Using Inline Php; <h1><font Color="000088">the Username <?php '.$username.' ?> Already Exists";</h1>
So basically my project is one where the user can log onto my website, and the page then checks if the ID and password are in my table in my microsoft access file. If the username and password are the same, the user continues, if it isnt, then it stays on the same page and says something like "username and/or password are incorrect" or something along the lines of that. the problem is right now im not sure how to make it say "ERROR username and/or password is incorrect" if the username and password dont match. Can someone help me with this? and also make sure if the username and password are correct that it goes to the next page, entitled searchpage.php here is the code Code: [Select] <html> <head> <style type="text/css"> </style> </head> <body style="text-align:center"> <div id='title'> </div> <?php print_r ($_POST) ; if if (isset($_POST['Login'])) { if(isset($_POST['username'])){ $username= $_POST['username'] ; } if(isset($_POST['password'])){ $TABLE= $_POST['password'] ; } $username = null ; $password = null ; $connection = odbc_connect('Olympics', '', ''); if (!$connection) {exit("Conection Failed: " . $connection);} $username = stripslashes($username); $password = stripslashes($password); $sql = "select * from users where users = '$username' and passwords = '$password'"; $rs=odbc_exec($connection,$sql); $count=odbc_num_rows($rs); if ($count == 1) { $_SESSION['loggedIn'] = "true"; header("Location: searchpage.php"); } else { $_SESSION['loggedIn'] = "false"; header("Location: index.php"); echo "Login failed" ; } } echo "<form action='index.php' method='post'> \n" ; echo" Please enter your username and password if you wish. <br/> \n" ; echo "Username: <input type='text' name='username' > \n " ; echo "Password: <input type='password' name='password' > \n" ; echo "<input type='submit' value='Login' name='Login'> <br/> \n" ; echo "<input type='submit' value='You may also continue you as a guest.'> \n" ; echo "</form>" ; ?> </body> </html> Hey all. another quick question. here is the output of my 2D array: Code: [Select] array(2) { ["folder.jpg"]=> array(2) { ["valid"]=> bool(true) ["error"]=> bool(false) } ["file.mp3"]=> array(2) { ["valid"]=> bool(true) ["error"]=> bool(false) } } how can i foreach my way into getting an iterator that points to the folder.jpg and file.mp3? as is now, i have something that looks like this: foreach($arr as $val){ var_dump($val) } the var_dump of $val is an *array*.

ISSUE. A User enters information into a form. If the 'username' is already taken, a 'message' in Red and with larger font-size will be returned, for example, "The username $username already exists." If the username is 'mattd' then the message should say, "The username mattd already exists." Within my php application, I have included 'inline html'. Here is part of the code: .... if (mysql_num_rows($query_run)==1) { // it will never = more than one because only //one user will or will not exist ?> <html> </body> <h1><font color="#FF0066">The username <?php echo $username; ?>already exists.</h1> </body> </html> <?php }else{ //start the registration process $query = "INSERT INTO `Names` VALUES .... 1. At one point I did get this: "The username mattd already exists." 2. But now I only get "The username already exists." I am not retrieving the $username variable. This screenshot is found he http://imgur.com/lIwLZ1G thanks. While we're on the subject, is there a way to ensure that the first letter of a name is captalized, and the rest lowercase? Or is this best handled later on, when the name is being used and called from the DB. PS: some of us comment are code as to WHAT we are doing because we're just not that good yet, and we need to explain it to ourselves. I use the Wholesale Suite Premium Prices plugin with WooCommerce. I have 6 specific wholesale roles out of 15 that I wish to hide two specific shipping methods from being selected for the 6 exceptions.

Hi, I used to be able to get the username of the user who was loggd onto the computer and use that as a session variable, so when they are on the intranet, they need not to add any data. The code I used to use was Code: [Select] $logon_name = basename($_SERVER['AUTH_USER']); Since I updated the webserver and put an up-to-date version of PHP on this no longer works. If you have any ideas, such as maybe using Javascript to get this variable and passing it to PHP... Your help is appreciated. Stuart I want to accomplish two things: save some server overhead and create a friendlier user experience. Thus, prior to form submission, the user should have the opportunity to check whether the chosen username is available. As I've begun researching the topic, I've discovered AJAX, Vue, and XMLHttpRequest alternatives.
Any suggestions and alternatives that would give me guidance would be appreciated.
Additionally, are there any characters that should be expressly prohibited from use in a username (or other input field) that could aid malicious hackers in causing harm to my website, database, and files?

I have a login index with session_start and register the user information with : Code: [Select] $_SESSION['user'] = $r['username']; $_SESSION['loggedin'] = true; In that index file, it echo the right username that's logged in. On the other files, it echo always "root". My other files are combined with - Header.php ( Start of validation of session ) - Page.php ( Validate again ) - Footer.php ( End the validation of footer ) All files have a session start and if not logged in redirects to index file to login again. The problem, somewhere I have an error that I can't discover.. Could you please help me ? Header.php Code: [Select] <?php session_start(); include("connect.php"); include("../inc/config.php"); if( isset($_SESSION['user']) and $_SESSION['loggedin'] == true){ ?> MY OWN CODE <?php } else{ Header("Location:index.php"); } ?> PAGE.PHP Code: [Select] <?php session_start(); if( isset($_SESSION['user']) and $_SESSION['loggedin'] == true){ ?> <?php include("header.php"); $session = session_decode(session_id()); $result = mysql_query("SELECT * FROM admutilizador WHERE id='$session'") or die(mysql_error()); $row = mysql_fetch_array($result); ?> MY OWN CODE <?php include("footer.php"); ?> <?php } else{ Header("Location:index.php"); } FOOTER.PHP Code: [Select] <?php session_start(); if( isset($_SESSION['user']) and $_SESSION['loggedin'] == true){ ?> MY OWN CODE <?php } else{ Header("Location:index.php"); } Can someone help me ? thanks in advance. P.S. I used a test session var $_SESSION['test'] = "TEST"; and it keeps the records in other pages. Using the $_SESSION['user'] = $r['username']; ( info from DB that returns the right username in the same page, echoing it in other pages always output root. Hope this test could help anyone too. |
