Thanks PaulRyan your code worked perfectly! @Pickachu2000 Don't worry the serials are saved to a database and the newly generated ones are checked against the db.

So I wrote this code to generate a 12 character long serial number looking something like this: 123a-34se-sdf3 I am new to php and really bad at using loops. If some one could explain to me some method of repeating the action rather than having to copy and paste. $ser_num = array("1","2","3","4","5","6","7","8","9","0","A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"); $num1 = rand(0,count($ser_num)-1); $numf1 = wordwrap($ser_num[$num1],1,"\n", true); $num2 = rand(0,count($ser_num)-1); $numf2 = wordwrap($ser_num[$num2],1,"\n", true); $num3 = rand(0,count($ser_num)-1); $numf3 = wordwrap($ser_num[$num3],1,"\n", true); $num4 = rand(0,count($ser_num)-1); $numf4 = wordwrap($ser_num[$num4],1,"\n", true); $num5 = rand(0,count($ser_num)-1); $numf5 = wordwrap($ser_num[$num5],1,"\n", true); $num6 = rand(0,count($ser_num)-1); $numf6 = wordwrap($ser_num[$num6],1,"\n", true); $num7 = rand(0,count($ser_num)-1); $numf7 = wordwrap($ser_num[$num7],1,"\n", true); $num8 = rand(0,count($ser_num)-1); $numf8 = wordwrap($ser_num[$num8],1,"\n", true); $num9 = rand(0,count($ser_num)-1); $numf9 = wordwrap($ser_num[$num9],1,"\n", true); $num10 = rand(0,count($ser_num)-1); $numf10 = wordwrap($ser_num[$num10],1,"\n", true); $num11 = rand(0,count($ser_num)-1); $numf11 = wordwrap($ser_num[$num11],1,"\n", true); $num12 = rand(0,count($ser_num)-1); $numf12 = wordwrap($ser_num[$num12],1,"\n", true); $serial = ''.$numf1.''.$numf2.''.$numf3.''.$numf4.'-'.$numf5.''.$numf6.''.$numf7.''.$numf8.'-'.$numf9.''.$numf10.''.$numf11.''.$numf12.'';

Yeah problem solved i modified to the example you gave me to this: http://jsfiddle.net/kKNNE/14/ It's exactly what I need! THANKS!

So I have a series of textboxes and when any of the values are changed I want JS to apply some basic calculations to each and then display the sum. I can do this where it detects the change in one textbox, but I am not sure how to get it to detect a change in any of the textboxes other than copy and pasting the code and changing the id for each. $(document).ready(function()//When the dom is ready { $("#def").keyup(function() { //if theres a change in var def = $("#def").val(); var acc = $("#acc").val(); //Calculate Each Cost var def_cost = def * 5; var acc_cost = acc * 5; //Total Costs var points= Number(acc_cost) + Number(def_cost); //Display Costs in Span $("#pointspreview").html(points); }) });

Thanks scootstah you solution worked perfectly!

Hi I relatively new to PHP and I am having trouble solving this problem: I want to take the number the user has given and then enter it in this equation 100/(2^X). I can do this easily. However I also need to apply the same equation to every number less than the given (If the user enters 4 it must by applied to 3,2,1 as well) I can generate a list of numbers using the range() function: foreach (range(0, $users_number) as $number) { echo $number; } However I can't figure out how to apply the equation to each number. The next step is to get the total sum but given the values of the the others that's pretty easy.

Let me clarify the file is being saved as $serial$title.png. $serial is not a folder. There is no problem with that part of the code. The image gets saved but does no appear in the browser.

So I am trying to generate an image based off of a form filled out by the user. It generates the image which is saved to a folder but the image does not show up in the browser. However when I comment out the header there are no errors! Here is the message I get: "The Image: 'http:// localhost/whatever.php' cannot be displayed because it contains errors. Here is all of the code I included it all because I have no clue what is causing it. <?php require 'connect.inc.php'; require 'core.inc.php'; //Get all info from cardcrafter.php $title = $_REQUEST['title'] ; /* $desc = $_REQUEST['desc'] ; */ $cardart = $_REQUEST['cardart'] ; $atk = $_REQUEST['atk']; $def = $_REQUEST['def']; $acc = $_REQUEST['acc']; $hp = $_REQUEST['hp']; //$quo = ($desc == "") ?

So I have this function which generates a random serial # that is 12 characters long. However I want to insert a dash every four characters like so: XXXX-XXXX-XXXX Any suggestions? <?php $serial1 = get_serial_num(12); //Serial # function function get_serial_num($number_cnt){ $ret_arr = array(); $serial = ""; $ser_num = array("1","2","3","4","5","6","7","8","9","0","A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"); for($i = 0; $i < $number_cnt; $i++){ $rand = rand(0,count($ser_num)-1); $val = wordwrap($ser_num[$rand],1,"\n", true); $serial .= $val; } return $serial; } echo ''.$serial1.''; ?> Warning: I am a bit noobish.

I tried your script and it did not work however I found this plug-in: http://www.mathachew.com/sandbox/jquery-autotab/ So I ended up getting what I needed and some. Thanks for all your help.

Sorry for being a noob but I just tried to figure out how to do that and completely failed. Would you please clarify?

So I have code for three text-boxes in a form: <input type='text' name='serial1' style="width:40px;" maxlength="4"> - <input type='text' name='serial2' style="width:40px;" maxlength="4"> - <input type='text' name='serial3' style="width:40px;" maxlength="4"> What I want to know is if there is anyway to make it so that after the user has typed the max # of characters in the first text box the cursor will automatically move to the next text-box.

YES it worked! Thanks so much. If it's not to much trouble can you tell me why that actually worked.

sorry i'm pretty new at this can you clarify

Ok so I have a form to submits to a .php file that creates an image. This works fine, but I also want the info from the form to be sent to MySQL database. The problem is that something in a script I "required" called core.inc.php is interfering and so no image is output. Here is core.inc.php: <?php ob_start(); session_start(); $current_file = $_SERVER['SCRIPT_NAME']; if(isset($_SERVER['HTTP_REFERER'])&&!empty($_SERVER['HTTP_REFERER'])) { $http_referer = $_SERVER['HTTP_REFERER']; } function loggedin() { if(isset($_SESSION['user_id'])&&!empty($_SESSION['user_id'])) { return true; } else { return false; } } function getuserfield($field) { $query="SELECT `$field` FROM `Users` WHERE `id`='".$_SESSION['user_id']."'"; if($query_run=mysql_query($query)) { if($query_result = mysql_result($query_run, 0, $field)) { return $query_result; } } } ?> Here is the code for the image creating .php file: <?php require 'connect.inc.php'; require 'core.inc.php'; $title = $_REQUEST['title'] ; $user_id = getuserfield('id'); $query = "INSERT INTO `---` VALUES ('".mysql_real_escape_string($title)."','".mysql_real_escape_string($user_id)."')"; $query_run = mysql_query($query); //There is some more code in here obviously, but it's irrelevant header('Content-type: image/png'); imagepng($image_f); imagedestroy($image_f) Can anybody give me some idea of what is conflicting or what I can do to fix it?

Thank you Mahngiel! Problem Solved!!!! :D :D :D

So basically I have two lines that generate an image from png and then preserve the transparency of said png. $bub1 = imagecreatefrompng ("Energy/$energy1b.png"); imageSaveAlpha($bub1, true); This works by itself when generating just this image. But when combined with another image: imagecopymerge($image, $bub1, 680, 40, 0, 0, 50, 50, 100); It fills in the back ground around the image and the transparency is not preserved. Why is this and how can i fix it?

Found a bit of code that solved my problem: // get the quote and word wrap it $quote = wordwrap($quotes[$pos],20); Im unsure what the 20 is actually the value of. Also it seems if you put in one line of text without spaces this method fails to work! HELP!

Can you give me an example or link or something. I am some what of a noob.

So basically I have text which appears on an image. $ability = "$title gets ability"; //Create Ability imagettfbbox(30, 0, $font, $ability); imagettftext($image, 30, 0, 70, 700, $fontcolor, $font, stripslashes($ability)); But the line of text is longer than the width of the area on the image it needs to fit in. How can I change this so it automatically starts a new line once it reaches the end of said area?

So basically do this for each input?

Ok so I wanted to send user input from a form in html send it through Ajax to a Php file, where it would then be messed around with some and output again (The last bit is not important). I have code for sending the info from Ajax to Php. However it is annoyingly long and requires I create a new function for each input. function allrun(){ meaningless = getmeaningless(); if (meaningless != null) { meaningless.open("GET", "Test.php?title=" +document.getElementById('title').value, true); meaningless.send(null); }} How can I collect all the inputs under one function to forward to php?

I also tried the second method and got this message: Warning: imagepng() [function.imagepng]: Unable to open 'img/sdfsa+MJoa.png' for writing: No such file or directory in /Library/WebServer/Documents/temp/test2.php on line 70 Here is the html file: <html> <head> <title>Ajax with jQuery Example</title> <script type="text/JavaScript" src="jquery.js"></script> <script type="text/JavaScript"> $(document).ready(function(){ $("#generate").click(function() { loadImage(); }); function loadImage(){ var inputString = $("#inputString").val(); var inputFont = $("#inputFont option:selected").val(); $("#image p").load("test2.php?text=" + inputString + "&font=" + inputFont) } }); </script> <style type="text/css"> #wrapper { margin-top: 30px; height: 50px; width: 600px; border: 1px solid black; text-align: center; } #image { padding-bottom: 80px; border-style: none; height: 100px; width: 600px; text-align: center; } </style> </head> <body> <center><div id="image"><p> </p></div> <div id="wrapper"> Engraved Text:<input size="30" id="inputString" type="text" /> Font:<select id="inputFont"> <option value="balmo">Balmoral</option> <option value="clar">Clarendon</option> <option value="curlz">Curlz</option> <option value="english">Old English</option> <option value="freehand">Freehand</option> <option value="greek">Greek</option> <option value="interlock">Interlocking Monogram</option> <option value="MJoa">Times</option> <!-- <option value="3">Cool Engraving</option> <option value="3">Cool Engraving</option> <option value="3">Cool Engraving</option> <option value="3">Cool Engraving</option> <option value="3">Cool Engraving</option> --> </select> <input type="submit" id="generate" value="Generate!"> </div> </center> </body> </html> Here is the php: <?php // VARIABLES ############################################################################ // The text to draw $text = $_GET['text']; //$text = 'poopie'; // Font File, don't need a slash if file is in same dir as php file $font = $_GET['font']; //$font = '1'; //size in PTS $size = 78; //Angle $angle = 0; //Width of Canvas $width = 500; //Height of Canvas $height = 200; //Text Bounding Box Dimensions $tb = imagettfbbox($size, $angle, $font, $text); /* Output of imagettfbbox is an array as follows: Array ( [0] => 0 // lower left X coordinate [1] => -1 // lower left Y coordinate [2] => 198 // lower right X coordinate [3] => -1 // lower right Y coordinate [4] => 198 // upper right X coordinate [5] => -20 // upper right Y coordinate [6] => 0 // upper left X coordinate [7] => -20 // upper left Y coordinate ) */ // Centering Function ##################################################################### // X Position Calculated by subtracting width of Text Bounding Box from total canvas width $posx = ceil(($width - $tb[2]) / 2); // Y Position Calculated by subtracting height of Text Bounding Box from total canvas height $posy = ceil(($height - $tb[5]) / 2); // Creating Image File $im = imagecreatetruecolor($width, $height); // State Colors available to Image File $white = imagecolorallocate($im, 255, 255, 255); $grey = imagecolorallocate($im, 128, 128, 128); $black = imagecolorallocate($im, 0, 0, 0); imagefilledrectangle($im, 0, $angle, $width, $height, $white); // Add the text imagettftext($im, $size, $angle, $posx, $posy, $black, $font, $text); // Usage of imagettftext() // array imagettftext ( resource $image , float $size , float $angle , int $x , int $y , int $color , string $fontfile , string $text ) // $file= "$text+$font.png"; imagepng($im, "img/$file"); imagedestroy($im); $imgloc= "img/$file"; echo "<img src=$imgloc>"; ?> I changed one of the fonts to use my font and I installed jquery. What is wrong here???
