FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package captcha
Captcha
Captcha is a Statamic addon that makes a classic captcha available for Statamic forms.
Features
This addon does:
- Provide Captcha Image
- Provide Tags to use in your Forms
Requirements
| Statamic | PHP |
|---|---|
| 5.x | 8.2+ |
| 6.x | 8.3+ |
The same release works on both major versions — the addon does not use any
Statamic APIs that changed between 5 and 6. It requires the gd, mbstring
and fileinfo PHP extensions (pulled in via gregwar/captcha).
Accessibility Notice
Please note that this captcha requires vision to solve. This captcha provides an image with a 4-character string that needs to be entered in the coresponding form field.
How to Install
You can search for this addon in the Tools > Addons section of the Statamic control panel and click install, or run the following command from your project root:
How to Use
1. Install the addon
Install the Captcha addon into your Statamic project as described in How to Install.
2. Add new validation rule
To use the Captcha in your form you need to add a new validation rule.
Do this by running php artisan make:rule VerifyCaptcha in your terminal.
The new rule should contain these methods:
public function passes($attribute, mixed $value): bool
{
try {
if (strtolower($_SESSION['phrase']) === strtolower($value)) {
Captcha::refreshCaptcha();
return true;
} else {
return false;
}
} catch(\Exception $e) {
return false;
}
}
public function message(): string { return '__(validation.verify_captcha)'; }
The message handles the error messages you may want to define in resources > lang.
Extending App Service Provider Extending the App Service Provider is no longer necessary.
4. Add your form field
Your form needs to contain a text form field with the validation rules required and captcha.
5. Include the captcha into your form template
The form template should include the {{ refresh_captcha }} tag to generate a new captcha on reloading the form to get a fresh one every time.
Your form field template should include an img tag with the src of {{ captcha_image }}.
This that will provide you with the image URL.
You can also add a button which will let the user generate another captcha image.
<button type="button" data-refresh-url="{{ captcha_refresh_url }}">generate new captcha image</button>
Now you should be all set to use the Captcha on your own Website.
Error Messages & Translations
The failure message of the captcha validation rule ships translated for:
de_DE · en_GB · es_ES · fr_FR · it_IT · nl_NL · pl_PL · pt_BR
Statamic uses the short lang code of a site (de) unless the site config sets a
full lang (de_DE), so each language is registered under both — you do not
have to configure anything. Sites in a language that is not listed fall back to
en.
Overriding a message
Either define captcha in your own lang/{locale}/validation.php — Laravel
checks the app's own files first:
Or publish the addon's files and edit them in place:
