angelfish723 Posted August 30, 2010 Share Posted August 30, 2010 I'm am somewhat new to PHP and am trying to set up a website for my cousin's wedding. Her idea is to have the guests sign in with a user/pass that she provides, and once they sign in, they will be taken to a page that has their name on it (i.e. "Mr. and Mrs. So and So, you are invited...). I have come to the conclusion that I will need to make an image for each guest's name (she wants to use a font for their names that nobody will have on their computer) so what I need to know is: How do I link each user name to their own personalized webpage, where the image of their name on the next page will change based on what username is entered? The php code I have right now is this (i'm sorry it's so long, I just don't want to leave anything out that might be important): $LOGIN_INFORMATION = array( 'steve' => 'password', 'rick' => 'password', 'tom'=> 'password' ); // request login? true - show login and password boxes, false - password box only define('USE_USERNAME', true); // User will be redirected to this page after logout define('LOGOUT_URL', 'http://www.example.com/'); // time out after NN minutes of inactivity. Set to 0 to not timeout define('TIMEOUT_MINUTES', 0); // This parameter is only useful when TIMEOUT_MINUTES is not zero // true - timeout time from last activity, false - timeout time from login define('TIMEOUT_CHECK_ACTIVITY', true); ################################################################## # SETTINGS END ################################################################## /////////////////////////////////////////////////////// // do not change code below /////////////////////////////////////////////////////// // show usage example if(isset($_GET['help'])) { die('Include following code into every page you would like to protect, at the very beginning (first line):<br><?php include("' . str_replace('\\','\\\\',__FILE__) . '"); ?>'); } // timeout in seconds $timeout = (TIMEOUT_MINUTES == 0 ? 0 : time() + TIMEOUT_MINUTES * 60); // logout? if(isset($_GET['logout'])) { setcookie("verify", '', $timeout, '/'); // clear password; header('Location: ' . LOGOUT_URL); exit(); } if(!function_exists('showLoginPasswordProtect')) { // show login form function showLoginPasswordProtect($error_msg) { ?> <html> <head> <title>Please enter password to access this page</title> <META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE"> <META HTTP-EQUIV="PRAGMA" CONTENT="NO-CACHE"> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <style type="text/css"> body,td,th { font-family: Verdana, Geneva, sans-serif; font-size: 10px; color: #666; } body { background-color: #FFFFFB; } </style> </head> <body> <div align="center"> <style> input { border: 1px solid black; } </style> <div style="width:600px; margin-left:auto; margin-right:auto; text-align:center"> <form method="post"> <h4>Please sign in using the information provided on the invitation</h4> <font color="red"><?php echo $error_msg; ?></font><br /> <?php if (USE_USERNAME) echo 'Login:<br /><input type="input" name="access_login" /><br />Password:<br />'; ?> <input type="password" name="access_password" /><p></p><input type="submit" name="Submit" value="Submit" /> </form> <br /> <a style="font-size:9px; color: #B0B0B0; font-family: Verdana, Arial;" href="http://www.zubrag.com/scripts/password-protect.php" title="Download Password Protector">Powered by Password Protect</a> </div> </body> </html> <?php // stop at this point die(); } } // user provided password if (isset($_POST['access_password'])) { $login = isset($_POST['access_login']) ? $_POST['access_login'] : ''; $pass = $_POST['access_password']; if (!USE_USERNAME && !in_array($pass, $LOGIN_INFORMATION) || (USE_USERNAME && ( !array_key_exists($login, $LOGIN_INFORMATION) || $LOGIN_INFORMATION[$login] != $pass ) ) ) { showLoginPasswordProtect("Incorrect password."); } else { // set cookie if password was validated setcookie("verify", md5($login.'%'.$pass), $timeout, '/'); // Some programs (like Form1 Bilder) check $_POST array to see if parameters passed // So need to clear password protector variables unset($_POST['access_login']); unset($_POST['access_password']); unset($_POST['Submit']); } } else { // check if password cookie is set if (!isset($_COOKIE['verify'])) { showLoginPasswordProtect(""); } // check if cookie is good $found = false; foreach($LOGIN_INFORMATION as $key=>$val) { $lp = (USE_USERNAME ? $key : '') .'%'.$val; if ($_COOKIE['verify'] == md5($lp)) { $found = true; // prolong timeout if (TIMEOUT_CHECK_ACTIVITY) { setcookie("verify", md5($lp), $timeout, '/'); } break; } } if (!$found) { showLoginPasswordProtect(""); } } ?> ************************************************************** THANK YOU SO MUCH for any help!!

AbraCadaver Posted August 30, 2010 Share Posted August 30, 2010 That's a lot to go through so I'll just give you the methodology. I see you're using a cookie, but if you used sessions it would store a cookie and allow you to persist variables across pages. So start a session and once they have loggedin, store their username in a session var. Then you can retrieve this on any page and use it to determine the images etc. $_SESSION['username'] = $_POST['access_login']; // then on other pages <img src="images/<?php echo $_SESSION['username']; ?>.png"> Quote Link to comment Share on other sites More sharing options...
ignace Posted August 30, 2010 Share Posted August 30, 2010 I'm am somewhat new to PHP and am trying to set up a website for my cousin's wedding. When became wedding's so complicated? Quote Link to comment Share on other sites More sharing options...
angelfish723 Posted August 30, 2010 Author Share Posted August 30, 2010 Shawn, I think I'm close to understanding what you're telling me, but how do I use sessions instead of cookies? Is it safe to take all the cookie code out of that and replace it with the code you gave me or is there a lot more to it than that? (I'm probably a lot newer to PHP than I should be, but there's a first for everything!) I really do appreciate your help!! Sam Quote Link to comment Share on other sites More sharing options...
The Eagle Posted August 30, 2010 Share Posted August 30, 2010 Wouldn't if work with your situation even if you still used cookies, if ($username == "tim") { echo "<img src=img/tim.jpg>"; } elseif ($username == "bob") { echo "<img src=img/bob.jpg>"; } elseif ($username == "grace") { echo "<img src=img/bob.jpg>"; } ?> Supercode! EDIT: Totally wasn't thinking when I wrote that... made a few silly mistakes. Quote Link to comment Share on other sites More sharing options...
angelfish723 Posted August 30, 2010 Author Share Posted August 30, 2010 The Eagle, I will try that out tonight, thank you!! Quote Link to comment Share on other sites More sharing options...
The Eagle Posted August 30, 2010 Share Posted August 30, 2010 The Eagle, I will try that out tonight, thank you!! Yep, fixed it a bit. Also, if the list is huge, like I'd assume a wedding list would be, having 30 elseif statments isn't exactly poetry. If that's your case, you can go to AbraCadaver's solution with PHP cookies. A short example, if there is a password to gain access, you may need a MySQL database. Here's how you can use a cookie, $_POST['username']; $username = $username; setcookie("Cookie", $username); setcookie("Cookie", $username, time()+3600); // one hour expiration EDIT: Wow.. I can't read today. So he said use SESSIONS, sorry. <?php session_start(); $_SESSION['username'] = $username; $_SESSION['time'] = time(); ?> Then you can look toward his solution, <img src="images/<?php echo $_SESSION['username']; ?>.png"> Quote Link to comment Share on other sites More sharing options...
jcbones Posted August 31, 2010 Share Posted August 31, 2010 I would go in a totally different way, and let PHP generate the images, all you have to do is pass the name to the PHP image file. The steps are. 1. Choose your font file. You can use any True Type Font, or .ttf file, some located Here 2. Make you a PHP file named image.php, it should look like: image.php <?php // Set the content-type header('Content-type: image/png'); $text = (isset($_GET['text'])) ? preg_replace('~[^a-zA-Z\.\s]~','',$_GET['text']) : exit(); $font = 'A.C.M.E._Explosive_Bold.ttf'; //location of your true type font. File name should NOT have any spaces. // Create the image $im = imagecreatetruecolor(400, 30); // Create some colors $white = imagecolorallocate($im, 255, 255, 255); $grey = imagecolorallocate($im, 150, 150, 150); $black = imagecolorallocate($im, 0, 0, 0); imagefilledrectangle($im, 0, 0, 399, 29, $white); // Add some shadow to the text imagettftext($im, 20, 0, 31, 30, $grey, $font, $text); // Add the text imagettftext($im, 20, 0, 30, 29, $black, $font, $text); // Using imagepng() results in clearer text compared with imagejpeg() imagepng($im); imagedestroy($im); ?> 3. After login, set their name to a $_SESSION variable. //Login is complete. $_SESSION['user'] = $userId; 4. Pass the user id to the image file through an html image tag. <img src="image.php?text=<?php echo $_SESSION['user']; ?>" alt="none" /> Or for testing <img src="image.php?text=John%20Smith" alt="none" /> Quote Link to comment Share on other sites More sharing options...
fortnox007 Posted August 31, 2010 Share Posted August 31, 2010 I'm am somewhat new to PHP and am trying to set up a website for my cousin's wedding. When became wedding's so complicated? Since women decided it was fun I hope you do know there are ways to include a font in a website, instead of making a million images? Just google for @font css, might not be extremly legal, but it's just another way of doing it. - edit: I didnt saw jc bones post Quote Link to comment Share on other sites More sharing options...
litebearer Posted August 31, 2010 Share Posted August 31, 2010 no image, no font on users computer, easy to use... http://www.cre8ivecommando.com/the-best-way-to-embed-a-font-in-your-website-2025/ Quote Link to comment Share on other sites More sharing options...

I understand the code you gave me, but I can't get it to work and it's driving me insane! I pasted that into my password php document, right under the Login array info (and I'm not getting any syntax errors, which makes me think it's okay?) ... then in the file for the page that I want the login to take them to, I pasted this: <?php echo $username; ?>, you are invited... But when I test it out, nothing shows up except the ", you are invited..." I also tried the embedded fonts method: if ($username == "tim") { echo "Mr. and Mrs. Tim", you are invited... } and ",you are invited" shows up in my font, but it's blank before that, just like when I try to make an image show up. Are you able to tell me what I'm doing wrong?? Thank you!! Quote Link to comment Share on other sites More sharing options...

I'd love to go with the easiest route... I just have no idea where to put this SESSION code into what I already have. What do I replace it with, or is it additional to what I already have?
