    Counting an Object's Children

    in Javascript Help

    Posted

    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.  :)

    [SOLVED] imagettftext() does not use the color I specify

    in PHP Coding Help

    Posted 

    <?
$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.

    Optimizing this snippet.

    in PHP Coding Help

    Posted 

    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?

    [SOLVED] mysql_fetch_array() problem

    in MySQL Help

    Posted 

    <?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

    [SOLVED] Fatal Error: You have an error in your SQL syntax

    in MySQL Help

    Posted

    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.

    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?

    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.

function query($querystr) {

    Any thoughts?

    you dont need to pass in event to the function

     

    in the onload function, change it to = storeLetters;

     

    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?

    deleting a file onclick

    in Javascript Help

    Awesome!  Thank you, sneamia.  It worked.  Now one more question for you.  Instead of popping up an alert to say "file deleted."  Can I have it just pop text on the page that the file was deleted using ajax like how gmail or facebook works.

    Thanks

    Mike

     

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