You may need to keep input from one request until the next request. For example, you may need to re-populate a form after checking it for validation errors. Flashing Input To The Session 1Input::flash(); Flashing Only Some Input To The Session ...
Input validationis a technique to use to protect the main query logic from malformed or unexpected events. The query is upgraded to explicitly process and check records so they can't break the main logic. To implement input validation, we add two initial steps to a query. We first make sur...
isValidNumberPrecise respects the validationNumberTypes option, which is set to ["MOBILE"] by default, meaning it will only return true for mobile numbers. If isValidNumberPrecise returns false, and you'd like more detail, you can then use the getValidationError method to get more information...
For validation to be relevant, you’re typically doing TwoWay data binding—meaning that, in addition to data flowing from the source property into the target property for display, the edited data also flows from target to source as shown in Figure 1....
