Hey everyone,

 

I have a script that validates the users that use my website with a box displaying 9 numbers.  They have to click the number that is displayed at the top with the "Click 9" for example, and they have to click 9 in the list.

 

The problem I have is that the script was given to me by a friend, and I can't work out how to make the boxes/text bigger.  I have fiddled before and the results have been fruitless..  If someone could post back to me with the areas I need to change, and what I have to change, I would be extremely grateful.

 

the first page is below:

 

<?php


//////////////////////////////////////////////////////////////
/////////////////////////////////////////////

if($_SESSION['validated'] == 1) { //changed the = with ==
echo "<meta http-equiv=\"refresh\" content=\"0;URL=$destination.php\">";
exit();
}

//buffer
ob_start('ob_gzhandler'); 





// if submit
if ($_POST[x]){ 
// posted 
$x = $_POST[x];	 
$y = $_POST[y];	
// decode and round number 
$aa = round(base64_decode($_SESSION['afloat']));
// x&y coords	
$xc[1] = ($x >= 1) && ($x <= 17); 
$xc[2] = ($x >= 18) && ($x <= 36);
$xc[3] = ($x >= 37) && ($x <= 53); 
if (($y >= 18) && ($y <= 35)){$ab = $aa;}
elseif (($y >= 36) && ($y <= 51)){$ab = $aa - 3;}
else {$ab = $aa - 6;}
//demo ERROR message below
$mess = "ERROR"; 
//
if ($xc[$ab]){
// submit your form 
//demo SUCCESS message below
$mess = "SUCCESS";
}
//demo alert message below



if($mess=='SUCCESS'){


	echo "<meta http-equiv=\"refresh\" content=\"0;URL=$destination.php\">";
	exit();
}

if($mess=='ERROR'){


	echo "<meta http-equiv=\"refresh\" content=\"0;URL=validate_$destination.php?msg=error\">";


}

ob_end_flush(); 
exit; 
} 
$afloat = base64_encode(" " .  $num1 = rand(1, . "." .  $num2 = rand(100,999) . "  ");
// rectangle y coord 
$aler = "> 18";  
// create random image
$_SESSION[igif] = "image_grid.php?a=" . $afloat . "";
$_SESSION['afloat'] = $afloat; 
?>
<html>
<head>
<style type="text/css"> 
/* click image */
.cd { 
width: 54px;
height: 69px; 
background-image: url(<?=$_SESSION[igif];?>);
background-repeat: no-repeat;
position: relative; 
left:<?=rand(-100,100);?>px;
bottom:<?=rand(25,25);?>px;
z-index: 2;
} 
</style>
<script language="JavaScript"> 
// submit form func 
function submitform() { 
// if box coord submit else rectangle coord alert 
// Do not edit javascript below this line. you can edit the alert message 
if (document.xycoords.y.value <?=$aler;?>) { 
document.xycoords.submit();
} else { 
alert("Click number in square identicale to number in rectangle to submit.");
} 
}
// image x&y value
function xycoord(event) { 
imagex = event.offsetX?(event.offsetX):event.pageX-document.getElementById("coord").offsetLeft;
document.xycoords.x.value = imagex;
imagey = event.offsetY?(event.offsetY):event.pageY-document.getElementById("coord").offsetTop;
document.xycoords.y.value = imagey;
} 
</script>	

<div align="center"><form name="xycoords" action="<?=$_SERVER['PHP_SELF']; ?>" method="post">
<table summary="" border="0">
                    	<tr> <!-- include hidden form input: x >>>>>--><input type="hidden" name="x" /><!-- include hidden form input: y >>>>>--><input type="hidden" name="y" />
                    		<td><span class="h1">Verify yourself</span></td>
                    	</tr>
                    </table>  </form><!-- This line >>>> <div id="coord" onclick="submitform(xycoord(event))" class="cd"></div> >>> Must be outside of form tags <form></form> to work in FF, NS and Opera >>>> -->
	<p><br></p><div id="coord" class="cd" onclick="submitform(xycoord(event))"></div>  
</div>

<div align="center">

<?php 
if($_GET['msg']=="error"){
$msg="<span class='error'>Incorrect Choice.  Please click the right number</span>";

echo "$msg"; 
}
?>

</div>

</body>
</html>
<? ob_end_flush();?>

 

 

 

The second script which is included in this file is:

 

<?php 

//buffer
ob_start('ob_gzhandler');
session_start();
//DEC 67 
//get a, decode and round
// 
$a = $_GET['a'];
if ($a == $_SESSION['afloat']){
$aa = round(base64_decode($a)) - 1; 
$im = imagecreatetruecolor (54, 69);
//DEC 79 
//random numbers
// 
$myn = array(1, 2, 3, 4, 5, 6, 7, 8, 9);
$rn = array_rand($myn, 9);
$string1 = "" . $myn[$rn[0]] . " " . $myn[$rn[1]] . " " . $myn[$rn[2]] . "";
$string2 = "" . $myn[$rn[3]] . " " . $myn[$rn[4]] . " " . $myn[$rn[5]] . "";
$string3 = "" . $myn[$rn[6]] . " " . $myn[$rn[7]] . " " . $myn[$rn[8]] . "";   
$mynum = "" . $string1 . " " . $string2 . " " . $string3 . "";
//DEC 68 DEC 69 DEC 66  DEC 89  DEC 82
//string, random click number and line coord
$na = 17;
$nb = 54;
$nc = 0; 
$nd = 54;
$ab = explode(" ", $mynum);
$mystring = "Click $ab[$aa]";
//random image color
//
$change = rand(1,9);
$lime = imagecolorallocate($im,0,255,0);
$yellow = imagecolorallocate($im,255,255,0);
$white = imagecolorallocate($im,255,255,255);
$lgray = imagecolorallocate($im,206,206,206); 
$gray = imagecolorallocate($im,115,115,115); 
$black = imagecolorallocate($im,0,0,0);
$green = imagecolorallocate($im,1,107,0);
$grc = " $lime $yellow $white $lgray $yellow $white $gray $black $green";
$rc = explode(" ", $grc);
$bgc = $rc[$change]; 
//DEC 72 
//line & number colors
//
$bc = imagecolorallocate ($im, 0, 0, 0); 
$rd = imagecolorallocate ($im, 255, 0, 0); 
$wh = imagecolorallocate ($im, 255, 255, 255);
//DEC 73 
//if color = this change line & number color 
//
if (($change > 3) && ($change < 7)) { $bc = $rd;} 
elseif ($change > 6) { $bc = $wh;}
//DEC 67 
//fill image color
// 
imagefilledrectangle ($im, 0, 0, 54, 69, $bgc);
imagerectangle ($im, 0, 0, 53, 68, $bc); 
//DEC 75 
//vertical lines 
//
for($i=$na;$i<=$nb;$i+=19)
imageline($im,$i,17,$i,(69)-2,$bc);
// Horizontal Lines
for($i=$na;$i<=$nb;$i+=17)
imageline($im,2,$i,(54)-2,$i,$bc);
//DEC 69 
//image string
//    
imagestring ( $im, 5, 5, 18,$string1, $bc);
imagestring ( $im, 5, 5, 35,$string2, $bc);
imagestring ( $im, 5, 5, 52,$string3, $bc);  
imagestring ($im, 3, 2, 3, "$mystring", $bc); 
//DEC 89 
//header content 
//
header("Content-Type: image/gif"); 
//DEC 48 
//send image
//
imagegif($im); 
//DEC 55 
//destroy image 
//
imagedestroy($im); 
}
//flush


ob_end_flush();
?>

 

Thank you in advance everyone :)

Ok, I have read some information about that..but it says that the max font can be put as 5, the font I have is too small, so how do I make it bigger?

 

Could you also confirm if I only have to change the parameters for the top-left and bottom-right part to make the clicking area bigger?  Will this make the grid inside bigger too?  Can someone point me at which lines I need to edit, I want to get this right first time and done quickly, as I've spent so much time on this previously with no results.

 

Many thanks,

 

Goose.
