Vericode Intermittently Working

I am trying to implement Captcha for my contact form and am having some troubles with the vericode image intermittently not displaying. It seems to be an issue with the vericode.php file return an error sometimes.

Basically, if the user has to hit refresh until it eventually displays. Here is one of the source calls that eForm is using for the src of the image:

http://www.rmsnav.com/manager/includes/veriword.php?rand=39422884

If I browse directly to that URL in Firefox, when the image does not display it just displays the URL again.

If I browse directly to that URL in IE7 and hit refresh multiple times, I eventually get these errors:

Sometimes it takes the user 3-5 refreshes before the image displays. Anyone have any ideas?

I was having a few problems with Vericode and eForm at the beginning of the week too. As it happened Apache didn’t have freetype support and needed recompiling. Maybe put:

<?php
var_dump(gd_info());
?>

in a snippet and see what that kicks out. Maybe you can see that something is set to false that shouldn’t be.

Hope that helps,

Why would that cause intermittent problems? I would think that if something was set to false that shouldn’t be it would cause it to not work at all.

Well, I solved it by editing the veriword.php located in manager/includes:

There is some wonky in the legacy code from the etomite days still in there that I think is causing the problem. I then went into the manager/includes/ttf directory and changed the only font in there to font1.ttf (I don’t see the need to randomly select the font if there is only one font in there. I think this random selection of the font was the cause of it intermitentlly working.

Around line 43 change the directory to:

var $dir_font 	= "ttf/";

Around line 108 I changed the code to comment out the following:

/* pick one font type randomly from font directory */
		$text_font 	= $this->dir_font."font1.ttf";
		
			// added by Alex - read ttf dir
			/*$dir = dir("./ttf");
			$fontstmp = array();
			while ($file = $dir->read()) {
				if($file!="." && $file!="..") {
					$fontstmp[] = './ttf/'.$file;
				}
			}
			$dir->close(); 
			$text_font = sprintf("%s",$fontstmp[array_rand($fontstmp)]);*/

Hope this helps someone and is included in the official release.

Can anyone confirm that this is a bug? Maybe it was unique to my install. I still don’t see the necessity of the random font selection when the basic MODx package only includes one font.

I had a similar problem. I got the error undefined function imagettfbbox(). My problem was that I didn’t have the freetype library. I recompiled php with TTF and it works
