Hallo all... I need some assistance and guidance for creating the login (should be simple but I'm a newbie)... Well I'm using the follownig form in a page called login.php <form action="index.php" method="POST" onsubmit="return validation();"> <tr align="left"> <td><label class="admin_login_text">username</label></td> <td><input type="text" id="admin_user" /></td> </tr> <tr align="left"> <td><label class="admin_login_text">password</label></td> <td><input type="password" id="admin_pass" /></td> </tr> <tr> <td colspan="2"> <br /><input type="image" src="images/buttons/login_btn.png" value="Submit" class="login_btn" id="login_btn" /> </td> </tr> </form> which form is checked by a javascript function to check if the fields are empty, and then with Ajax to check from the db if the username and password are correct : function validation(){ document.getElementById('error_message_div').innerHTML= ''; var returnFlag; user = document.getElementById("admin_user").value; password = document.getElementById("admin_pass").value; if (user == ''){ document.getElementById('error_message_div').innerHTML += '<tr><td colspan="2"><div class="error_message">Please ender a username</div></td></tr>'; returnFlag = "no"; } else if (password == ''){ document.getElementById('error_message_div').innerHTML += '<tr><td colspan="2"><div class="error_message">please enter a password</div></td></tr>'; returnFlag = "no"; } else { returnFlag = "yes"; } httpObject = ajaxObject(); if (httpObject != null) { file_url = "includes/check_the_login.php?user="+user+"&password="+password; httpObject.open("GET" ,file_url, true); httpObject.send(null); check = setOutput(); //alert('check = ' + check); if(!check){ returnFlag = 'yes'; } if(check){ document.getElementById('error_message').innerHTML = httpObject.responseText; returnFlag = 'no'; } } if (returnFlag == 'yes'){ return true; }else{ return false; } } function ajaxObject() { var xmlhttp; if (window.XMLHttpRequest) { return xmlhttp=new XMLHttpRequest(); } else if (window.ActiveXObject) { return xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } else { alert("Your browser does not support XMLHTTP! <br> XMLHTTP is necessary for AJAX. Please update your browser."); } } function setOutput(){ //alert("set output"); if(httpObject.readyState == 4){ //alert('httpObject.responseText : ' + httpObject.responseText); if(httpObject.responseText == 'False'){ return false; } else{ return true; } } } The php file ('check_the_login.php?') crreates a session and stores the usename and start time values in it, if the username and pass are ok. I should also mention that the index checks if the sessions username value is set, and the start time value: <?php session_start(); $inactive = 60; // check to see if $_SESSION['timeout'] is set if(isset($_SESSION['timeout']) ) { $session_life = time() - $_SESSION['start']; if($session_life > $inactive) { session_destroy(); } } $_SESSION['timeout'] = time(); if (!isset($_SESSION['uname'])){ header("Location: login.php?warning_type=1"); } echo '<br /><b>Dude ' . $_SESSION['uname'] . ' ' . $_SESSION['start']. '</b>'; ?> My problem is that in ie it works fine, but in mozilla it doesn't. In mozilla, it executes the ajax part but the index page always redirects it back to login. What I noticed is that if I alert the massages you see in the setOutput function, it works fine. Also if I comment the header (in the index page) that makes the redirection, I notice that in the first load of index it doesn't echo the session values, but when I refresh the page it does... Hope you understood my question... Any suggestions??? Thanks!!!
