insert variable into function

[patrickMcD]

I appreciate your taking a quick look at this. This template takes a couple of variables sent through the url and then generates a pdf for a ticket to one of our shows. What I am doing is setting up a random ad placement. The following code looks at the folder with the ads and selects one to include in the pdf:

//create variable for ad placement
$imglst='';
$img_folder="ticketimages/ads/";
mt_srand((double)microtime()*1000);
$imgs =dir($img_folder);

while($file = $imgs->read()){
	if (eregi("gif",$file) || eregi("jpg", $file) || eregi("png", $file))
     $imglist .= "$file ";
 } closedir($imgs->handle);

  //put all images into an array
 $imglist = explode(" ", $imglist);
 $no = sizeof($imglist)-2;

 //generate a random number between 0 and the number of images
 $random = mt_rand(0, $no);
 $adimage = $imglist[$random];

The template then queries the database for information on the ticket purchases and then assembles that with the image files that comprise the ticket.

Then on line 198 I want to insert the image that the code above retrieved with the use of a function

function Image($file, $x=null, $y=null, $w=0, $h=0, $type='', $link='')

So I thought this might work replacing hte literall string with the variable $usethisimage

$this->Image($usethisimage,15,235,180,20,'jpg','http://www.someplace.net');

But that didn't work. If I can get the variable into the function It will work.

Any ideas?


Here is the entire template:

<?

function proper($txt)
{
	$txt = strtolower($txt);
	$txt = ucwords($txt);
	return($txt);
}

require("fpdf.php");

//create variable for ad placement
$imglst='';
$img_folder="ticketimages/ads/";
mt_srand((double)microtime()*1000);
$imgs =dir($img_folder);

while($file = $imgs->read()){
	if (eregi("gif",$file) || eregi("jpg", $file) || eregi("png", $file))
     $imglist .= "$file ";
 } closedir($imgs->handle);

  //put all images into an array
 $imglist = explode(" ", $imglist);
 $no = sizeof($imglist)-2;

 //generate a random number between 0 and the number of images
 $random = mt_rand(0, $no);
 $adimage = $imglist[$random];

$usethisimage = $img_folder.$adimage;

I'm not good with OO, but can't you just overload the AliasNbPages() method to accept a string parameter, and send $usethisimage to the PDF class that way?

Huh? You tell me. I hope so. How would I go about that?
