BSkopnik Posted May 15, 2009 Share Posted May 15, 2009 Okay, im no master with php here... but i have a login script that i use and works fine as far as I know.. BUT this is my issue.. on this machine(host) i use firefox, logs in fine. try IE, doesn't work. tried ie on my laptop, worked fine. other users some can, some can't.

Porl123 Posted May 15, 2009 Share Posted May 15, 2009 When it doesn't work in IE, what does it return if it returns anything? Quote Link to comment https://forums.phpfreaks.com/topic/158317-login-issues/#findComment-835009 Share on other sites More sharing options...
PFMaBiSmAd Posted May 15, 2009 Share Posted May 15, 2009 Is your code attempting to use the ip address, user agent information, http_referer, or javascript? Have you validated the HTML of your form so that you can eliminate invalid HTML as the cause (some browsers and some versions of some browsers ignore HTML errors that would allow a form to work, which others don't.) Posting your form and the form processing code (all the relevant code that someone would need in order to duplicate the problem) would be the quickest way for someone to determine if the problem is within your code or is due to browser problems. And as Porl123 just asked, what exactly are the symptoms when it does not work?

BSkopnik Posted May 16, 2009 Author Share Posted May 16, 2009 Here is code for form. $error = $_GET['op']; ... <form method="post" action="login.php" name="LogIn"> <table border="0" cellpadding="0" cellspacing="0" width="100%" height="100%"> <? if ( $error == 'error') { echo "<tr><td colspan=\"2\" align=\"center\" valign=\"bottom\"><div class=\"postby\">ERROR: INCORRECT PASSWORD OR USERNAME</div></td></tr>\n"; } ?> <tr> <td align="center" valign="middle"> <table border="1" width="150" height="10%" cellpadding="0" cellspacing="2"> <tr> <td align="right"><div class="field">USERNAME:</div></td> <td> <input type="text" name="U_NAME" maxlength="15" size="7" style="background-color: #666666; color: #FFFFFF; border: none;" /> </td> </tr> <tr> <td align="right"><div class="field">PASSWORD:</div></td> <td> <input type="password" name="U_PASS" maxlength="20" size="7" style="background-color: #666666; color: #FFFFFF; border: none;" /> </td> </tr> <tr> <td colspan="2" align="center"> <input type="submit" name="DoLogIn" value="Log In" style="background-color: #999999; color: #FFFFFF; border: 1px solid #FFFFFF; align=center" /> </td> </tr> </table> </td> </table> </form> and the php <?php session_start(); /** * @author BSkopnik * @copyright 2009 */ require "global_data.php"; if ( $_POST["DoLogIn"] ) { $up_link = mysql_connect( $DB_HOST, $DB_UNAME, $DB_UPASS ) or die( mysql_error() ); mysql_selectdb( $DB_NAME ) or die( mysql_error() ); $name = stripslashes($_POST["U_NAME"]); $pass = stripslashes($_POST["U_PASS"]); $name = strtolower( $name ); $pass = strtolower( $pass ); $query = "SELECT * FROM users WHERE username='$name' and password='$pass'"; $result = mysql_query( $query ); $count = mysql_num_rows( $result ) or die( mysql_error() ); if ( $count == 1 ) { $logged = TRUE; $_SESSION["LoggedIn"] = $logged; $_SESSION["Name"] = $name; header("location:cp.php"); }else { header("location:index2.php?op=error"); } }else { echo "ERROR: Cannot access page. Please check your link and try again."; } ?> For alot of people ( in ie ) it justs kicks back saying wrong user/pass. even with right name password. EDIT: Had a typo for some code..fixed the typo.

PFMaBiSmAd Posted May 16, 2009 Share Posted May 16, 2009 What have you done to troubleshoot what it is doing? Have you done a print_r($_POST) to even see what is being sent from the form? It is likely that because you don't have any exit; statements after your header() redirects that when your code continues running on the page that it causes the incorrect operation and that the key ingredients are both which browser but also the speed of the Internet connection. At a minimum add an exit; statement after every header() redirect. And if that does not solve the problem, please post all of your page with the form and identify which file is which? Is the first piece of posted code really index2.php? Quote Link to comment https://forums.phpfreaks.com/topic/158317-login-issues/#findComment-835090 Share on other sites More sharing options...

BSkopnik Posted May 18, 2009 Author Share Posted May 18, 2009 Alright, i tried listing all the variables, will be posting my code now.. but, I had used isset( $_POST["DoLogIn"]) which seemed to fix some peoples issues to log in, but some still can't, and end up blank page. I'm stuck index2.php <?php if ( isset($_SESSION["LoggedIn"]) ) { session_destroy(); } /** * @author BSkopnik * @copyright 2009 */ $error = $_GET['op']; $today = date( "D F d"); ?> <html> <head> <title>TWC :: Login (<? echo $today; ?>)</title> <link rel='stylesheet' type='text/css' href='css/sheet.css' title='style' /> </head> <body bgcolor="White"> <form method="post" action="login.php" name="LogIn"> <table border="0" cellpadding="0" cellspacing="0" width="100%" height="100%"> <? if ( $error == 'error') { echo "<tr><td colspan=\"2\" align=\"center\" valign=\"bottom\"><div class=\"postby\">ERROR: INCORRECT PASSWORD OR USERNAME</div></td></tr>\n"; } ?> <tr> <td align="center" valign="middle"> <table border="1" width="150" height="10%" cellpadding="0" cellspacing="2"> <tr> <td align="right"><div class="field">USERNAME:</div></td> <td> <input type="text" name="U_NAME" maxlength="15" size="7" style="background-color: #666666; color: #FFFFFF; border: none;" /> </td> </tr> <tr> <td align="right"><div class="field">PASSWORD:</div></td> <td> <input type="password" name="U_PASS" maxlength="20" size="7" style="background-color: #666666; color: #FFFFFF; border: none;" /> </td> </tr> <tr> <td colspan="2" align="center"> <input type="submit" name="DoLogIn" value="Log In" style="background-color: #999999; color: #FFFFFF; border: 1px solid #FFFFFF; align=center" /> </td> </tr> </table> </td> </table> </form> </body> </html> login.php <?php session_start(); /** * @author BSkopnik * @copyright 2009 */ require "global_data.php"; if ( isset($_POST["DoLogIn"]) ) { $up_link = mysql_connect( $DB_HOST, $DB_UNAME, $DB_UPASS ) or die( mysql_error() ); mysql_selectdb( $DB_NAME ) or die( mysql_error() ); $name = stripslashes($_POST["U_NAME"]); $pass = stripslashes($_POST["U_PASS"]); $name = strtolower( $name ); $pass = strtolower( $pass ); /*$query = "SELECT * FROM users"; $result = mysql_query( $query ) or die( mysql_error() ); while ( $row = mysql_fetch_array($result)) { echo $row["username"] .

So like I said, I had played with showing the post vars, and session vars to make sure they were all setting correctly,and they were. Just can't seem to figure out why some peolpe are getting just a blank screen after clicking log in. Any help would be appreciated, thanks.
