Imageverification not displayed

Hello all

A really great component - gratulations B) But unfortunately I've a little problem with it...

With my local installation (XAMP) - everything is ok. But if I upload the joomla files on my webspace, the image verification is not displayed on the form site. With Firefox V 2.0.0.4, nothing is shown at the place of the verification "field". In the IE 7.0, the white square with the red X is shown.

What's wrong?!

If you want to have a look, please visit my page.

Thanks for all help.

Regards

Hi Fellyboy,

Is the GD extension for PHP installed? Check PHP.info for the install details.

Bob

Thanks for your answer, bob!

As I can see in the info.php or in the Joomla Backend: yes.

I just attached a printscreen of the info.php file.

Hi,

I see the image has errors, this may be unsupported function is used or some problem under this line :

header("Content-type: image/png"«»);

in file : chrono_verification.php

Please try to test and see which line is the problem, because there is no problems at any servers I worked at at all.

Cheers

Max

Hello

If I type

http://www.nuetzi-schreinerei.ch/joomla/administrator/components/com_chronocontact/chrono_verification.php

in the adressfield of the browser, the following text appears: Die Grafik "http://www.nuetzi-schreinerei.ch/joomla/administrator/components/com_chronocontact/chrono_verification.php" kann nicht angezeigt werden, weil sie Fehler enthält.

Means: the image {imageverification} could not be displayed because the image contains bugs.

On localhost - the image verification is shown correctly.

The line in file chrono_verification.php is exactely the same as you posted, Max.

Thanks!
Markus

Hi Markus,

What you say is just exactly what I said, so I got a result from this error you see, which is that after this line of code I posted there must be some trouble in the code, I guess one of the functions used isn't defined at your live host and so it makes this error!!

So you can use PHP to check if all functions used are at the PHP version you have on the life server.

Max

Hello all

Ah sorry - i didn't understand that - I do appologize😉

Ok with which PHP-Code I can check if all the functions needed for ChronoForms are supported on my life-system?!

Or have you a list wiht all needed functions?! So that I can check in the info.php if they are activated.

Is that what I have to do?! Sorry - I'm a Newcomer B)

Thanks for your reply!
Markus

see here how to check if function exists :

http://www.php.net/function_exists

Ah ok, thanks.

I just changed the CHMOD rights for the components folders on the webserver (now 777). If I want open the chrono_verification.php file on the webserver, the following "message" appears:

<b>Warning</b>:  imagettfbbox(): Could not find/open font in <b>/home/www/web106/html/joomla/administrator/components/com_chronocontact/chrono_verification.php</b> on line <b>21</b><br />

On line 21 I can find: $image_size = imagettfbbox(20, 0, $font, 'X');

Do I have to check this imagettfbbox-function with the script? So I have to create a file named for example function.php with the following content

<?php
if (function_exists('imagettfbbox')) {
    echo "function ok.<br />\n";
} else {
    echo "function not ok.<br />\n";
}
?>

I tested it with the above script - function imagettfbbox is enabled

Thanks!<br><br>Post edited by: Fellyboy, at: 2007/07/06 14:28

Hi,

No, it cant find teh font file or open it, you should have in the dir with this chrono_verification.php a file called default.ttf, can you find it ? can you extract it from the package and upload ?

Cheers

Max

Hello

The default.ttf-file is already in the folder.
I atteched a printscreen on which you can see all the files in the chronoform-folder.
The CHMOD rights from webroot to the dir with the chrono_verification.php are all 777.

[file name=chronodir.zip size=41538]http://www.chronoengine.com/components/com_fireboard/uploaded/files/chronodir.zip[/file]

Hi,

Then try to overwrite it with a fresh one, and assure that you have $font = "default.ttf"; in the chrono_verification.php

Cheers

Max

Hi,

already done. I overwrote it. The "default.ttf" is in the chrono_verification.php (on line 35).

I use the newest version of chrono form. Downloaded from this page.

Can I change something in the backend?

Regards

I just entered the absolute path to the font-file (in different versions)- without any success😟

What about TTF support?! As I can see in the info.php, gd support is enabled.

What about the CHMOD rights? Are there special configurations necessairy?

GD on the server:
GD Support enabled
GD Version 2.0 or higher
FreeType Support enabled
FreeType Linkage with freetype
GIF Read Support enabled
GIF Create Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support enabled

GD localhost:
GD Support enabled
GD Version bundled (2.0.28 compatible)
FreeType Support enabled
FreeType Linkage with freetype
FreeType Version 2.1.9
T1Lib Support enabled
GIF Read Support enabled
GIF Create Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support enabled
XBM Support enabled

Greetings

Hi Markus,

The best way now to test is that you test only the chrono_verification.php with the font file, try getting other font files and try putting the script and the font file in other directories in your server, it should work well anywhere as long as a right path is defined for the font file, I have no idea why this problem occurs for you only but I am sure that with some tests and search you can know where the problem is!

Cheers

Max

Hello

I actually had the same problem. After reading this forum and trying a little I have a solution.
Go to Joomla admin section, Global Configuration/Server.
Copy the Absolute Path and insert it to chrono_verification.php in front of the default.ttf. It means twice and it should be lines 20 and 35. Don't forget about "/" between the path and "default.ttf".
Let me know if it works for you too.

Good luck

Radim

Hi.
I'm having similar problems in getting the image verification to display- any thoughts? I have tried putting an absolute path in front of the default.ttf file as suggested above but no joy.
My site is at http://www.garnffrwdflyfishing.co.uk/joomla and the form is under the enquiries menu tab. Any help would be much appreciated.

Hi,

at chronocontact.php , can we edit the image source at line # 54 to be :

<img src="administrator/components/com_chronocontact/chrono_verification.php">

please let me know the results

Max

Halleluja!

It works!

I deleted all the files on the server - uplaoded all Joomla-files again. And now it seems that this was the solution.

I haven't made the changes in chronocontact.php. Just added the absolute path in chrono_verification.php (on line 20 and 35).

Thanks a lot for all the help!

Nice weekend!
Markus

Nah. Sorry Max that didn't work:(
Any other thoughts?

Sorry Max that has not worked. Any other thoughts?

Hy all

Have you checked the file and folder permissions?! And the absolute path muss be set on both lines in chrono_verification.php (20 and 35).

What about GD support on your webserver?

Regards
Markus

I have tried absolute path and the permissions seem to be OK. What is GD support?

Hi bridgecom,

GD is the PHP graphics extension that's used to create the security images. It's very often installed on server PHP installations - but not always (and not by default).

In Joomla Administrator go to System | System Info and select the PHP Info tab. If you scroll down you will find info on the PHP Extensions. Look for something like the image below.

Bob

Thanks Bob.
I had a look and the GD is correctly enabled. However I still don't see the kaptcha image. Wierd.
Chris

Hi Chris,


It's evening here and I'm just finishing up and off to dinner (been a hard day with the Formula 1 British Grand Prix and the Wimbledon final).

I'll look in the morning and see if I can see a way to create a diagnostic version of the security image creator that will give us a better idea what's happening.

Bob

Hi Chris,

Some things to try.[list]

Check that GD is greater than v 1.6 and has PNG Support enabled (as in the image here)

Edit chrono_verification.php to comment out line 17 (see example below) . Paste {mysite}/administrator/components/com_chronocontact/chrono_verification.php in your browser and see what error messages you get. (Replace {mysite} with the url of your site.)

[/list]

Hi every1,

I have got the same prob as well....

I install the latest version and my server php is GD support.

I try to change the path but it wont work.

when I use firebug, i can see the img there (in code) but it just cant find the img, so is not display in the form...

hope we can slove this prob asap...

thx

Hi frankytsang,

When you say that you can 'see the image' in FireBug what's there? Can you post a screen-shot. Might give some clues.

I'm struggling here and I'm not sure that Max is around at the moment.

Bob

here it is...

you can see the code is there under firebug, but somehow it cant display... normally when your mouse on top of the link, it will display the img, but when i roll over, it seems it cant find the img... strange...

Hi Bob,
Regarding this image verification glitch. I have Community Builder installed and that uses a captcha for registration. This is working fine. Is there maybe some kind of conflict going on with chronoforms?
What do you think?
Chris

Hi frankytsang & Chris,

frankytsang: Thanks for the picture - that's the same as I see in FireBug when the picture works so doesn't take me forward (nice site by the way!)

Chris: It might be Community Builder but I don't see any good reason for that. There are no functions that might be duplicated . . .

I'll scratch my head some more.

Bob

PS I use SecurityImages and that seems to work fine with ChronoForms.

Hi all,

Firstly Iam sorry because Iam away nowdays, I see that this is somehow a problem for too many so lets try this :

in file : chrono_verification.php, there is 2 places where we have $font = "default.ttf", we will do this :

Change lines like this :

$font = "default.ttf";

to be :

$font = dirname(__FILE__)."/default.ttf";

Lets try this solution and see if it works, Please any user has the problem report if this solves it or not🙂

Thanks all!

Max

Fantastic Max! That did the trick for me:) You're the man! I shall now have to contribute.
Chris

It still a no good for me...

I change that 2 lines of code in chrono_verification.php, it happen the same like before, firebug can see the link of the img but seems like it cant display the img...

:(

Hi Franky,

Please try this: [ul[[*]Edit chrono_verification.php to comment out line 17 (see example below) . Paste {mysite}/administrator/components/com_chronocontact/chrono_verification.php in your browser and see what error messages you get. (Replace {mysite} with the url of your site e.g. <!-- w --><a class="postlink" href="http://www.kentoni.com.au">www.kentoni.com.au</a><!-- w --> .)[/list]
Bob

// header("Content-type: image/png");

Hi Bob,

I changed the line to

header("Content-type: http://www.kentoni.com.au/administrator/components/com_chronocontact/chrono_verification.php"«»);

also try absolute path.

but nothing happen, just like before.

:unsure:

Hi Franky,

I'm not making myself clear.

1) comment out the line by putting // before it.

2) go to this url and see if any error messages display.

3) remove the //

Bob

Hi Bob,

I comment out line 17 and it give me this msg

Fatal error: session_start() [<a href='function.session-start'>function.session-start</a>]: Failed to initialize storage module: user (path: /tmp) in /clientdata/clients/k/e/kentoni.com.au/www/administrator/components/com_chronocontact/chrono_verification.php on line 6

I remember something my host told me that about setting absolute path to the temp folder... is that anything to do with it?

Franky

Hi Franky,

Most likely yes, I think that the error message says that the system is trying to store the session data in the /tmp folder but the folder either isn't found or isn't writeable.

Outside my area of competence but I Googled a bit and found a Mambo post that looked as if it might be helpful.

Bob

Hi Bob,

Thanks for the google search, I read it and I already went tho that prob when I install Joomla. My ISP change the session.save_handler to file for me and add the absolute path to session.save_path.

When I open php info, I can see the setting is correct.

It seems the temp folder is there but somehow it cant find it? scarching head in progress:huh:

I try to add

ini_set('session.save_handler', 'files');

before session_start()

still no image display

now when I open http://www.kentoni.com.au/administrator/components/com_chronocontact/chrono_verification.php

it say
The image “http://www.kentoni.com.au/administrator/components/com_chronocontact/chrono_verification.php” cannot be displayed, because it contains errors.

when I comment // header("Content-type: image/png");

it gave me a bunch of error...

seems like I over come the session start problem but it cant read the imagettftext function, any idea?

Franky

ps... am I heading the right direction?

Hi Franky,

Regarding the session issue, could you plz comment any line in chrono_verification.php mentions sessions and test again, lets assure that the image gets work first.

now, please add the fix that worked for other users earlier in the post (bridgecom) and see if the image displays, so now you have fresh file with only sessions lines commented and the hack applied only.

Max

Hi Franky,

I've attached a hacked version of admin.chronocontact.html.php Please go to AntiSpam in ChronoForms Admin and set the option to 'No'.

Then backup your current version and replace it with this one.

When you look at the anti-spam tab it should show some GD diagnostics and a sample image. (It will also hide the 'Yes' option if GD is not found.)

Hi,

To get more 'informative' errors:

Change the header("Content-type: image/png"); into header("Content-type: text/html");
in file chrono_verification.php. Then point your browser directly to that file (ie http://www.yoursite.com/administrator/components/com_chronocontact/chrono_verification.php).
It will show PHP errors on things php cannot handle. This should provide enough input to fix the problem.

Best regards,

Eelco

Hi Eelco,

Thanks, I'll put that into a FAQ here.

Version 2.3 has some new diagnostics on the Anti Spam tab that can also be helpful before digging deeper with this change.

Bob

Same problem here. Cant see the captch image. What chmod does the chrono_verification.php should have?
cheers

Hi ifritz,

Please check FAQ 30 as that may help.

Bob

Thats what i got:

Warning: require_once() [function.require-once]: SAFE MODE Restriction in effect. The script whose uid is 30 is not allowed to access /home/xxx/html/preview/includes/defines.php owned by uid 2027 in /home/xxx/html/preview/components/com_chronocontact/chrono_verification.php on line 10

Probably a wwwrun problem?
What do you think?

Hi, which Chronoforms version is this ?

Hi Ifritz,

This looks like the problem:

SAFE MODE Restriction in effect. The script whose uid is 30 is not allowed to access . . .

You, or you isp, will need to add an entry to the safe-mode settings to let user 30 have the extra access.

Bob

Hi, which Chronoforms version is this ?

Current!

Hi, as Bob said, you will need to check this error with your host, just show them the error and I believe they will have the right solution.

Regards

Max
