To override the form_errors() function in Twig in Symfony, you can create a new Twig extension and add your custom implementation of the form_errors() function.
Here is an example of how you can create a custom Twig extension in Symfony:
- Create a new Twig extension class by extending the AbstractExtension class and implementing the getFunctions() method. This method should return an array of Twig functions, including your custom form_errors() function.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |
// src/Twig/CustomFormErrorsExtension.php
namespace AppTwig;
use SymfonyComponentFormFormView;
use SymfonyComponentFormExtensionCoreTypeFormType;
use TwigExtensionAbstractExtension;
use TwigTwigFunction;
class CustomFormErrorsExtension extends AbstractExtension
{
public function getFunctions()
{
return [
new TwigFunction('form_errors', [$this, 'customFormErrors'], ['is_safe' => ['html'], 'needs_context' => true]),
];
}
public function customFormErrors(array $context, FormView $form, array $options = [])
{
// Add your custom implementation of form_errors() here
// You can access the form errors using $form->vars['errors'] and modify the output accordingly
// Return the modified errors HTML
}
}

- Register your custom Twig extension as a service in services.yaml:
1 2 3 4 5 |
# config/services.yaml
services:
AppTwigCustomFormErrorsExtension:
tags: ['twig.extension']
|
- Now you can use your custom form_errors() function in your Twig templates:
1
|
{{ form_errors(form) }}
|
Remember to modify the customFormErrors() method in your CustomFormErrorsExtension class to suit your specific requirements and modify the output of the form errors as needed.
