* The getValidator() method will take an array of fields from the request body, iterates through them,
|
||
|
|
* and dynamically adds validation rules for them. Depending on parameters, it may or may not generate
|
||
|
|
* a form structure for rendering purposes.
|
||
|
|
*
|
||
|
|
* This method is mostly meant by internal use by means of static proxies (Facades), in order to reduce code repetition;
|
||
|
|
* Using it outside it's directed scope may cause unexpected results; For instance, the method expects inputs to be in array format, e.g. myFieldNameID1[],
|
||
|
|
* myFieldNameID2[], and so on and so forth.
|
||
|
|
*
|
||
|
|
* This isn't checked by the code yet, but if you're implementing it this way in the HTML markup, make sure it's consistent (e.g. use a loop).
|
||
|
|
*
|
||
|
|
* P.S This method automatically ignores the CSRF token for validation.
