Forum Index / General / Captcha field doesn't display

Hello,

I'm loving FormHandler, but I can't get a captcha field to work. I tried it in a form I had made which was working fine and when I included the captcha code none of the form displayed. So now I'm using the code straight from the manual, the only thing I change is the path to the class. I use this path in the code of the form that works without the captcha field, so I know it is correct.

When I use this code, nothing at all displays in the browser.

<?php

// include the class
include("../../FormHandler/class.FormHandler.php");

echo "here";

// make a new $oForm object
$oForm = new FormHandler();

// a textfield
$oForm->CaptchaField("Verify the code", "code");

// submitbutton beneath it
$oForm->submitButton("Save");

// set the 'commit after form' function
$oForm->onCorrect("FH_RUN");

// send the form to the screen
$oForm->flush();

// function to show a message
function FH_RUN($aData)
{
return "You entered the correct code ". $aData["code"];
}
?>

Any help is greatly appreciated.

Steve

Changed at 22 February 09 / 20:13 I did copy your exact code to here http://www.jwiegel.com/FH/test.php if you visit this url can you see the captcha code?

Yes, it does display. So what can be different/missing with mine?

Is your error reporting on? try this in: ..\formhandler\includes\class.Validator.php on line 438 replace require('../'.FH_FHTML_DIR.'securimage/securimage.php'); with: require($_SERVER['DOCUMENT_ROOT'] . FH_FHTML_DIR . 'securimage/securimage.php');

Did you enable error-reporting in PHP? A blank screen sometimes means an error occurred and PHP configuration prevents you from seeing the error.

Try to add these lines on top of your script (development use only)

<?php
error_reporting( E_ALL );
ini_set( 'display_errors', 1 );
?>

Maybe an error shows up now?
Also take a look at what phpinfo() tells you. To use the CaptchaField GD support must be activated in PHP.

replace require('../'.FH_FHTML_DIR.'securimage/securimage.php'); with: require($_SERVER['DOCUMENT_ROOT'] . FH_FHTML_DIR . 'securimage/securimage.php');[/quote] I had exactly the same. Check your HTML source. The reference to the image is probably not correct. FH_FHTML_DIR, in my case (IIS shared server) referenced to E:\wwwroot\etc., so a no go. $_SERVER['...'] the same. I hardcoded the path 'FHTML/securimage/securimage.php', for testing, and voila. This works if the testing file is in the same folder as class.FormHandler.php, obviously.

OH... and be aware: This PATH is coded in the class.Validator.ph (438) AS WELL AS class.FormHandler.php (369)

maybe use the last version where this is replaced by: require(FH_FHTML_INCLUDE_DIR . 'securimage/securimage.php');
