Have you tried <?php mail('you@domain.com', 'test', 'test'); ?> If it doesn't work it's a problem with mail, not your script Edit: Also, you don't actually connect to the database. <?php $con = mysql_connect($db_server, $db_username, $db_password); mysql_select_db($db_name, $con); ?>

validating that a username doesnt already exist
LooieENG replied to Lodius2000's topic in PHP Coding Help
$result = mysql_query("SELECT username FROM users WHERE username = '$_POST[username]'"); if ( mysql_num_rows($result) > 0 ) { echo 'Username exists'; } else { // stuff } (Used $_POST['username'] as an example) -
echo "<a href=\"edit_info.php?user={$row['user']}\">EDIT!</a>"; And then on the next page $user = $_GET['user'];

Something like this? I list the blog posts, with a hyperlink for admin.php?do=edit&id=id (use GET) then I get the blog content from the table with that id, and set a variable. Then, in the html bit, if the variable is set, it echos a textarea with the blog content in it, and when the content is edited, the data is submitted with POST and changed
-
Don't know if this has anything to do with it, but you check if $rows2 is 1, but $rows2 is never defined

Thanks. Also, just quickly, is there a significant difference between TEXT and BLOB, and is it better to use VARCHAR? I think I read something like text/blob will always be the same size, whereas varchar is as big as the data it contains plus one byte? Is this right? And is this good for a blog post table? id > tinyint title > tinytext content > text user > varchar(32) time > int Thanks.

What column type should I have to store a timestamp (like 142567442)? If I choose timestamp, it makes it YYYY-MM-DD HH-MM-SS. Just bigint?
-
is the folder "images" CHMODed to 777?
-
Should that not be <?php $query = "INSERT INTO active_users (nowonline) VALUES ('$page')"; $sql = "SELECT (nowonline) FROM active_users"; $verify = mysql_query($query) or die(mysql_error()); $verified=mysql_query($sql)or die(mysql_error()); if($verify) { //dostuff }else{ //error } if($verified) { //dostuff }else{ //error } ?>

Try the nl2br() function
-
Make a folder called styles with style1.css, style2.css, etc. Then, say the page is index.php, do index.php?style=(number of style) And before the HTML tags <?php if ( isset($_COOKIE['style']) ) { $s = 'styles/style' . $_COOKIE['style'] . '.css'; } elseif ( isset($_GET['style'] && ctype_digit($_GET['style']) ) { $s = 'styles/style' . $_GET['style'] . '.css'; setcookie('style', $s, time()+(99999*99999), '/'); } else { // Default style $s = 'styles/style1.css'; } ?> And in the <head> tags of the HTML <link rel="stylesheet" type="text/css" href="<?php echo $s?>" /> Try that, it SHOULD work. Make sure the page ends in .php, not .html You can also probably do it with JavaScript, but I don't really know any, so you'll have to wait for someone who does post

Place a footer div at the bottom, and use #footer { clear: both; } Should fix it
-
For the div on the left of where the ad should be, use margin: 0 120px 0 0; Looks like you've worked it out from your link though
-
Oh, I once had an annoying white border at the top of my page, and it turned out I somehow managed to place a <br /> tag in the <head> section :-\ Have you checked your stylesheet for a{} and .message_rows_subject{}?
-
mysql_query("INSERT INTO active_users (nowonline) VALUES '$SERVER[php_SELF]'");
-
Little white border where, at the top of the page?
-
Add a column to "posts" or whatever called last_post, then when someone posts, add a timestamp to it. Then use something like $result = mysql_query("SELECT * FROM posts ORDER BY last_post DESC"); I Think that should work
-
Woops, forgot to remove those when I edited
-
Can't modify my last post, but it's working now.

<?php //Database Settings $host = 'localhost'); $dbuser = '******'); $pass = '******'); $db = '******'); //MySQL Connection $conn = mysql_connect($host, $dbuser, $pass); if (!conn) { // the connection failed so quit the script die('Could not connect !<br />Please contact the site administrator.'); } $db = mysql_select_db($db); if (!db) { // cannot connect to the database so quit the script die('Could not connect to database <br /> Please contact the site administrator.'); } ?>

The "function", before the actual function means it's setting a function. the $dirname variable relates to the function for example function myFunction($var1, $var2) { echo $var1 . $var2; } The above code means, that when you call the function by typing $var1 = 'hello '; $var2 = 'world!'; myFunction($var1, $var2) It takes the data from the variables $var1 and $var2 are, and uses it in the function. So if you take the above function, but instead of $var1 and $var2, you use 'hello ' and 'world!' like this myFunction('hello ', 'world!') The function takes the values and uses them, so it would echo 'hello world!' So if you do $hi = 'hi. '; $hello = 'hello.'; myFunction($hi, $hello) The function is actually myFunction($hi, $hello) { echo $hi . $hello; } So you set the function first function NameOfFunction($varSomething) { echo $varSomething; } Then you set the variables $hi = 'hi'; Then you call the function, replacing $varSomething with the variable you want the function to echo NameOfFunction($hi) This will echo the word 'hi' because you used $hi, so the function is NameOfFunction($hi) { // Prints the variable used when calling the function echo $hi; } Hope that helps explain it

<?php function printNews($news) { if ( mysql_num_rows($news) < 1 ) { echo "<h1>No news!</h1>"; } else { echo ' <table><tr> <td><h2><u>' . $news['title'] . '</u></h2></td> </tr><tr> <td>' . $news['news'] . '</td> </tr></table><br />'; } } mysql_connect("***", "***", "***") or die(mysql_error()); mysql_select_db("***") or die(mysql_error()); $query1 = "SELECT * FROM stickynews"; $query2 = "SELECT * FROM news"; $result1 = mysql_query($query1) or die(mysql_error()); $result2 = mysql_query($query2) or die(mysql_error()); while($row1 = mysql_fetch_array($result1)) printNews($row1); while($row2 = mysql_fetch_array($result2)) printNews($row2); ?> Like this?

I see, and using else works, but every time I enter something, it says username not found, but I checked the database and the name does exist. <?php // Starts session session_start(); // Checks if user is already logged in if ( $_SESSION['username'] ) { // User is already logged in, so redirecting to the Admin CP header('location: admin.php'); exit; } // Checks if form has been submitted if ( $_POST['login'] ) { // Checks if username contains alphanumeric characters only if ( !ctype_alnum($_POST['username']) ) { // Sets error and exits $ue = '(Alphanumeric characters only.)'; } else { // Sets variables $username = $_POST['username']; $password = md5('salt' . $_POST['password']); // Opens database connection and selects database $con = mysql_connect('localhost', 'xxxxx, 'xxxxx'); mysql_select_db('xxxxx_blog', $con); // Gets data for username from database $result = mysql_query("SELECT password FROM users WHERE username = '$username'"); // Checks if user exists if ( mysql_num_rows($result) < 1 ) { // Sets error $ue = '(Username not found.)'; } else { // Gets rows from database query $row = mysql_fetch_array($result); // Checks if password matches if ( $password != $row['password'] ) { // Sets error $pe = '(The password you entered is incorrect.)'; } else { // Sets session data and redirects to Admin CP $_SESSION['username'] = $username; header('location: admin.php'); // Exits exit; } } } } ?> <!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=utf-8" /> <title>Login</title> </head> <body> <form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post" name="login"> Username: <input name="username" type="text" size="30" /> <?php echo $ue ?><br /> Password: <input name="username" type="password" size="30" /> <?php echo $pe ?><br /> <input name="login" type="submit" value="Log in" /> </form> </body> </html> Thanks

Place the function bit before you use it
-
if ( mysql_num_rows($queries) < 1 ) { // stuff } Is that what you mean?
