  • Problem carrying Session over to other pages

    - by AAA
    I am able to login a user, but while processing to the next page (memebers area) I can't display any user info let alone print the $_SESSION[email]. I am not sure what's up. Below is the login code and the testing members are page. Login page: session_start(); //also in a real app you would get the id dynamically $sql = "select `email`, `password` from `accounts` where `email` = '$_POST[email]'"; $query = mysql_query($sql) or die ("Error: ".mysql_error()); while ($row = mysql_fetch_array($query)){ $email = $row['email']; $secret = $row['password']; //we will echo these into the proper fields } mysql_free_result($query); // Process the POST variables $email = $_POST["email"]; //Variables $_SESSION["email"] = $_POST["email"]; $secret = $info['password']; //Checks if there is a login cookie if(isset($_COOKIE['ID_my_site'])) //if there is, it logs you in and directes you to the members page { $email = $_COOKIE['ID_my_site']; $pass = $_COOKIE['Key_my_site']; $check = mysql_query("SELECT email, password FROM accounts WHERE email = '$email'")or die(mysql_error()); while($info = mysql_fetch_array( $check )) { if (@ $info['password'] != $pass) { } else { header("Location: home.php"); } } } //if the login form is submitted if (isset($_POST['submit'])) { // if form has been submitted // makes sure they filled it in if(!$_POST['email'] | !$_POST['password']) { die('You did not fill in a required field.'); } // checks it against the database if (!get_magic_quotes_gpc()) { $_POST['email'] = addslashes($_POST['email']); } $check = mysql_query("SELECT email,password FROM accounts WHERE email = '".$_POST['email']."'")or die(mysql_error()); //Gives error if user dosen't exist $check2 = mysql_num_rows($check); if ($check2 == 0) { die('That user does not exist in our database. <a href=add.php>Click Here to Register</a>'); } while($info = mysql_fetch_array( $check )) //gives error if the password is wrong if (@ $_POST['password'] != $info['password']) { die('Incorrect password, please try again'); } else { // if login is ok then we add a cookie $_POST['email'] = stripslashes($_POST['email']); $hour = time() + 3600; setcookie(ID_my_site, $_POST['email'], $hour); setcookie(Key_my_site, $_POST['password'], $hour); //then redirect them to the members area header("Location: home.php"); } } } else { // if they are not logged in ?> <?php } ?> home.php session_start(); if(!isset($_SESSION['email'])) { header('Location: login_test3.php'); die('<a href="login_test3.php">Login first!</a>'); } //Variables $_SESSION["email"] = $email; print $_SESSION['name']; UPDATE Just realized the existing code gets in to the home.php file but will not echo anything. But as soon as you hit refresh the session is gone.

  • Perl, "closure" using Hash

    - by Mike
    I would like to have a subroutine as a member of a hash which is able to have access to other hash members. For example sub setup { %a = ( txt => "hello world", print_hello => sub { print ${txt}; }) return %a } my %obj = setup(); $obj{print_hello}; Ideally this would output "hello world"

  • Image upload not functioning correctly

    - by PurpleSmurf
    I'm still trying to get to grips with PHP, and I'm trying to make a form that uploads a picture to a database. I don't have permissions for move_uploaded_file so I'm using the copy() as an alternative. Everywhere I've seen experiencing similar problems have all been with move_uploaded_file so I'm rather stuck. Trying to copy the image from the desktop doesn't seem to be working, it's not throwing up any more PHP errors but is displaying the error message for if something goes wrong. The form sends data to two tables in the database but I'm mainly concerned with the upload not working. There's over 200 lines so I'll post a snippet of the upload code, thank you in advance: function getExtension($str) { $i = strrpos($str,"."); if (!$i) { return ""; } $l = strlen($str) - $i; $ext = substr($str,$i+1,$l); return $ext; } //This variable is used as a flag. The value is initialized with 0 (meaning no error found) and it will be changed to 1 if an errro occures. If the error occures the file will not be uploaded. $errors=0; //checks if the form has been submitted if(isset($_POST['submitted'])) { //reads the name of the file the user submitted for uploading $image=$_FILES['image']['name']; //if it is not empty if ($image) { //get the original name of the file from the clients machine $filename = stripslashes($_FILES['image']['name']); //get the extension of the file in a lower case format $extension = getExtension($filename); $extension = strtolower($extension); //if it is unknown extension, class as an error and do not upload the file, otherwise continue if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) { //print error message echo '<h1>Unknown extension!</h1>'; $errors=1; } else { //get the size of the image in bytes //$_FILES['image']['tmp_name'] is the temporary filename of the file in which the uploaded file was stored on the server $size=filesize($_FILES['image']['tmp_name']); //give an unique name, for example the time in unix time format $image_name=time().'.'.$extension; //the new name will be containing the full path where will be stored (images folder) $newname="/home/k0929907/www/uploads/".$image_name; //verify if the image has been uploaded, and print error instead $copied = copy($_FILES['image']['tmp_name'], $newname); if (!$copied) { echo '<h1>Copy unsuccessfull!</h1>'; $errors=1; } } } }

  • What is the difference between printf() and puts() in C?

    - by alex
    First up, I should let you know that I am learning C, so my apologies if this question seems stupid to a more advanced developer. I know you can print with printf() and puts(). I can also see that printf() allows you to embed variables inside and do some stuff like formatting. Is puts() merely a primitive version of printf(). Should it be used for every possible printf() without string interpolation? Thanks

    - by Jon
    I have simple template that's html mostly and then pulls some stuff out of SQL via PHP and I want to include this template in three different spots of another php file. What is the best way to do this? Can I include it and then print the contents?

    I try two use sidewaysfigure from the rotating package in the twosided memoir class. The resulting figures look correct in the pdf that is generated, with the page rotated by 90 degrees. However, when I print the document (on linux, using CUPS), some of the pages with a sidewaysfigure are upside down (rotated by 180 degreeS).
