I'm using objects as associative arrays in Javascript. var Cake = new Object(); Cake['ice cream'] = 'yummy'; Cake['chocolate'] = 'mmm'; Cake['none'] = 'aww...'; Do objects have a method or property that would tell me how many elements the pseudo-associative array Cake has? Please don't tell me the only way is to loop through each element and count them. Thanks.

Yea, it seemed to be the color palette. I just stuck with png. Thanks guys.

Can you explain what that has to do with text color?

Honestly, why do you think exporting as a gif would change the color of the text? It doesn't work for me. And you also keep the header as image/png while exporting imagegif.

<? $img = imagecreatefromgif('resources/sig_bg.gif'); $background = imagecolorallocate($img, 0, 0, 0); $white = imagecolorallocate($img, 255, 255, 255); $bbox = imagettfbbox(16, 0, 'resources/CALIBRIB.TTF', 'wrong'); imagettftext($img, 16, 0, 455 - $bbox[2], 70, $white, 'resources/CALIBRIB.TTF', 'wrong'); header('Content-type: image/png'); imagepng($img); imagedestroy($img); ?> As you can see, I open an image stored locally on my server. It then uses imagettftext to write white text on the image. However, this is where it screws up. The text it writes is black, not white. I'm not entirely sure what I am doing wrong. Any ideas? I tried $img = imagecreate(500, 100); and it writes the text correctly, with the correct color. It seems like there is something incompatible when I use imagecreatefromgif and imagettftext.

$_GET['user'] == NULL ? $GET['user'] = 'roflwaffle' : str_replace(' ', '_', strtolower($GET['user'])); str_replace does not seem to recognize spaces. It does not swap them for underscores, as it should. What am I doing wrong?

if (!empty($_POST['query'])) { $dict = file_get_contents('sowpods.txt'); // Get contents of dictionary in $dict. if (strpos($dict, "\n" . strtoupper(htmlentities($_POST['query'])) . "\n") === false) { echo '<div id="no"><p>No</p></div>'; } else { echo '<div id="yes"><p>Yes</p></div>'; } } The SOWPODS dictionary is arranged like: AARDVARK AARDVARKS AARDWOLF AARDWOLVES A \n before each word, and a \n after. How would you optimize this code snippet?

<?php error_reporting(E_ALL); switch ($_GET['purpose']) { case 'news': $result = mysql_query('SELECT `fulltext` FROM `news` WHERE `newsID` = ' . htmlentities($_GET['argument'] . ' AND `deleted` = 0', ENT_QUOTES)); $fulltext = mysql_fetch_array($result); /* Line 8. */ echo 'document.getElementById("text_' . htmlentities($_GET['argument']) . '").innerHTML = "' . str_replace(array("\n", "\r", "\r\n"), '', $fulltext[0]['fulltext']) . '";'; break; default: } ?> That's ajax.php. When I call .../assets/ajax/?purpose=news&argument=2, it gives me a: Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in .../assets/ajax/index.php5 on line 8

I stuck the tickmarks in later, but I didn't know about the fulltext part. Thanks.

INSERT INTO `news` (origID, title, summary, fulltext, timestamp, timestamp2, author, ip) VALUES (3, 'title of it', 'summary of it', 'full text of it', 1194919992, 1194919992, 'loladmin', '68.193.xx.xx') Fatal Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'fulltext, timestamp, timestamp2, author, ip) VALUES (3, 'title of it', 'summary ' at line 1 newsID - smallint(6) - auto_increment, primary key origID - smallint(6) title - varchar(50) summary - text fulltext - mediumtext timestamp - int(10) timestamp2 - int(10) author - varchar(20) ip - varchar(16) What am I doing wrong? I hate these cryptic MySQL errors.

Is there any way for me to send a POST variable, such as a password, to a page such as '/admincenter.php?a'?

Try changing: print "<track><location>".$flv."</location></track>"; to echo '<track><location>' . str_replace("\n", '', $flv) . '</location></track>'; Also, in your second xml output, there is no open trackList. Is this intentional?

Did you try putting username and new in quotes?

Shouldn't username and new be in quotes?

foreach ($_REQUEST as $key => $value) { $_REQUEST[$key] = htmlentities($value); } This is what I have in the beginning of every page that has GET/POST variables pass through.

htmlentities() mebbe?

Thanks. This works: <?php class mysql { protected $mysqlconn; function __construct($db_hostname = '******', $db_username = '******', $db_password = '******', $db_name = '*****') { $this -> mysqlconn = @mysql_connect($db_hostname, $db_username, $db_password) or die('Could not connect: ' . mysql_error()); mysql_select_db($db_name, $this -> mysqlconn); } function query($querystr) { } function __destruct() { @mysql_close($this -> mysqlconn); } } ?> edit by redbullmarky: be careful with leaving the login info in your code

I know this is a tad offtopic, but did you purposefully spell it 'bazar' as opposed to 'bazaar'? It looks really weird.

This sounds like the work of AJAX. Basically, when you click the next button, you want javascript to create an external javascript include in the body of the page. This reference includes a .php file, to which you can pass various parameters through get variables. This .php file gets something from your database, and then outputs javascript that can remove the text of the previous joke and add the text of the next joke. If you want more specifics, just ask me.

I'm just starting off with OOP, and to be honest, no tutorials provide some applicable examples, so I decided to learn through trial and error. I'm writing a basic MySQL class, and I'm running into this error. Warning: mysql_connect() [function.mysql-connect]: Can't connect to local MySQL server through socket '/tmp/mysqld.sock' (2) in /homepages/.../classes/mysql.php5 on line 10 index.php5: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> <?php error_reporting(E_ALL); require_once('classes/mysql.php5'); $result = new mysql(); unset($result); ?> </body> </html> mysql.php5: <?php class mysql { protected $hostname = 'xxxxxx.perfora.net'; protected $username = 'dboxxxxxxxx'; protected $password = 'xxxxxxxxx'; protected $dbname = 'dbxxxxxxx'; protected $mysqlconn; protected $querystr; function __construct($hostname = NULL, $username = NULL, $password = NULL, $dbname = NULL) { $mysqlconn = mysql_connect($hostname, $username, $password) or die('Could not connect: ' . mysql_error()); mysql_select_db($dbname, $mysqlconn); } function query($querystr) { } function __destruct() { mysql_close($mysqlconn); } } ?> Any thoughts?

Wouldn't SMF be a testament to MySQL's scalability?

The function takes the event that is passed into it and then gets the keycode from that. Is there any way to modify the JS to make it work?

It seems I cannot access 'event' from the head. event is not defined... Line 25 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <script language="javascript" type="text/javascript"> function storeLetters(ev) { if (window.event) { keynum = ev.keyCode; } else if (ev.which) { keynum = ev.which; } keychar = String.fromCharCode(keynum); if (sofar == undefined) { sofar = keychar; } else { sofar += keychar; } if (sofar.length > 10) { alert(sofar); } } var sofar; onload = function(){ document.getElementById('iframeID').onkeydown = storeLetters(event); ****Line 25**** } </script> </head> <body> <iframe src="test.php5" id="iframeID"></iframe> <textarea></textarea> </body> </html>

Yes you could, though it would be a bitch to code without the source to your site.

HTML File: <html> <head> <script type="text/javascript"> function deleteFileAjax(filename) { scriptitem = document.createElement('script'); scriptitem.type = 'text/javascript'; scriptitem.src = 'ajax.php?filename=' + filename; scriptitem.id = 'ajax'; document.body.appendChild(scriptitem); setTimeout('document.body.removeChild(document.getElementById("ajax"))', 500); } </script> </head> <body> <a href="javascript:deleteFileAjax('log.txt');">Delete</a> </body> </html> Ajax.php <?php if (isset($_GET['filename'])) { if (unlink(htmlentities($_GET['filename']))) { echo "alert('Great success!');"; } } ?>
