Ajv generates code to turn JSON Schemas into super-fast validation functions that are efficient for v8 optimization.

Rose therefore recommended "explicit consistency checks in a protocol ... even if they impose implementation overhead".

openVALIDATION enables programming of complex validation rules using natural language, such as German or English.

"detail": [ { "loc": [ "body", "name" ], "message": "Field required" }, { "loc": [ "body", "email" ], "message": "'not-email' is not an 'email'" } ]

x-ov-rules: culture: en rule: | the location of the applicant MUST be Dortmund

Input check = Tests the user input, as opposed to some internal data structure or the output of a function.

All validators can be used independently. Inspried by functional programming paradigm, all built in validators are just functions.

FormValidation.validators.creditCard().validate({

FormValidation.formValidation(formElement

It's worth pointing out that filenames can contain a newline character on many *nix systems. You're unlikely to ever run into this in the wild, but if you're running shell commands on untrusted input this could be a concern

1- Validation: you “validate”, ie deem valid or invalid, data at input time. For instance if asked for a zipcode user enters “zzz43”, that’s invalid. At this point, you can reject or… sanitize. 2- sanitization: you make data “sane” before storing it. For instance if you want a zipcode, you can remove any character that’s not [0-9] 3- escaping: at output time, you ensure data printed will never corrupt display and/or be used in an evil way (escaping HTML etc…)

This style of validation most closely follows WordPress’ whitelist philosophy: only allow the user to input what you’re expecting.

What Is Input Validation and Sanitization? Validation checks if the input meets a set of criteria (such as a string contains no standalone single quotation marks). Sanitization modifies the input to ensure that it is valid (such as doubling single quotes).
