Captcha Font color not changing

Captcha Font color not changing

Have the captcha files working on a couple of sites, but for one no matter what color settings I use the font does not change color. At the moment it is yellow. The site is on the same server as the other that are working, so its not the server. All the code is exactly the same as the others that work, except the changes associated with the form fields etc.

Any idea what it could be?. I noticed that in the WAVT_CaptchaSecurityImages.php file at the bottom of the code, it already has settings there already. yes, I have even tried changing the color settings here, but still no joy. Could it be something to do with the GDLibrary version 2.0.34 or Freetype version 1.3 ?

Check out the WA_Globals.php file
in the WA_Globals directory....

php:
$WAGLOBAL_Captcha_Width = "120" ;

  $WAGLOBAL_Captcha_Height = "24" ;
  $WAGLOBAL_Captcha_Characters = "5" ;
  $WAGLOBAL_Captcha_Font = "Fonts/MOM_T___.TTF" ;
  $WAGLOBAL_Captcha_BG = "cccccc" ;
  $WAGLOBAL_Captcha_Noise = "000000" ;
  $WAGLOBAL_Captcha_Text = "fffc00" ;
  $WAGLOBAL_Captcha_BG_transparent = "0" ;

Also make sure the captcha image tag passes all of the WA_Globals variables:

php:
<img  src="WA_ValidationToolkit/WAVT_CaptchaSecurityImages.php?noisecolor=<?php echo $WAGLOBAL_Captcha_Noise?>&bgcolor=<?php echo $WAGLOBAL_Captcha_BG?>&textcolor=<?php echo $WAGLOBAL_Captcha_Text?>&transparent=<?php echo $WAGLOBAL_Captcha_BG_transparent?>&characters=<?php echo $WAGLOBAL_Captcha_Characters?>&width=<?php echo $WAGLOBAL_Captcha_Width?>&height=<?php echo $WAGLOBAL_Captcha_Height?>&font=<?php echo $WAGLOBAL_Captcha_Font?>&gridfreq=0" alt="security code" />

captcha font color

My WA Globals are set to this:

$WAGLOBAL_Captcha_Width = "200" ;
$WAGLOBAL_Captcha_Height = "40" ;
$WAGLOBAL_Captcha_Characters = "5" ;
$WAGLOBAL_Captcha_Font = "Fonts/MOM_T___.TTF" ;
$WAGLOBAL_Captcha_BG = "ffffff" ;
$WAGLOBAL_Captcha_Noise = "eeeeee" ;
$WAGLOBAL_Captcha_Text = "ff0000" ;
$WAGLOBAL_Captcha_BG_transparent = "0" ;

You would think the text would be 'red'. Well its currently 'Blank' If I change the 'Captcha_Text = "000000" you would think it is Black?. Well its yellow????

Take a look at the example:
contact_us.php

This is all as it should be: (not edited)

<img src="WA_ValidationToolkit/WAVT_CaptchaSecurityImages.php?noisecolor=<?php echo $WAGLOBAL_Captcha_Noise; ?>&bgcolor=<?php echo $WAGLOBAL_Captcha_BG; ?>&textcolor=<?php echo $WAGLOBAL_Captcha_Text; ?>&transparent=<?php echo $WAGLOBAL_Captcha_BG_transparent; ?>&characters=<?php echo $WAGLOBAL_Captcha_Characters; ?>&width=<?php echo $WAGLOBAL_Captcha_Width; ?>&height=<?php echo $WAGLOBAL_Captcha_Height; ?>&font=<?php echo $WAGLOBAL_Captcha_Font; ?>" alt="security code" />

On another site (on the same server) the font will not show up at all.

I have also tried another captcha tool, this time a dreamweaver extension I have just purchased and that works fine, just a few tweeks to integrate UE and all should be well.

It seems that this solution pack works when it feels like it and sometime when it works ignores some settings. The whole point of this solution was I think to save people time?

I would suggest getting this into a dedicated extension and integrated say within UE. makes sense!

In the WA_ValidationToolkit/WAVT_CaptchaSecurityImages.php file, line 168 should be:

$textcolor = isset($_GET['textcolor']) && $_GET['textcolor'] != "" ? $_GET['textcolor'] : '000000';


can you check that yours is set properly.

captcha is a built into the CSS Form Builder extension.

Captcha text color not changing

I had a look at the code you mentioned and all seems to be correct. However I decided to set the form again using all the code from the orginal contact page you provide.

You will notice from the example page:
contact_us.php

that the Text color is still yellow. If you view source it has the text color as 'Black' ???

I am not too sure as to what is going on.

Not the correct technical approach, but if it were me I would search (find/replace) the the 'Entire Current Local Site' > 'Source Code' for ' ffff00 ' to see where that colour is specified, then try changing the settings there, assuming that it's in a related page.

Captcha text color not changing

I have already checked (just in case) something within a style could have caused the issue. No, nothing at all. When I change the font color it also sometimes disappears. Its as though it is ignoring any styling color related to the font. For example I have just changed the Font, Captcha BG and Captcha Noise to ff0000 (red) and hey the font now completely disappears, even though it is set to Black and showing as Yellow, its gone!!! ????

That is weird.

If you want to try my settings, I have attached a copy of my WA_ValidationToolkit > WAVT_CaptchaSecurityImages.php (which is where the captcha image settings are stored).

Back up your existing file, then try the attached. This will help to narrow down the causes of your problem.

Let us know how you get on!
