gregwar / captchabundle Goto Github PK

I added the captcha on my form with this config

->add("captcha","captcha", array(
                    'length' => 5,
                    'height' => 25,
                    'quality' => 90,
                    'reload' => true,
                    'invalid_message' => 'O valor digitado não corresponde com a imagem.'))

when i click renew it does not change the image chrome give me this error

GET data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD//gA7Q1JFQVRPUjogZ2QtanBl…6qfD2V01FKinypJXu9E7q+urV9G1dLS+9yiiivXPogooooAKKKKAP/2Q==?n=1358825417818

if i use as_url i get this error

GET http://localhost/AcheiaVan/web/app_dev.php/generate-captcha/gcb_captcha 404 (Not Found)

i'm confused, but i can not use my custom font, i put file ttf in gregwar/captcha-bundle/gregwar/CaptchaBundle/Generator/Font/
but when i try to get img (as_url used) i've got :
imagettfbbox(): Could not find/open font in /my path/vendor/gregwar/captcha/Gregwar/Captcha/CaptchaBuilder.php line 254
i'm inspect what's happened and found
class (placed in vendor/gregwar/captcha/Gregwar/Captcha)CaptchaBuilder->build() at line 321 Builder looking for FONTS in Captcha folder, not in CaptchaBundle..
It's seems strange(i installed bundle and i put font file in Bundle dir)

Hello,

I'm trying to validate captcha with an ajax request and allways with the same response, the form is invalid. Do you know how to do this?

Sorry for my english.

Regards

$criteria = sprintf('>= now - %s minutes', $this->expiration);

Here you select files that new, but must select old files. And there is no implementation for "minutes" but "minute".
So the string must be:
$criteria = sprintf('<= now - %s minute', $this->expiration);

Also I think bundle in a future must provide ability to:

1. setup in config file $charset = 'abcdefghijklmnopqstuv23456789'; For example I want to use only digist 1234567890. Here is no implementation.
2. setup the font in config file for $font = DIR.'/Font/captcha.ttf';
3. public function validate(FormInterface $form) provide method where value changed in session only if i type it correct in a form. But what about if I want to change value even if it was wrong. And in this case my captcha field must be clear on submit.

Thank you for your bundle.

Add empty ALT to captcha image to make it pass HTML5 validator. An ALT attribute is always required for an image. If no alternative text has to be displayed, then this must be empty. Another option would be to put purely "captcha"

Ignore character case, when comparing captcha-codes. Adding strtolower() to niceize() in class CaptchaValidator would do it.

hello,
can you configure the bundle to be appropriate with "composer"

Hi,

I would like to use this bundle but i can't install it.

I copied the bundle manually on the repertory vendor\bundles\Gregwar\CaptchaBundle
I added the namespace in autoload.php: 'Gregwar' => DIR.'/../vendor/bundles',
I added the bundle in AppKernel.php: new Gregwar\CaptchaBundle\GregwarCaptchaBundle(),
I had the configuration line in config.yml: gregwar_captcha: ~

But the aplication can't load the resource config.yml because of the line gregwar_captcha: ~

Any idea?

Please provide an option to disable captcha (for example to use in dev environment, or in debug)

Hi. I have this issue on SF 2.0.12.

Catchable Fatal Error: Argument 1 passed to Gregwar\CaptchaBundle\Type\CaptchaType::__construct() must be an instance of Symfony\Component\HttpFoundation\Session\Session, instance of Symfony\Component\HttpFoundation\Session given, called in /home/pchludzinski/www/d7/Symfony/app/cache/dev/appDevDebugProjectContainer.php on line 234 and defined in /home/pchludzinski/www/d7/Symfony/vendor/bundles/Gregwar/CaptchaBundle/Type/CaptchaType.php line 37

Captcha distortion still well recognized
Need to increase the degree of distortion or allow to control the degree of distortion in the configuration files

Perhaps this article will help a bit

Hy!

I'm use the CaptchaBundle and I need customize the error message.

Thanks

The new loaded image is not displaying (probably wrong path?).

Hi,
Bundle works fine except from the two options: charset and quality.
When I try to use one of them I get: The option "quality" does not exist 500 Internal Server Error - CreationException

Here is my configuration:

->add('captcha', 'captcha', array(
                    'width' => 200,
                    'height' => 50,
                    'length' => 6,
                    'as_file' => true,
                    'quality' => 30,
                ))

Any ideas what can be wrong?

BTW. There should be also and 'errorMessage' option to customize error message.

In Form Theming section:

{% block captcha_widget %}
    {% spaceless %}
        <img src="{{ captcha_code }}" title="captcha" width="{{ captcha_width }}" height="{{ captcha_height }}" />
        {{ form_widget(form) }}
    {% spaceless %} // It must be "endspaceless"
{% endblock %}

Anyway, I like this bundle very much. Nice job :).

Hello, I have follow the readme instructions and I havent been able to show up the image in my PROD enviroment. Locally is working correctly, but in my prod server is not showing up the images.

http://bajacupcakes.com/

I have as_ulr = true.

Added the routing in my routing.yml

And in my security.yml I added the exception to allouw acces to the route.

In my config I have the as

gregwar_captcha:
as_url: true

But still I am getting the same result.

Cheers.

If the captcha-code was not correct, do not keep the old value in the textfield of the reloaded form.

I thought we could create another repository which would only contain the generation logic and be Symfony-independant

This could be done easily by splitting the CaptchaGenerator class, and creating a CaptchaGeneratorService for instance which would inherits from the generator and add Symfony specific logic

@jeremylivingston: what do you think?

I'll wait for your changes to avoid painful conflicts and I think I will work on this

Increase image quality for better readability:

• Make image-quality configurable. Quality value 15 looks quite ugly.
• Render the captcha in double size and then resize it down, which gives a sharper distortion effect.

Hi,

I just installed the bundle according to the readme, using Composer, in Symfony 2.1.0 RC1, and I'm getting this error:

Fatal error: Declaration of Gregwar\CaptchaBundle\Type\CaptchaType::buildView() must be compatible with that of Symfony\Component\Form\FormTypeInterface::buildView() in [...]/vendor/gregwar/captcha-bundle/Gregwar/CaptchaBundle/Type/CaptchaType.php on line 122

I read that this is the error you get when you installed the master branch in Symfony 2.0.x, but I'm definitely running a brand new install of Symfony 2.1 and I added "gregwar/captcha-bundle": "1.0.0" to composer.json.

Do I miss something?

Thanks you,

Philippe

Thanks you for this bundle.

I have to override the bundle to implement arithmetic captcha ( 3+ 13 ) = ?. Is there any easy way to do this ?

When I remove captcha field, and fill then submit. Form is valid.

Can you tell me what issue happens ?

Hi folks, I'm on this issue since 2 days and i'm really stuck! Here is the thing.

There is a simple "sign-up" form which use the captcha type.

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('email', 'email', [
                'label' => 'all.email'
            ])
            ->add('plainPassword', 'repeated', [
                'type'            => 'password',
                'invalid_message' => 'all.password_mismatch',
                'first_options'   => ['label' => 'all.password'],
                'second_options'  => ['label' => 'all.password_confirm']
            ])
            ->add('captcha', 'captcha')
            ->add('submit', 'submit', [
                'label' => 'all.submit'
            ])
        ;
    }

Using my Apache Web Server, everything is fine. When I type a bad captcha I got insulted, when I type a good one my account is created.

Using the PHP built-in web server app/console server:run I always get insulted!

Using Apache, I've figured out the following workflow:

1. A new captcha is generated
2. The captcha is stored in the Session
3. Form submission (the page is reloaded)
4. The captcha is retrieve from the session (and is equal to the one stored on step 2.)
5. The retrieved captcha is compared to the form input value
6. Done

Using PHP Web Server:

1. A new captcha is generated
2. The captcha is stored in the Session
3. Form submission (the page is reloaded)
4. The captcha is retrieve from the session --> but this time different form the one stored on the step 2!!
5. The retrieved captcha is compared to the form input value
6. Done

Any ideas?

Thanks.

The "arguments" injection in the services.yml file is really getting bigger and bigger, it should be cleaner

The ida of splitting logic was to extract the logic into another repo, in order to be able to use it for other purpose/framework than Sf2

Gregwar\Captcha ? Gregwar\CaptchaBuilder ?

Can you tag your releases so that users can keep up to date without relying on dev-mater?

Thanks!

I want to specify the validation group in which the capture must be validated. Usualy I do this via a constraint. How can I do this using the captcha?

Hello,
when I open multiple tabs in a browser, only the last captcha value is valid. It seems like that captcha codes and tokens (probably!) are stored in session without any identification key.

Thanks for your attention.

   $builder->add('captcha', 'captcha', array(
        'required' => false,
        'width' => 220,
        'height' => 50,
        'length' => 8,
        'keep_value' => false,
        'as_url' => true,
        'reload' => true,
        'invalid_message' => 'The captcha code is invalid.'
    ));

Here, I am setting the length to 8, as_url and reload to true as I want to provide a link to reload captcha. But, it defaults to 5. It works when as_url and reload are false, though. Am I doing something wrong? Btw, it is really great bundle. Thanks.

It would be great to have the possibility to add a link below the input field to renew the captcha image through an AJAX call, just in case the user does not understand the first image.

The configuration should also be transported in the session IMO

Hi, i'm on a single page application as front and Sf 2.4 as backend. I'm not using sf form.. how can i use this bundle without using sf form?

Fatal error: Declaration of Gregwar\CaptchaBundle\Type\CaptchaType::getDefaultOptions() must be compatible with that of Symfony\Component\Form\FormTypeInterface::getDefaultOptions() in /home/animalsmc/domains/animals-mc.com/public_html/Symfony/vendor/bundles/Gregwar/CaptchaBundle/Type/CaptchaType.php on line 119

And i am aware i have to use the 2.0 brach, but can you please note in the docs how to do it ?
Because i use sf2 2.0.15 i use the deps file, so how do i tell it to take the 2.0 branch ?

I followed the steps, and for the second time (I just assumed I had miss something the first one, now I do want to know what I am missing), I am getting this: Fatal error: Call to undefined function Gregwar\CaptchaBundle\Generator\imagecreatetruecolor() in […]. Any idea?

I have installed the captcha bundle and it awsom. Just when I enter a wrong code in the captcha the invalid message is not rendering when submiting the form.

Any idea what can it be.

Cheers and great job.

In symfony 2.2 "Bad code value" remains untranslated. Symfony 2.2 ignores translations for validator.

What if I need background colour to be immutable? For example I want only white background for captcha. Can you help me with option?

Once you've copied a CAPTCHA, if you did a mistake on a form, it's really painful to copy it again and again

Maybe we could add an option to consider that an user is an human once he typed a correct CAPTCHA, this would be an int telling how many form can be submitted after each captcha (humanity?)

if submitted form is invalid, but captcha is valid - do not validate captcha (and do not render) on next submits while form is invalid

Hi,

I've just implemented this bundle in an app of mine. I noticed that the paged rendering was significantly slower, so I did some profiling: http://imgur.com/T82ibjr

The image distortion is very expensive. I did some load testing on a real server and here are the results :

With distortion (blue: number of clients, green: load time): http://imgur.com/rAUXG0P

Without distortion (blue: number of clients, green: load time): http://imgur.com/ZtWvzaE

The load time is stable without distortion, but it's really not scalable with distortion enabled.

I'm using quite big captchas with hight jpeg quality:

gregwar_captcha:
    quality: 60
    background_color: [217, 237, 248]
    height: 90
    width: 260
    charset: abcdefhjkmnptuvwxy234689

Is that a known issue? Do you have any idea on how this could be improved?

Keeping the captcha value between two requests should be configurable

Can we create a Github service hook for this repository as detailed here?
https://packagist.org/about

It would be nice to start tagging versions of this repository and creating development branches as well. Adding this service hook will allow these updates to be pulled automatically.

Please let me know if you have questions. Thanks!

If you are using Varnish Memcahe ESI or other hell's cache, we need this small fix in widget render, that's needed for using as_url option( GET requests cache problem):
{% block captcha_widget %}
.....
< img id="{{ image_id }}" sr c="{{ captcha_code }}?n={{random() }}" alt="" title="captcha" width="{{ captcha_width }}" height="{{ captcha_height }}" />

Font should be configurable

Charset used should be configurable

Hello, I'm currently using Gregwar Captcha Bundle for my registration form. Now I've added it to another form (contact form). The problem is that when I try to submit the registration form, it's not accepting the captcha shown as correct, because the captcha is used one more time, after registration form.

I have a page, where I have Registration on every page + Contact form on every page. So any ideas are welcome.

an additional: color_text option needed! i saw pull request for merge commit in other ticket, but i fetch Bundle yesterday, and this options does not exist(probably merge are not completed)
builder->addEventListener(FormEvents::POST_SUBMIT(instead POST_BIND/BIND), array($validator, 'validate'));

I'am using your Bundle and it works perfectly! But as I come to writing unit tests for my forms I ran into this error:

# phpunit -c app/phpunit.xml.dist src/Acme/AcmeBundle/Tests/Form/
PHPUnit 3.7.19 by Sebastian Bergmann.

The Xdebug extension is not loaded. No code coverage will be generated.

There was 1 error:

1) Acme\AcmeBundle\Test\Form\Type\ContactTypeTest::testSubmitData with
 data set #0 (array('Peter', 'nice!', 'nice!', 'test'))
Symfony\Component\Form\Exception\InvalidArgumentException: Could not load type "
captcha"

Is there a way to make this Bundle work in the test envoirement?
