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 slim-validation
MadeSimple: slim-validation
Slim Validation is an abstract class to be extended to perform per route validation. Slim Validation allows two types of validation models:
- Validation as a function
- Validation as a middleware
Validation as a function is the recommended use case.
Since Slim v4 has become more flexible there is no longer a straight forward method for extracting the request arguments
as a middleware; this means that getPathRules checks are no longer supported by the validation as a middleware.
In both cases simply extend the abstract class \MadeSimple\Slim\Middleware\Validation and implement the three abstract methods:
getPathRules- allows you to validate the request path.getQueryParameterRules- allows you to validate the query parameters of the request.getParsedBodyRules- allows you to validate the parsed body of the request.
Slim Validation considers requests which violate the path rules as 404 Not Found. Requests which violate either query
parameter or parsed body rules should return as 422 Unprocessable Entity.
For example:
Validation as a function
Validation as a function is the recommended method.
If the request fails path rules validation then a Slim\Exception\HttpNotFoundException is thrown.
If the request fails query parameter or parsed body validation then a MadeSimple\Slim\Middleware\InvalidRequestException is thrown.
To use validation as a function you create the validation class as above and call the validate method in the route's callable, for example:
Validation as a middleware
To use validation as a middleware you create the validation class as above and add it as a middleware for the routes you wish to apply that validation to, for example:
If the request fails validation of either query parameters or parsed body rules then check the container for an invalidRequestHandler otherwise throw MadeSimple\Slim\Middleware\InvalidRequestException. If there is a handler then invalidRequestHandler($request, $response, $errors) is called.
