jcbones Posted August 14, 2011 Share Posted August 14, 2011 How do you expect PHP held data to appear on a page without any PHP on it? index.php <?php session_start(); if(isset($_SESSION['ERRMSG_ARR'])) { $errors = implode('<br />',$_SESSION['ERRMSG_ARR']); }else { $errors = NULL; } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Login</title> <link href="loginmodule.css" rel="stylesheet" type="text/css" /> </head> <body> <h1>Login</h1> <form id="loginForm" name="loginForm" method="post" action="actions/login.php"> <table width="300" border="0" align="left" cellpadding="2" cellspacing="0"> <tr> <td width="112"><b>Email</b></td> <td width="188"><input name="email" type="text" class="textfield" id="email" /></td> </tr> <tr> <td><b>Senha</b></td> <td><input name="password" type="password" class="textfield" id="password" /></td> </tr> <tr> <td></td> <td><p><a href="resend_password.php">Esqueceu sua senha?</a></p></td> </tr> <tr> <td> </td> <td><input type="submit" name="Submit" value="Login" /> <?php echo $errors; ?></td> </tr> </table> </form> </body> </html> Link to comment https://forums.phpfreaks.com/topic/244775-problem-with-error-message-when-login/#findComment-1257289 Share on other sites More sharing options...
adhbvklwqdbviabjiawdnbij Posted August 14, 2011 Author Share Posted August 14, 2011 Thanks. I used: <?php session_start(); ?> and <?php if( isset($_SESSION['ERRMSG_ARR']) && is_array($_SESSION['ERRMSG_ARR']) && count($_SESSION['ERRMSG_ARR']) >0 ) { echo '<ul class="err">'; foreach($_SESSION['ERRMSG_ARR'] as $msg) { echo '<li>',$msg,'</li>'; } echo '</ul>'; unset($_SESSION['ERRMSG_ARR']); } ?> Link to comment https://forums.phpfreaks.com/topic/244775-problem-with-error-message-when-login/#findComment-1257303 Share on other sites More sharing options...
