        /**
        * Get IPB registry
        */
        require_once( IPS_ROOT_PATH . 'sources/base/ipsRegistry.php' );
        require_once( IPS_ROOT_PATH . 'sources/base/ipsController.php' );

        /**
         * initialise the ipsRegistry
         */
        $this->ipbRegistry    = ipsRegistry::instance();
        $this->ipbRegistry->init();
    }
    /**
     * logs a user in, username and password should be in $_REQUEST['username'] and $_REQUEST['password']
     */
    public function doLogin()
    {
        /**
         * call the initialisation function
         */
        $this->init();

        /**
         * get the IPB login handler wrapper
         */
        require_once( IPS_ROOT_PATH . 'sources/handlers/han_login.php' );

        /**
         * setup the handler class
         */
        $login  = new han_login( $this->ipbRegistry );
        $login->init();

        /**
         * verify the login and do any necessary tasks. form variables must be called 'username' & 'password'
         */
        $login->verifyLogin();
        
        return $login->return_code;
    }
}
?>

Never seen that article

.

Kinda confused tho, How would I add this into the html part of things?

<?php

/**
* initiate ipb functions
*/
$ipblink = new ipbAuthentication;

/**
  * logging a user in
  */
if(isset($_REQUEST['username']) && isset($_REQUEST['password']))
{
        $returnCode = $ipblink->doLogin();
        
    if( $returnCode == 'SUCCESS' )
    {
        // login success, redirect.
    }
    else
    {
        // login faile, display error
        print $returnCode;
    }
}
else
{
   // no login details provided
}


class ipbAuthentication
{
    /**
     * initialisation function to setup IPSregistry
     */
    protected function init()
    {
        /**

         */
        $forum_path = 'devforums';

        /**
        * We will change directories so that proper directory is picked up
        */
        chdir( $forum_path );

        /**

        */
        define( 'IPB_THIS_SCRIPT', 'public' );
        require_once( $forum_path . '\initdata.php' );

        /**

You'll need to change the form to point to the same page, something like this. You could always have the login script on a separate page. Depending on how complex you want this, IPBSDK for IPB3 might be a better option, it would have more functions and probably easier to use.

<?php

/**
* initiate ipb functions
*/
$ipblink = new ipbAuthentication;

/**
  * logging a user in
  */
  
if( isset($_POST['username']) && isset($_POST['password']) )
{
    $returnCode = $ipblink->doLogin();

    if( $returnCode == 'SUCCESS' )
    {
        // login success, redirect.
        header('Location: http://www.yoursite.com/diff_file.php');
    }
    else
    {
    	print $returnCode;
		exit();	
    }
}

class ipbAuthentication
{
    /**
     * initialisation function to setup IPSregistry
     */
    protected function init()
    {
        /**
         * Edit this path, to where you have your forum installed.
         */
        $forum_path = 'ipb303';

        /**
        * We will change directories so that proper directory is picked up
        */
        chdir( $forum_path );

        /**
        * Get some basic IPB files
        */
        define( 'IPB_THIS_SCRIPT', 'public' );
        require_once( $forum_path . '\initdata.php' );

        /**
        * Get IPB registry
        */
        require_once( IPS_ROOT_PATH . 'sources/base/ipsRegistry.php' );
        require_once( IPS_ROOT_PATH . 'sources/base/ipsController.php' );

        /**
         * initialise the ipsRegistry
         */
        $this->ipbRegistry    = ipsRegistry::instance();
        $this->ipbRegistry->init();
    }
    /**
     * logs a user in, username and password should be in $_REQUEST['username'] and $_REQUEST['password']
     */
    public function doLogin()
    {
        /**
         * call the initialisation function
         */
        $this->init();

        /**
         * get the IPB login handler wrapper
         */
        require_once( IPS_ROOT_PATH . 'sources/handlers/han_login.php' );

        /**
         * setup the handler class
         */
        $login  = new han_login( $this->ipbRegistry );
        $login->init();

        /**
         * verify the login and do any necessary tasks. form variables must be called 'username' & 'password'
         */
        $login->verifyLogin();
        
        return $login->return_code;
