  1. Im currently creating a site for a University project but struggling with the file directories and image uploading. I've managed to get a profile image visible and working but the aim is to allow users to upload many images, which will be visible on their profile page. The image files appear in the main directory instead of in "images/". Also Although they are recognised in the database they don't appear on the profile page of the user... Also within 'functions.php' this function is used to call the images onto a profile page. What does '$user.jpg' need to be replaced with in order to show all the images uploaded by one specific user? Below are the two PHP files concerned with the image upload process. Firstly 'function.php'. <?php $dbhost = '...'; $dbname = '...'; $dbuser = '...'; $dbpass = '...'; $appname = "..."; $link = mysql_connect($dbhost, $dbuser, $dbpass); mysql_select_db($dbname, $link) or die(mysql_error()); function createTable($name, $query) { if (tableExists($name)) { echo "Table '$name' already exists<br />"; } else { queryMysql("CREATE TABLE $name($query)"); echo "Table '$name' created<br />"; } } function tableExists($name) { $result = queryMysql("SHOW TABLES LIKE '$name'"); return mysql_num_rows($result); } function queryMysql($query) { $result = mysql_query($query) or die(mysql_error()); return $result; } function destroySession() { $_SESSION=array(); if (session_id() != "" || isset($_COOKIE[session_name()])) setcookie(session_name(), '', time()-2592000, '/'); session_destroy(); } function sanitizeString($var) { $var = strip_tags($var); $var = htmlentities($var); $var = stripslashes($var); return mysql_real_escape_string($var); } function log_image_upload($Filename, $Location, $Time) { //add in sanitization code in here for all variables being parsed. mysql_query("INSERT INTO `images` (`filename`, `location`, `time`) VALUES ('$Filename', '$Location', '$Time')"); } function showProfile($user) { if (file_exists("$user.jpg")) echo "<img src='$user.jpg' border='1' align='left' />"; $result = queryMysql("SELECT * FROM rnprofiles WHERE user='$user'"); if (mysql_num_rows($result)) { $row = mysql_fetch_row($result); echo stripslashes($row[1]) . "<br clear=left /><br />"; } } ?> And secondly 'profile.php' is below ?php // rnprofile.php include_once 'rnheader.php'; if (!isset($_SESSION['user'])) die("<br /><br />You need to login to view this page"); $user = $_SESSION['user']; echo "<h3>Edit your Profile</h3>"; ?> </br> <?php if (isset($_POST['text'])) { $text = sanitizeString($_POST['text']); $text = preg_replace('/\s\s+/', ' ', $text); $query = "SELECT * FROM rnprofiles WHERE user='$user'"; if (mysql_num_rows(queryMysql($query))) { queryMysql("UPDATE rnprofiles SET text='$text' where user='$user'"); } else { $query = "INSERT INTO rnprofiles VALUES('$user', '$text')"; queryMysql($query); } } else { $query = "SELECT * FROM rnprofiles WHERE user='$user'"; $result = queryMysql($query); if (mysql_num_rows($result)) { $row = mysql_fetch_row($result); $text = stripslashes($row[1]); } else $text = ""; } $text = stripslashes(preg_replace('/\s\s+/', ' ', $text)); if (isset($_FILES["image"]["name"])) { $FolderName = 'simple/'; // Setting the upload directory $CurrentTime = time(); // Time of upload (UNIX) $Filename = $user."_".$CurrentTime.".jpg"; // Filename of the file $saveto = $Foldername.$Filename; // Will look something like"images/alex_1365249148.jpg" move_uploaded_file($_FILES["image"]["tmp_name"], $saveto); $typeok = TRUE; switch($_FILES["image"]["type"]) { case "image/gif": $src = imagecreatefromgif($saveto); break; case "image/jpeg": // Both regular and progressive jpegs case "image/pjpeg": $src = imagecreatefromjpeg($saveto); break; case "image/png": $src = imagecreatefrompng($saveto); break; default: $typeok = FALSE; break; } if ($typeok) { list($w, $h) = getimagesize($saveto); $max = 150; $tw = $w; $th = $h; if ($w > $h && $max < $w) { $th = $max / $w * $h; $tw = $max; } elseif ($h > $w && $max < $h) { $tw = $max / $h * $w; $th = $max; } elseif ($max < $w) { $tw = $th = $max; } $tmp = imagecreatetruecolor($tw, $th); imagecopyresampled($tmp, $src, 0, 0, 0, 0, $tw, $th, $w, $h); imageconvolution($tmp, array( // Sharpen image array(-1, -1, -1), array(-1, 16, -1), array(-1, -1, -1) ), 8, 0); imagejpeg($tmp, $saveto); log_image_upload($Filename, $saveto, $CurrentTime); // Logging the image upload into MySQL imagedestroy($tmp); imagedestroy($src); } } showProfile($user); echo <<<_END <form method='post' action='rnprofile.php' enctype='multipart/form-data'> Enter or edit your status and/or upload an image:<br /> <textarea name='text' cols='50' rows='4'>$text</textarea><br /> Image: <input type='file' name='image' size='14' maxlength='32' /> <input type='submit' value='Save Profile' /> </pre></form> _END; ?> Any help would be much appreciated! thanks.
  2. There is 2 parts to this post. The first part is this: I'm making a social network with followers on it. I want to people to be able to follow each other, so I have a database and a table of users. I've thought about how it would be possible for someone to follow a lot of people (say millions if they wanted to). My first thought was to create a table and just make 1 column for the username of the person and then add a bunch of columns of the usernames that person is following...but that's inefficient. So I needs ideas and advice on the code. Is there a possible way that when a person follows someone the system checks to see if that person has followed anyone else and if not they it puts their username in the first column and then puts the followee's username in the next column. Then when they follow someone else it look up the followers username name and just adds the next followee's username into the columns after the last followee? That way I don't have to have a set number of people that users can follow. Then there is the "news feed" part. I want to create a "news feed" that displays the posts of all the people the user follows. I have a table of posts that are flagged by the authors username and I WILL have the table of people the user follows. Any ideas on how to make the feed display in order what the peoples posts are that the user follows?
  3. Guys, Recently, we've released our new social network. We would like to hear your opinions about the design and the features. We know that the HTML and CSS is not completely okay, but we're planning on cleaning up the code as soon as possible. This is a very basic version of what we want Scrapll to be in the future, so we would really appreciate it if you guys could give us some tips about what features we should add to Scrapll in order to make it better. The link: http://www.scrapll.com Please try to use as many features as possible to understand the site better and also to test the features in your browsers and displays. Thanks in advance! Cheers, Scrapll team
