Compatibility with Symfony
|
||||
==========================
|
||||
|
||||
If you are using Symfony `< 2.8`, you should use version `1.*`
|
||||
| CaptchaBundle | Symfony |
|
||||
|:---------------:|:-------:|
|
||||
| 3.* | 5.* |
|
||||
| 2.* | \>= 2.8 |
|
||||
| 1.* | < 2.8 |
|
||||
|
||||
If you are using Symfony `>= 2.8`, you should use version `2.*`
|
||||
|
||||
Installation
|
||||
============
|
||||
|
||||
### Step 1: Download the GregwarCaptchaBundle
|
||||
|
||||
Ultimately, the GregwarCaptchaBundle files should be downloaded to the
|
||||
'vendor/bundles/Gregwar/CaptchaBundle' directory.
|
||||
|
||||
You can accomplish this several ways, depending on your personal preference.
|
||||
The first method is the standard Symfony method.
|
||||
|
||||
***Using Composer***
|
||||
|
||||
Use composer require to download and install the package.
|
||||
Use composer require to download and install the package.
|
||||
At the end of the installation you can automaticly create the configuration thanks to the Symfony recipe.
|
||||
|
||||
``` bash
|
||||
composer require gregwar/captcha-bundle
|
||||
```
|
||||
|
||||
***Using the vendors script***
|
||||
|
||||
Add the following lines to your `deps` file:
|
||||
|
||||
```
|
||||
[GregwarCaptchaBundle]
|
||||
git=http://github.com/Gregwar/CaptchaBundle.git
|
||||
target=/bundles/Gregwar/CaptchaBundle
|
||||
version=origin/2.0 <- add this if you are using Symfony 2.0
|
||||
```
|
||||
|
||||
Now, run the vendors script to download the bundle:
|
||||
|
||||
``` bash
|
||||
$ php bin/vendors install
|
||||
```
|
||||
|
||||
***Using submodules***
|
||||
|
||||
If you prefer instead to use git submodules, then run the following:
|
||||
|
||||
``` bash
|
||||
$ git submodule add git://github.com/Gregwar/CaptchaBundle.git vendor/bundles/Gregwar/CaptchaBundle
|
||||
$ git submodule update --init
|
||||
```
|
||||
|
||||
### Step 2: Configure the Autoloader
|
||||
|
||||
If you use composer, you can skip this step.
|
||||
|
||||
Now you will need to add the `Gregwar` namespace to your autoloader:
|
||||
|
||||
``` php
|
||||
<?php
|
||||
// app/autoload.php
|
||||
|
||||
$loader->registerNamespaces(array(
|
||||
// ...
|
||||
'Gregwar' => __DIR__.'/../vendor/bundles',
|
||||
));
|
||||
```
|
||||
### Step 3: Enable the bundle
|
||||
|
||||
Finally, enable the bundle in the kernel:
|
||||
|
||||
```php
|
||||
<?php
|
||||
// app/appKernel.php
|
||||
|
||||
public function registerBundles()
|
||||
{
|
||||
$bundles = array(
|
||||
// ...
|
||||
new Gregwar\CaptchaBundle\GregwarCaptchaBundle(),
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
Configuration
|
||||
=============
|
||||
|
||||
Add the following configuration to your `app/config/config.yml`:
|
||||
If you made the configuration automaticly trough the Symfony recipe, you should have the following config file `/config/packages/gregwar_captcha.yaml`
|
||||
|
||||
Otherwise you can create it manually `/config/packages/gregwar_captcha.yaml` with the following default configuration:
|
||||
``` yaml
|
||||
gregwar_captcha: ~
|
||||
```
|
||||
|
||||
Usage
|
||||
=====
|
||||
|
||||
You can use the "captcha" type in your forms this way:
|
||||
|
||||
```php
|
||||
``` php
|
||||
<?php
|
||||
use Gregwar\CaptchaBundle\Type\CaptchaType;
|
||||
// ...
|
||||
$builder->add('captcha', CaptchaType::class); // That's all !
|
||||
// If you're using php<5.5, you can use instead:
|
||||
$builder->add('captcha', 'Gregwar\CaptchaBundle\Type\CaptchaType');
|
||||
// ...
|
||||
```

As URL
|
||||
============
|
||||
To use a URL to generate a captcha image, you must add the bundle's routing configuration to your app/routing.yml file:
|
||||
|
||||
``` yaml
|
||||
gregwar_captcha_routing:
|
||||
resource: "@GregwarCaptchaBundle/Resources/config/routing/routing.yml"
|
||||
```
|
||||
|
||||
This will use the bundle's route of "/generate-captcha/{key}" to handle the generation. If this route conflicts with an application route, you can prefix the bundle's routes when you import:
|
||||
|
||||
``` yaml
|
||||
gregwar_captcha_routing:
|
||||
resource: "@GregwarCaptchaBundle/Resources/config/routing/routing.yml"
|
||||
prefix: /_gcb
|
||||
```
|
||||
|

Since the session key is transported in the URL, it's also added in another session array, under the `whitelist_key` key, for security reasons
