Validating form in php Web cams no log in
In the following code we have added some new variables: $name Err, $email Err, $gender Err, and $website Err.These error variables will hold error messages for the required fields.The easiest and safest way to check whether an email address is well-formed is to use PHP's filter_var() function.
Beyond the perimeter is everything considered potential enemy territory which is...literally everything other than the literal code executed by the current request.
For example, “req” means required, “alpha” means allow only alphabetic characters and so on.
Each field in the form can have zero, one or more validations.
When there are many fields in the form, the PHP validation script becomes too complex.
Moreover, since you are doing the same or similar validation for most of the forms that you make, just too much of duplicate effort is spent on form validations.
