PHP - Login Screen Help
I have a login screen that only partly works if i put in the password and click submit it gives me a 500 internal server error. but if i put in the wrong password it gives me the wrong password screen. i am new to this and lost as to why it doesn't work any help would be appreciated. i am running on vista with iis7 and mysql. also this is some code i found online and changed it around to fit the new php 5.3.6 so not sure what i did or if i need to change more. Thank you in advance
Similar TutorialsHello and ty all for helping I have located the problem its in login.php file but dont know where thats why am turning to experts of coding. My file is located here ftp.sofo.si username and password are same "guest" pls feel free to download and inspect Thank you again for any help cheers For my site I need to screenscrape a page on a site. The problem is, to access the page that contains the data I need, I have to login to my account first. I know there are ways to simulate a form submission with ASP, but my server is Linux and can't use ASP. I'm wondering if any of you know how I would be able to simulate a POST with something like cURL? And possibly write an example script? Thanks in advance. (This may be in the wrong section, please move it if it is. Thanks) I have a little php site that looks up data in my crm database quickly and easily on my iphone. Right now it's wide open because I'm in and out of it all day and trying to input uid/pw into a secure login page is a pain in the rear. (we're not talking about sensitive data here and I'm the only user.) So, I would like to design a screen with several large graphic buttons and be able to touch those buttons in a specific sequence that would functionally allow a secure login. Similar in concept to the android screen lock. You touch a sequence of numbered buttons and voila, the screen unlocks. It does not open a text field for data entry into two separate fields. So if my access code was 1,2,3,4 and the screen was divided into quarters with a large number on each one, I would touch the buttons in that order and it would open the main page. How would this best be accomplished? Is there a php function to essentially build a variable through successive key presses? then with a final submit it would just check that against a "secret code" and allow access. Thanks for any input. hi i need help an idea how can i separate members from admins since i dont know how to create login form i used tutorial ( http://www.youtube.com/watch?v=4oSCuEtxRK8 ) (its session login form only that i made it work other tutorials wre too old or something) how what i want to do is separate members and admins because admin need more rights to do now i have idea but dont know will it work like that what i want to do is create additional row in table named it flag and create 0 (inactive user) 1 (member) 2 (admin) will that work? and how can i create different navigation bars for users and admins? do you recommend that i use different folders to create it or just script based on session and flag? Hi guys. What I want to create is really complicated. Well I have a login system that works with post on an external website. I have my own website, but they do not give me access to the database for security reasons, therefore I have to use their login system to verify my users. What their website does is that it has a post, with username and password. The POST website is lets say "https://www.example.com/login". If login is achieved (i.e. username and password are correct), it will redirect me to "https://www.example.com/login/success" else it will redirect me to "https://www.example.com/login/retry". So I want a PHP script that will do that post, and then according to the redirected website address it will return me TRUE for success, FALSE for not successful login. Any idea?? Thanks Hi guys, Can anyone assist me. I am trying to create a login for admin and user (if user not a member click register link) below is my code: But whenever I enter the value as: Username: admin Password:123 - I got an error message "That user does not exist!" Any suggestion and help would be appreciated. Thanks. login.php <?php //Assigned varibale $error_msg as empty //$error_msg = ""; session_start(); $error_msg = ""; if (isset($_POST['submit'])) { if ($a_username = "admin" && $a_password = "123") { //Define $_POST from form text feilds $username = $_POST['username']; $password = $_POST['password']; //Add some stripslashes $username = stripslashes($username); $password = stripslashes($password); //Check if usernmae and password is good, if it is it will start session if ($username == $a_username && $password == $a_password) { session_start(); $_SESSION['session_logged'] = 'true'; $_SESSION['session_username'] = $username; //Redirect to admin page header("Location: admin_area.php"); } } $username = (isset($_POST['username'])) ? $_POST['username'] : ''; $password = (isset($_POST['password'])) ? $_POST['password'] : ''; if($username && $password) { $connect = mysql_connect("localhost", "root", "") or die ("Couldn't connect!"); mysql_select_db("friendsdb") or die ("Couldn't find the DB"); $query = mysql_query ("SELECT * FROM `user` WHERE username = '$username'"); $numrows = mysql_num_rows($query); if ($numrows != 0){ while ($row = mysql_fetch_array($query)) { $dbusername = $row['username']; $dbpassword = $row['password']; } //Check to see if they are match! if ($username == $dbusername && md5($password) == $dbpassword) { header ("Location: user_area.php"); $_SESSION['username'] = $username; } else $error_msg = "Incorrect password!"; //code of login }else $error_msg = "That user does not exist!"; //echo $numrows; } else $error_msg = "Please enter a username and password!"; } ?> <!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 Page</title> </head> <body> <br /> <?php require "header.php"; ?><br /> <div align="center"> <table width="200" border="1"> <?php // If $error_msg not equal to emtpy then display error message if($error_msg!="") echo "<div id=\"error_message\"style=\"color:red; \">$error_msg</div><br />";?> <form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post"> <!--form action="login_a.php" method="post"--> Username: <input type="text" name="username" /><br /><br /> Password: <input type="password" name="password" /><br /><br /> <input type="submit" name = "submit" value="Log in" /> </form> <p> </p> Register a <a href="register.php">New User</a> </table> </div> </body> </html> Hello guys, Is there on web any updated tutorial on how can I add Facebook login on my simple php login script?

Ok, I know how to screen scrape, but I don't know how to screen scrape when there is a login. I've looked this up for awhile, but no luck. I'd like to also make it so I can execute a url when I am logged in on the script for the script, for an example execute this url: http://site.com/data.php?id=9912&submit=1 Thanks in advanced.

Hi, Im trying to work out a way to get the New York Lottery's Take 5 results. Theres a few sites that list the winning numbers, i assume automatically as there is alot of lottery games on these sites. what would be the best way to get this? http://www.myfreepost.com/lottery/index.php/us/newyorklottery/takefive/result/ http://www.elite-lottery-results.com/?action=view_game&gid=NY2 Hi, I need some basic video capturing features. So I want to ask, is there any way, library or work-round for recording browser screen in a video file using PHP? Thanks in Advance. Hello.
The first page works, but when form actioning to the next i just get a white screen.
This is the white screen page:
<?php session_start(); include 'details.php'; $username = $_POST['username']; $password = $_POST['password']; $pwswdrd = md5($password); if(!empty($_POST['username'])) { $query = mysqli_query($con, "SELECT * FROM users where name = '$username' AND pass = '$pwswdrd'") or die(mysqli_connect_error()); $row = mysqli_fetch_array($query); if(!empty($row['name']) AND !empty($row['pass'])) { $_SESSION['username'] = $row['username']; $_SESSION['id'] = $row['id']; header('Location: index.php'); } } else { echo "You failed to log in."; } ?> - details.php <?php $one=mysqli_connect('.......webhost.com','aee','aaa') or die("Failed to connect to MySQL: " . mysqli_error() ); $db=mysqli_select_db($one,'aee') or die("Failed to connect to MySQL: " . mysqli_error() ); ?> -- What can possibly be wrong?! I am using file_get_contents with a url (http) to screen scrape certain web pages that are publicly accessible. However there are certain web pages (https) that require me to use an x509 certificate stored in my browser to make them visible. I would like to scrape them too. How would I scrape them using a php script? Thanks in Advance. so im working on building a forum and i got everything on it but when you go to add a reply to the topic and click the reply button it will just go to a blank screen Not sure why its doing this, never had this problem. heres the code with the button Code: [Select] <?php require("top.php"); if ($username && ($_GET['cid'] == "")) { header("Location: home.php"); exit(); } $cid = $_GET['cid']; $tid = $_GET['tid']; ?> <div id='homepageright'> <form action="post_reply_parse.php" method="post"> <p>Reply Comment</p> <textarea name="reply_content" rows="5" cols="75"></textarea> <br /><br /> <input type="hidden" name="cid" value="<?php echo $cid; ?>" /> <input type="hidden" name="tid" value="<?php echo $tid; ?>" /> <input type="submit" name="reply_submit" value="Reply" /> <div id='homepageleft'> </div> </div> </html> </body> and code the button goes to Code: [Select] <?php if($username){ header("Location: index.php"); } if(isset($_POST['reply_submit'])){ include_once("scripts/connect.php"); $creator = $_SESSION['uid']; $cid = $_POST['cid']; $tid = $_POST['tid']; $reply_content = $_POST['reply_content']; $sql = "INSERT INTO post (category_id, topic_id, post_creator, post_content, post_date) VALUES ('".$cid."', '".$tid."', '".$creator."', '".$reply_content."', now())"; $res = mysql_query($sql) or die(mysql_error()); $sql2 = "UPDATE categories SET last_post_date=now(). last_user_posted='".$creator."'

Here's what I'm trying to do. Administrator clicks on Add New Item to Inventory, pulling up the shops that are available to add inventory to. (This part appears to be working, because it does list those shops available). Then, the administrator will click on a shop name, opening up a form that will allow them to type in the name of the item they want to add. Instead, it goes to a blank screen, no errors even with error reporting on. adminpanel.php is the main file that houses all these functions. If you're familiar with EZRPG, it's the same basic setup, just with these additions to the list. Any help would be greatly appreciated! Thank you!! function addinv() { $query = doquery("SELECT id,name FROM shop ORDER BY name", "shop"); $page = "<b><u>Add Inventory</u></b><br />Click to add an item to a shop's inventory.<br /><br /><table width=\"50%\">\n"; $count = 1; while ($row = mysql_fetch_array($query)) { if ($count == 1) { $page .= "<tr><td width=\"8%\" style=\"background-color: #eeeeee;\">".$row["id"]."</td><td style=\"background-color: #eeeeee;\"><a href=\"admin_panel.php?do=addshopinv:".$row["id"]."\">".$row["name"]."</a></td></tr>\n"; $count = 2; } else { $page .= "<tr><td width=\"8%\" style=\"background-color: #ffffff;\">".$row["id"]."</td><td style=\"background-color: #ffffff;\"><a href=\"admin_panel.php?do=addshopinv:".$row["id"]."\">".$row["name"]."</a></td></tr>\n"; $count = 1; } } if (mysql_num_rows($query) == 0) { $page .= "<tr><td width=\"8%\" style=\"background-color: #eeeeee;\">No items found.</td></tr>\n"; } $page .= "</table>"; admindisplay($page, "Add Shop Inventory"); } function addshopinv($name) { if (isset($_POST["submit"])) { extract($_POST); $errors = 0; $errorlist = ""; if ($name == "") { $errors++; $errorlist .= "Name is required.<br />"; } else if ($errors == 0) { $query1 = doquery("SELECT * FROM items WHERE name=$name"); $item_id = mysql_fetch_array($query1); $query = doquery("INSERT INTO `sale` SET shop_id=".$row["id"].", item_id='$item_id',"); admindisplay("Inventory Item Added.","Add New Inventory Item"); } else { admindisplay("<b>Errors:</b><br /><div style=\"color:red;\">$errorlist</div><br />Please go back and try again.", "Add New Item to Shop"); } } $name = $page = <<<END <b><u>Add New Inventory Item</u></b><br /><br /> <form action="admin_panel.php?do=addshopinv:$name" method="post"> <table width="90%"> <tr><td width="20%">Name:</td><td><input type="text" name="name" size="30" maxlength="255" value="" />*255 character max</td></tr> </table> <input type="submit" name="submit" value="Submit" /> <input type="reset" name="reset" value="Reset" /> </form> END; $page = parsetemplate($page, $row); admindisplay($page, "Add New Inventory Item"); } Hello! Incredibly new to PHP, so if this problem is a clear error i apologise. I am developing a page which will display a product based on what is clicked as a result of a search, my problem is that no matter that happens I cannot display anything from the Products table in my database: Code: [Select] <?php session_start(); include "connect.php"; $prodsql="SELECT product_ID, product_Name, Category, Price, Information from Product ;"; $prodresult = mysqli_query($_SESSION['conn'], $prodsql); while ($prow = mysql_fetch_array($prodresult, MYSQL_NUM)) { echo "<p> $prow['product_Name']"; } else{ } What am i missing? The connect.php works as I can successfully login and register members. Thank you |
