Validating input php Chat sexy kamer
HTML5 defines a range of built-in functionality to validate common types of input, such as email addresses and dates.In some situations, such as validating custom controls or supporting legacy browsers, additional scripting may be necessary to validate user input.The “validation descriptor” is a string specifying the type of validation to be performed.For example, “req” means required, “alpha” means allow only alphabetic characters and so on.
Client-side validation alone does not ensure security; therefore data needs to be validated on the server-side as well.The second argument is the validation descriptor that tells the type of the validation required.The third argument is the error message to be displayed if the validation fails.There are a lot of places a user can change your data, so the best way to look at it is so: if you’re using a piece of data that you did not create and are not in control of every step of the way, you need to validate it.As a side note, filtering, validating, and escaping data are technically speaking three different things, but for simplicity sake, when I refer to validatation, I’m really refering to some or all of those aspects.
