Informations about the package validator
Validator Class
This is a simple validator class. It can be used without dependancies, but extends the database class. It is based on https://github.com/devwithkunal/php-validator-class.
Basic Use
Create the class instance. The constructor parameter is an associative data array to be validated containing key value pairs of field names and values. If the $data is not specified, the class attempts to pull in POST data, then GET data.
Run validation checks by chaining methods to the field() method. The field() method must start every method chain.
Check if the data is valid using the isValid() method.
Basic Methods
To start validation of a field, use the field() method. Once all validations are performed, use the isValid() method to determine if they were successful.
| Method | Description |
|---|---|
field($name, $alias) |
Set the field name to start validation.$name - Name of the field/key to validate.$alias - Alias to use in error messages instead of the field name. |
