Form field validation

When a custom form is used, you can use the following function to get all values from that form and also the information if it is valid:

_c2._base.getFormValues("#<customform id>")

On each of the fields on that form, you can add the following JSON field (entry) to add a validation:

fldvalidation  <string>

The fldvalidation string can contain multiple rules e.g.:

<rulename>:<value>~<rulename>:<value>

The rules are separated with a ~

rulenames:

• pattern_test
  the value can be a regex that tests the value(s) against.
  Note: if there are multiple values, ALL values are tested (e.g. checkbox and multiselect fields)
  
  
• min_value_length
  the value is the minimum length that the value must have in order to pass validation
  Note: if there are multiple values, ALL values are tested (e.g. checkbox and multiselect fields)
  
  
• max_value_length
  

  the maximum length of the value that is allowed.
  

  Note: if there are multiple values, ALL values are tested (e.g. checkbox and multiselect fields)

  
  
• larger_then
  The value from the field must be larger then the validation value.
  Note:
  - if there are multiple values, ALL values are tested (e.g. checkbox and multiselect fields)
  - This is not a length test, it is a simple > test.   (  value "1" > validation value "01"   will PASS )
  
  
• larger_or_eq_then
  see larger then
  
  
• smaller_then
  see larger then
  
  
• smaller_or_eq_then
  see larger then
  
  
• equal_to
  uses === to test the value against the validation value.
  
  
• not_equal_to
  uses !== to test the value against the validation value.
  
  
• min_nr_of_values
  multiselects and checkboxes can have multiple values, with this settings you can determine the minimum items they should select in order to pass validation
  
  
• max_nr_of_values
  multiselects and checkboxes can have multiple values, with this settings you can determine the maximum allowed items they can select in order to pass validation
  
  
• values_must_contain_one_of
  This is a multivalue test, so the values must be separated by a ,
  

NOTE:

You can have the value of the field tested against MULTIPLE rules.
