![]() ![]() ![]() With that been said, let’s jump right into the second approach. I thought it was important to bring this up. Notice that this will never be the case in our example, because we have a required rule, if the request input (is_published) is an empty string, the validation will fail before even hitting the boolean rule. ![]() This will cause a false validation, because the empty string will be valuated as a boolean, which make the validation passes. This, is where it gets interested, this last use case could really be confusing, I myself was waiting for null as a return value, but we get a boolean instead (false in this case). Until here it makes perfect sense, “truthy” booleans are true, “falsy” booleans are false, others are just null. $this->toBoolean('not a boolean') // null Understanding how FILTER_NULL_ON_FAILURE flag affect the filter_var function is essential, especially while tackling the second approach as we are going to see later on.įor that reason let me provide you with some examples to demonstrate how the toBoolean method behave under different use cases. When FILTER_NULL_ON_FAILURE flag is set, false is returned ONLY for '0', 'false', 'off', 'no', and '', and null is returned for all non-boolean values. Return filter_var($booleable, FILTER_VALIDATE_BOOLEAN, FILTER_NULL_ON_FAILURE) įILTER_VALIDATE_BOOLEAN tries to be smart, recognizing words like 'Yes', 'No', 'Off', 'On', 'true' and 'false', and is not case-sensitive when validating strings.įILTER_VALIDATE_BOOLEAN returns true for '1', 'true', 'on' and 'yes'. 'is_published' => $this->toBoolean($this->is_published), Protected function prepareForValidation() So in our small example here, we will try to convert the is_published value to an actual boolean, and merge it back to the original request. Like its name reveals, this method allows us to add new request inputs or update existing request inputs before going through the validation rules. Let’s start with what I think it’s a more easy approach to implement, it’s what Laravel calls “Preparing Input For Validation”, and that’s done by using prepareForValidation() method. The first approach - use prepareForValidation method So, how can we handle this?īefore diving in, I want to show you the logic Laravel uses to validate booleans internally, you can actually see that in validateBoolean() method located in Illuminate/Validation/Concerns/ValidatesAttributes. Let’s also say that is_published value coming to us from the client is 'true' or 'false'.Īt this point we already know that validation wouldn’t pass. PostRequest, for simplicity purposes, has a single request input that, first, is required, and second, is boolean, and this input is named is_published. Form requests are custom request classes that encapsulate their own validation and authorization logic. To deeply understand why this is happening, let’s go through an example, let’s say that we have a form request that we call PostRequest. But, that’s not the case, instead, you will be hit with this beautiful error message 'The inputName field must be true or false.' You would expect, as I did, that this will just work out of the box and Laravel validator will treat them as boolean. There are currently several supported drivers: Bcrypt and Argon2 (Argon2i and Argon2id variants).This post was originally published on my personal blog on 30th December 2021.Įvery once in a while you come across a situation where you need to validate a request input as a boolean, and the input value is 'true' or 'false' (notice that I wrapped the values inside single quotes to indicate that those are actually strings). The default hashing driver for your application is configured in your application's config/hashing.php configuration file. The longer an algorithm takes to hash a password, the longer it takes malicious users to generate "rainbow tables" of all possible string hash values that may be used in brute force attacks against applications. If you are using one of the Laravel application starter kits, Bcrypt will be used for registration and authentication by default.īcrypt is a great choice for hashing passwords because its "work factor" is adjustable, which means that the time it takes to generate a hash can be increased as hardware power increases. The Laravel Hash facade provides secure Bcrypt and Argon2 hashing for storing user passwords. Determining If A Password Needs To Be Rehashed.Verifying That A Password Matches A Hash. ![]()
